+perldelta - what is new for perl v5.13.9
=head1 DESCRIPTION
-This document describes differences between the 5.13.7 release and
-the 5.13.8 release.
+This document describes differences between the 5.13.8 release and
+the 5.13.9 release.
+
+If you are upgrading from an earlier release such as 5.13.7, first read
+L<perl5138delta>, which describes differences between 5.13.7 and
+5.13.8.
+
+=head1 Notice
-If you are upgrading from an earlier release such as 5.13.6, first read
-L<perl5137delta>, which describes differences between 5.13.6 and
-5.13.7.
+XXX Any important notices here
=head1 Core Enhancements
-=head2 C<-d:-foo> calls C<Devel::foo::unimport>
+XXX New core language features go here. Summarise user-visible core language
+enhancements. Particularly prominent performance optimisations could go
+here, but most should go in the L</Performance Enhancements> section.
+
+[ List each enhancement as a =head2 entry ]
+
+=head2 New regular expression modifier C</a>
+
+The C</a> regular expression modifier restricts C<\s> to match precisely
+the five characters C<[ \f\n\r\t]>, C<\d> to match precisely the 10
+characters C<[0-9]>, C<\w> to match precisely the 63 characters
+C<[A-Za-z0-9_]>, and the Posix (C<[[:posix:]]>) character classes to
+match only the appropriate ASCII characters. The complements, of
+course, match everything but; and C<\b> and C<\B> are correspondingly
+affected. Otherwise, C</a> behaves like the C</u> modifier, in that
+case-insensitive matching uses Unicode semantics; for example, "k" will
+match the Unicode C<\N{KELVIN SIGN}> under C</i> matching, and code
+points in the Latin1 range, above ASCII will have Unicode semantics when
+it comes to case-insensitive matching. Like its cousins (C</u>, C</l>,
+and C</d>), and in spite of the terminology, C</a> in 5.14 will not
+actually be able to be used as a suffix at the end of a regular
+expression (this restriction is planned to be lifted in 5.16). It must
+occur either as an infix modifier, such as C<(?a:...)> or (C<(?a)...>,
+or it can be turned on within the lexical scope of C<use re '/a'>.
+Turning on C</a> turns off the other "character set" modifiers.
+
+=head2 Any unsigned value can be encoded as a character
+
+With this release, Perl is adopting a model that any unsigned value can
+be treated as a code point and encoded internally (as utf8) without
+warnings -- not just the code points that are legal in Unicode.
+However, unless utf8 warnings have been
+explicitly lexically turned off, outputting or performing a
+Unicode-defined operation (such as upper-casing) on such a code point
+will generate a warning. Attempting to input these using strict rules
+(such as with the C<:encoding('UTF-8')> layer) will continue to fail.
+Prior to this release the handling was very inconsistent, and incorrect
+in places. Also, the Unicode non-characters, some of which previously were
+erroneously considered illegal in places by Perl, contrary to the Unicode
+standard, are now always legal internally. But inputting or outputting
+them will work the same as for the non-legal Unicode code points, as the
+Unicode standard says they are illegal for "open interchange".
+
+=head2 Regular expression debugging output improvement
+
+Regular expression debugging output (turned on by C<use re 'debug';>) now
+uses hexadecimal when escaping non-ASCII characters, instead of octal.
+
+=head1 Security
+
+XXX Any security-related notices go here. In particular, any security
+vulnerabilities closed should be noted here rather than in the
+L</Selected Bug Fixes> section.
+
+[ List each security issue as a =head2 entry ]
-The syntax C<-dI<B<:>foo>> was extended in 5.6.1 to make C<-dI<:fooB<=bar>>>
-equivalent to C<-MDevel::foo=bar>, which expands
-internally to C<use Devel::foo 'bar';>.
-F<perl> now allows prefixing the module name with C<->, with the same
-semantics as C<-M>, I<i.e.>
+=head1 Incompatible Changes
-=over 4
+XXX For a release on a stable branch, this section aspires to be:
-=item C<-d:-foo>
+ There are no changes intentionally incompatible with 5.XXX.XXX. If any
+ exist, they are bugs and reports are welcome.
-Equivalent to C<-M-Devel::foo>, expands to
-C<no Devel::foo;>, calls C<< Devel::foo->unimport() >>
-if the method exists.
+[ List each incompatible change as a =head2 entry ]
-=item C<-d:-foo=bar>
+=head2 All objects are destroyed
-Equivalent to C<-M-Devel::foo=bar>, expands to C<no Devel::foo 'bar';>,
-calls C<< Devel::foo->unimport('bar') >> if the method exists.
+It used to be possible to prevent a destructor from being called during
+global destruction by artificially increasing the reference count of an
+object.
-=back
+Now such objects I<will> will be destroyed, as a result of a bug fix
+L<[perl #81230]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=81230>.
-This is particularly useful to suppresses the default actions of a
-C<Devel::*> module's C<import> method whilst still loading it for debugging.
+This has the potential to break some XS modules. (In fact, it break some.
+See L</Known Problems>, below.)
-=head2 Filehandle method calls load L<IO::File> on demand
+=head1 Deprecations
-When a method call on a filehandle would die because the method cannot
-be resolved, and L<IO::File> has not been loaded, Perl now loads L<IO::File>
-via C<require> and attempts method resolution again:
+XXX Any deprecated features, syntax, modules etc. should be listed here.
+In particular, deprecated modules should be listed here even if they are
+listed as an updated module in the L</Modules and Pragmata> section.
- open my $fh, ">", $file;
- $fh->binmode(":raw"); # loads IO::File and succeeds
+[ List each deprecation as a =head2 entry ]
-This also works for globs like STDOUT, STDERR and STDIN:
+=head1 Performance Enhancements
- STDOUT->autoflush(1);
+XXX Changes which enhance performance without changing behaviour go here. There
+may well be none in a stable release.
-Because this on-demand load only happens if method resolution fails, the
-legacy approach of manually loading an L<IO::File> parent class for partial
-method support still works as expected:
+[ List each enhancement as a =item entry ]
- use IO::Handle;
- open my $fh, ">", $file;
- $fh->autoflush(1); # IO::File not loaded
+=over 4
-=head2 Full functionality for C<use feature 'unicode_strings'>
+=item *
-This release provides full functionality for C<use feature
-'unicode_strings'>. Under its scope, all string operations executed and
-regular expressions compiled (even if executed outside its scope) have
-Unicode semantics. See L<feature>.
+XXX
-This feature avoids most forms of the "Unicode Bug" (See
-L<perlunicode/The "Unicode Bug"> for details.) If there is a
-possibility that your code will process Unicode strings, you are
-B<strongly> encouraged to use this subpragma to avoid nasty surprises.
+=back
-The availability of this should strongly affect the whole tone of
-various documents, such as L<perlunicode> and L<perluniintro>, but this
-work has not been done yet.
+=head1 Modules and Pragmata
-=head2 Exception Handling Backcompat Hack
+XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
+go here. If Module::CoreList is updated, generate an initial draft of the
+following sections using F<Porting/corelist-perldelta.pl>, which prints stub
+entries to STDOUT. Results can be pasted in place of the '=head2' entries
+below. A paragraph summary for important changes should then be added by hand.
+In an ideal world, dual-life modules would have a F<Changes> file that could be
+cribbed.
-When an exception is thrown in an C<eval BLOCK>, C<$@> is now set before
-unwinding, as well as being set after unwinding as the eval block exits. This
-early setting supports code that has historically treated C<$@> during unwinding
-as an indicator of whether the unwinding was due to an exception. These modules
-had been broken by 5.13.1's change from setting C<$@> early to setting it late.
-This double setting arrangement is a stopgap until the reason for unwinding can
-be made properly introspectable. C<$@> has never been a reliable indicator of
-the reason for unwinding.
+[ Within each section, list entries as a =item entry ]
-=head2 printf-like functions understand post-1980 size modifiers
+=head2 New Modules and Pragmata
-Perl's printf and sprintf operators, and Perl's internal printf replacement
-function, now understand the C90 size modifiers "hh" (C<char>), "z"
-(C<size_t>), and "t" (C<ptrdiff_t>). Also, when compiled with a C99
-compiler, Perl now understands the size modifier "j" (C<intmax_t>).
+=over 4
-So, for example, on any modern machine, C<sprintf('%hhd', 257)> returns '1'.
+=item *
-=head2 DTrace probes now include package name
+L<CPAN::Meta::YAML> 0.003 has been added as a dual-life module. It supports a
+subset of YAML sufficient for reading and writing META.yml and MYMETA.yml files
+included with CPAN distributions or generated by the module installation
+toolchain. It should not be used for any other general YAML parsing or
+generation task.
-The DTrace probes now include an additional argument (C<arg3>) which contains
-the package the subroutine being entered or left was compiled in.
+=item *
-For example using the following DTrace script:
+L<HTTP::Tiny> 0.009 has been added as a dual-life module. It is a very
+small, simple HTTP/1.1 client designed for simple GET requests and file
+mirroring. It has has been added to enable CPAN.pm and CPANPLUS to
+"bootstrap" HTTP access to CPAN using pure Perl without relying on external
+binaries like F<curl> or F<wget>.
- perl$target:::sub-entry
- {
- printf("%s::%s\n", copyinstr(arg0), copyinstr(arg3));
- }
+=item *
-and then running:
+L<JSON::PP> 2.27103 has been added as a dual-life module, for the sake of
+reading F<META.json> files in CPAN distributions.
- perl -e'sub test { }; test'
+=item *
-DTrace will print:
+L<Module::Metadata> 1.000003 has been added as a dual-life module. It gathers
+package and POD information from Perl module files. It is a standalone module
+based on Module::Build::ModuleInfo for use by other module installation
+toolchain components. Module::Build::ModuleInfo has been deprecated in
+favor of this module instead.
- main::test
+=item *
-=head2 Stacked labels
+L<Perl::OSType> 1.002 has been added as a dual-life module. It maps Perl
+operating system names (e.g. 'dragonfly' or 'MSWin32') to more generic types
+with standardized names (e.g. "Unix" or "Windows"). It has been refactored
+out of Module::Build and ExtUtils::CBuilder and consolidates such mappings into
+a single location for easier maintenance.
-Multiple statement labels can now appear before a single statement.
+=back
-=head1 Incompatible Changes
+=head2 Updated Modules and Pragmata
-=head2 C<:=> is now a syntax error
+=over 4
-Previously C<my $pi := 4;> was exactly equivalent to C<my $pi : = 4;>,
-with the C<:> being treated as the start of an attribute list, ending before
-the C<=>. The use of C<:=> to mean C<: => was deprecated in 5.12.0, and is now
-a syntax error. This will allow the future use of C<:=> as a new token.
+=item *
-We find no Perl 5 code on CPAN using this construction, outside the core's
-tests for it, so we believe that this change will have very little impact on
-real-world codebases.
+C<Archive::Extract> has been upgraded from version 0.46 to 0.48
-If it is absolutely necessary to have empty attribute lists (for example,
-because of a code generator) then avoid the error by adding a space before
-the C<=>.
+=item *
-=head2 Run-time code block in regular expressions
+C<Archive::Tar> has been upgraded from version 1.74 to 1.76
-Code blocks in regular expressions (C<(?{...})> and C<(??{...})>) used not
-to inherit any pragmata (strict, warnings, etc.) if the regular expression
-was compiled at run time as happens in cases like these two:
+=item *
- use re 'eval';
- $foo =~ $bar; # when $bar contains (?{...})
- $foo =~ /$bar(?{ $finished = 1 })/;
+C<CGI> has been upgraded from version 3.50 to 3.51
-This was a bug, which has now been fixed. But it has the potential to break
-any code that was relying on this bug.
+Further improvements have been made to guard against newline injections
+in headers.
-=head1 Deprecations
+=item *
-=head2 C<?PATTERN?> is deprecated
+C<Compress::Raw::Bzip2> has been upgraded from version 2.031 to 2.033
-C<?PATTERN?> (without the initial m) has been deprecated and now produces
-a warning. This is to allow future use of C<?> in new operators.
-The match-once functionality is still available in the form of C<m?PATTERN?>.
+=item *
-=head2 C<sv_compile_2op()> is now deprecated
+C<Compress::Raw::Zlib> has been upgraded from version 2.030 to 2.033
-The C<sv_compile_2op()> API function is now deprecated. Searches suggest
-that nothing on CPAN is using it, so this should have zero impact.
+=item *
-It attempted to provide an API to compile code down to an optree, but failed
-to bind correctly to lexicals in the enclosing scope. It's not possible to
-fix this problem within the constraints of its parameters and return value.
+C<CPAN> has been upgraded from version 1.94_62 to 1.94_63
-=head2 Tie functions on scalars holding typeglobs
+=item *
-Calling a tie function (C<tie>, C<tied>, C<untie>) with a scalar argument
-acts on a file handle if the scalar happens to hold a typeglob.
+C<CPANPLUS> has been upgraded from version 0.9010 to 0.9011
-This is a long-standing bug that will be removed in Perl 5.16, as
-there is currently no way to tie the scalar itself when it holds
-a typeglob, and no way to untie a scalar that has had a typeglob
-assigned to it.
+=item *
-This bug was fixed in 5.13.7 but, because of the breakage it caused, the
-fix has been reverted. Now there is a deprecation warning whenever a tie
-function is used on a handle without an explicit C<*>.

-C<mro> has been upgraded from version 1.05 to 1.06.
+Some of the flags parameters to the uvuni_to_utf8_flags() and

+internal storage and manipulation of code points that are problematic
+in some situations. Hence, the default actions for these functions has
+been complemented to allow these code points. The new flags are
+documented in L<perlapi>. Code that requires the problematic code
+points to be rejected needs to change to use these flags. Some flag
+names are retained for backward source compatibility, though they do
+nothing, as they are now the default. However the flags
+C<UNICODE_ALLOW_FDD0>, C<UNICODE_ALLOW_FFFF>, C<UNICODE_ILLEGAL>, and

-C<eval "BEGIN{die}"> no longer leaks memory on non-threaded builds.
+ regex: Use ANYOFV
-=item *
+ This patch restructures the regex ANYOF code to generate ANYOFV nodes instead
+ when there is a possibility that it could match more than one character. Note
+ that this doesn't affect the optimizer, as it essentially ignores things that
+ fit into this category. (But it means that the optimizer will no longer reject
+ these when it shouldn't have.)
-PerlIO no longer crashes when called recursively, e.g., from a signal
-handler. Now it just leaks memory
-L<[perl #75556]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=75556>.
+ The handling of the LATIN SHARP s is modified to correspond with this new node
+ type.
-=item *
+ The initial handling of ANYOFV is placed in regexec.c. More analysis will come
+ on that. But there was significant change to the part that handles matching
+ multi-char strings. This has long been buggy, with it previously comparing a
+ folded-version on one side with a non-folded version on the other.
-Defining a constant with the same name as one of perl's special blocks
-(e.g., INIT) stopped working in 5.12.0, but has now been fixed
-L<[perl #78634]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=78634>.
+ This patch fixes about 60% of the problems that my undelivered test suite gives
+ for multi-char folds. But there are still 17K test failures left, so I'm still
+ not delivering that. The TODOs that this fixes will be cleaned up in a later commit
-=item *
-A reference to a literal value used as a hash key (C<$hash{\"foo"}>) used
-to be stringified, even if the hash was tied

-A closure containing an C<if> statement followed by a constant or variable
-is no longer treated as a constant
-L<[perl #63540]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=63540>.
+ ithread_create() was relying on the stack not moving. Fix this.
-=item *
+ 4cf5eae5e58faebb changed S_ithread_create() to avoid creating an AV, by
+ passing the thread creation arguments as pointers to a block of memory
+ holding SVs. Unfortunately, this inadvertently introduced a subtle bug,
+ because the block of memory is on the Perl stack, which can move as a side
+ effect of being reallocated to extend it. Hence pass in the offset on the
+ stack instead, read the current value of the relevant interpreter's stack
+ at the point of access, and copy all the SVs away before making any further
+ calls which might cause reallocation.
-Calling a closure prototype (what is passed to an attribute handler for a
-closure) now results in a "Closure prototype called" error message instead
-of a crash
-L<[perl #68560]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=68560>.
+ Update to Win32-0.44 from CPAN
+ Update IO-Compress to CPAN version 2.033
+ Update Compress-Raw-Zlib to CPAN version 2.033
+ Update Compress-Raw-Bzip2 to CPAN version 2.033
+ Update DB_File to CPAN version 1.821
-=item *
+DIAGNOSTICS
+ Correct the "unimplemented" message for get{host,net,proto,serv}ent aliases.
-A regular expression optimisation would sometimes cause a match with a
-C<{n,m}> quantifier to fail when it should match
-L<[perl #79152]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=79152>.
+ Previously, if all of gethost{byaddr,byname,ent} were unimplemented on a
+ platform, they would all return 'Unsupported socket function "gethostent"
+ called', with the analogous results for getnet{byaddr,byname,ent},
+ getproto{byname,bynumber,ent} and getserv{byname,byport,ent}. This bug was
+ introduced by change af51a00e97d5c559 - prior to this, all 12 functions would
+ report their own name when unimplemented.
-=item *
-What has become known as the "Unicode Bug" is mostly resolved in this release.
-Under C<use feature 'unicode_strings'>, the internal storage format of a
-string no longer affects the external semantics. There are two known
-exceptions. User-defined case changing functions, which are planned to
-be deprecated in 5.14, require utf8-encoded strings to function; and the
-character C<LATIN SMALL LETTER SHARP S> in regular expression
-case-insensitive matching has a somewhat different set of bugs depending
-on the internal storage format. Case-insensitive matching of all
-characters that have multi-character matches, as this one does, is
-problematical in Perl.

+ Instead of having each socket op conditionally compile as either the
+ implementation or a DIE() depending on #HAS_SOCKET
-=item *
+ 1: remove the conditional code from the ops themselves
+ 2: only compile the ops if HAS_SOCKET is defined
+ 3: general conditional code for the intialisation of PL_ppaddr - as appropriate
+ either the ops, or Perl_unimplemented_op
+ 4: Amend Perl_unimplemented_op to generate the appropriate DIE() for socket
+ ops (ie not the "panic"... message)
-C<state> can now be used with attributes. It used to mean the same thing as
-C<my> if attributes were present
-L<[perl #68658]|http://rt.perl.org/rt3/Public/Bug/Display.html?id=68658>.
+ Whilst this complicates the support code in regen/opcode.pl, it's already a

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

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