At the turn of the year, and in accordance with the grand schedule of things, occurred a code freeze for perl 5.8.3. Read below for the rest of the discussion that took place on perl5-porters.
Stas Bekman is writing a working demo implementation of the CLONE() function, for people who want to write multithread-friendly XS modules, without overlooking any case. Jan Dubois suggests that h2xs should know about CLONE() and insert the appropriate boilerplates; because currently the amount of code necessary to make an XS implementation of CLONE() work is too big.
Also related to cloning, but more general (as it affects pure-perl code), is bug #24383 : during cloning, hashes with the
:unique attribute weren't made readonly on the interpreter clone. This was fixed by Dave Mitchell.
Marcus Holland-Moritz suspects that the code generated by xsubpp to return arrays and hashes from XS subroutines is potentially leaking memory. As some modules on CPAN appear to work around this, it's already too late to change it -- but this should be documented.
While discussing bug #24767 -- a pack()/unpack() combination that's apparently not idempotent -- Wolfgang Laun asks the question : should unpack() warn when certain unpack codes are applied to an UTF-8 input? This needs further thinking.
Johan Vromans released Getopt::Long 2.34_01, introducing a new experimental feature : options with more than one value.
Dan Kogai released Encode 1.99, a bug-fix release. Tels released Math::Bigint 1.68. Andy Lester released Test::Harness 2.40. Ken Williams released Cwd 2.13.
By doing some benchmarking, Marcus Holland-Moritz reaches the conclusion that using the optimization level
-O3 on Linux with gcc is not worth it. He suggests to default to
Craig Berry posted a status of maintperl on VMS. Several thinks need fixing, including MakeMaker (for which he provided a patch); but maybe Nicholas will decide to release perl 5.8.3 with the same version of MakeMaker that shipped with 5.8.2.
