perl-compiler/Changes

-*- change-log -*-
	Started on CPAN with B-C-1.04_12
	The Perl compiler was in CORE from alpha4 until Perl 5.9.4
	and worked quite fine with Perl 5.6 and 5.8

1.37	2012-01-24 rurban
	Enabled copy-on-grow strings >= 5.10.
	Save %main:: stashes w/o -fno-stash. Switched to git, added github mirror
	Fixed hashes and share_hek, when mixed compiled and load-time for >5.8.

	Stability: This release is the first which passes most tests, all
	module tests and is used in production with --staticxs -O3, but
	copy-on-grow hek's and further logical improvements (deferred
	%INC cleanup) fail so far, so it's still considered unstable.

	* C: save stashes optionally with -fstash, but only values which are also
	  stashes to avoid a second walker besides savecv, and thus do not
	  walk into unneeded territory; B::STASHGV (46, issue 79)
	New -fno-stash with -O2 to omit stashes which are rarely needed.
	Fixed vulnerability to oCERT-2011-003 style DOS attacks. Do not
	  pre-compute hashes for hv_store(), use fresh random hash seed.
	  But shared_hek() has a limited API which does not allow this.
	UNIVERSAL methods were not correctly stored, which led to method not
	  found at run-time errors.
	New debug option -Dr "runtime" to add debug output to the .c code (as in CC)
	New option -Upackage to skip package, mark_skip()
	Re-implemented sharepvn via share_hek() and SvLEN=0 (issue 71),
	  Special FAKE+READONLY handling: LEN = 0 if pv_copy_on_grow or shared_hek.
	  Fixed !SvIsCOW_shared_hash + FAKE+READONLY conflict (test 13, issue 82).
	  Shared COW hashkeys which are optimized to static const strings
	  may not be marked as IsCOW (remove SVf_FAKE).
	Re-implemented CORE share_hek with hash=0
	  Otherwise shared HEK's (post-5.10) come up with duplicate entries
	  for the same keys; one compile-time created and one run-time created with
	  a different random hash seed. E.g. observed by such warnings
	  "Prototype mismatch: sub bytes::length (_) vs (_)"
	Added Internals::hv_clear_placeholders XS name exception, similar
	  to version:: (issue 83)
	Store CV prototypes, issue 81 and issue 84 for empty () vs NULL prototypes.
	Fixed 5.15.2 hang at hfree_next_entry (issue 78)
	Defer writing of READONLY hash keys since 5.15 (issue 88)
	Enable -fcog copy-on-grow with static strings for >= 5.10
	Improved Errno vs. *main::! and Tie::Hash::NamedCapture vs
	  *main::+  / - logic (issue 90)
	Updated version XS methods, default to noop for (...
	Strip version object overload from XS packages (issue 91), XS needs plain PVs
	Do not initialize CONSTSUB XS methods twice, boot does it for us
	Pass proper cv to XS boot_$name, fixes boot of
	  Tie::Hash::NamedCapture (issue 86)
	Fixed share_hek strings with -O1 (test 13)
	Fixed bootstrapping the XS/core part of attributes,
	  thereby fixed threads tests 41-43.
	Fixed most 5.8.[45] problems by ignoring aelemfast SPECIAL pads.
	Fixed magic -> PTR when SV (>5.6)
	Moved -fsave-sig-hash from -O3 to -O0. You need -fno-save-sig-hash
	  to disable it.
        Removed -fno-stash from -O2, -fno-stash is now the default. You
	  need -fstash to add stashes. It caused not understood problems.
	Fixed saving %SIG signals and more -2 SV magic (issue 92)
	Adjusted IO logic, was erronously skipped (issue 59)
	inc_cleanup: save only those %INC keys which are stored.
	Save ext/mro only if the ext mro methods were loaded, and
	  utf8_heavy.pl similarly.
	Force loading of -u arguments to avoid runtime loading.
	Call boot_core_PerlIO, mro, UNIVERSAL and xsutils.
	Warn on unsavable IO objects from BEGIN blocks.
	  Fixed >&STD... handles (issue 93),
	  i.e. Test::Builder, Test::NoWarnings and parts of the core testing.
	  See http://blogs.perl.org/users/rurban/2012/01/what-to-avoid-in-begin-blocks.html
	Add B::COP::stashflags workaround, >5.15.4 threaded.
	Add fix for lost PL_regex_pad, 5.15 threaded.
	* CC (1.12): allow overriding of -f<opt> B::C flags.
	Skip internal packages with mark_skip (fixes cc_o2 tests).
	Move -ftype-attr from -O2 to -O1.
	Always define int, double and string package versions, parallel to types.
	* Bytecode (1.12): detect Tie::Hash::NamedCapture (issue 90) -
	  works only partially.
	Fixed >&STD... handles (issue 93)
	Support -d debugging without -MOd
	* Stackobj (1.00_03): add UL or L to overlong integers. doubles
	  not yet
	* perlcc (2.13): added options -O[1-4], -u, -U, --Wc, --Wl, --version,
	Keep cfile if output is empty.
	Change -o output C file directory and name with -S or -c:
	  Before in current directory, now in -o directory.
	  Before with input name, now with -o name.
	Add -rpath for all --staticxs libs if supported.
	Changed verbosity levels and output wording.
	* bytecode.pl: added xio_ifp
	* bytecode.h: added BSET_xio_ifp
	* META.yml: remove from MANIFEST and repo, let make dist
	  autogenerate it.
	* t/test.pl, t/TESTS: changed test 46 (Exporter:: and other stashes in
	  %main:: stash) to cover issue 79.
	  use Exporter; print q(ok) if %main::Exporter::
	* t/test.pl: use general comments with optional TODO. Before only TODO
	* t/perldoc.t: fixed for 5.8 with manually adding -uFile::Spec -uIO::Handle
	* t/issue81.t: added

1.36	2011-10-19 rurban
	lexical warnings and more 5.15 fixes
	* C: new B::LEXWARN, fixed representation of lexical warnings which was broken
	  since 8e01d9a6  5.8.9/5.9.4 (issue 76)
	Added section free, use it for lexical cop_warnings (const STRLEN*)
	  (TODO: static PV, HEK + COPs)
	Workaround for utf8::SWASHNEW adjusted to 5.15
	PAD* sv flags changed in 5.15.3
	XSLoader API changed (HEK in caller i.e.): had to add a
	  XSLoader::load_file for [perl #101336] >= 5.15.3,
	  also use mXPUSH for sp instead of 1-arg targ
	Set SvLEN=0 for static PVs to skip sv_clear (problem with 13)
	Handle overlarge negative 64bit ints, double not yet.
	Move -fwarn-sv from -O2 to -O1
	Move -fsave-data from -O3 to -O2
	Compile *main::DATA IO handle automatically (__DATA__), just package __DATA__
	  handles need -fsave-data (15)
	Die with 5.8.4/5.8.5 threaded with split->pushre on invalid
	  pmreplroot. This is a core B::walkoptree bug and can not be
	  easily fixed.
	Tests 15 and 103 do not hang anymore, 15 and 29 pass mostly
	* C.xs: added -Dts support to runloop to check internal compiler
	  problems
	* t/issue76.t: added

1.35	2011-10-02 rurban
	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

    Fix a couple of compiler-noted nits in #7235.

    Fix of sorts for bug id 20000901.092.  There seems to be no trace
    of a 'pmshort' anywhere in the B, so the offending line was simply
    removed.

    @2452 B.xs had its own code to calculate hash() which differed from

    @2378 More C.pm tweaks
      Save globs even if we have saved cv itself before - may be imported.

      While we don't save "bootstrap" CV we need to provide a stub,
      so that if we require it later we don't fall through and attempt
      to DynaLoad module again.

      Attempt to save %INC so that "require" does not reload things
      we have compiled-in (does not work right yet - seems to be due
      to PL_incgv being created in perl_parse() current scheme setting
      GvHV() is "better" than saving the glob, but still does not
      work as I expect).

Nick Ing-Simmons <nik@tiuk.ti.com>  1998-11-27 22:10:27
    @2332 Handle INIT list in C.pm
    1. Provide init_av() from B.xs
    2. Export it in B.pm
    3. Use it in C.pm
    Also disable some pruning in savecv() which seems to undo
    my previous patch.

    @589 [win32] various cleanups so that B can be built as "just another extension"
     - export symbols needed for building B
     - bset_obj_store() is needed by byterun(), so define it there instead
       of at B.xs, and export it
     - freadpv() is only used in B.xs, so move it there
     - byte*.h are now included by perl.h
     - regenerate embed*.h

Gurusamy Sarathy <gsar@cpan.org>  1998-02-22 02:40:56
    @568 [win32] get compiler building under win32 (needed Makefile.PL

    @585 More compiler tweaks.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 18:23:47
    @565 Remove compiler files from their old lib/B locations. The compiler
    now builds by default (without the byteperl executable so far) and
    seems to work at least minimally.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 18:05:33
    @564 Move lib/B/... and lib/[BO].pm over to where they should be,
    under ext/B.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 17:54:58
    @563 Start getting compiler to work when built with the core.
    [Still won't work as of this change.]

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 16:42:13

	* Merge perlext/Compiler/... into mainline. Some files move to
    ext/B/..., some to lib/B/..., O.pm and B.pm go in lib and some
    move to the base perl directory (e.g. headers). Will need some
    cleaning up before it builds properly, I would guess.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-20 16:39:38
	* [compiler] Win32 changes from Sarathy, tweaked slightly by me.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1998-02-17 17:50:50
	* Assorted changes to the compiler

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-12-10 18:33:53
	Alpha5
	* Start overhauling compiler. It was working at least minimally
    right up until the final tweak of B.xs to add threadsv_names
    at which point building it provokes a seg fault in perl while
    doing the xsubpp :-(.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-09-03 12:31:48
	* Make compiler build/work with devel 5.005

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-07-05 11:58:05
	* Change %lx to %x in B::CV::save to prevent some CV
    fields becoming 0 in the init section. Add missing
    write_back in B::Stackobj::Padsv::load_double to fix
    test 22 of op/my.t.

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-07-05 11:58:05
	* B::CC::pp_padsv must cope with vivify_ref (5.004)
	  as well as provide_ref (5.003)

Malcolm Beattie <mbeattie@sable.ox.ac.uk>  1997-05-03 14:47:06
