You can also now refer to -user-defined character classes from within other user defined character -classes. - -=head1 Modules and Pragmata - -=over 4 - -=item * - -Carp improved to work nicely with Safe. Carp's message reporting should now -be anomaly free - it will always print out line number information. - -=item * - -CGI upgraded to version 3.05 - -=item * - -charnames now avoids clobbering $_ - -=item * - -Digest upgraded to version 1.08 - -=item * - -Encode upgraded to version 2.01 - -=item * - -FileCache upgraded to version 1.04 - -=item * - -libnet upgraded to version 1.19 - -=item * - -Pod::Parser upgraded to version 1.28 - -=item * - -Pod::Perldoc upgraded to version 3.13 - -=item * - -Pod::LaTeX upgraded to version 0.57 - -=item * - -Safe now works properly with Carp - -=item * - -Scalar-List-Utils upgraded to version 1.14 - -=item * - -Shell's documentation has been re-written, and its historical partial -auto-quoting of command arguments can now be disabled. - -=item * - -Test upgraded to version 1.25 - -=item * - -Test::Harness upgraded to version 2.42 - -=item * - -Time::Local upgraded to version 1.10 - -=item * - -Unicode::Collate upgraded to version 0.40 - -=item * - -Unicode::Normalize upgraded to version 0.30 - -=back - -=head1 Utility Changes - -=head2 Perl's debugger - -The debugger can now emulate stepping backwards, by restarting and rerunning -all bar the last command from a saved command history. - -=head2 h2ph - -F<h2ph> is now able to understand a very limited set of C inline functions --- basically, the inline functions that look like CPP macros. This has -been introduced to deal with some of the headers of the newest versions of -the glibc. The standard warning still applies; to quote F<h2ph>'s -documentation, I<you may need to dicker with the files produced>. - -=head1 Installation and Configuration Improvements - -Perl 5.8.5 should build cleanly from source on LynxOS. - -=head1 Selected Bug Fixes - -=over 4 - -=item * - -The in-place sort optimisation introduced in 5.8.4 had a bug. For example, -in code such as - - @a = sort ($b, @a) - -the result would omit the value $b. This is now fixed. - -=item * - -The optimisation for unnecessary assignments introduced in 5.8.4 could give -spurious warnings. This has been fixed. - -=item * - -Perl should now correctly detect and read BOM-marked and (BOMless) UTF-16 -scripts of either endianness. - -=item * - -Creating a new thread when weak references exist was buggy, and would often -cause warnings at interpreter destruction time. The known bug is now fixed. - -=item * - -Several obscure bugs involving manipulating Unicode strings with C<substr> have -been fixed. - -=item * - -Previously if Perl's file globbing function encountered a directory that it -did not have permission to open it would return immediately, leading to -unexpected truncation of the list of results. This has been fixed, to be -consistent with Unix shells' globbing behaviour. - -=item * - -Thread creation time could vary wildly between identical runs. This was caused -by a poor hashing algorithm in the thread cloning routines, which has now -been fixed. - -=item * - -The internals of the ithreads implementation were not checking if OS-level -thread creation had failed. threads->create() now returns C<undef> in if -thread creation fails instead of crashing perl. - -=back - -=head1 New or Changed Diagnostics - -=over 4 - -=item * - -Perl -V has several improvements - -=over 4 - -=item * - -correctly outputs local patch names that contain embedded code snippets -or other characters that used to confuse it. - -=item * - -arguments to -V that look like regexps will give multiple lines of output. - -=item * - -a trailing colon suppresses the linefeed and ';' terminator, allowing -embedding of queries into shell commands. - -=item * - -a leading colon removes the 'name=' part of the response, allowing mapping to -any name. - -=back - -=item * - -When perl fails to find the specified script, it now outputs a second line -suggesting that the user use the C<-S> flag: - - $ perl5.8.5 missing.pl - Can't open perl script "missing.pl": No such file or directory. - Use -S to search $PATH for it. - -=back - -=head1 Changed Internals - -The Unicode character class files used by the regular expression engine are -now built at build time from the supplied Unicode consortium data files, -instead of being shipped prebuilt. This makes the compressed Perl source -tarball about 200K smaller. A side effect is that the layout of files inside -lib/unicore has changed. - -=head1 Known Problems - -The regression test F<t/uni/class.t> is now performing considerably more -tests, and can take several minutes to run even on a fast machine. - -=head1 Platform Specific Problems - -This release is known not to build on Windows 95. - -=head1 Reporting Bugs - -If you find what you think is a bug, you might check the articles -recently posted to the comp.lang.perl.misc newsgroup and the perl -bug database at http://bugs.perl.org. There may also be -information at http://www.perl.org, the Perl Home Page. - -If you believe you have an unreported bug, please run the B<perlbug> -program included with your release. Be sure to trim your bug down -to a tiny but sufficient test case. Your bug report, along with the -output of C<perl -V>, will be sent off to perlbug@perl.org to be -analysed by the Perl porting team.
