16 | This document describes differences between the 5.15.4 release and |
17 | the 5.15.5 release. | |
5cd408a2 | 18 | |
3432e5a1 | 19 | If you are upgrading from an earlier release such as 5.15.3, first read |
e3c71926 | 20 | L<perl5154delta>, which describes differences between 5.15.3 and |
3432e5a1 | 21 | 5.15.4. |

33 | =head2 C<$[> is back |
34 | ||
35 | The C<$[> variable is back again, but is now implemented as a module, so | |
36 | programs that do not mention it (i.e., most of them), will not incur any | |
37 | run-time penalty. It is disabled in the scope of C<use v5.16>. | |
38 | ||
39 | XXX That last sentence is not true yet. | |
40 | ||
41 | The new implementation has some bug fixes. See L<arybase>. | |

68 | =head2 Don't read the Unicode data base files in F<lib/unicore> |
69 | ||
70 | It is now deprecated to directly read the Unicode data base files. | |
71 | These are stored in the F<lib/unicore> directory. Instead, you should | |
72 | use the new functions in L<Unicode::UCD>. These provide a stable API, | |
73 | and give complete information. Perl may at some point in the future | |
74 | change or remove the files. The most likely of these files to be used | |
75 | is F<lib/unicore/ToDigit.pl>. L<Unicode::UCD/prop_invmap()> can be used | |
76 | to get at its data instead. | |

89 | Due to changes in L<File::Glob>, Perl's C<glob> function and its |
90 | C<< <...> >> equivalent are now much faster. The splitting of the pattern | |
91 | into words has been rewritten in C, resulting in speed-ups of 20% in some | |
92 | cases. | |
93 | ||
94 | This does not affect VMS, as it does not use File::Glob. | |

178 | L<File::Glob> has been upgrade from version 1.13 to 1.14. |
179 | ||
180 | It has a new C<:bsd_glob> export tag, intended to replace C<:glob>. Like | |
181 | C<:glob> it overrides C<glob> with a function that does not split the glob | |
182 | pattern into words, but, unlike C<:glob>, it iterates properly in scalar | |
183 | context, instead of returning the last file. | |
184 | ||
185 | There are other changes affecting Perl's own C<glob> operator (which uses | |
186 | File::Glob internally, except on VMS). See L</Performance Enhancements> | |

462 | Perl now holds an extra reference count on the package that code is |
463 | currently compiling in. This means that the following code no longer crashes [perl #101486]: | |
464 | ||
465 | package Foo; | |
466 | BEGIN {*Foo:: = *Bar::} | |
467 | sub foo; | |
468 | ||
469 | =item * | |
470 | ||
471 | F<dumpvar.pl>, and consequently the C<x> command in the debugger, have been | |
472 | fixed to handle objects blessed into classes whose names contain "=". The | |
473 | contents of such objects used not to be dumped [perl #101814]. | |
474 | ||
475 | =item * | |
476 | ||
477 | The C<x> repetition operator no longer crashes on 64-bit builds with large | |
478 | repeate counts [perl #94560]. | |
479 | ||
480 | =item * | |
481 | ||
482 | A fix to C<glob> under miniperl (used to configure modules when perl itself | |
483 | is built) in Perl 5.15.3 stopped C<< <~> >> from returning the home | |
484 | directory, because it cleared %ENV before calling csh. Now C<$ENV{HOME}> | |
485 | is preserved. This fix probably does not affect anything. If | |
486 | L<File::Glob> fails to load for some reason, Perl reverts to using csh. | |
487 | So it would apply in that case. | |
488 | ||
489 | =item * | |
490 | ||
491 | On OSes other than VMS, Perl's C<glob> operator (and the C<< <...> >> form) | |
492 | use L<File::Glob> underneath. L<File::Glob> splits the pattern into words, | |
493 | before feeding each word to its C<bsd_glob> function. | |
494 | ||
495 | There were several inconsistencies in the way the split was done. Now | |
496 | quotation marks (' and ") are always treated as shell-style word delimiters | |
497 | (that allow whitespace as part of a word) and backslashes are always | |
498 | preserved, unless they exist to escape quotation marks. Before, those | |
499 | would only sometimes be the case, depending on whether the pattern | |
500 | contained whitespace. Also, escaped whitespace at the end of the pattern | |
501 | is no longer stripped. | |
502 | ||
503 | =item * | |
504 | ||
505 | C<CORE::glob> now works as a way to call the default globbing function. It | |
506 | used to respect overrides, despite the C<CORE::> prefix. | |
507 | ||
508 | =item * | |
509 | ||
510 | In 5.14, C</[[:lower:]]/i> and C</[[:upper:]]/i> no longer matched the | |
511 | opposite case. This has been fixed [perl #101970]. | |
512 | ||

514 | ||
515 | A regular expression match with an overloaded object on the right-hand side | |
516 | would in some cases stringify the object too many times. | |
517 | ||
518 | =item * | |
519 | ||
520 | The C-level C<pregcomp> function could become confused as to whether the | |
521 | pattern was in UTF8 if the pattern was an overloaded, tied, or otherwise | |
522 | magical scalar [perl #101940]. | |

525 | ||
526 | A regression has been fixed that was introduced in 5.14, in C</i> | |
527 | regular expression matching, in which a match improperly fails if the | |
528 | pattern is in UTF-8, the target string is not, and a Latin-1 character | |
529 | precedes a character in the string that should match the pattern. [perl | |
530 | #101710] | |

564 | =head1 Reporting Bugs |
565 | ||
566 | If you find what you think is a bug, you might check the articles | |
34dc2ec0 | 567 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
44691e6f AB |
568 | bug database at http://rt.perl.org/perlbug/ . There may also be |
569 | information at http://www.perl.org/ , the Perl Home Page. | |
570 | ||
571 | If you believe you have an unreported bug, please run the L<perlbug> | |
572 | program included with your release. Be sure to trim your bug down | |
573 | to a tiny but sufficient test case. Your bug report, along with the | |
574 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
575 | analysed by the Perl porting team. | |
576 | ||
577 | If the bug you are reporting has security implications, which make it | |
578 | inappropriate to send to a publicly archived mailing list, then please send | |
34dc2ec0 | 579 | it to perl5-security-report@perl.org. This points to a closed subscription |
b4707b2a FC |
580 | unarchived mailing list, which includes |
581 | all the core committers, who will be able | |
44691e6f AB |
582 | to help assess the impact of issues, figure out a resolution, and help |
583 | co-ordinate the release of patches to mitigate or fix the problem across all | |
34dc2ec0 DM |
584 | platforms on which Perl is supported. Please only use this address for |
585 | security issues in the Perl core, not for modules independently | |
