Weak reference deletion remains I<O(n)>, but if deletion only -happens at program exit, it may be skipped completely. - -=item * - -Salvador Fandiņo provided improvements to reduce the memory usage of C<sort> -and to speed up some cases. - -=item * - -Jarkko Hietaniemi and Andy Lester worked to mark as much data as possible in -the C source files as C<static>, to increase the proportion of the executable -file that the operating system can share between process, and thus reduce -real memory usage on multi-user systems. - -=back - -=head1 Installation and Configuration Improvements - -Parallel makes should work properly now, although there may still be problems -if C<make test> is instructed to run in parallel. - -Building with Borland's compilers on Win32 should work more smoothly. In -particular Steve Hay has worked to side step many warnings emitted by their -compilers and at least one C compiler internal error. - -C<Configure> will now detect C<clearenv> and C<unsetenv>, thanks to a patch -from Alan Burlison. It will also probe for C<futimes> and whether C<sprintf> -correctly returns the length of the formatted string, which will both be used -in perl 5.8.9. - -There are improved hints for next-3.0, vmesa, IX, Darwin, Solaris, Linux, -DEC/OSF, HP-UX and MPE/iX - -Perl extensions on Windows now can be statically built into the Perl DLL, -thanks to a work by Vadim Konovalov. (This improvement was actually in 5.8.7, -but was accidentally omitted from L<perl587delta>). - -=head1 Selected Bug Fixes - -=head2 no warnings 'category' works correctly with -w - -Previously when running with warnings enabled globally via C<-w>, selective -disabling of specific warning categories would actually turn off all warnings. -This is now fixed; now C<no warnings 'io';> will only turn off warnings in the -C<io> class. Previously it would erroneously turn off all warnings. - -This bug fix may cause some programs to start correctly issuing warnings. - -=head2 Remove over-optimisation - -Perl 5.8.4 introduced a change so that assignments of C<undef> to a -scalar, or of an empty list to an array or a hash, were optimised away. As -this could cause problems when C<goto> jumps were involved, this change -has been backed out. - -=head2 sprintf() fixes - -Using the sprintf() function with some formats could lead to a buffer -overflow in some specific cases. This has been fixed, along with several -other bugs, notably in bounds checking. - -In related fixes, it was possible for badly written code that did not follow -the documentation of C<Sys::Syslog> to have formatting vulnerabilities. -C<Sys::Syslog> has been changed to protect people from poor quality third -party code. - -=head2 Debugger and Unicode slowdown - -It had been reported that running under perl's debugger when processing -Unicode data could cause unexpectedly large slowdowns. The most likely cause -of this was identified and fixed by Nicholas Clark. - -=head2 Smaller fixes - -=over 4 - -=item * - -C<FindBin> now works better with directories where access rights are more -restrictive than usual. - -=item * - -Several memory leaks in ithreads were closed. An improved implementation of -C<threads::shared> is available on CPAN - this will be merged into 5.8.9 if -it proves stable. - -=item * - -Trailing spaces are now trimmed from C<$!> and C<$^E>. - -=item * - -Operations that require perl to read a process' list of groups, such as reads -of C<$(> and C<$)>, now dynamically allocate memory rather than using a -fixed sized array. The fixed size array could cause C stack exhaustion on -systems configured to use large numbers of groups. - -=item * - -C<PerlIO::scalar> now works better with non-default C<$/> settings. - -=item * - -You can now use the C<x> operator to repeat a C<qw//> list. This used -to raise a syntax error. - -=item * - -The debugger now traces correctly execution in eval("")uated code that -contains #line directives. - -=item * - -The value of the C<open> pragma is no longer ignored for three-argument -opens. - -=item * - -The optimisation of C<for (reverse @a)> introduced in perl 5.8.6 could -misbehave when the array had undefined elements and was used in LVALUE -context. Dave Mitchell provided a fix. - -=item * - -Some case insensitive matches between UTF-8 encoded data and 8 bit regexps, -and vice versa, could give malformed character warnings. These have been -fixed by Dave Mitchell and Yves Orton. - -=item * - -C<lcfirst> and C<ucfirst> could corrupt the string for certain cases where -the length UTF-8 encoding of the string in lower case, upper case or title -case differed. This was fixed by Nicholas Clark. - -=item * - -Perl will now use the C library calls C<unsetenv> and C<clearenv> if present -to delete keys from C<%ENV> and delete C<%ENV> entirely, thanks to a patch -from Alan Burlison. - -=back - -=head1 New or Changed Diagnostics - -=head2 Attempt to set length of freed array - -This is a new warning, produced in situations such as this: - - $r = do {my @a; \$#a}; - $$r = 503; - -=head2 Non-string passed as bitmask - -This is a new warning, produced when number has been passed as a argument to -select(), instead of a bitmask. - - # Wrong, will now warn - $rin = fileno(STDIN); - ($nfound,$timeleft) = select($rout=$rin, undef, undef, $timeout); - - # Should be - $rin = ''; - vec($rin,fileno(STDIN),1) = 1; - ($nfound,$timeleft) = select($rout=$rin, undef, undef, $timeout); - -=head2 Search pattern not terminated or ternary operator parsed as search pattern - -This syntax error indicates that the lexer couldn't find the final -delimiter of a C<?PATTERN?> construct. Mentioning the ternary operator in -this error message makes it easier to diagnose syntax errors. - -=head1 Changed Internals - -There has been a fair amount of refactoring of the C<C> source code, partly to -make it tidier and more maintainable. The resulting object code and the -C<perl> binary may well be smaller than 5.8.7, in particular due to a change -contributed by Dave Mitchell which reworked the warnings code to be -significantly smaller. Apart from being smaller and possibly faster, there -should be no user-detectable changes. - -Andy Lester supplied many improvements to determine which function -parameters and local variables could actually be declared C<const> to the C -compiler. Steve Peters provided new C<*_set> macros and reworked the core to -use these rather than assigning to macros in LVALUE context. - -Dave Mitchell improved the lexer debugging output under C<-DT> - -Nicholas Clark changed the string buffer allocation so that it is now rounded -up to the next multiple of 4 (or 8 on platforms with 64 bit pointers). This -should reduce the number of calls to C<realloc> without actually using any -extra memory. - -The C<HV>'s array of C<HE*>s is now allocated at the correct (minimal) size, -thanks to another change by Nicholas Clark. Compile with -C<-DPERL_USE_LARGE_HV_ALLOC> to use the old, sloppier, default. - -For XS or embedding debugging purposes, if perl is compiled with -C<-DDEBUG_LEAKING_SCALARS_FORK_DUMP> in addition to -C<-DDEBUG_LEAKING_SCALARS> then a child process is C<fork>ed just before -global destruction, which is used to display the values of any scalars -found to have leaked at the end of global destruction. Without this, the -scalars have already been freed sufficiently at the point of detection that -it is impossible to produce any meaningful dump of their contents. This -feature was implemented by the indefatigable Nicholas Clark, based on an idea -by Mike Giroux. - -=head1 Platform Specific Problems - -The optimiser on HP-UX 11.23 (Itanium 2) is currently partly disabled (scaled -down to +O1) when using HP C-ANSI-C; the cause of problems at higher -optimisation levels is still unclear. - -There are a handful of remaining test failures on VMS, mostly due to -test fixes and minor module tweaks with too many dependencies to -integrate into this release from the development stream, where they have -all been corrected.
