* rename PAD_MAX to PERL_PADSEQ_INTRODavid Mitchell2011-02-061-0/+6
| | | | | | | | and increase its scope to all the perl core rather than just pad.c. The scope needs to increase because we'll need to use it in op.c shortly, and the rename is because it's about to lose any significance as a numerical value, and just become a magic number to be tested for equality.
* Store the PL_compcv instead of the the PL_comppad in parser stack, and make ↵Gerard Goossen2009-12-161-1/+2

* Make the style of pad_add_name's flags consistent with pad_new's and pad_tidy's.Nicholas Clark2009-11-151-3/+3

* Convert pad_check_dup() to static linkage, and call it from Perl_pad_add_name().Nicholas Clark2009-11-151-2/+2
| | | | | Provide a flag option to Perl_pad_add_name(), pad_add_NO_DUP_CHECK, to supress the call.
* Refactor common code paths from Perl_pad_add_name() into S_pad_add_name_sv().Nicholas Clark2009-11-151-1/+0
| | | | | | The only user of the pad_add_FAKE flag was S_pad_findlex(), so move the relevant code there from Perl_pad_add_name(), and have S_pad_findlex() call S_pad_add_name_sv() directly. This eliminates the pad_add_FAKE flag completely.
* Add length and flags arguments to Perl_pad_check_dup().Nicholas Clark2009-11-091-0/+11
| | | | | | Currently only pad_add_OUR is used. The length is cross-checked against strlen() on the pointer, but the intent is to re-work the entire pad API to be UTF-8 aware, from the current situation of char * pointers only.
* Use of freed comppad array during clear_yystack()Marcus Holland-Moritz2009-04-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Message-ID: <20081026231720.34258457@r2d2> Patch description from the original email : I tried to make tests pass on a perl built with -DPERL_POISON, as some tests were dying with segfaults. They all originated from the same source: clear_yystack() after a compile error. [...] As far as I can see, after croaking the newly created CV is destroyed and its pad is undef'd. [...] This will SvREFCNT_dec PL_comppad and set PL_comppad to NULL. However, later, in clear_yystack(), when the ops are freed, the old PL_comppad is restored by PAD_RESTORE_LOCAL, as a reference is still in ps->comppad. But now the pad AV is already dead. Normally (i.e. without PERL_POISON), the dead AV will have AvARRAY(av) set to NULL by av_undef(). So PAD_RESTORE_LOCAL will actually set PL_curpad to NULL, and thus pad_free() will not attempt to do anything. But with PERL_POISON, the storage for AvARRAY(av) (i.e. sv_u) will be reused for chaining the free SV heads in the arena (as opposed to SvANY(sv) in case of !PERL_POISON). This means that PAD_RESTORE_LOCAL will find AvARRAY(av) non-NULL and will set PL_curpad to that value, finally causing the segfault in pad_free(). While I think I understand what's going on, I don't have the slightest clue how to properly fix this. Given that it's not a problem only under PERL_POISON, but always (as dead SV heads are being used), I think it should ultimately be fixed. The only thing I can offer right now is a patch to make it work with PERL_POISON as good (or as bad) as without by making PAD_RESTORE_LOCAL explicitly check if the pad passed in is already dead and refusing to use it if it is.
* Add MUTABLE_AV(), and remove (AV *) casts from headers.Nicholas Clark2008-10-271-3/+3
| | | p4raw-id: //depot/perl@34608
* Add a macro MUTABLE_PTR(p), which on (non-pedantic) gcc will not castNicholas Clark2008-10-271-8/+8
| | | | | | | | | | away const, returning a void *. Add MUTABLE_SV(sv) which uses this, and replace all (SV *) casts either with MUTABLE_SV(sv), or (const SV *). This probably still needs some work - assigning to SvPVX() and SvRV() is now likely to generate a casting error. The core doesn't do this. But as-is it's finding bugs that can be fixed. p4raw-id: //depot/perl@34605
