* 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

* 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
