* [perl #91614] Suggestion for improving documentation of $!John P. Linderman2011-05-251-15/+18
| | | | | | | | | | | | | | | | | | While trying to understand a bug report at http://www.perlmonks.org/?node_id=906466 I realized that the documentation for $! was not crystal clear. For example If used numerically, yields the current value of the C C<errno> variable, or in other words, if a system or library call fails, it sets this variable. That's not "in other words", these are totally different concepts. And it isn't clear whether this variable refers to errno or $! (I assumed the latter, and was wrong, as Devel::Peek demonstrated). And $! cannot be undef, as asserted (later), because errno always contains a value, however irrelevant.

* [perl #91508] __DATA__ starts reading on the next lineJohan Vromans2011-05-241-1/+1
| | | | | | | | | | | | | | | In pod/perldata it is described that the DATA filehandle starts reading after the __DATA__ token. In reality, it starts reading on the line following the __DATA__ token. Example: print while <DATA>; __DATA__ foo bar This prints "bar", not "foo\nbar". The attached patch fixes the documentation in pod/perldata.pod.

* Use L<> rather than C<> in the Updated Modules section of perldelta.Nicholas Clark2011-05-201-2/+2
| | | | | | | | | | Previous perldeltas have been inconsistent with each other as to whether to use L<> to C<> (but internally consistent). perldelta5140.pod uses L<>, which is more useful, as it provides a direct link to fuller documentation at the point where the reader is likely to want to follow it. Switch the two existing entries from C<> to L<>, and update the perldelta template to suggest L<>.

* remove 'hfreeentries failed to free hash' panicDavid Mitchell2011-05-191-7/+0
| | | | | | | | | | | | | | | | | | | Currently perl attempts to clear a hash 100 times before panicking. So for example, if a naughty destructor keeps adding things back into the hash, this will eventually panic. Note that this can usually only occur with %h=() or undef(%h), since when freeing a hash, there's usually no reference to the hash that a destructor can use to mess with the hash. Remove this limit (so it may potentially loop forever). My reasoning is that (a) if the user wants to keep adding things back into the hash, who are we to stop her? (b) as part of of the process of making sv_clear() non-recursive when freeing hashes, I'm trying to reduce the amount of state that must be maintained between each iteration. Note that arrays currently don't have a limit.

* [perl #89662] PATCH to perlfunc.pod: select fixTom Christiansen2011-05-181-9/+12
| | | | | | | | | | | | I think it's about time--by say 20 years--that we stop passing around filehandles as strings, especially if we don't use Symbol::qualify_to_ref() to fix the package. Plus it isn't strict-safe. All fixed now. I am somewhat concerned about the final comment regarding read and sysread, as I don't know whether PerlIO encoding translation issues affect this picture. --tom

| | | | | | | | | | | things, but does not address the "this version" != 5.14 and the perlio issues. I believe that these at least should be addressed as soon as possible (I don't know whether that means 5.14; probably not). It has to either say the particular version that applies. We can't keep releasing things that say this version: they are not trustable. --tom
* Store the compiled format in mg_ptr instead of after SvCUR() - fixes RT #89218Nicholas Clark2011-05-181-3/+5
| | | | | | | | | | | | | | | | | | | | | Formats are compiled down to a sequence of U32 opcodes in doparseform(). Previously the block of opcodes was stored in the buffer of SvPVX() after the raw string by extending the buffer, and calculating the first U32 aligned address after SvCUR(). A flag bit on the scalar was set to signal this hackery, tested with SvCOMPILED() The flag bit used happened to be the same as one of the two used by to signal Boyer-Moore compiled scalars. The assumption was that no scalar can be used for both. Unfortunately, this isn't quite true. Given that the scalar is alway upgraded to PVMG to add PERL_MAGIC_fm magic, to clear the cached compiled version, there's no extra memory cost in using mg_ptr in the MAGIC struct to point directly to the block of U32 opcodes. The test for "is there a compiled version" can switch to mg_find(..., PERL_MAGIC_fm) returning a pointer, and the use of a flag bit abolished. Retain SvCOMPILED() and SvCOMPILED_{on,off}() as compatibility for XS code on CPAN - the first is always 0, the other two now no-ops.
