23 =head1 Core Enhancements
25 XXX New core language features go here. Summarise user-visible core language
26 enhancements. Particularly prominent performance optimisations could go
27 here, but most should go in the L</Performance Enhancements> section.
29 [ List each enhancement as a =head2 entry ]
31 =head2 New regular expression modifier C</a>
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.
51 =head2 Any unsigned value can be encoded as a character
53 With this release, Perl is adopting a model that any unsigned value can
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
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
70 Regular expression debugging output (turned on by C<use re 'debug';>) now
71 uses hexadecimal when escaping non-ASCII characters, instead of octal.
75 XXX Any security-related notices go here. In particular, any security
76 vulnerabilities closed should be noted here rather than in the

85 There are no changes intentionally incompatible with 5.XXX.XXX. If any
86 exist, they are bugs and reports are welcome.
88 [ List each incompatible change as a =head2 entry ]
90 =head2 All objects are destroyed
92 It used to be possible to prevent a destructor from being called during
93 global destruction by artificially increasing the reference count of an
96 Now such objects I<will> will be destroyed, as a result of a bug fix
97 L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>.

137 =head2 New Modules and Pragmata
143 L<CPAN::Meta::YAML> 0.003 has been added as a dual-life module. It supports a
144 subset of YAML sufficient for reading and writing META.yml and MYMETA.yml files
145 included with CPAN distributions or generated by the module installation
146 toolchain. It should not be used for any other general YAML parsing or
151 L<HTTP::Tiny> 0.009 has been added as a dual-life module. It is a very
152 small, simple HTTP/1.1 client designed for simple GET requests and file
153 mirroring. It has has been added to enable CPAN.pm and CPANPLUS to
154 "bootstrap" HTTP access to CPAN using pure Perl without relying on external
155 binaries like F<curl> or F<wget>.
159 L<JSON::PP> 2.27103 has been added as a dual-life module, for the sake of
160 reading F<META.json> files in CPAN distributions.
164 L<Module::Metadata> 1.000003 has been added as a dual-life module. It gathers
165 package and POD information from Perl module files. It is a standalone module
166 based on Module::Build::ModuleInfo for use by other module installation
167 toolchain components. Module::Build::ModuleInfo has been deprecated in
168 favor of this module instead.
172 L<Perl::OSType> 1.002 has been added as a dual-life module. It maps Perl
173 operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic types
174 with standardized names (e.g. "Unix" or "Windows"). It has been refactored
175 out of Module::Build and ExtUtils::CBuilder and consolidates such mappings into
176 a single location for easier maintenance.

495 The opcode bodies for C<chop> and C<chomp> and for C<schop> and C<schomp> have
496 been merged. The implementation functions C<Perl_do_chop()> and
497 C<Perl_do_chomp()>, never part of the public API, have been merged and moved to
498 a static function in F<pp.c>. This shrinks the perl binary slightly, and should
499 not affect any code outside the core (unless it is relying on the order of side
500 effects when C<chomp> is passed a I<list> of values).
504 Some of the flags parameters to the uvuni_to_utf8_flags() and
505 utf8n_to_uvuni() have changed. This is a result of Perl now allowing
506 internal storage and manipulation of code points that are problematic
507 in some situations. Hence, the default actions for these functions has
508 been complemented to allow these code points. The new flags are
509 documented in L<perlapi>. Code that requires the problematic code
510 points to be rejected needs to change to use these flags. Some flag
511 names are retained for backward source compatibility, though they do
512 nothing, as they are now the default. However the flags
513 C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and
514 C<UNICODE_IS_ILLEGAL> have been removed, as they stem from a
515 fundamentally broken model of how the Unicode non-character code points
516 should be handled, which is now described in
517 L<perlunicode/Non-character code points>. See also L</Selected Bug Fixes>.
521 Certain shared flags in the C<pmop.op_pmflags> and C<regexp.extflags>
522 structures have been removed. These are: C<Rxf_Pmf_LOCALE>,
523 C<Rxf_Pmf_UNICODE>, and C<PMf_LOCALE>. Instead there are encodes and
524 three static in-line functions for accessing the information:
525 C<get_regex_charset()>, C<set_regex_charset()>, and C<get_regex_charset_name()>,
526 which are defined in the places where the orginal flags were.
530 A new option has been added to C<pv_escape> to dump all characters above
531 ASCII in hexadecimal. Before, one could get all characters as hexadecimal
532 or the Latin1 non-ASCII as octal

538 XXX Important bug fixes in the core language are summarised here.

542 [ List each fix as a =item entry ]
548 The handling of Unicode non-characters has changed.
549 Previously they were mostly considered illegal, except that only one of
550 the 66 of them was known about in places. The Unicode standard
551 considers them legal, but forbids the "open interchange" of them.
552 This is part of the change to allow the internal use of any code point
553 (see L</Core Enhancements>). Together, these changes resolve

557 L<# 63446|http://rt.perl.org/rt3/Ticket/Display.html?id=63446>
561 Sometimes magic (ties, tainted, etc.) attached to variables could cause an
562 object to last longer than it should, or cause a crash if a tied variable
563 were freed from within a tie method. These have been fixed
564 L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>.
568 Most I/O functions were not warning for unopened handles unless the
569 'closed' and 'unopened' warnings categories were both enabled. Now only
570 C<use warnings 'unopened'> is necessary to trigger these warnings (as was
571 always meant to be the case.
575 C<< <expr> >> always respects overloading now if the expression is
578 Due to the way that '<> as glob' was parsed differently from
579 '<> as filehandle' from 5.6 onwards, something like C<< <$foo[0]> >> did
580 not handle overloading, even if C<$foo[0]> was an overloaded object. This
581 was contrary to the documentation for overload, and meant that C<< <> >>
582 could not be used as a general overloaded iterator operator.
586 Destructors on objects were not called during global destruction on objects
587 that were not referenced by any scalars. This could happen if an array
588 element were blessed (e.g., C<bless \$a[0]>) or if a closure referenced a
589 blessed variable (C<bless \my @a; sub foo { @a }>).
591 Now there is an extra pass during global destruction to fire destructors on
592 any objects that might be left after the usual passes that check for
593 objects referenced by scalars

631 bug database at http://rt.perl.org/perlbug/ . There may also be
632 information at http://www.perl.org/ , the Perl Home Page.
634 If you believe you have an unreported bug, please run the L<perlbug>
635 program included with your release. Be sure to trim your bug down
636 to a tiny but sufficient test case. Your bug report, along with the
637 output of C<perl -V>, will be sent off to perlbug@perl.org to be
638 analysed by the Perl porting team.
640 If the bug you are reporting has security implications, which make it
641 inappropriate to send to a publicly archived mailing list, then please send
642 it to perl5-security-report@perl.org. This points to a closed subscription
643 unarchived mailing list, which includes all the core committers, who be able
644 to help assess the impact of issues, figure out a resolution, and help

712 regcomp: Disallow multi-char folds in lookbehind
714 The addition of the ANYOFV regnode to treat multi-char folds in a bracketed
715 character class has exposed a bug, in which those classes have long been able
716 to be varying length (due to the multi-char fold), but the compiler wasn't
717 aware of it. Now it is, and hence won't allow those which have multi-char
718 folds to be part of a lookbehind pattern, which requires a constant length.

788 vastly speed up t/porting/diag.t
790 This used to take about 3 minutes of CPU. Reduce this to around
791 6 seconds (!!) by coalescing and pre-compiling various patterns
792 that get applied to nearly every line of every source file.

831 efficiciency, and easier adding of the future BOUNDA.

837 regex: Separate nodes for Unicode semantics \s \w
839 This patch converts the \s, \w and complements Unicode semantics to
840 instead of using the flags field of their nodes to instead use separate
841 nodes. This gains some efficiency, especially useful in tight loops and
842 backtracking of regexec.c, and prepares the way for easily adding other
843 semantic variations, such as /a.
845 It refactors the CCC_TRY... macros. I tried to break this piece up into
846 smaller chunks, but found it much easier to get to this in one step.
847 Further patches will do some more refactoring of these.
849 As part of the CCC_TRY macro refactoring, the lines that include the
850 test if (! nextchr) are changed to just look for the end-of-string by
851 position instead of it being NUL. In locales, it could be (however
852 unlikely), that NUL is a real alphabetic, digit, or space character.

868 CH] Change usage of regex/op common to common names
870 This patch changes the core functions to use the common names for the
871 fields that are shared between op.c and regcomp.c, just for consistency
872 of using one name throughout the core for the same thing.
874 A grep of cpan shows that both names are used in various modules; so
875 both names must be retained.

883 HTTP::Tiny has been added as a dual-life module. It is a very
884 small, simple HTTP/1.1 client designed for simple GET requests and file

886 "bootstrap" HTTP access to CPAN using pure Perl without relying on external
887 binaries like F<curl> or F<wget>.

899 Use multi-bit field for regex character set
901 The /d, /l, and /u regex modifiers are mutually exclusive. This patch
902 changes the field that stores the character set to use more than one bit
903 with an enum determining which one. This data structure more
904 closely follows the semantics of their being mutually exclusive, and
905 conserves bits as well, and is better expandable.
907 A small API is added to set and query the bit field.
909 This patch is not .xs source backwards compatible. A handful of cpan
910 programs are affected.

923 Fix \xa0 matching both [\s] [\S], et.al.
925 This bug stemmed from Latin1 characters not matching any (non-complemented)
926 character class in /d semantics when the target string is no utf8; but having
927 unicode semantics when it isn't. The solution here is to add a special flag.
929 There were several tests that relied on the broken behavior, specifically they
930 tested that \xff isn't a printable word character even in utf8. I changed the
931 deparse test to instead use a non-printable code point, and I changed the ones
932 in re_tests to be TODOs, and will change them back using /a when that is
938 restrict \p{IsUserDefined} to In\w+ and In\w+
940 In L<perlunicode/"User-Defined Character Properties">, it says you can
941 create custom properties by defining subroutines whose names begin with
942 "In" or "Is". However, perl doesn't actually enforce that naming
943 restriction, so \p{foo::bar} will call foo::Bar() if it exists.
945 This commit finally enforces this convention. Note that this broke a
946 number of existing tests for properties, since they didn't always use an
951 test that perl.pod, pod.lst, MANIFEST and the file system are consistent

959 This patch restructures the regex ANYOF code to generate ANYOFV nodes instead
960 when there is a possibility that it could match more than one character. Note
961 that this doesn't affect the optimizer, as it essentially ignores things that
962 fit into this category. (But it means that the optimizer will no longer reject
963 these when it shouldn't have.)
965 The handling of the LATIN SHARP s is modified to correspond with this new node
968 The initial handling of ANYOFV is placed in regexec.c. More analysis will come
969 on that. But there was significant change to the part that handles matching
970 multi-char strings. This has long been buggy, with it previously comparing a
971 folded-version on one side with a non-folded version on the other.
973 This patch fixes about 60% of the problems that my undelivered test suite gives
974 for multi-char folds. But there are still 17K test failures left, so I'm still
975 not delivering that. The TODOs that this fixes will be cleaned up in a later commit

984 ithread_create() was relying on the stack not moving. Fix this.
986 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
987 passing the thread creation arguments as pointers to a block of memory
988 holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
989 because the block of memory is on the Perl stack, which can move as a side
990 effect of being reallocated to extend it. Hence pass in the offset on the
991 stack instead, read the current value of the relevant interpreter's stack
992 at the point of access, and copy all the SVs away before making any further
993 calls which might cause reallocation.

1002 Correct the "unimplemented" message for get{host,net,proto,serv}ent aliases.
1004 Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a
1005 platform, they would all return 'Unsupported socket function "gethostent"
1006 called', with the analogous results for getnet{byaddr,byname,ent},
1007 getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was
1008 introduced by change af51a00e97d5c559 - prior to this, all 12 functions would
1009 report their own name when unimplemented.

1028 Generate "Unsupported socket function" stubs using PL_ppaddr.
1030 Instead of having each socket op conditionally compile as either the
1031 implementation or a DIE() depending on #HAS_SOCKET
1033 1: remove the conditional code from the ops themselves
1034 2: only compile the ops if HAS_SOCKET is defined
1035 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
1036 either the ops, or Perl_unimplemented_op
1037 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
1038 ops (ie not the "panic"... message)
1040 Whilst this complicates the support code in regen/opcode.pl, it's already a
1041 net saving of 5 lines in the C code.

1054 this, removing the only ordering dependency in the regen scripts. opcode.pl
1055 is now responsible for prototypes for pp_* functions. (embed.pl remains
1056 responsible for ck_* functions, reading from regen/opcodes)

1134 [perl #81032] Overhaul Porting/epigraphs.pod
1136 This patch makes multiple changes to Porting/epigraphs.pod and
1139 For those that don't know, Porting/epigraphs.pod is a new document that
1140 collects the quotes (chosen by Pumpkins) in perl release announcements.
1142 The changes are the following.
1144 1. Add a link pointing to each release announcement in the mailing
1145 list archives. These are from ysth's list, the source from which
1146 Porting/epigraphs.pod was originally compiled, but they weren't in
1147 Porting/epigraphs.pod so far.
1148 2. Reorder Porting/epigraphs.pod chronologically, because I believe
1149 that makes more sense -- pod/perlhist.pod is still sorted by version numbers.
1150 3. Incidentally, some missing releases are added to pod/perlhist.pod too.
1151 4. Fix a mistake where Porting/epigraphs.pod gives the wrong version number.
1152 5. Add some epigraphs that appear in ysth's list but not in
1153 Porting/epigraphs.pod.
1154 6. I did some research in perl history before the part that ysth's list
1155 covers, and added older perl announcements I found. This work is not
1156 complete: I stopped somewhere in 2000.

1174 Reorganize perlhack.pod
1176 Following on an IRC conversation, I've attempted to reorganize
1177 perlhack for greater clarity. I have only cut and paste blocks
1178 of text and amended section titles and levels. (I have not addressed
1179 any of the numerous factual issues which remain.)
1181 The resulting guide should be clearer for those trying to skim the
1182 table of contents to understand what is covered in perlhack and
1183 whether it is worth an in-depth read.
1185 I see this change as the first step towards future improvements.
