38 | =head2 Unicode version |
39 | |
40 | Perl is shipped with the latest Unicode version, 5.2, October 2009. See |
41 | L<http://www.unicode.org/versions/Unicode5.2.0> for details about this release |
db2ed548 |
42 | of Unicode. See L<perlunicode> for instructions on installing and using |
43 | older versions of Unicode. |
37e2e78e |
44 | |
8d814567 |
45 | =head2 Unicode properties |
46 | |
47 | Perl can now handle every Unicode character property. A new pod, |
48 | L<perluniprops>, lists all available non-Unihan character properties. By |
49 | default the Unihan properties and certain others (deprecated and Unicode |
50 | internal-only ones) are not exposed. See below for more details on |
51 | these; there is also a section in the pod listing them, and why they are |
52 | not exposed. |
53 | |
54 | Perl now fully supports the Unicode compound-style of using C<=> and C<:> |
55 | in writing regular expressions: C<\p{property=value}> and |
56 | C<\p{property:value}> (both of which mean the same thing). |
57 | |
db2ed548 |
58 | Perl now fully supports the Unicode loose matching rules for text |
8d814567 |
59 | between the braces in C<\p{...}> constructs. In addition, Perl also allows |
60 | underscores between digits of numbers. |
61 | |
62 | All the Unicode-defined synonyms for properties and property values are |
63 | now accepted. |
64 | |
37e2e78e |
65 | C<qr/\X/>, which matches a Unicode logical character, has been expanded to work |
66 | better with various Asian languages. It now is defined as an C<extended |
67 | grapheme cluster>. (See L<http://www.unicode.org/reports/tr29/>). One change |
68 | due to this is that C<\X> will match the whole sequence C<S<CR LF>>. Another |
69 | change is that C<\X> will match an isolated mark. Marks generally come after a |
70 | base character, but it is possible in Unicode to have them in isolation, and |
71 | C<\X> will now handle that case. Otherwise, this change should be transparent |
db2ed548 |
72 | for non-affected languages. |
37e2e78e |
73 | |
8d814567 |
74 | C<\p{...}> matches using the Canonical_Combining_Class property were |
75 | completely broken in previous Perls. This is now fixed. |
76 | |
77 | In previous Perls, the Unicode Decomposition_Type=Compat property and a |
78 | Perl extension had the same name, which led to neither matching all the |
79 | correct values (with more than 100 mistakes in one, and several thousand |
80 | in the other). The Perl extension has now been renamed to be |
81 | Decomposition_Type=Noncanonical (short: dt=noncanon). It has the same |
82 | meaning as was previously intended, namely the union of all the |
83 | non-canonical Decomposition types, with Unicode Compat being just one of |
84 | those. |
85 | |
86 | C<\p{Uppercase}> and C<\p{Lowercase}> have been brought into line with the |
87 | Unicode definitions. This means they each match a few more characters |
88 | than previously. |
89 | |
90 | C<\p{Cntrl}> now matches the same characters as C<\p{Control}>. This means it |
91 | no longer will match Private Use (gc=co), Surrogates (gc=cs), nor Format |
92 | (gc=cf) code points. The Format code points represent the biggest |
93 | possible problem. All but 36 of them are either officially deprecated |
94 | or strongly discouraged from being used. Of those 36, likely the most |
95 | widely used are the soft hyphen (U+00AD), and BOM, ZWSP, ZWNJ, WJ, and |
96 | similar, plus Bi-directional controls. |
97 | |
98 | C<\p{Alpha}> now matches the same characters as C<\p{Alphabetic}>. The Perl |
99 | definition included a number of things that aren't really alpha (all |
100 | marks), while omitting many that were. The Unicode definition is |
101 | clearly better, so we are switching to it. As a direct consequence, the |
102 | definitions of C<\p{Alnum}> and C<\p{Word}> which depend on Alpha also change. |
103 | |
104 | C<\p{Word}> also now doesn't match certain characters it wasn't supposed |
105 | to, such as fractions. |
106 | |
107 | C<\p{Print}> no longer matches the line control characters: tab, lf, cr, |
108 | ff, vt, and nel. This brings it in line with the documentation. |
109 | |
db2ed548 |
110 | C<\p{Decomposition_Type=Canonical}> now includes the Hangul syllables |
8d814567 |
111 | |
112 | The Numeric type property has been extended to include the Unihan |
113 | characters. |
114 | |
115 | There is a new Perl extension, the 'Present_In', or simply 'In' |
116 | property. This is an extension of the Unicode Age property, but |
117 | C<\p{In=5.0}> matches any code point whose usage has been determined as of |
118 | Unicode version 5.0. The C<\p{Age=5.0}> only matches code points added in 5.0. |
119 | |
120 | A number of properties did not have the correct values for unassigned |
121 | code points. This is now fixed. The affected properties are |
122 | Bidi_Class, East_Asian_Width, Joining_Type, Decomposition_Type, |
123 | Hangul_Syllable_Type, Numeric_Type, and Line_Break. |
124 | |
125 | The Default_Ignorable_Code_Point, ID_Continue, and ID_Start properties |
126 | have been updated to their current definitions. |
127 | |
128 | Certain properties that are supposed to be Unicode internal-only were |
129 | erroneously exposed by previous Perls. Use of these in regular |
130 | expressions will now generate a deprecated warning message, if those |
131 | warnings are enabled. The properties are: Other_Alphabetic, |
132 | Other_Default_Ignorable_Code_Point, Other_Grapheme_Extend, |
133 | Other_ID_Continue, Other_ID_Start, Other_Lowercase, Other_Math, and |
134 | Other_Uppercase. |
135 | |
8d814567 |
136 | An installation can now fairly easily change which Unicode properties |
137 | Perl understands. As mentioned above, certain properties are by default |
138 | turned off. These include all the Unihan properties (which should be |
139 | accessible via the CPAN module Unicode::Unihan) and any deprecated or |
140 | Unicode internal-only property that Perl has never exposed. |
141 | |
db2ed548 |
142 | XXX what does "files in the To directory" mean? -- dagolden, 2009-12-20 |
143 | |
8d814567 |
144 | The files in the To directory are now more clearly marked as being |
145 | stable, directly usable by applications. New hash entries in them give |
146 | the format of the normal entries which allows for easier machine |
147 | parsing. Perl can generate files in this directory for any property, |
148 | though most are suppressed. An installation can choose to change which |
149 | get written. Instructions are in L<perluniprops>. |

349 | Always add a manifest resource to C<perl.exe> to specify the <trustInfo> |
350 | settings for Windows Vista and later. Without this setting Windows |
351 | will treat C<perl.exe> as a legacy application and apply various |
352 | heuristics like redirecting access to protected file system areas |
353 | (like the "Program Files" folder) to the users "VirtualStore" |
354 | instead of generating a proper "permission denied" error. |
355 | |
356 | For VC8 and VC9 this manifest setting is automatically generated by |
357 | the compiler/linker (together with the binding information for their |
358 | respective runtime libraries); for all other compilers we need to |
359 | embed the manifest resource explicitly in the external resource file. |

401 | Ensure that pp_qr returns a new regexp SV each time. Resolves RT #69852. |
402 | |
403 | Instead of returning a(nother) reference to the (pre-compiled) regexp in the |
404 | optree, use reg_temp_copy() to create a copy of it, and return a reference to |
405 | that. This resolves issues about Regexp::DESTROY not being called in a timely |
406 | fashion (the original bug tracked by RT #69852), as well as bugs related to |
407 | blessing regexps, and of assigning to regexps, as described in correspondence |
408 | added to the ticket. |
409 | |
410 | It transpires that we also need to undo the SvPVX() sharing when ithreads |
411 | cloning a Regexp SV, because mother_re is set to NULL, instead of a cloned |
412 | copy of the mother_re. This change might fix bugs with regexps and threads in |
413 | certain other situations, but as yet neither tests nor bug reports have |

537 | =head1 Reporting Bugs |
538 | |
539 | If you find what you think is a bug, you might check the articles |
540 | recently posted to the comp.lang.perl.misc newsgroup and the perl |
541 | bug database at http://rt.perl.org/perlbug/ . There may also be |
542 | information at http://www.perl.org/ , the Perl Home Page. |
543 | |
544 | If you believe you have an unreported bug, please run the B<perlbug> |
545 | program included with your release. Be sure to trim your bug down |
546 | to a tiny but sufficient test case. Your bug report, along with the |
547 | output of C<perl -V>, will be sent off to perlbug@perl.org to be |
548 | analysed by the Perl porting team. |
549 | |
550 | If the bug you are reporting has security implications, which make it |
551 | inappropriate to send to a publicly archived mailing list, then please send |
552 | it to perl5-security-report@perl.org. This points to a closed subscription |
553 | unarchived mailing list, which includes all the core committers, who be able |
554 | to help assess the impact of issues, figure out a resolution, and help |
555 | co-ordinate the release of patches to mitigate or fix the problem across all |
556 | platforms on which Perl is supported. Please only use this address for |
557 | security issues in the Perl core, not for modules independently |
558 | distributed on CPAN. |

585 | Export PL_curinterp symbol for MULTIPLICITY without USE_ITHREADS |
db2ed548 |
586 | |
7ef88767 |
587 | This is necessary for XS extensions that define PERL_CORE. In that |
588 | situation PERL_GET_CONTEXT will resolve to PL_curinterp, which is |
589 | normally not exported (extensions call Perl_Gcurinterp_ptr() to get a |
590 | pointer to PL_curinterp instead). With USE_ITHREADS defined |
591 | PERL_GET_CONTEXT will expand to Perl_get_context() even inside the |
592 | core because the context needs to be fetched from threadlocal storage. |

623 | commit 69dc4b30f4725ad5f212d45d3c856ac1caaacf17 |

625 | Date: Mon Dec 14 12:19:35 2009 +0100 |
626 | |
627 | [perl #70764] $' fails to initialized for pre-compiled regular expression matches |
db2ed548 |
628 | |
7ef88767 |
629 | The match vars are associated with the regexp that last matched |
630 | successfully. In the case of $str =~ $qr or /$qr/, since the $qr could |
631 | be used in multiple scopes that need their own sets of match vars, the |
632 | $qr is cloned by Perl_reg_temp_copy as of change 30677/28d8d7f. This |
633 | happens in pp_regcomp before pp_match has stringified the LHS, hence the |
634 | bug. In short, /$gror/ is not equivalent to |
635 | ($which = !$which) ? /$gror/ : /$gror/, which is weird. |

658 | [perl #71076] sort with active sub (5.10 regression) |
db2ed548 |
659 | |
7ef88767 |
660 | One of the tests in sort.t causes a bus error (or sometimes â\80\98Undefined |
661 | subroutine calledâ\80\99) if run multiple times. This is because sort |
662 | decreases the refcount of an active sub used as a comparison routine. |

681 | Cleanup all scopes before exiting a pseudo-forked process. |
db2ed548 |
682 | |
7ef88767 |
683 | perl_destruct() contains an assertion that the scope stack |
684 | is empty. The remaining scopes are due to fork() being |
685 | called from within a BEGIN block. |
