* Add a new hash key flag HVhek_UNSHARED, to mark all unshared hash keys.Nicholas Clark2006-05-021-2/+4
| | | | | | Otherwise Perl_newSVhek(), called by Perl_hv_iterkeysv(), naively assumes that it can share any hash key directly. p4raw-id: //depot/perl@28069
* Store cop_hints as a shared structure without using any SVs (onNicholas Clark2006-04-121-4/+20
| | | | | ithreads). p4raw-id: //depot/perl@27776
* First stab at using the pad to store the serialised hints data.Nicholas Clark2006-04-111-0/+6
| | | | | | This approach is almost certainly not only wrong, but also doomed. But it's needed to build a correct solution. p4raw-id: //depot/perl@27768
* Need to migrate the refcounted_he structure to be properly shared.Nicholas Clark2006-04-111-5/+32
| | | | | | Add a mutex for manipulated their reference counts. Unwrap the structure, so that for ithreads it can store SVs in pads. p4raw-id: //depot/perl@27764
* Serialise changes to %^H onto the current COP. Return the compile timeNicholas Clark2006-03-311-0/+5
| | | | | | state of %^H as an eleventh value from caller. This allows users to write pragmas. p4raw-id: //depot/perl@27643
* Expunge references to HV_AMAGIC, HV_AMAGICbad and HV_AMAGICmb whichNicholas Clark2006-03-151-13/+0
| | | | | have been unused since revision 1. p4raw-id: //depot/perl@27507
* Move the GvNAME HEK into the IV union - every GV is now 1 pointerNicholas Clark2006-03-051-0/+4
| | | | | smaller. p4raw-id: //depot/perl@27380
* xgv_stash can be stored as a union with the NV, reducing the size ofNicholas Clark2006-02-251-1/+4
| | | | | PVGVs by another pointer. p4raw-id: //depot/perl@27326
* Store the stash for our in the magic slot. This will allow us to useNicholas Clark2006-02-241-2/+8
| | | | | | PVMGs in pad names where previously PVGVs were used. In turn, this gives much greater flexibility for the layout of PVGVs. p4raw-id: //depot/perl@27312

* RMAGIC on symbol tables is bad, m'kay.Nicholas Clark2005-12-301-0/+1
| | | | | | | | Allow hashes (and therefore all symbol tables) to store the backreference array in the hv_aux structure, and thereby undo the performance damage of 24966, which resulted in 60% of all hash lookups trying to mg_find tiehash magic. p4raw-id: //depot/perl@26530

* Store the xhv_aux structure after the main array.Nicholas Clark2005-06-011-11/+12
| | | | | | | This reduces the size of HV bodies from 24 to 20 bytes on a 32 bit build. It has the side effect of defined %symbol_table:: now always being true. defined %hash is already deprecated. p4raw-id: //depot/perl@24660

* Store the package name as a shared HEK.Nicholas Clark2005-05-261-3/+5
| | | | | | | | Abolish HvNAME() - as the stored pointer is not a char* you can't set it directly now. Storing a pointer to a HEK tracks the length too, and seems to be faster. p4raw-id: //depot/perl@24584
