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

567
568If you find what you think is a bug, you might check the articles
569recently posted to the comp.lang.perl.misc newsgroup and the perl
570bug database at http://rt.perl.org/perlbug/ . There may also be
571information at http://www.perl.org/ , the Perl Home Page.
572
573If you believe you have an unreported bug, please run the L<perlbug>
574program included with your release. Be sure to trim your bug down
575to a tiny but sufficient test case. Your bug report, along with the
576output of C<perl -V>, will be sent off to perlbug@perl.org to be
577analysed by the Perl porting team.
578
579If the bug you are reporting has security implications, which make it
580inappropriate to send to a publicly archived mailing list, then please send
581it to perl5-security-report@perl.org. This points to a closed subscription
582unarchived mailing list, which includes all the core committers, who be able
583to help assess the impact of issues, figure out a resolution, and help
584co-ordinate the release of patches to mitigate or fix the problem across all
585platforms on which Perl is supported. Please only use this address for
586security issues in the Perl core, not for modules independently
587distributed on CPAN.

651 regcomp: Disallow multi-char folds in lookbehind
652
653 The addition of the ANYOFV regnode to treat multi-char folds in a bracketed
654 character class has exposed a bug, in which those classes have long been able
655 to be varying length (due to the multi-char fold), but the compiler wasn't
656 aware of it. Now it is, and hence won't allow those which have multi-char
657 folds to be part of a lookbehind pattern, which requires a constant length.
658
659 This patch disallows multi-char folds in a lookbehind bracketed character
660 class.

782 regex: Separate nodes for Unicode semantics \s \w
783
784 This patch converts the \s, \w and complements Unicode semantics to
785 instead of using the flags field of their nodes to instead use separate
786 nodes. This gains some efficiency, especially useful in tight loops and
787 backtracking of regexec.c, and prepares the way for easily adding other
788 semantic variations, such as /a.
789
790 It refactors the CCC_TRY... macros. I tried to break this piece up into
791 smaller chunks, but found it much easier to get to this in one step.
792 Further patches will do some more refactoring of these.
793
794 As part of the CCC_TRY macro refactoring, the lines that include the
795 test if (! nextchr) are changed to just look for the end-of-string by
796 position instead of it being NUL. In locales, it could be (however
797 unlikely), that NUL is a real alphabetic, digit, or space character.

815 This patch changes the core functions to use the common names for the

817 of using one name throughout the core for the same thing.

844 Use multi-bit field for regex character set
845
846 The /d, /l, and /u regex modifiers are mutually exclusive. This patch
847 changes the field that stores the character set to use more than one bit
848 with an enum determining which one. This data structure more
849 closely follows the semantics of their being mutually exclusive, and
850 conserves bits as well, and is better expandable.
851
852 A small API is added to set and query the bit field.

868 Fix \xa0 matching both [\s] [\S], et.al.
869
870 This bug stemmed from Latin1 characters not matching any (non-complemented)
871 character class in /d semantics when the target string is no utf8; but having
872 unicode semantics when it isn't. The solution here is to add a special flag.
873
874 There were several tests that relied on the broken behavior, specifically they
875 tested that \xff isn't a printable word character even in utf8. I changed the
876 deparse test to instead use a non-printable code point, and I changed the ones
877 in re_tests to be TODOs, and will change them back using /a when that is
878 shortly added.

883 restrict \p{IsUserDefined} to In\w+ and In\w+
884
885 In L<perlunicode/"User-Defined Character Properties">, it says you can
886 create custom properties by defining subroutines whose names begin with
887 "In" or "Is". However, perl doesn't actually enforce that naming
888 restriction, so \p{foo::bar} will call foo::Bar() if it exists.
889
890 This commit finally enforces this convention. Note that this broke a
891 number of existing tests for properties, since they didn't always use an
892 Is/In prefix.

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

929 ithread_create() was relying on the stack not moving. Fix this.
930
931 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
932 passing the thread creation arguments as pointers to a block of memory
933 holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
934 because the block of memory is on the Perl stack, which can move as a side
935 effect of being reallocated to extend it. Hence pass in the offset on the
936 stack instead, read the current value of the relevant interpreter's stack
937 at the point of access, and copy all the SVs away before making any further
938 calls which might cause reallocation.

947DIAGNOSTICS
948 Correct the "unimplemented" message for get{host,net,proto,serv}ent aliases.
949
950 Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a
951 platform, they would all return 'Unsupported socket function "gethostent"
952 called', with the analogous results for getnet{byaddr,byname,ent},
953 getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was
954 introduced by change af51a00e97d5c559 - prior to this, all 12 functions would
955 report their own name when unimplemented.

961 Add warnings for use of problematic code points
962
963 The non-Unicode code points have no Unicode semantics, so applying operations

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

973 utf8.c(): Default to allow problematic code points
974
975 Surrogates, non-character code points, and code points that aren't in Unicode
976 are now allowed by default, instead of having to specify a flag to allow them.
977 (Most code did specify those flags anyway.)
978
979 This affects uvuni_to_utf8_flags(), utf8n_to_uvuni() and various routines that
980 are specialized interfaces to them.
981
982 Now there is a new set of flags to disallow those code points. Further, all 66
983 of the non-character code points are known about and handled consistently,
984 instead of just U+FFFF.
985
986 Code that requires these code points to be forbidden will have to change to use
987 the new flags. I have looked at all the (few) instances in CPAN where these
988 routines are used, and the only one I found that appears to have need to do
989 this, Encode, has already been patched to accommodate this change. Of course,
990 I may have overlooked some subtleties.

997 Generate "Unsupported socket function" stubs using PL_ppaddr.
998
999 Instead of having each socket op conditionally compile as either the
1000 implementation or a DIE() depending on #HAS_SOCKET
1001
1002 1: remove the conditional code from the ops themselves
1003 2: only compile the ops if HAS_SOCKET is defined
1004 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
1005 either the ops, or Perl_unimplemented_op
1006 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
1007 ops (ie not the "panic"... message)

1009 Whilst this complicates the support code in regen/opcode.pl, it's already a

1096 Make newline on last record explicit.
1097
1098 On VMS, the last line written to a file will get a trailing newline
1099 willy nilly. This has its advantages insofar as you never get the
1100 "no newline at end of file" warnings from various utilities, but
1101 reality conflicts with expectations when you explicitly test for
1102 the last (or only) line *not* ending with newline, which is what
1103 the recent addtion to ref.t (5e3072707906cc4cb8a364c4cf7c487df0300caa)
1104 was doing. Adding an explicit newline makes everyone happy.

1116 such mappings into a single location for easier maintenance.

1206 [perl #81032] Overhaul Porting/epigraphs.pod
1207
1208 This patch makes multiple changes to Porting/epigraphs.pod and
1209 pod/perlhist.pod.
1210
1211 For those that don't know, Porting/epigraphs.pod is a new document that
1212 collects the quotes (chosen by Pumpkins) in perl release announcements.
1213
1214 The changes are the following.
1215
1216 1. Add a link pointing to each release announcement in the mailing
1217 list archives. These are from ysth's list, the source from which
1218 Porting/epigraphs.pod was originally compiled, but they weren't in
1219 Porting/epigraphs.pod so far.
1220 2. Reorder Porting/epigraphs.pod chronologically, because I believe
1221 that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
1222 3. Incidentally, some missing releases are added to pod/perlhist.pod too.
1223 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
1224 5. Add some epigraphs that appear in ysth's list but not in
1225 Porting/epigraphs.pod.
1226 6. I did some research in perl history before the part that ysth's list
1227 covers, and added older perl announcements I found. This work is not
1228 complete: I stopped somewhere in 2000.

1249 [perl #36347] Object destruction incomplete
1250
1251 do_clean_objs only looks for objects referenced by RVs, so blessed
1252 array references and lexical variables (and probably other SVs, too)
1253 are not DESTROYed.
1254
1255 This commit adds a new visit() call to sv_clean_objs, which curses
1256 (DESTROYs and un-blesses, leaving the reference count as it is) any
1257 objects that are still left after do_clean_named_io_objs. The new
1258 do_curse routine (a pointer to which is passeds to visit()) follows
1259 do_clean_named_io_objs’ example and explicitly skips the STDOUT and
1260 STDERR handles, in case destructors need to use them.
1261
1262 The cursing code, which is now called from two places, is moved out of
1263 sv_clear and put in its own routine. The check that the reference
1264 count is zero does not apply when called from sv_clean_objs, so the
1265 new S_curse routine takes a boolean argument that determines whether
1266 that check should take place.

1292 didn't handle overloading, even where $foo[0] was an overloaded object.

1322 Most socket ops weren't warning for unopened handles unless 'closed' was enabled
1323
1324 They were checking that category 'closed' was enabled for warnings before
1325 calling report_evil_fh(), which in turn was (correctly) checking category
1326 'unopened'.

1340 Reorganize perlhack.pod
1341
1342 Following on an IRC conversation, I've attempted to reorganize
1343 perlhack for greater clarity. I have only cut and paste blocks
1344 of text and amended section titles and levels. (I have not addressed
1345 any of the numerous factual issues which remain.)
1346
1347 The resulting guide should be clearer for those trying to skim the
1348 table of contents to understand what is covered in perlhack and
1349 whether it is worth an in-depth read.
1350
1351 I see this change as the first step towards future improvements.
