16 | L<perl5216delta>, which describes differences between 5.21.5 and 5.21.6. | |

30 | =head2 C<fileno> now works on directory handles |
31 | ||
32 | When the relevant support is available in the operating system, the | |
33 | C<fileno> builtin now works on directory handles, yielding the | |
34 | underlying file descriptor in the same way as for filehandles. On | |
35 | operating systems without such support, C<fileno> on a directory handle | |
36 | continues to return the undefined value, as before, but also sets C<$!> to | |
37 | indicate that the operation is not supported. | |
38 | ||
39 | Currently, this uses either a C<dd_fd> member in the OS C<DIR> | |
40 | structure, or a dirfd(3) function as specified by POSIX.1-2008. | |

aafa61ee | 60 | =head2 C<&> and C<\&> prototypes accepts only subs |
3f22ed99 FC |
61 | |
62 | The C<&> prototype character now accepts only anonymous subs (C<sub {...}>) | |
63 | and things beginning with C<\&>. Formerly it erroneously also allowed | |
64 | C<undef> and references to array, hashes, and lists. [perl #4539] | |
65 | [perl #123062] | |
66 | ||
aafa61ee FC |
67 | The C<\&> prototype was allowing subroutine calls, whereas now it only |
68 | allows subroutines. C<&foo> is permitted. C<&foo()> and C<foo()> are not. | |

71 | =head2 C<use encoding> is now lexical |
72 | ||
73 | The L<encoding> pragma's effect is now limited to lexical scope. This | |
74 | pragma is deprecated, but in the meantime, it could adversely affect | |
75 | unrelated modules that are included in the same program. | |

85 | The following modules will be removed from the core distribution in a |
86 | future release, and will at that time need to be installed from CPAN. | |
87 | Distributions on CPAN which require these modules will need to list them as | |
88 | prerequisites. | |
b450ee68 | 89 | |
4dc623f0 CBW |
90 | The core versions of these modules will now issue C<"deprecated">-category |
91 | warnings to alert you to this fact. To silence these deprecation warnings, | |
92 | install the modules in question from CPAN. | |
b450ee68 | 93 | |
4dc623f0 CBW |
94 | Note that these are (with rare exceptions) fine modules that you are encouraged |
95 | to continue to use. Their disinclusion from core primarily hinges on their | |
96 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
97 | not usually on concerns over their design. | |

110 | =head2 Setting C<${^ENCODING}> to anything but C<undef> |
111 | ||
112 | This variable allows Perl scripts to be written in a non-ASCII, | |
113 | non-UTF-8 encoding. However, it affects all modules globally, leading | |
114 | to wrong answers and segmentation faults. New scripts should be written | |
115 | in UTF-8; old scripts should be converted to UTF-8, which is easily done | |
116 | with the L<encoding> pragma. | |

416 | On Win32, restoring in a child pseudo-process a variable that was |
417 | C<local()>ed in a parent pseudo-process before the C<fork> happened caused | |
418 | memory corruption and a crash in the child pseudo-process (and therefore OS | |
419 | process). | |

423 | Calling C<write> on a format with a C<^**> field could produce a panic |
424 | in sv_chop() if there were insufficient arguments or if the variable | |
425 | used to fill the field was empty. [perl #123245] | |

429 | Non-ASCII lexical sub names (use in error messages) on longer have extra | |

434 | The C<\@> subroutine prototype no longer flattens parenthesized arrays | |
435 | (taking a reference to each element), but takes a reference to the array | |
436 | itself. [perl #47363] | |

440 | A block containing nothing except a C-style C<for> loop could corrupt the | |
441 | stack, causing lists outside the block to lose elements or have elements | |
442 | overwritten. This could happen with C<map { for(...){...} } ...> and with | |
443 | lists containing C<do { for(...){...} }>. [perl #123286] | |

447 | C<scalar()> now propagates lvalue context, so that | |
448 | C<for(scalar($#foo)) { ... }> can modify C<$#foo> through C<$_>. | |

492 | If you find what you think is a bug, you might check the articles recently |
493 | posted to the comp.lang.perl.misc newsgroup and the perl bug database at | |
238894db | 494 | https://rt.perl.org/ . There may also be information at |
7ef8b31d | 495 | http://www.perl.org/ , the Perl Home Page. |

497 | If you believe you have an unreported bug, please run the L<perlbug> program |
498 | included with your release. Be sure to trim your bug down to a tiny but | |
499 | sufficient test case. Your bug report, along with the output of C<perl -V>, | |
500 | will be sent off to perlbug@perl.org to be analysed by the Perl porting team. | |
44691e6f AB |
501 | |
502 | If the bug you are reporting has security implications, which make it | |
e08634c5 SH |
503 | inappropriate to send to a publicly archived mailing list, then please send it |
504 | to perl5-security-report@perl.org. This points to a closed subscription | |
505 | unarchived mailing list, which includes all the core committers, who will be | |
506 | able to help assess the impact of issues, figure out a resolution, and help | |
f9001595 | 507 | co-ordinate the release of patches to mitigate or fix the problem across all |
e08634c5 SH |
508 | platforms on which Perl is supported. Please only use this address for |
509 | security issues in the Perl core, not for modules independently distributed on | |
510 | CPAN. | |
