* Clean: Actually use HvUSEDKEYS() instead of HvKEYS()Michael Witten2011-05-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This: commit 8aacddc1ea3837f8f1a911d90c644451fc7cfc86 Author: Nick Ing-Simmons <nik@tiuk.ti.com> Date: Tue Dec 18 15:55:22 2001 +0000 Tidied version of Jeffrey Friedl's <jfriedl@yahoo.com> restricted hashes - added delete of READONLY value inhibit & test for same - re-tabbed p4raw-id: //depot/perlio@13760 essentially deprecated HvKEYS() in favor of HvUSEDKEYS(); this is explained in line 144 (now 313) of file `hv.h': /* * HvKEYS gets the number of keys that actually exist(), and is provided * for backwards compatibility with old XS code. The core uses HvUSEDKEYS * (keys, excluding placeholdes) and HvTOTALKEYS (including placeholders) */ This commit simply puts that into practice, and is equivalent to running the following (at least with a35ef416833511da752c4b5b836b7a8915712aab checked out): git grep -l HvKEYS | sed /hv.h/d | xargs sed -i s/HvKEYS/HvUSEDKEYS/ Notice that HvKEYS is currently just an alias for HvUSEDKEYS: $ git show a35ef416833511da752c4b5b836b7a8915712aab:hv.h | sed -n 318p #define HvKEYS(hv) HvUSEDKEYS(hv) According to `make tests': All tests successful.
* [perl #82250] fix tainted (s)print formatDavid Mitchell2011-03-141-0/+8
| | | | | | | | | | | | commit 20ee07fbbcfa6be9f90bb8e5474a4d69d7396617 introduced dieing in (s)printf when the format is tainted; however it only worked when the format is part of an expression (because TAINT_PROPER checks for PL_tainted being set). Fix by doing TAINT_PROPER only after get magic has been done on the format SV (which will set PL_tainted). This is done by moving the checks in pp_sprintf and pp_prtf into do_sprintf() (which is called by the two pp functions).
* Move do_chomp() from pp.c to doop.c, and make it static.Nicholas Clark2010-12-271-167/+0
| | | | It was never part of the public API, and only ever used by pp_{s,}cho{,m}p.
* Merge Perl_do_chop() and Perl_do_chomp().Nicholas Clark2010-12-271-90/+45
| | | | | | They share code for dealing with PVAVs, PVHVs, read only values and handling PL_encoding. They are not part of the public API, and Google codesearch shows no users outside the core.
* Convert Perl_do_chomp() to the same prototype as Perl_do_chop().Nicholas Clark2010-12-271-15/+12
| | | | Pass in an SV to hold the count, rather than returning the count.
* Allow push/pop/keys/etc to act on referencesDavid Golden2010-10-311-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All built-in functions that operate directly on array or hash containers now also accept hard references to arrays or hashes: |----------------------------+---------------------------| | Traditional syntax | Terse syntax | |----------------------------+---------------------------| | push @$arrayref, @stuff | push $arrayref, @stuff | | unshift @$arrayref, @stuff | unshift $arrayref, @stuff | | pop @$arrayref | pop $arrayref | | shift @$arrayref | shift $arrayref | | splice @$arrayref, 0, 2 | splice $arrayref, 0, 2 | | keys %$hashref | keys $hashref | | keys @$arrayref | keys $arrayref | | values %$hashref | values $hashref | | values @$arrayref | values $arrayref | | ($k,$v) = each %$hashref | ($k,$v) = each $hashref | | ($k,$v) = each @$arrayref | ($k,$v) = each $arrayref | |----------------------------+---------------------------| This allows these built-in functions to act on long dereferencing chains or on the return value of subroutines without needing to wrap them in C<@{}> or C<%{}>: push @{$obj->tags}, $new_tag; # old way push $obj->tags, $new_tag; # new way for ( keys %{$hoh->{genres}{artists}} ) {...} # old way for ( keys $hoh->{genres}{artists} ) {...} # new way For C<push>, C<unshift> and C<splice>, the reference will auto-vivify if it is not defined, just as if it were wrapped with C<@{}>. Calling C<keys> or C<values> directly on a reference gives a substantial performance improvement over explicit dereferencing. For C<keys>, C<values>, C<each>, when overloaded dereferencing is present, the overloaded dereference is used instead of dereferencing the underlying reftype. Warnings are issued about assumptions made in the following three ambiguous cases: (a) If both %{} and @{} overloading exists, %{} is used (b) If %{} overloading exists on a blessed arrayref, %{} is used (c) If @{} overloading exists on a blessed hashref, @{} is used
* [perl #76814] FETCH called twice - yFather Chrysostomos2010-09-241-6/+6
| | | | | This patch stops y from calling get-magic twice. (This has caused double magick since as far back as 5.6.2.)

* Add Perl_croak_no_modify() to implement Perl_croak("%s", PL_no_modify).Nicholas Clark2010-06-271-3/+3
| | | | | This reduces object code size, reducing CPU cache pressure on the non-exception paths.

* Add Perl_ck_warner(), which combines Perl_ckwarn() and Perl_warner().Nicholas Clark2009-10-121-9/+6
| | | | | | | Replace ckWARN{,2,3,4}() && Perl_warner() with it, which trades reduced code size (about 0.2%), for 1 more function call if warnings are not enabled. However, if we're now in the L1 or L2 cache when we weren't previously, that's still going to be a speed win.
* Remove all #ifdef MACOS_TRADITIONAL code in core and non-dual-life XS code.Nicholas Clark2009-04-271-4/+0
| | | | | | | | (MacOS support was removed from MakeMaker in 6.22, and merged to blead on 15th December 2004 with 5dca256ec738057dc331fb644a93eca44ad5fa14. After this point MacOS wouldn't even have been able to build the perl binary, because it would not have been able to build DynaLoader. If anyone wishes to resurrect MacOS, start by reversing this commit and the relevant part of that commit.)
