forks

Changes for version 0.31

Threads API consistency changes *****
Module CLONE and CLONE_SKIP functions now are passed package name as first argument.
When CLONE_SKIP true in package, all objects in child threads are now cleared. This occurs after fork (unavoidable affect of system fork COW), which hopefully should be portable with all non-perl modules. Note that arrays and hashes will be emptied, but not converted to undef scalar ref; this differs from ithreads (where all become undef scalar ref). Patches are welcome.
Bumped threads $VERSION to 1.72, threads::shared $VERSION to 1.28 to match version-supported features and behavior.
Bug fixes *****
Improve package detection for CLONE and CLONE_SKIP; now identifies all packages in symbol table, not just packages identified by %INC. This allows for support of multiple modules in a file/module that may have CLONE or CLONE_SKIP functions.
Improved Time::HiRes::nanosleep support detection.
Corrected possible race condition with $thr->get_stack_size(). Documented expected behavior.
Miscellaneous changes *****
Added preliminary Perl debugger support. Defaults to tying TTY only to main thread, unless breakpoints exist in user code.
Add some time tolerance in forks08.t, to accomodate for busy systems or slow signal handling.
New CPAN module requirements: Devel::Symdump and Acme::Damn.
Updated to ppport.h 3.16.
