* plugin mechanism to rewrite calls to a subroutineZefram2010-10-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | New magic type PERL_MAGIC_checkcall attaches a function to a CV, which will be called as the second half of the op checker for an entersub op calling that CV. Default state, in the absence of this magic, is to process the CV's prototype if it has one, or apply list context to all the arguments if not. New API functions cv_get_call_checker() and cv_set_call_checker() provide a clean interface to this facility, hiding the internal use of magic. Expose in the API the new functions rv2cv_op_cv(), ck_entersub_args_list(), ck_entersub_args_proto(), and ck_entersub_args_proto_or_list(), which are meaningful segments of standard entersub op checking and are likely to be useful in plugged-in call checker functions. Expose new API function op_contextualize(), which is a public interface to the internal scalar()/list()/scalarvoid() functions. This API is likely to be required in most plugged-in call checker functions. Incidentally add new function mg_free_type(), in the API, which will remove magic of one type from an SV. (mg_free() removes all magic, and there isn't anything else more selective.)

* MY_CXT macros: make the two sets of defs similarDavid Mitchell2010-09-011-8/+12
| | | | | | | Three years ago there was a cut and paste of all the MY_CXT macros into a second #ifdef PERL_GLOBAL_STRUCT_PRIVATE branch with minor modifications (Bad programmer! No cookie!). Make the two branches more similar in preparation for a partial merge. No functional changes.
* Remove CALL_FPTR and CPERLscope.Ben Morrow2010-08-201-40/+47
| | | | | | | | | | | | | | | | These are left from PERL_OBJECT, which was an implementation of multiplicity using C++ objects. PERL_OBJECT was removed in 5.8, but the macros seem to have been cargo-culted all over the core (including in places where they would have been inappropriate originally). Since they now do exactly nothing, it's cleaner to remove them. I have left the definitions in perl.h, under #ifndef PERL_CORE, since some CPAN XS code uses them (also often incorrectly). I have also left STATIC alone, since it seems potentially more useful and is much more ingrained. The only appearance of these macros this patch doesn't touch is in Devel-PPPort, because that's a CPAN module.
* Revert "Make the peep recurse via PL_peepp"Florian Ragwitz2010-08-161-7/+1
| | | | | | | | | | | | | This reverts commit 65bfe90c4b4ea5706a50067179e60d4e8de6807a. While it made a few of the things I wanted possible, a couple of other things one might need to do and I thought this change would enable don't actually work. Thanks Zefram for pointing out my mistake. Conflicts: ext/XS-APItest/APItest.xs op.c
* make string-append on win32 100 times fasterWolfram Humann2010-08-131-0/+8
| | | | | | | | | | | | | | | | When a string grows (e.g. gets appended to), perl calls sv_grow. When sv_grow decides that the memory currently allocated to the string is insufficient, it calls saferealloc. Depending on whether or not perl was compiled with 'usemymalloc' this calls realloc in either perls internal version or on the operating system. Perl requests from realloc just the amount of memory required for the current operation. With 'usemymalloc' this is not a problem because it rounds up memory allocation to a certain geometric progression anyway. When the operating system's realloc is called, this may or may not lead to desaster, depending on how it's implemented. On win32 it does lead to desaster: when I loop 1000 times and each time append 1000 chars to an initial string size of 10 million, the memory grows from 10.000e6 to 10.001e6 to 10.002e6 and so on 1000 times till it ends at 11.000e6.
* Check API compatibility when loading xs modulesFlorian Ragwitz2010-07-261-0/+4
| | | | | | | | | | | | | This adds PL_apiversion, allowing the API version of a running interpreter to be introspected. It is used in the new XS_APIVERSION_BOOTCHECK macro, which is added to the _boot function of every XS module, to compare it against the API version the module has been compiled against. If the versions do not match, an exception is thrown. This doesn't fully prevent binary incompatible extensions to be loaded. It merely compares PERL_API_* between compile- and runtime, and does not attempt to solve the problem of identifying binary incompatible perls with the same API version (i.e. the same perl version configured with and without DEBUGGING).
* Make the peep recurse via PL_peeppFlorian Ragwitz2010-07-251-1/+7
| | | | | | | | | | | Also allows extensions, when delegating to Perl_peep, to specify what function it should use when recursing into a part of the op tree. The usecase for this are extensions like namespace::alias, which need to hook into the peep to do their thing. With this change they can stop copying the whole peep only to add tiny bits of new behaviour to it, allowing them to work easier on a large variety of perls, without having to maintain one peep which works on all of them (which is HARD!).
* Add a Configure probe for static inline.Andy Dougherty2010-07-221-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | This patch enables Configure to probe for C99-style 'static inline'. (That is, functions may be inlined, but will not be externally visible.) The initial idea is that some common code in messy macros inside headers might be simplified using inline functions. If the compiler does not support 'static inline', then a plain 'static' is used instead, along with the consequent implications of a function call (though the compiler may optimize away the function call and inline the function anyway). In either case, you simply use PERL_STATIC_INLINE. This patch does not *use* this facility at all yet. It is merely a Configure patch to make the facility availble for others to experiment with. VMS and Windows files will still need to be manually updated. Finally, before actually converting anything to inline functions, please try to carefully evaluate the performance implications of any proposed changes. Compilers vary in what they will and will not convert to inline functions, so it's worth proceeding slowly and carefully. This patch results from a single new metaconfig unit, d_static_inline.U, which I will separately upload to the metaconfig repository.
* Macroify the block_hooks structure.Ben Morrow2010-07-121-0/+2
| | | | | Add a flags member, so it can be extended later if necessary. Add a bhk_eval member, called from doeval to catch requires and string evals.
* add my_[l]stat_flags(); make my_[l]stat() mathomsDavid Mitchell2010-07-031-0/+4
| | | | | | | my_stat() and my_lstat() call get magic on the stack arg, so create _flags() variants that allow us to control this. (I can't just change the signature or the mg_get() behaviour since my_[l]stat() are listed as being in the public API, even though they're undocumented.)

* Introduce C<use feature "unicode_strings">Rafael Garcia-Suarez2009-12-201-1/+1
| | | | | | | | | | | | | This turns on the unicode semantics for uc/lc/ucfirst/lcfirst operations on strings without the UTF8 bit set but with ASCII characters higher than 127. This replaces the "legacy" pragma experiment. Note that currently this feature sets both a bit in $^H and a (unused) key in %^H. The bit in $^H could be replaced by a flag on the uc/lc/etc op. It's probably not feasible to test a key in %^H in pp_uc in friends each time we want to know which semantics to apply.

* Inline PL_no_symref_sv into its users. Deprecate the visible global variable.Nicholas Clark2009-11-151-2/+4
| | | | | | | | | As the core no longer needs this fixed string outside of pp.c, it seems daft to make it public just in case any module wants to use it. Modules that do should provide their own inline copy in future. Also restore the visible global PL_no_symref_sv back to the original format specificiation (of 5.10.0 and earlier).
* Inline PL_no_symref into pp_entersub. Deprecate the visible global variable.Nicholas Clark2009-11-151-2/+2
| | | | | | | | | | | As the core no longer needs this fixed string in more than one place, it seems daft to go to the overhead (and cost) of making it public in case any module wants to use it. Modules that do want to use it should provide their own inline copy in future. Also restore the visible global PL_no_symref back to the original format specification (of 5.10.0 and earlier), as an extra %s has the potential to cause SEGVs or worse if not spotted at compile time.

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]

* | Remove binary compatibility scaffolding for the change to PL_bitcount.Nicholas Clark2009-05-201-15/+0
| |
* | Replace run-time on-demand initialisation of PL_bitcount with a constant table.Nicholas Clark2009-05-201-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (The table is 256 bytes; the run-time initialisation code is larger than this!) Adapt generate_uudmap.c to generate the initalisation block for PL_bitcount, writing the code to bitcount.h, using the same approach as uudmap.h. To preserve binary compatibility: for MULTIPLICITY: keep Ibitcount in the interpreter structure, but remove all the macros that access it. PL_bitcount is a new symbol in the object file, which won't clash with anything as that name wasn't used before. otherwise: keep PL_bitcount as a char *, but initialise it at compile time to a new constant array PL_bitcount array. Remove the code that attempts to Safefree() it at interpreter destruction time.

| | | | | | | | | | | | | | | | (MacOS support was removed from MakeMaker in 6.22, and merged to blead on 15th December 2004 with 5dca256ec738057dc331fb644a93eca44ad5fa14. After this point MacOS wouldn't even have been able to build the perl binary, because it would not have been able to build DynaLoader. If anyone wishes to resurrect MacOS, start by reversing this commit and the relevant part of that commit.)

* VMS posix exit fixesJohn Malmberg2009-01-041-27/+28
| | | | | | | | | | | | | | | | | | | | | | | perl.h and perl.c need further fixes to get VMS to return the expected POSIX exit codes when that is enabled. This fix gets the correct numbers except for the SIGTERM case, which will need some more work. It also gets the posix exit code to set an error severity on a fatal exit so that DCL and MMS/MMK or VMS native programs can easily detect a script failure. This patch does not address an issue in vms.c where the feature logicals may not be correctly read. That will follow in a future patch. The tests have been adjusted to detect when VMS is in the POSIX exit mode and perform properly. -John wb8tyw@gmail.com -- My qsl.net e-mail address is temporarily out of order.
