* Allow lvalue usage of SvRV() and add MUTABLE_SV() check.Marcus Holland-Moritz2008-11-101-1/+13
| | | | | Also add new SvRV_const() macro for read-only access. p4raw-id: //depot/perl@34804
* Revert SvPVX() to allow lvalue usage, but also add aMarcus Holland-Moritz2008-11-071-1/+1
| | | | | | | MUTABLE_SV() check. Use SvPVX_const() instead of SvPVX() where only a const SV* is available. Also fix two falsely consted pointers in Perl_sv_2pv_flags(). p4raw-id: //depot/perl@34770
* Correct SvVALID() and SvTAIL() - they are actually const.Nicholas Clark2008-10-271-2/+2
| | | p4raw-id: //depot/perl@34613
* Add a macro MUTABLE_PTR(p), which on (non-pedantic) gcc will not castNicholas Clark2008-10-271-41/+41
| | | | | | | | | | 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

| | | | | | | | | #if defined(__GNUC__) && !defined(__STRICT_ANSI__) && !defined(PERL_GCC_PEDANTIC) to #if defined(__GNUC__) && !defined(PERL_GCC_BRACE_GROUPS_FORBIDDEN) because the ({}) construction can be used under __STRICT_ANSI__ (and should be, because it avoids temporary use of PL_Sv). p4raw-id: //depot/perl@33077

* For 5.12: saner behaviour for `length`Nicholas Clark2008-01-121-0/+2

* BER is all very well, but it turns out that it's better to store theNicholas Clark2008-01-051-6/+63
| | | | | | | | offset as either a byte (if <256), or a 0 byte with a STRLEN before. "better" in that the reading can be inlined, and even then the object code is smaller (function calls have space overhead). So goodbye Perl_sv_read_offset() and hello SvOOK_offset(). p4raw-id: //depot/perl@32838
* Re-implement the SvOOK() hack to store the offset as a BER encodedNicholas Clark2008-01-041-5/+12
| | | | | | | | | | | number in the part of the PVX that is being released. (It will always fit, as chopping off 1 byte gives just enough space for recording a delta of up to 127). This allows SvOOK() to co-exist with SvIOK_on(), which means all the calls to SvOOK_off() [with the possibility of a call to sv_backoff()] in SvIOK_on() can be removed. This ought to make a lot of straight line code a little bit simpler. OOK()d scalars can now be SVt_PV, as the IVX isn't needed. p4raw-id: //depot/perl@32836

* Add a new function newSVpvn_flags(), which takes a third parameter ofNicholas Clark2008-01-021-0/+11
| | | | | | | | | | flag bits. Right now the only flag bit is SVf_UTF8, which will call SvUTF8_on() on the new SV for you. Provide a wrapper newSVpvn_utf8(), which takes a boolean, and passes in SVf_UTF8 if that is true. Refactor the core to use it where possible. It makes the source code clearer and smaller, but seems to be swings and roundabouts on object code size. p4raw-id: //depot/perl@32807

* Also get copy on write working with ithreads. It hadn't been workingNicholas Clark2007-06-241-1/+3

* Where possible, use SvIV instead of SvIVX, SvNV instead of SvNVX,Nicholas Clark2007-04-211-7/+11
| | | | | | | | | SvUV instead of SvUVX, and SvPV* variants instead of SvPVX*. Document that the non-x variants are preferable whenever the expression has no side effects.

* Change the API doc for some of the SvXXX testing macros.Rafael Garcia-Suarez2007-01-081-24/+24

Make SvOK() check the flags of the referenant for a BIND, as I envisage that the only flag bit that will get set on a BIND is SVf_UTF8 even if the referant has a defined value. p4raw-id: //depot/perl@29642
