5 | perldelta - what is new for perl v5.13.5 |
6 | ||
7 | =head1 DESCRIPTION | |
8 | ||
9 | This document describes differences between the 5.13.4 release and | |
10 | the 5.13.5 release. | |
11 | ||
12 | If you are upgrading from an earlier release such as 5.13.3, first read | |
13 | L<perl5134delta>, which describes differences between 5.13.3 and | |
14 | 5.13.4. | |

18 | =head2 Adjacent pairs of nextstate opcodes are now optimized away |
19 | ||
20 | Previously, in code such as | |
21 | ||
22 | use constant DEBUG => 0; | |
23 | ||
24 | sub GAK { | |
25 | warn if DEBUG; | |
26 | print "stuff\n"; | |
27 | } | |
28 | ||
29 | the ops for C<warn if DEBUG;> would be folded to a C<null> op (C<ex-const>), but | |
30 | the C<nextstate> op would remain, resulting in a runtime op dispatch of | |
31 | C<nextstate>, C<nextstate>, ... | |
32 | ||
7bc3efda SH |
33 | The execution of a sequence of C<nextstate> ops is indistinguishable from just |
34 | the last C<nextstate> op so the peephole optimizer now eliminates the first of | |
35 | a pair of C<nextstate> ops, except where the first carries a label, since labels | |
36 | must not be eliminated by the optimizer and label usage isn't conclusively known | |
37 | at compile time. | |

39 | =head2 API function to parse statements |
40 | ||
41 | The C<parse_fullstmt> function has been added to allow parsing of a single | |
7bc3efda | 42 | complete Perl statement. See L<perlapi> for details. |
85318b69 FR |
43 | |
44 | =head2 API functions for accessing the runtime hinthash | |
45 | ||
7bc3efda SH |
46 | A new C API for introspecting the hinthash C<%^H> at runtime has been added. |
47 | See C<cop_hints_2hv>, C<cop_hints_fetchpvn>, C<cop_hints_fetchpvs>, | |
78846812 | 48 | C<cop_hints_fetchsv>, and C<hv_copy_hints_hv> in L<perlapi> for details. |

50 | =head2 C interface to C<caller()> | |
51 | ||
52 | The C<caller_cx> function has been added as an XSUB-writer's equivalent of | |
7bc3efda | 53 | C<caller()>. See L<perlapi> for details. |

56 | ||
7bc3efda | 57 | =head2 Magic variables outside the main package |
44428a46 | 58 | |
7bc3efda SH |
59 | In previous versions of Perl, magic variables like C<$!>, C<%SIG>, etc. would |
60 | 'leak' into other packages. So C<%foo::SIG> could be used to access signals, | |
44428a46 FC |
61 | C<${"foo::!"}> (with strict mode off) to access C's C<errno>, etc. |
62 | ||
7bc3efda SH |
63 | This was a bug, or an 'unintentional' feature, which caused various ill effects, |
64 | such as signal handlers being wiped when modules were loaded, etc. | |
44428a46 | 65 | |
7bc3efda SH |
66 | This has been fixed (or the feature has been removed, depending on how you see |
67 | it). | |

69 | =head2 Smart-matching against array slices |
70 | ||
71 | Previously, the following code resulted in a successful match: | |
72 | ||
73 | my @a = qw(a y0 z); | |
74 | my @b = qw(a x0 z); | |
75 | $a[0 .. $#b] ~~ @b; | |
76 | ||
ebce6c40 FR |
77 | This odd behaviour has now been fixed |

d6747b7a | 80 | =head2 C API changes |
4c793fe3 | 81 | |
d6747b7a NC |
82 | The first argument of the C API function C<Perl_fetch_cop_label> has changed |
83 | from C<struct refcounted he *> to C<COP *>, to better insulate the user from | |
84 | implementation details. | |
4c793fe3 | 85 | |
d6747b7a | 86 | This API function was marked as "may change", and likely isn't in use outside |
7bc3efda | 87 | the core. (Neither an unpacked CPAN, nor Google's codesearch, finds any other |
d6747b7a | 88 | references to it.) |

90 | =head1 Deprecations | |
91 | ||
85318b69 FR |
92 | =head2 Use of qw(...) as parentheses |
93 | ||
94 | Historically the parser fooled itself into thinking that C<qw(...)> literals | |
95 | were always enclosed in parentheses, and as a result you could sometimes omit | |
96 | parentheses around them: | |
97 | ||
98 | for $x qw(a b c) { ... } | |
99 | ||
100 | The parser no longer lies to itself in this way. Wrap the list literal in | |
101 | parentheses, like: | |
102 | ||
103 | for $x (qw(a b c)) { ... } | |

354 | When C<perlio> became the default and C<unixio> became the default bottom layer, |

441 | Opening a glob reference via C<< open $fh, "E<gt>", \*glob >> will no longer |

463 | Perl would segfault if the undocumented C<Internals> functions that used |

7bc3efda | 483 | An earlier release of the 5.13 series of Perl changed the semantics of opening a |
e2babdfb FR |
484 | reference to a copy of a glob: |
485 | ||
486 | my $var = *STDOUT; | |
487 | open my $fh, '>', \$var; | |
488 | ||
7bc3efda | 489 | This was a mistake, and the previous behaviour from Perl 5.10 and 5.12, which is |
e2babdfb FR |
490 | to treat \$var as a scalar reference, has now been restored. |

494 | The regular expression bracketed character class C<[\8\9]> was effectively the |
495 | same as C<[89\000]>, incorrectly matching a NULL character. It also gave | |
496 | incorrect warnings that the C<8> and C<9> were ignored. Now C<[\8\9]> is the | |
497 | same as C<[89]> and gives legitimate warnings that C<\8> and C<\9> are | |
498 | unrecognized escape sequences, passed-through. | |

547 | =head1 Reporting Bugs | |
548 | ||
549 | If you find what you think is a bug, you might check the articles | |
550 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
551 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
552 | information at http://www.perl.org/ , the Perl Home Page. | |
553 | ||
554 | If you believe you have an unreported bug, please run the B<perlbug> | |
555 | program included with your release. Be sure to trim your bug down | |
556 | to a tiny but sufficient test case. Your bug report, along with the | |
557 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
558 | analysed by the Perl porting team. | |
559 | ||
560 | If the bug you are reporting has security implications, which make it | |
561 | inappropriate to send to a publicly archived mailing list, then please send | |
7bc3efda | 562 | it to perl5-security-report@perl.org. This points to a closed subscription |
4c793fe3 FR |
563 | unarchived mailing list, which includes all the core committers, who be able |
564 | to help assess the impact of issues, figure out a resolution, and help | |
565 | co-ordinate the release of patches to mitigate or fix the problem across all | |
7bc3efda | 566 | platforms on which Perl is supported. Please only use this address for |
4c793fe3 FR |
567 | security issues in the Perl core, not for modules independently |
568 | distributed on CPAN. | |
