Replaced old i386_EXCEPTION_STATE_* definition with +x86_EXCEPTION_STATE32_*. Add X86_64 for exc_state.faultvaddr. + + +== [7.0alpha7] 2006-09-19 == + +* More 6.7 changes. +* Declare GC_dump() in gc.h. +* Add --enable-large-config, which just defines the LARGE_CONFIG macro. +* Make GlobalAlloc address alignment a bit more intuitive (thanks to +Charles Mills). +* Use #elif in the definitions of GET_MEM. +* Overhaul porting.html. Remove corresponding text from README. +* Fix typo in DARWIN section of gcconfig.h. +* Fix Darwin thread memory leak (thanks to Bruce Mitchener). +* Update x86 AO_test_and_set implementation to use "=q". +* Add $(EXEEXT) to many tests in tests/tests.am. (Corresponds to a +6.7 fix, which no longer applied.) +* Fix Darwin/PPC port. +* Fix Cygwin/threads port. +* Fix gcj malloc support. +* For GNU-style make, don't build libatomic_ops unless threads are requested. +This should allow single-threaded builds on platforms which do not +currently support libatomic_ops. +* Clean up and hopefully fix the CFLAGS calculation for GNU build. +(Substantially improves things on HP/UX.) +* Integrated Andrei Polushin's Visual C++ patches. These provide for +stack traces, better C++ debug support, and better log file handling. +Note that these change the location of the log file to a the path of the +executable with a .log extension. To get the old behavior back, define +OLD_WIN32_LOG_FILE. For the time being, I'm checking his project +files and the like into a windows-untested subdirectory. They +are almost certainly already out of date, but better than what we had +before. +* Fixed some win32 threads bugs, and added support for _beginthreadex. +* Fix zero size thread local allocation so that explicit deallocation +works correctly. +* Removed serious bug in GC_malloc_uncollectable(large size). +* Do not try to do thread-local gcj allocation in incremental mode. There +are races in setting up the descriptor. +* Add GC_INIT() to middle.c, fix some more GC_printfn calls. +* Some assertions erroneously used I_HOLD_LOCK() negatively, even though +it can now spuriously return TRUE. +* Rename SUNOS5 macro and OS name to SOLARIS and SUNOS5DL to SOLARISDL. +* On Linux and some Un*x variants, allocate memory by first trying sbrk, +and then switching to mmap if that fails. +* Fixed /proc/x/maps reading to deal with asynchronous deletions. +* Fix REDIRECT_MALLOC with threads on Linux. It now usually seems to work +with ugly hacks that include having calloc behave differently when it is +called from ld.so or the pthreads library. A reasonable amount of +infrastructure was added to support some of this. (Thanks to Roland McGrath +for ideas and information.) +* Import various updated build scripts. +* Add GC_register_has_static_roots_callback (thanks to Andrew Haley). +* Fix serious bugs in GC_malloc_atomic_uncollectable(). +* Return GC_SUCCESS form GC_get_stack_base(). +* Fix several atomic_ops problems on IA64 with HP Compiler. +* Update to atomic_ops-1.2. +* Fix hb_n_marks description and reclaim.c assertion. +* Various additional win32 threads fixes. +* Enable GC_ASSERTIONS for Debug build with NT_THREADS_MAKEFILE. + + +== [7.0alpha5] 2005-09-29 == + +* More 6.6, 6.7 changes. +* Some Solaris fixes, including some more general changes in how +the assembly pieces of mach_dep.c are handled. +* Removed a lot of SOLARIS_THREADS-specific code that was only +needed with the old implementation. This included many (mostly no-op) +versions of GC_is_fresh. +* Don't use atomic_ops in gc_locks.h unless we need threads. +* Fixed USE_MARK_BITS, which is once again the default without PARALLEL_MARK. +* Removed Solaris GC_INIT hack. It's a workaround for a long dead bug, +and it seemed to be wrong anyway. +* Changed win32_threads.c to require preprocessor-based interception +of thread routines by default. A client call to GC_use_DllMain is +now required to get the old behavior in which DllMain is used to implicitly +register threads. This was done for uniformity with other platforms, and +because the DllMain solution seemed to require very tricky code which, +at least in the past, imposed hard bounds on the number of threads. +* Many small changes to make thread support work again on Cygwin. +* Moved definition of allocator lock etc. to pthread_support.c and +win32_threads.c for those two cases. +* Got rid of the FASTLOCK() machinery. It doesn't seem useful on modern +platforms. +* Cleaned up the uncollectible allocation routines, speeding up the +slower paths. The code did enough unnecessary work off the critical path +that the underlying logic was getting hard to extract. +* No longer turn off THREAD_LOCAL_ALLOC with DBG_HDRS_ALL. Indications +are it just works, and I think the reasons for it not working disappeared +a while ago. +* Fixed bugs in hb_n_marks calculation and assertion. +* Don't use __builtin_expect for pre-3.0 gcc. +* Define GWW_VDB only for recent Microsoft tool chains. +* Add overview.html to doc directory. +* Fix NT_STATIC_THREADS_MAKEFILE, various compiler warnings. +* Made thread local allocation sort of work with Cygwin. The code should +be there to deal with other Windows variants, But non-Cygwin Windows +threads need more bug fixes. + + +== [7.0alpha4] 2005-08-02 == + +* Various 6.5, 6.6 changes. +* Removed GC_brief_async_signal_safe_sleep and used atomic_ops instead +(thanks to Ben Maurer). +* Integrated build patches from Davide Angelocola and Petter Urkedal. +* Fix dynamic-linker-based pthread call redirection. +* Renamed RS6000 to POWERPC/AIX. +* Allow recovery from SIGSEGV in marker on Linux. This works around +a race in thread stack marking if /proc is used to find roots. We do +that by default with malloc redirection and threads. This involved +moving some GC_find_limit and SETJMP related declarations to gc_priv.h. +* Added doc/porting.html file. +* Added ADD_HEAP_GUARD_PAGES for sbrk/*nix platforms to debug extreme +memory overwrite errors. +* Added trivial NO_INCREMENTAL flag to facilitate debugging. +* Added GC_getattr_np-based GC_get_stack_base (untested). +* Separated thread local allocation into a separate file and added the +beginning of win32 support for that. + + +== [7.0alpha3] 2005-04-28 == + +* Added support for dlopen-based interception of pthread functions. +This is only half done. The gc.h redefinitions currently interfere. +* Integrated major automake overhaul from Petter Urkedal. + + +== [7.0alpha2] 2005-04-07 == + +* GC_bytes_allocd was incremented by a possibly uninitialized variable +in GC_generic_malloc_inner. (Bug introduced in gc7.0alpha1. Thanks +to Ben Hutchings for tracking it down.) +* Win32 fixes (thanks to Ben Hutchings and Maurizio Vairani). +* Integrated Ben Hutchings' GetWriteWatch-based virtual dirty bit +implementation for win32. +* Removed pc_gc.tar and floppy targets in Makefile.direct. Removed +pc_excludes file. +* No longer include GC_bytes_wasted when evaluating allocation progress. +Since we are now counting live memory, it no longer makes sense. +* Applied Davide Angelocola's configure patch. There are now separate +Makefile.am's in the cord and tests subdirectory, more tests, etc. +* Renamed configure.in to configure.ac. +* Merged a very small number of Nathanael Nerode's configure.ac +cleanups from the gcc tree. Unfortunately, that file is a bit +different from ours. +* Changed EINTR handling in sem_wait slightly. +* Restructure the root marking code. Remove all traces of +USE_GENERIC_PUSH_REGS, and effectively make it the default. +Make it easier to pass a context pointer to the mark routine, in +case we ever want to do precise stack marking. +* Replace GC_start_blocking() and GC_end_blocking() with GC_do_blocking(). +This remains undocumented, and only implemented for pthreads. But it +removes an otherwise unavoidable race with stores of callee-save +registers. +* Fix GC_n_mark_bits for the default MARK_BIT_PER_GRANULE case. This +resulted in bogus complaints in heap dumps. +* Upgrade to libatomic_ops-1.0, and update build structure to match. +* Remove SRC_M3 support. Clean up lock initialization code in misc.c. +* Removed gc_local_alloc.h. If THREAD_LOCAL_ALLOC is defined, the +thread local allocation routines are now called automatically. +* Renamed gc_inl.h back to gc_inline.h. Changed the interface appreciably +since locking has turned into a dominant issue, and in-line allocation +only makes sense if it's no worse than thread-local allocation. +Gc_inline.h is now also used to implement thread-local allocation. +* Finished replacing stubborn allocation with manual write barrier. +Untested. +* Use thread-local allocation code by default. +* Added GC_register_my_thread and friends for Posix and win32. +* Patch for GWW_VDB from Ben Hutchings. +* Removed explicit THREAD_LOCAL_ALLOC tests, since that now always +redefines GC_malloc. +* Removed now unused AIX memory allocation code. +* Various minor fixes for bugs introduced in 7.0alpha1. + + +== [7.0alpha1] 2004-11-09 == + +* Remove GC_PROTO, VOLATILE, GC_PTR, and GC_CONST. Assume ANSI C compiler +and use ANSI constructs unconditionally. +* Introduce #elif and #error in some of the appropriate places. +* Remove GC_printf cruft. Use stdargs. +* Remove separate Solaris threads support. Use the more generic Posix +implementation. +* Use atomic_ops for atomic operations and memory barriers. +* Clean up MPROTECT_VDB implementation. Use SA_SIGINFO wherever +possible. +* Remove broken SIGNALS stuff. +* Use size_t instead of word, where appropriate. +* Add .S.o rule to Makefile.am. +* Officially discontinue SunOS4, several old flavors of M68K (SunOS4, +A/UX, HP), IBM PC/RTs and RISCOS/Irix4. (I doubt the old code worked. +If anyone cares, these should be easy to resurrect.) +* Add EXPECT() in some critical places. +* Redefined hb_sz and hb_body to deal with bytes rather than words. +This affected a great deal of code. I would like to consistently use +byte offsets and sizes where there's not a convincing reason to do +otherwise. +* Redefined several other variables (GC_mem_found, GC_words_allocd) +etc. to use units of bytes. Most of these were also renamed to +reflect that fact. +* Killed as many "register" declarations as possible. +* Partially replaced stubborn allocation with manual write barrier. +It's currently broken. +* Restructured mark code, to allow mark bits to be kept either on +a per allocation granule or per object basis. The emphasis is +now on the -DUSE_MARK_BYTES option, since individual bits perform +quite badly on hyper-threaded P4s, and are probably suboptimal on +other architectures. -DUSE_MARK_BITS is currently broken, and may +be resurrected only for the single-threaded case. This significantly +reduced the cache footprint required by auxiliary GC data structures. +It also reduces space overhead for small heaps. It probably slows +things down slightly if interior pointers are very common. +* As part of the above, we now maintain an approximate count of set +mark bits in each heap block. +* As part of the above, the semantics of hb_map changed drastically. +For MARK_BIT_PER_OBJ, it doesn't exist. For MARK_BIT_PER_GRANULE, +it is purely a way to replace a mod instruction with a table lookup. +(Somewhat to my surprise, this still wins on modern hardware.) +* Removed PRINTSTATS, GATHERSTATS, and SILENT macros. Everything is +now controlled by GC_print_stats variable and GC_PRINT_STATS +and new GC_PRINT_VERBOSE_STATS environment variables. +* Add GC_log_printf and use it consistently for logging output. +* Unconditionally count the objects we reclaim in the sweep phase. +For thread local allocation, we need that anyway, and we expect +that's increasingly the only case that matters. And it simplifies +the code. In general expect minor performance hacks that benefit +only the single-threaded case to disappear. +* Remove GC_quiet from gc.h and elsewhere. +* Changed the heap expansion heuristic, and the definition of +GC_free_space_divisor, to refer to live data size, instead of total +heap size. I believe this is much more robust. It wasn't previously +possible, because we didn't have access to live data size. +* Thread local allocation added the extra byte in twice: Once in +thread_local_alloc, and once in malloc_many. +* Removed GC_malloc_words_small and GC_gcj_fast_malloc. A new +mechanism based on the thread local allocation data structures +is expected to be added instead. This should allow inlined code +that is both fast and doesn't rely on collector internals. +* Changed both free lists and reclaim lists to be indexed by granules +instead of words, norming halving their size. +* MERGE_SIZE is now the only option, and the macro was removed. +(Without it, we need a memory reference to GC_all_interior_pointers +anyway. Thus it costs us nothing.) +* Change GC_size_map to map to granules instead of words. Make sure +that every possible size up to TINY_FREELISTS is present. +* Split of macros need for fast inline allocation into gc_tiny_fl.h +in anticipation of a new inline allocator that doesn't rely on GC +internals. +* Changed thread local allocation to use GRANULE_BYTES and TINY_FREELISTS +in anticipation of a merge with the inline allocation code. +* Removed ALIGN_DOUBLE. This is mostly handled by GRANULE_BYTES. +* Make locking on most platforms conditional on GC_need_to_lock. + + +== [6.9] == + +* Fix typo in PREFETCH implementation for X86_64 (thanks to Peter Wang). +* Fix M68K LINUX port (thanks to Debian packagers). +* __GNUC__ was misspelled as __GNUC in new_gc_alloc.h (thanks to Peter Wang). +* Integrated Allan Hsu's patch for OS X VM deallocation problems. +* Applied FreeBSD/X86_64 patch. + + +== [6.8] 2006-07-08 == + +* Added some support for Dragonfly BSD (thanks to Joerg Sonnenberger and +Thomas Klausner). +* Improvements to the HP/UX section of configure.in/configure.ac (thanks +to Andreas Tobler). +* GC_unix_get_mem could neglect to release the malloc lock on Irix, under +extremely unlikely circumstances. (Thanks to Jean-Baptiste Nivois for +some careful code inspection.) +* Added support for kFreeBSD + glibc (thanks to Petr Salinger). +* Fix more MacOS threads memory leaks (thanks to Allan Hsu). +* Added initial Solaris/x64 support (thanks to Rainer Orth). + + +== [6.7] 2006-03-03 == + +* Add "int" to Solaris "end" and "etext" declaration in gc.h. Declared +the symbols with underscores and as arrays, since that's what's actually +used. Perhaps this could all just be removed. (Thanks to John Bowman.) +* Fixed ARM GC_test_and_set code (thanks to Kazu Hirata and Paul Brook). +* Added casts for assignments to hb_last_reclaimed, which truncate the +value. Added a cast to GC_adj_words_allocd. Use GetModuleHandleA +when retrieving a handle to kernel32.dll under win32. +* Added Tandem S-Series support. (Thanks to Craig McDaniel. A modified +version of his patch was applied, and hence breakage is probably not +his fault.) +* Remove spurious gc:: qualifier for operator delete[] in gc_cpp.h (thanks +to Hanno Boeck). +* Changed a test for LINUX in config_macros.h to one for __linux__. +* Add prototypes for GC_finalizer_notifier and GC_thr_init (thanks to +David Ayers). +* Use ld instead of nonexistent ldz instruction in Darwin FindTopOfStack +(thanks to Andreas Tobler). +* Add support for Darwin/x86 (thanks to Geoff Norton and the Mono +developers). +* Merge in some recent gcc fixes. Add ppc64 asm code. (Thanks to +Bryce McKinlay and other GCJ developers.) +* Scan MEM_PRIVATE sections under Windows ME and predecessors. +* Interior pointers with some largish offsets into large objects could +be ignored, if GC_all_interior_pointers was set. (Oddly this worked +correctly for stack references if it was not set. Otherwise it failed +for both stack and heap references. Thanks to Andrew McKinlay for the +critical test case.) +* Integrated Tatsuya Bizenn's NETBSD threads support, with some +untested changes. +* Added GC_strdup and friends to make leak detection work correctly +for strdup clients (thanks to Jon Moore). Fixed the existing strdup +with malloc redirection to handle a null malloc return correctly. + + +== [6.6] 2005-09-09 == + +* Fix CPU count detection for Irix and FreeBSD (thanks to Dan Bonachea). +* Integrate Dan Bonachea's patch for the IBM XLC compiler on Darwin. +* Integrated Andreas Tobler's FreeBSD/PowerPC patch. +* Don't access the GC thread structure from the restart handler. It's +unsafe, since the handler may run too late. (Thanks to Ben Maurer for +tracking this down.) +* Applied Christian Thalinger's patch to change comment syntax in +alpha_mach_dep.S. +* Added test for GC_no_dls in GC_dyld_image_add for DARWIN (thanks to +Juan Jose Garcia-Ripoll). +* Use LINUX_STACKBOTTOM for Linux/SH and LINUX/ARM (thanks to +Sugioka Toshinobu and Christian Thalinger). +* Rewrote GC_parse_map_entry. This assumed a fixed column layout of +/proc/self/maps on Linux. This ceased to be true about 2 years ago. +The old code is probably quite problematic with -DREDIRECT_MALLOC. It +is also used by default for IA64, though I haven't seen actual failures +there. +* More consistently define HBLKSIZE to 4096 on 64 bit architectures with +4K pages (thanks to Andrew Haley). +* With win32 threads, GC_stop_world needs to acquire GC_write_cs (thanks +to Ben Hutchings for the observation and patch). +* Move up struct callinfo declaration to make gcc 4.0.2 happy. + + +== [6.5] 2005-05-22 == + +* Integrated Paolo Molaro's patch to deal with EINTR in sem_wait. +* Make GC_approx_sp() write to dummy location to ensure that stack +is grown here, when sp looks reasonable, rather than later, when +it might look like a bad memory reference. (Problem was never +observed that I know of. But on rereading the code it seemed +dubious.) +* Separate out GC_with_callee_saves_pushed and sometimes call +it from GC_suspend_handler in pthread_stop_world.c. Callee-save +register values sometimes failed to get traced under HP/UX on +PA-RISC. Linux/IA64 had the same problem, though non-stacked +callee-save registers seem to be so rarely used there that nobody +ever noticed. +* Integrated an ancient Darwin powerpc_darwin_machine_dep.s patch +from Andreas Tobler, which I had lost. +* Fix compare_and_exchange implementation for gcc/IA64 to deal with +pickier compiler versions. +* Fixed Itanium 32-bit ABI support (HP/UX). In particular, the +compare_and_exchange implementation didn't consider that possibility. +* Undefine GC_pthread_detach in win32_threads.c (thanks to +Tommaso Tagliapietra). +* Fixed inclusion of frame.h for NETBSD in os_dep.c. +* Applied Dan Bonachea's patch to use mmap on AIX. +* Several fixes to resurrect the Irix port on recent OS versions. +* Change ALPHA to use LINUX_STACKBOTTOM. +* Change SPARC64/LINUX to also use LINUX_STACKBOTTOM. Deal with potential +bad values of __libc_stack_end on that platform (thanks to David Miller). +* Relax gctest to allow larger heap if ALIGN_DOUBLE isn't set. +(Unnecessary in 7.0) +* Force a define of __STDC__=0 for the IBM compiler on AIX, so that +we get prototypes. (Unnecessary in 7.0) +* GC_INIT definition for AIX and CYGWIN referred to DATASTART and DATAEND +which are only defined in private include files. +* Integrated some small gcconfig.h patches from Dan Bonachea. Also +relaxed assertion about FreeBSD stack size in pthread_support.c. +* Integrated Andrew Begel's darwin_stop_world.c patch for 64-bit +support. This may need additional work. +* Avoided potentially infinite recursion in GC_save_callers if +the system backtrace calls malloc. The workaround currently requires +__thread support if this code is used with threads. +* Avoided another similar infinite recursion by conditionally +invoking GC_save_callers in alloc.c (thanks to Matthias Andree +for helping to track down both of these). +* Removed all traces of aix_irix_threads.c. AIX and Irix now use +pthread_support.c and pthread_stop_world.c. The old code appeared +to be unreliable for AIX, and was not regularly maintained. +* On Irix, ignore segments with MA_FETCHOP or MA_NOTCACHED attributed; +they're not always safe to read. +* Fixed a previously vacuous assertion (diagnosed by the SGI compiler) +in GC_remove_from_fl. +* Fix stack_size assertion in GC_pthread_create. +* Fix assertion in GC_steal_mark_stack. + + +== [6.4] 2004-12-21 == + +* Merge gcconfig.h changes from gcc tree. +* Unconditionally include gc_priv.h in solaris_pthreads.c, win32_threads.h, +aix_irix_threads.c, and solaris_threads.c to get thread definitions. +* Start marker threads in GC_thr_init, so that they get started even +if no other threads are ever started. (Oddly enough, the parallel +collector worked correctly, though not well, with no helper threads.) +* Go ahead and split large blocks in GC_allochblk_nth if GC_dont_gc +is set (thanks to Alexander Petrossian). +* GC_PRINT_BACK_HEIGHT would deadlock with thread support. +* Let in_progress_space in backgraph.s grow dynamically. +* Fix README.solaris2. The GC_thr_init() hack doesn't work anymore. +* Convert GC_finalizer_mem_freed to bytes in allchblk.c. +* Add missing declaration for GC_generic_malloc_words_small_inner. +Without it, s390x breaks. (Thanks to Ulrich Weigand.) +* Applied several MacOSX patches to support older tool chains (thanks +to Stefan Ring). +* Bug fix for NetBSD/x64 (thanks to Marc Recht). +* Add NetBSD/sh3 support (thanks to Uchiyama Yasushi). +* Fixed an uninitialized variable in cordprnt.c. +* Eliminated some, but not all, gcc -Wall warnings. +* Changed some old style casts to reinterpret_cast in new_gc_alloc.h +(thanks to Dan Grayson). +* GC_extend_size_map shouldn't adjust for GC_all_interior_pointers if +GC_DONT_ADD_BYTE_AT_END is set. +* Changed some (long) casts to (word) in preparation for Win64 (thanks +to Peter Colson). +* Changed "int stack_size" declaration in pthread_support.c to use +size_t. (Only mattered with GC_ASSERTIONS enabled.) +* Added CRIS (etrax) support (thanks to Simon Posnjak and Hans-Peter Nilsson). +* Removed GC_IGNORE_FB frame buffer recognition, and replaced +it with a check that the mapping type is MEM_IMAGE. +In theory, this should work much better, but it is a high +risk change for win32. (Thanks to Ashley Bone for the crucial +experimental data behind this, and to Rutger Ovidius for +some further experiments.) +* GC_allochblk_nth incremented GC_words_wasted by bytes rather than +words. +* Consider GC_words_wasted in GC_adj_words_allocd only if it is within +reason. (A hack to avoid some extremely unlikely scenarios in which +we manage to allocate only "wasted" space. 7.0 has a better fix.) +* Changed PowerPC GC_clear implementation to use lwsync instead of +eieio, since the documentation recommends against eieio, and +it seems to be incorrect if the preceding memory op is a load. +* Fixed print_block_list to print the correct kind number for +STUBBORN (thanks to Rutger Ovidius). +* Have configure.in generate an error if it is asked to support +pthreads, but doesn't know how to. +* Added Kazuhiro Inaoka's patch for Renesas M32R support. +* Have the GNU build mechanism link with -ldl. Rename THREADLIBS +to THREADDLLIBS to reflect this. (Thanks to Sven Verdoolaege.) +* Added Hannes Mehnert's patch for FreeBSD/SPARC support. +* Merged some FreeBSD specific patches to threadlibs.c and dyn_load.c. +(Thanks to John Merryweather Cooper.) +* Define MPROTECT_VDB on MACOSX only if threads are being used, since the +dirty page tracking mechanism uses threads. (This avoids an undefined +reference to _GC_darwin_register_mach_handler_thread.) +* By popular demand, use __libc symbols only if we are built with +USE_LIBC_PRIVATES, which is off by default, and not otherwise documented. +* Ignore GC_enable_incremental() requests when KEEP_BACK_PTRS is set. +The GC itself will dirty lots of pages in this cases, probably making +it counterproductive on all platforms. And the DARWIN port crashes. + + +== [6.3] 2004-07-08 == + +* Compile test_cpp.cc with CXXCOMPILE instead of COMPILE. +* Very large allocations could cause a collector hang. Correct +calculation of GC_collect_at_heapsize. +* GC_print_hblkfreelist printed some bogus results if USE_MUNMAP +was defined. +* Include gc_config_macros.h in threadlibs.c. +* Correct MacOSX thread stop code (thanks to Dick Porter). +* SMALL_OBJ definition was off by one. This could cause crashes +at startup. (Thanks to Zoltan Varga for narrowing this down to +a trivial test case.) +* Integrate Paolo Molaro's patch to deal with a race in the Darwin +thread stopping code. +* Changed X86_64 implementation to use SA_SIGINFO in the MPROTECT_VDB +implementation. The old approach appears to have been broken by +recent kernels. +* Added GC_ATTR_UNUSED to eliminate a warning in gc_allocator.h (thanks +to Andrew Begel). +* Fix GC_task_self declaration in os_dep.c (thanks to Andrew Pinski). +* Increase INITIAL_BUF_SZ in os_dep.c for Solaris /proc reads. + + +== [6.3alpha6] 2004-05-06 == + +* Define USE_GENERIC_PUSH_REGS for NetBSD/M68K. +* Fixed the x64 PREFETCH macros to correctly handle ia32e (which uses +different prefetch instructions on x64). (Thanks to H.J. Lu.) +* GC_config_macros.h did not correctly define GC_WIN32_THREADS from +GC_THREADS. +* Added simple_example.html. +* Merged Andrew Gray's patch to correctly restore signal handlers on +FreeBSD. +* Merged a patch from Andreas Jaeger to deal with prefetch-related warnings +on x86-64. Added some other casts so that the PREFETCH macros +always get a ptr_t argument. Removed some casts in the PREFETCH +implementations. +* Added a header guard for gc_allocator.h and changed GC_debug_free to +clobber contents of deallocated object (suggested by Jesse Jones). +* The signal masking code in pthread_stop_world.c contained some errors. +In particular SIGSEGV was masked in the handler, in spite of the fact that +it wrote to the heap. This could lead to an uncaught SIGSEGV, which +apparently became much more likely in Linux 2.6. Also fixed some +typos, and reduced code duplication in the same area. +* Remove ltconfig, clean up configure messages for DG/UX (thanks to +Adrian Bunk for the patches). +* Integrated NetBSD/OpenBSD patches from Marc Recht and Matthias Drochner. + + +== [6.3alpha5] 2004-03-30 == + +* Fix & vs && typo in GC_generic_malloc and +GC_generic_malloc_ignore_off_page. (Propagated from the gcc tree.) +* Removed SA_NODEFER hack from NetBSD and Solaris write-protect handler. +(According to Christian Limpach, the NetBSD problem is fixed. +Presumably so is the Solaris 2.3 problem.) +* Removed placement delete from gc_cpp.h for the SGI compiler (thanks +to Simon Gornall for the patch). +* Changed semantics of the GC_IGNORE_FB environment variable, based +on experimentation by Nicolas Cannasse pointing out that the old +interpretation was useless. We still need help in identifying win32 +graphics memory mappings. The current "solution" is a hack. +* Removed "MAKEOVERRIDES =" from Makefile.am and thus Makefile.in. +It probably made more sense in the gcc context. +* Explicitly ensure that NEED_FIND_LIMIT is defined for {Open,Net}BSD/ELF. +* Replaced USE_HPUX_TLS macro by USE_COMPILER_TLS, since gcc often +supports the same extension on various platforms. +* Added some basic (completely untested) defines for Win64, in support +of future work. +* Declared GC_jmp_buf in os_dep.s as JMP_BUF instead of jmp_buf, fixing +a memory overwrite bug on Solaris and perhaps other platforms. +* Added 0 != __libc_stack_end test to GC_linux_stack_base (thanks to +Jakub Jelinek for the patch and explaining the problem). +Otherwise pre-linking could cause the collector to fail. +* Changed default thread local storage implementation to USE_PTHREAD_SPECIFIC +for HP/UX with gcc. The compiler-based implementation appears to work +only with the vendor compiler. +* Export GC_debug_header_size and GC_USR_PTR_FROM_BASE from gc_mark.h, +making client mark code cleaner and less dependent on GC version. +* Export several new procedures and GC_generic_malloc from gc_mark.h +to support user-defined kinds. Use the new procedures to replace existing +code in gcj_mlc.c and typd_mlc.c. +* Added support for GC_BACKTRACES. +* Fixed a remaining problem in CORD_str with signed characters (thanks +to Alexandr Petrosian for the patch). +* Removed supposedly redundant, but very buggy, definitions of finalizer +macros from javaxfc.h. Fortunately this file probably has no users. +The correct declarations were already in gc.h. +* Also need to set GC_in_thread_creation while waiting for GC during +thread termination, since it is also possible to collect from an +unregistered thread in that case. +* Define NO_GETENV for Windows CE, since getenv doesn't appear to exist. +Plus some other minor WinCE fixes (thanks to Alain Novak). +* Added GC_register_describe_type_fn. +* Arrange for debugging finalizer registration to ignore non-heap +registrations, since the regular version of the routine also behaves +that way. +* GC_gcj_malloc and friends need to check for finalizers waiting to be run. +One of the more obscure allocation routines with missing a LOCK() call. +* Fixed cvtres invocations in NT_MAKEFILE and NT_STATIC_THREADS_MAKEFILE +to work with VS.NET. +* Cleaned up GC_INIT calls in test. Updated gc.man to encourage GC_INIT +use in portable code. +* Taught the GC to use libunwind if --enable-full-debug is specified on +IA64 and libunwind is present. +* The USE_MUNMAP code could get confused about the age of a block and +prematurely unmap it. GC_unmap_old had a bug related to wrapping of +GC_gc_no. GC_freehblk and GC_merge_unmapped didn't maintain +hb_last_reclaimed reasonably when blocks were merged. The code was +fixed to reflect original intent, but that may not always be an +improvement. + + +== [6.3alpha4] 2004-01-01 == + +* USE_MMAP was broken by confusion in the code dealing with USE_MMAP_ANON. +* Darwin support was broken in alpha3 as a result of my mis-integration of +Andrew Begel's patches. Fixed with another patch from Andrew Begel. +* A new sanity check in pthread_stop_world.c:GC_push_all_stacks() was +overly aggressive. We may collect from an unregistered thread during +thread creation. Fixed by explicitly checking for that case. (Added +GC_in_thread_creation.) + + +== [6.3alpha3] 2003-12-20 == + +* Removed -DSMALL_CONFIG from BCC_MAKEFILE. +* Changed macros to test for an ARM processor (Patch from Richard Earnshaw.) +* Mostly applied a DJGPP patch from Doug Kaufman. Especially Makefile.dj +had suffered from serious bit rot. +* Rewrote GC_apply_to_maps, eliminating an off-by-one subscript error, +and a call to alloca (for lcc compatibility). +* Changed USE_MUNMAP behavior on POSIX platforms to immediately remap +the memory with PROT_NONE instead of unmapping it. The latter risks +an intervening mmap grabbing the address space out from underneath us. +Updated this code to reflect a cleaner patch from Ulrich Drepper. +* Replaced _T with _Tp in new_gc_alloc.h to avoid a MACOS X conflict. +(Patch from Andrew Begel.) +* Dynamically choose whether or not lock should spin on win32 (thanks +to Maurizio Vairani for the patch). This may be a significant performance +improvement for win32. +* Fix Makefile.direct to actually include NT_STATIC_THREADS_MAKEFILE +in the distribution (thanks to Maurizio Vairani). +* Maybe_install_looping_handler() was accidentally exported, violating +our name space convention. +* Made os_dep.c use sigsetjmp and SA_NODEFER for NetBSD. (Thanks to +Christian Limpach. I generalized the patch to use sigsetjmp on all +UNIX_LIKE platforms, admittedly a slightly risky move. But it may avoid +similar problems on some other platforms. I also cleaned up the definition +of UNIX_LIKE a bit.) +* Integrated Andrew Begel's Darwin threads patch, adjusted according to +some of Fergus Hendersons's comments. (Patch didn't apply cleanly, +errors are possible.) +* Added another test or two for the Intel 8.0 compiler to avoid +confusing it with gcc. The single-threaded collector should now build +with icc, at least on ia64. + + +== [6.3alpha2] 2003-11-04 == + +* Re-enabled I_HOLD_LOCK assertion in aix_irix_threads.h. +* Put back the WINABI qualifier for GC_CreateThread. (Thanks to +Danny Smith for the patch. 6.3alpha1 had the qualifier in one place +but not elsewhere, which was clearly wrong.) +* Sometimes explicitly define __private_extern__ before DARWIN dyld.h +include. (Thanks to Andreas Tobler for posting the patch.) +* Included signal.h from pthread_support.c. Removed GC_looping_handler, +which was dead code. +* GC_find_start was misdeclared by gc_pmark.h if PRINT_BLACK_LIST was +defined (thanks to Glauco Masotti for testing and reporting this). +Changed GC_find_start to never just return 0. According to its +comment it doesn't, and it's unclear that's correct. +* GC_alloc_large had several largely compensating bugs in the +computation of GC_words_wasted. (It was confused about bytes vs. +words in two places.) +* Integrated Slava Sysoltsev's patch to support more recent versions of +the Intel compiler on IA64/Linux. +* Changed win32 spinlock initialization to conditionally set a spin count. +(Emmanual Stumpf pointed out that enabling this makes a large performance +difference on win32 multiprocessors.) Also cleaned up the win32 spinlock +initialization code a bit. +* Fixed thread support for HP/UX/IA64. The register backing store base for +the main thread was sometimes not set correctly. (Thanks to +Laurent Morichetti.) +* Added -DEMPTY_GETENV_RESULTS flag to work around Wine problem. +* Declare GC_stack_alloc and GC_stack_free in solaris_threads.h to +avoid 64-bit size mismatches (thanks to Bernie Solomon). +* Fixed GC_generic_push_regs to avoid a potential and very unfortunate +tail call optimization. This could lead to prematurely reclaimed +objects on configurations that used the generic routine and the new +build infrastructure (which potentially optimizes mach_dep.c). +This was a serious bug, but it's unclear whether it has resulted in +any real failures. +* Fixed CORD_str to deal with signed characters (thanks to Alexandr Petrosian +for noticing the problem and supplying the patch). +* Merged a couple of NOSYS/ECOS tests into os_dep.c from gcj (thanks +to Anthony Green). +* Partially merged a win32 patch from Ben Hutchings, and substantially +revised other parts of win32_threads.c. It had several problems. +Under MinGW with a statically linked library, the main thread was +not registered. Cygwin detached threads leaked thread descriptors. +There were several race conditions. For now, unfortunately the +static threads limit remains, though we increased it, and made table +traversal cost depend on the actual thread count. +There is also still some code duplication with pthread_support.c. +(Thread descriptors did become much smaller, since Ben Hutchings +removed the thread context from them.) +* Integrated a Solaris configure.in patch from Rainer Orth. +* Added GC_IGNORE_FB and associated warning to very partially address +the issue of the collector treating a mapped frame buffer as part +of the root set. (Thanks to David Peroutka for providing some +insight. More would be helpful. Is there anything that can be used +to at least partially identify such memory segments?) + + +== [6.3alpha1] 2003-07-26 == + +* Integrated some NetBSD patches by Marc Recht. These +were already in the NetBSD package. +* GC_pthread_create waited for the semaphore even if pthread_create failed. +(Thanks to Dick Porter for the pthread_support.c patch.) Applied the +analogous fix for aix_irix_threads.c. +* Added Rainer Orth's Tru64 fixes. +* The check for exceeding the thread table size in win32 threadDetach +was incorrect (thanks to Alexandr Petrosian for the patch). +* Applied Andrew Begel's patch to correct some reentrancy issues +with dynamic loading on Darwin. +* GC_CreateThread() was neglecting to duplicate the thread handle in +the table (thanks to Tum Nguyen for the patch). +* Pass +ESdbgasm only on PA-RISC machines with vendor compiler (thanks to +Roger Sayle for the patch). +* Applied more AIX threads patches from Scott Ananian. + + +== [6.2] 2003-06-21 == + +* Integrated a second round of Irix/AIX patches from Dan Bonachea. +Renamed mips_sgi_mach_dep.S back to mips_sgi_mach_dep.s, since it requires +the Irix assembler to do the C preprocessing; gcc -E doesn't work. +* Fixed Makefile.direct for DARWIN (thanks to Manuel Serrano). +* There was a race between GC_pthread_detach and thread exit that could +result in a thread structure being deallocated by GC_pthread_detach +even though it was still needed by the thread exit code (thanks to +Dick Porter for the small test case that allowed this to be debugged). +* Fixed version parsing for non-alpha versions in acinclude.m4 and +version checking in version.h. +* Issues identified (not yet fixed): +- A dynamic libgc.so references dlopen unconditionally, but doesn't link +against libdl. +- GC_proc_fd for Solaris is not correctly updated in response to a +fork() call. Thus incremental collection in the child won't work +correctly. (Thanks to Ben Cottrell for pointing this out.) +- --enable-redirect-malloc is mostly untested and known not to work +on some platforms. +- There seem to be outstanding issues on Solaris/x86, possibly with +finding the data segment starting address. +- Very large root set sizes (> 16 MB or so) could cause the collector +to abort with an unexpected mark stack overflow. (Thanks to +Peter Chubb.) NOT YET FIXED. Workaround is to increase the initial +size. +- The SGI version of the collector marks from mmapped pages, even +if they are not part of dynamic library static data areas. This +causes performance problems with some SGI libraries that use mmap +as a bitmap allocator. NOT YET FIXED. It may be possible to turn +off DYNAMIC_LOADING in the collector as a workaround. It may also +be possible to conditionally intercept mmap and use GC_exclude_static_roots. +The real fix is to walk rld data structures, which looks possible. +- Incremental collector should handle large objects better. Currently, +it looks like the whole object is treated as dirty if any part of it is. + + +== [6.2alpha6] 2003-06-05 == + +* There was an extra underscore in the name of GC_save_registers_in_stack +for NetBSD/SPARC (thanks to Jaap Boender for the patch). +* Integrated Brian Alliet's patch for Darwin. This restructured the +linuxthreads/pthreads support to separate generic pthreads support +from more the system-dependent thread-stopping code. I believe this +should make it easier to eliminate the code duplication between +pthreads platforms in the future. The patch included some other +code cleanups. +* Integrated Dan Bonachea's patch to support AIX threads. This required +substantial manual integration, mostly due to conflicts with other +recent threads changes. It may take another iteration to +get it to work. +* Removed HPUX/PA-RISC support from aix_irix_threads.c. It wasn't used +anyway and it cluttered up the code. And anything we can do to migrate +towards generic pthreads support is a good thing. +* Added a more explicit test for tracing of function arguments to test.c. +* Added Akira Tagoh's PowerPC64 patch. +* Fixed some bit rot in the Cygwin port (thanks to Dan Bonachea for +pointing it out). gc.h now includes just windows.h, not winbase.h. +* Declared GC_save_regs_in_stack() in gc_priv.h. Remove other declarations. +* Changed --enable-cplusplus to use automake consistently. The old way +confused libtool. "Make install" didn't work correctly for the old version. +Previously --enable-cplusplus was broken on cygwin. +* Changed the C version of GC_push_regs to fail at compile time if it is +generated with an empty body. This seems to have been the cause of one +or two subtle failures on unusual platforms. Those failures should +now occur at build time and be easily fixable. + + +== [6.2alpha5] 2003-05-14 == + +* GC_invoke_finalizers could, under rare conditions, set +GC_finalizer_mem_freed to an essentially random value. This could +possibly cause unbounded heap growth for long-running applications +under some conditions. (The bug was introduced in 6.1alpha5, and +is not in gcc3.3.) +* Attempted to sanitize the various DLL macros. GC_USE_DLL disappeared. +GC_DLL is used instead. All internal tests are now on GC_DLL. +README.macros is now more precise about the intended meaning. +* Include DllMain in the multi-threaded win32 version only if the +collector is actually built as a dll (thanks to Mohan Embar for +a version of the patch). +* Hide the cygwin threadAttach/Detach functions. They were violating our +namespace rules. +* Fixed an assertion in GC_check_heap_proc. Added GC_STATIC_ASSERT +(thanks again to Ben Hutchings). +* Removed some obsolete definitions for Linux/PowerPC in gcconfig.h. +* CORD_cat was not rebalancing unbalanced trees in some cases, violating +a CORD invariant. Also tweaked the re-balancing rule for +CORD_cat_char_star. (Thanks to Alexandr Petrosian for the bug report +and patch.) +* Added hand-coded structured exception handling support to mark.c. +This should enable support of dynamic libraries under win32 with +gcc-compiled code. (Thanks to Ranjit Mathew for the patch.) +Turned on dynamic library scanning for gcc on Win32. +* Removed some remnants of read wrapping (thanks to Kenneth Schalk). +GC_USE_LD_WRAP was probably broken in recent versions. +* The build could fail on some platforms since gcconfig.h could include +declarations mentioning ptr_t, which was not defined, e.g. when if_mach +was built (thanks to Yann Dirson for pointing this out). Also +cleaned up tests for GC_PRIVATE_H in gcconfig.h a bit. +* The GC_LOOP_ON_ABORT environment variable interfered with incremental +collection, since the write fault handler was erroneously overridden. +Handlers are now set up in the correct order. +* It used to be possible to call GC_mark_thread_local_free_lists() while +the world was not stopped during an incremental GC. This was not safe. +Fortunately, it was also unnecessary. Added GC_world_stopped flag +to avoid it. (This caused occasional crashes in GC_set_fl_marks +with thread local allocation and incremental GC. This probably happened +primarily on old, slow multiprocessors.) +* Allowed overriding of MAX_THREADS in win32_threads.c from the build +command line (thanks to Yannis Bres for the patch). +* Taught the IA64/linux code to determine the register backing store base from +/proc/self/maps after checking the __libc symbol, but before guessing. +(__libc symbols are on the endangered list, and the guess is likely to not +always be right for 2.6 kernels.) Restructured the code to read and parse +/proc/self/maps so it only exists in one place (all platforms). +* The -DUSE_PROC_FOR_LIBRARIES code was broken on Linux. It claimed that it +also registered the main data segment, but didn't actually do so. (I don't +think anyone actually uses this configuration, but ...) +* Made another attempt to get --enablecplusplus to do the right thing. +Since there are unavoidable problems with C programs linking against a +dynamic library that includes C++ code, I separated out the c++ code into +libgccpp. + + +== [6.2alpha4] 2003-03-10 == + +* Use LINUX_STACKBOTTOM for >= glibc2.2 on Linux/MIPS. (See Debian bug +# 177204) +* Integrated Jeff Sturm and Jesse Rosenstock's MACOSX threads patches. +* Integrated Grzegorz Jakacki's substantial GNU build patch. "Make dist" +should now work for the GNU build process. Documentation files +are installed under share/gc. +* Tweaked gc_cpp.h to again support the Borland compiler (thanks to +Rene Girard for pointing out the problems). +* Updated BCC_MAKEFILE (thanks to Rene Girard). +* Added GC_ASSERT check for minimum thread stack size. +* Added --enable-gc-assertions. +* Added some web documentation to the distribution. Updated it in the +process. +* Separate gc_conf_macros.h from gc.h. +* Added generic GC_THREADS client-defined macro to set the appropriate +GC_XXX_THREADS internal macro. (gc_config_macros.h.) +* Add debugging versions of _ignore_off_page allocation primitives. +* Moved declarations of GC_make_closure and GC_debug_invoke_finalizer +from gc.h to gc_priv.h. +* Reset GC_fail_count even if only a small allocation succeeds. +* Integrated Brian Alliet's patch for dynamic library support on Darwin. +* gc_cpp.h's gc_cleanup destructor called GC_REGISTER_FINALIZER_IGNORE_SELF +when it should have called the lower case version, since it was +explicitly computing a base pointer. + + +== [6.2alpha3] 2003-01-30 == + +* Don't include execinfo.h in os_dep.c when it's not needed, and may not +exist. + + +== [6.2alpha2] == + +* Fixed the completely broken FreeBSD code in 6.2alpha1 (thanks to +Hironori Sakamoto for the patch). +* Changed IRIX reference in dbg_mlc.c to IRIX5 (thanks to Marcus Herbert). +* Attempted to work around the problems with .S filenames and the SGI +compiler. (Untested.) +* Worked around an HP/UX make issue with the GNU-style build process. +* Fixed the --enable-cplusplus build machinery to allow builds without +a C++ compiler. (That was always the intent ...) +* Changed the debugging allocation macros to explicitly pass the return +address for Linux and XXXBSD on hardware for which we can't get stack +traces. Use __builtin_return_address(0) to generate it when possible. +Some of the configuration work was cleaned up (good) and moved to gc.h +(bad, but necessary). This should make leak detection more useful +on a number of platforms. (Thanks to Fabian Thylman for the suggestion.) +* Fixed compilation problems in dbg_mlc.c with GC_ADD_CALLER. +* Bumped revision number for dynamic library. + + +== [6.2alpha1] 2003-01-23 == + +* Guard the test for GC_DUMP_REGULARLY in misc.c with +"#ifndef NO_DEBUGGING". Otherwise it fails to build with NO_DEBUGGING +defined. (Thanks to Manuel Serrano.) +* Message about retrying suspend signals was incorrectly generated even when +flag was not set. +* Cleaned up MACOSX/NEXT root registration code. There was apparently a +separate ifdef case in GC_register_data_segments() for no reason. +* Removed MPROTECT_VDB for MACOSX port, based on one negative report. +* Arrange for gc.h and friends to be correctly installed with GNU-style +"make install". +* Enable the GNU-style build facility include C++ support in the library +with --enable-cplusplus (thanks to Thomas Maier for some of the patch). +* Mark from GC_thread_key in linux_threads.c, in case that's allocated +from the garbage collected heap, as it is with our own thread-specific +storage implementation (thanks to Jeff Sturm). +* Mark all free list header blocks if they are heap allocated. This avoids +some unnecessary tracing. And it remains correct if we clear the +root set. (Thanks to Jeff Sturm for identifying the bug.) +* Improved S390/Linux support. Add S390/Linux 64-bit support (thanks to +Ulrich Weigand). +* Corrected the spelling of GC_{M,C}ALLOC_EXPLICTLY_TYPED to +GC_{M,C}ALLOC_EXPLICITLY_TYPED in gc_typed.h. This is technically +an interface change. Based on the fact that nobody reported this, +I suspect/hope there were no clients. +* Cleaned up gc_typed.h so that (1) it adds an extern "C" declaration +when appropriate, (2) doesn't generate references to undefined internal +macros, and (3) allows easier manual construction of descriptors. +* Close the file descriptor used by GC_print_address_map(). +* Set the "close-on-exec" bit for various file descriptors maintained +for the collector's internal use. +* Added a hack to find memory segments owned by the system allocator +under win32. Based on my tests, this tends to eventually find all +segments, though it may take a while. There appear to be cleaner, +but slower solutions under NT/XP. But they rely on an API that's +unsupported under 9X. +* Changed Linux PowerPC stack finding to LINUX_STACKBOTTOM. (Thanks +to Akira Tagoh for pointing out that HEURISTIC1 does not work on +64-bit kernels.) +* Added GC_set_free_space_divisor to avoid some Windows dll issues. +* Added FIXUP_POINTER, POINTER_SHIFT, POINTER_MASK to allow preprocessing +of candidate pointers for tagging, etc. +* Always lock around GC_notify_full_gc(). Simplified code for +invoking GC_notify_full_gc(). +* Changed the way DATASTART is defined on FreeBSD to be robust against +an unmapped page after etext. (Thanks to Hironori Sakamoto for +tracking down the intermittent failure.) +* Made GC_enable() and GC_disable() official. Deprecated direct update +of GC_dont_gc. Changed GC_gcollect to be a noop when garbage collection +is disabled. +* Call GC_register_dynamic_libraries before stopping the world on Linux, +in order to avoid a potential deadlock due to the dl_iterate_phdr lock. +* Introduced a more general mechanism for platform-dependent code to +decide whether the main data segment should be handled separately +from dynamic libraries, or registered by GC_register_dynamic_libraries. +The latter is more reliable and easier on Linux with dl_iterate_phdr. + + +== [6.1] == + +* Added GC_MAXIMUM_HEAP_SIZE environment variable. +* Fix configure.in for MIPS/LINUX (thanks to H.J. Lu). +* Double page hash table size for -DLARGE_CONFIG. +* Integrated Bo Thorsen's x64 support. +* STACKBOTTOM definition for LINUX/MIPS was partially changed back +(thanks to H.J. Lu and Hiroshi Kawashima for resolving this). +* Replaced all occurrences of LINUX_DATA_START in gcconfig.h with +SEARCH_FOR_DATA_START. It doesn't hurt to fall back to a search. +And __data_start doesn't seem to get defined correctly of the GC +library is loaded with LD_PRELOAD, e.g. for leak detection. +* If the GC_find_leak environment variable is set, do a +atexit(GC_gcollect) to give us at least one chance to detect leaks. +This may report some very benign leaks, but ... +* Addeded REDIRECT_FREE. It's necessary if we want leak detection with +LD_PRELOAD. +* Defer printing of leaked objects, as for smashed objects. +* Fixed process and descriptor leak in GC_print_callers. Try for +line number even if we got function name.) +* Ported parallel GC support and thread local allocation to Alpha. +Not yet well-tested. +* Added GC_DUMP_REGULARLY and added finalization statistics to GC_dump(). +* Fixed Makefile.am to mention alpha_mach_dep.S instead of the defunct +alpha_mach_dep.s. +* Incorporated a change to new_gc_alloc.h, +which should make it work with gcc3.1. +* Use alpha_mach_dep.S only on Linux. (It's not clear that this is +optimal, but it otherwise didn't build on Tru64. Thanks to Fergus Henderson.) +* Added ifdef to guard free() in os_dep.c. Otherwise we get a +compilation error on Irix (thanks to Dai Sato). +* Added an experimental version of GC_memalign to mallocx.c. This can't +always work, since we don't handle alignment requests in the hblk-level +allocator, and we can't handle arbitrary pointer displacements unless +GC_all_interior_pointers is enabled. But it should work for alignment +requests up to HBLKSIZE. This is not yet documented in the standard +places. +* Finally debugged the OSF1/Tru64 thread support. This needs more testing, +since I needed to add a somewhat unconvincing workaround for signal +delivery issues that I don't yet completely understand. But it does +pass my tests, even in parallel GC mode. Incremental GC support is +disabled if thread support is enabled, due to the signal issues. +* Eliminated name-space-incorrect definition of _cdecl from gc_cpp.h. +* Added GC_debug_malloc_replacement and GC_debug_realloc_replacement +declarations to gc.h. On IA64, this is required for REDIRECT_MALLOC +to work correctly with these. +* Fixed Linux USE_PROC_FOR_LIBRARIES to work with a 64-bit /proc format. + + +== [6.1alpha5] 2002-06-19 == + +* Added GC_finalizer_mem_freed, and changed some of the code that +decided on heap expansion to look at it. Memory explicitly +deallocated by finalizers essentially needs to be counted as reclaimed +by the GC. Otherwise there are cases in which the heap can grow +infinitely. (Thanks to Mark Reichert for the test case.) +* Integrated Adam Megacz patches to not scan dynamic libraries if +we are compiling with gcc on win32. Otherwise we need structured +exception handling to deal with asynchronously unmapped root +segments, and gcc doesn't directly support that. +* Integrated Anthony Green's patch to support Wine. +* GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several +places, including gc_cpp.cc (thanks to Wink Saville for pointing this out). +* Integrated Loren J. Rittle's Alpha FreeBSD patches. These also +changed the declarations of symbols like _end on many platforms to +that they wouldn't mistakenly be declared as short data symbols (suggested by +Richard Henderson). +* Integrated changes from the Debian distribution (thanks to Ryan Murray +for pointing these out). +Fix C++ comments in POWERPC port. Add ARM32 +incremental GC support. Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux, +this time for real. Use va_copy to get rid of cord printf problems +(finally). +* Close file descriptor used to count CPUs (thanks to Jeff Sturm for +pointing out the omission). +* Don't just drop gcj free lists in GC_start_reclaim, since that can +eventually cause the marker to see a bogus mark descriptor in the +dropped objects. The usual symptom was a very intermittent segmentation +fault in the marker. This mattered only if one of the GC_gcj_malloc +variants was used (thanks to Michael Smith, Jeff Sturm, Bryce McKinlay and +Tom Tromey for helping to track this down). +* Fixed Linux and Solaris/64 SPARC configuration (thanks to David Miller, +Jeff Sturm, Tom Tromey, and Christian Joensson). +* Fixed a typo in strdup definition (thanks to Gerard A Allan). +* Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S. +This is needed on Linux. I'm not sure whether it's better or worse +on Tru64. +* Changed gc_cpp.h once more to declare operator new and friends only in +a Microsoft environment. This may need further fine tuning (thanks to +Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4). +* Don't ever override strdup if it's already macro defined (thanks to +Adnan Ali for pointing out the problem). +* Changed gc_cpp.h yet again to also overload placement new. Due to the +C++ overloading rules, the other overloaded new operations otherwise hide +placement new, which causes many STL uses to break (thanks to Reza Shahidi +for reporting this, and to Matt Austern for proposing a fix). +* Integrated cygwin pthreads support from Dan Bonachea. +* Turn on DYNAMIC_LOADING for NetBSD (thanks to Krister Walfridsson). +* Changed printing code to print more complete GC times. +* Applied Mark Mitchell's Irix patch to correct some bit rot. +* Clarified which object-printing routines in dbg_mlc.c should hold +the allocation lock. Restructured the code to allow reasonable object +printing with -DREDIRECT_MALLOC. +* Fix the Linux mmap code to always start with 0x1000 as the initial hint. +Minor patches for 64-bit AIX, particularly to STACKBOTTOM (thanks to +Jeffrey Mark Siskind). +* Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict +with a system header (thanks to Philip Brown). +* Cause win32_threads.c to handle an out of range stack pointer correctly, +though currently with a warning. (Thanks to Jonathan Clark for +observing that Windows applications may temporarily use the stack +pointer for other purposes, and suggesting a fix. Unfortunately, it's +not clear that there is a complete solution to this problem.) + + +== [6.1alpha4] 2002-06-16 == + +* Fixed typo in sparc_mach_dep.S, preventing the 64-bit version from +building. Increased 64-bit heap size limit in test.c slightly, since +a functional SPARC collector seems to slightly exceed the old limits. +* Use NPRGREG in solaris_threads.c, thus printing all registers if things +go wrong. +* Added GC_MARKERS environment variable to allow use of a single marker +thread on an MP without confusing the lock implementation. +* Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED. +This is really a purely generational mode, and we can afford to +postpone the collection until the heap is (nearly) full. +* Remove read() wrapper for MPROTECT_VDB. It was causing more harm than +good. It is often no longer needed if system calls avoid writing to +pointerful heap objects. +* Fix MACOSX test in gcconfig.h (thanks to John Clements). +* Change GC_test_and_set so that it consistently has one argument. +Add spaces to ::: in powerpc assembly code in gc_locks.h (thanks to +Ryan Murray). +* Fixed a formatting error in dbg_mlc.c. Added prototype to GC_abort() +declaration (thanks to Michael Smith). +* Removed "source" argument to GC_find_start(). Eliminate GC_FIND_START(). +* Added win32 recognition code in configure.in. Changed some of the +dllimport/export defines in gc.h (thanks to Adam Megacz). +* GC_malloc_many didn't set hb_last_reclaimed when it called +GC_reclaim_generic. (I'm not sure this matters much, but ...) +* Allocating uncollectible objects with debug information sometimes +allocated objects that were one byte too small, since uncollectible +objects don't have the extra byte added at the end (thanks to +Wink Saville for pointing this out). +* Added a bit more assertion checking to make sure that gcj objects +on free lists never have a nonzero second word. +* Replaced BCC_MAKEFILE with an up-to-date one (thanks to Andre Leiradella). +* Upgraded libtool, configure.in and some related files to hopefully +support NetBSD/SPARC (thanks to Adrian Bunk). Unfortunately, +libtool 1.4.2 seemed to be buggy due to missing quotes in several +"test" invocations. Fixed those in the ltmain.sh script. +* Some win32-specific patches, including the introduction of +GC_CreateThread (thanks to Adam Megacz). +* Merged in gcj changes from Anthony Green to support embedded systems. +* Tried to consistently rename preprocessed assembly files with a capital +.S extension. +* Use alpha_mach_dep.S on ALPHA again. It doesn't really matter, but this +makes our distribution consistent with the gcc one, avoiding future merge +problems. +* Move GET_MEM definition into gcconfig.h. Include gcconfig.h slightly +later in gc_priv.h to avoid forward references to ptr_t. +* Add some testing of local allocation to test.c. +* Change definition of INVALID_QTID in specific.h. The -1 value was used +inconsistently, and too likely to collide with a valid stack address. +Some general clean-up of specific.[ch]. Added assertions. (Thanks +to Michael Smith for tracking down an intermittent bug to this +general area. I'm not sure it has been squashed yet, however.) +* On Pthread systems it was not safe to call GC_malloc() between fork() +and exec(). According to the applicable standards, it doesn't appear +to be safe to call malloc() or many other libc functions either, thus +it's not clear this is fixable. Added experimental support for +-DHANDLE_FORK in linux_threads.c which tries to support it. It may +succeed if libc does the right thing. I'm not sure whether it does. +(Thanks to Kenneth Schalk for pointing out this issue.) +* Documented thread local allocation primitives to require an +explicit GC_init call. GC_init_parallel is no longer declared to +be a constructor function, since that isn't portable and often +seems to lead to initialization order problems. +* Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them +compatible with Visual C++ 6 (thanks to Wink Saville for the patch). +* Some more patches for Linux on HP PA-RISC. +* Added include/gc_allocator.h. It implements (hopefully) standard +conforming (as opposed to SGI-style) allocators that allocate +collectible (gc_allocator) or GC-traceable, but not collectible +(traceable_allocator) objects. This borrows heavily from libstc++, +which borrows heavily from the SGI implementation, this part of +which was written by Matt Austern. Changed test_cpp.cc to very +minimally test this. +* On Linux/x86, retry mmap with a different start argument. That should +allow the collector to use more (closer to 3GB) of the address space. +* Force 64 bit alignment with GCJ support (reflects Bryce McKinlay's +patch to the gcc tree). +* Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init +to accommodate some glibc5 systems (thanks to Dan Fandrich for the patch). +* Compensated for the fact that current versions of glibc set +__libc_stack_end incorrectly on Linux/IA64 while initialization code +is running. This could cause the collector to miss 16 bytes of +the memory stack if GC_malloc or friends where called before main(). +* Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86. +This will probably take another iteration to work, since his +patch conflicted with the libtool upgrade. +* Added README.arm.cross containing some information about cross- +compiling to an ARM processor from Margaret Fleck (original code provided by +Bradley D. LaRonde; edited by Andrej Cedilnik using some of solutions by +Tilman Vogel; also ported for iPAQ by Oliver Kurth). + + +== [6.1alpha3] 2002-02-07 == + +* Minor cleanup on the gcconfig.h section for SPARC. +* Minor fix to support Intel compiler for Linux/x86 (thanks to +Sven Hartrumpf). +* Added SPARC V9 (64-bit) support (thanks to Jeff Sturm). +* Restructured the way in which we determine whether or not to keep +call stacks for debug allocation. By default SAVE_CALL_COUNT is +now zero on all platforms. Added SAVE_CALL_NARGS parameters. +If possible, use execinfo.h to capture call stack. (This should +add support for a number of new platforms, though often at +considerable runtime expense.) +* Try to print symbolic information for call stacks. On Linux, we +do this with a combination of execinfo.h and running addr2line in +a separate process. This is both much more expensive and much more +useful. Amazingly, it seems to be fast enough for most purposes. +* Redefined strdup if -DREDIRECT_MALLOC is given. +* Changed incremental collector and MPROTECT_VDB implementation so that, +under favorable conditions, pointer-free objects are not protected. +Added GC_incremental_protection_needs() to determine ahead of time whether +pointer-free objects may be protected. Replaced GC_write_hint() with +GC_remove_protection(). +* Added test for GC_ENABLE_INCREMENTAL environment variable. +* Made GC_time_limit runtime configurable. Added GC_PAUSE_TIME_TARGET +environment variable. +* Eliminated GC_page_sz, a duplicate of GC_page_size. +* Caused the Solaris and Irix thread creation primitives to call +GC_init_inner(). + + +== [6.1alpha2] 2001-12-20 == + +* No longer wrap read by default in multi-threaded applications. It was +pointed out on the libgcj list that this holds the allocation lock for +way too long if the read blocks. For now, reads into the heap are +broken with incremental collection. It's possible to turn this back on +if you make sure that read calls don't block (e.g. by calling select +first). +* Fix ifdef in Solaris_threads.h to refer to GC_SOLARIS_THREADS. +* Added check for environment variable GC_IGNORE_GCJ_INFO. +* Added printing of stop-the-world GC times if GC_PRINT_STATS environment +variable is set. +* The calloc definition in leak_detector.h was missing parentheses, and +realloc was missing a second argument to GC_REALLOC (thanks to +Elvenlord Elrond). +* Added GC_PRINT_BACK_HEIGHT environment variable and associated +code, mostly in the new file backgraph.c. See doc/README.environment. +* Added -DUSE_GLOBAL_ALLOC to work around a Windows NT issue (thanks to +Jonathan Clark). +* Integrated port to NEC EWS4800 (MIPS-based workstation, with somewhat +different address-space layout). This may help for other machines with +holes in the data segment. (Thanks to Hironori Sakamoto.) +* Changed the order in which GC_push_roots and friends push things onto +the mark stack. GC_push_all calls need to come first, since we can't +necessarily recover if those overflow the mark stack. (Thanks to +Matthew Flatt for tracking down the problem.) +* Some minor cleanups to mostly support the Intel compiler on Linux/IA64. + + +== [6.1alpha1] 2001-09-22 == + +* Non-debug, atomic allocations could result in bogus smashed object +reports with debugging on (thanks to Patrick Doyle for the small test case). +* Fixed GC_get_register_stack_base (Itanium only) to work around a glibc +2.2.4 bug. +* Initial port to HP/UX on Itanium. Thread support and both 32 and 64 +bit ABIs appear to work. Parallel mark support doesn't yet, due to +some inline assembly code issues. Thread local allocation does appear +to work. +* ifdef'ed out glibc2.1/Itanium workaround. I suspect nobody is using +that combination anymore. +* Added a patch to make new_gc_alloc.h usable with gcc3.0 (thanks to +Dimitris Vyzovitis for the patch). +* Debugged 64-bit support on HP/UX PA-RISC. +* Turned on dynamic loading support for FreeBSD/ELF (thanks to Peter Housel). +* Unregistering of finalizers with debugging allocation was broken (thanks +to Jani Kajala for the test case). +* Old finalizers were not returned correctly from GC_debug_register_finalizer. +* Disabled MPROTECT_VDB for Linux/M68K based on a report that it doesn't work. +* Cleaned up some statistics gathering code in reclaim.c (thanks to +Walter Bright). +* Added some support for OpenBSD/ELF/Linux (thanks to Suzuki Toshiya). +* Added Jakub Jelinek's patch to use dl_iterate_phdr for dynamic library +traversal to dyn_load.c. Changed it to weakly reference dl_iterate_phdr, +so that the old code is still used with old versions of glibc. +* Cleaned up feature test macros for various threads packages and +integrated (partially functional) FreeBSD threads code from Loren J. Rittle. +It's likely that the cleanup broke something, since it touched lots of +code. It's also likely that it fixed some unreported bugs in the +less common thread implementations, since some of the original code +didn't stand up to close scrutiny. Support for the next pthreads +implementation should be easier to add. + + +== [6.0] 2001-07-26 == + +* Two more bug fixes for KEEP_BACK_PTRS and DBG_HDRS_ALL. +* Fixed a stack clearing problem that resulted in SIGILL with a +misaligned stack pointer for multi-threaded SPARC builds. +* Integrated another HURD patch (thanks to Igor Khavkine). + + +== [6.0alpha9] == + +* added README.macros. +* Made gc.mak a symbolic link to work around winzip's tendency to ignore +hard links. +* Simplified the setting of NEED_FIND_LIMIT in os_dep.c, possibly breaking +it on untested platforms. +* Integrated initial GNU HURD port (thanks to Chris Lingard and +Igor Khavkine). +* A few more fixes for Digital Mars compiler (by Walter Bright). +* Fixed gcc version recognition. Renamed OPERATOR_NEW_ARRAY to +GC_OPERATOR_NEW_ARRAY. Changed GC_OPERATOR_NEW_ARRAY to be the default. +It can be overridden with -DGC_NO_OPERATOR_NEW_ARRAY (thanks to +Cesar Eduardo Barros). +* Changed the byte size to free-list mapping in thread local allocation +so that size 0 allocations are handled correctly. +* Fixed Linux/MIPS stackbottom for new toolchain (thanks to Ryan Murray). +* Changed finalization registration to invoke GC_oom_fn when it runs out +of memory. +* Removed lvalue cast in finalize.c. This caused some debug configurations +not to build with some non-gcc compilers. + + +== [6.0alpha8] 2001-06-15 == + +* Changed GC_debug_malloc_replacement and GC_debug_realloc_replacement +so that they compile under Irix (thanks to Dave Love). +* Updated powerpc_macosx_mach_dep.s so that it works if the collector +is in a dynamic library (thanks to Andrew Begel). +* Transformed README.debugging into debugging.html, updating and +expanding it in the process. Added gcdescr.html and tree.html +from the web site to the GC distribution. +* Fixed several problems related to PRINT_BLACK_LIST. This involved +restructuring some of the marker macros. +* Fixed some problems with the sizing of objects with debug information. +Finalization was broken KEEP_BACK_PTRS or PRINT_BLACK_LIST. Reduced the +object size with SHORT_DEBUG_HDRS by another word. +* The "Needed to allocate blacklisted ..." warning had inadvertently +been turned off by default, due to a buggy test in allchblk.c. Turned +it back on. +* Removed the marker macros to deal with 2 pointers in interleaved fashion. +They were messy and the performance improvement seemed minimal. We'll +leave such scheduling issues to the compiler. +* Changed Linux/PowerPC test to also check for __powerpc__ in response +to a discussion on the gcc mailing list. +* Removed the "static" from the jmp_buf declaration in GC_generic_push_regs +(suggested by Matthew Flatt). This was causing problems in +systems that register all of their own roots. It looks far more correct +to me without the "static" anyway. +* Fixed several problems with thread local allocation of pointer-free or +typed objects. The collector was reclaiming thread-local free lists, since +it wasn't following the link fields. +* There was apparently a long-standing race condition related to +multi-threaded incremental collection. A collection could be started and +a thread stopped between the memory unprotect system call and the setting of +the corresponding dirt bit. I believe this did not affect Solaris or PCR, +which use a different dirty-bit implementation. Fixed this by installing +signal handlers with sigaction instead of signal, and disabling the thread +suspend signal while in the write-protect handler. (It is unclear +whether this scenario ever actually occurred.) +* Incremental collection did not cooperate correctly with the PARALLEL_MARK +implementation of GC_malloc_many or the local_malloc primitives. It still +doesn't work well, but it shouldn't lose memory anymore. +* Integrated some changes from the gcc source tree that I had previously +missed (thanks to Bryce McKinlay for the reminder and patch). +* Added Makefile.direct as a copy of the default Makefile, which would +normally be overwritten if configure is run. +* Changed the gc.tar target in Makefile.direct to embed the version number +in the gc directory name. This will affect future tar file distributions. +* Changed the Irix dynamic library finding code to no longer try to +eliminate writable text segments under Irix6.x, since that is probably no +longer necessary, and can apparently be unsafe on occasion (thanks to +Shiro Kawai for pointing this out). +* GC_cleanup with GC_DEBUG enabled passed a real object base address to +GC_debug_register_finalizer_ignore_self, which expected a pointer past the +debug header. Call GC_register_finalizer_ignore_self instead, even with +debugging enabled (thanks to Jean-Daniel Fekete for catching this). +* The collector didn't build with call chain saving enabled but NARGS=0. +* Fixed up the GNU-style build files enough so that they work in some +obvious cases (thanks to Maarten Thibaut). +* Added initial port to Digital Mars compiler for win32 (thanks to Walter +Bright). + + +== [6.0alpha7] 2001-04-19 == + +* Added GC_finalizer_notifier. Fixed GC_finalize_on_demand. (The variable +actually wasn't being tested at the right points. The build-time flag +was.) +* Added Tom Tromey's S390 Linux patch. +* Added code to push GC_finalize_now in GC_push_finalizer_structures +(thanks to Matthew Flatt). +* Added GC_push_gc_structures() to push all GC internal roots. +* Integrated some FreeBSD changes from Matthew Flatt. +* It looks like USRSTACK is not always correctly defined under Solaris. +Hacked gcconfig.h to attempt to work around the problem. The result +is not well tested. (Thanks again to Matthew Flatt for pointing this out.) +* Added Ji-Yong Chung's win32 threads and C++ fixes. +* Arranged for hpux_test_and_clear.s to no longer be needed or built. +It was causing build problems with gas, and it's not clear this is +better than the pthreads alternative on this platform. +* Some MINGW32 fixes from Hubert Garavel. +* Added initial Hitachi SH4 port from Kaz Kojima. +* Ported thread-local allocation and parallel mark code to HP/UX on PA_RISC. +* Made include/gc_mark.h more public and separated out the really private +pieces. This is probably still not quite sufficient for clients that +want to supply their own kind of type information. But it's a start. +This involved lots of identifier renaming to make it namespace clean. +* Added GC_dont_precollect for clients that need complete control over +the root set. +* GC_is_visible didn't do the right thing with gcj objects. (Not that +many people are likely to care, but ...) +* Don't redefine read with GC_USE_LD_WRAP. +* Initial port to LINUX/HP_PA. Incremental collection and threads are not +yet supported. (Incremental collection should work if you have the +right kernel. Threads may work with a sufficiently patched pthread +library.) +* Changed gcconfig.h to recognize __i386__ as an alternative to x86 in +many places (thanks to Benjamin Lerman). +* Made win32_threads.c more tolerant of detaching a thread that it didn't +know about (thanks to Paul Nash). +* Added Makefile.am and configure.in from gcc to the distribution, with +minimal changes. For the moment, those are just placeholders. In the +future, we're planning to switch to a GNU-style build environment for +Un*x-like systems, though the old Makefile will remain as a backup. +* Turned off STUBBORN_ALLOC by default, and added it back as a Makefile +option. +* Redistributed some functions between malloc.c and mallocx.c, so that +simple statically linked apps no longer pull in mallocx.o. +* Changed large object allocation to clear the first and last few words +of each block before releasing the lock. Otherwise the marker could see +objects with nonsensical type descriptors. +* Fixed a couple of subtle problems that could result in not recognizing +interior pointers from the stack. (I believe these were introduced +in 6.0alpha6.) +* GC_debug_free_inner called GC_free, which tried to reacquire the +allocator lock, and hence deadlocked. (DBG_HDRS_ALL probably never worked +with threads.) +* Fixed several problems with back traces. Accidental references to a free +list could cause the free list pointer to be overwritten by a back pointer. +There seemed to be some problems with the encoding of root and finalizer +references. + + +== [6.0alpha6] == + +* Changed the definition of DATASTART on ALPHA and IA64, where data_start +and __data_start are not defined by earlier versions of glibc. This might +need to be fixed on other platforms as well. +* Changed the way the stack base and backing store base are found on IA64. +This should now remain reliable on future kernels. But since it relies +on /proc, it will no longer work in the simulated NUE environment. +* Made the call to random() in dbg_mlc.c with -DKEEP_BACK_PTRS dependent +on the OS. On non-Unix systems, rand() should be used instead. Handled +small RAND_MAX (thanks to Peter Ross for pointing this out). +* Fixed the cord make rules to create the cord subdirectory, if necessary +(thanks to Doug Moen). +* Changed fo_object_size calculation in finalize.c. Turned finalization +of non-heap object into a no-op. Removed anachronism from GC_size() +implementation. +* Changed GC_push_dirty call in solaris_threads.c to GC_push_selected. +It was missed in a previous renaming (thanks to Vladimir Tsichevski +for pointing this out). +* Arranged to not mask SIGABRT in linux_threads.c (thanks to Bryce McKinlay). +* Added GC_no_dls hook for applications that want to register their own +roots. +* Integrated Kjetil Matheussen's Amiga changes. +* Added FREEBSD_STACKBOTTOM. Changed the FreeBSD/x86 port to use it +(thanks to Matthew Flatt). +* Added pthread_detach interception for platforms supported by linux_threads.c +and irix_threads.c. +* Changed the USE_MMAP code to check for the case in which we got the +high end of the address space, i.e. mem_ptr + mem_sz == 0. It appears +that this can happen under Solaris 7. It seems to be allowed by what +I would claim is an oversight in the mmap specification. (Thanks to +Toshio Endo for pointing out the problem.) +* Cleanup of linux_threads.c. Some code was originally cloned from +irix_threads.c and now unnecessary. Some comments were obviously wrong. +* (Mostly) fixed a longstanding problem with setting of dirty bits from +a signal handler. In the presence of threads, dirty bits could get lost, +since the getting of a bit in the bit vector was not atomic with respect +to other updates. The fix is 100% correct only for platforms for which +GC_test_and_set is defined. The goal is to make that all platforms with +thread support. Matters only if incremental GC and threads are both +enabled. +* made GC_all_interior_pointers (a.k.a. ALL_INTERIOR_POINTERS) an +initialization time, instead of build-time option. This is a +nontrivial, high risk change. It should slow down the code measurably +only if MERGE_SIZES is not defined, which is a very nonstandard +configuration. +* Added doc/README.environment, and implemented what it describes. This +allows a number of additional configuration options to be set through +the environment. It documents a few previously undocumented options. +* Integrated Eric Benson's leak testing improvements. +* Removed the option to throw away the beginning of each page (DISCARD_WORDS). +This became less and less useful as processors enforce stricter alignment. +And it hadn't been tested in ages, and was thus probably broken anyway. + + +== [6.0alpha5] == + +* Changed the definition of GC_pause in linux_threads.c to use a volatile +asm. Some versions of gcc apparently optimize away writes to local volatile +variables. This caused poor locking behavior starting at about +4 processors. +* Added GC_start_blocking(), GC_end_blocking() calls and wrapper for sleep +to linux_threads.c. +The first two calls could be used to generally avoid sending GC signals to +blocked threads, avoiding both premature wakeups and unnecessary overhead. +* Fixed a serious bug in thread-local allocation. At thread termination, +GC_free could get called on small integers. Changed the code for thread +termination to more efficiently return left-over free-lists. +* Integrated Kjetil Matheussen's BeOS support. +* Rearranged the directory structure to create the doc and tests +subdirectories. +* Sort of integrated Eric Benson's patch for OSF1. This provided basic +OSF1 thread support by suitably extending hpux_irix_threads.c. Based +on earlier email conversations with David Butenhof, I suspect that it +will be more reliable in the long run to base this on linux_threads.c +instead. Thus I attempted to patch up linux_threads.c based on Eric's code. +The result is almost certainly broken, but hopefully close enough that +someone with access to a machine can pick it up. +* Integrated lots of minor changes from the NetBSD distribution. (These +were supplied by David Brownlee. I'm not sure about the original +authors.) +* Hacked a bit more on the HP/UX thread-support in linux_threads.c. It +now appears to work in the absence of incremental collection. Renamed +hpux_irix_threads.c back to irix_threads.c, and removed the attempt to +support HPUX there. +* Changed gc.h to define _REENTRANT in cases in which it should already +have been defined. It is still safer to also define it on the command +line. + + +== [6.0alpha4] == + +* Moved up the detection of mostly full blocks to the initiation of the +sweep phase. This eliminates some lock contention in the PARALLEL_MARK case, +as multiple threads try to look at mostly full blocks concurrently. +* Restored the code in GC_malloc_many that grabs a prefix of the global +free list. This avoids the case in which every GC_malloc_many call +tries and fails to allocate a new heap block, and the returns a single +object from the global free list. +* Some minor fixes in new_hblk.c. (Attempted to build free lists in order +of increasing addresses instead of decreasing addresses for cache performance +reasons. But this seems to be only a very minor gain with -DEAGER_SWEEP, +and a loss in other cases. So the change was backed out.) +* Fixed some of the documentation (thanks in large part to Fergus Henderson). +* Fixed the Linux USE_PROC_FOR_LIBRARIES code to deal with apps that perform +large numbers of mmaps (thanks to Eric Benson). Also fixed that code to +deal with short reads. +* Added GC_get_total_bytes(). +* Fixed leak detection mode to avoid spurious messages under linuxthreads. +(This should also now be easy for the other supported threads packages. +But the code is tricky enough that I'm hesitant to do it without being able +to test. Everything allocated in the GC thread support itself should be +explicitly deallocated.) +* Made it possible (with luck) to redirect malloc to GC_local_malloc. + + +== [6.0alpha3] 2000-09-26 == + +* Fixed the /proc/self/maps code to not seek, since that apparently is not +reliable across all interesting kernels. +* Fixed some compilation problems in the absence of PARALLEL_MARK +(introduced in alpha2). +* Fixed an algorithmic problem with PARALLEL_MARK. If work needs to +be given back to the main mark "stack", the BOTTOM entries of the local +stack should be given away, not the top ones. This has substantial +performance impact, especially for > 2 processors, from what I can tell. +* Extracted gc_lock.h from gc_priv.h. This should eventually make it a +bit easier to avoid including gc_priv.h in clients. +* Moved all include files to include/ and removed duplicate links to the +same file. The old scheme was a bad idea because it was too easy to get the +copies out of sync, and many systems don't support hard links. +Unfortunately, it's likely that I broke some of the non-Unix Makefiles in +the process, although I tried to update them appropriately. +* Removed the partial support for a copied nursery. It's not clear that +this would be a tremendous win, since we don't consistently lose to +generational copying collectors. And it would significantly complicate +many things. May be reintroduced if/when it really turns out to win. +* Removed references to IRIX_JDK_THREADS, since I believe there never +were and never will be any clients. +* Added some code to linux_threads.c to possibly support HPUX threads +using the Linux code. Unfortunately, it doesn't work yet, and is +currently disabled. +* Added support under Linux/x86 for saving the call chain, both in (debug) +objects for client debugging, and in GC_arrays._last_stack for GC +debugging. This was previously supported only under Solaris. It is +not enabled by default under x86, since it requires that code be compiled +to explicitly gave frame pointers on the call stack. (With gcc this +currently happens by default, but is often turned off explicitly.) +To turn it on, define SAVE_CALL_CHAIN. + + +== [6.0alpha2] == + +* Added USE_MARK_BYTES to reduce the need for compare-and-swap on platforms +for which that's expensive. +* Fixed a locking bug ib GC_gcj_malloc and some locking assertion problems. +* Added a missing volatile to OR_WORD and renamed the parameter to +GC_compare_and_swap so it's not a C++ reserved word (thanks to +Toshio Endo for pointing out both of those). +* Changed Linux dynamic library registration code to look at /proc/self/maps +instead of the rld data structures when REDIRECT_MALLOC is defined. +Otherwise some of the rld data data structures may be prematurely garbage +collected. +* Fixed USE_LD_WRAP a bit more, so it should now work without threads. +* Renamed XXX_THREADS macros to GC_XXX_THREADS for namespace correctness. +Temporarily added some backward compatibility definitions. Renamed +USE_LD_WRAP to GC_USE_LD_WRAP. +* Many MACOSX POWERPC changes, some additions to the gctest output, and +a few minor generic bug fixes (thanks to Dietmar Planitzer). + + +== [6.0alpha1] == + +* Added HP/PA prefetch support. +* Added -DDBG_HDRS_ALL and -DSHORT_DBG_HDRS to reduce the cost and improve +the reliability of generating pointer backtrace information, e.g. in +the Bigloo environment. +* Added parallel marking support (-DPARALLEL_MARK). This currently +works only under IA32 and IA64 Linux, but it shouldn't be hard to adapt +to other platforms. This is intended to be a lighter-weight (less +new code, probably not as scalable) solution than the work by Toshio Endo +et al, at the University of Tokyo. A number of their ideas were +reused, though the code wasn't, and the underlying data structure +is significantly different. In particular, we keep the global mark +stack as a single shared data structure, but most of the work is done +on smaller thread-local mark stacks. +* Changed GC_malloc_many to be cheaper, and to require less mutual exclusion +with -DPARALLEL_MARK. +* Added full support for thread local allocation under Linux +(-DTHREAD_LOCAL_ALLOC). This is a thin veneer on GC_malloc_many, and +should be easily portable to other platforms, especially those that +support pthreads. +* CLEAR_DOUBLE was not always getting invoked when it should have been. +* GC_gcj_malloc and friends used different out of memory handling than +everything else, probably because I forgot about one when I implemented +the other. They now both call GC_oom_fn(), not GC_oom_action(). +* Integrated Jakub Jelinek's fixes for Linux/SPARC. +* Moved GC_objfreelist, GC_aobjfreelist, and GC_words_allocd out of +GC_arrays, and separately registered the first two as excluded roots. +This makes code compiled with gc_inl.h less dependent on the +collector version. (It would be nice to remove the inclusion of +gc_priv.h by gc_inl.h completely, but we're not there yet. The +locking definitions in gc_priv.h are still referenced.) +This change was later conditioned on SEPARATE_GLOBALS, which +is not defined by default, since it involves a performance hit. +* Register GC_obj_kinds separately as an excluded root region. The +attempt to register it with GC_arrays was usually failing. (This wasn't +serious, but seemed to generate some confusion.) +* Moved backptr.h to gc_backptr.h. + + +== [5.4] == + +* Fixed a typo that prevented compilation with -DUSE_3DNOW_PREFETCH (thanks to +Shawn Wagner for actually testing this). +* Fixed GC_is_thread_stack in solaris_threads.c. It forgot to return a value +in the common case. +* Fixed another silly syntax problem in GC_double_descr (thanks to +Fergus Henderson for finding it). +* Fixed a GC_gcj_malloc bug: It tended to release the allocator lock twice. + + +== [5.3] 2000-09-24 == + +* Fixed _end declaration for OSF1. +* There were lots of spurious leak reports in leak detection mode, caused +by the fact that some pages were not being swept, and hence unmarked +objects weren't making it onto free lists. (This bug dated back to 5.0.) +* Fixed a typo in the liblinuxgc.so Makefile rule. +* Added the GetExitCodeThread to Win32 GC_stop_world to (mostly) work +around a Windows 95 GetOpenFileName problem (thanks to Jacob Navia). + + +== [5.2] == + +* dyn_load.c declared GC_scratch_last_end_ptr as an extern even if it +was defined as a macro. This prevented the collector from building on +Irix. +* We quietly assumed that indirect mark descriptors were never 0. +Our own typed allocation interface violated that. This could result +in segmentation faults in the marker with typed allocation. +* Fixed a _DUSE_MUNMAP bug in the heap block allocation code (thanks to +Ben Hutchings for the patch). +* Taught the collector about VC++ handling array operator new (thanks to +Ben Hutchings for the patch). +* The two copies of gc_hdrs.h had diverged. Made one a link to the other +again. + + +== [5.1] == + +* Fixed a gc.h header bug which showed up under Irix (thanks to Dan Sullivan). +* Fixed a typo in GC_double_descr in typd_mlc.c. +This probably could result in objects described by array descriptors not +getting traced correctly (thanks to Ben Hutchings for pointing this out). +* The block nearly full tests in reclaim.c were not correct for 64 bit +environments. This could result in unnecessary heap growth under unlikely +conditions. + + +== [5.0] == + +* Fixed threadlibs.c for linux threads. -DUSE_LD_WRAP was broken and +-ldl was omitted. Fixed Linux stack finding code to handle +-DUSE_LD_WRAP correctly. +* Added MSWIN32 exception handler around marker, so that the collector +can recover from root segments that are unmapped during the collection. +This caused occasional failures under Windows 98, and may also be +an issue under Windows NT/2000. + + +== [5.0alpha7] == + +* -DREDIRECT_MALLOC was broken in alpha6. Fixed. +* Cleaned up gc_ccp.h slightly, thus also causing the HP C++ compiler to +accept it. +* Removed accidental reference to dbg_mlc.c, which caused dbg_mlc.o to be +linked into every executable. +* Added PREFETCH to bitmap marker. Changed it to use the header cache. +* GC_push_marked sometimes pushed one object too many, resulting in a +segmentation fault in GC_mark_from_mark_stack. This was probably an old +bug. It finally showed up in gctest on win32. +* Gc_priv.h erroneously #defined GC_incremental to be TRUE instead of FALSE +when SMALL_CONFIG was defined. This was no doubt a major performance bug for +the default win32 configuration. +* Removed -DSMALL_CONFIG from NT_MAKEFILE. It seemed like an anachronism now +that the average PC has 64MB or so. +* Integrated Bryce McKinlay's patches for linux threads and dynamic loading +from the libgcj tree. Turned on dynamic loading support for Linux/PPC. +* Changed the stack finding code to use environ on HP/UX (thanks +to Gustavo Rodriguez-Rivera for the suggestion). This should +probably be done on other platforms, too. Since I can't test those, that'll +wait until after 5.0. + + +== [5.0alpha6] == + +* GC_malloc_explicitly_typed and friends sometimes failed to +initialize first word. +* Added allocation routines and support in the marker for mark descriptors +in a type structure referenced by the first word of an object. This was +introduced to support gcj, but hopefully in a way that makes it +generically useful. +* Added GC_requested_heapsize, and inhibited collections in non-incremental +mode if the actual used heap size is less than what was explicitly +requested. +* The Solaris pthreads version of GC_pthread_create didn't handle a NULL +attribute pointer. Solaris thread support used the wrong default thread +stack size (thanks to Melissa O'Neill for the patch). +* Changed PUSH_CONTENTS macro to no longer modify first parameter. +This usually doesn't matter, but it was certainly an accident waiting +to happen ... +* Added GC_register_finalizer_no_order and friends to gc.h. They're +needed by Java implementations. +* Integrated a fix for a win32 deadlock resulting from clock() calling +malloc (thanks to Chris Dodd). +* Integrated Hiroshi Kawashima's port to Linux/MIPS. This was designed +for a handheld platform, and may or may not be sufficient for other +machines. +* Fixed a va_arg problem with the %c specifier in cordprnt.c. It appears +that this was always broken, but recent versions of gcc are the first to +report the (statically detectable) bug. +* Added an attempt at a more general solution to dlopen races/deadlocks. +GC_dlopen now temporarily disables collection. Still not ideal, but ... +* Added -DUSE_I686_PREFETCH, -DUSE_3DNOW_PREFETCH, and support for IA64 +prefetch instructions. May improve performance measurably, but I'm not +sure the code will run correctly on processors that don't support the +instruction. Won't build except with very recent gcc. +* Added caching for header lookups in the marker. This seems to result +in a barely measurable performance gain. Added support for interleaved +lookups of two pointers, but unconfigured that since the performance +gain is currently near zero, and it adds to code size. +* Changed Linux DATASTART definition to check both data_start and +__data_start, since nothing else seems to be portable. +* Added -DUSE_LD_WRAP to optionally take advantage of the GNU ld function +wrapping mechanism. Probably currently useful only on Linux. +* Moved some variables for the scratch allocator into GC_arrays (suggested +by Martin Hirzel). +* Fixed a win32 threads bug that caused the collector to not look for +interior pointers from one of the thread stacks without +ALL_INTERIOR_POINTERS (thanks to Jeff Sturm). +* Added Mingw32 support (thanks to Jeff Sturm for the patch). +* Changed the alpha port to use the generic register scanning code instead +of alpha_mach_dep.s. Alpha_mach_dep.s doesn't look for pointers in fp +registers, but gcc sometimes spills pointers there (thanks to Manuel Serrano +for helping debug this). Changed the IA64 code to +do something similar for similar reasons. + + +== [5.0alpha4] 1999-10-30 == + +* Added protection fault handling patch for Linux/M68K from Fergus +Henderson and Roman Hodek. +* Removed the tests for SGI_SOURCE in new_gc_alloc.h. This was causing that +interface to fail on non-SGI platforms. +* Changed the Linux stack finding code to use /proc, after changing it +to use HEURISTIC1 (thanks to David Mosberger for pointing out /proc hook). +* Added HP/UX incremental GC support and HP/UX 11 thread support. +Thread support is currently still flaky. +* Added basic Linux/IA64 support. +* Integrated Anthony Green's PicoJava support. +* Integrated Scott Ananian's StrongARM/NetBSD support. +* Fixed some fairly serious performance bugs in the incremental +collector. These have probably been there essentially forever. +(Mark bits were sometimes set before scanning dirty pages. +The reclaim phase unnecessarily dirtied full small object pages.) +* Changed the reclaim phase to ignore nearly full pages to avoid +touching them. +* Limited GC_black_list_spacing to roughly the heap growth increment. +* Changed full collection triggering heuristic to decrease full GC +frequency by default, but to explicitly trigger full GCs during +heap growth. This doesn't always improve things, but on average it's +probably a win. +* GC_debug_free(0, ...) failed (thanks to Fergus Henderson for the +bug report and fix). + + +== [5.0alpha3] 1999-09-15 == + +(Also known as 4.15alpha3.) +* Added some highly incomplete code to support a copied young generation. +Comments on nursery.h are appreciated. +* Changed -DFIND_LEAK, -DJAVA_FINALIZATION, and -DFINALIZE_ON_DEMAND, +so the same effect could be obtained with a runtime switch. This is +a step towards standardizing on a single dynamic GC library. +* Significantly changed the way leak detection is handled, as a consequence +of the above. + + +== [5.0alpha2] 1999-07-23 == + +* Fixed bugs introduced in alpha1 (OpenBSD & large block initialization). +* Added -DKEEP_BACK_PTRS and backptr.h interface. (The implementation +idea came from Alan Demers.) + + +== [5.0alpha1] 1999-06-30 == + +(Also known as 4.15alpha1.) +* Reworked large block allocator. Now uses multiple doubly linked free +lists to approximate best fit. +* Changed heap expansion heuristic. Entirely free blocks are no longer +counted towards the heap size. This seems to have a major impact on +heap size stability; the old version could expand the heap way too +much in the presence of large block fragmentation. +* added -DGC_ASSERTIONS and some simple assertions inside the collector. +This is mainlyt for collector debugging. +* added -DUSE_MUNMAP to allow the heap to shrink. Supported on only +a few UNIX-like platforms for now. +* added GC_dump_regions() for debugging of fragmentation issues. +* Changed PowerPC pointer alignment under Linux to 4. +* Changed the Linux/Alpha port to walk the data segment backwards until +it encounters a SIGSEGV. The old way to find the start of the data +segment broke with a recent release. +* cordxtra.c needed to call GC_REGISTER_FINALIZER instead of +GC_register_finalizer, so that it would continue to work with GC_DEBUG. +* allochblk sometimes cleared the wrong block for debugging purposes +when it dropped blacklisted blocks. This could result in spurious +error reports with GC_DEBUG. +* added MACOS X Server support (thanks to Andrew Stone). +* Changed the Solaris threads code to ignore stack limits > 8 MB with +a warning. Empirically, it is not safe to access arbitrary pages +in such large stacks. And the dirty bit implementation does not +guarantee that none of them will be accessed. +* Integrated Martin Tauchmann's Amiga changes. +* Integrated James Dominy's OpenBSD/SPARC port. + + +== [4.14] 1999-04-16 == + +* changed STACKBOTTOM for DJGPP (thanks to Salvador Eduardo Tropea). + + +== [4.14alpha2] 1999-03-26 == + +* -DSMALL_CONFIG did not work reliably with large (> 4K) pages. +Recycling the mark stack during expansion could result in a size +zero heap segment, which confused things. (This was probably also an +issue with the normal config and huge pages.) +* Did more work to make sure that callee-save registers were scanned +completely, even with the setjmp-based code. Added USE_GENERIC_PUSH_REGS +macro to facilitate testing on machines I have access to. +* Added code to explicitly push register contents for win32 threads. +This seems to be necessary. (Thanks to Pierre de Rop.) + + +== [4.14alpha1] 1999-03-10 == + +* Fixed GC_print_source_ptr to not use a prototype. +* generalized CYGWIN test. +* gc::new did the wrong thing with PointerFreeGC placement (thanks to +Rauli Ruohonen). +* In the ALL_INTERIOR_POINTERS (default) case, some callee-save register +values could fail to be scanned if the register was saved and +reused in a GC frame. This showed up in verbose mode with gctest +compiled with an unreleased SGI compiler. I vaguely recall an old +bug report that may have been related. The bug was probably quite old. +(The problem was that the stack scanning could be deferred until +after the relevant frame was overwritten, and the new save location +might be outside the scanned area. Fixed by more eager stack scanning.) +* PRINT_BLACK_LIST had some problems. A few source addresses were garbage. +* Replaced Makefile.dj and added -I flags to cord make targets (thanks to +Gary Leavens). +* GC_try_to_collect was broken with the non-incremental collector. +* gc_cleanup destructors could pass the wrong address to +GC_register_finalizer_ignore_self in the presence of multiple +inheritance (thanks to Darrell Schiebel). +* Changed PowerPC Linux stack finding code. + + +== [4.13] 1999-02-19 == + +* Fixed a crucial bug in the Watcom port. There was a redundant declaration +of GC_push_one in gc_priv.h. +* Added FINALIZE_ON_DEMAND. +* Fixed some pre-ANSI cc problems in test.c. +* Removed getpagesize() use for Solaris. It seems to be missing in one +or two versions. +* Fixed bool handling for SPARCCompiler version 4.2. +* Fixed some files in include that had gotten unlinked from the main +copy. +* Some RS/6000 fixes (missing casts). (Thanks to Toralf Foerster.) +* Fixed several problems in GC_debug_realloc, affecting mostly the +FIND_LEAK case. +* GC_exclude_static_roots contained a buggy unsigned comparison to +terminate a loop (thanks to Wilson Ho). +* CORD_str failed if the substring occurred at the last possible position. +(Only affects cord users.) +* Fixed Linux code to deal with RedHat 5.0 and integrated Peter Bigot's +os_dep.c code for dealing with various Linux versions. +* Added workaround for Irix pthreads sigaction bug and possible signal +misdirection problems. + + +== [4.13alpha3] 1998-12-08 == + +* Fixed MSWIN32 recognition test, which interfered with cygwin. +* Removed unnecessary gc_watcom.asm from distribution. Removed +some obsolete README.win32 text. +* Added Alpha Linux incremental GC support (thanks to Philipp Tomsich +for code for retrieving the fault address in a signal handler). +Changed Linux signal handler context argument to be a pointer. +* Took care of some new warnings generated by the 7.3 SGI compiler. +* Integrated Phillip Musumeci's FreeBSD/ELF fixes. +* -DIRIX_THREADS was broken with the -o32 ABI (typo in gc_priv.h). + + +== [4.13alpha2] 1998-08-08 == + +* Fixed more Linux threads problems. +* Changed default GC_free_space_divisor to 3 with new large block allocation +(thanks to Matthew Flatt for some measurements that suggest the old +value sometimes favors space too much over time). +* More CYGWIN32 fixes. +* Integrated Tyson Dowd's Linux-M68K port. +* Minor HP PA and DEC UNIX fixes from Fergus Henderson. +* Integrated Christoffe Raffali's Linux-SPARC changes. +* Allowed for one more GC fixup iteration after a full GC in incremental +mode. Some quick measurements suggested that this significantly +reduces pause times even with smaller GC_RATE values. +* Moved some more GC data structures into GC_arrays. This decreases +pause times and GC overhead, but makes debugging slightly less convenient. +* Fixed namespace pollution problem ("excl_table"). +* Made GC_incremental a constant for -DSMALL_CONFIG, hopefully shrinking +that slightly. +* Added some win32 threads fixes. +* Integrated Ivan Demakov and David Stes' Watcom fixes. +* Various other minor fixes contributed by many people. +* Renamed config.h to gcconfig.h, since config.h tends to be used for +many other things. +* Integrated Matthew Flatt's support for 68K MacOS "far globals". +* Fixed up some of the dynamic library Makefile targets for consistency +across platforms. +* Fixed a USE_MMAP typo that caused out-of-memory handling to fail +on Solaris. +* Added code to test.c to test thread creation a bit more. +* Integrated GC_win32_free_heap (as suggested by Ivan Demakov). +* Fixed Solaris 2.7 stack base finding problem. (This may actually +have been done in an earlier alpha release.) + + +== [4.13alpha1] 1998-02-17 == + +* Changed RS6000 STACKBOTTOM. +* Integrated Patrick Beard's Mac changes. +* Alpha1 didn't compile on Irix m.n, m < 6. +* Replaced Makefile.dj with a new one from Gary Leavens. +* Added Andrew Stitcher's changes to support SCO OpenServer. +* Added PRINT_BLACK_LIST, to allow debugging of high densities of false +pointers. +* Added code to debug allocator to keep track of return address +in GC_malloc caller, thus giving a bit more context. +* Changed default behavior of large block allocator to more +aggressively avoid fragmentation. This is likely to slow down the +collector when it succeeds at reducing space cost. +* Integrated Fergus Henderson's CYGWIN32 changes. They are untested, +but needed for newer versions. +* USE_MMAP had some serious bugs. This caused the collector to fail +consistently on Solaris with -DSMALL_CONFIG. +* Added Linux threads support (thanks to Fergus Henderson). + + +== [4.12] 1997-08-26 == + +* Fixed ElfW definition in dyn_load.c. +This prevented the dynamic library support from compiling on some +older ELF Linux systems. +* Fixed UTS4 port (which I apparently mangled during the integration). +(Thanks to Alistair Crooks.) +* "Make C++" failed on Suns with SC4.0, due to a problem with "bool". +Fixed in gc_priv.h. +* Added more pieces for GNU win32 (thanks to Timothy N. Newsham). +The current state of things should suffice for at least some +applications. +* Changed the out of memory retry count handling. (This matters only +if GC_max_retries > 0, which is no longer the default.) +* If a /proc read failed repeatedly, GC_written_pages was not updated +correctly (thanks to Peter Chubb for diagnosing this). +* Under unlikely circumstances, the allocator could infinite loop in +an out of memory situation (thanks to Kenjiro Taura for +identifying the problem and supplying a fix). +* Fixed a syntactic error in the DJGPP code. Also fixed a test program +problem with DJGPP (thanks to Fergus Henderson and Peter Monks). +* Atomic uncollectible objects were not treated correctly by the +incremental collector. This resulted in weird log statistics and +occasional performance problems (thanks to Peter Chubb for pointing this out). +* Fixed some problems resulting from compilers that don't define +__STDC__. In this case void * and char * were used inconsistently +in some cases. (Void * should not have been used at all. If +you have an ANSI superset compiler that does not define __STDC__, +please compile with -D__STDC__=0. Thanks to Manuel Serrano and others +for pointing out the problem.) +* Fixed a compilation problem on Irix with -n32 and -DIRIX_THREADS. +Also fixed some other IRIX_THREADS problems which may or may not have +had observable symptoms. +* Fixed an HP PA compilation problem in dyn_load.c (thanks to +Philippe Queinnec). +* SEGV fault handlers sometimes did not get reset correctly (thanks +to David Pickens). +* Added a fix for SOLARIS_THREADS on Intel (thanks to David Pickens). +This probably needs more work to become functional. +* Fixed struct sigcontext_struct in os_dep.c for compilation under +Linux 2.1.X (thanks to Fergus Henderson). +* Changed the DJGPP STACKBOTTOM and DATASTART values to those ones suggested +(by Kristian Kristensen). These may still not be right, but it is +it is likely to work more often than what was there before. They may +even be exactly right. +* Added a #include to test_cpp.cc. This appears to help +with HP/UX and gcc (thanks to Assar Westerlund). +* Version 4.11 failed to run in incremental mode on recent 64-bit Irix +kernels. This was a problem related to page unaligned heap segments. +Changed the code to page align heap sections on all platforms. +(I had mistakenly identified this as a kernel problem earlier. +It was not.) +* Version 4.11 did not make allocated storage executable, except on +one or two platforms, due to a bug in a #if test (thanks to David Grove +for pointing this out). +* Added sparc_sunos4_mach_dep.s to support Sun's compilers under SunOS4. +* Added GC_exclude_static_roots. +* Fixed the object size mapping algorithm. This shouldn't matter, +but the old code was ugly. +* Heap checking code could die if one of the allocated objects was +larger than its base address. (Unsigned underflow problem. Thanks +to Clay Spence for isolating the problem.) +* Added RS6000 (AIX) dynamic library support and fixed STACK_BOTTOM (thanks +to Fred Stearns). +* Added Fergus Henderson's patches for improved robustness with large +heaps and lots of blacklisting. +* Added Peter Chubb's changes to support Solaris Pthreads, to support +MMAP allocation in Solaris, to allow Solaris to find dynamic libraries +through /proc, to add malloc_typed_ignore_off_page, and a few other +minor features and bug fixes. +* The Solaris 2 port should not use sbrk. I received confirmation from +Sun that the use of sbrk and malloc in the same program is not +supported. The collector now defines USE_MMAP by default on Solaris. +* Replaced the djgpp makefile with Gary Leavens' version. +* Fixed MSWIN32 detection test. +* Added Fergus Henderson's patches to allow putting the collector into +a DLL under GNU win32. +* Added Ivan V. Demakov's port to Watcom C on x86. +* Added Ian Piumarta's Linux/PowerPC port. +* Added PointerFreeGC to the placement options in gc_cpp.h (suggested by +Brian Burton). This is of course unsafe, and may be controversial. +On the other hand, it seems to be needed often enough that it's worth +adding as a standard facility. +* Add Lars Farm's suggestions on building the collector for MacOS. + + +== [4.12alpha2] == + +(Changes not specified.) + + +== [4.11] 1996-12-03 == + +* Rationalized (hopefully) GC_try_to_collect in an incremental collection +environment. It appeared to not handle a call while a collection was in +progress, and was otherwise too conservative. +* Merged GC_reclaim_or_delete_all into GC_reclaim_all to get rid of some +code. +* Added Patrick Beard's Mac fixes, with substantial completely untested +modifications. +* Fixed the MPROTECT_VDB code to deal with large pages and imprecise +fault addresses (as on an UltraSPARC running Solaris 2.5). Note that this +was not a problem in the default configuration, which uses PROC_VDB. +* The DEC Alpha assembly code needed to restore $gp between calls (thanks to +Fergus Henderson for tracking this down and supplying a patch). +* The write command for "de" was completely broken for large files. +I used the easiest portable fix, which involved changing the semantics +so that f.new is written instead of overwriting f. That's safer anyway. +* Added README.solaris2 with a discussion of the possible problems of +mixing the collector's sbrk allocation with malloc/realloc. +* Changed the data segment starting address for SGI machines. The +old code failed under IRIX6. +* Required double word alignment for MIPS. +* Various minor fixes to remove warnings. +* Attempted to fix some Solaris threads problems (reported by Zhiying Chen). +In particular, the collector could try to fork a thread with the +world stopped as part of GC_thr_init. It also failed to deal with +the case in which the original thread terminated before the whole +process did. +* Added -DNO_EXECUTE_PERMISSION. This has a major performance impact +on the incremental collector under Irix, and perhaps under other +operating systems. +* Added some code to support allocating the heap with mmap. This may +be preferable under some circumstances. +* Integrated dynamic library support for HP (thanks to Knut Tvedten). +* Integrated James Clark's win32 threads support, and made a number +of changes to it (many of which suggested by Pontus Rydin). This is still +not 100% solid. +* Integrated Alistair G. Crooks' support for UTS4 running on an Amdahl +370-class machine. +* Fixed a serious bug in explicitly typed allocation. Objects requiring +large descriptors where handled in a way that usually resulted in +a segmentation fault in the marker (thanks to Jeremy Fitzhardinge +for helping to track this down). +* Added partial support for GNU win32 development (thanks to +Fergus Henderson). +* Added optional support for Java-style finalization semantics (thanks to +Patrick Bridges). This is recommended only for Java implementations. +* GC_malloc_uncollectable faulted instead of returning 0 when out of +memory (thanks to Daniel R. Grayson for noticing). +* Calls to GC_base before the collector was initialized failed on a +DEC Alpha (thanks to Matthew Flatt). +* Added base pointer checking to GC_REGISTER_FINALIZER in debugging mode +(thanks to Jeremy Fitzhardinge). +* GC_debug_realloc failed for uncollectible objects (thanks to +Jeremy Fitzhardinge). +* Explicitly typed allocation could crash if it ran out of memory (thanks to +Jeremy Fitzhardinge). +* Added minimal support for a DEC Alpha running Linux. +* Fixed a problem with allocation of objects whose size overflowed +ptrdiff_t. (This now fails unconditionally, as it should.) +* Added the beginning of Irix pthread support. +* Integrated Xiaokun Zhu's fixes for djgpp 2.01. +* Added SGI-style STL allocator support (gc_alloc.h). +* Fixed a serious bug in README.solaris2. +Multi-threaded programs must include +gc.h with SOLARIS_THREADS defined. +* Changed GC_free so it actually deallocates uncollectible objects (thanks +to Peter Chubb for pointing out the problem). +* Added Linux ELF support for dynamic libraries (thanks to Patrick Bridges). +* Changed the Borland cc configuration so that the assembler is not +required. +* Fixed a bug in the C++ test that caused it to fail in 64-bit +environments. + + +== [4.10t3] 1996-11-18 == + +Some changes related to threads support. + + +== [4.10] 1996-02-19 == + +* Fixed a typo around a call to GC_collect_or_expand in alloc.c. It broke +handling of out of memory. (Thanks to Patrick C. Beard for noticing.) + + +== [4.9] 1996-02-12 == + +* More README.debugging fixes. +* Objects ready for finalization, but not finalized in the same GC +cycle, could be prematurely collected. This occasionally happened +in test_cpp. +* Too little memory was obtained from the system for very large +objects. That could cause a heap explosion if these objects were +not contiguous (e.g. under PCR), and too much of them was blacklisted. +* Due to an improper initialization, the collector was too hesitant to +allocate blacklisted objects immediately after system startup. +* Moved GC_arrays from the data into the bss segment by not explicitly +initializing it to zero. This significantly +reduces the size of executables, and probably avoids some disk accesses +on program startup. It's conceivable that it might break a port that I +didn't test. +* Fixed EMX_MAKEFILE to reflect the gc_c++.h to gc_cpp.h renaming which +occurred a while ago. + + +== [4.8] 1995-11-20 == + +* Changed a "comment" in a MacOS specific part of mach_dep.c that caused +gcc to fail on other platforms. + + +== [4.7] 1995-11-18 == + +* Fixed some compilation problems with -DCHECKSUMS (thanks to Ian Searle). +* Updated some Mac specific files (to synchronize with Patrick C. Beard). +* Fixed a serious bug for machines with non-word-aligned pointers. +(Thanks to Patrick C. Beard for pointing out the problem. The collector +should fail almost any conceivable test immediately on such machines.) + + +== [4.6] 1995-11-09 == + +* Added Linux ELF support (thanks to Arrigo Triulzi). +* GC_base crashed if it was called before any other GC_ routines. +This could happen if a gc_cleanup object was allocated outside the heap +before any heap allocation. +* The heap expansion heuristic was not stable if all objects had finalization +enabled. Fixed finalize.c to count memory in finalization queue and +avoid explicit deallocation. Changed alloc.c to also consider this count. +(This is still not recommended. It's expensive if nothing else. Thanks +to John Ellis for pointing this out.) +* GC_malloc_uncollectable(0) was broken (thanks to Phong Vo for pointing +this out). +* The collector didn't compile under Linux 1.3.X (thanks to Fred Gilham for +pointing this out). The current workaround is ugly, but expected to be +temporary. +* Fixed a formatting problem for SPARC stack traces. +* Fixed some '=='s in os_dep.c that should have been assignments. +Fortunately these were in code that should never be executed anyway (thanks +to Fergus Henderson). +* Fixed the heap block allocator to only drop blacklisted blocks in small +chunks. Made BL_LIMIT self adjusting. (Both of these were in response +to heap growth observed by Paul Graham.) +* Fixed the Metrowerks/68K Mac code to also mark from a6 (thanks to +Patrick C. Beard). +* Significantly updated README.debugging. +* Fixed some problems with longjmps out of signal handlers, especially under +Solaris. Added a workaround for the fact that siglongjmp doesn't appear to +do the right thing with -lthread under Solaris. +* Added MSDOS/djgpp port (thanks to Mitch Harris). +* Added "make reserved_namespace" and "make user_namespace". The +first renames ALL "GC_xxx" identifiers as "_GC_xxx". The second is the +inverse transformation. Note that doing this is guaranteed to break all +clients written for the other names. +* descriptor field for kind NORMAL in GC_obj_kinds with ADD_BYTE_AT_END +defined should be -ALIGNMENT not WORDS_TO_BYTES(-1). This is +a serious bug on machines with pointer alignment of less than a word. +* GC_ignore_self_finalize_mark_proc didn't handle pointers to very near the +end of the object correctly. Caused failures of the C++ test on a DEC Alpha +with g++. +* gc_inl.h still had problems. Partially fixed. Added warnings at the +beginning to hopefully specify the remaining dangers. +* Added DATAEND definition to config.h. +* Fixed some of the .h file organization. Fixed "make floppy". + + +== [4.5] 1995-06-14 == + +* Fixed many minor and one major README bugs (thanks to Franklin Chen +for pointing out many of them). +* Fixed ALPHA/OSF/1 dynamic library support (thanks to Jonathan Bachrach). +* Added incremental GC support (MPROTECT_VDB) for Linux (with some +help from Bruno Haible). +* Altered SPARC recognition tests in gc.h and config.h (mostly as +suggested by Fergus Henderson). +* Added basic incremental GC support for win32, as implemented by +Windows NT and Windows 95. GC_enable_incremental is a no-op +under win32s, which doesn't implement enough of the VM interface. +* Added -DLARGE_CONFIG. +* Fixed GC_..._ignore_off_page to also function without +-DALL_INTERIOR_POINTERS. +* (Hopefully) fixed RS/6000 port. (Only the test was broken.) +* Fixed a performance bug in the non-incremental collector running +on machines supporting incremental collection with MPROTECT_VDB +(e.g. SunOS 4, DEC AXP). This turned into a correctness bug under +win32s with win32 incremental collection. (Not all memory protection +was disabled.) +* Fixed some ppcr related bit rot. +* Caused dynamic libraries to be unregistered before re-registering. +The old way turned out to be a performance bug on some machines. +* GC_root_size was not properly maintained under MSWIN32. +* Added -DNO_DEBUGGING and GC_dump. +* Fixed a couple of bugs arising with SOLARIS_THREADS + +REDIRECT_MALLOC. +* Added NetBSD/M68K port (thanks to Peter Seebach). +* Fixed a serious realloc bug. For certain object sizes, the collector +wouldn't scan the expanded part of the object. (Thanks to Clay Spence +for noticing the problem, and helping me to track it down.) + + +== [4.4] 1995-02-18 == + +* ASM_CLEAR_CODE was erroneously defined for HP +PA machines, resulting in a compile error. +* Fixed OS/2 Makefile to create a library (thanks to Mark Boulter). +* Gc_cleanup objects didn't work if they were created on +the stack. Fixed. +* One copy of Gc_cpp.h in the distribution was out of +synch, and failed to document some known compiler +problems with explicit destructor invocation. Partially +fixed. There are probably other compilers on which +gc_cleanup is miscompiled. +* Fixed Makefile to pass C compiler flags to C++ compiler. +* Added Mac fixes. +* Fixed os_dep.c to work around what appears to be +a new and different VirtualQuery bug under newer +versions of win32s. +* GC_non_gc_bytes was not correctly maintained by +GC_free. Fixed (thanks to James Clark). +* Added GC_set_max_heap_size. +* Changed allocation code to ignore blacklisting if it is preventing +use of a very large block of memory. This has the advantage +that naive code allocating very large objects is much more +likely to work. The downside is you might no +longer find out that such code should really use +GC_malloc_ignore_off_page. +* Changed GC_printf under win32 to close and reopen the file +between calls. FAT file systems otherwise make the log file +useless for debugging. +* Added GC_try_to_collect and GC_get_bytes_since_gc. These +allow starting an abortable collection during idle times. +This facility does not require special OS support. (Thanks to +Michael Spertus of Geodesic Systems for suggesting this. It was +actually an easy addition. Kumar Srikantan previously added a similar +facility to a now ancient version of the collector. At the time +this was much harder, and the result was less convincing.) +* Added some support for the Borland development environment (thanks +to John Ellis and Michael Spertus). +* Removed a misfeature from checksums.c that caused unexpected +heap growth (thanks to Scott Schwartz). +* Changed finalize.c to call WARN if it encounters a finalization cycle. +WARN is defined in gc_priv.h to write a message, usually to stdout. +In many environments, this may be inappropriate. +* Renamed NO_PARAMS in gc.h to GC_NO_PARAMS, thus adhering to my own +naming convention. +* Added GC_set_warn_proc to intercept warnings. +* Fixed Amiga port (thanks to Michel Schinz). +* Fixed a bug in mark.c that could result in an access to unmapped +memory from GC_mark_from_mark_stack on machines with unaligned +pointers. +* Fixed a win32 specific performance bug that could result in scanning of +objects allocated with the system malloc. +* Added REDIRECT_MALLOC. + + +== [4.3] 1994-12-23 == + +* Fixed SPARC alignment problem with GC_DEBUG. +* Fixed Solaris threads /proc workaround. The real +problem was an interaction with mprotect. +* Incorporated fix from Patrick Beard for gc_c++.h (now gc_cpp.h). +* Slightly improved allocator space utilization by +fixing the GC_size_map mechanism. +* Integrated some Sony News and MIPS RISCos 4.51 +patches (thanks to Nobuyuki Hikichi at Software Research Associates, +Inc., Japan). +* Fixed HP_PA alignment problem (thanks to Brian F. Dennis). +* Added GC_same_obj and friends. Changed GC_base +to return 0 for pointers past the end of large objects. +Improved GC_base performance with ALL_INTERIOR_POINTERS +on machines with a slow integer mod operation. +Added GC_PTR_ADD, GC_PTR_STORE, etc. to prepare +for preprocessor. +* changed the default on most UNIX machines to be that +signals are not disabled during critical GC operations. +This is still ANSI-conforming, though somewhat dangerous +in the presence of signal handlers. But the performance +cost of the alternative is sometimes problematic. +Can be changed back with a minor Makefile edit. +* renamed IS_STRING in gc.h, to CORD_IS_STRING, thus +following my own naming convention. Added the function +CORD_to_const_char_star. +* Fixed a gross bug in GC_finalize. Symptom: occasional +address faults in that function (thanks to Anselm Baird-Smith). +* Added port to ICL DRS6000 running DRS/NX. Restructured +things a bit to factor out common code, and remove obsolete +code. Collector should now run under SUNOS5 with either +mprotect or /proc dirty bits. (Thanks to Douglas Steel.) +* More bug fixes and workarounds for Solaris 2.X. (These were +mostly related to putting the collector in a dynamic library, +which didn't really work before. Also SOLARIS_THREADS +didn't interact well with dl_open.) (Thanks to Brian Lewis.) +* Fixed a serious performance bug on the DEC Alpha. The text +segment was getting registered as part of the root set. +(Amazingly, the result was still fast enough that the bug +was not conspicuous.) The fix works on OSF/1, version 1.3. +Hopefully it also works on other versions of OSF/1 ... +* Fixed a bug in GC_clear_roots. +* Fixed a bug in GC_generic_malloc_words_small that broke +gc_inl.h (reported by Antoine de Maricourt). +* Fixed some problems with cord/de under Linux. +* Fixed some cord problems, notably with CORD_riter4. +* Added DG/UX port (thanks to Ben A. Mesander). +* Added finalization registration routines with weaker ordering +constraints. (This is necessary for C++ finalization with +multiple inheritance, since the compiler often adds self-cycles.) +* Filled the holes in the SCO port (thanks to Michael Arnoldus). +* Completely rewritten the documentation in the interface gc_c++.h +(later renamed gc_cpp.h) making it both clearer and more precise (done by +John Ellis). +* The definition of accessibility now ignores pointers from a finalizable +object (an object with a clean-up function) to itself (done by John Ellis). +This allows objects with virtual base classes to be finalizable by the +collector. Compilers typically implement virtual base classes using +pointers from an object to itself, which under the old definition of +accessibility prevented objects with virtual base classes from ever +being collected or finalized. +* gc_cleanup now includes gc as a virtual base. This was enabled by +the change in the definition of accessibility (by John Ellis). +* Added support for operator new[] (by John Ellis). Since most compilers +don't yet support operator new[], it is conditionalized on +-DOPERATOR_NEW_ARRAY. The code is untested, but it's trivial and looks +correct. +* The test program test_gc_c++ (later renamed test_cpp.cc) +tries to test for the C++-specific functionality not tested by the +other programs. +* Added unistd.h include to misc.c. (Needed for ppcr.) +* Added PowerMac port (thanks to Patrick C. Beard). +* Fixed "srcdir"-related Makefile problems. Changed things so +that all externally visible include files always appear in the +include subdirectory of the source. Made gc.h directly +includable from C++ code (thanks to Per Bothner). +* Changed Intel code to also mark from ebp (thanks to Kevin Warne). +* Renamed C++ related files so they could live in a FAT +file system (thanks to Charles Fiterman). +* Changed Windows NT Makefile to include C++ support in +gc.lib. Added C++ test as Makefile target. + + +== [4.2] 1994-08-03 == + +* Multiple bug fixes/workarounds in the Solaris threads version. +(It occasionally failed to locate some register contents for +marking. It also turns out that thr_suspend and friends are +unreliable in Solaris 2.3. Dirty bit reads appear +to be unreliable under some weird +circumstances. My stack marking code +contained a serious performance bug. The new code is +extremely defensive, and has not failed in several CPU +hours of testing. But no guarantees ...) +* Added MacOS support. (Thanks to Patrick C. Beard. +David Chase suggested several improvements.) +* Fixed several syntactic bugs in gc_c++.h and friends. (These +didn't bother g++, but did bother most other compilers.) +Fixed gc_c++.h finalization interface. +* 64 bit alignment for allocated objects was not guaranteed in a +few cases in which it should have been. +* Added GC_malloc_atomic_ignore_off_page. +* Added GC_collect_a_little. +* Added some prototypes to gc.h. +* Some other minor bug fixes (notably in Makefile). +* Fixed OS/2 / EMX port (thanks to Ari Huttunen). +* Fixed AmigaDOS port (thanks to Michel Schinz). +* Fixed the DATASTART definition under Solaris. There +was a 1 in 16K chance of the collector missing the first +64K of static data (and thus crashing). +* Fixed some blatant anachronisms in the README file. +* Fixed PCR-Makefile for upcoming PPCR release. + + +== [4.1] 1994-05-20 == + +* Changed finalization implementation to guarantee that +finalization procedures are called outside of the allocation +lock, making direct use of the interface a little less dangerous. +MAY BREAK EXISTING CLIENTS that assume finalizers +are protected by a lock. Since there seem to be few multi-threaded +clients that use finalization, this is hopefully not much of +a problem. +* Fixed a gross bug in CORD_prev. +* Fixed a bug in blacklst.c that could result in unbounded +heap growth during startup on machines that do not clear +memory obtained from the OS (e.g. win32s). +* Ported de editor to Win32 and win32s. (This is now the only +version with a mouse-sensitive UI. Thanks to Rob Haack for the +implementation based on the generic Windows application template.) +* Added GC_malloc_ignore_off_page to allocate large arrays +in the presence of ALL_INTERIOR_POINTERS. +* Changed GC_call_with_alloc_lock to not disable signals in +the single-threaded case. +* Reduced retry count in GC_collect_or_expand for garbage +collecting when out of memory. +* Made uncollectible allocations bypass black-listing, as they +should. +* Fixed a bug in typed_test in test.c that could cause (legitimate) +GC crashes. +* Fixed some potential synchronization problems in finalize.c +* Fixed a real locking problem in typd_mlc.c. +* Worked around an AIX 3.2 compiler feature that results in +out of bounds memory references. +* Partially worked around an IRIX5.2 beta problem (which may +or may not persist to the final release). +* Fixed a bug in the heap integrity checking code that could +result in explicitly deallocated objects being identified as +smashed. Fixed a bug in the dbg_mlc stack saving code +that caused old argument pointers to be considered live. +* Fixed a bug in CORD_ncmp (and hence CORD_str). +* Repaired the OS2 port, which had suffered from bit rot +in 4.0. Worked around what appears to be CSet/2 V1.0 +optimizer bug. +* Fixed a Makefile bug for target "c++". + + +== [4.0] 1994-04-07 == + +* Added support for Solaris threads (which was possible +only by reimplementing some fraction of Solaris threads, +since Sun doesn't currently make the thread debugging +interface available). +* Added non-threads Win32 and win32s support. +* (Grudgingly, with suitable muttering of obscenities) renamed +files so that the collector distribution could live on a FAT +file system. Files that are guaranteed to be useless on +a PC still have long names. Gc_inline.h and gc_private.h +still exist, but now just include gc_inl.h and gc_priv.h. +* Fixed a really obscure bug in finalization that could cause +undetected mark stack overflows. (I would be surprised if +any real code ever tickled this one.) +* Changed finalization code to dynamically resize the hash +tables it maintains. (This probably does not matter for well- +-written code. It no doubt does for C++ code that overuses +destructors.) +* Added typed allocation primitives. Rewrote the marker to +accommodate them with more reasonable efficiency. This +change should also speed up marking for GC_malloc allocated +objects a little. See gc_typed.h for new primitives. (Thanks to +Zhong Shao performed much of the experimentation that led to the +current typed allocation facility.) +* Improved debugging facilities slightly. Allocation time +stack traces are now kept by default on SPARC/SUNOS4. (Thanks to +Scott Schwartz.) +* Added better support for small heap applications. +* Significantly extended cord package. Fixed a bug in the +implementation of lazily read files. Printf and friends now +have cord variants. Cord traversals are a bit faster. +* Made ALL_INTERIOR_POINTERS recognition the default. +* Fixed de so that it can run in constant space, independent +of file size. Added simple string searching to cords and de. +* Added the Hull-Ellis C++ interface (supplied by Jesse Hull and John Ellis). +* Added dynamic library support for OSF/1 (thanks to Alan Dosser and +Tim Bingham at DEC). +* Changed argument to GC_expand_hp to be expressed +in units of bytes instead of heap blocks. (Necessary +since the heap block size now varies depending on +configuration. The old version was never very clean.) +* Added GC_get_heap_size(). The previous "equivalent" +was broken. +* Restructured the Makefile a bit. +* Added FreeBSD port (provided by Jeffrey Hsu). + + +== [3.7] 1994-03-15 == + +* Added a workaround for an HP/UX compiler bug. +* Fixed another stack clearing performance bug. Reworked +that code once more. + + +== [3.6] 1994-01-14 == + +* fixed a bug in the mark stack growth code that was introduced +in 3.4. +* fixed Makefile to work around DEC AXP compiler tail recursion +bug. + + +== [3.5] == + +* Minor collections now mark from roots only once, if that +doesn't cause an excessive pause. +* The stack clearing heuristic was refined to prevent anomalies +with very heavily recursive programs and sparse stacks. +* Fixed a bug that prevented mark stack growth in some cases. +GC_objects_are_marked should be set to TRUE after a call +to GC_push_roots and as part of GC_push_marked, since +both can now set mark bits. I think this is only a performance +bug, but I wouldn't bet on it. It's certainly very hard to argue +that the old version was correct. +* Fixed an incremental collection bug that prevented it from +working at all when HBLKSIZE != getpagesize() +* Changed dynamic_loading.c to include gc_priv.h before testing +DYNAMIC_LOADING. SunOS dynamic library scanning +must have been broken in 3.4. +* Object size rounding now adapts to program behavior. +* Added a workaround (provided by Manuel Serrano and +colleagues) to a long-standing SunOS 4.X (and 3.X) ld bug +that I had incorrectly assumed to have been squished. +The collector was broken if the text segment size was within +32 bytes of a multiple of 8K bytes, and if the beginning of +the data segment contained interesting roots. The workaround +assumes a demand-loadable executable. The original may have +have "worked" in some other cases. +* Added dynamic library support under IRIX5. +* Added support for EMX under OS/2 (thanks to Ari Huttunen). +* Added support of Motorola 88K processor running CX/UX (by Brent Benson). + + +== [3.4] == + +* Fixed a performance bug in GC_realloc. +* Updated the amiga port. +* Added NetBSD and 386BSD ports (supplied by Alistair G. Crooks). +* Added cord library. +* Added trivial performance enhancement for +ALL_INTERIOR_POINTERS (do not scan last word). + + +== [3.3] 1993-10-02 == + +* PCR-specific bugs (thanks to Neil Sharman). +* Missing locking in GC_free, redundant FASTUNLOCK +in GC_malloc_stubborn, and 2 bugs in +GC_unregister_disappearing_link (pointed out by Neil Sharman). +* Common symbols allocated by the SunOS4.X dynamic loader +were not included in the root set. +* Bug in GC_finalize (reported by Brian Beuning and Alan Dosser). +* Merged Amiga port from Jesper Peterson (untested). +* Merged NeXT port from Thomas Funke (significantly +modified and untested). (Also thanks to Brian D. Carlstrom for +the supplied the NeXT ports.) + + +== [3.2] == + +Fixed a serious and not entirely repeatable bug in +the incremental collector. It appeared only when dirty bit info +on the roots was available, which is normally only under Solaris. +It also added GC_general_register_disappearing_link, and some +testing code. Interface.c disappeared. + + +== [3.1] == + +* A workaround for a SunOS 4.X SPARC C compiler +misfeature that caused problems when the collector was turned into +a dynamic library. +* A fix for a bug in GC_base that could result in a memory fault. +* A fix for a performance bug (and several other misfeatures) pointed +out by Dave Detlefs and Alan Dosser. +* Use of dirty bit information for static data under Solaris 2.X. +* DEC Alpha/OSF1 support (thanks to Alan Dosser). +* Incremental collection on more platforms. +* A more refined heap expansion policy. Less space usage by default. +* Various minor enhancements to reduce space usage, and to reduce +the amount of memory scanned by the collector. +* Uncollectible allocation without per object overhead. +* More conscientious handling of out-of-memory conditions. +* Fixed a bug in debugging stubborn allocation. +* Fixed a bug that resulted in occasional erroneous reporting of smashed +objects with debugging allocation. +* Fixed bogus leak reports of size 4096 blocks with FIND_LEAK. + + +== [3.0] == + +Added generational/incremental collection and stubborn objects. + + +== [2.6] 1993-04-27 == + +(Changes not specified.) + + +== [2.5] == + +* Removed an explicit call to exit(1) +* Fixed calls to GC_printf and GC_err_printf, so the correct number of +arguments are always supplied. The OS/2 C compiler gets confused if +the number of actuals and the number of formals differ. (ANSI C +doesn't require this to work. The ANSI sanctioned way of doing things +causes too many compatibility problems.) + + +== [2.4] 1993-01-26 == + +Added GC_free_space_divisor as a tuning knob, added +support for OS/2 and linux, and fixed the following bugs: +* On machines with unaligned pointers (e.g. Sun 3), every 128th word could +fail to be considered for marking. +* Dynamic_load.c erroneously added 4 bytes to the length of the data and +bss sections of the dynamic library. This could result in a bad memory +reference if the actual length was a multiple of a page. (Observed on +Sun 3. Can probably also happen on a Sun 4.) +(Thanks to Robert Brazile for pointing out that the Sun 3 version +was broken. Dynamic library handling is still broken on Sun 3s +under 4.1.1U1, but apparently not 4.1.1. If you have such a machine, +use -Bstatic.) + + +== [2.3] == + +* Added ALL_INTERIOR_POINTERS. +* Missing declaration of etext in the A/UX version. +* Some PCR root-finding problems. +* Blacklisting was not 100% effective, because the plausible future +heap bounds were being miscalculated. +* GC_realloc didn't handle out-of-memory correctly. +* GC_base could return a nonzero value for addresses inside free blocks. +* test.c wasn't really thread safe, and could erroneously report failure +in a multi-threaded environment. (The locking primitives need to be +replaced for other threads packages.) +* GC_CONS was thoroughly broken. +* On a SPARC with dynamic linking, signals stayed disabled while the +client code was running (thanks to Manuel Serrano). + + +== [2.2] == + +* GC_realloc could fail to extend the size of the object for certain large +object sizes. +* A blatant subscript range error in GC_printf, which unfortunately +wasn't exercised on machines with sufficient stack alignment constraints. +* GC_register_displacement did the wrong thing if it was called after +any allocation had taken place. +* The leak finding code would eventually break after 2048 byte +byte objects leaked. +* interface.c didn't compile. +* The heap size remained much too small for large stacks. +* The stack clearing code behaved badly for large stacks, and perhaps +on HP/PA machines. + + +== [2.1] == + +* The first stable version since 1.9. +* Added support for PPCR. + + +== [2.0] == + +* Introduced a consistent naming convention for collector +routines and added support for registering dynamic library data segments +in the standard mark_roots.c (original code supporting the SunOS dynamic +loader provided by Bill Janssen). Most of the data structures were revamped. +The treatment of interior pointers was completely changed. Finalization +was added. Support for locking was added. Object kinds were added. +We added a black listing facility to avoid allocating at addresses known +to occur as integers somewhere in the address space. Much of this +was accomplished by adapting ideas and code from the PCR collector. +The test program was changed and expanded. + + +== [1.9] 1992-01-29 == + +* fixed a major bug in gc_realloc. + + +== [1.8] == + +* added ULTRIX support in gc_private.h. (Robert Brazile originally supplied +the ULTRIX code. Alan Dosser and Regis Cridlig subsequently provided updates +and information on variation between ULTRIX systems.) + + +== [1.5] == + +* ensure 8 byte alignment for objects allocated on a sparc based machine. + + +== [1.4] == + +* Does not use compile time determined values +for the stack base. This no longer works on Sun 3s, since Sun 3/80s use +a different stack base. We now use a straightforward heuristic on all +machines on which it is known to work (incl. Sun 3s) and compile-time +determined values for the rest. There should really be library calls +to determine such values. + + +== [1.3] == + +* Fixed spurious +assembly language assignments to TMP_SP. Only the assignment in the PC/RT +code is necessary.

(With +-O the compiler recognizes it as dead code.

A few of the files needed +to use the GNU-style build procedure come with a modified GPL license +that appears not to significantly restrict use of the collector, though +use of those files for a purpose other than building the collector may +require the resulting code to be covered by the GPL. + +For more details and the names of other contributors, see the README.md, +doc/README.*, AUTHORS and include/gc.h files. These files describe typical +use of the collector on a machine that is already supported. + +For the version number, see README.md or include/gc_version.h files. + +INSTALLATION: +Under UN*X, Linux: +Alternative 1 (the old way): type "make -f Makefile.direct check". + Link against gc.a. + +Alternative 2 (the new way): type + "./configure --prefix=

; make; make check; make install". + Link against /lib/libgc.a or /lib/libgc.so. + See doc/README.autoconf for details + +Under Windows 95, 98, Me, NT, or 2000: +copy the appropriate makefile to MAKEFILE, read it, and type "nmake check". +(Under Windows, this assumes you have Microsoft command-line tools +installed, and suitably configured.) +Read the machine specific README.XXX in the doc directory if one exists. + +If you need thread support, you should define GC_THREADS as described in +doc/README.macros (configure defines this implicitly unless --disable-threads +option is given). + +If you wish to use the cord (structured string) library with the stand-alone +Makefile.direct, type "make -f Makefile.direct cords". (You may need to +override CC specified in the Makefile. The CORD_printf implementation in +cordprnt.c is known to be less than perfectly portable. The rest of the +package should still work.) See include/cord.h for the API. + +If you wish to use the collector from C++, type "make c++", or use +--enable-cplusplus with the configure script. With Makefile.direct, +"make c++" creates gccpp.a and gctba.a files (you should link with either +gccpp.a or gctba.a). With the alternate (preferred) build process, this +generates libgccpp.a and libgctba.a, and/or libgccpp.so and libgctba.so. +See include/gc_cpp.h and doc/gcinterface.md. + +TYPICAL USE: +Include "gc.h" from the include subdirectory. Link against the +appropriate library ("gc.a" under UN*X).

(The latter is supported +on fewer machines.) On the most common platforms, it can be built +with or without thread support. On a few platforms, it can take advantage +of a multiprocessor to speed up garbage collection. + +Many of the ideas underlying the collector have previously been explored +by others. Notably, some of the run-time systems developed at Xerox PARC +in the early 1980s conservatively scanned thread stacks to locate possible +pointers (cf. Paul Rovner, "On Adding Garbage Collection and Runtime Types +to a Strongly-Typed Statically Checked, Concurrent Language" Xerox PARC +CSL 84-7). Doug McIlroy wrote a simpler fully conservative collector that +was part of version 8 UNIX (tm), but appears to not have received +widespread use. + +Rudimentary tools for use of the collector as a +[leak detector](doc/leak.md) are included, +as is a fairly sophisticated string package "cord" that makes use of the +collector. (See doc/README.cords and H.-J. Boehm, R. Atkinson, and M. Plass, +"Ropes: An Alternative to Strings", Software Practice and Experience 25, 12 +(December 1995), pp. 1315-1330. This is very similar to the "rope" package +in Xerox Cedar, or the "rope" package in the SGI STL or the g++ distribution.) + +Further collector documentation can be found in the +[overview](doc/overview.md). + + +## General Description + +This is a garbage collecting storage allocator that is intended to be +used as a plug-in replacement for C's malloc. + +Since the collector does not require pointers to be tagged, it does not +attempt to ensure that all inaccessible storage is reclaimed. However, +in our experience, it is typically more successful at reclaiming unused +memory than most C programs using explicit deallocation. Unlike manually +introduced leaks, the amount of unreclaimed memory typically stays +bounded. + +In the following, an "object" is defined to be a region of memory allocated +by the routines described below. + +Any objects not intended to be collected must be pointed to either +from other such accessible objects, or from the registers, +stack, data, or statically allocated bss segments. Pointers from +the stack or registers may point to anywhere inside an object. +The same is true for heap pointers if the collector is compiled with +`ALL_INTERIOR_POINTERS` defined, or `GC_all_interior_pointers` is otherwise +set, as is now the default. + +Compiling without `ALL_INTERIOR_POINTERS` may reduce accidental retention +of garbage objects, by requiring pointers from the heap to the beginning +of an object. But this no longer appears to be a significant +issue for most programs occupying a small fraction of the possible +address space. + +There are a number of routines which modify the pointer recognition +algorithm. `GC_register_displacement` allows certain interior pointers +to be recognized even if `ALL_INTERIOR_POINTERS` is not defined. +`GC_malloc_ignore_off_page` allows some pointers into the middle of +large objects to be disregarded, greatly reducing the probability of +accidental retention of large objects. For most purposes it seems +best to compile with `ALL_INTERIOR_POINTERS` and to use +`GC_malloc_ignore_off_page` if you get collector warnings from +allocations of very large objects. See [here](doc/debugging.md) for details. + +_WARNING_: pointers inside memory allocated by the standard `malloc` are not +seen by the garbage collector. Thus objects pointed to only from such a +region may be prematurely deallocated. It is thus suggested that the +standard `malloc` be used only for memory regions, such as I/O buffers, that +are guaranteed not to contain pointers to garbage collectible memory. +Pointers in C language automatic, static, or register variables, +are correctly recognized. (Note that `GC_malloc_uncollectable` has +semantics similar to standard malloc, but allocates objects that are +traced by the collector.) + +_WARNING_: the collector does not always know how to find pointers in data +areas that are associated with dynamic libraries. This is easy to +remedy IF you know how to find those data areas on your operating +system (see `GC_add_roots`). Code for doing this under SunOS, IRIX +5.X and 6.X, HP/UX, Alpha OSF/1, Linux, and win32 is included and used +by default. (See doc/README.win32 for Win32 details.) On other systems +pointers from dynamic library data areas may not be considered by the +collector. If you're writing a program that depends on the collector +scanning dynamic library data areas, it may be a good idea to include +at least one call to `GC_is_visible` to ensure that those areas are +visible to the collector. + +Note that the garbage collector does not need to be informed of shared +read-only data. However, if the shared library mechanism can introduce +discontiguous data areas that may contain pointers then the collector does +need to be informed. + +Signal processing for most signals may be deferred during collection, +and during uninterruptible parts of the allocation process. +Like standard ANSI C mallocs, by default it is unsafe to invoke +malloc (and other GC routines) from a signal handler while another +malloc call may be in progress. + +The allocator/collector can also be configured for thread-safe operation. +(Full signal safety can also be achieved, but only at the cost of two system +calls per malloc, which is usually unacceptable.) + +_WARNING_: the collector does not guarantee to scan thread-local storage +(e.g. of the kind accessed with `pthread_getspecific`). The collector +does scan thread stacks, though, so generally the best solution is to +ensure that any pointers stored in thread-local storage are also +stored on the thread's stack for the duration of their lifetime. +(This is arguably a longstanding bug, but it hasn't been fixed yet.) + + +## Installation and Portability + +The collector operates silently in the default configuration. +In the event of problems, this can usually be changed by defining the +`GC_PRINT_STATS` or `GC_PRINT_VERBOSE_STATS` environment variables. This +will result in a few lines of descriptive output for each collection. +(The given statistics exhibit a few peculiarities. +Things don't appear to add up for a variety of reasons, most notably +fragmentation losses. These are probably much more significant for the +contrived program "test.c" than for your application.) + +On most Unix-like platforms, the collector can be built either using a +GNU autoconf-based build infrastructure (type `./configure; make` in the +simplest case), or with a classic makefile by itself (type +`make -f Makefile.direct`). + +Please note that the collector source repository does not contain configure +and similar auto-generated files, thus the full procedure of autoconf-based +build of `master` branch of the collector could look like: + + git clone https://github.com/ivmai/bdwgc + cd bdwgc + git clone https://github.com/ivmai/libatomic_ops + ./autogen.sh + ./configure + make -j + make check + +Cloning of `libatomic_ops` is now optional provided the compiler supports +atomic intrinsics. + +Below we focus on the collector build using classic makefile. +For the Makefile.direct-based process, typing `make check` instead of `make` +will automatically build the collector and then run `setjmp_test` and `gctest`. +`Setjmp_test` will give you information about configuring the collector, which is +useful primarily if you have a machine that's not already supported. Gctest is +a somewhat superficial test of collector functionality. Failure is indicated +by a core dump or a message to the effect that the collector is broken. Gctest +takes about a second to two to run on reasonable 2007 vintage desktops. It may +use up to about 30 MB of memory. (The multi-threaded version will use more. +64-bit versions may use more.) `make check` will also, as its last step, +attempt to build and test the "cord" string library.) + +Makefile.direct will generate a library gc.a which you should link against. +Typing "make cords" will build the cord library (cord.a). + +The GNU style build process understands the usual targets. `make check` +runs a number of tests. `make install` installs at least libgc, and libcord. +Try `./configure --help` to see the configuration options. It is currently +not possible to exercise all combinations of build options this way. + +All include files that need to be used by clients will be put in the +include subdirectory. (Normally this is just gc.h. `make cords` adds +"cord.h" and "ec.h".) + +The collector currently is designed to run essentially unmodified on +machines that use a flat 32-bit or 64-bit address space. +That includes the vast majority of Workstations and x86 (i386 or later) PCs. + +In a few cases (Amiga, OS/2, Win32, MacOS) a separate makefile +or equivalent is supplied. Many of these have separate README.system +files. + +Dynamic libraries are completely supported only under SunOS/Solaris, +(and even that support is not functional on the last Sun 3 release), +Linux, FreeBSD, NetBSD, IRIX 5&6, HP/UX, Win32 (not win32s) and OSF/1 +on DEC AXP machines plus perhaps a few others listed near the top +of dyn_load.c. On other machines we recommend that you do one of +the following: + + 1. Add dynamic library support (and send us the code). + 2. Use static versions of the libraries. + 3. Arrange for dynamic libraries to use the standard malloc. This is still + dangerous if the library stores a pointer to a garbage collected object. + But nearly all standard interfaces prohibit this, because they deal + correctly with pointers to stack allocated objects. (`strtok` is an + exception. Don't use it.) + +In all cases we assume that pointer alignment is consistent with that +enforced by the standard C compilers. If you use a nonstandard compiler +you may have to adjust the alignment parameters defined in gc_priv.h. +Note that this may also be an issue with packed records/structs, if those +enforce less alignment for pointers. + +A port to a machine that is not byte addressed, or does not use 32 bit +or 64 bit addresses will require a major effort. A port to plain MSDOS +or win16 is hard. + +For machines not already mentioned, or for nonstandard compilers, +some porting suggestions are provided [here](doc/porting.md). + + +## The C Interface to the Allocator + +The following routines are intended to be directly called by the user. +Note that usually only `GC_malloc` is necessary. `GC_clear_roots` and +`GC_add_roots` calls may be required if the collector has to trace +from nonstandard places (e.g. from dynamic library data areas on a +machine on which the collector doesn't already understand them.) On +some machines, it may be desirable to set `GC_stackbottom` to a good +approximation of the stack base (bottom). + +Client code may include "gc.h", which defines all of the following, plus many +others. + + 1. `GC_malloc(bytes)` - Allocate an object of a given size. Unlike malloc, + the object is cleared before being returned to the user. `GC_malloc` will + invoke the garbage collector when it determines this to be appropriate. + GC_malloc may return 0 if it is unable to acquire sufficient space from the + operating system. This is the most probable consequence of running out + of space. Other possible consequences are that a function call will fail + due to lack of stack space, or that the collector will fail in other ways + because it cannot maintain its internal data structures, or that a crucial + system process will fail and take down the machine. Most of these + possibilities are independent of the malloc implementation. + + 2. `GC_malloc_atomic(bytes)` - Allocate an object of a given size that + is guaranteed not to contain any pointers. The returned object is not + guaranteed to be cleared. (Can always be replaced by `GC_malloc`, but + results in faster collection times. The collector will probably run faster + if large character arrays, etc. are allocated with `GC_malloc_atomic` than + if they are statically allocated.) + + 3. `GC_realloc(object, new_bytes)` - Change the size of object to be of + a given size. Returns a pointer to the new object, which may, or may not, + be the same as the pointer to the old object. The new object is taken to + be atomic if and only if the old one was. If the new object is composite + and larger than the original object then the newly added bytes are cleared. + This is very likely to allocate a new object. + + 4. `GC_free(object)` - Explicitly deallocate an object returned by + `GC_malloc` or `GC_malloc_atomic`, or friends. Not necessary, but can be + used to minimize collections if performance is critical. Probably + a performance loss for very small objects (<= 8 bytes). + + 5. `GC_expand_hp(bytes)` - Explicitly increase the heap size. (This is + normally done automatically if a garbage collection failed to reclaim + enough memory. Explicit calls to `GC_expand_hp` may prevent unnecessarily + frequent collections at program startup.) + + 6. `GC_malloc_ignore_off_page(bytes)` - Identical to `GC_malloc`, but the + client promises to keep a pointer to the somewhere within the first GC + heap block (512 .. 4096 bytes or even more, depending on the configuration) + of the object while it is live. (This pointer should normally be + declared volatile to prevent interference from compiler optimizations.) + This is the recommended way to allocate anything that is likely to be + larger than 100 KB or so. (`GC_malloc` may result in a failure to reclaim + such objects.) + + 7. `GC_set_warn_proc(proc)` - Can be used to redirect warnings from the + collector. Such warnings should be rare, and should not be ignored during + code development. + + 8. `GC_enable_incremental()` - Enables generational and incremental + collection. Useful for large heaps on machines that provide access to page + dirty information. Some dirty bit implementations may interfere with + debugging (by catching address faults) and place restrictions on heap + arguments to system calls (since write faults inside a system call may not + be handled well). + + 9. `GC_register_finalizer(object, proc, data, 0, 0)` and friends - Allow for + registration of finalization code. User supplied finalization code + (`(*proc)(object, data)`) is invoked after object becomes unreachable. + For more sophisticated uses, and for finalization ordering issues, see gc.h. + +The global variable `GC_free_space_divisor` may be adjusted up from it +default value of 3 to use less space and more collection time, or down for +the opposite effect. Setting it to 1 will almost disable collections +and cause all allocations to simply grow the heap. + +The variable `GC_non_gc_bytes`, which is normally 0, may be changed to reflect +the amount of memory allocated by the above routines that should not be +considered as a candidate for collection. Careless use may, of course, result +in excessive memory consumption. + +Some additional tuning is possible through the parameters defined +near the top of gc_priv.h. + +If only `GC_malloc` is intended to be used, it might be appropriate to define: + + #define malloc(n) GC_malloc(n) + #define calloc(m,n) GC_malloc((m)*(n)) + +For small pieces of VERY allocation intensive code, gc_inline.h includes +some allocation macros that may be used in place of `GC_malloc` and +friends. + +All externally visible names in the garbage collector start with `GC_`. +To avoid name conflicts, client code should avoid this prefix, except when +accessing garbage collector routines. + +There are provisions for allocation with explicit type information. +This is rarely necessary. Details can be found in gc_typed.h. + + +## The C++ Interface to the Allocator + +The Ellis-Hull C++ interface to the collector is included in the collector +distribution. If you intend to use this, type +`./configure --enable-cplusplus; make` (or `make -f Makefile.direct c++`) +after the initial build of the collector is complete. See gc_cpp.h for the +definition of the interface. This interface tries to approximate the +Ellis-Detlefs C++ garbage collection proposal without compiler changes. + +Very often it will also be necessary to use gc_allocator.h and the +allocator declared there to construct STL data structures. Otherwise +subobjects of STL data structures will be allocated using a system +allocator, and objects they refer to may be prematurely collected. + + +## Use as Leak Detector + +The collector may be used to track down leaks in C programs that are +intended to run with malloc/free (e.g. code with extreme real-time or +portability constraints). To do so define `FIND_LEAK` in Makefile. +This will cause the collector to print a human-readable object description +whenever an inaccessible object is found that has not been explicitly freed. +Such objects will also be automatically reclaimed. + +If all objects are allocated with `GC_DEBUG_MALLOC` (see the next section) +then, by default, the human-readable object description will at least contain +the source file and the line number at which the leaked object was allocated. +This may sometimes be sufficient. (On a few machines, it will also report +a cryptic stack trace. If this is not symbolic, it can sometimes be called +into a symbolic stack trace by invoking program "foo" with +`tools/callprocs.sh foo`. It is a short shell script that invokes adb to +expand program counter values to symbolic addresses. It was largely supplied +by Scott Schwartz.) + +Note that the debugging facilities described in the next section can +sometimes be slightly LESS effective in leak finding mode, since in the latter +`GC_debug_free` actually results in reuse of the object. (Otherwise the +object is simply marked invalid.) Also, note that most GC tests are not +designed to run meaningfully in `FIND_LEAK` mode. + + +## Debugging Facilities + +The routines `GC_debug_malloc`, `GC_debug_malloc_atomic`, `GC_debug_realloc`, +and `GC_debug_free` provide an alternate interface to the collector, which +provides some help with memory overwrite errors, and the like. +Objects allocated in this way are annotated with additional +information. Some of this information is checked during garbage +collections, and detected inconsistencies are reported to stderr. + +Simple cases of writing past the end of an allocated object should +be caught if the object is explicitly deallocated, or if the +collector is invoked while the object is live. The first deallocation +of an object will clear the debugging info associated with an +object, so accidentally repeated calls to `GC_debug_free` will report the +deallocation of an object without debugging information. Out of +memory errors will be reported to stderr, in addition to returning `NULL`. + +`GC_debug_malloc` checking during garbage collection is enabled +with the first call to this function. This will result in some +slowdown during collections. If frequent heap checks are desired, +this can be achieved by explicitly invoking `GC_gcollect`, e.g. from +the debugger. + +`GC_debug_malloc` allocated objects should not be passed to `GC_realloc` +or `GC_free`, and conversely. It is however acceptable to allocate only +some objects with `GC_debug_malloc`, and to use `GC_malloc` for other objects, +provided the two pools are kept distinct. In this case, there is a very +low probability that `GC_malloc` allocated objects may be misidentified as +having been overwritten. This should happen with probability at most +one in 2**32. This probability is zero if `GC_debug_malloc` is never called. + +`GC_debug_malloc`, `GC_debug_malloc_atomic`, and `GC_debug_realloc` take two +additional trailing arguments, a string and an integer. These are not +interpreted by the allocator. They are stored in the object (the string is +not copied). If an error involving the object is detected, they are printed. + +The macros `GC_MALLOC`, `GC_MALLOC_ATOMIC`, `GC_REALLOC`, `GC_FREE`, +`GC_REGISTER_FINALIZER` and friends are also provided. These require the same +arguments as the corresponding (nondebugging) routines. If gc.h is included +with `GC_DEBUG` defined, they call the debugging versions of these +functions, passing the current file name and line number as the two +extra arguments, where appropriate. If gc.h is included without `GC_DEBUG` +defined then all these macros will instead be defined to their nondebugging +equivalents. (`GC_REGISTER_FINALIZER` is necessary, since pointers to +objects with debugging information are really pointers to a displacement +of 16 bytes from the object beginning, and some translation is necessary +when finalization routines are invoked. For details, about what's stored +in the header, see the definition of the type oh in dbg_mlc.c file.) + + +## Incremental/Generational Collection + +The collector normally interrupts client code for the duration of +a garbage collection mark phase. This may be unacceptable if interactive +response is needed for programs with large heaps. The collector +can also run in a "generational" mode, in which it usually attempts to +collect only objects allocated since the last garbage collection. +Furthermore, in this mode, garbage collections run mostly incrementally, +with a small amount of work performed in response to each of a large number of +`GC_malloc` requests. + +This mode is enabled by a call to `GC_enable_incremental`. + +Incremental and generational collection is effective in reducing +pause times only if the collector has some way to tell which objects +or pages have been recently modified. The collector uses two sources +of information: + + 1. Information provided by the VM system. This may be provided in one of + several forms. Under Solaris 2.X (and potentially under other similar + systems) information on dirty pages can be read from the /proc file system. + Under other systems (e.g. SunOS4.X) it is possible to write-protect + the heap, and catch the resulting faults. On these systems we require that + system calls writing to the heap (other than read) be handled specially by + client code. See `os_dep.c` for details. + + 2. Information supplied by the programmer. The object is considered dirty + after a call to `GC_end_stubborn_change` provided the library has been + compiled suitably. It is typically not worth using for short-lived objects. + Note that bugs caused by a missing `GC_end_stubborn_change` or + `GC_reachable_here` call are likely to be observed very infrequently and + hard to trace. + + +## Bugs + +Any memory that does not have a recognizable pointer to it will be +reclaimed. Exclusive-or'ing forward and backward links in a list +doesn't cut it. + +Some C optimizers may lose the last undisguised pointer to a memory +object as a consequence of clever optimizations. This has almost +never been observed in practice. + +This is not a real-time collector. In the standard configuration, +percentage of time required for collection should be constant across +heap sizes. But collection pauses will increase for larger heaps. +They will decrease with the number of processors if parallel marking +is enabled. + +(On 2007 vintage machines, GC times may be on the order of 5 ms +per MB of accessible memory that needs to be scanned and processed. +Your mileage may vary.) The incremental/generational collection facility +may help in some cases. + + +## Feedback, Contribution, Questions and Notifications + +Please address bug reports and new feature ideas to +[GitHub issues](https://github.com/ivmai/bdwgc/issues).

I haven't checked if it still +works under gcc, because I don't have gcc for Amiga. But I have +updated 'Makefile', and hope it compiles fine. + + +WHATS NEW: + +1. + Made a pretty big effort in preventing GC allocating-functions from + returning chip-mem. + + The lower part of the new file AmigaOS.c does this in various ways, mainly by + wrapping GC_malloc, GC_malloc_atomic, GC_malloc_uncollectable, + GC_malloc_atomic_uncollectable, GC_malloc_ignore_off_page + and GC_malloc_atomic_ignore_off_page. GC_realloc is also wrapped, but + doesn't do the same effort in preventing to return chip-mem. + Other allocating-functions (e.g., GC_*_typed) can probably be + used without any problems, but beware that the warn hook will not be called. + In case of problems, don't define GC_AMIGA_FASTALLOC. + + Programs using more time actually using the memory allocated + (instead of just allocate and free rapidly) have + the most to earn on this, but even gctest now normally runs twice + as fast and uses less memory, on my poor 8 MB machine. + + The changes have only effect when there is no more + fast-mem left. But with the way GC works, it + could happen quite often. Beware that an atexit handler had to be added, + so using the abort() function will make a big memory-loss. + If you absolutely must call abort() instead of exit(), try calling + the GC_amiga_free_all_mem function before abort(). + + New Amiga-specific compilation flags: + + GC_AMIGA_FASTALLOC - By NOT defining this option, GC will work like before, + it will not try to force fast-mem out of the OS, and + it will use normal calloc for allocation, and the rest + of the following flags will have no effect. + + GC_AMIGA_ONLYFAST - Makes GC never to return chip-mem. GC_AMIGA_RETRY have + no effect if this flag is set. + + GC_AMIGA_GC - If gc returns NULL, do a GC_gcollect, and try again. This + usually is a success with the standard GC configuration. + It is also the most important flag to set to prevent + GC from returning chip-mem. Beware that it slows down a lot + when a program is rapidly allocating/deallocating when + there's either very little fast-memory left or very little + chip-memory left. It's not a very common situation, but gctest + sometimes (very rare) use many minutes because of this. + + GC_AMIGA_RETRY - If gc succeed allocating memory, but it is chip-mem, + try again and see if it is fast-mem. Most of the time, + it will actually return fast-mem for the second try. + I have set max number of retries to 9 or size/5000. You + can change this if you like. (see GC_amiga_rec_alloc()) + + GC_AMIGA_PRINTSTATS - Gather some statistics during the execution of a + program, and prints out the info when the atexit-handler + is called. + + My recommendation is to set all this flags, except GC_AMIGA_PRINTSTATS and + GC_AMIGA_ONLYFAST. + + If your program demands high response-time, you should + not define GC_AMIGA_GC, and possible also define GC_AMIGA_ONLYFAST. + GC_AMIGA_RETRY does not seem to slow down much. + + Also, when compiling up programs, and GC_AMIGA_FASTALLOC was not defined when + compiling gc, you can define GC_AMIGA_MAKINGLIB to avoid having these allocation- + functions wrapped. (see gc.h) + + Note that GC_realloc must not be called before any of + the other above mentioned allocating-functions have been called. (shouldn't be + any programs doing so either, I hope). + + Another note. The allocation-function is wrapped when defining + GC_AMIGA_FASTALLOC by letting the function go thru the new + GC_amiga_allocwrapper_do function-pointer (see gc.h). Means that + sending function-pointers, such as GC_malloc, GC_malloc_atomic, etc., + for later to be called, e.g., like this, (*GC_malloc_function_pointer)(size), + will not wrap the function. This is normally not a big problem, unless + all allocation function is called like this, which will cause the + atexit un-allocating function never to be called. Then you either + have to manually add the atexit handler, or call the allocation- + functions function-pointer functions like this; + (*GC_amiga_allocwrapper_do)(size,GC_malloc_function_pointer). + There are probably better ways this problem could be handled, unfortunately, + I didn't find any without rewriting or replacing a lot of the GC-code, which + I really didn't want to. (Making new GC_malloc_* functions, and just + defining, e.g., GC_malloc as GC_amiga_malloc should work too). + + + New Amiga-specific function: + + void GC_amiga_set_toany(void (*func)(void)); + + 'func' is a function that will be called right before gc has to change + allocation-method from MEMF_FAST to MEMF_ANY. I.e., when it is likely + it will return chip-mem. + + +2. A few small compiler-specific additions to make it compile with SAS/C again. + +3. Updated and rewritten the SMakefile.amiga, so that it works again and that + the "unnecessary" 'SCOPTIONS' files could be removed. Also included + the cord-smakefile stuff in the main smakefile, so that the cord smakefile + could be removed too. By typing "smake -f SMakefile.amiga", both gc.lib and + cord.lib will be made. + + + +STILL MISSING: + +Programs can not be started from workbench, at least not for SAS/C.

I (Michel Schinz) +modified it slightly to reflect the changes made in the new official +distributions, and to take advantage of the new SAS/C 6.x features. I also +created a makefile to compile the "cord" package (see the cord +subdirectory). + +TECHNICAL NOTES + +In addition to Jesper's notes, I have the following to say: + +- gctest checks to see if the code segment is added to the root set or not, + and complains if it is. The only problem is that, as far as I know, it is + impossible to know which segments are code segments and which are data + segments (there are indeed solutions to this problem, like scanning the + program on disk or patch the LoadSeg functions, but they are rather + complicated). The solution I have chosen (see os_dep.c) is to test whether + the program counter is in the segment we are about to add to the root set, + and if it is, to skip the segment. The problems are that this solution is + rather awkward and that it works only for one code segment. This means that + if your program has more than one code segment, all of them but one will be + added to the root set. This isn't a big problem in fact, since the + collector will continue to work correctly, but it may be slower. + + Anyway, the code which decides whether to skip a segment or not can be + removed simply by not defining AMIGA_SKIP_SEG. But notice that if you do + so, gctest will complain (it will say that "GC_is_visible produced wrong + failure indication"). However, it may be useful if you happen to have + pointers stored in a code segment (you really shouldn't). + + If anyone has a good solution to the problem of finding, when a program + is loaded in memory, whether a segment is a code or a data segment, + please let me know. + + + Jesper Peterson's notes + +ADDITIONAL NOTES FOR AMIGA PORT + +These notes assume some familiarity with Amiga internals. + +WHY I PORTED TO THE AMIGA + +The sole reason why I made this port was as a first step in getting +the Sather(*) language on the Amiga. A port of this language will +be done as soon as the Sather 1.0 sources are made available to me. +Given this motivation, the garbage collection (GC) port is rather +minimal. + +(*) For information on Sather read the comp.lang.sather newsgroup. + +LIMITATIONS + +This port assumes that the startup code linked with target programs +is that supplied with SAS/C versions 6.0 or later. This allows +assumptions to be made about where to find the stack base pointer +and data segments when programs are run from WorkBench, as opposed +to running from the CLI. The compiler dependent code is all in the +GC_get_stack_base() and GC_register_data_segments() functions, but +may spread as I add Amiga specific features. + +Given that SAS/C was assumed, the port is set up to be built with +"smake" using the "SMakefile". Compiler options in "SCoptions" can +be set with "scopts" program. Both "smake" and "scopts" are part of +the SAS/C commercial development system. + +In keeping with the porting philosophy outlined above, this port +will not behave well with Amiga specific code. Especially not inter- +process communications via messages, and setting up public structures like +Intuition objects or anything else in the system lists. For the +time being the use of this library is limited to single threaded +ANSI/POSIX compliant or near-compliant code. (i.e., stick to stdio +for now).

All the code to stop and +start the world is located in darwin_stop_world.c. + +Since not all uses of the GC enable clients to override pthread_create() +before threads have been created, the code for stopping the world has +been rewritten to look for threads using Mach kernel calls. Each +thread identified in this way is suspended and resumed as above. In +addition, since Mach kernel threads do not contain pointers to their +stacks, a stack-walking function has been written to find the stack +limits. Given an initial stack pointer (for the current thread, a +pointer to a stack-allocated local variable will do; for a non-active +thread, we grab the value of register 1 (on PowerPC)), it +will walk the PPC Mach-O-ABI compliant stack chain until it reaches the +top of the stack.

Under unusual + conditions, this may cause unexpected heap growth. + +5) The combination of GC_THREADS, REDIRECT_MALLOC, and incremental + collection is probably not fully reliable, though it now seems to work + in simple cases. + +6) Thread local storage may not be viewed as part of the root set by the + collector. This probably depends on the linuxthreads version. For the + time being, any collectible memory referenced by thread local storage + should also be referenced from elsewhere, or be allocated as uncollectible. + (This is really a bug that should be fixed somehow. Actually, the + collector probably gets things right, on Linux at least, if there are not + too many tls locations and if dlopen is not used.) + + +M68K LINUX: +(From Richard Zidlicky) +The bad news is that it can crash every linux-m68k kernel on a 68040, +so an additional test is needed somewhere on startup.

This violates a number of known coding +standards. On the other hand, it seems to be the only practical way to +support this many platforms without excessive code duplication. + +A few guidelines have mostly been followed in order to keep this manageable: + +1) #if and #ifdef directives are properly indented whenever easily possible. +All known C compilers allow whitespace between the "#" and the "if" to make +this possible. ANSI C also allows white space before the "#", though we +avoid that. It has the known disadvantages that it differs from the normal +GNU conventions, and that it makes patches larger than otherwise necessary. +In my opinion, it's still well worth it, for the same reason that we indent +ordinary "if" statements. + +2) Whenever possible, tests are performed on the macros defined in gcconfig.h +instead of directly testing platform-specific predefined macros. This makes +it relatively easy to adapt to new compilers with a different set of +predefined macros. Currently these macros generally identify platforms +instead of features. In many cases, this is a mistake. + +Many of the tested configuration macros are at least somewhat defined in +either include/private/gcconfig.h or in Makefile.direct. Here is an attempt +at documenting these macros: (Thanks to Walter Bright for suggesting +this.) + +MACRO EXPLANATION +----- ----------- + +GC_DEBUG Tested by gc.h. Causes all-upper-case macros to + expand to calls to debug versions of collector routines. + +GC_NAMESPACE Tested by gc_cpp.h. Causes gc_cpp symbols to be defined + in "boehmgc" namespace. + +GC_DEBUG_REPLACEMENT Tested by gc.h. Causes GC_MALLOC/REALLOC() to be + defined as GC_debug_malloc/realloc_replacement(). + +GC_NO_THREAD_REDIRECTS Tested by gc.h. Prevents redirection of thread + creation routines etc. to GC_ versions. Requires the + programmer to explicitly handle thread registration. + +GC_NO_THREAD_DECLS Tested by gc.h. Windows only. Do not declare + Windows thread creation routines and do not include windows.h. + +GC_DONT_INCLUDE_WINDOWS_H Tested by gc.h. Windows only. Do not include + windows.h from gc.h (but Windows-specific thread creation + routines are declared). + +GC_UNDERSCORE_STDCALL Tested by gc.h. Explicitly prefix exported/imported + WINAPI (__stdcall) symbols with '_' (underscore). Could be + used with MinGW (for x86) compiler (in conjunction with + GC_DLL) to follow MS conventions for __stdcall symbols naming. + +_ENABLE_ARRAYNEW + #define'd by the Digital Mars C++ compiler when + operator new[] and delete[] are separately + overloadable. Used in gc_cpp.h. + +GC_NO_INLINE_STD_NEW Tested by gc_cpp.cc and gc_cpp.h. Windows only. + Define the system-wide new and delete operators in gccpp.dll + instead of providing an inline version of the operators. + +_DLL Tested by gc_config_macros.h. Defined by Visual C++ if runtime + dynamic libraries are in use. Used (only if none of GC_DLL, + GC_NOT_DLL, __GNUC__ are defined) to test whether + __declspec(dllimport) needs to be added to declarations + to support the case in which the collector is in a DLL. + +GC_DLL Defined by user if dynamic libraries are being built + or used. Also set by gc.h if _DLL is defined (except for + mingw) while GC_NOT_DLL and __GNUC__ are both undefined. + This is the macro that is tested internally to determine + whether the GC is in its own dynamic library. May need + to be set by clients before including gc.h. Note that + inside the GC implementation it indicates that the + collector is in its own dynamic library, should export + its symbols, etc. But in clients it indicates that the + GC resides in a different DLL, its entry points should + be referenced accordingly, and precautions may need to + be taken to properly deal with statically allocated + variables in the main program. Used for Windows. + Also used by GCC v4+ (only when the dynamic shared library + is being built) to hide internally used symbols. + +GC_NOT_DLL User-settable macro that overrides _DLL, e.g. if runtime + dynamic libraries are used, but the collector is in a static + library. Tested by gc_config_macros.h. + +GC_MARKERS= Set the desired number of marker threads. If not defined or + defined to zero, then the collector decides based on the + number of CPU cores. Only if compiled with PARALLEL_MARK. + + +These define arguments influence the collector configuration: + +GC_REQUIRE_WCSDUP Force GC to export GC_wcsdup() (the Unicode version + of GC_strdup); could be useful in the leak-finding mode. Clients should + define it before including gc.h if the function is needed. + +FIND_LEAK Causes GC_find_leak to be initially set. This causes the + collector to assume that all inaccessible objects should have been + explicitly deallocated, and reports exceptions. Finalization and the test + program are not usable in this mode. + +GC_FINDLEAK_DELAY_FREE Turns on deferred freeing of objects in the + leak-finding mode letting the collector to detect alter-object-after-free + errors as well as detect leaked objects sooner (instead of only when program + terminates). Has no effect if SHORT_DBG_HDRS. + +GC_ABORT_ON_LEAK Causes the application to be terminated once leaked or + smashed (corrupted on use-after-free) objects are found (after printing the + information about that objects). + +SUNOS5SIGS Solaris-like signal handling. This is probably misnamed, + since it really doesn't guarantee much more than POSIX. Currently set only + for DRSNX, FreeBSD, HP/UX and Solaris. + +PCR Set if the collector is being built as part of the Xerox Portable + Common Runtime. + +GC_THREADS Should set the appropriate one of the below macros, + except GC_WIN32_PTHREADS, which must be set explicitly. Tested by gc.h. + IMPORTANT: GC_THREADS macro (or the relevant platform-specific deprecated + one) must normally also be defined by the client before including gc.h. + This redefines thread primitives to invoke the GC_ wrappers instead. + Alternatively, linker-based symbol interception can be used on a few + platforms. + +GC_SOLARIS_THREADS Enables support for Solaris pthreads. + Must also define _REENTRANT. Deprecated, use GC_THREADS instead. + +GC_IRIX_THREADS Enables support for Irix pthreads. See README.sgi. + Deprecated, use GC_THREADS instead. + +GC_HPUX_THREADS Enables support for HP/UX 11 pthreads. + Also requires _REENTRANT or _POSIX_C_SOURCE=199506L. See README.hp. + Deprecated, use GC_THREADS instead. + +GC_LINUX_THREADS Enables support for Xavier Leroy's Linux threads + or NPTL threads. See README.linux. _REENTRANT may also be required. + Deprecated, use GC_THREADS instead. + +GC_OSF1_THREADS Enables support for Tru64 pthreads. Deprecated, use + GC_THREADS instead. + +GC_FREEBSD_THREADS Enables support for FreeBSD pthreads. Appeared to run + into some underlying thread problems. Deprecated, use GC_THREADS instead. + +GC_NETBSD_THREADS Enables support for NetBSD pthreads. Deprecated, use + GC_THREADS instead. + +GC_OPENBSD_THREADS Enables support for OpenBSD pthreads. Deprecated, + use GC_THREADS instead. + +GC_DARWIN_THREADS Enables support for Mac OS X pthreads. Deprecated, + use GC_THREADS instead. + +GC_AIX_THREADS Enables support for IBM AIX threads. Deprecated, use + GC_THREADS instead. + +GC_DGUX386_THREADS Enables support for DB/UX x86 threads. + See README.DGUX386. (Probably has not been tested recently.) Deprecated, + use GC_THREADS instead. + +GC_WIN32_THREADS Enables support for Win32 threads. Deprecated, + use GC_THREADS instead. + +GC_WIN32_PTHREADS Enables support for pthreads-win32 (or other + non-Cygwin pthreads library for Windows). This cannot be enabled + automatically by GC_THREADS, which would assume Win32 native threads. + +PTW32_STATIC_LIB Causes the static version of the Mingw pthreads + library to be used. Requires GC_WIN32_PTHREADS. + +GC_PTHREADS_PARAMARK Causes pthread-based parallel mark implementation + to be used even if GC_WIN32_PTHREADS is undefined. (Useful for WinCE.) + +ALL_INTERIOR_POINTERS Allows all pointers to the interior of objects to be + recognized. (See gc_priv.h for consequences.) Alternatively, + GC_all_interior_pointers can be set at process initialization time. + +SMALL_CONFIG Tries to tune the collector for small heap sizes, + usually causing it to use less space in such situations. Incremental + collection no longer works in this case. Also, removes some + statistic-printing code. Turns off some optimization algorithms (like data + prefetching in the mark routine). + +NO_CLOCK Do not use system clock. Disables some statistic printing. + +GC_DISABLE_INCREMENTAL Turn off the incremental collection support. + +NO_INCREMENTAL Causes the GC test programs to not invoke the incremental mode + of the collector. This has no impact on the generated library, only on the + test programs. (This is often useful for debugging failures unrelated to + incremental GC.) + +LARGE_CONFIG Tunes the collector for unusually large heaps. + Necessary for heaps larger than about 4 GiB on most (64-bit) machines. + Recommended for heaps larger than about 500 MiB. Not recommended for + embedded systems. Could be used in conjunction with SMALL_CONFIG to + generate smaller code (by disabling incremental collection support, + statistic printing and some optimization algorithms). + +DONT_ADD_BYTE_AT_END Meaningful only with ALL_INTERIOR_POINTERS or + GC_all_interior_pointers = 1. Normally ALL_INTERIOR_POINTERS + causes all objects to be padded so that pointers just past the end of + an object can be recognized. This can be expensive. (The padding + is normally more than one byte due to alignment constraints.) + DONT_ADD_BYTE_AT_END disables the padding. + +NO_EXECUTE_PERMISSION May cause some or all of the heap to not + have execute permission, i.e. it may be impossible to execute + code from the heap. Affects the incremental collector and memory unmapping. + It may greatly improve the performance, since this may avoid some expensive + cache synchronization. Portable clients should call + GC_set_pages_executable(1) at the process initialization time if the + execute permission is required. + +GC_NO_OPERATOR_NEW_ARRAY Declares that the C++ compiler does not + support the new syntax "operator new[]" for allocating and deleting arrays. + See gc_cpp.h for details. No effect on the C part of the collector. + This is defined implicitly in a few environments. Must also be defined + by clients that use gc_cpp.h. + +REDIRECT_MALLOC= Causes malloc to be defined as alias for X. + Unless the following macros are defined, realloc is also redirected + to GC_realloc, and free is redirected to GC_free. + Calloc and str[n]dup are redefined in terms of the new malloc. X should + be either GC_malloc or GC_malloc_uncollectable, or + GC_debug_malloc_replacement. (The latter invokes GC_debug_malloc + with dummy source location information, but still results in + properly remembered call stacks on Linux/x86 and Solaris/SPARC. + It requires that the following two macros also be used.) + The former is occasionally useful for working around leaks in code + you don't want to (or can't) look at. It may not work for + existing code, but it often does. Neither works on all platforms, + since some ports use malloc or calloc to obtain system memory. + (Probably works for UNIX, and Win32.) If you build with DBG_HDRS_ALL, + you should only use GC_debug_malloc_replacement as a malloc + replacement. + +REDIRECT_REALLOC= Causes realloc to be redirected to X. + The canonical use is REDIRECT_REALLOC=GC_debug_realloc_replacement, + together with REDIRECT_MALLOC=GC_debug_malloc_replacement to + generate leak reports with call stacks for both malloc and realloc. + This also requires REDIRECT_FREE. + +REDIRECT_FREE= Causes free to be redirected to X. The canonical use + is REDIRECT_FREE=GC_debug_free. + +IGNORE_FREE Turns calls to free into a no-op. Only useful with + REDIRECT_MALLOC. + +NO_DEBUGGING Removes GC_dump and the debugging routines it calls. + Reduces code size slightly at the expense of debuggability. + +GC_DUMP_REGULARLY Generate regular debugging dumps. + +DEBUG_THREADS Turn on printing additional thread-support debugging + information. + +GC_COLLECT_AT_MALLOC= Force garbage collection at every + GC_malloc_* call with the size greater than the specified value. + (Might be useful for application debugging or in find-leak mode.) + +JAVA_FINALIZATION Makes it somewhat safer to finalize objects out of + order by specifying a nonstandard finalization mark procedure (see + finalize.c). Objects reachable from finalizable objects will be marked + in a separate post-pass, and hence their memory won't be reclaimed. + Not recommended unless you are implementing a language that specifies + these semantics. Actually, the macro determines only the initial value + of GC_java_finalization variable. + +FINALIZE_ON_DEMAND Causes finalizers to be run only in response + to explicit GC_invoke_finalizers() calls. Actually, the macro only + determines the initial value of GC_finalize_on_demand. + +GC_NO_FINALIZATION Exclude finalization support (for smaller code size). + +GC_TOGGLE_REFS_NOT_NEEDED Exclude toggle-refs support. + +GC_ATOMIC_UNCOLLECTABLE Includes code for GC_malloc_atomic_uncollectable. + This is useful if either the vendor malloc implementation is poor, + or if REDIRECT_MALLOC is used. + +MARK_BIT_PER_GRANULE Requests that a mark bit (or often byte) + be allocated for each allocation granule, as opposed to each object. + This often improves speed, possibly at some cost in space and/or + cache footprint. Normally it is best to let this decision be + made automatically depending on platform. + +MARK_BIT_PER_OBJ Requests that a mark bit be allocated for each + object instead of allocation granule. The opposite of + MARK_BIT_PER_GRANULE. + +HBLKSIZE= Explicitly sets the heap block size (where ddd is a power of + 2 between 512 and 16384). Each heap block is devoted to a single size and + kind of object. For the incremental collector it makes sense to match + the most likely page size. Otherwise large values result in more + fragmentation, but generally better performance for large heaps. + +USE_MMAP Use MMAP instead of sbrk to get new memory. + Works for Linux, FreeBSD, Cygwin, Solaris and Irix. + +USE_MUNMAP Causes memory to be returned to the OS under the right + circumstances. Works under some Unix, Linux and Windows versions. + Requires USE_MMAP except for Windows. + +USE_WINALLOC (Cygwin only) Use Win32 VirtualAlloc (instead of sbrk or mmap) + to get new memory. Useful if memory unmapping (USE_MUNMAP) is enabled. + +MUNMAP_THRESHOLD= Set the desired memory blocks unmapping + threshold (the number of sequential garbage collections for which + a candidate block for unmapping should remain free). + +GC_FORCE_UNMAP_ON_GCOLLECT Set "unmap as much as possible on explicit GC" + mode on by default. The mode could be changed at run-time. Has no effect + unless unmapping is turned on. Has no effect on implicitly-initiated + garbage collections. + +PRINT_BLACK_LIST Whenever a black list entry is added, i.e. whenever + the garbage collector detects a value that looks almost, but not quite, + like a pointer, print both the address containing the value, and the + value of the near-bogus-pointer. Can be used to identify regions of + memory that are likely to contribute misidentified pointers. + +KEEP_BACK_PTRS Add code to save back pointers in debugging headers + for objects allocated with the debugging allocator. If all objects + through GC_MALLOC with GC_DEBUG defined, this allows the client + to determine how particular or randomly chosen objects are reachable + for debugging/profiling purposes. The gc_backptr.h interface is + implemented only if this is defined. + +GC_ASSERTIONS Enable some internal GC assertion checking. It is intended + primarily for debugging of the garbage collector itself, but could also + help to identify cases of incorrect GC usage by a client. + +DBG_HDRS_ALL Make sure that all objects have debug headers. Increases + the reliability (from 99.9999% to 100% mod. bugs) of some of the debugging + code (especially KEEP_BACK_PTRS). Makes SHORT_DBG_HDRS possible. + Assumes that all client allocation is done through debugging allocators. + +SHORT_DBG_HDRS Assume that all objects have debug headers. Shorten + the headers to minimize object size, at the expense of checking for + writes past the end of an object. This is intended for environments + in which most client code is written in a "safe" language, such as + Scheme or Java. Assumes that all client allocation is done using + the GC_debug_ functions, or through the macros that expand to these, + or by redirecting malloc to GC_debug_malloc_replacement. + (Also eliminates the field for the requested object size.) + Occasionally could be useful for debugging of client code. Slows down the + collector somewhat, but not drastically. + +SAVE_CALL_COUNT= Set the number of call frames saved with objects + allocated through the debugging interface. Affects the amount of + information generated in leak reports. Only matters on platforms + on which we can quickly generate call stacks, currently Linux/x86, + Linux/SPARC, Solaris/SPARC, and platforms that provide execinfo.h. + Default is zero. On x86, client code should NOT be compiled with + -fomit-frame-pointer. + +SAVE_CALL_NARGS= Set the number of functions arguments to be saved + with each call frame. Default is zero. Ignored if we don't know how to + retrieve arguments on the platform. + +CHECKSUMS Reports on erroneously clear dirty bits (at a substantial + performance cost). Use only for debugging of the incremental collector. + Not compatible with USE_MUNMAP or threads. + +GC_GCJ_SUPPORT Includes support for gcj (and possibly other systems + that include a pointer to a type descriptor in each allocated object). + +USE_I686_PREFETCH Causes the collector to issue Pentium III style + prefetch instructions. No effect except on Linux/x86 platforms. + Empirically the code appears to still run correctly on Pentium II + processors, though with no performance benefit. May not run on other + x86 processors probably. In some cases this improves performance by 15% + or so. + +USE_3DNOW_PREFETCH Causes the collector to issue AMD 3DNow style + prefetch instructions. Same restrictions as USE_I686_PREFETCH. + Minimally tested. Didn't appear to be an obvious win on a K6-2/500. + +USE_PPC_PREFETCH Causes the collector to issue PowerPC style + prefetch instructions. No effect except on PowerPC OS X platforms. + Performance impact untested. + +GC_USE_LD_WRAP In combination with the old flags listed in README.linux + causes the collector some system and pthread calls in a more transparent + fashion than the usual macro-based approach. Requires GNU ld, and + currently probably works only with Linux. + +GC_USE_DLOPEN_WRAP Causes the collector to redefine malloc and + intercepted pthread routines with their real names, and causes it to use + dlopen and dlsym to refer to the original versions. This makes it possible + to build an LD_PRELOADable malloc replacement library. + +THREAD_LOCAL_ALLOC Defines GC_malloc(), GC_malloc_atomic() and + GC_gcj_malloc() to use a per-thread set of free-lists. These then allocate + in a way that usually does not involve acquisition of a global lock. + Recommended for multiprocessors. + +USE_COMPILER_TLS Causes thread local allocation to use + the compiler-supported "__thread" thread-local variables. This is the + default in HP/UX. It may help performance on recent Linux installations. + (It failed for me on RedHat 8, but appears to work on RedHat 9.) + +GC_ATTR_TLS_FAST Use specific attributes for GC_thread_key like + __attribute__((tls_model("local-exec"))). + +PARALLEL_MARK Allows the marker to run in multiple threads. Recommended + for multiprocessors. + +GC_BUILTIN_ATOMIC Use GCC atomic intrinsics instead of libatomic_ops + primitives. + +GC_ALWAYS_MULTITHREADED Force multi-threaded mode at GC initialization. + +GC_ENABLE_SUSPEND_THREAD (Linux only) Turn on thread suspend/resume API +support. + +GC_WINMAIN_REDIRECT (Win32 only) Redirect (rename) an application + WinMain to GC_WinMain; implement the "real" WinMain which starts a new + thread to call GC_WinMain after initializing the GC. Useful for WinCE. + Incompatible with GC_DLL. + +GC_REGISTER_MEM_PRIVATE (Win32 only) Force to register MEM_PRIVATE R/W + sections as data roots. Might be needed for some WinCE 6.0+ custom builds. + (May result in numerous "Data Abort" messages logged to WinCE debugging + console.) Incompatible with GCC toolchains for WinCE. + +NO_GETENV Prevents the collector from looking at environment variables. + These may otherwise alter its configuration, or turn off GC altogether. + I don't know of a reason to disable this, except possibly if the resulting + process runs as a privileged user. (This is on by default for WinCE.) + +EMPTY_GETENV_RESULTS Define to workaround a reputed Wine bug in getenv + (getenv() may return an empty string instead of NULL for a missing entry). + +GC_READ_ENV_FILE (Win32 only) Read environment variables from the GC "env" + file (named as the program name plus ".gc.env" extension). Useful for WinCE + targets (which have no getenv()). In the file, every variable is specified + in a separate line and the format is as "=" (without spaces). + A comment line may start with any character except for the Latin letters, + the digits and the underscore ('_'). The file encoding is Latin-1. + +USE_GLOBAL_ALLOC (Win32 only) Use GlobalAlloc() instead of VirtualAlloc() + to allocate the heap. May be needed to work around a Windows NT/2000 issue. + Incompatible with USE_MUNMAP. See README.win32 for details. + +MAKE_BACK_GRAPH Enable GC_PRINT_BACK_HEIGHT environment variable. + See README.environment for details. Experimental. Limited platform + support. Implies DBG_HDRS_ALL. All allocation should be done using + the debug interface. + +GC_PRINT_BACK_HEIGHT Permanently turn on back-height printing mode + (useful when NO_GETENV). See the similar environment variable description + in README.environment. Requires MAKE_BACK_GRAPH defined. + +HANDLE_FORK (Unix and Cygwin only) Attempt by default to make GC_malloc() + work in a child process fork()'ed from a multi-threaded parent. Not fully + POSIX-compliant and could be disabled at runtime (before GC_INIT). + +TEST_WITH_SYSTEM_MALLOC Causes gctest to allocate (and leak) large + chunks of memory with the standard system malloc. This will cause the root + set and collected heap to grow significantly if malloc'ed memory is somehow + getting traced by the collector. This has no impact on the generated + library; it only affects the test. + +POINTER_MASK=<0x...> Causes candidate pointers to be AND'ed with the given + mask before being considered. If either this or the following macro is + defined, it will be assumed that all pointers stored in the heap need to be + processed this way. Stack and register pointers will be considered both + with and without processing. These macros are normally needed only to + support systems that use high-order pointer tags. EXPERIMENTAL. + +POINTER_SHIFT= Causes the collector to left shift candidate pointers + by the indicated amount before trying to interpret them. Applied after + POINTER_MASK. EXPERIMENTAL. See also the preceding macro. + +ENABLE_TRACE Enables the GC_TRACE=addr environment setting to do its job. + By default this is not supported in order to keep the marker as fast as + possible. + +DARWIN_DONT_PARSE_STACK Causes the Darwin port to discover thread + stack bounds in the same way as other pthread ports, without trying to + walk the frames on the stack. This is recommended only as a fall-back for + applications that don't support proper stack unwinding. + +GC_NO_THREADS_DISCOVERY (Darwin and Win32+DLL only) Exclude DllMain-based + (on Windows) and task-threads-based (on Darwin) thread registration support. + +GC_INSIDE_DLL (Win32 only) Enable DllMain-based approach of threads + registering even in case GC_DLL is not defined. + +GC_DISCOVER_TASK_THREADS (Darwin and Win32+DLL only) Compile the collector + with the implicitly turned on task-threads-based (on Darwin) or + DllMain-based (on Windows) approach of threads registering. Only for + compatibility and for the case when it is not possible to call + GC_use_threads_discovery() early (before other GC calls). + +USE_PROC_FOR_LIBRARIES Causes the Linux collector to treat writable + memory mappings (as reported by /proc) as roots, if it doesn't have + other information about them. It no longer traverses dynamic loader + data structures to find dynamic library static data. This may be + required for applications that store pointers in mmapped segments without + informing the collector. But it typically performs poorly, especially + since it will scan inactive but cached NPTL thread stacks completely. + +IGNORE_DYNAMIC_LOADING Don't define DYNAMIC_LOADING even if supported by the + platform (that is, build the collector with disabled tracing of dynamic + library data roots). + +NO_PROC_STAT Causes the collector to avoid relying on Linux + "/proc/self/stat". + +NO_GETCONTEXT Causes the collector to not assume the existence of the + getcontext() function on linux-like platforms. This currently happens + implicitly on Darwin, Hurd, or ARM or MIPS hardware. It is explicitly + needed for some old versions of FreeBSD. + +STATIC=static Causes various GC_ symbols that could logically be declared + static to be declared (this is the default if NO_DEBUGGING is specified). + Reduces the number of visible symbols (letting the optimizer do its work + better), which is probably cleaner, but may make some kinds of debugging + and profiling harder. + +GC_DLL Build dynamic-link library (or dynamic shared object). For Unix this + causes the exported symbols to have 'default' visibility (ignored unless + GCC v4+) and the internal ones to have 'hidden' visibility. + +NO_MSGBOX_ON_ERROR (Win32 only) Do not show Windows message box with + "OK" button on a GC fatal error. Otherwise the client application is + terminated only once the user clicks "OK" button. Useful for non-GUI (or + non-interactive) applications. + +DONT_USE_USER32_DLL (Win32 only) Don't use "user32" DLL import library + (containing MessageBox() entry); useful for a static GC library. + +GC_PREFER_MPROTECT_VDB Choose MPROTECT_VDB manually in case of multiple + virtual dirty bit strategies are implemented (at present useful on Win32, + Solaris and Linux to force MPROTECT_VDB strategy instead of the default + GWW_VDB, PROC_VDB or SOFT_VDB ones, respectively). + +GC_IGNORE_GCJ_INFO Disable GCJ-style type information (useful for + debugging on WinCE). + +GC_PRINT_VERBOSE_STATS Permanently turn on verbose logging (useful for + debugging and profiling on WinCE). + +GC_ONLY_LOG_TO_FILE Don't redirect GC stdout and stderr to the log file + specified by GC_LOG_FILE environment variable. Has effect only when the + variable is set (to anything other than "0"). + +GC_ANDROID_LOG (Android only) Output error/debug information to Android log. + +CONSOLE_LOG (Win32 only) Output error/debug information to stdout and + stderr. + +GC_DONT_EXPAND Don't expand the heap unless explicitly requested or forced to. + +GC_USE_ENTIRE_HEAP Causes the non-incremental collector to use the + entire heap before collecting. This sometimes results in more large block + fragmentation, since very large blocks will tend to get broken up during + each GC cycle. It is likely to result in a larger working set, but lower + collection frequencies, and hence fewer instructions executed in the + collector. This macro controls only the default GC_use_entire_heap value. + +GC_INITIAL_HEAP_SIZE= Set the desired default initial heap size + in bytes. + +GC_FREE_SPACE_DIVISOR= Set alternate default GC_free_space_divisor + value. + +GC_ALLOCD_BYTES_PER_FINALIZER= Set alternate default value of + GC_allocd_bytes_per_finalizer. + +GC_TIME_LIMIT= Set alternate default GC_time_limit value + (setting this to GC_TIME_UNLIMITED will essentially disable incremental + collection while leaving generational collection enabled). + +GC_FULL_FREQ= Set alternate default number of partial collections + between full collections (matters only if incremental collection is on). + +NO_CANCEL_SAFE (Posix platforms with threads only) Don't bother trying + to make the collector safe for thread cancellation; cancellation is not + used. (Note that if cancellation is used anyway, threads may end up + getting canceled in unexpected places.) Even without this option, + PTHREAD_CANCEL_ASYNCHRONOUS is never safe with the collector. (We could + argue about its safety without the collector.) + +UNICODE (Win32 only) Use the Unicode variant ('W') of the Win32 API instead + of ANSI/ASCII one ('A'). Useful for WinCE. + +HOST_ANDROID (or __ANDROID__) Compile for Android NDK platform. + +SN_TARGET_PS3 Compile for Sony PS/3. + +USE_GET_STACKBASE_FOR_MAIN (Linux only) Use pthread_attr_getstack() instead + of __libc_stack_end (or instead of any hard-coded value) for getting the + primordial thread stack bottom (useful if the client modifies the program's + address space). + +EMSCRIPTEN_ASYNCIFY (Emscripten only) Use Asyncify feature.

By default, the +collector chooses between explicit page protection, and GetWriteWatch-based +write tracking automatically, depending on the platform. + +The former is slow and interacts poorly with a debugger. +Pages are protected. Protection faults are caught by a handler +installed at the bottom of the handler +stack. Whenever possible, I recommend adding a call to +GC_enable_incremental at the last possible moment, after most +debugging is complete. No system +calls are wrapped by the collector itself. It may be necessary +to wrap ReadFile calls that use a buffer in the heap, so that the +call does not encounter a protection fault while it's running. +(As usual, none of this is an issue unless GC_enable_incremental +is called.) + +Note that incremental collection is disabled with -DSMALL_CONFIG. + +Threads +------- + +The collector by default handles threads similarly to other platforms. +James Clark's code which tracks threads attached to the collector DLL still +exists, but requires that both +- the collector is built in a DLL with GC_DLL defined, and +- GC_use_threads_discovery() is called before GC initialization, which + in turn must happen before creating additional threads. +We generally recommend avoiding this if possible, since it seems to +be less than 100% reliable. + +To build the collector as a dynamic library which handles threads similarly +to other platforms, type "nmake -f NT_MAKEFILE". If automatic tracking of +threads attached to the collector DLL (i.e. support of both kinds of thread +tracking) is needed then delete "-DTHREAD_LOCAL_ALLOC" from NT_MAKEFILE +manually before the build. + +The incremental collection is supported only if it is enabled before any +additional threads are created. + +Threads are also supported in static library builds with Microsoft tools +(e.g., NT_MAKEFILE), as well as with the CMake and GNU tools. The collector +must be built with GC_THREADS defined (this is the default in NT_MAKEFILE, +CMakeLists.txt and configure). + +For the normal, non-dll-based thread tracking to work properly, +threads should be created with GC_CreateThread or GC_beginthreadex, +and exit normally, or call GC_endthreadex or GC_ExitThread. (For Cygwin, the +standard pthread_create/exit calls could be used instead.) As in the pthread +case, including gc.h will redefine CreateThread, _beginthreadex, +_endthreadex, and ExitThread to call the GC_ versions instead. + +Note that, as usual, GC_CreateThread tends to introduce resource leaks (in the +C runtime) that are avoided by GC_beginthreadex.

The collector installs handlers to take care +of these. You will not see these unless you are using a debugger. Your +debugger _should_ allow you to continue. It's often preferable to tell the +debugger to ignore SIGBUS and SIGSEGV ("handle SIGSEGV SIGBUS nostop noprint" +in gdb, "ignore SIGSEGV SIGBUS" in most versions of dbx) and set a breakpoint +in `abort`.

See README.win32.) + +If the application generates an unhandled SIGSEGV or equivalent, it may often +be easiest to set the environment variable `GC_LOOP_ON_ABORT`.

These false pointers can be either permanent (e.g. +a static integer variable that never changes) or temporary. In the latter +case, the warning is largely spurious, and the block will eventually +be reclaimed normally. In the former case, the program will still run +correctly, but the block will never be reclaimed. Unless the block is intended +to be permanent, the warning indicates a memory leak. + + 1. Ignore these warnings while you are using GC_DEBUG. Some of the routines + mentioned below don't have debugging equivalents. (Alternatively, write the + missing routines and send them to me.) + 2. Replace allocator calls that request large blocks with calls to + `GC_malloc_ignore_off_page` or `GC_malloc_atomic_ignore_off_page`. You may + want to set a breakpoint in `GC_default_warn_proc` to help you identify such + calls. Make sure that a pointer to somewhere near the beginning of the + resulting block is maintained in a (preferably volatile) variable as long + as the block is needed. + 3. If the large blocks are allocated with realloc, we suggest instead + allocating them with something like the following. Note that the realloc + size increment should be fairly large (e.g. a factor of 3/2) for this to + exhibit reasonable performance. But we all know we should do that anyway. + + + void * big_realloc(void *p, size_t new_size) { + size_t old_size = GC_size(p); + void * result; + if (new_size <= 10000) return(GC_realloc(p, new_size)); + if (new_size <= old_size) return(p); + result = GC_malloc_ignore_off_page(new_size); + if (result == 0) return(0); + memcpy(result,p,old_size); + GC_free(p); + return(result); + } + + + 4. In the unlikely case that even relatively small object (<20 KB) + allocations are triggering these warnings, then your address space contains + lots of "bogus pointers", i.e. values that appear to be pointers but aren't. + Usually this can be solved by using `GC_malloc_atomic` or the routines + in `gc_typed.h` to allocate large pointer-free regions of bitmaps, etc. + Sometimes the problem can be solved with trivial changes of encoding + in certain values. It is possible, to identify the source of the bogus + pointers by building the collector with `-DPRINT_BLACK_LIST`, which will + cause it to print the "bogus pointers", along with their location. + 5. If you get only a fixed number of these warnings, you are probably only + introducing a bounded leak by ignoring them. If the data structures being + allocated are intended to be permanent, then it is also safe to ignore them. + The warnings can be turned off by calling `GC_set_warn_proc` with + a procedure that ignores these warnings (e.g. by doing absolutely nothing). + +## The Collector References a Bad Address in GC_malloc + +This typically happens while the collector is trying to remove an entry from +its free list, and the free list pointer is bad because the free list link +in the last allocated object was bad. + +With >99% probability, you wrote past the end of an allocated object. Try +setting `GC_DEBUG` before including `gc.h` and allocating with `GC_MALLOC`. +This will try to detect such overwrite errors. + +## Unexpectedly Large Heap + +Unexpected heap growth can be due to one of the following: + + 1. Data structures that are being unintentionally retained. This is commonly + caused by data structures that are no longer being used, but were not + cleared, or by caches growing without bounds. + 2. Pointer misidentification. The garbage collector is interpreting integers + or other data as pointers and retaining the "referenced" objects. A common + symptom is that GC_dump() shows much of the heap as black-listed. + 3. Heap fragmentation. This should never result in unbounded growth, but + it may account for larger heaps. This is most commonly caused by allocation + of large objects. + 4. Per object overhead. This is usually a relatively minor effect, but + it may be worth considering. If the collector recognizes interior pointers, + object sizes are increased, so that one-past-the-end pointers are correctly + recognized. The collector can be configured not to do this + (`-DDONT_ADD_BYTE_AT_END`). + +The collector rounds up object sizes so the result fits well into the chunk +size (`HBLKSIZE`, normally 4 KB on 32-bit machines, 8 KB on 64-bit ones) used +by the collector. Thus it may be worth avoiding objects of size 2K + 1 bytes +(or exactly 2 KB if a byte is being added at the end.) The last two cases can +often be identified by looking at the output of a call to `GC_dump`. Among +other things, it will print the list of free heap blocks, and a very brief +description of all chunks in the heap, the object sizes they correspond to, +and how many live objects were found in the chunk at the last collection. + +Growing data structures can usually be identified by: + + 1. Building the collector with `-DKEEP_BACK_PTRS`, + 2. Preferably using debugging allocation (defining `GC_DEBUG` before + including `gc.h` and allocating with `GC_MALLOC`), so that objects will + be identified by their allocation site, + 3. Running the application long enough so that most of the heap is composed + of "leaked" memory, and + 4. Then calling `GC_generate_random_backtrace` from gc_backptr.h a few times + to determine why some randomly sampled objects in the heap are being + retained. + +The same technique can often be used to identify problems with false pointers, +by noting whether the reference chains printed +by `GC_generate_random_backtrace` involve any misidentified pointers. +An alternate technique is to build the collector with `-DPRINT_BLACK_LIST` +which will cause it to report values that are almost, but not quite, look like +heap pointers. It is very likely that actual false pointers will come from +similar sources. + +In the unlikely case that false pointers are an issue, it can usually +be resolved using one or more of the following techniques: + + 1. Use `GC_malloc_atomic` for objects containing no pointers. This is + especially important for large arrays containing compressed data, + pseudo-random numbers, and the like. It is also likely to improve GC + performance, perhaps drastically so if the application is paging. + 2. If you allocate large objects containing only one or two pointers at the + beginning, either try the typed allocation primitives in `gc_typed.h`, + or separate out the pointer-free component. + 3. Consider using `GC_malloc_ignore_off_page` to allocate large objects. + (See `gc.h` and above for details. Large means more than 100 KB in most + environments.) + 4. If your heap size is larger than 100 MB or so, build the collector with + `-DLARGE_CONFIG`. This allows the collector to keep more precise black-list + information. + 5. If you are using heaps close to, or larger than, a gigabyte on a 32-bit + machine, you may want to consider moving to a platform with 64-bit pointers. + This is very likely to resolve any false pointer issues. + +## Prematurely Reclaimed Objects + +The usual symptom of this is a segmentation fault, or an obviously overwritten +value in a heap object. This should, of course, be impossible. In practice, +it may happen for reasons like the following: + + 1. The collector did not intercept the creation of threads correctly + in a multi-threaded application, e.g. because the client called + `pthread_create` without including `gc.h`, which redefines it. + 2. The last pointer to an object in the garbage collected heap was stored + somewhere were the collector could not see it, e.g. in an object allocated + with system `malloc`, in certain types of `mmap`ed files, or in some data + structure visible only to the OS. (On some platforms, thread-local storage + is one of these.) + 3. The last pointer to an object was somehow disguised, e.g. by XORing + it with another pointer. + 4. Incorrect use of `GC_malloc_atomic` or typed allocation. + 5. An incorrect `GC_free` call. + 6. The client program overwrote an internal garbage collector data + structure. + 7. A garbage collector bug. + 8. (Empirically less likely than any of the above.) A compiler optimization + that disguised the last pointer. + +The following relatively simple techniques should be tried first to narrow +down the problem: + + 1. If you are using the incremental collector try turning it off for + debugging. + 2. If you are using shared libraries, try linking statically. If that works, + ensure that DYNAMIC_LOADING is defined on your platform. + 3. Try to reproduce the problem with fully debuggable unoptimized code. This + will eliminate the last possibility, as well as making debugging easier. + 4. Try replacing any suspect typed allocation and `GC_malloc_atomic` calls + with calls to `GC_malloc`. + 5. Try removing any `GC_free` calls (e.g. with a suitable `#define`). + 6. Rebuild the collector with `-DGC_ASSERTIONS`. + 7. If the following works on your platform (i.e. if gctest still works if + you do this), try building the collector with + `-DREDIRECT_MALLOC=GC_malloc_uncollectable`. This will cause the collector + to scan memory allocated with malloc. + +If all else fails, you will have to attack this with a debugger. The suggested +steps are: + + 1. Call `GC_dump` from the debugger around the time of the failure. Verify + that the collectors idea of the root set (i.e. static data regions which + it should scan for pointers) looks plausible. If not, i.e. if it does not + include some static variables, report this as a collector bug. Be sure + to describe your platform precisely, since this sort of problem is nearly + always very platform dependent. + 2. Especially if the failure is not deterministic, try to isolate + it to a relatively small test case. + 3. Set a break point in `GC_finish_collection`. This is a good point + to examine what has been marked, i.e. found reachable, by the collector. + 4. If the failure is deterministic, run the process up to the last + collection before the failure. Note that the variable `GC_gc_no` counts + collections and can be used to set a conditional breakpoint in the right + one. It is incremented just before the call to `GC_finish_collection`. + If object `p` was prematurely recycled, it may be helpful to look + at `*GC_find_header(p)` at the failure point. The `hb_last_reclaimed` field + will identify the collection number during which its block was last swept. + 5. Verify that the offending object still has its correct contents at this + point. Then call `GC_is_marked(p)` from the debugger to verify that the + object has not been marked, and is about to be reclaimed. Note that + `GC_is_marked(p)` expects the real address of an object (the address of the + debug header if there is one), and thus it may be more appropriate to call + `GC_is_marked(GC_base(p))` instead. + 6. Determine a path from a root, i.e. static variable, stack, or register + variable, to the reclaimed object. Call `GC_is_marked(q)` for each object + `q` along the path, trying to locate the first unmarked object, say `r`. + 7. If `r` is pointed to by a static root, verify that the location pointing + to it is part of the root set printed by `GC_dump`. If it is on the stack + in the main (or only) thread, verify that `GC_stackbottom` is set correctly + to the base of the stack. If it is in another thread stack, check the + collector's thread data structure (`GC_thread[]` on several platforms) + to make sure that stack bounds are set correctly. + 8. If `r` is pointed to by heap object `s`, check that the collector's + layout description for `s` is such that the pointer field will be scanned. + Call `*GC_find_header(s)` to look at the descriptor for the heap chunk. + The `hb_descr` field specifies the layout of objects in that chunk. + See `gc_mark.h` for the meaning of the descriptor. (If its low order 2 bits + are zero, then it is just the length of the object prefix to be scanned. + This form is always used for objects allocated with `GC_malloc` or + `GC_malloc_atomic`.) + 9. If the failure is not deterministic, you may still be able to apply some + of the above technique at the point of failure. But remember that objects + allocated since the last collection will not have been marked, even if the + collector is functioning properly. On some platforms, the collector can + be configured to save call chains in objects for debugging. Enabling this + feature will also cause it to save the call stack at the point of the last + GC in `GC_arrays._last_stack`. + 10. When looking at GC internal data structures remember that a number + of `GC_xxx` variables are really macro defined to `GC_arrays._xxx`, so that + the collector can avoid scanning them. diff --git a/graphics/asymptote/gc/doc/doc.am b/graphics/asymptote/gc/doc/doc.am new file mode 100644 index 0000000000..39322f94a4 --- /dev/null +++ b/graphics/asymptote/gc/doc/doc.am @@ -0,0 +1,52 @@ +# +# THIS MATERIAL IS PROVIDED AS IS, WITH ABSOLUTELY NO WARRANTY EXPRESSED +# OR IMPLIED.

This can be used to reclaim any system resources +or non-garbage-collected memory associated with the object. Experience has +shown that this can be a useful facility. It is indispensable in cases +in which system resources are embedded in complex data structures (e.g. file +descriptors in the `include/cord.h`). + +Our collector provides the necessary functionality through +`GC_register_finalizer` in `include/gc.h`, or by inheriting from `gc_cleanup` +in `include/gc_cpp.h`). + +However, finalization should not be used in the same way as C++ destructors. +In well-written programs there will typically be very few uses +of finalization. (Garbage collected programs that interact with explicitly +memory-managed libraries may be an exception.) + +In general the following guidelines should be followed: + + * Actions that must be executed promptly do not belong in finalizers.

If you expect the action to occur at a specific point, this + is probably not hard. + * Finalizers are intended for resource reclamation. + * Scarce system resources should be managed explicitly whenever convenient. + Use finalizers only as a backup mechanism for the cases that would be hard + to handle explicitly. + * If scarce resources are managed with finalization, the allocation routine + for that resource (e.g. open for file handles) should force a garbage + collection (two if that does not suffice) if it finds itself short of the + resource. + * If extremely scarce resources are managed by finalization (e.g. file + descriptors on systems which have a limit of 20 open files), it may + be necessary to introduce a descriptor caching scheme to hide the resource + limit. (E.g., the program would keep real file descriptors for the 20 most + recently used logically open files. Any other needed files would be closed + after saving their state. They would then be reopened on demand. + Finalization would logically close the file, closing the real descriptor + only if it happened to be cached.) Note that most modern systems allow + thousands of open files, and this is typically not an issue. + * Finalization code may be run anyplace an allocation or other call to the + collector takes place. In multi-threaded programs, finalizers have to obey + the normal locking conventions to ensure safety. Code run directly from + finalizers should not acquire locks that may be held during allocation. + This restriction can be easily circumvented by calling + `GC_set_finalize_on_demand(1)` at program start and creating a separate + thread dedicated to periodic invocation of `GC_invoke_finalizers()`. + +In single-threaded code, it is also often easiest to have finalizers queued +and, then to have them explicitly executed by `GC_invoke_finalizers()`. + +## Topologically ordered finalization + +Our _conservative garbage collector_ supports a form of finalization (with +`GC_register_finalizer`) in which objects are finalized in topological order. +If _A_ points to _B_ and both are registered for finalization, it is +guaranteed the _A_ will be finalized first. This usually guarantees that +finalization procedures see only unfinalized objects. + +This decision is often questioned, particularly since it has an obvious +disadvantage. The current implementation finalizes long chains of finalizable +objects one per collection. This is hard to avoid, since the first finalizer +invoked may store a pointer to the rest of the chain in a global variable, +making it accessible again. Or it may mutate the rest of the chain. + +Cycles involving one or more finalizable objects are never finalized. + +## Why topological ordering? + +It is important to keep in mind that the choice of finalization ordering +matters only in relatively rare cases. In spite of the fact that it has +received a lot of discussion, it is not one of the more important decisions +in designing a system. Many, especially smaller, applications will never +notice the difference. Nonetheless, we believe that topologically ordered +finalization is the right choice. + +To understand the justification, observe that if _A_'s finalization procedure +does not refer to _B_, we could fairly easily have avoided the dependency. +We could have split _A_ into _A'_ and _A''_ such that any references to _A_ +become references to _A'_, _A'_ points to _A''_ but not vice-versa, only +fields needed for finalization are stored in _A''_, and _A''_ is enabled for +finalization. (`GC_register_disappearing_link` provides an alternative +mechanism that does not require breaking up objects.) + +Thus assume that _A_ actually does need access to _B_ during finalization. +To make things concrete, assume that _B_ is finalizable because it holds +a pointer to a C object, which must be explicitly deallocated. (This is likely +to be one of the most common uses of finalization.) If _B_ happens to be +finalized first, _A_ will see a dangling pointer during its finalization. But +a principal goal of garbage collection was to avoid dangling pointers. + +Note that the client program could enforce topological ordering even if the +system did not. A pointer to _B_ could be stored in some globally visible +place, where it is cleared only by _A_'s finalizer. But this puts the burden +to ensure safety back on the programmer. + +With topologically ordered finalization, the programmer can fail to split +an object, thus leaving an accidental cycle. This results in a leak, which +is arguably less dangerous than a dangling pointer. More importantly, it is +_much_ easier to diagnose, since the garbage collector would have to go out of +its way not to notice finalization cycles. It can trivially report them. + +Furthermore unordered finalization does not really solve the problem +of cycles. Consider the above case in which _A_'s finalization procedure +depends on _B_, and thus a pointer to _B_ is stored in a global data +structure, to be cleared by _A_'s finalizer. If there is an accidental pointer +from _B_ back to _A_, and thus a cycle, neither _B_ nor _A_ will become +unreachable. The leak is there, just as in the topologically ordered case, but +it is hidden from easy diagnosis. + +A number of alternative finalization orderings have been proposed, e.g. based +on statically assigned priorities. In our opinion, these are much more likely +to require complex programming discipline to use in a large modular system. +(Some of them, e.g. Guardians proposed by Dybvig, Bruggeman, and Eby, do avoid +some problems which arise in combination with certain other collection +algorithms.) + +Fundamentally, a garbage collector assumes that objects reachable via pointer +chains may be accessed, and thus should be preserved. Topologically ordered +finalization simply extends this to object finalization; an finalizable object +reachable from another finalizer via a pointer chain is presumed to be +accessible by the finalizer, and thus should not be finalized. + +## Programming with topological finalization + +Experience with Cedar has shown that cycles or long chains of finalizable +objects are typically not a problem. Finalizable objects are typically rare. +There are several ways to reduce spurious dependencies between finalizable +objects. Splitting objects as discussed above is one technique. The collector +also provides `GC_register_disappearing_link`, which explicitly nils a pointer +before determining finalization ordering. + +Some so-called "operating systems" fail to clean up some resources associated +with a process. These resources must be deallocated at all cost before process +exit whether or not they are still referenced. Probably the best way to deal +with those is by not relying exclusively on finalization. They should +be registered in a table of weak pointers (implemented as disguised pointers +cleared by the finalization procedure that deallocates the resource). If any +references are still left at process exit, they can be explicitly deallocated +then. + +## Getting around topological finalization ordering + +There are certain situations in which cycles between finalizable objects are +genuinely unavoidable. Most notably, C++ compilers introduce self-cycles +to represent inheritance. `GC_register_finalizer_ignore_self` tells the +finalization part of the collector to ignore self cycles. This is used by the +C++ interface. + +Finalize.c actually contains an intentionally undocumented mechanism for +registering a finalizable object with user-defined dependencies. The problem +is that this dependency information is also used for memory reclamation, not +just finalization ordering. Thus misuse can result in dangling pointers even +if finalization does not create any. The risk of dangling pointers can be +eliminated by building the collector with `-DJAVA_FINALIZATION`. This forces +objects reachable from finalizers to be marked, even though this dependency +is not considered for finalization ordering. diff --git a/graphics/asymptote/gc/doc/gc.man b/graphics/asymptote/gc/doc/gc.man new file mode 100644 index 0000000000..86065b52c9 --- /dev/null +++ b/graphics/asymptote/gc/doc/gc.man @@ -0,0 +1,155 @@ +.TH BDWGC 3 "23 Aug 2023" +.SH NAME +GC_malloc, GC_malloc_atomic, GC_free, GC_realloc, GC_enable_incremental, +GC_register_finalizer, GC_malloc_ignore_off_page, +GC_malloc_atomic_ignore_off_page, GC_set_warn_proc \- Garbage collecting +malloc replacement +.SH SYNOPSIS +#include +.br +void * GC_malloc(size_t size); +.br +void * GC_malloc_atomic(size_t size); +.br +void GC_free(void *ptr); +.br +void * GC_realloc(void *ptr, size_t size); +.br +void GC_enable_incremental(void); +.br +void * GC_malloc_ignore_off_page(size_t size); +.br +void * GC_malloc_atomic_ignore_off_page(size_t size); +.br +void GC_set_warn_proc(void (*proc)(char *, GC_word)); +.br +.sp +cc ... -lgc +.LP +.SH DESCRIPTION +.I GC_malloc +and +.I GC_free +are plug-in replacements for standard malloc and free.

Conceptually +it operates roughly in four phases, which are performed occasionally as part +of a memory allocation: + + 1. _Preparation phase_ + + Each object has an associated mark bit. Clear all mark + bits, indicating that all objects are potentially unreachable. + + 2. _Mark phase_ + + Marks all objects that can be reachable via chains of pointers from + variables. Often the collector has no real information about the location + of pointer variables in the heap, so it views all static data areas, + stacks and registers as potentially containing pointers. Any bit + patterns that represent addresses inside heap objects managed by the + collector are viewed as pointers. Unless the client program has made heap + object layout information available to the collector, any heap objects + found to be reachable from variables are again scanned similarly. + + 3. _Sweep phase_ + + Scans the heap for inaccessible, and hence unmarked, + objects, and returns them to an appropriate free list for reuse. This is + not really a separate phase; even in non-incremental mode this operation + is usually performed on demand during an allocation that discovers an + empty free list. Thus the sweep phase is very unlikely to touch a page + that would not have been touched shortly thereafter anyway. + + 4. _Finalization phase_ + + Unreachable objects which had been registered for + finalization are enqueued for finalization outside the collector. + +The remaining sections describe the memory allocation data structures, and +then the last 3 collection phases in more detail. We conclude by outlining +some of the additional features implemented in the collector. + +## Allocation + +The collector includes its own memory allocator. The allocator obtains memory +from the system in a platform-dependent way. Under UNIX, it uses either +`malloc`, `sbrk`, or `mmap`. + +Most static data used by the allocator, as well as that needed by the rest +of the garbage collector is stored inside the `_GC_arrays` structure. This +allows the garbage collector to easily ignore the collectors own data +structures when it searches for root pointers. Other allocator and collector +internal data structures are allocated dynamically with `GC_scratch_alloc`. +The latter does not allow for deallocation, and is therefore used only for +permanent data structures. + +The allocator returns objects of different _kinds_. Different _kinds_ are +handled somewhat differently by certain parts of the garbage collector. +Certain kinds are scanned for pointers, others are not. Some may have +per-object type descriptors that determine pointer locations. Or a specific +kind may correspond to one specific object layout. Two built-in kinds are +uncollectible. In spite of that, it is very likely that most C clients of the +collector currently use at most two kinds: `NORMAL` and `PTRFREE` objects. The +[GCJ](https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcj/) runtime also makes heavy +use of a kind (allocated with `GC_gcj_malloc`) that stores type information +at a known offset in method tables. + +The collector uses a two level allocator. A large block is defined to be one +larger than half of `HBLKSIZE`, which is a power of 2, typically on the order +of the page size. + +Large block sizes are rounded up to the next multiple of `HBLKSIZE` and then +allocated by `GC_allochblk`. The collector use an approximate best fit +algorithm by keeping free lists for several large block sizes. The actual +implementation of `GC_allochblk` is significantly complicated by black-listing +issues (see below). + +Small blocks are allocated in chunks of size `HBLKSIZE`. Each chunk +is dedicated to only one object size and kind. + +The allocator maintains separate free lists for each size and kind of object. +Associated with each kind is an array of free list pointers, with entry +`freelist[i]` pointing to a free list of size 'i' objects. Index `i` is +expressed in granules, which are the minimum allocatable unit, typically 8 or +16 bytes. The free lists themselves are linked through the first word in each +object (see `obj_link` macro). + +Once a large block is split for use in smaller objects, it can only be used +for objects of that size, unless the collector discovers a completely empty +chunk. Completely empty chunks are restored to the appropriate large block +free list. + +In order to avoid allocating blocks for too many distinct object sizes, the +collector normally does not directly allocate objects of every possible +request size. Instead, the request is rounded up to one of a smaller number +of allocated sizes, for which free lists are maintained. The exact allocated +sizes are computed on demand, but subject to the constraint that they increase +roughly in geometric progression. Thus objects requested early in the +execution are likely to be allocated with exactly the requested size, subject +to alignment constraints. See `GC_init_size_map` for details. + +The actual size rounding operation during small object allocation +is implemented as a table lookup in `GC_size_map` which maps a requested +allocation size in bytes to a number of granules. + +Both collector initialization and computation of allocated sizes are handled +carefully so that they do not slow down the small object fast allocation path. +An attempt to allocate before the collector is initialized, or before the +appropriate `GC_size_map` entry is computed, will take the same path as an +allocation attempt with an empty free list. This results in a call to the slow +path code (`GC_generic_malloc_inner`) which performs the appropriate +initialization checks. + +In non-incremental mode, we make a decision about whether to garbage collect +whenever an allocation would otherwise have failed with the current heap size. +If the total amount of allocation since the last collection is less than the +heap size divided by `GC_free_space_divisor`, we try to expand the heap. +Otherwise, we initiate a garbage collection. This ensures that the amount +of garbage collection work per allocated byte remains constant. + +The above is in fact an oversimplification of the real heap expansion and GC +triggering heuristic, which adjusts slightly for root size and certain kinds +of fragmentation. In particular: + + * Programs with a large root set size and little live heap memory will + expand the heap to amortize the cost of scanning the roots. + * GC actually collects more frequently in non-incremental mode. The large + block allocator usually refuses to split large heap blocks once the garbage + collection threshold is reached. This often has the effect of collecting + well before the heap fills up, thus reducing fragmentation and working set + size at the expense of GC time. (If the collector is configured not to unmap + unused pages, GC chooses an intermediate strategy depending on how much + large object allocation has taken place in the past.) + * In calculating the amount of allocation since the last collection we give + partial credit for objects we expect to be explicitly deallocated. Even + if all objects are explicitly managed, it is often desirable to collect + on rare occasion, since that is our only mechanism for coalescing completely + empty chunks. + +It has been suggested that this should be adjusted so that we favor expansion +if the resulting heap still fits into physical memory. In many cases, that +would no doubt help. But it is tricky to do this in a way that remains robust +if multiple application are contending for a single pool of physical memory. + +## Mark phase + +At each collection, the collector marks all objects that are possibly +reachable from pointer variables. Since it cannot generally tell where pointer +variables are located, it scans the following _root segments_ for pointers: + + * The registers. Depending on the architecture, this may be done using + assembly code, or by calling a `setjmp`-like function which saves register + contents on the stack. + * The stack(s). In the case of a single-threaded application, on most + platforms this is done by scanning the memory between (an approximation of) + the current stack pointer and `GC_stackbottom`. (For Intel Itanium, the + register stack scanned separately.) The `GC_stackbottom` variable is set in + a highly platform-specific way depending on the appropriate configuration + information in `gcconfig.h`. Note that the currently active stack needs + to be scanned carefully, since callee-save registers of client code may + appear inside collector stack frames, which may change during the mark + process. This is addressed by scanning some sections of the stack _eagerly_, + effectively capturing a snapshot at one point in time. + * Static data region(s). In the simplest case, this is the region between + `DATASTART` and `DATAEND`, as defined in `gcconfig.h`. However, in most + cases, this will also involve static data regions associated with dynamic + libraries. These are identified by the mostly platform-specific code + in `dyn_load.c`. The marker maintains an explicit stack of memory regions + that are known to be accessible, but that have not yet been searched for + contained pointers. Each stack entry contains the starting address of the + block to be scanned, as well as a descriptor of the block. If no layout + information is available for the block, then the descriptor is simply + a length. (For other possibilities, see `gc_mark.h`.) + +At the beginning of the mark phase, all root segments (as described above) are +pushed on the stack by `GC_push_roots`. (Registers and eagerly scanned stack +sections are processed by pushing the referenced objects instead of the stack +section itself.) If `ALL_INTERIOR_POINTERS` is not defined, then stack roots +require special treatment. In this case, the normal marking code ignores +interior pointers, but `GC_push_all_stack` explicitly checks for interior +pointers and pushes descriptors for target objects. + +The marker is structured to allow incremental marking. Each call +to `GC_mark_some` performs a small amount of work towards marking the heap. +It maintains explicit state in the form of `GC_mark_state`, which identifies +a particular sub-phase. Some other pieces of state, most notably the mark +stack, identify how much work remains to be done in each sub-phase. The normal +progression of mark states for a stop-the-world collection is: + + 1. `MS_INVALID` indicating that there may be accessible unmarked objects. + In this case `GC_objects_are_marked` will simultaneously be false, so the + mark state is advanced to + 2. `MS_PUSH_UNCOLLECTABLE` indicating that it suffices to push uncollectible + objects, roots, and then mark everything reachable from them. `GC_scan_ptr` + is advanced through the heap until all uncollectible objects are pushed, and + objects reachable from them are marked. At that point, the next call + to `GC_mark_some` calls `GC_push_roots` to push the roots. It, then, + advances the mark state to + 3. `MS_ROOTS_PUSHED` asserting that once the mark stack is empty, all + reachable objects are marked. Once in this state, we work only on emptying + the mark stack. Once this is completed, the state changes to + 4. `MS_NONE` indicating that reachable objects are marked. + +The core mark routine `GC_mark_from`, is called repeatedly by several of the +sub-phases when the mark stack starts to fill up. It is also called repeatedly +in `MS_ROOTS_PUSHED` state to empty the mark stack. The routine is designed +to only perform a limited amount of marking at each call, so that it can +also be used by the incremental collector. It is fairly carefully tuned, +since it usually consumes a large majority of the garbage collection time. + +The fact that it performs only a small amount of work per call also allows +it to be used as the core routine of the parallel marker. In that case it is +normally invoked on thread-private mark stacks instead of the global mark +stack. More details can be found [here](scale.md). + +The marker correctly handles mark stack overflows. Whenever the mark stack +overflows, the mark state is reset to `MS_INVALID`. Since there are already +marked objects in the heap, this eventually forces a complete scan of the +heap, searching for pointers, during which any unmarked objects referenced +by marked objects are again pushed on the mark stack. This process is repeated +until the mark phase completes without a stack overflow. Each time the stack +overflows, an attempt is made to grow the mark stack. All pieces of the +collector that push regions onto the mark stack have to be careful to ensure +forward progress, even in case of repeated mark stack overflows. Every mark +attempt results in additional marked objects. + +Each mark stack entry is processed by examining all candidate pointers in the +range described by the entry. If the region has no associated type information +then this typically requires that each 4-byte aligned quantity (8-byte aligned +if 64-bit pointers) be considered a candidate pointer. + +We determine whether a candidate pointer is actually the address of a heap +block. This is done in the following steps: + + * The candidate pointer is checked against rough heap bounds. These heap + bounds are maintained such that all actual heap objects fall between them. + In order to facilitate black-listing (see below) we also include address + regions that the heap is likely to expand into. Most non-pointers fail this + initial test. + * The candidate pointer is divided into two pieces; the most significant + bits identify a `HBLKSIZE`-sized page in the address space, and the least + significant bits specify an offset within that page. (A hardware page may + actually consist of multiple such pages. Normally, HBLKSIZE is usually the + page size divided by a small power of two. Alternatively, if the collector + is built with `-DLARGE_CONFIG`, such a page may consist of multiple hardware + pages.) + * The page address part of the candidate pointer is looked up in + a [table](tree.md). Each table entry contains either 0, indicating that + the page is not part of the garbage collected heap, a small integer _n_, + indicating that the page is part of large object, starting at least _n_ + pages back, or a pointer to a descriptor for the page. In the first case, + the candidate pointer is not a true pointer and can be safely ignored. + In the last two cases, we can obtain a descriptor for the page containing + the beginning of the object. + * The starting address of the referenced object is computed. The page + descriptor contains the size of the object(s) in that page, the object kind, + and the necessary mark bits for those objects. The size information can be + used to map the candidate pointer to the object starting address. + To accelerate this process, the page header also contains a pointer to + a precomputed map of page offsets to displacements from the beginning of an + object. The use of this map avoids a potentially slow integer remainder + operation in computing the object start address. + * The mark bit for the target object is checked and set. If the object was + previously unmarked, the object is pushed on the mark stack. The descriptor + is read from the page descriptor. (This is computed from information stored + in `GC_obj_kinds` when the page is first allocated.) + +At the end of the mark phase, mark bits for left-over free lists are cleared, +in case a free list was accidentally marked due to a stray pointer. + +## Sweep phase + +At the end of the mark phase, all blocks in the heap are examined. Unmarked +large objects are immediately returned to the large object free list. Each +small object page is checked to see if all mark bits are clear. If so, the +entire page is returned to the large object free list. Small object pages +containing some reachable object are queued for later sweeping, unless +we determine that the page contains very little free space, in which case +it is not examined further. + +This initial sweep pass touches only block headers, not the blocks themselves. +Thus it does not require significant paging, even if large sections of the +heap are not in physical memory. + +Nonempty small object pages are swept when an allocation attempt encounters +an empty free list for that object size and kind. Pages for the correct size +and kind are repeatedly swept until at least one empty block is found. +Sweeping such a page involves scanning the mark bit array in the page header, +and building a free list linked through the first words in the objects +themselves. This does involve touching the appropriate data page, but in most +cases it will be touched only just before it is used for allocation. Hence any +paging is essentially unavoidable. + +Except in the case of pointer-free objects, we maintain the invariant that any +object in a small object free list is cleared (except possibly for the link +field). Thus it becomes the burden of the small object sweep routine to clear +objects. This has the advantage that we can easily recover from accidentally +marking a free list, though that could also be handled by other means. The +collector currently spends a fair amount of time clearing objects, and this +approach should probably be revisited. In most configurations, we use +specialized sweep routines to handle common small object sizes. Since +we allocate one mark bit per word, it becomes easier to examine the relevant +mark bits if the object size divides the word length evenly. We also suitably +unroll the inner sweep loop in each case. (It is conceivable that +profile-based procedure cloning in the compiler could make this unnecessary +and counterproductive. I know of no existing compiler to which this applies.) + +The sweeping of small object pages could be avoided completely at the expense +of examining mark bits directly in the allocator. This would probably be more +expensive, since each allocation call would have to reload a large amount +of state (e.g. next object address to be swept, position in mark bit table) +before it could do its work. The current scheme keeps the allocator simple and +allows useful optimizations in the sweeper. + +## Finalization + +Both `GC_register_disappearing_link` and `GC_register_finalizer` add the +request to a corresponding hash table. The hash table is allocated out of +collected memory, but the reference to the finalizable object is hidden from +the collector. Currently finalization requests are processed non-incrementally +at the end of a mark cycle. + +The collector makes an initial pass over the table of finalizable objects, +pushing the contents of unmarked objects onto the mark stack. After pushing +each object, the marker is invoked to mark all objects reachable from it. The +object itself is not explicitly marked. This assures that objects on which +a finalizer depends are neither collected nor finalized. + +If in the process of marking from an object the object itself becomes marked, +we have uncovered a cycle involving the object. This usually results in +a warning from the collector. Such objects are not finalized, since it may be +unsafe to do so. See the more detailed discussion of +[finalization semantics](finalization.md). + +Any objects remaining unmarked at the end of this process are added to a queue +of objects whose finalizers can be run. Depending on collector configuration, +finalizers are dequeued and run either implicitly during allocation calls, +or explicitly in response to a user request. (Note that the former +is unfortunately both the default and not generally safe. If finalizers +perform synchronization, it may result in deadlocks. Nontrivial finalizers +generally need to perform synchronization, and thus require a different +collector configuration.) + +The collector provides a mechanism for replacing the procedure that is used +to mark through objects. This is used both to provide support for Java-style +unordered finalization, and to ignore certain kinds of cycles, e.g. those +arising from C++ implementations of virtual inheritance. + +## Generational Collection and Dirty Bits + +We basically use the concurrent and generational GC algorithm described in +["Mostly Parallel Garbage Collection"](http://www.hboehm.info/gc/papers/pldi91.ps.Z), +by Boehm, Demers, and Shenker. + +The most significant modification is that the collector always starts running +in the allocating thread. There is no separate garbage collector thread. (If +parallel GC is enabled, helper threads may also be woken up.) If an allocation +attempt either requests a large object, or encounters an empty small object +free list, and notices that there is a collection in progress, it immediately +performs a small amount of marking work as described above. + +This change was made both because we wanted to easily accommodate +single-threaded environments, and because a separate GC thread requires very +careful control over the scheduler to prevent the mutator from out-running the +collector, and hence provoking unneeded heap growth. + +In incremental mode, the heap is always expanded when we encounter +insufficient space for an allocation. Garbage collection is triggered whenever +we notice that more than `GC_heap_size / 2 * GC_free_space_divisor` bytes +of allocation have taken place. After `GC_full_freq` minor collections a major +collection is started. + +All collections initially run uninterrupted until a predetermined amount +of time (50 ms by default) has expired. If this allows the collection +to complete entirely, we can avoid correcting for data structure modifications +during the collection. If it does not complete, we return control to the +mutator, and perform small amounts of additional GC work during those later +allocations that cannot be satisfied from small object free lists. When +marking completes, the set of modified pages is retrieved, and we mark once +again from marked objects on those pages, this time with the mutator stopped. + +We keep track of modified pages using one of several distinct mechanisms: + + * (`MPROTECT_VDB`) By write-protecting physical pages and catching write + faults. This is implemented for many Unix-like systems and for Win32. It is + not possible in a few environments. + * (`GWW_VDB`) By using the Win32 `GetWriteWatch` function to read dirty + bits. + * (`PROC_VDB`) By retrieving dirty bit information from /proc. (Currently + only Sun's Solaris supports this. Though this is considerably cleaner, + performance may actually be better with `mprotect` and signals.) + * (`SOFT_VDB`) By retrieving Linux soft-dirty bit information from /proc. + * (`PCR_VDB`) By relying on an external dirty bit implementation, in this + case the one in Xerox PCR. + * Through explicit mutator cooperation. This enabled by + `GC_set_manual_vdb_allowed(1)` call, and requires the client code to call + `GC_ptr_store_and_dirty` or `GC_end_stubborn_change` (followed by a number + of `GC_reachable_here` calls), and is rarely used. + * (`DEFAULT_VDB`) By treating all pages as dirty. This is the default + if none of the other techniques is known to be usable. (Practical only for + testing.) + +## Black-listing + +The collector implements _black-listing_ of pages, as described in +["Space Efficient Conservative Collection", PLDI'93](http://dl.acm.org/citation.cfm?doid=155090.155109) +by Boehm, also available +[here](https://www.cs.rice.edu/~javaplt/311/Readings/pldi93.pdf). + +During the mark phase, the collector tracks _near misses_, i.e. attempts +to follow a _pointer_ to just outside the garbage-collected heap, or to +a currently unallocated page inside the heap. Pages that have been the targets +of such near misses are likely to be the targets of misidentified _pointers_ +in the future. To minimize the future damage caused by such misidentification, +they will be allocated only to small pointer-free objects. + +The collector understands two different kinds of black-listing. A page may be +black listed for interior pointer references (`GC_add_to_black_list_stack`), +if it was the target of a near miss from a location that requires interior +pointer recognition, e.g. the stack, or the heap if `GC_all_interior_pointers` +is set. In this case, we also avoid allocating large blocks that include this +page. + +If the near miss came from a source that did not require interior pointer +recognition, it is black-listed with `GC_add_to_black_list_normal`. A page +black-listed in this way may appear inside a large object, so long as it is +not the first page of a large object. + +The `GC_allochblk` routine respects black-listing when assigning a block to +a particular object kind and size. It occasionally drops (i.e. allocates and +forgets) blocks that are completely black-listed in order to avoid excessively +long large block free lists containing only unusable blocks. This would +otherwise become an issue if there is low demand for small pointer-free +objects. + +## Thread support + +We support several different threading models. Unfortunately Pthreads, the +only reasonably well standardized thread model, supports too narrow +an interface for conservative garbage collection. There appears to be no +completely portable way to allow the collector to coexist with various +Pthreads implementations. Hence we currently support only the more common +Pthreads implementations. + +In particular, it is very difficult for the collector to stop all other +threads in the system and examine the register contents. This is currently +accomplished with very different mechanisms for some Pthreads implementations. +For Linux/HPUX/OSF1, Solaris and Irix it sends signals to individual Pthreads +and has them wait in the signal handler. + +The Linux and Irix implementations use only documented Pthreads calls, but +rely on extensions to their semantics. The Linux implementation +`pthread_stop_world.c` relies on only very mild extensions to the pthreads +semantics, and already supports a large number of other Unix-like pthreads +implementations. Our goal is to make this the only pthread support in the +collector. + +All implementations must intercept thread creation and a few other +thread-specific calls to allow enumeration of threads and location of thread +stacks. This is current accomplished with `#define`'s in `gc.h` (really +`gc_pthread_redirects.h`), or optionally by using `ld`'s function call +wrapping mechanism under Linux. + +The collector support several facilities to enhance the processor-scalability +and thread performance of the collector. These are discussed in more detail +[here](scale.md). We briefly outline the data approach to thread-local +allocation in the next section. + +## Thread-local allocation + +If thread-local allocation is enabled (which is true in the default +configuration for most supported platforms), the collector keeps separate +arrays of free lists for each thread. + +The free list arrays associated with each thread are only used to satisfy +requests for objects that are both very small, and belong to one of a small +number of well-known kinds. These include _normal_, pointer-free, _gcj_ and +_disclaim_ objects. + +Thread-local free list entries contain either a pointer to the first element +of a free list, or they contain a counter of the number of allocation +granules, corresponding to objects of this size, allocated so far. Initially +they contain the value one, i.e. a small counter value. + +Thread-local allocation goes directly through the global allocator if the +object is of a size or kind not covered by the local free lists. + +If there is an appropriate local free list, the allocator checks whether +it contains a sufficiently small counter value. If so, the counter is simply +incremented by a value, and the global allocator is used. In this way, +the initial few allocations of a given size bypass the local allocator. +A thread that only allocates a handful of objects of a given size will not +build up its own free list for that size. This avoids wasting space for +unpopular objects sizes or kinds. + +Once the counter passes a threshold, `GC_malloc_many` is called to allocate +roughly `HBLKSIZE` space and put it on the corresponding local free list. +Further allocations of that size and kind then use this free list, and no +longer need to acquire the allocation lock. The allocation procedure +is otherwise similar to the global free lists. The local free lists are also +linked using the first word in the object. In most cases this means they +require considerably less time. + +Local free lists are treated by most of the rest of the collector as though +they were in-use reachable data. This requires some care, since pointer-free +objects are not normally traced, and hence a special tracing procedure +is required to mark all objects on pointer-free and gcj local free lists. + +On thread exit, any remaining thread-local free list entries are transferred +back to the global free list. + +Note that if the collector is configured for thread-local allocation (the +default for most platforms), `GC_malloc` and friends only use thread-local +allocation. + +For some more details see [here](scale.md), and the technical report entitled +["Fast Multiprocessor Memory Allocation and Garbage Collection"](http://www.hpl.hp.com/techreports/2000/HPL-2000-165.html). diff --git a/graphics/asymptote/gc/doc/gcinterface.md b/graphics/asymptote/gc/doc/gcinterface.md new file mode 100644 index 0000000000..8247ba2264 --- /dev/null +++ b/graphics/asymptote/gc/doc/gcinterface.md @@ -0,0 +1,216 @@ +# C/C++ Interface + +On many platforms, a single-threaded garbage collector library can be built +to act as a plug-in `malloc` replacement.

It describes only the most +commonly used functionality, approximately in decreasing order of frequency +of use. This somewhat duplicates the information in `gc.man` file. The full +interface is described in `gc.h` file. + +Clients should include `gc.h` (i.e., not `gc_config_macros.h`, +`gc_pthread_redirects.h`, `gc_version.h`). In the case of multi-threaded code, +`gc.h` should be included after the threads header file, and after defining +`GC_THREADS` macro. The header file `gc.h` must be included in files that use +either GC or threads primitives, since threads primitives will be redefined +to cooperate with the GC on many platforms. + +Thread users should also be aware that on many platforms objects reachable +only from thread-local variables may be prematurely reclaimed.

Requires (amortized) time proportional to _bytes_. The resulting +object will be automatically deallocated when unreferenced. The client +promises that the resulting object will never contain any pointers. The memory +is not cleared. This is the preferred way to allocate strings, floating point +arrays, bitmaps, etc. More precise information about pointer locations can be +communicated to the collector using the interface in `gc_typed.h`. + +`void * GC_MALLOC_UNCOLLECTABLE(size_t _bytes_)` - Identical +to `GC_MALLOC`, except that the resulting object is not automatically +deallocated. Unlike the system-provided `malloc`, the collector does scan the +object for pointers to garbage-collectible memory, even if the block itself +does not appear to be reachable. (Objects allocated in this way are +effectively treated as roots by the collector.) + +`void * GC_REALLOC(void * _old_object_, size_t _new_bytes_)` - Allocates +a new object of the indicated size and copy the old object's content into the +new object. The old object is reused in place if convenient. If the original +object was allocated with `GC_MALLOC_ATOMIC`, the new object is subject to the +same constraints. If it was allocated as an uncollectible object, then the new +object is uncollectible, and the old object (if different) is deallocated. + +`void GC_FREE(void * _object_)` - Explicitly deallocates an _object_. +Typically not useful for small collectible objects. + +`void * GC_MALLOC_IGNORE_OFF_PAGE(size_t _bytes_)` and +`void * GC_MALLOC_ATOMIC_IGNORE_OFF_PAGE(size_t _bytes_)` - Analogous +to `GC_MALLOC` and `GC_MALLOC_ATOMIC`, respectively, except that the client +guarantees that as long as the resulting object is of use, a pointer +is maintained to someplace inside the first heap block (hblk) of the object. +This pointer should be declared volatile to avoid interference from compiler +optimizations. (Other nonvolatile pointers to the object may exist as well.) +This is the preferred way to allocate objects that are likely to be +more than 100 KB in size. It greatly reduces the risk that such objects will +be accidentally retained when they are no longer needed. Thus space usage may +be significantly reduced. Another way is `GC_set_all_interior_pointers(0)` +called at program start (this, however, is generally not suitable for C++ code +because of multiple inheritance). + +`void GC_INIT()` - On some platforms, it is necessary to invoke this _from +the main executable_, _not from a dynamic library_, before the initial +invocation of a GC routine. It is recommended that this be done in portable +code, though we try to ensure that it expands to a no-op on as many platforms +as possible. + +`void GC_gcollect(void)` - Explicitly forces a garbage collection. + +`void GC_enable_incremental(void)` - Causes the garbage collector +to perform a small amount of work every few invocations of `GC_MALLOC` or the +like, instead of performing an entire collection at once. This is likely +to increase total running time. It will improve response on a platform that +has suitable support in the garbage collector (Linux and most Unix versions, +Win32 if the collector was suitably built). On many platforms this interacts +poorly with system calls that write to the garbage collected heap. + +`void GC_set_warn_proc(GC_warn_proc)` - Replaces the default procedure +used by the collector to print warnings. The collector may otherwise +write to `stderr`, most commonly because `GC_malloc` was used in a situation +in which `GC_malloc_ignore_off_page` would have been more appropriate. See +`gc.h` for details. + +`void GC_REGISTER_FINALIZER(...)` - Registers a function to be called when +an object becomes inaccessible. This is often useful as a backup method for +releasing system resources (e.g. closing files) when the object referencing +them becomes inaccessible. It is not an acceptable method to perform actions +that must be performed in a timely fashion. See `gc.h` for details of the +interface. See also [here](finalization.md) for a more detailed discussion +of the design. Note that an object may become inaccessible before client code +is done operating on objects referenced by its fields. Suitable +synchronization is usually required. See +[here](http://portal.acm.org/citation.cfm?doid=604131.604153) or +[here](http://www.hpl.hp.com/techreports/2002/HPL-2002-335.html) for details. + +If you are concerned with multiprocessor performance and scalability, you +should consider enabling and using thread local allocation. + +If your platform supports it, you should also build the collector with +parallel marking support (`-DPARALLEL_MARK`); configure has it on by default. + +If the collector is used in an environment in which pointer location +information for heap objects is easily available, this can be passed on to the +collector using the interfaces in either `gc_typed.h` or `gc_gcj.h`. + +The collector distribution also includes a **string package** that takes +advantage of the collector. For details see `cord.h` file. + +## C++ Interface + +The C++ interface is implemented as a thin layer on the C interface. +Unfortunately, this thin layer appears to be very sensitive to variations +in C++ implementations, particularly since it tries to replace the global +`::new` operator, something that appears to not be well-standardized. Your +platform may need minor adjustments in this layer (`gc_badalc.cc`, +`gc_cpp.cc`, `gc_cpp.h`, and possibly `gc_allocator.h`). Such changes do not +require understanding of collector internals, though they may require a good +understanding of your platform. (Patches enhancing portability are welcome. +But it is easy to break one platform by fixing another.) + +Usage of the collector from C++ is also complicated by the fact that there are +many _standard_ ways to allocate memory in C++. The default `::new` operator, +default `malloc`, and default STL allocators allocate memory that is not +garbage collected, and is not normally _traced_ by the collector. This means +that any pointers in memory allocated by these default allocators will not be +seen by the collector. Garbage-collectible memory referenced only by pointers +stored in such default-allocated objects is likely to be reclaimed prematurely +by the collector. + +It is the programmers responsibility to ensure that garbage-collectible memory +is referenced by pointers stored in one of + + * Program variables + * Garbage-collected objects + * Uncollected but _traceable_ objects + +Traceable objects are not necessarily reclaimed by the collector, but are +scanned for pointers to collectible objects. They are usually allocated +by `GC_MALLOC_UNCOLLECTABLE`, as described above, and through some interfaces +described below. + +On most platforms, the collector may not trace correctly from in-flight +exception objects. Thus objects thrown as exceptions should only point +to otherwise reachable memory. This is another bug whose proper repair +requires platform hooks. + +The easiest way to ensure that collectible objects are properly referenced +is to allocate only collectible objects. This requires that every allocation +go through one of the following interfaces, each one of which replaces +a standard C++ allocation mechanism. Note that this requires that all STL +containers be explicitly instantiated with `gc_allocator`. + +### STL allocators + +Recent versions of the collector include a hopefully standard-conforming +allocator implementation in `gc_allocator.h`. It defines `traceable_allocator` +and `gc_allocator` which may be used either directly to allocate memory or to +instantiate container templates. The former allocates uncollectible but traced +memory. The latter allocates garbage-collected memory. + +These should work with any fully standard-conforming C++ compiler. + +### Class inheritance based interface for new-based allocation + +Users may include `gc_cpp.h` and then cause members of classes to be allocated +in garbage collectible memory by having those classes inherit from class `gc`. +For details see `gc_cpp.h` file. + +Linking against `gccpp` in addition to the `gc` library overrides `::new` +(and friends) to allocate traceable but uncollectible memory, making +it safe to refer to collectible objects from the resulting memory. + +If the user includes `gc_cpp.h` but `::new` should not be overridden then +`gctba` (in addition to the `gc`) library should be linked with to provide +the definition of `GC_throw_bad_alloc` C++ function used by operator `new` of +class `gc`. Alternatively, the client may define `GC_NEW_ABORTS_ON_OOM` macro +before include of `gc_cpp.h` (this instructs `::new` to issue an abort instead +of throwing an exception), or may define `GC_INCLUDE_NEW` one before include +of `gc_cpp.h` (however, this might not compile or work as expected on some +platforms). + +## C interface + +It is also possible to use the C interface from `gc.h` directly. On platforms +which use `malloc` to implement `::new`, it should usually be possible to use +a version of the collector that has been compiled as a `malloc` replacement. +It is also possible to replace `::new` and other allocation functions +suitably, as is done by `gccpp`. + +Note that user-implemented small-block allocation often works poorly with +an underlying garbage-collected large block allocator, since the collector has +to view all objects accessible from the user's free list as reachable. This +is likely to cause problems if `GC_MALLOC` is used with something like the +original HP version of STL. This approach works well with the SGI versions +of the STL only if the `malloc_alloc` allocator is used. diff --git a/graphics/asymptote/gc/doc/leak.md b/graphics/asymptote/gc/doc/leak.md new file mode 100644 index 0000000000..6b5ed22666 --- /dev/null +++ b/graphics/asymptote/gc/doc/leak.md @@ -0,0 +1,160 @@ +# Using the Garbage Collector as Leak Detector + +The garbage collector may be used as a leak detector. In this case, the +primary function of the collector is to report objects that were allocated +(typically with `GC_MALLOC`), not deallocated (normally with `GC_FREE`), but +are no longer accessible. Since the object is no longer accessible, there +is normally no way to deallocate the object at a later time; thus it can +safely be assumed that the object has been "leaked". + +This is substantially different from counting leak detectors, which simply +verify that all allocated objects are eventually deallocated. +A garbage-collector based leak detector can provide somewhat more precise +information when an object was leaked. More importantly, it does not report +objects that are never deallocated because they are part of "permanent" data +structures. Thus it does not require all objects to be deallocated at process +exit time, a potentially useless activity that often triggers large amounts +of paging. + +The garbage collector provides leak detection support. This includes the +following features: + + 1. Leak detection mode can be initiated at run-time by `GC_set_find_leak(1)` + call at program startup instead of building the collector with `FIND_LEAK` + macro defined. + 2. Leaked objects should be reported and then correctly garbage collected. + +To use the collector as a leak detector, do the following steps: + + 1. Activate the leak detection mode as described above. + 2. Change the program so that all allocation and deallocation goes through + the garbage collector. + 3. Arrange to call `GC_gcollect` (or `CHECK_LEAKS()`) at appropriate points + to check for leaks. (This happens implicitly but probably not with + a sufficient frequency for long running programs.) + +The second step can usually be accomplished with the +`-DREDIRECT_MALLOC=GC_malloc` option when the collector is built, or by +defining `malloc`, `calloc`, `realloc`, `free` (as well as `strdup`, +`strndup`, `wcsdup`, `memalign`, `posix_memalign`) to call the corresponding +garbage collector functions. But this, by itself, will not yield very +informative diagnostics, since the collector does not keep track of the +information about how objects were allocated. The error reports will include +only object addresses. + +For more precise error reports, as much of the program as possible should use +the all uppercase variants of these functions, after defining `GC_DEBUG`, and +then including `gc.h`. In this environment `GC_MALLOC` is a macro which causes +at least the file name and line number at the allocation point to be saved +as part of the object. Leak reports will then also include this information. + +Many collector features (e.g. finalization and disappearing links) are less +useful in this context, and are not fully supported. Their use will usually +generate additional bogus leak reports, since the collector itself drops some +associated objects. + +The same is generally true of thread support. However, the correct leak +reports should be generated with linuxthreads, at least. + +On a few platforms (currently Solaris/SPARC, Irix, and, with +`-DSAVE_CALL_CHAIN`, Linux/x86), `GC_MALLOC` also causes some more information +about its call stack to be saved in the object. Such information is reproduced +in the error reports in very non-symbolic form, but it can be very useful with +the aid of a debugger. + +## An Example + +The `leak_detector.h` file is included in the "include" subdirectory of the +distribution. + +Assume the collector has been built with `-DFIND_LEAK` or +`GC_set_find_leak(1)` exists as the first statement in `main`. + +The program to be tested for leaks could look like `tests/leak_test.c` file +of the distribution. + +On a Linux/x86 system this produces on the stderr stream: + + + Found 1 leaked objects: + 0x806dff0 (tests/leak_test.c:19, sz=4, NORMAL) + + +(On most unmentioned operating systems, the output is similar to this. If the +collector had been built on Linux/x86 with `-DSAVE_CALL_CHAIN`, the output +would be closer to the Solaris example. For this to work, the program should +not be compiled with `-fomit_frame_pointer`.) + +On Irix it reports: + + + Found 1 leaked objects: + 0x10040fe0 (tests/leak_test.c:19, sz=4, NORMAL) + Caller at allocation: + ##PC##= 0x10004910 + + +and on Solaris the error report is: + + + Found 1 leaked objects: + 0xef621fc8 (tests/leak_test.c:19, sz=4, NORMAL) + Call chain at allocation: + args: 4 (0x4), 200656 (0x30FD0) + ##PC##= 0x14ADC + args: 1 (0x1), -268436012 (0xEFFFFDD4) + ##PC##= 0x14A64 + + +In the latter two cases some additional information is given about how malloc +was called when the leaked object was allocated. For Solaris, the first line +specifies the arguments to `GC_debug_malloc` (the actual allocation routine), +The second one specifies the program counter inside `main`, the third one +specifies the arguments to `main`, and, finally, the program counter inside +the caller to `main` (i.e. in the C startup code). In the Irix case, only the +address inside the caller to `main` is given. + +In many cases, a debugger is needed to interpret the additional information. +On systems supporting the `adb` debugger, the `tools/callprocs.sh` script can +be used to replace program counter values with symbolic names. The collector +tries to generate symbolic names for call stacks if it knows how to do so on +the platform. This is true on Linux/x86, but not on most other platforms. + +## Simplified leak detection under Linux + +It should be possible to run the collector in the leak detection mode on +a program a.out under Linux/x86 as follows: + + 1. If possible, ensure that a.out is a single-threaded executable. On some + platforms this does not work at all for the multi-threaded programs. + 2. If possible, ensure that the `addr2line` program is installed + in `/usr/bin`. (It comes with most Linux distributions.) + 3. If possible, compile your program, which we'll call `a.out`, with full + debug information. This will improve the quality of the leak reports. + With this approach, it is no longer necessary to call `GC_` routines + explicitly, though that can also improve the quality of the leak reports. + 4. Build the collector and install it in directory _foo_ as follows (it may + be safe to omit the `--disable-threads` option on Linux, but the combination + of thread support and `malloc` replacement is not yet rock solid): + + - `configure --prefix=_foo_ --enable-gc-debug --enable-redirect-malloc --disable-threads` + - `make` + - `make install` + + 5. Set environment variables as follows (the last two are optional, just to + confirm the collector is running, and to facilitate debugging from another + console window if something goes wrong, respectively): + + - `LD_PRELOAD=_foo_/lib/libgc.so` + - `GC_FIND_LEAK` + - `GC_PRINT_STATS` + - `GC_LOOP_ON_ABORT` + + 6. Simply run `a.out` as you normally would. Note that if you run anything + else (e.g. your editor) with those environment variables set, it will also + be leak tested. This may or may not be useful and/or embarrassing. It can + generate mountains of leak reports if the application was not designed + to avoid leaks, e.g. because it's always short-lived. + +This has not yet been thoroughly tested on large applications, but it's known +to do the right thing on at least some small ones. diff --git a/graphics/asymptote/gc/doc/overview.md b/graphics/asymptote/gc/doc/overview.md new file mode 100644 index 0000000000..465e2e0075 --- /dev/null +++ b/graphics/asymptote/gc/doc/overview.md @@ -0,0 +1,311 @@ +[Interface Overview](gcinterface.md) | [Tutorial Slides](http://www.hboehm.info/gc/04tutorial.pdf) | [FAQ](http://www.hboehm.info/gc/faq.html) | [Example](simple_example.md) | [Download](https://github.com/ivmai/bdwgc/wiki/Download) | [License](http://www.hboehm.info/gc/license.txt) +---|---|---|---|---|--- + +# A garbage collector for C and C++ + + * Platforms + * Some collector details + * Further reading + * Information provided on the BDWGC site + * More background information + * Contacts and new release announcements + +[ This is an updated version of the page formerly at +`www.hpl.hp.com/personal/Hans_Boehm/gc/`, before that at +`http://reality.sgi.com/boehm/gc.html` and before that at +`ftp://ftp.parc.xerox.com/pub/gc/gc.html`. ] + +The +[Boehm](http://www.hboehm.info)-[Demers](http://www.cs.cornell.edu/annual_report/00-01/bios.htm#demers)-[Weiser](http://www.ubiq.com/hypertext/weiser/weiser.html) +conservative Garbage Collector (**BDWGC**) can be used as a garbage collecting +replacement for C `malloc` or C++ `new`. It allows you to allocate memory +basically as you normally would, without explicitly deallocating memory that +is no longer useful. The collector automatically recycles memory when +it determines that it can no longer be otherwise accessed.

Exceptions are discussed +[here](http://www.hboehm.info/gc/issues.html). + +## Platforms + +The collector is not completely portable, but the distribution includes ports +to most standard PC and UNIX/Linux platforms. The collector should work +on Linux, Android, BSD variants, OS/2, Windows (Win32 and Win64), MacOS X, +iOS, HP/UX, Solaris, Tru64, Irix, Symbian and other operating systems. Some +platforms are more polished (better supported) than others. + +Irix pthreads, Linux threads, Windows threads, Solaris threads (pthreads +only), HP/UX 11 pthreads, Tru64 pthreads, and MacOS X threads are supported. + +## Some Collector Details + +The collector uses a [mark-sweep](http://www.hboehm.info/gc/complexity.html) +algorithm. It provides incremental and generational collection under operating +systems which provide the right kind of virtual memory support. (Currently +this includes SunOS[45], IRIX, OSF/1, Linux, and Windows, with varying +restrictions.) It allows [finalization](finalization.md) code to be invoked +when an object is collected. It can take advantage of type information +to locate pointers if such information is provided, but it is usually used +without such information. See the README and `gc.h` files in the distribution +for more details. + +For an overview of the implementation, see [here](gcdescr.md). + +The garbage collector distribution includes a C string (`cord.h`) package that +provides for fast concatenation and substring operations on long strings. +A simple curses- and Windows-based editor that represents the entire file as +a cord is included as a sample application. + +Performance of the non-incremental collector is typically competitive with +`malloc`/`free` implementations. Both space and time overhead are likely to be +only slightly higher for programs written for `malloc`/`free` (see Detlefs, +Dosser and Zorn's +[Memory Allocation Costs in Large C and C++ Programs](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.30.3073&rep=rep1&type=ps)). +For programs allocating primarily very small objects, the collector may be +faster; for programs allocating primarily large objects it will be slower. +If the collector is used in a multi-threaded environment and configured for +thread-local allocation, it may in some cases significantly outperform +`malloc`/`free` allocation in time. + +We also expect that in many cases any additional overhead will be more than +compensated for by e.g. decreased copying if programs are written and tuned +for garbage collection. + +## Further reading + +**The beginnings of a frequently asked questions list for this collector are +[here](http://www.hboehm.info/gc/faq.html).** + +**The following provide information on garbage collection in general:** + +Paul Wilson's +[garbage collection ftp archive](ftp://ftp.cs.utexas.edu/pub/garbage) +and [GC survey](ftp://ftp.cs.utexas.edu/pub/garbage/gcsurvey.ps). + +The Ravenbrook +[Memory Management Reference](http://www.memorymanagement.org/). + +David Chase's [GC FAQ](http://www.iecc.com/gclist/GC-faq.html). + +Richard Jones' +[Garbage Collection Page](https://www.cs.kent.ac.uk/people/staff/rej/gc.html) +and his [book](http://www.cs.kent.ac.uk/people/staff/rej/gcbook/gcbook.html). + +**The following papers describe the collector algorithms we use and the +underlying design decisions at a higher level:** + +(Some of the lower level details can be found [here](gcdescr.md).) + +The first one is not available electronically due to copyright considerations. +Most of the others are subject to ACM copyright. + +Boehm, H., Dynamic Memory Allocation and Garbage Collection, +_Computers in Physics 9_, 3, May/June 1995, pp. 297-303.

The collector inherently has to perform operations, such +as scanning the stack(s), that are not possible in portable C code. + +All of the following assumes that the collector is being ported to +a byte-addressable 32- or 64-bit machine. Currently all successful ports +to 64-bit machines involve LP64 and LLP64 targets (notably Win64). You +are hereby discouraged from attempting a port to non-byte-addressable, +or 8-bit, or 16-bit machines. + +The difficulty of porting the collector varies greatly depending on the needed +functionality. In the simplest case, only some small additions are needed for +the `include/private/gcconfig.h` file. This is described in the following +section. Later sections discuss some of the optional features, which typically +involve more porting effort. + +Note that the collector makes heavy use of `ifdef`s. Unlike some other +software projects, we have concluded repeatedly that this is preferable +to system dependent files, with code duplicated between the files. However, +to keep this manageable, we do strongly believe in indenting `ifdef`s +correctly (for historical reasons usually without the leading sharp sign). +(Separate source files are of course fine if they do not result in code +duplication.) + +## Adding Platforms to gcconfig.h + +If neither thread support, nor tracing of dynamic library data is required, +these are often the only changes you will need to make. + +The `gcconfig.h` file consists of three sections: + + 1. A section that defines GC-internal macros that identify the architecture + (e.g. `IA64` or `I386`) and operating system (e.g. `LINUX` or `MSWIN32`). + This is usually done by testing predefined macros. By defining our own + macros instead of using the predefined ones directly, we can impose a bit + more consistency, and somewhat isolate ourselves from compiler differences. + It is relatively straightforward to add a new entry here. But please try + to be consistent with the existing code. In particular, 64-bit variants + of 32-bit architectures general are _not_ treated as a new architecture. + Instead we explicitly test for 64-bit-ness in the few places in which + it matters. (The notable exception here is `I386` and `X86_64`. This + is partially historical, and partially justified by the fact that there are + arguably more substantial architecture and ABI differences here than for + RISC variants.) On GNU-based systems, `cpp -dM empty_source_file.c` seems + to generate a set of predefined macros. On some other systems, the "verbose" + compiler option may do so, or the manual page may list them. + + 2. A section that defines a small number of platform-specific macros, which + are then used directly by the collector. For simple ports, this is where + most of the effort is required. We describe the macros below. This section + contains a subsection for each architecture (enclosed in a suitable `ifdef`. + Each subsection usually contains some architecture-dependent defines, + followed by several sets of OS-dependent defines, again enclosed in + `ifdef`s. + + 3. A section that fills in defaults for some macros left undefined in the + preceding section, and defines some other macros that rarely need adjustment + for new platforms. You will typically not have to touch these. If you are + porting to an OS that was previously completely unsupported, it is likely + that you will need to add another clause to the definition of `GET_MEM`. + +The following macros must be defined correctly for each architecture and +operating system: + + * `MACH_TYPE` - Defined to a string that represents the machine + architecture. Usually just the macro name used to identify the architecture, + but enclosed in quotes. + * `OS_TYPE` - Defined to a string that represents the operating system name. + Usually just the macro name used to identify the operating system, but + enclosed in quotes. + * `CPP_WORDSZ` - The word size in bits as a constant suitable for + preprocessor tests, i.e. without casts or `sizeof` expressions. Currently + always defined as either 64 or 32. For platforms supporting both 32- and + 64-bit ABIs, this should be conditionally defined depending on the current + ABI. There is a default of 32. + * `ALIGNMENT` - Defined to be the largest _N_ such that all pointer + are guaranteed to be aligned on _N_-byte boundaries. Defining it to be _1_ + will always work, but perform poorly. For all modern 32-bit platforms, this + is 4. For all modern 64-bit platforms, this is 8. Whether or not x86 + qualifies as a modern architecture here is compiler- and OS-dependent. + * `DATASTART` - The beginning of the main data segment. The collector will + trace all memory between `DATASTART` and `DATAEND` for root pointers. + On some platforms, this can be defined to a constant address, though + experience has shown that to be risky. Ideally the linker will define + a symbol (e.g. `_data`) whose address is the beginning of the data segment. + Sometimes the value can be computed using the `GC_SysVGetDataStart` + function. Not used if either the next macro is defined, or if dynamic + loading is supported, and the dynamic loading support defines a function + `GC_register_main_static_data` which returns false. + * `SEARCH_FOR_DATA_START` - If this is defined `DATASTART` will be defined + to a dynamically computed value which is obtained by starting with the + address of `_end` and walking backwards until non-addressable memory + is found. This often works on Posix-like platforms. It makes it harder + to debug client programs, since startup involves generating and catching + a segmentation fault, which tends to confuse users. + * `DATAEND` - Set to the end of the main data segment. Defaults to `_end`, + where that is declared as an array. This works in some cases, since the + linker introduces a suitable symbol. + * `DATASTART2`, `DATAEND2` - Some platforms have two discontiguous main data + segments, e.g. for initialized and uninitialized data. If so, these two + macros should be defined to the limits of the second main data segment. + * `STACK_GROWS_UP` - Should be defined if the stack (or thread stacks) grow + towards higher addresses. (This appears to be true only on PA-RISC. If your + architecture has more than one stack per thread, and is not supported yet, + you will need to do more work. Grep for "IA64" in the source for an + example.) + * `STACKBOTTOM` - Defined to be the cold end of the stack, which is usually + (i.e. when the stacks grow down) the highest address in the stack. It must + bound the region of the stack that contains pointers into the GC heap. With + thread support, this must be the cold end of the main stack, which typically + cannot be found in the same way as the other thread stacks. If this is not + defined and none of the following three macros is defined, client code must + explicitly set `GC_stackbottom` to an appropriate value before calling + `GC_INIT` or any other `GC_` routine. + * `LINUX_STACKBOTTOM` - May be defined instead of `STACKBOTTOM`. If defined, + then the cold end of the stack will be determined, we usually read it from + `/proc`. + * `HEURISTIC1` - May be defined instead of `STACKBOTTOM`. `STACK_GRAN` + should generally also be redefined. The cold end of the stack is determined + by taking an address inside `GC_init`s frame, and rounding it up to the next + multiple of `STACK_GRAN`. This works well if the stack bottom is always + aligned to a large power of two. (`STACK_GRAN` is predefined to 0x1000000, + which is rarely optimal.) + * `HEURISTIC2` - May be defined instead of `STACKBOTTOM`. The cold end + of the stack is determined by taking an address inside `GC_init`s frame, + incrementing it repeatedly in small steps (decrement if `STACK_GROWS_UP`), + and reading the value at each location. We remember the value when the first + Segmentation violation or Bus error is signaled, round that to the nearest + plausible page boundary, and use that as the stack bottom. + * `DYNAMIC_LOADING` - Should be defined if `dyn_load.c` has been updated for + this platform and tracing of dynamic library roots is supported. + * `GWW_VDB`, `MPROTECT_VDB`, `PROC_VDB`, `SOFT_VDB` - May be defined if the + corresponding _virtual dirty bit_ implementation in `os_dep.c` is usable on + this platform. This allows incremental/generational garbage collection. + (`GWW_VDB` uses the Win32 `GetWriteWatch` function to read dirty bits, + `MPROTECT_VDB` identifies modified pages by write protecting the heap and + catching faults. `PROC_VDB` and `SOFT_VDB` use the /proc pseudo-files to + read dirty bits.) + * `PREFETCH`, `GC_PREFETCH_FOR_WRITE` - The collector uses `PREFETCH(x)` + to preload the cache with the data at _x_ address. This defaults to a no-op. + * `CLEAR_DOUBLE` - If `CLEAR_DOUBLE` is defined, then `CLEAR_DOUBLE(x)` + is used as a fast way to clear the two words at `GC_malloc`-aligned address + _x_. By default, word stores of 0 are used instead. + * `HEAP_START` - May be defined as the initial address hint for mmap-based + allocation. + +## Additional requirements for a basic port + +In some cases, you may have to add additional platform-specific code to other +files. A likely candidate is the implementation +of `GC_with_callee_saves_pushed` in `mach_dep.c`. This ensure that register +contents that the collector must trace from are copied to the stack. Typically +this can be done portably, but on some platforms it may require assembly code, +or just tweaking of conditional compilation tests. + +If your platform supports `getcontext` then defining the macro +`UNIX_LIKE` for your OS in `gcconfig.h` (if it is not defined there yet) +is likely to solve the problem. Otherwise, if you are using gcc, +`_builtin_unwind_init` will be used, and should work fine. If that is not +applicable either, the implementation will try to use `setjmp`. This will work +if your `setjmp` implementation saves all possibly pointer-valued registers +into the buffer, as opposed to trying to unwind the stack at `longjmp` time. +The `setjmp_test` test tries to determine this, but often does not get it +right. Registers tracing handled with an assembly code is generally to be +avoided. + +Most commonly `os_dep.c` will not require attention, but see below. + +## Thread support + +Supporting threads requires that the collector be able to find and suspend all +threads potentially accessing the garbage-collected heap, and locate any state +associated with each thread that must be traced. + +The functionality needed for thread support is generally implemented in one or +more files specific to the particular thread interface. For example, somewhat +portable pthread support is implemented in `pthread_support.c` and +`pthread_stop_world.c`. The essential functionality consists of: + + * `GC_stop_world` - Stops all threads which may access the garbage collected + heap, other than the caller; + * `GC_start_world` - Restart other threads; + * `GC_push_all_stacks` - Push the contents of all thread stacks (or, + at least, of pointer-containing regions in the thread stacks) onto the mark + stack. + +These very often require that the garbage collector maintain its own data +structures to track active threads. + +In addition, `LOCK` and `UNLOCK` must be implemented in `gc_locks.h`. + +The easiest case is probably a new pthreads platform on which threads can be +stopped with signals. In this case, the changes involve: + + 1. Introducing a suitable `GC_xxx_THREADS` macro, which should + be automatically defined by `gc_config_macros.h` in the right cases. + It should also result in a definition of `GC_PTHREADS`, as for the existing + cases. + 2. Ensuring that the `atomic_ops` package at least minimally + supports the platform. If incremental GC is needed, or if pthread locks + do not perform adequately as the allocation lock, you will probably need + to ensure that a sufficient `atomic_ops` port exists for the platform + to provided an atomic test and set operation. The latest GC code can use + GCC atomic intrinsics instead of `atomic_ops` package (see + `include/private/gc_atomic_ops.h`). + 3. Making any needed adjustments to `pthread_stop_world.c` and + `pthread_support.c`. Ideally none should be needed. In fact, not all of this + is as well standardized as one would like, and outright bugs requiring + workarounds are common. Non-preemptive threads packages will probably + require further work. Similarly thread-local allocation and parallel marking + requires further work in `pthread_support.c`, and may require better + `atomic_ops` support for the designed platform. + +## Dynamic library support + +So long as `DATASTART` and `DATAEND` are defined correctly, the collector will +trace memory reachable from file scope or `static` variables defined as part +of the main executable. This is sufficient if either the program is statically +linked, or if pointers to the garbage-collected heap are never stored +in non-stack variables defined in dynamic libraries. + +If dynamic library data sections must also be traced, then: + + * `DYNAMIC_LOADING` must be defined in the appropriate section of + `gcconfig.h`. + * An appropriate versions of the functions `GC_register_dynamic_libraries` + should be defined in `dyn_load.c`. This function should invoke + `GC_cond_add_roots(region_start, region_end, TRUE)` on each dynamic + library data section. + +Implementations that scan for writable data segments are error prone, +particularly in the presence of threads. They frequently result in race +conditions when threads exit and stacks disappear. They may also accidentally +trace large regions of graphics memory, or mapped files. On at least one +occasion they have been known to try to trace device memory that could not +safely be read in the manner the GC wanted to read it. + +It is usually safer to walk the dynamic linker data structure, especially +if the linker exports an interface to do so. But beware of poorly documented +locking behavior in this case. + +## Incremental GC support + +For incremental and generational collection to work, `os_dep.c` must contain +a suitable _virtual dirty bit_ implementation, which allows the collector +to track which heap pages (assumed to be a multiple of the collector's block +size) have been written during a certain time interval. The collector provides +several implementations, which might be adapted. The default (`DEFAULT_VDB`) +is a placeholder which treats all pages as having been written. This ensures +correctness, but renders incremental and generational collection essentially +useless. + +## Stack traces for debug support + +If stack traces in objects are needed for debug support, `GC_save_callers` and +`GC_print_callers` must be implemented. + +## Disclaimer + +This is an initial pass at porting guidelines. Some things have no doubt been +overlooked. diff --git a/graphics/asymptote/gc/doc/scale.md b/graphics/asymptote/gc/doc/scale.md new file mode 100644 index 0000000000..77a83fd0db --- /dev/null +++ b/graphics/asymptote/gc/doc/scale.md @@ -0,0 +1,173 @@ +# Garbage collector scalability + +If Makefile.direct is used, in its default configuration the +Boehm-Demers-Weiser garbage collector is not thread-safe. Generally, it can be +made thread-safe by building the collector with `-DGC_THREADS` compilation +flag. This has primarily the following effects: + + 1. It causes the garbage collector to stop all other threads when it needs + to see a consistent memory state. It intercepts thread creation and + termination events to maintain a list of client threads to be stopped when + needed. + 2. It causes the collector to acquire a lock around essentially all + allocation and garbage collection activity. Since a single lock is used for + all allocation-related activity, only one thread can be allocating + or collecting at one point. This inherently limits performance + of multi-threaded applications on multiprocessors. + +On most platforms, the allocator/collector lock is implemented as a spin lock +with exponential back-off. Longer wait times are implemented by yielding +and/or sleeping. If a collection is in progress, the pure spinning stage +is skipped. This has the uncontested advantage that most uniprocessor lock +acquisitions are very cheap. It has the disadvantage that the application may +sleep for small periods of time even when there is work to be done. And +threads may be unnecessarily woken up for short periods. Nonetheless, this +scheme empirically outperforms native queue-based mutual exclusion +implementations in most cases, sometimes drastically so. + +## Options for enhanced scalability + +The collector uses two facilities to enhance collector scalability on +multiprocessors. They are intended to be used together. (The following refers +to Makefile.direct again.) + + * Building the collector with `-DPARALLEL_MARK` allows the collector to run + the mark phase in parallel in multiple threads, and thus on multiple + processors (or processor cores). The mark phase typically consumes the large + majority of the collection time. Thus, this largely parallelizes the garbage + collector itself, though not the allocation process. Currently the marking + is performed by the thread that triggered the collection, together with + _N_ - 1 dedicated threads, where _N_ is the number of processors (cores) + detected by the collector. The dedicated marker threads are created when the + client calls `GC_start_mark_threads()` or when the client starts the first + non-main thread after the GC initialization (or after fork operation in + a child process). Another effect of this flag is to switch to a more + concurrent implementation of `GC_malloc_many`, so that free lists can be + built and memory can be cleared by more than one thread concurrently. + * Building the collector with `-DTHREAD_LOCAL_ALLOC` adds support for + thread-local allocation. This causes `GC_malloc` (actually `GC_malloc_kind`) + and `GC_gcj_malloc` to be redefined to perform thread-local allocation. + +Memory returned from thread-local allocators is completely interchangeable +with that returned by the standard allocators. It may be used by other +threads. The only difference is that, if the thread allocates enough memory +of a certain kind, it will build a thread-local free list for objects of that +kind, and allocate from that. This greatly reduces locking. The thread-local +free lists are refilled using `GC_malloc_many`. + +An important side effect of this flag is to replace the default +spin-then-sleep lock to be replaced by a spin-then-queue based implementation. +This _reduces performance_ for the standard allocation functions, though +it usually improves performance when thread-local allocation is used heavily, +and, thus, the number of short-duration lock acquisitions is greatly reduced. + +## The Parallel Marking Algorithm + +We use an algorithm similar to +[that developed by Endo, Taura, and Yonezawa](http://www.yl.is.s.u-tokyo.ac.jp/gc/) +at the University of Tokyo. However, the data structures and implementation +are different, and represent a smaller change to the original collector +source, probably at the expense of extreme scalability. Some of the +refinements they suggest, e.g. splitting large objects, were also incorporated +into our approach. + +The global mark stack is transformed into a global work queue. Unlike the +usual case, it never shrinks during a mark phase. The mark threads remove +objects from the queue by copying them to a local mark stack and changing the +global descriptor to zero, indicating that there is no more work to be done +for this entry. This removal is done with no synchronization. Thus it is +possible for more than one worker to remove the same entry, resulting in some +work duplication. + +The global work queue grows only if a marker thread decides to return some +of its local mark stack to the global one. This is done if the global queue +appears to be running low, or if the local stack is in danger of overflowing. +It does require synchronization, but should be relatively rare. + +The sequential marking code is reused to process local mark stacks. Hence the +amount of additional code required for parallel marking is minimal. + +It should be possible to use incremental/generational collection in the +presence of the parallel collector by calling `GC_enable_incremental`, but +the current implementation does not allow interruption of the parallel marker, +so the latter is mostly avoided if the client sets the collection time limit. + +Gcj-style mark descriptors do not currently mix with the combination of local +allocation and incremental collection. They should work correctly with one or +the other, but not both. + +The number of marker threads is set on startup to the number of available +processor cores (or to the value of either `GC_MARKERS` or `GC_NPROCS` +environment variable, if provided). If only a single processor is detected, +parallel marking is disabled. + +Note that setting `GC_NPROCS` to 1 also causes some lock acquisitions inside +the collector to immediately yield the processor instead of busy waiting +first. In the case of a multiprocessor and a client with multiple +simultaneously runnable threads, this may have disastrous performance +consequences (e.g. a factor of 10 slowdown). + +## Performance + +We conducted some simple experiments with a version of +[our GC benchmark](http://www.hboehm.info/gc/gc_bench/) that was slightly +modified to run multiple concurrent client threads in the same address space. +Each client thread does the same work as the original benchmark, but they +share a heap. This benchmark involves very little work outside of memory +allocation. This was run with an ancient GC (released in 2000) on a dual +processor Pentium III/500 machine under Linux 2.2.12. + +Running with a thread-unsafe collector, the benchmark ran in 9 seconds. With +the simple thread-safe collector, built with `-DGC_THREADS`, the execution +time increased to 10.3 seconds, or 23.5 elapsed seconds with two clients. (The +times for the `malloc`/`free` version with glibc `malloc` are 10.51 (standard +library, pthreads not linked), 20.90 (one thread, pthreads linked), and 24.55 +seconds, respectively. The benchmark favors a garbage collector, since most +objects are small.) + +The following table gives execution times for the collector built with +parallel marking and thread-local allocation support +(`-DGC_THREADS -DPARALLEL_MARK -DTHREAD_LOCAL_ALLOC`). We tested the client +using either one or two marker threads, and running one or two client threads. +Note that the client uses thread local allocation exclusively. With +`-DTHREAD_LOCAL_ALLOC` the collector switches to a locking strategy that +is better tuned to less frequent lock acquisition. The standard allocation +primitives thus perform slightly worse than without `-DTHREAD_LOCAL_ALLOC`, +and should be avoided in time-critical code. + +(The results using `pthread_mutex_lock` directly for allocation locking would +have been worse still, at least for older versions of linuxthreads. With +`-DTHREAD_LOCAL_ALLOC`, we first repeatedly try to acquire the lock with +`pthread_mutex_try_lock`, busy-waiting between attempts. After a fixed number +of attempts, we use `pthread_mutex_lock`.) + +These measurements do not use incremental collection, nor was prefetching +enabled in the marker. We used the C version of the benchmark. All +measurements are in elapsed seconds on an unloaded machine. + +Number of client threads| 1 marker thread (secs.)| 2 marker threads (secs.) +---|------|----- + 1| 10.45| 7.85 + 2| 19.95| 12.3 + +The execution time for the single threaded case is slightly worse than with +simple locking. However, even the single-threaded benchmark runs faster than +even the thread-unsafe version if a second processor is available. The +execution time for two clients with thread local allocation time is only 1.4 +times the sequential execution time for a single thread in a thread-unsafe +environment, even though it involves twice the client work. That represents +close to a factor of 2 improvement over the 2 client case with the old +collector. The old collector clearly still suffered from some contention +overhead, in spite of the fact that the locking scheme had been fairly well +tuned. + +Full linear speedup (i.e. the same execution time for 1 client on one +processor as 2 clients on 2 processors) is probably not achievable on this +kind of hardware even with such a small number of processors, since the memory +system is a major constraint for the garbage collector, the processors usually +share a single memory bus, and thus the aggregate memory bandwidth does not +increase in proportion to the number of processors (cores). + +These results are likely to be very sensitive to both hardware and OS issues. +Preliminary experiments with an older Pentium Pro machine running an older +kernel were far less encouraging. diff --git a/graphics/asymptote/gc/doc/simple_example.md b/graphics/asymptote/gc/doc/simple_example.md new file mode 100644 index 0000000000..d24c9a085c --- /dev/null +++ b/graphics/asymptote/gc/doc/simple_example.md @@ -0,0 +1,182 @@ +# Using the Garbage Collector: A simple example + +The following consists of step-by-step instructions for building and using the +collector.

It runs +a basic correctness test which usually takes well under a minute. + +### Other platforms + +On non-Unix, non-Linux platforms, the collector is usually built by copying +the appropriate makefile (see the platform-specific README in doc/README.xxx +in the distribution) to the file "Makefile", and then typing `make` (or +`nmake` or ...). This builds the library in the source tree. You may want +to move it and the files in the include directory to a more convenient place. + +If you use a makefile that does not require running a configure script, you +should first look at the makefile, and adjust any options that are documented +there. + +If your platform provides a `make` utility, that is generally preferred +to platform- and compiler- dependent "project" files. (At least that is the +strong preference of the would-be maintainer of those project files.) + +### Threads + +If you do not need thread support, configure the collector with: + + + --disable-threads + + +Alternatively, if your target is a real old-fashioned uniprocessor (no +"hyperthreading", etc.), you may just want to turn off parallel marking with +`--disable-parallel-mark`. + +### C++ + +You will need to include the C++ support, which unfortunately tends to be +among the least portable parts of the collector, since it seems to rely +on some corner cases of the language. On Linux, it suffices to add +`--enable-cplusplus` to the configure options. + +## Writing the program + +You will need to include "gc.h" at the beginning of every file that allocates +memory through the garbage collector. Call `GC_MALLOC` wherever you would have +call `malloc`. This initializes memory to zero like `calloc`; there is no need +to explicitly clear the result. + +If you know that an object will not contain pointers to the garbage-collected +heap, and you don't need it to be initialized, call `GC_MALLOC_ATOMIC` +instead. + +A function `GC_FREE` is provided but need not be called.

This can never hurt, and is thus generally good practice. + +### Threads + +For a multi-threaded program, some more rules apply: + + * Files that either allocate through the GC _or make thread-related calls_ + should first define the macro `GC_THREADS`, and then include `gc.h`. On some + platforms this will redefine some threads primitives, e.g. to let the + collector keep track of thread creation. + +### C++ + +In the case of C++, you need to be especially careful not to store pointers +to the garbage-collected heap in areas that are not traced by the collector. +The collector includes some _alternate interfaces_ to make that easier. + +### Debugging + +Additional debug checks can be performed by defining `GC_DEBUG` before +including `gc.h`. Additional options are available if the collector is also +built with `--enable-gc-debug` and all allocations are performed with +`GC_DEBUG` defined. + +### What if I can't rewrite/recompile my program? + +You may be able to build the collector with `--enable-redirect-malloc` and set +the `LD_PRELOAD` environment variable to point to the resulting library, thus +replacing the standard `malloc` with its garbage-collected counterpart.

Each entry points to a `bottom_index` data +structure. This structure in turn consists mostly of an array `index` indexed +by the middle bits of the candidate pointer. The `index` array contains the +actual `hdr` pointers. + +Thus a pointer lookup consists primarily of a handful of memory references, +and can be quite fast: + + 1. The appropriate `bottom_index` pointer is looked up in `GC_top_index`, + based on the high bits of the candidate pointer. + 2. The appropriate `hdr` pointer is looked up in the `bottom_index` + structure, based on the middle bits. + 3. The block layout map pointer is retrieved from the `hdr` structure. (This + memory reference is necessary since we try to share block layout maps.) + 4. The displacement to the beginning of the object is retrieved from the + above map. + +In order to conserve space, not all `GC_top_index` entries in fact point +to distinct `bottom_index` structures. If no address with the corresponding +high bits is part of the heap, then the entry points to `GC_all_nils`, +a single `bottom_index` structure consisting only of `NULL` `hdr` pointers. + +`Bottom_index` structures contain slightly more information than just `hdr` +pointers. The `asc_link` field is used to link all `bottom_index` structures +in ascending order for fast traversal. This list is pointed to be +`GC_all_bottom_indices`. It is maintained with the aid of `key` field that +contains the high bits corresponding to the `bottom_index`. + +## 64-bit addresses + +In the case of 64-bit addresses, this picture is complicated slightly by the +fact that one of the index structures would have to be huge to cover the +entire address space with a two level tree.

Ellis and Jesse Hull + +This interface provides access to the Boehm collector. It provides +basic facilities similar to those described in "Safe, Efficient +Garbage Collection for C++", by John R. Ellis and David L. Detlefs +(ftp://ftp.parc.xerox.com/pub/ellis/gc). + +All heap-allocated objects are either "collectible" or +"uncollectible". Programs must explicitly delete uncollectible +objects, whereas the garbage collector will automatically delete +collectible objects when it discovers them to be inaccessible. +Collectible objects may freely point at uncollectible objects and vice +versa. + +Objects allocated with the built-in "::operator new" are uncollectible. + +Objects derived from class "gc" are collectible. For example: + + class A: public gc {...}; + A* a = new A; // a is collectible. + +Collectible instances of non-class types can be allocated using the GC +(or UseGC) placement: + + typedef int A[ 10 ]; + A* a = new (GC) A; + +Uncollectible instances of classes derived from "gc" can be allocated +using the NoGC placement: + + class A: public gc {...}; + A* a = new (NoGC) A; // a is uncollectible. + +The new(PointerFreeGC) syntax allows the allocation of collectible +objects that are not scanned by the collector. This useful if you +are allocating compressed data, bitmaps, or network packets. (In +the latter case, it may remove danger of unfriendly network packets +intentionally containing values that cause spurious memory retention.) + +Both uncollectible and collectible objects can be explicitly deleted +with "delete", which invokes an object's destructors and frees its +storage immediately. + +A collectible object may have a clean-up function, which will be +invoked when the collector discovers the object to be inaccessible. +An object derived from "gc_cleanup" or containing a member derived +from "gc_cleanup" has a default clean-up function that invokes the +object's destructors. Explicit clean-up functions may be specified as +an additional placement argument: + + A* a = ::new (GC, MyCleanup) A; + +An object is considered "accessible" by the collector if it can be +reached by a path of pointers from static variables, automatic +variables of active functions, or from some object with clean-up +enabled; pointers from an object to itself are ignored. + +Thus, if objects A and B both have clean-up functions, and A points at +B, B is considered accessible. After A's clean-up is invoked and its +storage released, B will then become inaccessible and will have its +clean-up invoked. If A points at B and B points to A, forming a +cycle, then that's considered a storage leak, and neither will be +collectible. See the interface gc.h for low-level facilities for +handling such cycles of objects with clean-up. + +The collector cannot guarantee that it will find all inaccessible +objects. In practice, it finds almost all of them. + + +Cautions: + +1. Be sure the collector has been augmented with "make c++" or +"--enable-cplusplus". + +2. If your compiler supports the new "operator new[]" syntax, then +add -DGC_OPERATOR_NEW_ARRAY to the Makefile. + +If your compiler doesn't support "operator new[]", beware that an +array of type T, where T is derived from "gc", may or may not be +allocated as a collectible object (it depends on the compiler). Use +the explicit GC placement to make the array collectible. For example: + + class A: public gc {...}; + A* a1 = new A[ 10 ]; // collectible or uncollectible? + A* a2 = new (GC) A[ 10 ]; // collectible. + +3. The destructors of collectible arrays of objects derived from +"gc_cleanup" will not be invoked properly. For example: + + class A: public gc_cleanup {...}; + A* a = new (GC) A[ 10 ]; // destructors not invoked correctly + +Typically, only the destructor for the first element of the array will +be invoked when the array is garbage-collected. To get all the +destructors of any array executed, you must supply an explicit +clean-up function: + + A* a = new (GC, MyCleanUp) A[ 10 ]; + +(Implementing clean-up of arrays correctly, portably, and in a way +that preserves the correct exception semantics requires a language +extension, e.g. the "gc" keyword.) + +4. Compiler bugs (now hopefully history): + +* Solaris 2's CC (SC3.0) doesn't implement t->~T() correctly, so the +destructors of classes derived from gc_cleanup won't be invoked. +You'll have to explicitly register a clean-up function with +new-placement syntax. + +* Evidently cfront 3.0 does not allow destructors to be explicitly +invoked using the ANSI-conforming syntax t->~T().

We assume byte addressability, where a byte has 8 bits. + * We also assume CPP_WORDSZ is either 32 or 64. + * (We care about the length of pointers, not hardware + * bus widths. Thus a 64 bit processor with a C compiler that uses + * 32 bit pointers should use CPP_WORDSZ of 32, not 64. Default is 32.) + * + * MACH_TYPE is a string representation of the machine type. + * OS_TYPE is analogous for the OS. + * + * ALIGNMENT is the largest N, such that + * all pointer are guaranteed to be aligned on N byte boundaries. + * defining it to be 1 will always work, but perform poorly. + * + * DATASTART is the beginning of the data segment. + * On some platforms SEARCH_FOR_DATA_START is defined. + * The latter will cause GC_data_start to + * be set to an address determined by accessing data backwards from _end + * until an unmapped page is found. DATASTART will be defined to be + * GC_data_start. + * On UNIX-like systems, the collector will scan the area between DATASTART + * and DATAEND for root pointers. + * + * DATAEND, if not "end", where "end" is defined as "extern int end[]". + * RTH suggests gaining access to linker script synth'd values with + * this idiom instead of "&end", where "end" is defined as "extern int end". + * Otherwise, "GCC will assume these are in .sdata/.sbss" and it will, e.g., + * cause failures on alpha*-*-* with -msmall-data or -fpic or mips-*-* + * without any special options. + * + * STACKBOTTOM is the cold end of the stack, which is usually the + * highest address in the stack. + * Under PCR or OS/2, we have other ways of finding thread stacks. + * For each machine, the following should: + * 1) define STACK_GROWS_UP if the stack grows toward higher addresses, and + * 2) define exactly one of + * STACKBOTTOM (should be defined to be an expression) + * LINUX_STACKBOTTOM + * HEURISTIC1 + * HEURISTIC2 + * If STACKBOTTOM is defined, then its value will be used directly (as the + * stack bottom). If LINUX_STACKBOTTOM is defined, then it will be determined + * with a method appropriate for most Linux systems. Currently we look + * first for __libc_stack_end (currently only if USE_LIBC_PRIVATES is + * defined), and if that fails read it from /proc. (If USE_LIBC_PRIVATES + * is not defined and NO_PROC_STAT is defined, we revert to HEURISTIC2.) + * If either of the last two macros are defined, then STACKBOTTOM is computed + * during collector startup using one of the following two heuristics: + * HEURISTIC1: Take an address inside GC_init's frame, and round it up to + * the next multiple of STACK_GRAN. + * HEURISTIC2: Take an address inside GC_init's frame, increment it repeatedly + * in small steps (decrement if STACK_GROWS_UP), and read the value + * at each location. Remember the value when the first + * Segmentation violation or Bus error is signaled. Round that + * to the nearest plausible page boundary, and use that instead + * of STACKBOTTOM. + * + * Gustavo Rodriguez-Rivera points out that on most (all?) Unix machines, + * the value of environ is a pointer that can serve as STACKBOTTOM. + * I expect that HEURISTIC2 can be replaced by this approach, which + * interferes far less with debugging. However it has the disadvantage + * that it's confused by a putenv call before the collector is initialized. + * This could be dealt with by intercepting putenv ... + * + * If no expression for STACKBOTTOM can be found, and neither of the above + * heuristics are usable, the collector can still be used with all of the above + * undefined, provided one of the following is done: + * 1) GC_mark_roots can be changed to somehow mark from the correct stack(s) + * without reference to STACKBOTTOM. This is appropriate for use in + * conjunction with thread packages, since there will be multiple stacks. + * (Allocating thread stacks in the heap, and treating them as ordinary + * heap data objects is also possible as a last resort. However, this is + * likely to introduce significant amounts of excess storage retention + * unless the dead parts of the thread stacks are periodically cleared.) + * 2) Client code may set GC_stackbottom before calling any GC_ routines. + * If the author of the client code controls the main program, this is + * easily accomplished by introducing a new main program, setting + * GC_stackbottom to the address of a local variable, and then calling + * the original main program. The new main program would read something + * like (provided real_main() is not inlined by the compiler): + * + * #include "gc.h" + * + * main(argc, argv, envp) + * int argc; + * char **argv, **envp; + * { + * volatile int dummy; + * + * GC_stackbottom = (ptr_t)(&dummy); + * return(real_main(argc, argv, envp)); + * } + * + * + * Each architecture may also define the style of virtual dirty bit + * implementation to be used: + * GWW_VDB: Use Win32 GetWriteWatch primitive. + * MPROTECT_VDB: Write protect the heap and catch faults. + * PROC_VDB: Use the SVR4 /proc primitives to read dirty bits. + * SOFT_VDB: Use the Linux /proc primitives to track dirty bits. + * + * The first and second one may be combined, in which case a runtime + * selection will be made, based on GetWriteWatch availability. + * + * An architecture may define DYNAMIC_LOADING if dyn_load.c + * defined GC_register_dynamic_libraries() for the architecture. + * + * An architecture may define PREFETCH(x) to preload the cache with *x. + * This defaults to GCC built-in operation (or a no-op for other compilers). + * + * GC_PREFETCH_FOR_WRITE(x) is used if *x is about to be written. + * + * An architecture may also define CLEAR_DOUBLE(x) to be a fast way to + * clear the two words at GC_malloc-aligned address x.

A GC_dirty() call on a large + * object directly dirties only a single page, but for the + * manual VDB we are careful to treat an object with a dirty + * page as completely dirty. + * In order to avoid races, an object must be marked dirty + * after it is written, and a reference to the object + * must be kept on a stack or in a register in the interim. + * With threads enabled, an object directly reachable from the + * stack at the time of a collection is treated as dirty. + * In single-threaded mode, it suffices to ensure that no + * collection can take place between the pointer assignment + * and the GC_dirty() call. + * PCR_VDB: Use PPCRs virtual dirty bit facility. + * PROC_VDB: Use the /proc facility for reading dirty bits. Only + * works under some SVR4 variants. Even then, it may be + * too slow to be entirely satisfactory. Requires reading + * dirty bits for entire address space. Implementations tend + * to assume that the client is a (slow) debugger. + * SOFT_VDB: Use the /proc facility for reading soft-dirty PTEs. + * Works on Linux 3.18+ if the kernel is properly configured. + * The proposed implementation iterates over GC_heap_sects and + * GC_static_roots examining the soft-dirty bit of the words + * in /proc/self/pagemap corresponding to the pages of the + * sections; finally all soft-dirty bits of the process are + * cleared (by writing some special value to + * /proc/self/clear_refs file). In case the soft-dirty bit is + * not supported by the kernel, MPROTECT_VDB may be defined as + * a fallback strategy. + * MPROTECT_VDB:Protect pages and then catch the faults to keep track of + * dirtied pages. The implementation (and implementability) + * is highly system dependent. This usually fails when system + * calls write to a protected page. We prevent the read system + * call from doing so. It is the clients responsibility to + * make sure that other system calls are similarly protected + * or write only to the stack. + * GWW_VDB: Use the Win32 GetWriteWatch functions, if available, to + * read dirty bits.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this.

For a more customized build, see the output of +`./configure --help`. To build it from the development repository, +`./autogen.sh` should be executed first. + +Alternatively, CMake could be use to build this package, e.g. +`cmake . && cmake --build .` in this directory should work. + +Note that much of the content of this library is in the header files. +However, two small libraries are built and installed: + +* `libatomic_ops.a` is a support (core) library, which is not needed on some + platforms. This is intended to be usable, under some mild restrictions, + in free or proprietary code, as are all the header files. + See [LICENSE](LICENSE) for more details about the licensing. + +* `libatomic_ops_gpl.a` is a so called gpl extension library containing some + higher level facilities. This code is covered by the GPL. The contents + correspond to the headers `atomic_ops_malloc.h` and `atomic_ops_stack.h`. + Not built and not installed if `--disable-gpl` option is passed to + `configure` (or if `-Denable_gpl=OFF` option is passed to `cmake` if the + latter is used to build the package).

This is an attempt to replace various existing files with +similar goals, since they usually do not handle differences in memory +barrier styles with sufficient generality. + +If this is included after defining AO_REQUIRE_CAS, then the package makes +an attempt to emulate [fetch_]compare_and_swap* (single-width) in a way that, +at least on Linux, should still be async-signal-safe. As a result, most +other atomic operations may then be defined using the compare-and-swap +emulation. This emulation is slow, since it needs to disable signals. +And it needs to block in case of contention. If you care about performance +on a platform that can't directly provide compare-and-swap, there are +probably better alternatives. But this allows easy ports to some such +platforms (e.g. PA_RISC). The option is ignored if compare-and-swap +can be implemented directly. + +If atomic_ops.h is included after defining AO_USE_PTHREAD_DEFS, then all +atomic operations will be emulated with pthread locking. This is NOT +async-signal-safe. And it is slow. It is intended primarily for debugging +of the atomic_ops package itself. + +Note that the implementation reflects our understanding of real processor +behavior. This occasionally diverges from the documented behavior. (E.g. +the documented X86 behavior seems to be weak enough that it is impractical +to use. Current real implementations appear to be much better behaved.) +We of course are in no position to guarantee that future processors +(even HPs) will continue to behave this way, though we hope they will. + +Corrections/additions for other platforms are greatly appreciated. + +OPERATIONS: + +Most operations handle values of type AO_t, which are unsigned integers +whose size matches that of pointers on the given architecture. Additionally, +on most supported architectures the operations are also implemented to handle +smaller integers types; such operations are indicated by the appropriate size +prefix: +- char_... Operates on unsigned char values; +- short_... Operates on unsigned short values; +- int_... Operates on unsigned int values. + +The notable exception is AO_test_and_set operating only on AO_TS_t, which is +whatever size the hardware supports with good performance. In some cases this +is the length of a cache line, in some other cases it is a byte. In many +cases AO_TS_t is equivalent to AO_t. + +The defined operations are all of the form AO_[](). + +The component specifies an atomic memory operation. It may be +one of the following, where the corresponding argument and result types +are also specified: + +void nop() + No atomic operation. The barrier may still be useful. +AO_t load(const volatile AO_t * addr) + Atomic load of *addr. +void store(volatile AO_t * addr, AO_t new_val) + Atomically store new_val to *addr. +AO_t fetch_and_add(volatile AO_t *addr, AO_t incr) + Atomically add incr to *addr, and return the original value of *addr. +AO_t fetch_and_add1(volatile AO_t *addr) + Equivalent to AO_fetch_and_add(addr, 1). +AO_t fetch_and_sub1(volatile AO_t *addr) + Equivalent to AO_fetch_and_add(addr, (AO_t)(-1)). +void and(volatile AO_t *addr, AO_t value) + Atomically 'and' value into *addr. +void or(volatile AO_t *addr, AO_t value) + Atomically 'or' value into *addr. +void xor(volatile AO_t *addr, AO_t value) + Atomically 'xor' value into *addr. +int compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) + Atomically compare *addr to old_val, and replace *addr by new_val + if the first comparison succeeds; returns nonzero if the comparison + succeeded and *addr was updated; cannot fail spuriously. +AO_t fetch_compare_and_swap(volatile AO_t * addr, AO_t old_val, AO_t new_val) + Atomically compare *addr to old_val, and replace *addr by new_val + if the first comparison succeeds; returns the original value of *addr; + cannot fail spuriously. +AO_TS_VAL_t test_and_set(volatile AO_TS_t * addr) + Atomically read the binary value at *addr, and set it. AO_TS_VAL_t + is an enumeration type which includes two values AO_TS_SET and + AO_TS_CLEAR. An AO_TS_t location is capable of holding an + AO_TS_VAL_t, but may be much larger, as dictated by hardware + constraints. Test_and_set logically sets the value to AO_TS_SET. + It may be reset to AO_TS_CLEAR with the AO_CLEAR(AO_TS_t *) macro. + AO_TS_t locations should be initialized to AO_TS_INITIALIZER. + The values of AO_TS_SET and AO_TS_CLEAR are hardware dependent. + (On PA-RISC, AO_TS_SET is zero!) + +Test_and_set is a more limited version of compare_and_swap. Its only +advantage is that it is more easily implementable on some hardware. It +should thus be used if only binary test-and-set functionality is needed. + +If available, we also provide compare_and_swap operations that operate +on wider values. Since standard data types for double width values +may not be available, these explicitly take pairs of arguments for the +new and/or old value. Unfortunately, there are two common variants, +neither of which can easily and efficiently emulate the other. +The first performs a comparison against the entire value being replaced, +where the second replaces a double-width replacement, but performs +a single-width comparison: + +int compare_double_and_swap_double(volatile AO_double_t * addr, + AO_t old_val1, AO_t old_val2, + AO_t new_val1, AO_t new_val2); + +int compare_and_swap_double(volatile AO_double_t * addr, + AO_t old_val1, + AO_t new_val1, AO_t new_val2); + +where AO_double_t is a structure containing AO_val1 and AO_val2 fields, +both of type AO_t. For compare_and_swap_double, we compare against +the val1 field. AO_double_t exists only if AO_HAVE_double_t +is defined. If this type is available then the following operation is +provided for convenience, fully equivalent to compare_double_and_swap_double: + +int double_compare_and_swap(volatile AO_double_t * addr, + AO_double_t old_val, AO_double_t new_val) + +Please note that AO_double_t (and AO_stack_t) variables should be properly +aligned (8-byte alignment on 32-bit targets, 16-byte alignment on 64-bit ones) +otherwise the behavior of a double-wide atomic primitive might be undefined +(or an assertion violation might occur) if such a misaligned variable is +passed (as a reference) to the primitive. Global and static variables should +already have proper alignment automatically but automatic variables (i.e. +located on the stack) might be misaligned because the stack might be +word-aligned (e.g. 4-byte stack alignment is the default one for x86). +Luckily, stack-allocated AO variables operated atomically are used rarely +in practice. + +ORDERING CONSTRAINTS: + +Each operation name also includes a suffix that specifies the associated +ordering semantics. The ordering constraint limits reordering of this +operation with respect to other atomic operations and ordinary memory +references. The current implementation assumes that all memory references +are to ordinary cacheable memory; the ordering guarantee is with respect +to other threads or processes, not I/O devices. (Whether or not this +distinction is important is platform-dependent.) + +Ordering suffixes are one of the following: + +: No memory barrier. A plain AO_nop() really does nothing. +_release: Earlier operations must become visible to other threads + before the atomic operation. +_acquire: Later operations must become visible after this operation. +_read: Subsequent reads must become visible after reads included in + the atomic operation or preceding it. Rarely useful for clients? +_write: Earlier writes become visible before writes during or after + the atomic operation. Rarely useful for clients? +_full: The associated operation is ordered with respect to both earlier and + later memory ops. If the associated operation is nop, then this orders + all earlier memory operations with respect to subsequent ones. + AO_store_full or AO_nop_full are the normal ways to force a store + to be ordered with respect to a later load. +_release_write: Ordered with respect to earlier writes. This is + normally implemented as either a _write or _release + barrier. +_acquire_read: Ordered with respect to later reads. This is + normally implemented as either a _read or _acquire barrier. +_dd_acquire_read: Ordered with respect to later reads that are data + dependent on this one. This is needed on + a pointer read, which is later dereferenced to read a + second value, with the expectation that the second + read is ordered after the first one. On most architectures, + this is equivalent to no barrier. (This is very + hard to define precisely. It should probably be avoided. + A major problem is that optimizers tend to try to + eliminate dependencies from the generated code, since + dependencies force the hardware to execute the code + serially.) + +We assume that if a store is data-dependent on a previous load, then +the two are always implicitly ordered. + +It is possible to test whether AO_[] is available on the +target platform by checking whether AO_HAVE_[] is defined +as a macro. + +Note that we generally don't implement operations that are either +meaningless (e.g. AO_nop_acquire, AO_nop_release) or which appear to +have no clear use (e.g. AO_load_release, AO_store_acquire, AO_load_write, +AO_store_read). On some platforms (e.g. PA-RISC) many operations +will remain undefined unless AO_REQUIRE_CAS is defined before including +the package. + +When typed in the package build directory, the following command +will print operations that are unimplemented on the platform: + +make test_atomic; ./test_atomic + +The following command generates a file "list_atomic.i" containing the +macro expansions of all implemented operations on the platform: + +make list_atomic.i + +Known issues include: + +We should be more precise in defining the semantics of the ordering +constraints, and if and how we can guarantee sequential consistency. + +Dd_acquire_read is very hard or impossible to define in a way that cannot +be invalidated by reasonably standard compiler transformations. + +Example: + +If you want to initialize an object, and then "publish" a pointer to it +in a global location p, such that other threads reading the new value of +p are guaranteed to see an initialized object, it suffices to use +AO_release_write(p, ...) to write the pointer to the object, and to +retrieve it in other threads with AO_acquire_read(p). + +Platform notes: + +All X86: We quietly assume 486 or better. + +Gcc on x86: +Define AO_USE_PENTIUM4_INSTRS to use the Pentium 4 mfence instruction. +Currently this is appears to be of marginal benefit. diff --git a/graphics/asymptote/libatomic_ops/README_malloc.txt b/graphics/asymptote/libatomic_ops/README_malloc.txt new file mode 100644 index 0000000000..7f741f2fce --- /dev/null +++ b/graphics/asymptote/libatomic_ops/README_malloc.txt @@ -0,0 +1,60 @@ +The atomic_ops_gpl includes a simple almost-lock-free malloc implementation. + +Note that the AO malloc implementation is licensed under the GPL, unlike the +lower level routines. + +This is intended as a safe way to allocate memory from a signal handler, +or to allocate memory in the context of a library that does not know what +thread library it will be used with.
