Changes for version 1.35 - 2011-10-02

  • tested from 5.6.2 until 5.15.3
  • C: allow debugging without -MOd=C improve package_pv detection for methods, two more tests. detect previously missing packages within the main sourcefile (50,35,72,73) -O1 now includes also -fav-init2 and -fppaddr, which are all stable. -O2 string handling (-fro-inc) still unstable. added B::REGEXP::save for \$qr (Encode::Alias), issue 71. Still not fully fixed. Encode::Alias unusable. fixed empty HV assertions since 5.15, new HV default keys = 7 (3,4,36), but still unsolved 5.15 problem with endless loop in Perl_hfree_next_entry hv.c:1716 (3,4,36) workaround 5.15.2 inability to walk with from %INC deleted stashes, also workaround adding already deleted DynaLoader. CORE patch [perl #100138] for new 5.15.2-5.15.3 DynaLoader XS_INTERNAL problem required (16,29,44,45). Fixed with 5.15.4 0001-Export-DynaLoader-symbols-from-libperl-again.patch use proper PL_envgv for *main::ENV which is inited in perl_parse (fixes e.g. CGI apps using run-time values, not compile-time)
  • CC (1.11): allow debugging without -MOd=CC Try to jump from last to unknown label, put labels also onto cxstack. Fixed cc_last.t test 4, jump out of anonsub, but not across C functions yet (this is disallowed in C, need to split).
  • C.xs: added B::REGEXP::EXTFLAGS (missing from B).
  • perlcc (2.12): omit also inc_version_list dirs from perlcc as leaving them in could lead to unexpected crashes
  • t/cc_last.t: Fixed test 2. This works compiled and uncompiled, but the returned errcode is not compared. Skip if so.
  • t/TESTS: add all 5 possible method/sub calls to test 35 =>01234. See http://blogs.perl.org/users/rurban/2011/06/how-perl-calls-subs-and-methods.html
  • t/stash.t: fixed 5.8.8 stashes (overload, threads, ...)
  • t/issue71.t: added, but not fixed yet
  • ramblings/*.patches: CORE patches added and recommended in README.
  • ramblings/blogs-debugging-article[1-4].pod: added to MANIFEST.
  • perlcompile.pod, perloptree.pod: improved.
  • ramblings/yapceu_2010.pod: added.
