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.

465The opcode bodies for C<chop> and C<chomp> and for C<schop> and C<schomp> have
466been merged. The implementation functions C<Perl_do_chop()> and
467C<Perl_do_chomp()>, never part of the public API, have been merged and moved to
468a static function in F<pp.c>. This shrinks the perl binary slightly, and should
469not affect any code outside the core (unless it is relying on the order of side
470effects when C<chomp> is passed a I<list> of values).

474Some of the flags parameters to the uvuni_to_utf8_flags() and
475utf8n_to_uvuni() have changed. This is a result of Perl now allowing
476internal storage and manipulation of code points that are problematic
477in some situations. Hence, the default actions for these functions has
478been complemented to allow these code points. The new flags are
479documented in L<perlapi>. Code that requires the problematic code
480points to be rejected needs to change to use these flags. Some flag
481names are retained for backward source compatibility, though they do
482nothing, as they are now the default. However the flags
483C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and
484C<UNICODE_IS_ILLEGAL> have been removed, as they stem from a
485fundamentally broken model of how the Unicode non-character code points
486should be handled, which is now described in
487L<perlunicode/Non-character code points>. See also L</Selected Bug Fixes>.

518The handling of Unicode non-characters has changed.
519Previously they were mostly considered illegal, except that only one of
520the 66 of them was known about in places. The Unicode standard
521considers them legal, but forbids the "open interchange" of them.
522This is part of the change to allow the internal use of any code point
523(see L</Core Enhancements>). Together, these changes resolve

575If you find what you think is a bug, you might check the articles
576recently posted to the comp.lang.perl.misc newsgroup and the perl
577bug database at http://rt.perl.org/perlbug/ . There may also be
578information at http://www.perl.org/ , the Perl Home Page.
579
580If you believe you have an unreported bug, please run the L<perlbug>
581program included with your release. Be sure to trim your bug down
582to a tiny but sufficient test case. Your bug report, along with the
583output of C<perl -V>, will be sent off to perlbug@perl.org to be
584analysed by the Perl porting team.
585
586If the bug you are reporting has security implications, which make it
587inappropriate to send to a publicly archived mailing list, then please send
588it to perl5-security-report@perl.org. This points to a closed subscription
589unarchived mailing list, which includes all the core committers, who be able
590to help assess the impact of issues, figure out a resolution, and help
591co-ordinate the release of patches to mitigate or fix the problem across all
592platforms on which Perl is supported. Please only use this address for
593security issues in the Perl core, not for modules independently
594distributed on CPAN.

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

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

821
822 This patch changes the core functions to use the common names for the
823 fields that are shared between op.c and regcomp.c, just for consistency
824 of using one name throughout the core for the same thing.

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

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

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

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

935
936 ithread_create() was relying on the stack not moving. Fix this.
937
938 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
939 passing the thread creation arguments as pointers to a block of memory
940 holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
941 because the block of memory is on the Perl stack, which can move as a side
942 effect of being reallocated to extend it. Hence pass in the offset on the
943 stack instead, read the current value of the relevant interpreter's stack
944 at the point of access, and copy all the SVs away before making any further
945 calls which might cause reallocation.

954DIAGNOSTICS
955 Correct the "unimplemented" message for get{host,net,proto,serv}ent aliases.
956
957 Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a
958 platform, they would all return 'Unsupported socket function "gethostent"
959 called', with the analogous results for getnet{byaddr,byname,ent},
960 getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was
961 introduced by change af51a00e97d5c559 - prior to this, all 12 functions would
962 report their own name when unimplemented.

968 Add warnings for use of problematic code points
969
970 The non-Unicode code points have no Unicode semantics, so applying operations
971 such as casing on them warns.
972
973 This patch also includes the changes to test the warnings added by recent
974 commits for handling the surrogates and above-Unicode code points

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

1003
1004 Generate "Unsupported socket function" stubs using PL_ppaddr.
1005
1006 Instead of having each socket op conditionally compile as either the
1007 implementation or a DIE() depending on #HAS_SOCKET
1008
1009 1: remove the conditional code from the ops themselves
1010 2: only compile the ops if HAS_SOCKET is defined
1011 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
1012 either the ops, or Perl_unimplemented_op
1013 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
1014 ops (ie not the "panic"... message)
1015
1016 Whilst this complicates the support code in regen/opcode.pl, it's already a
1017 net saving of 5 lines in the C code.

1026 locations that relied on them.
1027
1028 regen/opcode.pl now generates prototypes for the PP functions directly, into
1029 pp_proto.h. It no longer writes pp.sym, and regen/embed.pl no longer reads
1030 this, removing the only ordering dependency in the regen scripts. opcode.pl
1031 is now responsible for prototypes for pp_* functions. (embed.pl remains
1032 responsible for ck_* functions, reading from regen/opcodes)

1087 This commit adds Module::Metadata 1.000002 as a dual-life module. It

1091 has been deprecated in favor of this module instead.

1103 Make newline on last record explicit.
1104
1105 On VMS, the last line written to a file will get a trailing newline
1106 willy nilly. This has its advantages insofar as you never get the
1107 "no newline at end of file" warnings from various utilities, but
1108 reality conflicts with expectations when you explicitly test for
1109 the last (or only) line *not* ending with newline, which is what
1110 the recent addtion to ref.t (5e3072707906cc4cb8a364c4cf7c487df0300caa)
1111 was doing. Adding an explicit newline makes everyone happy.

1118
1119 This commit adds Perl::OSType 1.002 as a dual-life module. It maps Perl
1120 operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic
1121 types with standardized names (e.g. "Unix" or "Windows"). It has been
1122 refactored out of Module::Build and ExtUtils::CBuilder and consolidates
1123 such mappings into a single location for easier maintenance.

1213 [perl #81032] Overhaul Porting/epigraphs.pod
1214
1215 This patch makes multiple changes to Porting/epigraphs.pod and
1216 pod/perlhist.pod.
1217
1218 For those that don't know, Porting/epigraphs.pod is a new document that
1219 collects the quotes (chosen by Pumpkins) in perl release announcements.
1220
1221 The changes are the following.
1222
1223 1. Add a link pointing to each release announcement in the mailing
1224 list archives. These are from ysth's list, the source from which
1225 Porting/epigraphs.pod was originally compiled, but they weren't in
1226 Porting/epigraphs.pod so far.
1227 2. Reorder Porting/epigraphs.pod chronologically, because I believe
1228 that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
1229 3. Incidentally, some missing releases are added to pod/perlhist.pod too.
1230 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
1231 5. Add some epigraphs that appear in ysth's list but not in
1232 Porting/epigraphs.pod.
1233 6. I did some research in perl history before the part that ysth's list
1234 covers, and added older perl announcements I found. This work is not
1235 complete: I stopped somewhere in 2000.

1256 [perl #36347] Object destruction incomplete
1257
1258 do_clean_objs only looks for objects referenced by RVs, so blessed
1259 array references and lexical variables (and probably other SVs, too)
1260 are not DESTROYed.
1261
1262 This commit adds a new visit() call to sv_clean_objs, which curses
1263 (DESTROYs and un-blesses, leaving the reference count as it is) any
1264 objects that are still left after do_clean_named_io_objs. The new
1265 do_curse routine (a pointer to which is passeds to visit()) follows
1266 do_clean_named_io_objs’ example and explicitly skips the STDOUT and
1267 STDERR handles, in case destructors need to use them.
1268
1269 The cursing code, which is now called from two places, is moved out of
1270 sv_clear and put in its own routine. The check that the reference
1271 count is zero does not apply when called from sv_clean_objs, so the
1272 new S_curse routine takes a boolean argument that determines whether
1273 that check should take place.

1295 make <expr> always overload if expr is overloaded
1296
1297 Due to the way that '<> as glob' was parsed differently from
1298 '<> as filehandle' from 5.6 onwards, something like <$foo[0]>
1299 didn't handle overloading, even where $foo[0] was an overloaded object.
1300 This was contrary to the docs for overload, and meant that <> couldn't
1301 be used as a general overloaded iterator operator.

1328 Reorganize perlhack.pod
1329
1330 Following on an IRC conversation, I've attempted to reorganize
1331 perlhack for greater clarity. I have only cut and paste blocks
1332 of text and amended section titles and levels. (I have not addressed
1333 any of the numerous factual issues which remain.)
1334
1335 The resulting guide should be clearer for those trying to skim the
1336 table of contents to understand what is covered in perlhack and
1337 whether it is worth an in-depth read.
1338
1339 I see this change as the first step towards future improvements.
