=head1 NAME

perl5222delta - what is new for perl v5.22.2

=head1 DESCRIPTION

This document describes differences between the 5.22.1 release and the 5.22.2
release.

If you are upgrading from an earlier release such as 5.22.0, first read
L<perl5221delta>, which describes differences between 5.22.0 and 5.22.1.

=head1 Security

=head2 Fix out of boundary access in Win32 path handling

This is CVE-2015-8608.  For more information see
L<[perl #126755]|https://rt.perl.org/Ticket/Display.html?id=126755>.

=head2 Fix loss of taint in C<canonpath()>

This is CVE-2015-8607.  For more information see
L<[perl #126862]|https://rt.perl.org/Ticket/Display.html?id=126862>.

=head2 Set proper umask before calling C<mkstemp(3)>

In 5.22.0 perl started setting umask to C<0600> before calling C<mkstemp(3)>
and restoring it afterwards.  This wrongfully tells C<open(2)> to strip the
owner read and write bits from the given mode before applying it, rather than
the intended negation of leaving only those bits in place.

Systems that use mode C<0666> in C<mkstemp(3)> (like old versions of glibc)
create a file with permissions C<0066>, leaving world read and write permissions
regardless of current umask.

This has been fixed by using umask C<0177> instead.

L<[perl #127322]|https://rt.perl.org/Ticket/Display.html?id=127322>

=head2 Avoid accessing uninitialized memory in Win32 C<crypt()>

Validation that will detect both a short salt and invalid characters in the
salt has been added.

L<[perl #126922]|https://rt.perl.org/Ticket/Display.html?id=126922>

=head2 Remove duplicate environment variables from C<environ>

Previously, if an environment variable appeared more than once in C<environ[]>,
L<C<%ENV>|perlvar/%ENV> would contain the last entry for that name, while a
typical C<getenv()> would return the first entry.  We now make sure C<%ENV>
contains the same as what C<getenv()> returns.

Secondly, we now remove duplicates from C<environ[]>, so if a setting with that
name is set in C<%ENV> we won't pass an unsafe value to a child process.

This is CVE-2016-2381.

=head1 Incompatible Changes

There are no changes intentionally incompatible with Perl 5.22.1.  If any
exist, they are bugs, and we request that you submit a report.  See
L</Reporting Bugs> below.

=head1 Modules and Pragmata

=head2 Updated Modules and Pragmata

=over 4

=item *

L<File::Spec> has been upgraded from version 3.56 to 3.56_01.

C<canonpath()> now preserves taint.  See L</"Fix loss of taint in
C<canonpath()>">.

=item *

L<Module::CoreList> has been upgraded from version 5.20151213 to 5.20160429.

The version number of L<Digest::SHA> listed for Perl 5.18.4 was wrong and has
been corrected.  Likewise for the version number of L<Config> in 5.18.3 and
5.18.4.
L<[perl #127624]|https://rt.perl.org/Ticket/Display.html?id=127624>

=back

=head1 Documentation

=head2 Changes to Existing Documentation

=head3 L<perldiag>

=over 4

=item *

The explanation of the warning "unable to close filehandle %s properly: %s"
which can occur when doing an implicit close of a filehandle has been expanded
and improved.

=back

=head3 L<perlfunc>

=over 4

=item *

The documentation of L<C<hex()>|perlfunc/hex> has been revised to clarify valid
inputs.

=back

=head1 Configuration and Compilation

=over 4

=item *

Dtrace builds now build successfully on systems with a newer dtrace that
require an input object file that uses the probes in the F<.d> file.

Previously the probe would fail and cause a build failure.

L<[perl #122287]|https://rt.perl.org/Ticket/Display.html?id=122287>

=item *

F<Configure> no longer probes for F<libnm> by default.  Originally this was the
"New Math" library, but the name has been re-used by the GNOME NetworkManager.

L<[perl #127131]|https://rt.perl.org/Ticket/Display.html?id=127131>

=item *

F<Configure> now knows about gcc 5.

=item *

Compiling perl with B<-DPERL_MEM_LOG> now works again.

=back

=head1 Platform Support

=head2 Platform-Specific Notes

=over 4

=item Darwin

Compiling perl with B<-Dusecbacktrace> on Darwin now works again.

L<[perl #127764]|https://rt.perl.org/Ticket/Display.html?id=127764>

=item OS X/Darwin

Builds with both B<-DDEBUGGING> and threading enabled would fail with a "panic:
free from wrong pool" error when built or tested from Terminal on OS X.  This
was caused by perl's internal management of the environment conflicting with an
atfork handler using the libc C<setenv()> function to update the environment.

Perl now uses C<setenv()>/C<unsetenv()> to update the environment on OS X.

L<[perl #126240]|https://rt.perl.org/Ticket/Display.html?id=126240>

=item ppc64el

The floating point format of ppc64el (Debian naming for little-endian PowerPC)
is now detected correctly.

=item Tru64

A test failure in F<t/porting/extrefs.t> has been fixed.

=back

=head1 Internal Changes

=over 4

=item *

An unwarranted assertion in C<Perl_newATTRSUB_x()> has been removed.  If a stub
subroutine definition with a prototype has been seen, then any subsequent stub
(or definition) of the same subroutine with an attribute was causing an
assertion failure because of a null pointer.

L<[perl #126845]|https://rt.perl.org/Ticket/Display.html?id=126845>

=back

=head1 Selected Bug Fixes

=over 4

=item *

Calls to the placeholder C<&PL_sv_yes> used internally when an C<import()> or
C<unimport()> method isn't found now correctly handle scalar context.
L<[perl #126042]|https://rt.perl.org/Ticket/Display.html?id=126042>

=item *

The L<C<pipe()>|perlfunc/pipe> operator would assert for C<DEBUGGING> builds
instead of producing the correct error message.  The condition asserted on is
detected and reported on correctly without the assertions, so the assertions
were removed.
L<[perl #126480]|https://rt.perl.org/Ticket/Display.html?id=126480>

=item *

In some cases, failing to parse a here-doc would attempt to use freed memory.
This was caused by a pointer not being restored correctly.
L<[perl #126443]|https://rt.perl.org/Ticket/Display.html?id=126443>

=item *

Perl now reports more context when it sees an array where it expects to see an
operator, and avoids an assertion failure.
L<[perl #123737]|https://rt.perl.org/Ticket/Display.html?id=123737>

=item *

If a here-doc was found while parsing another operator, the parser had already
read end of file, and the here-doc was not terminated, perl could produce an
assertion or a segmentation fault.  This now reliably complains about the
unterminated here-doc.
L<[perl #125540]|https://rt.perl.org/Ticket/Display.html?id=125540>

=item *

Parsing beyond the end of the buffer when processing a C<#line> directive with
no filename is now avoided.
L<[perl #127334]|https://rt.perl.org/Ticket/Display.html?id=127334>

=item *

Perl 5.22.0 added support for the C99 hexadecimal floating point notation, but
sometimes misparsed hex floats.  This has been fixed.
L<[perl #127183]|https://rt.perl.org/Ticket/Display.html?id=127183>

=item *

Certain regex patterns involving a complemented posix class in an inverted
bracketed character class, and matching something else optionally would
improperly fail to match.  An example of one that could fail is
C<qr/_?[^\Wbar]\x{100}/>.  This has been fixed.
L<[perl #127537]|https://rt.perl.org/Ticket/Display.html?id=127537>

=item *

Fixed an issue with L<C<pack()>|perlfunc/pack> where C<< pack "H" >> (and
C<< pack "h" >>) could read past the source when given a non-utf8 source and a
utf8 target.
L<[perl #126325]|https://rt.perl.org/Ticket/Display.html?id=126325>

=item *

Fixed some cases where perl would abort due to a segmentation fault, or a
C-level assert.
L<[perl #126193]|https://rt.perl.org/Ticket/Display.html?id=126193>
L<[perl #126257]|https://rt.perl.org/Ticket/Display.html?id=126257>
L<[perl #126258]|https://rt.perl.org/Ticket/Display.html?id=126258>
L<[perl #126405]|https://rt.perl.org/Ticket/Display.html?id=126405>
L<[perl #126602]|https://rt.perl.org/Ticket/Display.html?id=126602>
L<[perl #127773]|https://rt.perl.org/Ticket/Display.html?id=127773>
L<[perl #127786]|https://rt.perl.org/Ticket/Display.html?id=127786>

=item *

A memory leak when setting C<$ENV{foo}> on Darwin has been fixed.
L<[perl #126240]|https://rt.perl.org/Ticket/Display.html?id=126240>

=item *

Perl now correctly raises an error when trying to compile patterns with
unterminated character classes while there are trailing backslashes.
L<[perl #126141]|https://rt.perl.org/Ticket/Display.html?id=126141>

=item *

C<NOTHING> regops and C<EXACTFU_SS> regops in C<make_trie()> are now handled
properly.
L<[perl #126206]|https://rt.perl.org/Ticket/Display.html?id=126206>

=item *

Perl now only tests C<semctl()> if we have everything needed to use it.  In
FreeBSD the C<semctl()> entry point may exist, but it can be disabled by
policy.
L<[perl #127533]|https://rt.perl.org/Ticket/Display.html?id=127533>

=item *

A regression that allowed undeclared barewords as hash keys to work despite
strictures has been fixed.
L<[perl #126981]|https://rt.perl.org/Ticket/Display.html?id=126981>

=item *

As an optimization (introduced in Perl 5.20.0), L<C<uc()>|perlfunc/uc>,
L<C<lc()>|perlfunc/lc>, L<C<ucfirst()>|perlfunc/ucfirst> and
L<C<lcfirst()>|perlfunc/lcfirst> sometimes modify their argument in-place
rather than returning a modified copy.  The criteria for this optimization has
been made stricter to avoid these functions accidentally modifying in-place
when they should not, which has been happening in some cases, e.g. in
L<List::Util>.

=item *

Excessive memory usage in the compilation of some regular expressions involving
non-ASCII characters has been reduced.  A more complete fix is forthcoming in
Perl 5.24.0.

=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
https://rt.perl.org/ .  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 L<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 will 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.
