=head1 NAME

[ this is a template for a new perldelta file. Any text flagged as
XXX needs to be processed before release. ]

perldelta - what is new for perl v5.11.3

=head1 DESCRIPTION

This document describes differences between the 5.11.3 release and
the 5.11.3 release.

If you are upgrading from an earlier release such as 5.11.3, first read
the L<perl5XXXdelta>, which describes differences between 5.11.3 and
5.10.0

=head1 Notice

XXX Any important notices here

=head1 Incompatible Changes

XXX For a release on a stable branch, this section aspires to be:

    There are no changes intentionally incompatible with 5.11.3. If any
    exist, they are bugs and reports are welcome.


=head1 Core Enhancements

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.

=head2 Unicode version

Perl is shipped with the latest Unicode version, 5.2, October 2009.  See
L<http://www.unicode.org/versions/Unicode5.2.0> for details about this release
of Unicode.

But, an installation can now fairly easily change Perl to operate on any
Unicode release.  Perl is shipped with the latest official release, but
an installation can download and install any prior release from Unicode, and
cause Perl to work with that (or even multiple releases).  Instructions are in
L<perlunicode>.

=head2 Unicode properties

Perl can now handle every Unicode character property.  A new pod,
L<perluniprops>, lists all available non-Unihan character properties.  By
default the Unihan properties and certain others (deprecated and Unicode
internal-only ones) are not exposed.  See below for more details on
these; there is also a section in the pod listing them, and why they are
not exposed.

Perl now fully supports the Unicode compound-style of using C<=> and C<:>
in writing regular expressions: C<\p{property=value}> and
C<\p{property:value}> (both of which mean the same thing).

Perl now supports fully the Unicode loose matching rules for text
between the braces in C<\p{...}> constructs.  In addition, Perl also allows
underscores between digits of numbers.

All the Unicode-defined synonyms for properties and property values are
now accepted.

C<qr/\X/>, which matches a Unicode logical character, has been expanded to work
better with various Asian languages.  It now is defined as an C<extended
grapheme cluster>.  (See L<http://www.unicode.org/reports/tr29/>).  One change
due to this is that C<\X> will match the whole sequence C<S<CR LF>>.  Another
change is that C<\X> will match an isolated mark.  Marks generally come after a
base character, but it is possible in Unicode to have them in isolation, and
C<\X> will now handle that case.  Otherwise, this change should be transparent
for the non-affected languages.

C<\p{...}> matches using the Canonical_Combining_Class property were
completely broken in previous Perls.  This is now fixed.

In previous Perls, the Unicode Decomposition_Type=Compat property and a
Perl extension had the same name, which led to neither matching all the
correct values (with more than 100 mistakes in one, and several thousand
in the other).  The Perl extension has now been renamed to be
Decomposition_Type=Noncanonical (short: dt=noncanon).  It has the same
meaning as was previously intended, namely the union of all the
non-canonical Decomposition types, with Unicode Compat being just one of
those.

C<\p{Uppercase}> and C<\p{Lowercase}> have been brought into line with the
Unicode definitions.  This means they each match a few more characters
than previously.

C<\p{Cntrl}> now matches the same characters as C<\p{Control}>.  This means it
no longer will match Private Use (gc=co), Surrogates (gc=cs), nor Format
(gc=cf) code points.  The Format code points represent the biggest
possible problem.  All but 36 of them are either officially deprecated
or strongly discouraged from being used.  Of those 36, likely the most
widely used are the soft hyphen (U+00AD), and BOM, ZWSP, ZWNJ, WJ, and
similar, plus Bi-directional controls.

C<\p{Alpha}> now matches the same characters as C<\p{Alphabetic}>.  The Perl
definition included a number of things that aren't really alpha (all
marks), while omitting many that were.  The Unicode definition is
clearly better, so we are switching to it.  As a direct consequence, the
definitions of C<\p{Alnum}> and C<\p{Word}> which depend on Alpha also change.

C<\p{Word}> also now doesn't match certain characters it wasn't supposed
to, such as fractions.

C<\p{Print}> no longer matches the line control characters: tab, lf, cr,
ff, vt, and nel.  This brings it in line with the documentation.

\p{Decomposition_Type=Canonical} now includes the Hangul syllables

The Numeric type property has been extended to include the Unihan
characters.

There is a new Perl extension, the 'Present_In', or simply 'In'
property.  This is an extension of the Unicode Age property, but
C<\p{In=5.0}> matches any code point whose usage has been determined as of
Unicode version 5.0.  The C<\p{Age=5.0}> only matches code points added in 5.0.

A number of properties did not have the correct values for unassigned
code points.  This is now fixed.  The affected properties are
Bidi_Class, East_Asian_Width, Joining_Type, Decomposition_Type,
Hangul_Syllable_Type, Numeric_Type, and Line_Break.

The Default_Ignorable_Code_Point, ID_Continue, and ID_Start properties
have been updated to their current definitions.

Certain properties that are supposed to be Unicode internal-only were
erroneously exposed by previous Perls.  Use of these in regular
expressions will now generate a deprecated warning message, if those
warnings are enabled.  The properties are: Other_Alphabetic,
Other_Default_Ignorable_Code_Point, Other_Grapheme_Extend,
Other_ID_Continue, Other_ID_Start, Other_Lowercase, Other_Math, and
Other_Uppercase.

An installation can now fairly easily change which Unicode properties
Perl understands.  As mentioned above, certain properties are by default
turned off.  These include all the Unihan properties (which should be
accessible via the CPAN module Unicode::Unihan) and any deprecated or
Unicode internal-only property that Perl has never exposed.

The files in the To directory are now more clearly marked as being
stable, directly usable by applications.  New hash entries in them give
the format of the normal entries which allows for easier machine
parsing.  Perl can generate files in this directory for any property,
though most are suppressed.  An installation can choose to change which
get written.   Instructions are in L<perluniprops>.

=head1 New Platforms

XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
go here, in a list ordered by distribution name. Minimally it should be the
module version, but it's more useful to the end user to give a paragraph's
summary of the module's changes. In an ideal world, dual-life modules would
have a F<Changes> file that could be cribbed.

=head1 Reporting Bugs

If you find what you think is a bug, you might check the articles
recently posted to the comp.lang.perl.misc newsgroup and the perl
bug database at http://rt.perl.org/perlbug/ .  There may also be
information at http://www.perl.org/ , the Perl Home Page.

If you believe you have an unreported bug, please run the B<perlbug>
program included with your release.  Be sure to trim your bug down
to a tiny but sufficient test case.  Your bug report, along with the
output of C<perl -V>, will be sent off to perlbug@perl.org to be
analysed by the Perl porting team.

If the bug you are reporting has security implications, which make it
inappropriate to send to a publicly archived mailing list, then please send
it to perl5-security-report@perl.org. This points to a closed subscription
unarchived mailing list, which includes all the core committers, who be able
to help assess the impact of issues, figure out a resolution, and help
co-ordinate the release of patches to mitigate or fix the problem across all
platforms on which Perl is supported. Please only use this address for
security issues in the Perl core, not for modules independently
distributed on CPAN.

    Export PL_curinterp symbol for MULTIPLICITY without USE_ITHREADS
    
    This is necessary for XS extensions that define PERL_CORE.  In that
    situation PERL_GET_CONTEXT will resolve to PL_curinterp, which is
    normally not exported (extensions call Perl_Gcurinterp_ptr() to get a
    pointer to PL_curinterp instead). With USE_ITHREADS defined
    PERL_GET_CONTEXT will expand to Perl_get_context() even inside the
    core because the context needs to be fetched from threadlocal storage.

    In this case my %x = %$x assigns a hash to itself. This causes the
    hv_clear in pp_aassign to wipe away the hash before it can be copied.
    The â\80\98panic: attempt to copy freed scalarâ\80\99 error is triggered by this
    line, which copies the value:
        sv_setsv(tmpstr,*relem);        /* value */
    
    The solution is to make sure the OPpASSIGN_COMMON flag is on in such
    cases, so that pp_aassign copies everything before doing the assignment.

    [perl #70764] $' fails to initialized for pre-compiled regular expression matches
    
    The match vars are associated with the regexp that last matched
    successfully. In the case of $str =~ $qr or /$qr/, since the $qr could
    be used in multiple scopes that need their own sets of match vars, the
    $qr is cloned by Perl_reg_temp_copy as of change 30677/28d8d7f. This
    happens in pp_regcomp before pp_match has stringified the LHS, hence the
    bug. In short, /$gror/ is not equivalent to
    ($which = !$which) ? /$gror/ : /$gror/, which is weird.

    Throw away uncleanable scopes when exiting a pseudo-forked process.
    
    Commit adab9969 tried to clean up those additional scopes, but failed
    because some of the memory was allocated from a different pool. To
    avoid triggering the assert() in perl_destruct() this change instead
    moves the one remaining scope back to the root of the stack, effectively
    discarding the additional frames without any further processing.

    [perl #71076] sort with active sub (5.10 regression)
    
    One of the tests in sort.t causes a bus error (or sometimes â\80\98Undefined
    subroutine calledâ\80\99) if run multiple times. This is because sort
    decreases the refcount of an active sub used as a comparison routine.

    Ensure that pp_qr returns a new regexp SV each time. Resolves RT #69852.
    
    Instead of returning a(nother) reference to the (pre-compiled) regexp in the
    optree, use reg_temp_copy() to create a copy of it, and return a reference to
    that. This resolves issues about Regexp::DESTROY not being called in a timely
    fashion (the original bug tracked by RT #69852), as well as bugs related to
    blessing regexps, and of assigning to regexps, as described in correspondence
    added to the ticket.
    
    It transpires that we also need to undo the SvPVX() sharing when ithreads
    cloning a Regexp SV, because mother_re is set to NULL, instead of a cloned
    copy of the mother_re. This change might fix bugs with regexps and threads in
    certain other situations, but as yet neither tests nor bug reports have
    indicated any problems, so it might not actually be an edge case that it's
    possible to reach.

    mktables performance improvement
    
    The attached patch got the easiest performance improvements to mktables.
    Hopefully this is good enough for now.
    
    This involved:
    
    1) Nicholas' patch
    2) I stored complete_name instead of recomputing it each time.
    3) Used $_[xxx] instead of shift in very heavily used subroutines
    4) removed trace accidentally left in.
    
    I also changed the misspelled subroutine name discovered by Craig Berry.
    I searched for any other misspellings and didn't find any.
    
    Also removed trailing white space that keeps creeping back in, and now
    this doesn't generate pod entries if not outputting a pod file, and
    clarified warning message if no mktables.lst is present.
    
    I couldn't figure out a way to conditionally use 'no overloading', as
    it is called at compile time.  So I just commented out the old stuff
    that will work for 5.8, with a note about using that if you want to
    use 5.8

    perl-5.11.2 breaks NYTProf savesrc option (Lexer API suspected)
    
    Tim Bunce wrote:
    >The primary issue is the off-by-one error in the array indexing.
    
    There's a bit more to it than that.  The indexing was off-by-one for
    *some* places that process a new line, but correct for others, so the
    saved source as a whole was mangled rather than simply offset.  Also,
    there were some redundant calls to update_debugger_info(), so some lines
    got saved twice, in some cases off-by-one for one saving and not for
    the other.  The saved source is, therefore, hopelessly broken in 5.11.2.
    
    Attached patch fixes the source saving.  Includes a new test, which works
    through all reachable places that source lines get saved.  This should
    close RT #70804.

    Add code and starting perldoc for warnings::fatal_enabled.
    
    This is an analog for warnings::enabled, except it tests whether the
    given category has been set fatal using "use warnings FATAL => foo".
    This is mostly for symmetry.
    
    Assumes that the fatal bit for a category will have an offset one higher
    than the regular bit for the category, because otherwise much rewriting
    of __chk would be required.

    Always add a manifest resource to perl.exe to specify the <trustInfo>
    settings for Windows Vista and later.  Without this setting Windows
    will treat perl.exe as a legacy application and apply various
    heuristics like redirecting access to protected file system areas
    (like the "Program Files" folder) to the users "VirtualStore"
    instead of generating a proper "permission denied" error.
    
    For VC8 and VC9 this manifest setting is automatically generated by
    the compiler/linker (together with the binding information for their
    respective runtime libraries); for all other compilers we need to
    embed the manifest resource explicitly in the external resource file.
    
    This change also requests the Microsoft Common-Controls version 6.0
    (themed controls introduced in Windows XP) via the dependency list
    in the assembly manifest.  For VC8 and VC9 this is specified using the
    /manifestdependency linker commandline option instead.
