Scripts which happen to rely on previously -erroneous behaviour will consider these fixes as incompatible changes :-) -You are advised to perform sufficient acceptance testing on this release -to satisfy yourself that this does not affect you, before putting this -release into production. - -The diagnostic output of Carp has been changed slightly, to add a space after -the comma between arguments. This makes it much easier for tools such as -web browsers to wrap it, but might confuse any automatic tools which perform -detailed parsing of Carp output. - -The internal dump output has been improved, so that non-printable characters -such as newline and backspace are output in C<\x> notation, rather than -octal. This might just confuse non-robust tools which parse the output of -modules such as Devel::Peek. - -=head1 Core Enhancements - -=head2 Malloc wrapping - -Perl can now be built to detect attempts to assign pathologically large chunks -of memory. Previously such assignments would suffer from integer wrap-around -during size calculations causing a misallocation, which would crash perl, and -could theoretically be used for "stack smashing" attacks. The wrapping -defaults to enabled on platforms where we know it works (most AIX -configurations, BSDi, Darwin, DEC OSF/1, FreeBSD, HP/UX, GNU Linux, OpenBSD, -Solaris, VMS and most Win32 compilers) and defaults to disabled on other -platforms. - -=head2 Unicode Character Database 4.0.1 - -The copy of the Unicode Character Database included in Perl 5.8 has -been updated to 4.0.1 from 4.0.0. - -=head2 suidperl less insecure - -Paul Szabo has analysed and patched C<suidperl> to remove existing known -insecurities. Currently there are no known holes in C<suidperl>, but previous -experience shows that we cannot be confident that these were the last. You may -no longer invoke the set uid perl directly, so to preserve backwards -compatibility with scripts that invoke #!/usr/bin/suidperl the only set uid -binary is now C<sperl5.8.>I<n> (C<sperl5.8.4> for this release). C<suidperl> -is installed as a hard link to C<perl>; both C<suidperl> and C<perl> will -invoke C<sperl5.8.4> automatically the set uid binary, so this change should -be completely transparent. - -For new projects the core perl team would strongly recommend that you use -dedicated, single purpose security tools such as C<sudo> in preference to -C<suidperl>. - -=head2 format - -In addition to bug fixes, C<format>'s features have been enhanced. See -L<perlform> - -=head1 Modules and Pragmata - -The (mis)use of C</tmp> in core modules and documentation has been tidied up. -Some modules available both within the perl core and independently from CPAN -("dual-life modules") have not yet had these changes applied; the changes -will be integrated into future stable perl releases as the modules are -updated on CPAN. - -=head2 Updated modules - -=over 4 - -=item Attribute::Handlers - -=item B - -=item Benchmark - -=item CGI - -=item Carp - -=item Cwd - -=item Exporter - -=item File::Find - -=item IO - -=item IPC::Open3 - -=item Local::Maketext - -=item Math::BigFloat - -=item Math::BigInt - -=item Math::BigRat - -=item MIME::Base64 - -=item ODBM_File - -=item POSIX - -=item Shell - -=item Socket - -There is experimental support for Linux abstract Unix domain sockets. - -=item Storable - -=item Switch - -Synced with its CPAN version 2.10 - -=item Sys::Syslog - -C<syslog()> can now use numeric constants for facility names and priorities, -in addition to strings. - -=item Term::ANSIColor - -=item Time::HiRes - -=item Unicode::UCD - -=item Win32 - -Win32.pm/Win32.xs has moved from the libwin32 module to core Perl - -=item base - -=item open - -=item threads - -Detached threads are now also supported on Windows. - -=item utf8 - -=back - -=head1 Performance Enhancements - -=over 4 - -=item * - -Accelerated Unicode case mappings (C</i>, C<lc>, C<uc>, etc). - -=item * - -In place sort optimised (eg C<@a = sort @a>) - -=item * - -Unnecessary assignment optimised away in - - my $s = undef; - my @a = (); - my %h = (); - -=item * - -Optimised C<map> in scalar context - -=back - -=head1 Utility Changes - -The Perl debugger (F<lib/perl5db.pl>) can now save all debugger commands for -sourcing later, and can display the parent inheritance tree of a given class. - -=head1 Installation and Configuration Improvements - -The build process on both VMS and Windows has had several minor improvements -made. On Windows Borland's C compiler can now compile perl with PerlIO and/or -USE_LARGE_FILES enabled. - -C<perl.exe> on Windows now has a "Camel" logo icon. The use of a camel with -the topic of Perl is a trademark of O'Reilly and Associates Inc., and is used -with their permission (ie distribution of the source, compiling a Windows -executable from it, and using that executable locally). Use of the supplied -camel for anything other than a perl executable's icon is specifically not -covered, and anyone wishing to redistribute perl binaries I<with> the icon -should check directly with O'Reilly beforehand. - -Perl should build cleanly on Stratus VOS once more. - -=head1 Selected Bug Fixes - -More utf8 bugs fixed, notably in how C<chomp>, C<chop>, C<send>, and -C<syswrite> and interact with utf8 data. Concatenation now works correctly -when C<use bytes;> is in scope. - -Pragmata are now correctly propagated into (?{...}) constructions in regexps. -Code such as - - my $x = qr{ ... (??{ $x }) ... }; - -will now (correctly) fail under use strict. (As the inner C<$x> is and -has always referred to C<$::x>) - -The "const in void context" warning has been suppressed for a constant in an -optimised-away boolean expression such as C<5 || print;> - -C<perl -i> could C<fchmod(stdin)> by mistake. This is serious if stdin is -attached to a terminal, and perl is running as root. Now fixed. - -=head1 New or Changed Diagnostics - -C<Carp> and the internal diagnostic routines used by C<Devel::Peek> have been -made clearer, as described in L</Incompatible Changes> - -=head1 Changed Internals - -Some bugs have been fixed in the hash internals. Restricted hashes and -their place holders are now allocated and deleted at slightly different times, -but this should not be visible to user code. - -=head1 Future Directions - -Code freeze for the next maintenance release (5.8.5) will be on 30th June -2004, with release by mid July. - -=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.
