31 | =head2 New regular expression modifier C</a> |
32 | ||
33 | The C</a> regular expression modifier restricts C<\s> to match precisely | |
34 | the five characters C<[ \f\n\r\t]>, C<\d> to match precisely the 10 | |
35 | characters C<[0-9]>, C<\w> to match precisely the 63 characters | |
36 | C<[A-Za-z0-9_]>, and the Posix (C<[[:posix:]]>) character classes to | |
37 | match only the appropriate ASCII characters. The complements, of | |
38 | course, match everything but; and C<\b> and C<\B> are correspondingly | |
39 | affected. Otherwise, C</a> behaves like the C</u> modifier, in that | |
40 | case-insensitive matching uses Unicode semantics; for example, "k" will | |
41 | match the Unicode C<\N{KELVIN SIGN}> under C</i> matching, and code | |
42 | points in the Latin1 range, above ASCII will have Unicode semantics when | |
43 | it comes to case-insensitive matching. Like its cousins (C</u>, C</l>, | |
44 | and C</d>), and in spite of the terminology, C</a> in 5.14 will not | |
45 | actually be able to be used as a suffix at the end of a regular | |
46 | expression (this restriction is planned to be lifted in 5.16). It must | |
47 | occur either as an infix modifier, such as C<(?a:...)> or (C<(?a)...>, | |
48 | or it can be turned on within the lexical scope of C<use re '/a'>. | |
49 | Turning on C</a> turns off the other "character set" modifiers. | |
50 | ||
086325d8 KW |
51 | =head2 Any unsigned value can be encoded as a character |
52 | ||
6d4f9cf2 | 53 | With this release, Perl is adopting a model that any unsigned value can |
086325d8 KW |
54 | be treated as a code point and encoded internally (as utf8) without |
55 | warnings -- not just the code points that are legal in Unicode. | |
56 | However, unless utf8 warnings have been | |
6d4f9cf2 KW |
57 | explicitly lexically turned off, outputting or performing a |
58 | Unicode-defined operation (such as upper-casing) on such a code point | |
59 | will generate a warning. Attempting to input these using strict rules | |
60 | (such as with the C<:encoding('UTF-8')> layer) will continue to fail. | |
61 | Prior to this release the handling was very inconsistent, and incorrect | |
62 | in places. Also, the Unicode non-characters, some of which previously were | |
63 | erroneously considered illegal in places by Perl, contrary to the Unicode | |
64 | standard, are now always legal internally. But inputting or outputting | |
65 | them will work the same as for the non-legal Unicode code points, as the | |
66 | Unicode standard says they are illegal for "open interchange". | |

68 | =head2 Regular expression debugging output improvement |
69 | ||
70 | Regular expression debugging output (turned on by C<use re 'debug';>) now | |
71 | uses hexadecimal when escaping non-ASCII characters, instead of octal. | |

131 | L<CPAN::Meta::YAML> 0.002 has been added as a dual-life module. It supports a |
132 | subset of YAML sufficient for reading and writing META.yml and MYMETA.yml files | |
133 | included with CPAN distributions or generated by the module installation | |
134 | toolchain. It should not be used for any other general YAML parsing or | |
135 | generation task. | |

140 | small, simple HTTP/1.1 client designed for simple GET requests and file |
141 | mirroring. It has has been added to enable CPAN.pm and CPANPLUS to | |

148 | package and POD information from Perl module files. It is a standalone module |
149 | based on Module::Build::ModuleInfo for use by other module installation | |
150 | toolchain components. Module::Build::ModuleInfo has been deprecated in | |
151 | favor of this module instead. | |

157 | with standardized names (e.g. "Unix" or "Windows"). It has been refactored | |
158 | out of Module::Build and ExtUtils::CBuilder and consolidates such mappings into | |
159 | a single location for easier maintenance. | |

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

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

486 | three static in-line functions for accessing the information: | |

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

636 | regcomp: Disallow multi-char folds in lookbehind | |
637 | ||
638 | The addition of the ANYOFV regnode to treat multi-char folds in a bracketed | |
639 | character class has exposed a bug, in which those classes have long been able | |
640 | to be varying length (due to the multi-char fold), but the compiler wasn't | |
641 | aware of it. Now it is, and hence won't allow those which have multi-char | |
642 | folds to be part of a lookbehind pattern, which requires a constant length. | |
643 | ||
644 | This patch disallows multi-char folds in a lookbehind bracketed character | |
645 | class. | |

767 | regex: Separate nodes for Unicode semantics \s \w | |
768 | ||
769 | This patch converts the \s, \w and complements Unicode semantics to | |
770 | instead of using the flags field of their nodes to instead use separate | |
771 | nodes. This gains some efficiency, especially useful in tight loops and | |
772 | backtracking of regexec.c, and prepares the way for easily adding other | |
773 | semantic variations, such as /a. | |
774 | ||
775 | It refactors the CCC_TRY... macros. I tried to break this piece up into | |
776 | smaller chunks, but found it much easier to get to this in one step. | |
777 | Further patches will do some more refactoring of these. | |
778 | ||
779 | As part of the CCC_TRY macro refactoring, the lines that include the | |
780 | test if (! nextchr) are changed to just look for the end-of-string by | |
781 | position instead of it being NUL. In locales, it could be (however | |
782 | unlikely), that NUL is a real alphabetic, digit, or space character. | |

798 | CH] Change usage of regex/op common to common names | |
799 | ||
800 | This patch changes the core functions to use the common names for the | |
801 | fields that are shared between op.c and regcomp.c, just for consistency | |
802 | of using one name throughout the core for the same thing. | |
803 | ||
804 | A grep of cpan shows that both names are used in various modules; so | |
805 | both names must be retained. | |

811 | Add HTTP::Tiny as a dual-life core module | |
812 | ||
813 | HTTP::Tiny has been added as a dual-life module. It is a very | |
814 | small, simple HTTP/1.1 client designed for simple GET requests and file | |
815 | mirroring. It has has been added to enable CPAN.pm and CPANPLUS to | |
816 | "bootstrap" HTTP access to CPAN using pure Perl without relying on external | |
817 | binaries like F<curl> or F<wget>. | |

829 | Use multi-bit field for regex character set | |
830 | ||
831 | The /d, /l, and /u regex modifiers are mutually exclusive. This patch | |
832 | changes the field that stores the character set to use more than one bit | |
833 | with an enum determining which one. This data structure more | |
834 | closely follows the semantics of their being mutually exclusive, and | |
835 | conserves bits as well, and is better expandable. | |
836 | ||
837 | A small API is added to set and query the bit field. | |

853 | Fix \xa0 matching both [\s] [\S], et.al. | |
854 | ||
855 | This bug stemmed from Latin1 characters not matching any (non-complemented) | |
856 | character class in /d semantics when the target string is no utf8; but having | |
857 | unicode semantics when it isn't. The solution here is to add a special flag. | |
858 | ||
859 | There were several tests that relied on the broken behavior, specifically they | |
860 | tested that \xff isn't a printable word character even in utf8. I changed the | |
861 | deparse test to instead use a non-printable code point, and I changed the ones | |
862 | in re_tests to be TODOs, and will change them back using /a when that is | |
863 | shortly added. | |
864 | ||
865 | ||
866 | SECURITY | |
867 | ||
868 | restrict \p{IsUserDefined} to In\w+ and In\w+ | |
869 | ||
870 | In L<perlunicode/"User-Defined Character Properties">, it says you can | |
871 | create custom properties by defining subroutines whose names begin with | |
872 | "In" or "Is". However, perl doesn't actually enforce that naming | |
873 | restriction, so \p{foo::bar} will call foo::Bar() if it exists. | |
874 | ||
875 | This commit finally enforces this convention. Note that this broke a | |
876 | number of existing tests for properties, since they didn't always use an | |
877 | Is/In prefix. | |

887 | regex: Use ANYOFV | |
888 | ||
889 | This patch restructures the regex ANYOF code to generate ANYOFV nodes instead | |
890 | when there is a possibility that it could match more than one character. Note | |
891 | that this doesn't affect the optimizer, as it essentially ignores things that | |
892 | fit into this category. (But it means that the optimizer will no longer reject | |
893 | these when it shouldn't have.) | |
894 | ||
895 | The handling of the LATIN SHARP s is modified to correspond with this new node | |
896 | type. | |
897 | ||
898 | The initial handling of ANYOFV is placed in regexec.c. More analysis will come | |
899 | on that. But there was significant change to the part that handles matching | |
900 | multi-char strings. This has long been buggy, with it previously comparing a | |
901 | folded-version on one side with a non-folded version on the other. | |
902 | ||
903 | This patch fixes about 60% of the problems that my undelivered test suite gives | |
904 | for multi-char folds. But there are still 17K test failures left, so I'm still | |
905 | not delivering that. The TODOs that this fixes will be cleaned up in a later commit | |

914 | ithread_create() was relying on the stack not moving. Fix this. | |
915 | ||
916 | 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by | |
917 | passing the thread creation arguments as pointers to a block of memory | |
918 | holding SVs. Unfortunately, this inadvertently introduced a subtle bug, | |
919 | because the block of memory is on the Perl stack, which can move as a side | |
920 | effect of being reallocated to extend it. Hence pass in the offset on the | |
921 | stack instead, read the current value of the relevant interpreter's stack | |
922 | at the point of access, and copy all the SVs away before making any further | |
923 | calls which might cause reallocation. | |

934 | ||
935 | Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a | |
936 | platform, they would all return 'Unsupported socket function "gethostent" | |
937 | called', with the analogous results for getnet{byaddr,byname,ent}, | |
938 | getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was | |
939 | introduced by change af51a00e97d5c559 - prior to this, all 12 functions would | |
940 | report their own name when unimplemented. | |

946 | Add warnings for use of problematic code points | |
947 | ||
948 | The non-Unicode code points have no Unicode semantics, so applying operations | |
949 | such as casing on them warns. | |
950 | ||
951 | This patch also includes the changes to test the warnings added by recent | |
952 | commits for handling the surrogates and above-Unicode code points | |

958 | utf8.c(): Default to allow problematic code points | |
959 | ||
960 | Surrogates, non-character code points, and code points that aren't in Unicode | |
961 | are now allowed by default, instead of having to specify a flag to allow them. | |
962 | (Most code did specify those flags anyway.) | |
963 | ||
964 | This affects uvuni_to_utf8_flags(), utf8n_to_uvuni() and various routines that | |
965 | are specialized interfaces to them. | |
966 | ||
967 | Now there is a new set of flags to disallow those code points. Further, all 66 | |
968 | of the non-character code points are known about and handled consistently, | |
969 | instead of just U+FFFF. | |
970 | ||
971 | Code that requires these code points to be forbidden will have to change to use | |
972 | the new flags. I have looked at all the (few) instances in CPAN where these | |
973 | routines are used, and the only one I found that appears to have need to do | |
974 | this, Encode, has already been patched to accommodate this change. Of course, | |
975 | I may have overlooked some subtleties. | |

982 | Generate "Unsupported socket function" stubs using PL_ppaddr. | |
983 | ||
984 | Instead of having each socket op conditionally compile as either the | |
985 | implementation or a DIE() depending on #HAS_SOCKET | |
986 | ||
987 | 1: remove the conditional code from the ops themselves | |
988 | 2: only compile the ops if HAS_SOCKET is defined | |
989 | 3: general conditional code for the intialisation of PL_ppaddr - as appropriate | |
990 | either the ops, or Perl_unimplemented_op | |
991 | 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket | |
992 | ops (ie not the "panic"... message) | |
993 | ||
994 | Whilst this complicates the support code in regen/opcode.pl, it's already a | |

1081 | Make newline on last record explicit. | |
1082 | ||
1083 | On VMS, the last line written to a file will get a trailing newline | |
1084 | willy nilly. This has its advantages insofar as you never get the | |
1085 | "no newline at end of file" warnings from various utilities, but | |
1086 | reality conflicts with expectations when you explicitly test for | |
1087 | the last (or only) line *not* ending with newline, which is what | |
1088 | the recent addtion to ref.t (5e3072707906cc4cb8a364c4cf7c487df0300caa) | |
1089 | was doing. Adding an explicit newline makes everyone happy. | |

1178 | Restore the old description of $[ | |
1179 | ||
1180 | The new entry is a bit too futuristic: assignment to $[ still works | |
1181 | and it is not read-only. | |
1182 | ||
1183 | This does not fully restore the old description, as it contained | |
1184 | grammatical errors and parts of it were not updated when 5.10 changed | |
1185 | the scoping. | |

1191 | [perl #81032] Overhaul Porting/epigraphs.pod | |
1192 | ||
1193 | This patch makes multiple changes to Porting/epigraphs.pod and | |
1194 | pod/perlhist.pod. | |
1195 | ||
1196 | For those that don't know, Porting/epigraphs.pod is a new document that | |
1197 | collects the quotes (chosen by Pumpkins) in perl release announcements. | |
1198 | ||
1199 | The changes are the following. | |
1200 | ||
1201 | 1. Add a link pointing to each release announcement in the mailing | |
1202 | list archives. These are from ysth's list, the source from which | |
1203 | Porting/epigraphs.pod was originally compiled, but they weren't in | |
1204 | Porting/epigraphs.pod so far. | |
1205 | 2. Reorder Porting/epigraphs.pod chronologically, because I believe | |
1206 | that makes more sense -- pod/perlhist.pod is still sorted by version numbers. | |
1207 | 3. Incidentally, some missing releases are added to pod/perlhist.pod too. | |
1208 | 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number. | |
1209 | 5. Add some epigraphs that appear in ysth's list but not in | |
1210 | Porting/epigraphs.pod. | |
1211 | 6. I did some research in perl history before the part that ysth's list | |
1212 | covers, and added older perl announcements I found. This work is not | |
1213 | complete: I stopped somewhere in 2000. | |

1234 | [perl #36347] Object destruction incomplete | |
1235 | ||
1236 | do_clean_objs only looks for objects referenced by RVs, so blessed | |
1237 | array references and lexical variables (and probably other SVs, too) | |
1238 | are not DESTROYed. | |
1239 | ||
1240 | This commit adds a new visit() call to sv_clean_objs, which curses | |
1241 | (DESTROYs and un-blesses, leaving the reference count as it is) any | |
1242 | objects that are still left after do_clean_named_io_objs. The new | |
1243 | do_curse routine (a pointer to which is passeds to visit()) follows | |
1244 | do_clean_named_io_objs’ example and explicitly skips the STDOUT and | |
1245 | STDERR handles, in case destructors need to use them. | |
1246 | ||
1247 | The cursing code, which is now called from two places, is moved out of | |
1248 | sv_clear and put in its own routine. The check that the reference | |
1249 | count is zero does not apply when called from sv_clean_objs, so the | |
1250 | new S_curse routine takes a boolean argument that determines whether | |
1251 | that check should take place. | |

1257 | [perl #73630] Build separate DTrace for miniperl | |
1258 | ||
1259 | As outlined in the RT ticket due to miniperl's dependencies differing to | |
1260 | the final perl binary dtrace -G needs to be called separately for each. | |
1261 | ||
1262 | Build tested on Mac OS X 10.6, Solaris 11 and Scientific Linux with | |
1263 | SystemTap from git. | |
1264 | ||
1265 | (Solaris is the only system I have access to where DTRACE_O actually gets | |
1266 | defined. Neither the dtrace binary on OS X nor SystemTap's dtrace | |
1267 | compatibility layer accept the -G option.) | |

1279 | make <expr> always overload if expr is overloaded | |
1280 | ||
1281 | Due to the way that '<> as glob' was parsed differently from | |
1282 | '<> as filehandle' from 5.6 onwards, something like <$foo[0]> | |
1283 | didn't handle overloading, even where $foo[0] was an overloaded object. | |
1284 | This was contrary to the docs for overload, and meant that <> couldn't | |
1285 | be used as a general overloaded iterator operator. | |

1331 | Better handling of magic methods freeing the SV | |
1332 | ||
1333 | This is a fix for RT #81230 (and more). Currently, mg_get() works around | |
1334 | the case where the called magic (e.g. FETCH) frees the magic SV. It does | |
1335 | this by unconditionally pushing the SV on the tmps stack before invoking | |
1336 | the method. | |
1337 | ||
1338 | There are two issues with this. Firstly, it may artificially extend the | |
1339 | life of the SV. This was the root of the problem with #81230. There, the | |
1340 | DB_File code, under -T, created a tainted tied object. Accessing the | |
1341 | object (within FETCH as it happens), caused mg_get() to be invoked on the | |
1342 | object (due to the taint magic), and thus extend the life of the object. | |
1343 | This then caused c<untie %h if $h{k}> to give the warning | |
1344 | untie attempted while 1 inner references still exist. | |
1345 | This only became noticeable after efaf36747029c85b4d8825318cb4d485a0bb350e, | |
1346 | which stopped wrapping magic method calls in SAVETMPS/FREETMPS. | |
1347 | ||
1348 | The second issue issue that this protection only applies to mg_get(); | |
1349 | functions like mg_set() can still segfault if the SV is deleted. | |
1350 | ||
1351 | This commit fixes both problems as follows: | |
1352 | ||
1353 | First, the protection mechanism is moved out of mg_get() and into | |
1354 | save_magic() / restore_magic(), so that it protects more things. | |
1355 | Secondly, the protection is now: | |
1356 | ||
1357 | * in save_magic(), SvREFCNT_inc() the SV, thus protecting it from being | |
1358 | freed during FETCH (or whatever) | |
1359 | ||
1360 | * in restore_magic(), SvREFCNT_dec() the SV, undoing the protection | |
1361 | without extending the life of the SV, *except* if the refcount is | |
1362 | 1 (ie FETCH tried to free it), then push it on the mortals stack | |
1363 | to extend it life a bit so our callers wont choke on it. | |

1376 | [perl #81016] Document ord("") | |
1377 | ||
1378 | The following patch clarifies what ord("") does in pod/perlfunc.pod. | |
1379 | ||
1380 | From the current documentation, it's not documented what it does, and one | |
1381 | could guess several different things: returns zero, returns undef, returns | |
1382 | zero with a warning, returns undef with a warning, dies. (There's precedent | |
1383 | for dying: some BASIC implementations give an error if you ask for ASC("") | |
1384 | -- here ASC is their equivalent of our ord function.) | |

1397 | Reorganize perlhack.pod | |
1398 | ||
1399 | Following on an IRC conversation, I've attempted to reorganize | |
1400 | perlhack for greater clarity. I have only cut and paste blocks | |
1401 | of text and amended section titles and levels. (I have not addressed | |
1402 | any of the numerous factual issues which remain.) | |
1403 | ||
1404 | The resulting guide should be clearer for those trying to skim the | |
1405 | table of contents to understand what is covered in perlhack and | |
1406 | whether it is worth an in-depth read. | |
1407 | ||
1408 | I see this change as the first step towards future improvements. | |
