31=head2 New regular expression modifier C</a>
32
33The C</a> regular expression modifier restricts C<\s> to match precisely
34the five characters C<[ \f\n\r\t]>, C<\d> to match precisely the 10
35characters C<[0-9]>, C<\w> to match precisely the 63 characters
36C<[A-Za-z0-9_]>, and the Posix (C<[[:posix:]]>) character classes to
37match only the appropriate ASCII characters. The complements, of
38course, match everything but; and C<\b> and C<\B> are correspondingly
39affected. Otherwise, C</a> behaves like the C</u> modifier, in that
40case-insensitive matching uses Unicode semantics; for example, "k" will
41match the Unicode C<\N{KELVIN SIGN}> under C</i> matching, and code
42points in the Latin1 range, above ASCII will have Unicode semantics when
43it comes to case-insensitive matching. Like its cousins (C</u>, C</l>,
44and C</d>), and in spite of the terminology, C</a> in 5.14 will not
45actually be able to be used as a suffix at the end of a regular
46expression (this restriction is planned to be lifted in 5.16). It must
47occur either as an infix modifier, such as C<(?a:...)> or (C<(?a)...>,
48or it can be turned on within the lexical scope of C<use re '/a'>.
49Turning on C</a> turns off the other "character set" modifiers.

51=head2 Any unsigned value can be encoded as a character
52
6d4f9cf2 53With this release, Perl is adopting a model that any unsigned value can
086325d8
KW
54be treated as a code point and encoded internally (as utf8) without
55warnings -- not just the code points that are legal in Unicode.
56However, unless utf8 warnings have been
6d4f9cf2
KW
57explicitly lexically turned off, outputting or performing a
58Unicode-defined operation (such as upper-casing) on such a code point
59will generate a warning. Attempting to input these using strict rules
60(such as with the C<:encoding('UTF-8')> layer) will continue to fail.
61Prior to this release the handling was very inconsistent, and incorrect
62in places. Also, the Unicode non-characters, some of which previously were
63erroneously considered illegal in places by Perl, contrary to the Unicode
64standard, are now always legal internally. But inputting or outputting
65them will work the same as for the non-legal Unicode code points, as the
66Unicode standard says they are illegal for "open interchange".

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

e8a07a12
DG
132subset of YAML sufficient for reading and writing META.yml and MYMETA.yml files
133included with CPAN distributions or generated by the module installation
134toolchain. It should not be used for any other general YAML parsing or

a3ab329f
DG
140small, simple HTTP/1.1 client designed for simple GET requests and file
141mirroring. It has has been added to enable CPAN.pm and CPANPLUS to
142"bootstrap" HTTP access to CPAN using pure Perl without relying on external
143binaries like F<curl> or F<wget>.

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

155L<Perl::OSType> 1.002 has been added as a dual-life module. It maps Perl
156operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic types
157with standardized names (e.g. "Unix" or "Windows"). It has been refactored
158out of Module::Build and ExtUtils::CBuilder and consolidates such mappings into
159a single location for easier maintenance.

466The opcode bodies for C<chop> and C<chomp> and for C<schop> and C<schomp> have
467been merged. The implementation functions C<Perl_do_chop()> and
468C<Perl_do_chomp()>, never part of the public API, have been merged and moved to
469a static function in F<pp.c>. This shrinks the perl binary slightly, and should
470not affect any code outside the core (unless it is relying on the order of side
471effects when C<chomp> is passed a I<list> of values).

475Some of the flags parameters to the uvuni_to_utf8_flags() and
476utf8n_to_uvuni() have changed. This is a result of Perl now allowing
477internal storage and manipulation of code points that are problematic
478in some situations. Hence, the default actions for these functions has
479been complemented to allow these code points. The new flags are
480documented in L<perlapi>. Code that requires the problematic code
481points to be rejected needs to change to use these flags. Some flag
482names are retained for backward source compatibility, though they do
483nothing, as they are now the default. However the flags
484C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and
485C<UNICODE_IS_ILLEGAL> have been removed, as they stem from a
486fundamentally broken model of how the Unicode non-character code points
487should be handled, which is now described in
488L<perlunicode/Non-character code points>. See also L</Selected Bug Fixes>.

519The handling of Unicode non-characters has changed.
520Previously they were mostly considered illegal, except that only one of
521the 66 of them was known about in places. The Unicode standard
522considers them legal, but forbids the "open interchange" of them.
523This is part of the change to allow the internal use of any code point
524(see L</Core Enhancements>). Together, these changes resolve

576If you find what you think is a bug, you might check the articles
577recently posted to the comp.lang.perl.misc newsgroup and the perl
578bug database at http://rt.perl.org/perlbug/ . There may also be
579information at http://www.perl.org/ , the Perl Home Page.
580
581If you believe you have an unreported bug, please run the L<perlbug>
582program included with your release. Be sure to trim your bug down
583to a tiny but sufficient test case. Your bug report, along with the
584output of C<perl -V>, will be sent off to perlbug@perl.org to be
585analysed by the Perl porting team.
586
587If the bug you are reporting has security implications, which make it
588inappropriate to send to a publicly archived mailing list, then please send
589it to perl5-security-report@perl.org. This points to a closed subscription
590unarchived mailing list, which includes all the core committers, who be able
591to help assess the impact of issues, figure out a resolution, and help
592co-ordinate the release of patches to mitigate or fix the problem across all
593platforms on which Perl is supported. Please only use this address for
594security issues in the Perl core, not for modules independently
595distributed on CPAN.

659 regcomp: Disallow multi-char folds in lookbehind
660
661 The addition of the ANYOFV regnode to treat multi-char folds in a bracketed
662 character class has exposed a bug, in which those classes have long been able
663 to be varying length (due to the multi-char fold), but the compiler wasn't
664 aware of it. Now it is, and hence won't allow those which have multi-char
665 folds to be part of a lookbehind pattern, which requires a constant length.
666
667 This patch disallows multi-char folds in a lookbehind bracketed character
668 class.

790 regex: Separate nodes for Unicode semantics \s \w
791
792 This patch converts the \s, \w and complements Unicode semantics to
793 instead of using the flags field of their nodes to instead use separate
794 nodes. This gains some efficiency, especially useful in tight loops and
795 backtracking of regexec.c, and prepares the way for easily adding other
796 semantic variations, such as /a.
797
798 It refactors the CCC_TRY... macros. I tried to break this piece up into
799 smaller chunks, but found it much easier to get to this in one step.
800 Further patches will do some more refactoring of these.
801
802 As part of the CCC_TRY macro refactoring, the lines that include the
803 test if (! nextchr) are changed to just look for the end-of-string by
804 position instead of it being NUL. In locales, it could be (however
805 unlikely), that NUL is a real alphabetic, digit, or space character.

823 This patch changes the core functions to use the common names for the
824 fields that are shared between op.c and regcomp.c, just for consistency
825 of using one name throughout the core for the same thing.

852 Use multi-bit field for regex character set
853
854 The /d, /l, and /u regex modifiers are mutually exclusive. This patch
855 changes the field that stores the character set to use more than one bit
856 with an enum determining which one. This data structure more
857 closely follows the semantics of their being mutually exclusive, and
858 conserves bits as well, and is better expandable.
859
860 A small API is added to set and query the bit field.

876 Fix \xa0 matching both [\s] [\S], et.al.
877
878 This bug stemmed from Latin1 characters not matching any (non-complemented)
879 character class in /d semantics when the target string is no utf8; but having
880 unicode semantics when it isn't. The solution here is to add a special flag.
881
882 There were several tests that relied on the broken behavior, specifically they
883 tested that \xff isn't a printable word character even in utf8. I changed the
884 deparse test to instead use a non-printable code point, and I changed the ones
885 in re_tests to be TODOs, and will change them back using /a when that is
886 shortly added.

891 restrict \p{IsUserDefined} to In\w+ and In\w+
892
893 In L<perlunicode/"User-Defined Character Properties">, it says you can
894 create custom properties by defining subroutines whose names begin with
895 "In" or "Is". However, perl doesn't actually enforce that naming
896 restriction, so \p{foo::bar} will call foo::Bar() if it exists.
897
898 This commit finally enforces this convention. Note that this broke a
899 number of existing tests for properties, since they didn't always use an
900 Is/In prefix.

910 regex: Use ANYOFV
911
912 This patch restructures the regex ANYOF code to generate ANYOFV nodes instead
913 when there is a possibility that it could match more than one character. Note
914 that this doesn't affect the optimizer, as it essentially ignores things that
915 fit into this category. (But it means that the optimizer will no longer reject
916 these when it shouldn't have.)
917
918 The handling of the LATIN SHARP s is modified to correspond with this new node
919 type.
920
921 The initial handling of ANYOFV is placed in regexec.c. More analysis will come
922 on that. But there was significant change to the part that handles matching
923 multi-char strings. This has long been buggy, with it previously comparing a
924 folded-version on one side with a non-folded version on the other.
925
926 This patch fixes about 60% of the problems that my undelivered test suite gives
927 for multi-char folds. But there are still 17K test failures left, so I'm still
928 not delivering that. The TODOs that this fixes will be cleaned up in a later commit

937 ithread_create() was relying on the stack not moving. Fix this.
938
939 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
940 passing the thread creation arguments as pointers to a block of memory
941 holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
942 because the block of memory is on the Perl stack, which can move as a side
943 effect of being reallocated to extend it. Hence pass in the offset on the
944 stack instead, read the current value of the relevant interpreter's stack
945 at the point of access, and copy all the SVs away before making any further
946 calls which might cause reallocation.

955DIAGNOSTICS
956 Correct the "unimplemented" message for get{host,net,proto,serv}ent aliases.
957
958 Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a
959 platform, they would all return 'Unsupported socket function "gethostent"
960 called', with the analogous results for getnet{byaddr,byname,ent},
961 getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was
962 introduced by change af51a00e97d5c559 - prior to this, all 12 functions would
963 report their own name when unimplemented.

969 Add warnings for use of problematic code points
970
971 The non-Unicode code points have no Unicode semantics, so applying operations
972 such as casing on them warns.

975 commits for handling the surrogates and above-Unicode code points

981 utf8.c(): Default to allow problematic code points
982
983 Surrogates, non-character code points, and code points that aren't in Unicode
984 are now allowed by default, instead of having to specify a flag to allow them.
985 (Most code did specify those flags anyway.)
986
987 This affects uvuni_to_utf8_flags(), utf8n_to_uvuni() and various routines that
988 are specialized interfaces to them.
989
990 Now there is a new set of flags to disallow those code points. Further, all 66
991 of the non-character code points are known about and handled consistently,
992 instead of just U+FFFF.
993
994 Code that requires these code points to be forbidden will have to change to use
995 the new flags. I have looked at all the (few) instances in CPAN where these
996 routines are used, and the only one I found that appears to have need to do
997 this, Encode, has already been patched to accommodate this change. Of course,
998 I may have overlooked some subtleties.

1005 Generate "Unsupported socket function" stubs using PL_ppaddr.
1006
1007 Instead of having each socket op conditionally compile as either the
1008 implementation or a DIE() depending on #HAS_SOCKET
1009
1010 1: remove the conditional code from the ops themselves
1011 2: only compile the ops if HAS_SOCKET is defined
1012 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
1013 either the ops, or Perl_unimplemented_op
1014 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
1015 ops (ie not the "panic"... message)
1016
1017 Whilst this complicates the support code in regen/opcode.pl, it's already a

1104 Make newline on last record explicit.
1105
1106 On VMS, the last line written to a file will get a trailing newline
1107 willy nilly. This has its advantages insofar as you never get the
1108 "no newline at end of file" warnings from various utilities, but
1109 reality conflicts with expectations when you explicitly test for
1110 the last (or only) line *not* ending with newline, which is what
1111 the recent addtion to ref.t (5e3072707906cc4cb8a364c4cf7c487df0300caa)
1112 was doing. Adding an explicit newline makes everyone happy.

1123 refactored out of Module::Build and ExtUtils::CBuilder and consolidates
1124 such mappings into a single location for easier maintenance.

1214 [perl #81032] Overhaul Porting/epigraphs.pod
1215
1216 This patch makes multiple changes to Porting/epigraphs.pod and
1217 pod/perlhist.pod.
1218
1219 For those that don't know, Porting/epigraphs.pod is a new document that
1220 collects the quotes (chosen by Pumpkins) in perl release announcements.
1221
1222 The changes are the following.
1223
1224 1. Add a link pointing to each release announcement in the mailing
1225 list archives. These are from ysth's list, the source from which
1226 Porting/epigraphs.pod was originally compiled, but they weren't in
1227 Porting/epigraphs.pod so far.
1228 2. Reorder Porting/epigraphs.pod chronologically, because I believe
1229 that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
1230 3. Incidentally, some missing releases are added to pod/perlhist.pod too.
1231 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
1232 5. Add some epigraphs that appear in ysth's list but not in
1233 Porting/epigraphs.pod.
1234 6. I did some research in perl history before the part that ysth's list
1235 covers, and added older perl announcements I found. This work is not
1236 complete: I stopped somewhere in 2000.

1257 [perl #36347] Object destruction incomplete
1258
1259 do_clean_objs only looks for objects referenced by RVs, so blessed
1260 array references and lexical variables (and probably other SVs, too)
1261 are not DESTROYed.
1262
1263 This commit adds a new visit() call to sv_clean_objs, which curses
1264 (DESTROYs and un-blesses, leaving the reference count as it is) any
1265 objects that are still left after do_clean_named_io_objs. The new
1266 do_curse routine (a pointer to which is passeds to visit()) follows
1267 do_clean_named_io_objs’ example and explicitly skips the STDOUT and
1268 STDERR handles, in case destructors need to use them.
1269
1270 The cursing code, which is now called from two places, is moved out of
1271 sv_clear and put in its own routine. The check that the reference
1272 count is zero does not apply when called from sv_clean_objs, so the
1273 new S_curse routine takes a boolean argument that determines whether
1274 that check should take place.

1300 didn't handle overloading, even where $foo[0] was an overloaded object.
