Changes for version 1.46 - 2014-05-14

  • Added global destruction, improved -O4 and CC, fixed mro, @-, $/ $\, Net::DNS, ... Added mro and re core testsuite.
  • C: reset PL_stack_sp on init (was one too far). no effects on code. Implement global destruction via sv_clean_objs and my_curse on -O3, resp. prepend static svs PL_sv_arenaroot for sv_clean_objs with a fake sv_list[0]. (#197, #208, #254, #280) Call DESTROY methods for all our global static SVs (i.e. "global destruction"), fixes #197, #280, #282 Increment GV->FORM refcounts as they cannot be destructed, analog to CV Call PL_exitlist functions with -O3 Make the lexical cop_warnings pointer dynamic, because on cv_undef (scope exit, assign, exit, die, ...) CvROOT and all its kids are freed, ignoring op_latefreed. The content of the warning is still a static string - and leaks on perl, but we don't care. -fwarn-sv is now always set, just not with MSVC on Windows. The warnings are then directly set, not in a tight loop afterwards, because the value is needed for the dynamic init. Fixed lexical warnings on 5.8 (pWARN_STD .. pWARN_NONE) Improve -O4 by keeping all CvSTART cops Keep internal packages if used in the source code, e.g. mro (#300) Fix the order of PerlIO_cleanup, after global destruction (#302, #303) Since 5.18 padlists are now all dynamic, due to undef issues in non-local exits (#304) Add -fno-dyn-padlist to -O4 to keep static padlists on 5.18. Dynamic padlists are needed to prevent from cv_undef crashes on static padlists when cleaning up the stack on non-local exits, like die or exit or subs on the compile stack as with Attribute::Handler (#169, #304). Previously only END block function padlists were dynamic (#298). Add run-time remap of compile-time XS symbols via dlsym (#305, RT #94069) Net::DNS includes Encode::XS ascii_encoding, but also init the 3 other encoding ptrs. Add a fast path for d_dlopen + i_dlfcn systems (i.e. Windows goes the slow init2 route) Detect new Encode-2.58 which stores encodings better to handle proper compile-time usage (#305, RT #94221) Add special SV associations for $/, $@ and $\ (#306, #256) Save @ISA for all included packages, esp. DynaLoader dependencies (#308) Replace each %hash with foreach sort keys (#307) Set ${^GLOBAL_PHASE} with -O3 for END and DESTRUCT (#197, #208) Do not store invalid GvCV symbols, only cv or &sv_list entries (#313) Support GvFORM pseudo CVs (B::FM objects) on 5.10 (#149) Support local $/ = "somestring" (only used empty values before) (#314), A regression from 1.43 Support local $\ = "somestring" (#318), also a regression from 1.43 Fix special 5.6. associations for $, $\ as they are no SVs there (#306) Fix wrong caching of internal LEXWARN symbols (#322) Warn on bad IO::Socket::SSL versions 1.956-1.983 which would SEGV if used as server (#317) Support __DATA__ blocks in packages without printing wrong warnings (#310) Support ->(maybe|next)::(method|can) mro method calls (#324, #301) Support mro c3 (#316) Support @- @LAST_MATCH_START, the array of the last submatches (#281, #220, #295) Workaround a 5.18 de-optimization which disabled ++PL_sv_objcount on bless by adding it if a DESTROY method exists. This will fail since 5.18 if DESTROY is added at run-time. (#208, #197) Add new init0 section to initialize -fppaddr ops before init, not afterwards. (#330) Needed to call utf8::SWASHINIT at init with CALLREGCOMP and /i Avoid duplicate PL_utf8_tofold ToCf swash initialization with 5.18 (#330)
  • CC (1.15): Skip saving non-existing methods analog to B::C 1.43_06 (CC test 50) Fix failing CopFILE_free and CopSTASH_free in END blocks with threads (#296, CC test 48) Handle duplicate function names, like multiple END blocks or anon functions (#297) Replace each %hash with foreach sort keys (#307)
  • Bytecode (1.15): Replace each %hash with foreach keys (#307)
  • Bblock (1.04): Do not pollute B::CC (find_leaders) with B::Concise
