* Add Perl_ck_warner_d(), which combines Perl_ckwarn_d() and Perl_warner().Nicholas Clark2009-10-121-6/+6
| | | | | Replace ckWARN_d{,2,3,4}() && Perl_warner() with it, which trades reduced code size for 1 more function call if warnings are not enabled.
* Perl_newHVhv() should copy immortal values as-is, such as PL_sv_undefNicholas Clark2009-08-201-3/+5
| | | | | | | | | | | | Currently it calls newSVsv() always, which copies the value, but the immortal SVs are used as much for their addresses as their values. You can't get the immortals into HVs from Perl-space, except for PL_sv_placeholder, and any hash with those will take the else block, where the call to Perl_hv_iternext_flags() won't be returning placeholders anyway. Hence If XS code has gone to the trouble to get the "impossible" in there, they had a reason for it. I am assuming that Perl_hv_copy_hints_hv() should stay as-is, as it is documented that only strings and integers are supported values for %^H.
* Instead of a const char *, pass a HEK * to anonymise_cv().Nicholas Clark2009-06-221-6/+11
| | | | | This will cope properly with Unicode package names. It also allows use of more efficient perl API calls, avoiding any strlen()s.

| | | | Change its callers to take advantage of this.
* Add a key flag HVhek_KEYCANONICAL for Perl_hv_common(), which signals that theNicholas Clark2008-12-281-2/+6
| | | | | | key is in canonical form - any key passed encoded in UTF-8 cannot be represented as bytes, hence the downgrade check can be skipped. Use this internally for shared hash key scalars, as they are always canonical.
* Precomputing the hash value for a string representable in bytes, but passed inNicholas Clark2008-12-281-0/+5
| | | | | in UTF-8, would result in storing the wrong hash value in the hash, and hence failing lookups. I guess not that much XS code precomputes hash values.

* Optimisation of the use of the meta structure - don't create a hash if all weNicholas Clark2008-12-271-1/+11

* Repurpose struct mro_meta to allow it to store cached linear ISA for arbitaryNicholas Clark2008-12-271-1/+0
| | | | | | | method resolution orders. mro_linear_dfs becomes a hash holding the different MROs' private data. mro_linear_c3 becomes a shortcut pointer to the current MRO's private data.

| | | | | | | | | | | de-duping hash used by S_mro_get_linear_isa_dfs(). Provide a new function Perl_get_isa_hash() to lazily retrieve this. (Which could actually be static if S_isa_lookup() and Perl_sv_derived_from() moved into mro.c.) Make S_isa_lookup() use this lookup hash in place of a linear walk of the linear isa. This should turn isa lookups from O(n) to O(1), which should make heavy users of ->isa() faster. (eg PPI, and hence Perl Critic). p4raw-id: //depot/perl@34354

* [perl #56908] DBI memory leak in 5.10.0 due to change 26530Dave Mitchell2008-08-201-0/+1
| | | | | | | | | | | A weakref to a HV would leak, because the xhv_backreferences array is created with a refcount of 2 (to avoid premature freeing during global destruction), but the RC was only decremented once when the parent HV was freed. Also, when thread cloned, the new array was being created with a RC of 1, rather than 2, which coincidentally worked due to the first bug. p4raw-id: //depot/perl@34209

We've already done this at least twice. (Yes, some of the assertions are after code that would already have SEGVd because it already deferences a pointer, but they are put in to make it easier to automate checking that each and every case is covered.)

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.
