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 Library 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. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) 19yy name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs. If your program is a subroutine library, you may -consider it more useful to permit linking proprietary applications with the -library. If this is what you want to do, use the GNU Library General -Public License instead of this License. diff --git a/Build/source/utils/gzip/ChangeLog b/Build/source/utils/gzip/ChangeLog deleted file mode 100644 index 7dd0f865165..00000000000 --- a/Build/source/utils/gzip/ChangeLog +++ /dev/null @@ -1,587 +0,0 @@ -Wed Aug 18 09:34:23 1993 Jean-loup Gailly (jloup@chorus.fr) - - * version 1.2.4 - By default, do not restore file name and timestamp from those saved - inside the .gz file (behave as 'compress').

In some packages it creates a C header file containing -system-dependent definitions. It also creates a file `config.status' -that you can run in the future to recreate the current configuration. - -Running `configure' takes a minute or two. While it is running, it -prints some messages that tell what it is doing. If you don't want to -see the messages, run `configure' with its standard output redirected -to `/dev/null'; for example, `./configure >/dev/null'. - -To compile the package in a different directory from the one -containing the source code, you must use a version of `make' that -supports the VPATH variable, such as GNU `make'. `cd' to the directory -where you want the object files and executables to go and run -`configure'. `configure' automatically checks for the source code in -the directory that `configure' is in and in `..'. If for some reason -`configure' is not in the source code directory that you are -configuring, then it will report that it can't find the source code. -In that case, run `configure' with the option `--srcdir=DIR', where -DIR is the directory that contains the source code. - -By default, `make install' will install the package's files in -/usr/local/bin, /usr/local/lib, /usr/local/man, etc. You can specify an -installation prefix other than /usr/local by giving `configure' the option -`--prefix=PATH'. Alternately, you can do so by consistently giving a value -for the `prefix' variable when you run `make', e.g., - make prefix=/usr/gnu - make prefix=/usr/gnu install - -You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If -you give `configure' the option `--exec-prefix=PATH' or set the -`make' variable `exec_prefix' to PATH, the package will use PATH as -the prefix for installing programs and libraries. Data files and -documentation will still use the regular prefix. Normally, all files -are installed using the regular prefix. - -Another `configure' option is useful mainly in `Makefile' rules for -updating `config.status' and `Makefile'. The `--no-create' option -figures out the configuration for your system and records it in -`config.status', without actually configuring the package (creating -`Makefile's and perhaps a configuration header file). Later, you can -run `./config.status' to actually configure the package.

If you want to run them, -type `make check'. - -4. Type `make install' to install programs, data files, and -documentation. This creates links between gzip, gunzip and zcat. -You can create additional links uncompress, ungzip and gzcat if -you prefer these names. You can also create links to unpack and pcat -if your system uses packed files by default and you want to transform -them transparently to gzip'ed files. - -If you wish to use only the name gzcat and not overwrite an existing zcat, use: - - make ZCAT=gzcat install - -The man pages are installed by default with an extension `.1' (one). -If you want the extension `.l' (lower case L) use: - - make manext=l install - -If you are using csh or tcsh, you must type `rehash' after `make install' -to make sure that the command `gzip' will invoke the new executable. - -5.

Use "cc -O" instead. - -- There is an optimization bug in the IRIX 4.0.5 IDO 4.1 assembler which is - triggered by GCC -O. IDO 4.1.1 should fix this. If you have to use IDO 4.1 - then you can avoid the bug in one of the following ways: - - 1. Use SGI CC - 2. Add the -noasmopt flag to GCC - 3. Reconfigure GCC with the "mips-sgi-irix4loser" target which effectively - does the same as specifying "-noasmopt" all by default. - 4. Don't use -O at all with GCC. - -- On Solaris 2.1 for x86, the January 1993 "OEM" compiler release - generates bad code. This is fixed in the June 1993 "FCS" release. - -- on Sparc with SunOS 4.1.1 and the SC1.0 compiler, the optimizer - works up to -O3 but -O4 does not work. - -- MSC 5.1 with -Ox and -DDYN_ALLOC generates bad code in inflate.c. - The default is static allocation (no DYN_ALLOC) and -Ox works on inflate.c. - But -Ox does not work on util.c and unlzh.c, so you must use -Oait -Gs. - -- The exit() function in Turbo C++ 1.0 seems to be broken. gzip crashes - even if exit(0) is the first statement in main(). The problem is avoided - by adding -Dexit=_exit to CFLAGS in Makefile.bor. - -- On dnix 5.3 2.2 cc version 2.37c is buggy. Version 2.38d works. - -- On an Alliant running Concentrix, cc (even without optimization) generates - incorrect code. You have to use gcc. - -- On Cray running CSOS 1.0 with compiler version dev-125, you must compile - with the flag "-hnoopt" to avoid an optimizer bug. - -- On HPUX, configure can't find a correct install.

See the section "Special -targets" at the end of the INSTALL file for a list of known problems. -For all machines, use "make check" to check that gzip was compiled -correctly.

It recognizes automatically encrypted and compressed -files when they are first visited or written. It is available via -anonymous ftp to roebling.poly.edu [128.238.5.31] in /pub/crypt++.el. -The same directory contains also patches to dired, ange-ftp and info. -GNU tar 1.11.2 has a -z option to invoke directly gzip, so you don't have to -patch it. The package ftp.uu.net:/languages/emacs-lisp/misc/jka-compr19.el.Z -also supports gzip'ed files. - -The znew and gzexe shell scripts provided with gzip benefit from -(but do not require) the cpmod utility to transfer file attributes. -It is available by anonymous ftp on gatekeeper.dec.com in -/.0/usenet/comp.sources.unix/volume11/cpmod.Z. - -The sample programs zread.c, sub.c and add.c in subdirectory sample -are provided as examples of useful complements to gzip.

If -you are getting gzip for the first time, you can ask for a tar.Z file -instead of the much larger tar file. - -Many thanks to those who provided me with bug reports and feedback. -See the files THANKS and ChangeLog for more details. - - - Note about zip vs. gzip: - -The name 'gzip' was a very unfortunate choice, because zip and gzip -are two really different programs, although the actual compression and -decompression sources were written by the same persons. A different -name should have been used for gzip, but it is too late to change now. - -zip is an archiver: it compresses several files into a single archive -file. gzip is a simple compressor: each file is compressed separately. -Both share the same compression and decompression code for the -'deflate' method. unzip can also decompress old zip archives -(implode, shrink and reduce methods). gunzip can also decompress files -created by compress and pack. zip 1.9 and gzip do not support -compression methods other than deflation. (zip 1.0 supports shrink and -implode). Better compression methods may be added in future versions -of gzip. zip will always stick to absolute compatibility with pkzip, -it is thus constrained by PKWare, which is a commercial company. The -gzip header format is deliberately different from that of pkzip to -avoid such a constraint. - -On Unix, gzip is mostly useful in combination with tar. GNU tar -1.11.2 has a -z option to invoke gzip automatically. "tar -z" -compresses better than zip, since gzip can then take advantage of -redundancy between distinct files. The drawback is that you must -scan the whole tar.gz file in order to extract a single file near -the end; unzip can directly seek to the end of the zip file. There -is no overhead when you extract the whole archive anyway. -If a member of a .zip archive is damaged, other files can still -be recovered. If a .tar.gz file is damaged, files beyond the failure -point cannot be recovered. (Future versions of gzip will have -error recovery features.) - -gzip and gunzip are distributed as a single program. zip and unzip -are, for historical reasons, two separate programs, although the -authors of these two programs work closely together in the info-zip -team. zip and unzip are not associated with the GNU project. -The sources are available by ftp in - - oak.oakland.edu:/pub/misc/unix/zip19p1.zip - oak.oakland.edu:/pub/misc/unix/unz50p1.tar-z diff --git a/Build/source/utils/gzip/THANKS b/Build/source/utils/gzip/THANKS deleted file mode 100644 index dd8f7bfd8b3..00000000000 --- a/Build/source/utils/gzip/THANKS +++ /dev/null @@ -1,276 +0,0 @@ -gzip was written by Jean-loup Gailly <gzip@gnu.org>, with portions -written by Mark Adler (inflate.c), Peter Jannesen (unlzw.c) and -Haruhiko Okumura (unlzh.c).

Algorithm - -The deflation algorithm used by zip and gzip is a variation of LZ77 -(Lempel-Ziv 1977, see reference below). It finds duplicated strings in -the input data. The second occurrence of a string is replaced by a -pointer to the previous string, in the form of a pair (distance, -length). Distances are limited to 32K bytes, and lengths are limited -to 258 bytes. When a string does not occur anywhere in the previous -32K bytes, it is emitted as a sequence of literal bytes. (In this -description, 'string' must be taken as an arbitrary sequence of bytes, -and is not restricted to printable characters.) - -Literals or match lengths are compressed with one Huffman tree, and -match distances are compressed with another tree. The trees are stored -in a compact form at the start of each block. The blocks can have any -size (except that the compressed data for one block must fit in -available memory). A block is terminated when zip determines that it -would be useful to start another block with fresh trees. (This is -somewhat similar to compress.) - -Duplicated strings are found using a hash table. All input strings of -length 3 are inserted in the hash table. A hash index is computed for -the next 3 bytes. If the hash chain for this index is not empty, all -strings in the chain are compared with the current input string, and -the longest match is selected. - -The hash chains are searched starting with the most recent strings, to -favor small distances and thus take advantage of the Huffman encoding. -The hash chains are singly linked. There are no deletions from the -hash chains, the algorithm simply discards matches that are too old. - -To avoid a worst-case situation, very long hash chains are arbitrarily -truncated at a certain length, determined by a runtime option (zip -1 -to -9). So zip does not always find the longest possible match but -generally finds a match which is long enough. - -zip also defers the selection of matches with a lazy evaluation -mechanism. After a match of length N has been found, zip searches for a -longer match at the next input byte. If a longer match is found, the -previous match is truncated to a length of one (thus producing a single -literal byte) and the longer match is emitted afterwards. Otherwise, -the original match is kept, and the next match search is attempted only -N steps later. - -The lazy match evaluation is also subject to a runtime parameter. If -the current match is long enough, zip reduces the search for a longer -match, thus speeding up the whole process. If compression ratio is more -important than speed, zip attempts a complete second search even if -the first match is already long enough. - -The lazy match evaluation is not performed for the fastest compression -modes (speed options -1 to -3). For these fast modes, new strings -are inserted in the hash table only when no match was found, or -when the match is not too long. This degrades the compression ratio -but saves time since there are both fewer insertions and fewer searches. - - -2. gzip file format - -The pkzip format imposes a lot of overhead in various headers, which -are useful for an archiver but not necessary when only one file is -compressed. gzip uses a much simpler structure. Numbers are in little -endian format, and bit 0 is the least significant bit. -A gzip file is a sequence of compressed members. Each member has the -following structure: - -2 bytes magic header 0x1f, 0x8b (\037 \213) -1 byte compression method (0..7 reserved, 8 = deflate) -1 byte flags - bit 0 set: file probably ascii text - bit 1 set: continuation of multi-part gzip file - bit 2 set: extra field present - bit 3 set: original file name present - bit 4 set: file comment present - bit 5 set: file is encrypted - bit 6,7: reserved -4 bytes file modification time in Unix format -1 byte extra flags (depend on compression method) -1 byte operating system on which compression took place - -2 bytes optional part number (second part=1) -2 bytes optional extra field length -? bytes optional extra field -? bytes optional original file name, zero terminated -? bytes optional file comment, zero terminated -12 bytes optional encryption header -? bytes compressed data -4 bytes crc32 -4 bytes uncompressed input size modulo 2^32 - -The format was designed to allow single pass compression without any -backwards seek, and without a priori knowledge of the uncompressed -input size or the available size on the output media. If input does -not come from a regular disk file, the file modification time is set -to the time at which compression started. - -The time stamp is useful mainly when one gzip file is transferred over -a network. In this case it would not help to keep ownership -attributes. In the local case, the ownership attributes are preserved -by gzip when compressing/decompressing the file. A time stamp of zero -is ignored. - -Bit 0 in the flags is only an optional indication, which can be set by -a small lookahead in the input data. In case of doubt, the flag is -cleared indicating binary data. For systems which have different -file formats for ascii text and binary data, the decompressor can -use the flag to choose the appropriate format. - -The extra field, if present, must consist of one or more subfields, -each with the following format: - - subfield id : 2 bytes - subfield size : 2 bytes (little-endian format) - subfield data - -The subfield id can consist of two letters with some mnemonic value. -Please send any such id to <gzip@gnu.org>. Ids with a zero second -byte are reserved for future use. The following ids are defined: - - Ap (0x41, 0x70) : Apollo file type information - -The subfield size is the size of the subfield data and does not -include the id and the size itself. The field 'extra field length' is -the total size of the extra field, including subfield ids and sizes. - -It must be possible to detect the end of the compressed data with any -compression format, regardless of the actual size of the compressed -data. If the compressed data cannot fit in one file (in particular for -diskettes), each part starts with a header as described above, but -only the last part has the crc32 and uncompressed size. A decompressor -may prompt for additional data for multipart compressed files. It is -desirable but not mandatory that multiple parts be extractable -independently so that partial data can be recovered if one of the -parts is damaged. This is possible only if no compression state is -kept from one part to the other. The compression-type dependent flags -can indicate this. - -If the file being compressed is on a file system with case insensitive -names, the original name field must be forced to lower case. There is -no original file name if the data was compressed from standard input. - -Compression is always performed, even if the compressed file is -slightly larger than the original. The worst case expansion is -a few bytes for the gzip file header, plus 5 bytes every 32K block, -or an expansion ratio of 0.015% for large files. Note that the actual -number of used disk blocks almost never increases. - -The encryption is that of zip 1.9. For the encryption check, the -last byte of the decoded encryption header must be zero. The time -stamp of an encrypted file might be set to zero to avoid giving a clue -about the construction of the random header. - -Jean-loup Gailly -gzip@gnu.org - -References: - -[LZ77] Ziv J., Lempel A., "A Universal Algorithm for Sequential Data -Compression", IEEE Transactions on Information Theory", Vol. 23, No. 3, -pp. 337-343. - -APPNOTE.TXT documentation file in PKZIP 1.93a.

Insertions are performed at each input character, whereas - * string matches are performed only when the previous match ends. So it - * is preferable to spend more time in matches to allow very fast string - * insertions and avoid deletions. The matching algorithm for small - * strings is inspired from that of Rabin & Karp. A brute force approach - * is used to find longer strings when a small match has been found. - * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze - * (by Leonid Broukhis). - * A previous version of this file used a more sophisticated algorithm - * (by Fiala and Greene) which is guaranteed to run in linear amortized - * time, but has a larger average cost, uses more memory and is patented. - * However the F&G algorithm may be faster for some highly redundant - * files if the parameter max_chain_length (described below) is too large. - * - * ACKNOWLEDGEMENTS - * - * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and - * I found it in 'freeze' written by Leonid Broukhis. - * Thanks to many info-zippers for bug reports and testing. - * - * REFERENCES - * - * APPNOTE.TXT documentation file in PKZIP 1.93a distribution. - * - * A description of the Rabin and Karp algorithm is given in the book - * "Algorithms" by R.

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. - -@iftex -@unnumberedsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end iftex -@ifinfo -@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION -@end ifinfo - -@enumerate -@item -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. - -@item -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. - -@item -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: - -@enumerate a -@item -You must cause the modified files to carry prominent notices -stating that you changed the files and the date of any change. - -@item -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. - -@item -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.) -@end enumerate - -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. - -@item -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: - -@enumerate a -@item -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, - -@item -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, - -@item -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.) -@end enumerate - -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. - -@item -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. - -@item -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. - -@item -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.

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. - -@item -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. - -@item -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. - -@item -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 example, if file names are limited -to 14 characters, gzip.msdos.exe is compressed to gzi.msd.exe.gz. -Names are not truncated on systems which do not have a limit on file name -length. -.PP -By default, -.I gzip -keeps the original file name and timestamp in the compressed file. These -are used when decompressing the file with the -.B \-N -option. This is useful when the compressed file name was truncated or -when the time stamp was not preserved after a file transfer. -.PP -Compressed files can be restored to their original form using -.I gzip -d -or -.I gunzip -or -.I zcat. -If the original name saved in the compressed file is not suitable for its -file system, a new name is constructed from the original one to make it -legal. -.PP -.I gunzip -takes a list of files on its command line and replaces each -file whose name ends with .gz, -gz, .z, -z, _z or .Z -and which begins with the correct magic number with an uncompressed -file without the original extension. -.I gunzip -also recognizes the special extensions -.B "\&.tgz" -and -.B "\&.taz" -as shorthands for -.B "\&.tar.gz" -and -.B "\&.tar.Z" -respectively. -When compressing, -.I gzip -uses the -.B "\&.tgz" -extension if necessary instead of truncating a file with a -.B "\&.tar" -extension. -.PP -.I gunzip -can currently decompress files created by -.I gzip, zip, compress, compress -H -or -.I pack. -The detection of the input format is automatic. When using -the first two formats, -.I gunzip -checks a 32 bit CRC. For -.I pack, gunzip -checks the uncompressed length. The standard -.I compress -format was not designed to allow consistency checks. However -.I gunzip -is sometimes able to detect a bad .Z file. If you get an error -when uncompressing a .Z file, do not assume that the .Z file is -correct simply because the standard -.I uncompress -does not complain. This generally means that the standard -.I uncompress -does not check its input, and happily generates garbage output. -The SCO compress -H format (lzh compression method) does not include a CRC -but also allows some consistency checks. -.PP -Files created by -.I zip -can be uncompressed by gzip only if they have a single member compressed -with the 'deflation' method.

However, -you can get better compression by compressing all members at once: - - cat file1 file2 | gzip > foo.gz - -compresses better than - - gzip -c file1 file2 > foo.gz - -If you want to recompress concatenated files to get better compression, do: - - gzip -cd old.gz | gzip > new.gz - -If a compressed file consists of several members, the uncompressed -size and CRC reported by the --list option applies to the last member -only. If you need the uncompressed size for all members, you can use: - - gzip -cd file.gz | wc -c - -If you wish to create a single archive file with multiple members so -that members can later be extracted independently, use an archiver -such as tar or zip. GNU tar supports the -z option to invoke gzip -transparently. gzip is designed as a complement to tar, not as a -replacement. -.SH "ENVIRONMENT" -The environment variable -.B GZIP -can hold a set of default options for -.I gzip. -These options are interpreted first and can be overwritten by -explicit command line parameters. For example: - for sh: GZIP="-8v --name"; export GZIP - for csh: setenv GZIP "-8v --name" - for MSDOS: set GZIP=-8v --name - -On Vax/VMS, the name of the environment variable is GZIP_OPT, to -avoid a conflict with the symbol set for invocation of the program. -.SH "SEE ALSO" -znew(1), zcmp(1), zmore(1), zforce(1), gzexe(1), zip(1), unzip(1), compress(1), -pack(1), compact(1) -.SH "DIAGNOSTICS" -Exit status is normally 0; -if an error occurs, exit status is 1.

Use the -.B \-f -flag to force compression of multiply-linked files. -.in -8 -.SH CAVEATS -When writing compressed data to a tape, it is generally necessary to -pad the output with zeroes up to a block boundary. When the data is -read and the whole block is passed to -.I gunzip -for decompression, -.I gunzip -detects that there is extra trailing garbage after the compressed data -and emits a warning by default. You have to use the --quiet option to -suppress the warning. This option can be set in the -.B GZIP -environment variable as in: - for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 - for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0 - -In the above example, gzip is invoked implicitly by the -z option of -GNU tar. Make sure that the same block size (-b option of tar) is used -for reading and writing compressed data on tapes. (This example -assumes you are using the GNU version of tar.) -.SH BUGS -The --list option reports incorrect sizes if they exceed 2 gigabytes. -The --list option reports sizes as -1 and crc as ffffffff if the -compressed file is on a non seekable media. - -In some rare cases, the --best option gives worse compression than -the default compression level (-6).

Whenever possible, each file is replaced by - one with the extension .gz, while keeping the same ownership - modes, access and modification times. (The default exten- - sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT - and Atari.) If no files are specified, or if a file name is - "-", the standard input is compressed to the standard out- - put. Gzip will only attempt to compress regular files. In - particular, it will ignore symbolic links. - - If the compressed file name is too long for its file system, - gzip truncates it. Gzip attempts to truncate only the parts - of the file name longer than 3 characters. (A part is del- - imited by dots.) If the name consists of small parts only, - the longest parts are truncated. For example, if file names - are limited to 14 characters, gzip.msdos.exe is compressed - to gzi.msd.exe.gz. Names are not truncated on systems which - do not have a limit on file name length. - - By default, gzip keeps the original file name and timestamp - in the compressed file. These are used when decompressing - the file with the -N option. This is useful when the - compressed file name was truncated or when the time stamp - was not preserved after a file transfer. - - Compressed files can be restored to their original form - using gzip -d or gunzip or zcat. If the original name saved - in the compressed file is not suitable for its file system, - a new name is constructed from the original one to make it - legal. - - gunzip takes a list of files on its command line and - replaces each file whose name ends with .gz, -gz, .z, -z, _z - or .Z and which begins with the correct magic number with an - uncompressed file without the original extension. gunzip - also recognizes the special extensions .tgz and .taz as - shorthands for .tar.gz and .tar.Z respectively. When - compressing, gzip uses the .tgz extension if necessary - instead of truncating a file with a .tar extension. - - gunzip can currently decompress files created by gzip, zip, - compress, compress -H or pack. The detection of the input - format is automatic. When using the first two formats, - gunzip checks a 32 bit CRC. For pack, gunzip checks the - uncompressed length. The standard compress format was not - designed to allow consistency checks. However gunzip is - sometimes able to detect a bad .Z file. If you get an error - when uncompressing a .Z file, do not assume that the .Z file - is correct simply because the standard uncompress does not - complain. This generally means that the standard uncompress - does not check its input, and happily generates garbage out- - put. The SCO compress -H format (lzh compression method) - does not include a CRC but also allows some consistency - checks. - - Files created by zip can be uncompressed by gzip only if - they have a single member compressed with the 'deflation' - method. This feature is only intended to help conversion of - tar.zip files to the tar.gz format. To extract zip files - with several members, use unzip instead of gunzip. - - zcat is identical to gunzip -c. (On some systems, zcat may - be installed as gzcat to preserve the original link to - compress.) zcat uncompresses either a list of files on the - command line or its standard input and writes the - uncompressed data on standard output. zcat will uncompress - files that have the correct magic number whether they have a - .gz suffix or not. - - Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP. - The amount of compression obtained depends on the size of - the input and the distribution of common substrings. Typi- - cally, text such as source code or English is reduced by - 60-70%. Compression is generally much better than that - achieved by LZW (as used in compress), Huffman coding (as - used in pack), or adaptive Huffman coding (compact). - - Compression is always performed, even if the compressed file - is slightly larger than the original. The worst case expan- - sion is a few bytes for the gzip file header, plus 5 bytes - every 32K block, or an expansion ratio of 0.015% for large - files. Note that the actual number of used disk blocks - almost never increases. gzip preserves the mode, ownership - and timestamps of files when compressing or decompressing. - -OPTIONS - -a --ascii - Ascii text mode: convert end-of-lines using local con- - ventions. This option is supported only on some non- - Unix systems. For MSDOS, CR LF is converted to LF when - compressing, and LF is converted to CR LF when - decompressing. - - -c --stdout --to-stdout - Write output on standard output; keep original files - unchanged. If there are several input files, the out- - put consists of a sequence of independently compressed - members. To obtain better compression, concatenate all - input files before compressing them. - - -d --decompress --uncompress - Decompress. - - -f --force - Force compression or decompression even if the file has - multiple links or the corresponding file already - exists, or if the compressed data is read from or writ- - ten to a terminal. If the input data is not in a format - recognized by gzip, and if the option --stdout is also - given, copy the input data without change to the stan- - dard ouput: let zcat behave as cat. If -f is not given, - and when not running in the background, gzip prompts to - verify whether an existing file should be overwritten. - - -h --help - Display a help screen and quit. - - -l --list - For each compressed file, list the following fields: - - compressed size: size of the compressed file - uncompressed size: size of the uncompressed file - ratio: compression ratio (0.0% if unknown) - uncompressed_name: name of the uncompressed file - - The uncompressed size is given as -1 for files not in - gzip format, such as compressed .Z files. To get the - uncompressed size for such a file, you can use: - - zcat file.Z | wc -c - - In combination with the --verbose option, the following - fields are also displayed: - - method: compression method - crc: the 32-bit CRC of the uncompressed data - date & time: time stamp for the uncompressed file - - The compression methods currently supported are - deflate, compress, lzh (SCO compress -H) and pack. The - crc is given as ffffffff for a file not in gzip format. - - With --name, the uncompressed name, date and time are - those stored within the compress file if present. - - With --verbose, the size totals and compression ratio - for all files is also displayed, unless some sizes are - unknown. With --quiet, the title and totals lines are - not displayed. - - -L --license - Display the gzip license and quit. - - -n --no-name - When compressing, do not save the original file name - and time stamp by default. (The original name is always - saved if the name had to be truncated.) When - decompressing, do not restore the original file name if - present (remove only the gzip suffix from the - compressed file name) and do not restore the original - time stamp if present (copy it from the compressed - file). This option is the default when decompressing. - - -N --name - When compressing, always save the original file name - and time stamp; this is the default. When decompress- - ing, restore the original file name and time stamp if - present. This option is useful on systems which have a - limit on file name length or when the time stamp has - been lost after a file transfer. - - -q --quiet - Suppress all warnings. - - -r --recursive - Travel the directory structure recursively. If any of - the file names specified on the command line are direc- - tories, gzip will descend into the directory and - compress all the files it finds there (or decompress - them in the case of gunzip ). - - -S .suf --suffix .suf - Use suffix .suf instead of .gz. Any suffix can be - given, but suffixes other than .z and .gz should be - avoided to avoid confusion when files are transferred - to other systems. A null suffix forces gunzip to try - decompression on all given files regardless of suffix, - as in: - - gunzip -S "" * (*.* for MSDOS) - - Previous versions of gzip used the .z suffix. This was - changed to avoid a conflict with pack(1). - - -t --test - Test. Check the compressed file integrity. - - -v --verbose - Verbose. Display the name and percentage reduction for - each file compressed or decompressed. - - -V --version - Version. Display the version number and compilation - options then quit. - - -# --fast --best - Regulate the speed of compression using the specified - digit #, where -1 or --fast indicates the fastest - compression method (less compression) and -9 or --best - indicates the slowest compression method (best compres- - sion). The default compression level is -6 (that is, - biased towards high compression at expense of speed). - -ADVANCED USAGE - Multiple compressed files can be concatenated. In this case, - gunzip will extract all members at once. For example: - - gzip -c file1 > foo.gz - gzip -c file2 >> foo.gz - - Then - gunzip -c foo - - is equivalent to - - cat file1 file2 - - In case of damage to one member of a .gz file, other members - can still be recovered (if the damaged member is removed). - However, you can get better compression by compressing all - members at once: - - cat file1 file2 | gzip > foo.gz - - compresses better than - - gzip -c file1 file2 > foo.gz - - If you want to recompress concatenated files to get better - compression, do: - - gzip -cd old.gz | gzip > new.gz - - If a compressed file consists of several members, the - uncompressed size and CRC reported by the --list option - applies to the last member only. If you need the - uncompressed size for all members, you can use: - - gzip -cd file.gz | wc -c - - If you wish to create a single archive file with multiple - members so that members can later be extracted indepen- - dently, use an archiver such as tar or zip. GNU tar supports - the -z option to invoke gzip transparently. gzip is designed - as a complement to tar, not as a replacement. - -ENVIRONMENT - The environment variable GZIP can hold a set of default - options for gzip. These options are interpreted first and - can be overwritten by explicit command line parameters. For - example: - for sh: GZIP="-8v --name"; export GZIP - for csh: setenv GZIP "-8v --name" - for MSDOS: set GZIP=-8v --name - - On Vax/VMS, the name of the environment variable is - GZIP_OPT, to avoid a conflict with the symbol set for invo- - cation of the program. - -SEE ALSO - znew(1), zcmp(1), zmore(1), zforce(1), gzexe(1), zip(1), - unzip(1), compress(1), pack(1), compact(1) - -DIAGNOSTICS - Exit status is normally 0; if an error occurs, exit status - is 1. If a warning occurs, exit status is 2. - - Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...] - Invalid options were specified on the command line. - file: not in gzip format - The file specified to gunzip has not been - compressed. - file: Corrupt input. Use zcat to recover some data. - The compressed file has been damaged. The data up to - the point of failure can be recovered using - zcat file > recover - file: compressed with xx bits, can only handle yy bits - File was compressed (using LZW) by a program that - could deal with more bits than the decompress code - on this machine. Recompress the file with gzip, - which compresses better and uses less memory. - file: already has .gz suffix -- no change - The file is assumed to be already compressed. - Rename the file and try again. - file already exists; do you wish to overwrite (y or n)? - Respond "y" if you want the output file to be - replaced; "n" if not. - gunzip: corrupt input - A SIGSEGV violation was detected which usually means - that the input file has been corrupted. - xx.x% - Percentage of the input saved by compression. - (Relevant only for -v and -l.) - -- not a regular file or directory: ignored - When the input file is not a regular file or direc- - tory, (e.g. a symbolic link, socket, FIFO, device - file), it is left unaltered. - -- has xx other links: unchanged - The input file has links; it is left unchanged. See - ln(1) for more information. Use the -f flag to force - compression of multiply-linked files. - -CAVEATS - When writing compressed data to a tape, it is generally - necessary to pad the output with zeroes up to a block boun- - dary. When the data is read and the whole block is passed to - gunzip for decompression, gunzip detects that there is extra - trailing garbage after the compressed data and emits a warn- - ing by default. You have to use the --quiet option to - suppress the warning. This option can be set in the GZIP - environment variable as in: - for sh: GZIP="-q" tar -xfz --block-compress /dev/rst0 - for csh: (setenv GZIP -q; tar -xfz --block-compr /dev/rst0 - - In the above example, gzip is invoked implicitly by the -z - option of GNU tar. Make sure that the same block size (-b - option of tar) is used for reading and writing compressed - data on tapes. (This example assumes you are using the GNU - version of tar.) - -BUGS - The --list option reports incorrect sizes if they exceed 2 - gigabytes. The --list option reports sizes as -1 and crc as - ffffffff if the compressed file is on a non seekable media. - - In some rare cases, the --best option gives worse compres- - sion than the default compression level (-6). On some highly - redundant files, compress compresses better than gzip. diff --git a/Build/source/utils/gzip/gzip.h b/Build/source/utils/gzip/gzip.h deleted file mode 100644 index 25297ef4eb5..00000000000 --- a/Build/source/utils/gzip/gzip.h +++ /dev/null @@ -1,319 +0,0 @@ -/* gzip.h -- common declarations for all gzip modules - * Copyright (C) 1992-1993 Jean-loup Gailly. - * This is free software; you can redistribute it and/or modify it under the - * terms of the GNU General Public License, see the file COPYING. - */ - -#if defined(__STDC__) || defined(PROTO) -# define OF(args) args -#else -# define OF(args) () -#endif - -#ifdef __STDC__ - typedef void *voidp; -#else - typedef char *voidp; -#endif - -/* I don't like nested includes, but the string and io functions are used - * too often - */ -#include <stdio.h> -#if !defined(NO_STRING_H) || defined(STDC_HEADERS) -# include <string.h> -# if !defined(STDC_HEADERS) && !defined(NO_MEMORY_H) && !defined(__GNUC__) -# include <memory.h> -# endif -# define memzero(s, n) memset ((voidp)(s), 0, (n)) -#else -# include <strings.h> -# define strchr index -# define strrchr rindex -# define memcpy(d, s, n) bcopy((s), (d), (n)) -# define memcmp(s1, s2, n) bcmp((s1), (s2), (n)) -# define memzero(s, n) bzero((s), (n)) -#endif - -#ifndef RETSIGTYPE -# define RETSIGTYPE void -#endif - -#define local static - -typedef unsigned char uch; -typedef unsigned short ush; -typedef unsigned long ulg; - -/* Return codes from gzip */ -#define OK 0 -#define ERROR 1 -#define WARNING 2 - -/* Compression methods (see algorithm.doc) */ -#define STORED 0 -#define COMPRESSED 1 -#define PACKED 2 -#define LZHED 3 -/* methods 4 to 7 reserved */ -#define DEFLATED 8 -#define MAX_METHODS 9 -extern int method; /* compression method */ - -/* To save memory for 16 bit systems, some arrays are overlaid between - * the various modules: - * deflate: prev+head window d_buf l_buf outbuf - * unlzw: tab_prefix tab_suffix stack inbuf outbuf - * inflate: window inbuf - * unpack: window inbuf prefix_len - * unlzh: left+right window c_table inbuf c_len - * For compression, input is done in window[].

Whenever possible, each file is replaced by one with the -extension @samp{.gz}, while keeping the same ownership modes, access and -modification times. (The default extension is @samp{-gz} for VMS, -@samp{z} for MSDOS, OS/2 FAT and Atari.) If no files are specified or -if a file name is "-", the standard input is compressed to the standard -output. @code{gzip} will only attempt to compress regular files. In -particular, it will ignore symbolic links. - -If the new file name is too long for its file system, @code{gzip} -truncates it. @code{gzip} attempts to truncate only the parts of the -file name longer than 3 characters. (A part is delimited by dots.) If -the name consists of small parts only, the longest parts are truncated. -For example, if file names are limited to 14 characters, gzip.msdos.exe -is compressed to gzi.msd.exe.gz. Names are not truncated on systems -which do not have a limit on file name length. - -By default, @code{gzip} keeps the original file name and timestamp in -the compressed file. These are used when decompressing the file with the -@samp{-N} option. This is useful when the compressed file name was -truncated or when the time stamp was not preserved after a file -transfer. - -Compressed files can be restored to their original form using @samp{gzip -d} -or @code{gunzip} or @code{zcat}. If the original name saved in the -compressed file is not suitable for its file system, a new name is -constructed from the original one to make it legal. - -@code{gunzip} takes a list of files on its command line and replaces -each file whose name ends with @samp{.gz}, @samp{.z}, @samp{.Z}, -@samp{-gz}, @samp{-z} or @samp{_z} and which begins with the correct -magic number with an uncompressed file without the original extension. -@code{gunzip} also recognizes the special extensions @samp{.tgz} and -@samp{.taz} as shorthands for @samp{.tar.gz} and @samp{.tar.Z} -respectively. When compressing, @code{gzip} uses the @samp{.tgz} -extension if necessary instead of truncating a file with a @samp{.tar} -extension. - -@code{gunzip} can currently decompress files created by @code{gzip}, -@code{zip}, @code{compress} or @code{pack}. The detection of the input -format is automatic. When using the first two formats, @code{gunzip} -checks a 32 bit CRC (cyclic redundancy check). For @code{pack}, -@code{gunzip} checks the uncompressed length. The @code{compress} format -was not designed to allow consistency checks. However @code{gunzip} is -sometimes able to detect a bad @samp{.Z} file. If you get an error when -uncompressing a @samp{.Z} file, do not assume that the @samp{.Z} file is -correct simply because the standard @code{uncompress} does not complain. -This generally means that the standard @code{uncompress} does not check -its input, and happily generates garbage output. The SCO @samp{compress --H} format (@code{lzh} compression method) does not include a CRC but -also allows some consistency checks. - -Files created by @code{zip} can be uncompressed by @code{gzip} only if -they have a single member compressed with the 'deflation' method. This -feature is only intended to help conversion of @code{tar.zip} files to -the @code{tar.gz} format. To extract @code{zip} files with several -members, use @code{unzip} instead of @code{gunzip}. - -@code{zcat} is identical to @samp{gunzip -c}. @code{zcat} -uncompresses either a list of files on the command line or its standard -input and writes the uncompressed data on standard output. @code{zcat} -will uncompress files that have the correct magic number whether they -have a @samp{.gz} suffix or not. - -@code{gzip} uses the Lempel-Ziv algorithm used in @code{zip} and PKZIP. -The amount of compression obtained depends on the size of the input and -the distribution of common substrings. Typically, text such as source -code or English is reduced by 60-70%. Compression is generally much -better than that achieved by LZW (as used in @code{compress}), Huffman -coding (as used in @code{pack}), or adaptive Huffman coding -(@code{compact}). - -Compression is always performed, even if the compressed file is slightly -larger than the original. The worst case expansion is a few bytes for -the @code{gzip} file header, plus 5 bytes every 32K block, or an expansion -ratio of 0.015% for large files. Note that the actual number of used -disk blocks almost never increases. @code{gzip} preserves the mode, -ownership and timestamps of files when compressing or decompressing. - -@node Sample, Invoking gzip, Overview, Top -@chapter Sample Output -@cindex sample - -Here are some realistic examples of running @code{gzip}. - -This is the output of the command @samp{gzip -h}: - -@example -gzip 1.2.4 (18 Aug 93) -usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...] - -c --stdout write on standard output, keep original files unchanged - -d --decompress decompress - -f --force force overwrite of output file and compress links - -h --help give this help - -l --list list compressed file contents - -L --license display software license - -n --no-name do not save or restore the original name and time stamp - -N --name save or restore the original name and time stamp - -q --quiet suppress all warnings - -r --recursive operate recursively on directories - -S .suf --suffix .suf use suffix .suf on compressed files - -t --test test compressed file integrity - -v --verbose verbose mode - -V --version display version number - -1 --fast compress faster - -9 --best compress better - file... files to (de)compress.

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. - -<LI> - -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. - -<LI> - -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: - - -<OL> -<LI> - -You must cause the modified files to carry prominent notices -stating that you changed the files and the date of any change. - -<LI> - -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. - -<LI> - -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.) -</OL> - -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. - -<LI> - -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: - - -<OL> -<LI> - -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, - -<LI> - -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, - -<LI> - -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.) -</OL> - -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. - -<LI> - -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. - -<LI> - -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. - -<LI> - -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. - -<LI> - -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. - -<LI> - -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. - -<LI> - -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. - -<LI> - -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.

These are used when decompressing the file with the -<SAMP>`-N'</SAMP> option. This is useful when the compressed file name was -truncated or when the time stamp was not preserved after a file -transfer. - - -<P> -Compressed files can be restored to their original form using <SAMP>`gzip -d'</SAMP> -or <CODE>gunzip</CODE> or <CODE>zcat</CODE>. If the original name saved in the -compressed file is not suitable for its file system, a new name is -constructed from the original one to make it legal. - - -<P> -<CODE>gunzip</CODE> takes a list of files on its command line and replaces -each file whose name ends with <SAMP>`.gz'</SAMP>, <SAMP>`.z'</SAMP>, <SAMP>`.Z'</SAMP>, -<SAMP>`-gz'</SAMP>, <SAMP>`-z'</SAMP> or <SAMP>`_z'</SAMP> and which begins with the correct -magic number with an uncompressed file without the original extension. -<CODE>gunzip</CODE> also recognizes the special extensions <SAMP>`.tgz'</SAMP> and -<SAMP>`.taz'</SAMP> as shorthands for <SAMP>`.tar.gz'</SAMP> and <SAMP>`.tar.Z'</SAMP> -respectively. When compressing, <CODE>gzip</CODE> uses the <SAMP>`.tgz'</SAMP> -extension if necessary instead of truncating a file with a <SAMP>`.tar'</SAMP> -extension. - - -<P> -<CODE>gunzip</CODE> can currently decompress files created by <CODE>gzip</CODE>, -<CODE>zip</CODE>, <CODE>compress</CODE> or <CODE>pack</CODE>. The detection of the input -format is automatic. When using the first two formats, <CODE>gunzip</CODE> -checks a 32 bit CRC (cyclic redundancy check).

If you get an error when -uncompressing a <SAMP>`.Z'</SAMP> file, do not assume that the <SAMP>`.Z'</SAMP> file is -correct simply because the standard <CODE>uncompress</CODE> does not complain. -This generally means that the standard <CODE>uncompress</CODE> does not check -its input, and happily generates garbage output. The SCO <SAMP>`compress --H'</SAMP> format (<CODE>lzh</CODE> compression method) does not include a CRC but -also allows some consistency checks. - - -<P> -Files created by <CODE>zip</CODE> can be uncompressed by <CODE>gzip</CODE> only if -they have a single member compressed with the 'deflation' method. This -feature is only intended to help conversion of <CODE>tar.zip</CODE> files to -the <CODE>tar.gz</CODE> format.

The compression - method searches for as much of the current string of bytes (up to a - length of 258) in the previous 32K bytes. If it doesn't find any - matches (of at least length 3), it codes the next byte. Otherwise, it - codes the length of the matched string and its distance backwards from - the current position. There is a single Huffman code that codes both - single bytes (called "literals") and match lengths. A second Huffman - code codes the distance information, which follows a length code. Each - length or distance code actually represents a base value and a number - of "extra" (sometimes zero) bits to get to add to the base value. At - the end of each deflated block is a special end-of-block (EOB) literal/ - length code. The decoding process is basically: get a literal/length - code; if EOB then done; if a literal, emit the decoded byte; if a - length then get the distance and emit the referred-to bytes from the - sliding window of previously emitted data. - - There are (currently) three kinds of inflate blocks: stored, fixed, and - dynamic. The compressor deals with some chunk of data at a time, and - decides which method to use on a chunk-by-chunk basis. A chunk might - typically be 32K or 64K. If the chunk is uncompressible, then the - "stored" method is used. In this case, the bytes are simply stored as - is, eight bits per byte, with none of the above coding. The bytes are - preceded by a count, since there is no longer an EOB code. - - If the data is compressible, then either the fixed or dynamic methods - are used. In the dynamic method, the compressed data is preceded by - an encoding of the literal/length and distance Huffman codes that are - to be used to decode this block. The representation is itself Huffman - coded, and so is preceded by a description of that code. These code - descriptions take up a little space, and so for small blocks, there is - a predefined set of codes, called the fixed codes. The fixed method is - used if the block codes up smaller that way (usually for quite small - chunks), otherwise the dynamic method is used. In the latter case, the - codes are customized to the probabilities in the current block, and so - can code it much better than the pre-determined fixed codes. - - The Huffman codes themselves are decoded using a mutli-level table - lookup, in order to maximize the speed of decoding plus the speed of - building the decoding tables. See the comments below that precede the - lbits and dbits tuning parameters. - */ - - -/* - Notes beyond the 1.93a appnote.txt: - - 1. Distance pointers never point before the beginning of the output - stream. - 2. Distance pointers can point back across blocks, up to 32k away. - 3. There is an implied maximum of 7 bits for the bit length table and - 15 bits for the actual data. - 4. If only one code exists, then it is encoded using one bit. (Zero - would be more efficient, but perhaps a little confusing.) If two - codes exist, they are coded using one bit each (0 and 1). - 5. There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarly, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10. In the tree reconstruction algorithm, Code = Code + Increment - only if BitLength(i) is not zero. (Pretty obvious.) - 11. Correction: 4 Bits: # of Bit Length codes - 4 (4 - 19) - 12. Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths. It is possible (and advantageous) for - a repeat code (16, 17, or 18) to go across the boundary between - the two sets of lengths. - */ - -#ifdef RCSID -static char rcsid[] = "$Id: inflate.c,v 0.14 1993/06/10 13:27:04 jloup Exp $"; -#endif - -#include <sys/types.h> - -#include "tailor.h" - -#if defined(STDC_HEADERS) || !defined(NO_STDLIB_H) -# include <stdlib.h> -#endif - -#include "gzip.h" -#define slide window - -/* Huffman code lookup table entry--this entry is four bytes for machines - that have 16-bit pointers (e.g. PC's in the small or medium model). - Valid extra bits are 0..13. e == 15 is EOB (end of block), e == 16 - means that v is a literal, 16 < e < 32 means that v is a pointer to - the next table, which codes e - 16 bits, and lastly e == 99 indicates - an unused code.

Whenever possible, each file is replaced by - one with the extension .gz, while keeping the same ownership - modes, access and modification times. (The default exten- - sion is -gz for VMS, z for MSDOS, OS/2 FAT, Windows NT FAT - and Atari.) If no files are specified, or if a file name is - "-", the standard input is compressed to the standard out- - put. Gzip will only attempt to compress regular files. - - If the compressed file name is too long for its file system, - gzip truncates it. Gzip attempts to truncate only the parts - of the file name longer than 3 characters. (A part is del- - imited by dots.) If the name consists of small parts only, - the longest parts are truncated. For example, if file names - are limited to 14 characters, gzip.msdos.exe is compressed - to gzi.msd.exe.gz. Names are not truncated on systems which - do not have a limit on file name length. - - By default, gzip keeps the original file name and timestamp - in the compressed file. These are used when decompressing - the file with the -N option. This is useful when the - compressed file name was truncated or when the time stamp - was not preserved after a file transfer. - - Compressed files can be restored to their original form - using gzip -d or gunzip or zcat. If the original name saved - in the compressed file is not suitable for its file system, - a new name is constructed from the original one to make it - legal. - - gunzip takes a list of files on its command line and - replaces each file whose name ends with .gz, -gz, .z, -z, _z - or .Z and which begins with the correct magic number with an - uncompressed file without the original extension. gunzip - also recognizes the special extensions .tgz and .taz as - shorthands for .tar.gz and .tar.Z respectively. When - compressing, gzip uses the .tgz extension if necessary - instead of truncating a file with a .tar extension. - - gunzip can currently decompress files created by gzip, zip, - compress, compress -H or pack. The detection of the input - format is automatic. When using the first two formats, - gunzip checks a 32 bit CRC. For pack, gunzip checks the - uncompressed length. The standard compress format was not - designed to allow consistency checks. However gunzip is - sometimes able to detect a bad .Z file. If you get an error - when uncompressing a .Z file, do not assume that the .Z file - is correct simply because the standard uncompress does not - complain. This generally means that the standard uncompress - does not check its input, and happily generates garbage out- - put. The SCO compress -H format (lzh compression method) - does not include a CRC but also allows some consistency - checks. - - Files created by zip can be uncompressed by gzip only if - they have a single member compressed with the 'deflation' - method. This feature is only intended to help conversion of - tar.zip files to the tar.gz format. To extract zip files - with several members, use unzip instead of gunzip. - - zcat is identical to gunzip -c. (On some systems, zcat may - be installed as gzcat to preserve the original link to - compress.) zcat uncompresses either a list of files on the - command line or its standard input and writes the - uncompressed data on standard output. zcat will uncompress - files that have the correct magic number whether they have a - .gz suffix or not. - - Gzip uses the Lempel-Ziv algorithm used in zip and PKZIP. - The amount of compression obtained depends on the size of - the input and the distribution of common substrings. Typi- - cally, text such as source code or English is reduced by - 60-70%. Compression is generally much better than that - achieved by LZW (as used in compress), Huffman coding (as - used in pack), or adaptive Huffman coding (compact). - - Compression is always performed, even if the compressed file - is slightly larger than the original. The worst case expan- - sion is a few bytes for the gzip file header, plus 5 bytes - every 32K block, or an expansion ratio of 0.015% for large - files. Note that the actual number of used disk blocks - almost never increases. gzip preserves the mode, ownership - and timestamps of files when compressing or decompressing. - -2 OPTIONS - -a --ascii - Ascii text mode: convert end-of-lines using local con- - ventions. This option is supported only on some non- - Unix systems. For MSDOS, CR LF is converted to LF when - compressing, and LF is converted to CR LF when - decompressing. - - -c --stdout --to-stdout - Write output on standard output; keep original files - unchanged. If there are several input files, the out- - put consists of a sequence of independently compressed - members. To obtain better compression, concatenate all - input files before compressing them. - - -d --decompress --uncompress - Decompress. - - -f --force - Force compression or decompression even if the file has - multiple links or the corresponding file already - exists, or if the compressed data is read from or writ- - ten to a terminal. If the input data is not in a format - recognized by gzip, and if the option --stdout is also - given, copy the input data without change to the stan- - dard ouput: let zcat behave as cat. If -f is not given, - and when not running in the background, gzip prompts to - verify whether an existing file should be overwritten. - - -h --help - Display a help screen and quit. - - -l --list - For each compressed file, list the following fields: - - compressed size: size of the compressed file - uncompressed size: size of the uncompressed file - ratio: compression ratio (0.0% if unknown) - uncompressed_name: name of the uncompressed file - - The uncompressed size is given as -1 on VMS because it - it is not possible to seek reliably to the end of the - compressed file, where this size is stored. - - In combination with the --verbose option, the following - fields are also displayed: - - method: compression method - crc: the 32-bit CRC of the uncompressed data - date & time: time stamp for the uncompressed file - - The compression methods currently supported are - deflate, compress, lzh (SCO compress -H) and pack. The - crc is given as ffffffff on VMS for the reason given - above about the uncompressed size. - - With --name, the uncompressed name, date and time are - those stored within the compress file if present. - - With --verbose, the size totals and compression ratio - for all files is also displayed, unless some sizes are - unknown. With --quiet, the title and totals lines are - not displayed. - - -L --license - Display the gzip license and quit. - - -n --no-name - When compressing, do not save the original file name - and time stamp by default. (The original name is always - saved if the name had to be truncated.) When - decompressing, do not restore the original file name if - present (remove only the gzip suffix from the - compressed file name) and do not restore the original - time stamp if present (copy it from the compressed - file). This option is the default when decompressing. - - -N --name - When compressing, always save the original file name - and time stamp; this is the default. When decompress- - ing, restore the original file name and time stamp if - present. This option is useful on systems which have a - limit on file name length or when the time stamp has - been lost after a file transfer. - - -q --quiet - Suppress all warnings. - - -r --recursive - Travel the directory structure recursively. If any of - the file names specified on the command line are direc- - tories, gzip will descend into the directory and - compress all the files it finds there (or decompress - them in the case of gunzip ). - - -S suf --suffix suf - Use suffix suf instead of -gz. Any suffix can be - given, but suffixes other than -z and -gz should be - avoided to avoid confusion when files are transferred - to other. A null suffix forces gunzip to try - decompression on all given files regardless of suffix, - as in: - - gunzip --suffix "" *.* - - Previous versions of gzip used the -z suffix. This was - changed to avoid a conflict with pack on Unix. - - -t --test - Test. Check the compressed file integrity. - - -v --verbose - Verbose. Display the name and percentage reduction for - each file compressed or decompressed. - - -V --version - Version. Display the version number and compilation - options then quit. - - -# --fast --best - Regulate the speed of compression using the specified - digit #, where -1 or --fast indicates the fastest - compression method (less compression) and -9 or --best - indicates the slowest compression method (best compres- - sion). The default compression level is -6 (that is, - biased towards high compression at expense of speed). - -2 ENVIRONMENT - The environment variable GZIP_OPT can hold a set of default - options for gzip. These options are interpreted first and - can be overwritten by explicit command line parameters. For - example: - define GZIP_OPT "-8 -v" - -2 SEE ALSO - compress, zip, unzip - -2 DIAGNOSTICS - Exit status is normally 0; if an error occurs, exit status - is 1. If a warning occurs, exit status is 2. - - Usage: gzip [-cdfhlLnNrtvV19] [-S suffix] [file ...] - Invalid options were specified on the command line. - file: not in gzip format - The file specified to gunzip has not been - compressed. - file: Corrupt input. Use zcat to recover some data. - The compressed file has been damaged. The data up to - the point of failure can be recovered using - define /user sys$output file.recover - zcat file - file: compressed with xx bits, can only handle yy bits - File was compressed (using LZW) by a program that - could deal with more bits than the decompress code - on this machine. Recompress the file with gzip, - which compresses better and uses less memory. - file: already has -gz suffix -- no change - The file is assumed to be already compressed. - Rename the file and try again. - file already exists; do you wish to overwrite (y or n)? - Respond "y" if you want the output file to be - replaced; "n" if not. - gunzip: corrupt input - A SIGSEGV violation was detected which usually means - that the input file has been corrupted. - xx.x% - Percentage of the input saved by compression. - (Relevant only for -v and -l.) - -- not a regular file or directory: ignored - When the input file is not a regular file or direc- - tory, it is left unaltered. - -2 CAVEATS - On VMS: - - upper case options need quotes: gzip "-V". - - restoration of timestamps and version numbers is not supported - - If a compressed file already exists, gzip -f overwrites it, it - does not create a new version. - - multi-part gzip files are not supported. - - gunzip does not preserve the input file format. You can use a - separate utility to restore the original format. - - gunzip and zcat can be used only if you have created the - links to gzip as documented in makegzip.com. Otherwise - you must use explicit parameters ("gzip -c" or "gzip -dc"). - - gzip --list cannot give the uncompressed size and crc. - - When writing compressed data to a tape, it is generally - necessary to pad the output with zeroes up to a block boun- - dary. When the data is read and the whole block is passed to - gunzip for decompression, gunzip detects that there is extra - trailing garbage after the compressed data and emits a warn- - ing by default. You have to use the --quiet option to - suppress the warning. This option can be set in the GZIP_OPT - environment variable as in: - define GZIP_OPT "-q" - -2 BUGS - On VMS, files in VFC record format are not correctly handled by - the C runtime library (the linefeed character is suppressed). - - In some rare cases, the --best option gives worse compres- - sion than the default compression level (-6). On some highly - redundant files, compress compresses better than gzip. diff --git a/Build/source/utils/gzip/vms/makegzip.com b/Build/source/utils/gzip/vms/makegzip.com deleted file mode 100755 index def90f64508..00000000000 --- a/Build/source/utils/gzip/vms/makegzip.com +++ /dev/null @@ -1,71 +0,0 @@ -$!
