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.

125 =head2 New Modules and Pragmata
131 L<CPAN::Meta::YAML> 0.003 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
139 L<HTTP::Tiny> 0.009 has been added as a dual-life module. It is a very
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
142 "bootstrap" HTTP access to CPAN using pure Perl without relying on external
143 binaries like F<curl> or F<wget>.
147 L<Module::Metadata> 1.000003 has been added as a dual-life module. It gathers
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.
155 L<Perl::OSType> 1.002 has been added as a dual-life module. It maps Perl
156 operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic types
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.

459 [ List each test improvement as a =item entry ]
465 The opcode bodies for C<chop> and C<chomp> and for C<schop> and C<schomp> have
466 been merged. The implementation functions C<Perl_do_chop()> and
467 C<Perl_do_chomp()>, never part of the public API, have been merged and moved to
468 a static function in F<pp.c>. This shrinks the perl binary slightly, and should
469 not affect any code outside the core (unless it is relying on the order of side
470 effects when C<chomp> is passed a I<list> of values).
474 Some of the flags parameters to the uvuni_to_utf8_flags() and
475 utf8n_to_uvuni() have changed. This is a result of Perl now allowing
476 internal storage and manipulation of code points that are problematic
477 in some situations. Hence, the default actions for these functions has
478 been complemented to allow these code points. The new flags are
479 documented in L<perlapi>. Code that requires the problematic code
480 points to be rejected needs to change to use these flags. Some flag
481 names are retained for backward source compatibility, though they do
482 nothing, as they are now the default. However the flags
483 C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and
484 C<UNICODE_IS_ILLEGAL> have been removed, as they stem from a
485 fundamentally broken model of how the Unicode non-character code points
486 should be handled, which is now described in
487 L<perlunicode/Non-character code points>. See also L</Selected Bug Fixes>.
491 Certain shared flags in the C<pmop.op_pmflags> and C<regexp.extflags>
492 structures have been removed. These are: C<Rxf_Pmf_LOCALE>,
493 C<Rxf_Pmf_UNICODE>, and C<PMf_LOCALE>. Instead there are encodes and
494 three static in-line functions for accessing the information:
495 C<get_regex_charset()>, C<set_regex_charset()>, and C<get_regex_charset_name()>,
496 which are defined in the places where the orginal flags were.
500 A new option has been added to C<pv_escape> to dump all characters above
501 ASCII in hexadecimal. Before, one could get all characters as hexadecimal
502 or the Latin1 non-ASCII as octal

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

531 Sometimes magic (ties, tainted, etc.) attached to variables could cause an
532 object to last longer than it should, or cause a crash if a tied variable
533 were freed from within a tie method. These have been fixed

569 recently posted to the comp.lang.perl.misc newsgroup and the perl
570 bug database at http://rt.perl.org/perlbug/ . There may also be
571 information at http://www.perl.org/ , the Perl Home Page.
573 If you believe you have an unreported bug, please run the L<perlbug>
574 program included with your release. Be sure to trim your bug down
575 to a tiny but sufficient test case. Your bug report, along with the
576 output of C<perl -V>, will be sent off to perlbug@perl.org to be
577 analysed by the Perl porting team.
579 If the bug you are reporting has security implications, which make it
580 inappropriate to send to a publicly archived mailing list, then please send
581 it to perl5-security-report@perl.org. This points to a closed subscription
582 unarchived mailing list, which includes all the core committers, who be able
583 to help assess the impact of issues, figure out a resolution, and help
584 co-ordinate the release of patches to mitigate or fix the problem across all
585 platforms on which Perl is supported. Please only use this address for

651 regcomp: Disallow multi-char folds in lookbehind
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.

782 regex: Separate nodes for Unicode semantics \s \w
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.
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.
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.

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

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

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

844 Use multi-bit field for regex character set
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.
852 A small API is added to set and query the bit field.
854 This patch is not .xs source backwards compatible. A handful of cpan
855 programs are affected.

868 Fix \xa0 matching both [\s] [\S], et.al.
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.
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
883 restrict \p{IsUserDefined} to In\w+ and In\w+
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.
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
896 test that perl.pod, pod.lst, MANIFEST and the file system are consistent

904 This patch restructures the regex ANYOF code to generate ANYOFV nodes instead
905 when there is a possibility that it could match more than one character. Note
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.)
910 The handling of the LATIN SHARP s is modified to correspond with this new node
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.
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.
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.

973 utf8.c(): Default to allow problematic code points
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.)
979 This affects uvuni_to_utf8_flags(), utf8n_to_uvuni() and various routines that
980 are specialized interfaces to them.
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.
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.

999 Instead of having each socket op conditionally compile as either the

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)

1096 Make newline on last record explicit.
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.

1206 [perl #81032] Overhaul Porting/epigraphs.pod
1208 This patch makes multiple changes to Porting/epigraphs.pod and
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.
1214 The changes are the following.
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
1251 do_clean_objs only looks for objects referenced by RVs, so blessed
1252 array references and lexical variables (and probably other SVs, too)
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.
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.

1272 [perl #73630] Build separate DTrace for miniperl
1274 As outlined in the RT ticket due to miniperl's dependencies differing to
1275 the final perl binary dtrace -G needs to be called separately for each.
1277 Build tested on Mac OS X 10.6, Solaris 11 and Scientific Linux with
1280 (Solaris is the only system I have access to where DTRACE_O actually gets
1281 defined. Neither the dtrace binary on OS X nor SystemTap's dtrace
1282 compatibility layer accept the -G option.)

1288 make <expr> always overload if expr is overloaded
1290 Due to the way that '<> as glob' was parsed differently from
1291 '<> as filehandle' from 5.6 onwards, something like <$foo[0]>
1292 didn't handle overloading, even where $foo[0] was an overloaded object.
1293 This was contrary to the docs for overload, and meant that <> couldn't
1294 be used as a general overloaded iterator operator.

1300 perlbug did not previously generate a From: header. While some MTAs do
1301 the "right" thing and insert a valid "From:", not all of them do,
1302 potentially resulting in dropped mail.

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

1340 Reorganize perlhack.pod
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.)
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.
1351 I see this change as the first step towards future improvements.
