37 | =head2 C<-d:-foo> calls C<Devel::foo::unimport> |
38 | ||
39 | The syntax C<-dI<B<:>foo>> was extended in 5.6.1 to make C<-dI<:fooB<=bar>>> | |
6a8c8694 FC |
40 | equivalent to C<-MDevel::foo=bar>, which expands |
41 | internally to C<use Devel::foo 'bar';>. | |
b19934fb NC |
42 | F<perl> now allows prefixing the module name with C<->, with the same |
43 | semantics as C<-M>, I<i.e.> | |
44 | ||
45 | =over 4 | |
46 | ||
47 | =item C<-d:-foo> | |
48 | ||
6a8c8694 FC |
49 | Equivalent to C<-M-Devel::foo>, expands to |
50 | C<no Devel::foo;>, calls C<< Devel::foo->unimport() >> | |
b19934fb NC |
51 | if the method exists. |
52 | ||
53 | =item C<-d:-foo=bar> | |
54 | ||
6a8c8694 FC |
55 | Equivalent to C<-M-Devel::foo=bar>, expands to C<no Devel::foo 'bar';>, |
56 | calls C<< Devel::foo->unimport('bar') >> if the method exists. | |
b19934fb NC |
57 | |
58 | =back | |
59 | ||
60 | This is particularly useful to suppresses the default actions of a | |
61 | C<Devel::*> module's C<import> method whilst still loading it for debugging. | |
62 | ||
15e6cdd9 DG |
63 | =head2 Filehandle method calls load IO::File on demand |
64 | ||
65 | When a method call on a filehandle would die because the method can not | |
66 | be resolved and L<IO::File> has not been loaded, Perl now loads IO::File | |
67 | via C<require> and attempts method resolution again: | |
68 | ||
69 | open my $fh, ">", $file; | |
70 | $fh->binmode(":raw"); # loads IO::File and succeeds | |
71 | ||
72 | This also works for globs like STDOUT, STDERR and STDIN: | |
73 | ||
74 | STDOUT->autoflush(1); | |
75 | ||
76 | Because this on-demand load only happens if method resolution fails, the | |
77 | legacy approach of manually loading an IO::File parent class for partial | |
78 | method support still works as expected: | |
79 | ||
80 | use IO::Handle; | |
81 | open my $fh, ">", $file; | |
82 | $fh->autoflush(1); # IO::File not loaded | |

84 | =head2 Full functionality for C<use feature 'unicode_strings'> |
85 | ||
86 | This release provides full functionality for C<use feature | |
87 | 'unicode_strings'>. Under its scope, all string operations executed and | |
88 | regular expressions compiled (even if executed outside its scope) have | |
89 | Unicode semantics. See L<feature>. | |
90 | ||
91 | This feature avoids the "Unicode Bug" (See | |
92 | L<perlunicode/The "Unicode Bug"> for details.) If their is a | |
93 | possibility that your code will process Unicode strings, you are | |
94 | B<strongly> encouraged to use this subpragma to avoid nasty surprises. | |

96 | =head2 Exception Handling Backcompat Hack |
97 | ||
98 | When an exception is thrown in an C<eval BLOCK>, C<$@> is now set before | |
99 | unwinding, as well as being set after unwinding as the eval block exits. This | |
100 | early setting supports code that has historically treated C<$@> during unwinding | |
101 | as an indicator of whether the unwinding was due to an exception. These modules | |
102 | had been broken by 5.13.1's change from setting C<$@> early to setting it late. | |
103 | This double setting arrangement is a stopgap until the reason for unwinding can | |
104 | be made properly introspectable. C<$@> has never been a reliable indicator of | |
105 | this. | |

2dc78664 | 117 | =head2 Attempting to use C<:=> as an empty attribute list is now a syntax error |
3a5c9134 | 118 | |
2dc78664 NC |
119 | Previously C<my $pi := 4;> was exactly equivalent to C<my $pi : = 4;>, |
120 | with the C<:> being treated as the start of an attribute list, ending before | |
121 | the C<=>. The use of C<:=> to mean C<: => was deprecated in 5.12.0, and is now | |
122 | a syntax error. This will allow the future use of C<:=> as a new token. | |
3a5c9134 | 123 | |
2dc78664 NC |
124 | We find no Perl 5 code on CPAN using this construction, outside the core's |
125 | tests for it, so we believe that this change will have very little impact on | |
126 | real-world codebases. | |
127 | ||
128 | If it is absolutely necessary to have empty attribute lists (for example, | |
baed7a72 NC |
129 | because of a code generator) then avoid the error by adding a space before |
130 | the C<=>. | |
3a5c9134 | 131 | |
d66e82e8 FC |
132 | =head2 Run-time code block in regular expressions |
133 | ||
134 | Code blocks in regular expressions (C<(?{...})> and C<(??{...})>) used not | |
135 | to inherit any pragmata (strict, warnings, etc.) if the regular expression | |
136 | was compiled at run time as happens in cases like these two: | |
137 | ||
138 | use re 'eval'; | |
139 | $foo =~ $bar; # when $bar contains (?{...}) | |
140 | $foo =~ /$bar(?{ $finished = 1 })/; | |
141 | ||
142 | This was a bug, which has now been fixed. But it has the potential to break | |
143 | any code that was relying on this bug. | |
144 | ||
3a5c9134 CBW |
145 | =head1 Deprecations |
146 | ||
147 | XXX Any deprecated features, syntax, modules etc. should be listed here. | |
148 | In particular, deprecated modules should be listed here even if they are | |
149 | listed as an updated module in the L</Modules and Pragmata> section. | |
150 | ||
151 | [ List each deprecation as a =head2 entry ] | |
152 | ||
59773fc7 FC |
153 | =head2 C<?PATTERN?> is deprecated |
154 | ||
155 | C<?PATTERN?> (without the initial m) has been deprecated and now produces | |
156 | a warning. | |
157 | ||
d59a8b3e NC |
158 | =head2 C<sv_compile_2op> is now deprecated |
159 | ||
160 | The C<sv_compile_2op> is now deprecated, and will be removed. Searches suggest | |
161 | that nothing on CPAN is using it, so this should have zero impact. | |
162 | ||
163 | It attempted to provide an API to compile code down to an optree, but failed | |
164 | to bind correctly to lexicals in the enclosing scope. It's not possible to | |
165 | fix this problem within the constraints of its parameters and return value. | |
166 | ||
5609d5f9 FC |
167 | =head2 Tie functions on scalars holding typeglobs |
168 | ||
169 | Calling a tie function (C<tie>, C<tied>, C<untie>) with a scalar argument | |
170 | acts on a file handle if the scalar happens to hold a typeglob. | |
171 | ||
172 | This is a long-standing bug that will be removed in Perl 5.16, as | |
173 | there is currently no way to tie the scalar itself when it holds | |
174 | a typeglob, and no way to untie a scalar that has had a typeglob | |
175 | assigned to it. | |
176 | ||
177 | This bug was fixed in 5.13.7 but, because of the breakage it caused, the | |
178 | fix has been reverted. Now there is a deprecation warning whenever a tie | |
179 | function is used on a handle without an explicit C<*>. | |

503 | C<mg_findext> and C<sv_unmagicext> have been added. |
504 | ||
505 | These new functions allow extension authors to find and remove magic attached to | |
506 | scalars based on both the magic type and the magic virtual table, similar to how | |
507 | C<sv_magicext> attaches magic of a certain type and with a given virtual table | |
508 | to a scalar. This eliminates the need for extensions to walk the list of | |
509 | C<MAGIC> pointers of an C<SV> to find the magic that belongs to them. | |

580 | What has become known as the "Unicode Bug" is resolved in this release. | |
581 | Under C<use feature 'unicode_strings'>, the internal storage format of a | |
582 | string no longer affects the external semantics. There are two known | |
583 | exceptions. User-defined case changing functions, which are planned to | |
584 | be deprecated in 5.14, require utf8-encoded strings to function; and the | |
585 | character C<LATIN SMALL LETTER SHARP S> in regular expression | |
586 | case-insensitive matching has a somewhat different set of bugs depending | |
587 | on the internal storage format. Case-insensitive matching of all | |
588 | characters that have multi-character matches, as this one does, is | |
589 | problematical in Perl. | |

622 | =head1 Reporting Bugs | |
623 | ||
624 | If you find what you think is a bug, you might check the articles | |
625 | recently posted to the comp.lang.perl.misc newsgroup and the perl | |
626 | bug database at http://rt.perl.org/perlbug/ . There may also be | |
627 | information at http://www.perl.org/ , the Perl Home Page. | |
628 | ||
629 | If you believe you have an unreported bug, please run the L<perlbug> | |
630 | program included with your release. Be sure to trim your bug down | |
631 | to a tiny but sufficient test case. Your bug report, along with the | |
632 | output of C<perl -V>, will be sent off to perlbug@perl.org to be | |
633 | analysed by the Perl porting team. | |
634 | ||
635 | If the bug you are reporting has security implications, which make it | |
636 | inappropriate to send to a publicly archived mailing list, then please send | |
637 | it to perl5-security-report@perl.org. This points to a closed subscription | |
638 | unarchived mailing list, which includes all the core committers, who be able | |
639 | to help assess the impact of issues, figure out a resolution, and help | |
640 | co-ordinate the release of patches to mitigate or fix the problem across all | |
641 | platforms on which Perl is supported. Please only use this address for | |
642 | security issues in the Perl core, not for modules independently | |
643 | distributed on CPAN. | |
