* Fix escaping in opcode.h generationDagfinn Ilmari Mannsåker (via RT)2010-08-251-1/+1
| | | | | | The op list has no escapes, so there's no need check for already-escaped characters, and the existing regex breaks any run of consecutive backslashes, escaped or not.
* srand: change to return its seedKarl Williamson2010-07-281-1/+1
| | | | | | | | | | | | | | This commit changes srand to to return the seed instead of always returning 1. The motivation behind this is to allow applications to not have to come up with their own pseudo-random generator if they want repeatable results. The previous return behavior has never been documented. Note that it is possible, but very unlikely, for the seed to end up being 0, which means that if someone were relying on the undocumented previous behavior of srand returning true, that in very rare instances it would return 0, failing, and the next time they ran it, it would succeed, possibly leading to puzzlement and very rare unexplained failures.
* Make eval {} compile directly to OP_ENTERTRYRafael Garcia-Suarez2009-12-201-1/+1
| | | | | This way, it's correctly caught and blocked by Safe, separately from eval "".
* Move the boolkeys op to the group of hash ops.Nicholas Clark2009-10-151-2/+1
| | | | This breaks binary compatibility.
* Optimise if (%foo) to be faster than if(keys %foo)demerphq2009-10-151-0/+2
| | | | | | | | | | | Thread was "[PATCH] Make if (%hash) {} act the same as if (keys %hash) {}" http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2006-11/msg00432.html but the implementation evolved from the approach described in the subject, to instead add a new opcode pp_boolkeys, to exactly preserve the existing behaviour. Various conflicts with the passage of time resolved, 'register' removed, and a $VERSION bump.

| | | | | | | | Thanks to the wisdom of london.pm, stuff the filename into the SCALAR slot of the typeglob created in safer_open(), so that ... Add safer_close(), that will die (with the filename) if the close fails. p4raw-id: //depot/perl@33539
* Rename safer_rename() to rename_if_different(), to accurately describeNicholas Clark2008-03-151-42/+38
| | | | | | | | | | | | | what it does. Use File::Compare rather than Digest::MD5, as the files are small enough to simply read in. (File::Compare dates from 5.004) Remove safer_rename_always(), which isn't used. DRY by replacing the cargo-culted "open or die" with a new function safer_open(), which uses Gensym (5.002) to create an anonymous file handle, and opens and binmodes the file, or dies. This necessitates replacing bareword file handles with lexicals in all the callers. Correct the names of files in close or die constructions. p4raw-id: //depot/perl@33538

* Make state $zok = slosh(); behave as the Perl 6 design with an implicitNicholas Clark2007-09-061-0/+4
| | | | | | | | | | | | | | | START block. First time through, call slosh() and assign to $zok. Subsequently neither call slosh() nor assign to $zok. Adds a new op ONCE to control the conditonal call and assign. No change to list context, so state ($zok) = slosh() and (state $zok) = ... etc will still repeatedly evaluate and assign. [Can't fix that before 5.10] Use as an RVALUE is as Larry's design - my $boff = state $zok = ...; will evaluate, assign and return first time, and subsequently act as if it were written my $boff = $zok; FIXME - state $zok = ...; won't deparse - I believe op->op_last isn't being correctly set on the sassign, but I don't know how to fix this. This change may be backed out before 5.10. p4raw-id: //depot/perl@31798
