* Simplify embedvar.h, removing a level of macro indirection for PL_* variables.Nicholas Clark2011-08-111-33/+35
| | | | | | | For the default (non-multiplicity) configuration, PERLVAR*() macros now directly expand their arguments to tokens such as C<PL_defgv>, instead of expanding to C<PL_Idefgv>. This removes over 350 lines from F<embedvar.h>, which defined macros to map from C<PL_Idefgv> to C<PL_defgv> and so forth.
* Re-order perlvars.h to group related variables, and spread mutexes out.Nicholas Clark2011-06-121-45/+41
| | | | | | Move variables smaller than pointers into groups, to avoid holes in the structure for PERL_GLOBAL_STRUCT. Spreading the mutexes out tries to keep them off the same cache lines, which may help slightly on multi-processor machines.
* PL_perlio_mutex is only needed with USE_UIHREADS && USE_PERLIONicholas Clark2011-06-121-1/+1
| | | | (Not that Configure will let you configure with ithreads but without perlio)
* Change PL_use_safe_putenv from int to bool.Nicholas Clark2011-06-121-1/+1
| | | | | It is only ever checked for truth/falsehood, and all assignments to it (in core and on CPAN) are either 0 or 1.
* Move PL_runops_{std,dbg} to perl.h, and make them const.Nicholas Clark2011-06-121-6/+0
| | | | | They exist solely to ensure that Perl_runops_standard and Perl_runops_debug are linked in - nothing assigns to either variable, and nothing reads them.
* Move PL_global_struct_size, PL_interp_size{,_5_16_0} to perl.hNicholas Clark2011-06-121-18/+0
| | | | Make them const U16 - they should have been const from the start.
* In perlvar.h, move the always-present globals above those conditionally compiledNicholas Clark2011-06-121-2/+2
| | | | | Rename PL_interp_size_5_10_0 to PL_interp_size_5_16_0, as it is only intended to track interpreter size within (forwards) binary compatible maintenance branches.
* Move PL_{revision,version,subversion} to perl.h, making them const U8.Nicholas Clark2011-06-121-9/+0
| | | | | To get the initialisation to work, the location of #include patchlevel.h needs to be moved.
* Move PL_sh_path to perl.h (except for OS/2), as it's const char[]Nicholas Clark2011-06-121-5/+1
| | | | | | | | On OS/2, keep it in perlvars.h, as it's not const there. makedef.pl doesn't pay attention to C pre-processor symbols, so it will always see the declaration in perlvars.h, and add the symbol to the linker file, so no need to mention sh_path in globvar.sym. Add special case logic in regen/embed.pl to make the embedvar.h macros for PL_sh_path defined only on OS/2.
* Move PL_{No,Yes,hexdigit} from perlvars.h to perl.h, as all are const char[]Nicholas Clark2011-06-121-6/+0
| | | | | | | | | | | They were converted in perl.h from const char[] to #define in 31fb120917c4f65d, then re-instated as const char[], but in perlvars.h, in 3fe35a814d0a98f4. There's no need for compile-time constants to jump through the hoops of perlvars.h, even for Symbian, as the various "EXTCONST" variables already in perl.h demonstrate. These were the only 3 users of the the PERLVARISC macro, so eliminate that, and all related code.
* Eliminate PL_patleave, unused since perl 5.0 alpha 2.Nicholas Clark2011-06-121-1/+0
| | | | | | | patleave was added in perl 3.0 patch #35 patch #29 -- 395c379347344a50, used in scanpat(). scanpat() was refactored and renamed to scan_pat() in 5.0 alpha 2, "commented" out with the C pre-processor in 5.000, and removed in 5.001.
* Restore building with -DPERL_GLOBAL_STRUCT, broken since 4dc941f7cb795735.Nicholas Clark2011-05-221-1/+0
| | | | | | | | | As PL_charclass is a constant, it doesn't need to be accessed via the global struct. It should be exported via globvar.sym, not PERLVARA() in perlvars.h [With a PERVARA() it all compiles perfectly, once C<dVAR>s are added where now needed, but the build loops forever because the (real) charclass array is never initialised]
* RT #76248: double-freed SV with nested sig-handlerDavid Mitchell2010-11-011-4/+0
| | | | | | | | | | | | | | | | | | | There was some buggy code in Perl_sighandler() related to getting an SV with the signal name to pass to the perl-level handler function. ` Basically: on threaded builds, a sig handler that died leaked PL_psig_name[sig]; on unthreaded builds, in a recursive handler that died, PL_sig_sv was prematurely freed. PL_sig_sv was originally just a file static var that was not recursion-save anyway, and got promoted to perlvars.h when it should instead have been done away with. So I've got rid of it now, and rationalised the code, which fixed the two issues listed above. Also added an assert which makes the dodgy manual popping of the save stack slightly less dodgy.

* lexer APIZefram2009-11-151-8/+1
| | | | | | | | | Attached is a patch that adds a public API for the lowest layers of lexing. This is meant to provide a solid foundation for the parsing that Devel::Declare and similar modules do, and it complements the pluggable keyword mechanism. The API consists of some existing variables combined with some new functions, all marked as experimental (which making them public certainly is).
* Implement facility to plug in syntax triggered by keywordsJesse Vincent2009-11-051-3/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Date: Tue, 27 Oct 2009 01:29:40 +0000 From: Zefram <zefram@fysh.org> To: perl5-porters@perl.org Subject: bareword sub lookups Attached is a patch that changes how the tokeniser looks up subroutines, when they're referenced by a bareword, for prototype and const-sub purposes. Formerly, it has looked up bareword subs directly in the package, which is contrary to the way the generated op tree looks up the sub, via an rv2cv op. The patch makes the tokeniser generate the rv2cv op earlier, and dig around in that. The motivation for this is to allow modules to hook the rv2cv op creation, to affect the name->subroutine lookup process. Currently, such hooking affects op execution as intended, but everything goes wrong with a bareword ref where the tokeniser looks at some unrelated CV, or a blank space, in the package. With the patch in place, an rv2cv hook correctly affects the tokeniser and therefore the prototype-based aspects of parsing. The patch also changes ck_subr (which applies the argument context and checking parts of prototype behaviour) to handle subs referenced by an RV const op inside the rv2cv, where formerly it would only handle a gv op inside the rv2cv. This is to support the most likely kind of modified rv2cv op. [This commit includes the Makefile.PL for XS-APITest-KeywordRPN missing from the original patch, as well as updates to perldiag.pod and a MANIFEST sort]

Additionally under MULTIPLICITY record the size of the interpreter structure (total, and for this version) and under PERL_GLOBAL_STRUCT the size of the global variables structure. Coupled with PL_bincompat_options this will allow 5.10.1 (and later), when compiled with a shared perl library, to perform sanity checks in main() to verify that the shared library is indeed binary compatible. p4raw-id: //depot/perl@32238
