5 | perl5139delta - what is new for perl v5.13.9 | |
6 | ||
7 | =head1 DESCRIPTION | |
8 | ||
9 | This document describes differences between the 5.13.8 release and | |
10 | the 5.13.9 release. | |
11 | ||
12 | If you are upgrading from an earlier release such as 5.13.7, first read | |
13 | L<perl5138delta>, which describes differences between 5.13.7 and | |
14 | 5.13.8. | |

16 | =head1 Core Enhancements | |

18 | =head2 New regular expression modifier C</a> | |
19 | ||
20 | The C</a> regular expression modifier restricts C<\s> to match precisely | |
21 | the five characters C<[ \f\n\r\t]>, C<\d> to match precisely the 10 | |
22 | characters C<[0-9]>, C<\w> to match precisely the 63 characters | |
23 | C<[A-Za-z0-9_]>, and the Posix (C<[[:posix:]]>) character classes to | |
24 | match only the appropriate ASCII characters. The complements, of | |
25 | course, match everything but; and C<\b> and C<\B> are correspondingly | |
26 | affected. Otherwise, C</a> behaves like the C</u> modifier, in that | |
27 | case-insensitive matching uses Unicode semantics; for example, "k" will | |
28 | match the Unicode C<\N{KELVIN SIGN}> under C</i> matching, and code | |
29 | points in the Latin1 range, above ASCII will have Unicode semantics when | |
30 | it comes to case-insensitive matching. Like its cousins (C</u>, C</l>, | |
31 | and C</d>), and in spite of the terminology, C</a> in 5.14 will not | |
32 | actually be able to be used as a suffix at the end of a regular | |
33 | expression (this restriction is planned to be lifted in 5.16). It must | |
34 | occur either as an infix modifier, such as C<(?a:...)> or (C<(?a)...>, | |
35 | or it can be turned on within the lexical scope of C<use re '/a'>. | |
36 | Turning on C</a> turns off the other "character set" modifiers. | |
37 | ||
38 | =head2 Any unsigned value can be encoded as a character | |
39 | ||
40 | With this release, Perl is adopting a model that any unsigned value can | |
41 | be treated as a code point and encoded internally (as utf8) without | |
42 | warnings -- not just the code points that are legal in Unicode. | |
43 | However, unless utf8 warnings have been | |
44 | explicitly lexically turned off, outputting or performing a | |
45 | Unicode-defined operation (such as upper-casing) on such a code point | |
46 | will generate a warning. Attempting to input these using strict rules | |
47 | (such as with the C<:encoding('UTF-8')> layer) will continue to fail. | |
48 | Prior to this release the handling was very inconsistent, and incorrect | |
49 | in places. Also, the Unicode non-characters, some of which previously were | |
50 | erroneously considered illegal in places by Perl, contrary to the Unicode | |
51 | standard, are now always legal internally. But inputting or outputting | |
52 | them will work the same as for the non-legal Unicode code points, as the | |
53 | Unicode standard says they are illegal for "open interchange". | |
54 | ||
55 | =head2 Regular expression debugging output improvement | |
56 | ||
57 | Regular expression debugging output (turned on by C<use re 'debug';>) now | |
58 | uses hexadecimal when escaping non-ASCII characters, instead of octal. | |
59 | ||
60 | =head1 Security | |
61 | ||
62 | =head2 Restrict \p{IsUserDefined} to In\w+ and Is\w+ | |
63 | ||
64 | In L<perlunicode/"User-Defined Character Properties">, it says you can | |
65 | create custom properties by defining subroutines whose names begin with | |
66 | "In" or "Is". However, perl doesn't actually enforce that naming | |
67 | restriction, so \p{foo::bar} will call foo::Bar() if it exists. | |
68 | ||
69 | This commit finally enforces this convention. Note that this broke a | |
70 | number of existing tests for properties, since they didn't always use an | |
71 | Is/In prefix. | |
72 | ||
73 | =head1 Incompatible Changes | |
74 | ||
75 | =head2 All objects are destroyed | |
76 | ||
77 | It used to be possible to prevent a destructor from being called during | |
78 | global destruction by artificially increasing the reference count of an | |
79 | object. | |
80 | ||
81 | Now such objects I<will> will be destroyed, as a result of a bug fix | |
82 | L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>. | |
83 | ||
84 | This has the potential to break some XS modules. (In fact, it break some. | |
85 | See L</Known Problems>, below.) | |

94 | ||
95 | C<CPAN::Meta::YAML> 0.003 has been added as a dual-life module. It supports a | |
96 | subset of YAML sufficient for reading and writing META.yml and MYMETA.yml files | |
97 | included with CPAN distributions or generated by the module installation | |
98 | toolchain. It should not be used for any other general YAML parsing or | |
99 | generation task. | |
100 | ||
101 | =item * | |
102 | ||
103 | C<HTTP::Tiny> 0.009 has been added as a dual-life module. It is a very | |
104 | small, simple HTTP/1.1 client designed for simple GET requests and file | |
105 | mirroring. It has has been added to enable CPAN.pm and CPANPLUS to | |
106 | "bootstrap" HTTP access to CPAN using pure Perl without relying on external | |
107 | binaries like F<curl> or F<wget>. | |
108 | ||
109 | =item * | |
110 | ||
111 | C<JSON::PP> 2.27103 has been added as a dual-life module, for the sake of | |
112 | reading F<META.json> files in CPAN distributions. | |
113 | ||
114 | =item * | |
115 | ||
116 | C<Module::Metadata> 1.000003 has been added as a dual-life module. It gathers | |
117 | package and POD information from Perl module files. It is a standalone module | |
118 | based on Module::Build::ModuleInfo for use by other module installation | |
119 | toolchain components. Module::Build::ModuleInfo has been deprecated in | |
120 | favor of this module instead. | |
121 | ||
122 | =item * | |
123 | ||
124 | C<Perl::OSType> 1.002 has been added as a dual-life module. It maps Perl | |
125 | operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic types | |
126 | with standardized names (e.g. "Unix" or "Windows"). It has been refactored | |
127 | out of Module::Build and ExtUtils::CBuilder and consolidates such mappings into | |
128 | a single location for easier maintenance. | |

458 | The opcode bodies for C<chop> and C<chomp> and for C<schop> and C<schomp> have | |
459 | been merged. The implementation functions C<Perl_do_chop()> and | |
460 | C<Perl_do_chomp()>, never part of the public API, have been merged and moved to | |
461 | a static function in F<pp.c>. This shrinks the perl binary slightly, and should | |
462 | not affect any code outside the core (unless it is relying on the order of side | |
463 | effects when C<chomp> is passed a I<list> of values). | |

465 | =item * | |
466 | ||
467 | Some of the flags parameters to the uvuni_to_utf8_flags() and | |
468 | utf8n_to_uvuni() have changed. This is a result of Perl now allowing | |
469 | internal storage and manipulation of code points that are problematic | |
470 | in some situations. Hence, the default actions for these functions has | |
471 | been complemented to allow these code points. The new flags are | |
472 | documented in L<perlapi>. Code that requires the problematic code | |
473 | points to be rejected needs to change to use these flags. Some flag | |
474 | names are retained for backward source compatibility, though they do | |
475 | nothing, as they are now the default. However the flags | |
476 | C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and | |
477 | C<UNICODE_IS_ILLEGAL> have been removed, as they stem from a | |
478 | fundamentally broken model of how the Unicode non-character code points | |
479 | should be handled, which is now described in | |
480 | L<perlunicode/Non-character code points>. See also L</Selected Bug Fixes>. | |

482 | =item * | |
483 | ||
484 | Certain shared flags in the C<pmop.op_pmflags> and C<regexp.extflags> | |
485 | structures have been removed. These are: C<Rxf_Pmf_LOCALE>, | |
486 | C<Rxf_Pmf_UNICODE>, and C<PMf_LOCALE>. Instead there are encodes and | |
487 | three static in-line functions for accessing the information: | |
488 | C<get_regex_charset()>, C<set_regex_charset()>, and C<get_regex_charset_name()>, | |
489 | which are defined in the places where the orginal flags were. | |

493 | A new option has been added to C<pv_escape> to dump all characters above | |

506 | pp_proto.h. It no longer writes pp.sym, and regen/embed.pl no longer reads | |
507 | this, removing the only ordering dependency in the regen scripts. opcode.pl | |

519 | The handling of Unicode non-characters has changed. | |
520 | Previously they were mostly considered illegal, except that only one of | |

532 | Sometimes magic (ties, tainted, etc.) attached to variables could cause an | |
533 | object to last longer than it should, or cause a crash if a tied variable | |
534 | were freed from within a tie method. These have been fixed | |
535 | L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>. | |

539 | Most I/O functions were not warning for unopened handles unless the | |
540 | 'closed' and 'unopened' warnings categories were both enabled. Now only | |
541 | C<use warnings 'unopened'> is necessary to trigger these warnings (as was | |
542 | always meant to be the case. | |

545 | ||
546 | C<< E<lt>exprE<gt> >> always respects overloading now if the expression is | |
547 | overloaded. | |
548 | ||
549 | Due to the way that 'E<lt>E<gt> as glob' was parsed differently from | |
550 | 'E<lt>E<gt> as filehandle' from 5.6 onwards, something like C<< E<lt>$foo[0]E<gt> >> did | |
551 | not handle overloading, even if C<$foo[0]> was an overloaded object. This | |
552 | was contrary to the documentation for overload, and meant that C<< E<lt>E<gt> >> | |
553 | could not be used as a general overloaded iterator operator. | |

557 | Destructors on objects were not called during global destruction on objects | |
558 | that were not referenced by any scalars. This could happen if an array | |
559 | element were blessed (e.g., C<bless \$a[0]>) or if a closure referenced a | |
560 | blessed variable (C<bless \my @a; sub foo { @a }>). | |
561 | ||
562 | Now there is an extra pass during global destruction to fire destructors on | |
563 | any objects that might be left after the usual passes that check for | |
564 | objects referenced by scalars | |

569 | A long standing bug has now been fully fixed (partial fixes came in | |
570 | earlier releases), in which some Latin-1 non-ASCII characters on | |
571 | ASCII-platforms would match both a character class and its complement, | |
572 | such as U+00E2 being both in C<\w> and C<\W>, depending on the | |
573 | UTF-8-ness of the regular expression pattern and target string. | |
574 | Fixing this did expose some bugs in various modules and tests that | |
575 | relied on the previous behavior of C<[[:alpha:]]> not ever matching | |
576 | U+00FF, "LATIN SMALL LETTER Y WITH DIAERESIS", even when it should, in | |
577 | Unicode mode; now it does match when appropriate. | |

612 | =head1 Reporting Bugs | |
613 | ||
614 | If you find what you think is a bug, you might check the articles | |
615 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
616 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
617 | information at http://www.perl.org/ , the Perl Home Page. | |
618 | ||
619 | If you believe you have an unreported bug, please run the L<perlbug> | |
620 | program included with your release. Be sure to trim your bug down | |
621 | to a tiny but sufficient test case. Your bug report, along with the | |
622 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
623 | analysed by the Perl porting team. | |
624 | ||
625 | If the bug you are reporting has security implications, which make it | |
626 | inappropriate to send to a publicly archived mailing list, then please send | |
627 | it to perl5-security-report@perl.org. This points to a closed subscription | |
628 | unarchived mailing list, which includes all the core committers, who be able | |
629 | to help assess the impact of issues, figure out a resolution, and help | |
630 | co-ordinate the release of patches to mitigate or fix the problem across all | |
631 | platforms on which Perl is supported. Please only use this address for | |
632 | security issues in the Perl core, not for modules independently | |
633 | distributed on CPAN. | |
