NAME
perldelta - what is new for perl v5.22.2
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
perl5221delta, which describes differences between 5.22.0 and 5.22.1.
Security
Fix out of boundary access in Win32 path handling
This is CVE-2015-8608. For more information see [perl #126755]
<https://rt.perl.org/Ticket/Display.html?id=126755>.
Fix loss of taint in "canonpath()"
This is CVE-2015-8607. For more information see [perl #126862]
<https://rt.perl.org/Ticket/Display.html?id=126862>.
Set proper umask before calling mkstemp(3)
In 5.22.0 perl started setting umask to 0600 before calling mkstemp(3)
and restoring it afterwards. This wrongfully tells 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 0666 in mkstemp(3) (like old versions of glibc)
create a file with permissions 0066, leaving world read and write
permissions regardless of current umask.
This has been fixed by using umask 0177 instead.
[perl #127322] <https://rt.perl.org/Ticket/Display.html?id=127322>
Avoid accessing uninitialized memory in Win32 "crypt()"
Validation that will detect both a short salt and invalid characters in
the salt has been added.
://rt.perl.org/Ticket/Display.html?id=126922>
Remove duplicate environment variables from "environ"
Previously, if an environment variable appeared more than once in
"environ[]", %ENV would contain the last entry for that name, while a
typical "getenv()" would return the first entry. We now make sure %ENV
contains the same as what "getenv()" returns.
Secondly, we now remove duplicates from "environ[]", so if a setting
with that name is set in %ENV we won't pass an unsafe value to a child
process.
This is CVE-2016-2381.
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
"Reporting Bugs" below.
Modules and Pragmata
Updated Modules and Pragmata
• File::Spec has been upgraded from version 3.56 to 3.56_01.
"canonpath()" now preserves taint. See "Fix loss of taint in
"canonpath()"".
• Module::CoreList has been upgraded from version 5.20151213 to
5.20160429.
The version number of Digest::SHA listed for Perl 5.18.4 was wrong
and has been corrected. Likewise for the version number of Config
in 5.18.3 and 5.18.4. [perl #127624]
<https://rt.perl.org/Ticket/Display.html?id=127624>
Documentation
Changes to Existing Documentation
perldiag
• 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.
perlfunc
• The documentation of "hex()" has been revised to clarify valid
inputs.
Configuration and Compilation
• Dtrace builds now build successfully on systems with a newer dtrace
that require an input object file that uses the probes in the .d
file.
Previously the probe would fail and cause a build failure.
[perl #122287] <https://rt.perl.org/Ticket/Display.html?id=122287>
• Configure no longer probes for libnm by default. Originally this
was the "New Math" library, but the name has been re-used by the
GNOME NetworkManager.
[perl #127131] <https://rt.perl.org/Ticket/Display.html?id=127131>
• Configure now knows about gcc 5.
• Compiling perl with -DPERL_MEM_LOG now works again.
Platform Support
Platform-Specific Notes
Darwin
Compiling perl with -Dusecbacktrace on Darwin now works again.
[perl #127764] <https://rt.perl.org/Ticket/Display.html?id=127764>
OS X/Darwin
Builds with both -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
"setenv()" function to update the environment.
Perl now uses "setenv()"/"unsetenv()" to update the environment on
OS X.
[perl #126240] <https://rt.perl.org/Ticket/Display.html?id=126240>
ppc64el
The floating point format of ppc64el (Debian naming for little-
endian PowerPC) is now detected correctly.
Tru64
A test failure in t/porting/extrefs.t has been fixed.
Internal Changes
• An unwarranted assertion in "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.
[perl #126845] <https://rt.perl.org/Ticket/Display.html?id=126845>
Selected Bug Fixes
• Calls to the placeholder &PL_sv_yes used internally when an
"import()" or "unimport()" method isn't found now correctly handle
scalar context. [perl #126042]
<https://rt.perl.org/Ticket/Display.html?id=126042>
• The "pipe()" operator would assert for "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. [perl #126480]
<https://rt.perl.org/Ticket/Display.html?id=126480>
• 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. [perl #126443]
<https://rt.perl.org/Ticket/Display.html?id=126443>
• Perl now reports more context when it sees an array where it
expects to see an operator, and avoids an assertion failure. [perl
#123737] <https://rt.perl.org/Ticket/Display.html?id=123737>
• 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. [perl #125540]
<https://rt.perl.org/Ticket/Display.html?id=125540>
• Parsing beyond the end of the buffer when processing a "#line"
directive with no filename is now avoided. [perl #127334]
<https://rt.perl.org/Ticket/Display.html?id=127334>
• Perl 5.22.0 added support for the C99 hexadecimal floating point
notation, but sometimes misparsed hex floats. This has been fixed.
[perl #127183] <https://rt.perl.org/Ticket/Display.html?id=127183>
• 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 "qr/_?[^\Wbar]\x{100}/". This has been fixed. [perl
#127537] <https://rt.perl.org/Ticket/Display.html?id=127537>
• Fixed an issue with "pack()" where "pack "H"" (and "pack "h"")
could read past the source when given a non-utf8 source and a utf8
target. [perl #126325]
<https://rt.perl.org/Ticket/Display.html?id=126325>
• Fixed some cases where perl would abort due to a segmentation
fault, or a C-level assert. [perl #126193]
<https://rt.perl.org/Ticket/Display.html?id=126193> [perl #126257]
<https://rt.perl.org/Ticket/Display.html?id=126257> [perl #126258]
<https://rt.perl.org/Ticket/Display.html?id=126258> [perl #126405]
<https://rt.perl.org/Ticket/Display.html?id=126405> [perl #126602]
<https://rt.perl.org/Ticket/Display.html?id=126602> [perl #127773]
<https://rt.perl.org/Ticket/Display.html?id=127773> [perl #127786]
<https://rt.perl.org/Ticket/Display.html?id=127786>
• A memory leak when setting $ENV{foo} on Darwin has been fixed.
[perl #126240] <https://rt.perl.org/Ticket/Display.html?id=126240>
• Perl now correctly raises an error when trying to compile patterns
with unterminated character classes while there are trailing
backslashes. [perl #126141]
<https://rt.perl.org/Ticket/Display.html?id=126141>
• "NOTHING" regops and "EXACTFU_SS" regops in "make_trie()" are now
handled properly. [perl #126206]
<https://rt.perl.org/Ticket/Display.html?id=126206>
• Perl now only tests "semctl()" if we have everything needed to use
it. In FreeBSD the "semctl()" entry point may exist, but it can be
disabled by policy. [perl #127533]
<https://rt.perl.org/Ticket/Display.html?id=127533>
• A regression that allowed undeclared barewords as hash keys to work
despite strictures has been fixed. [perl #126981]
<https://rt.perl.org/Ticket/Display.html?id=126981>
• As an optimization (introduced in Perl 5.20.0), "uc()", "lc()",
"ucfirst()" and "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 List::Util.
• 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.
Acknowledgements
Perl 5.22.2 represents approximately 5 months of development since Perl
5.22.1 and contains approximately 3,000 lines of changes across 110
files from 24 authors.
Excluding auto-generated files, documentation and release tools, there
were approximately 1,500 lines of changes to 52 .pm, .t, .c and .h
files.
Perl continues to flourish into its third decade thanks to a vibrant
community of users and developers. The following people are known to
have contributed the improvements that became Perl 5.22.2:
Aaron Crane, Abigail, Andreas Koenig, Aristotle Pagaltzis, Chris
'BinGOs' Williams, Craig A. Berry, Dagfinn Ilmari Mannsaaker, David
Golden, David Mitchell, H.Merijn Brand, James E Keenan, Jarkko
Hietaniemi, Karen Etheridge, Karl Williamson, Matthew Horsfall, Niko
Tyni, Ricardo Signes, Sawyer X, Stevan Little, Steve Hay, Todd Rinaldo,
Tony Cook, Vladimir Timofeev, Yves Orton.
The list above is almost certainly incomplete as it is automatically
generated from version control history. In particular, it does not
include the names of the (very much appreciated) contributors who
reported issues to the Perl bug tracker.
Many of the changes included in this version originated in the CPAN
modules included in Perl's core. We're grateful to the entire CPAN
community for helping Perl to flourish.
For a more complete list of all of Perl's historical contributors,
please see the AUTHORS file in the Perl source distribution.
The symbol 'main' is multiply defined because Perl 5's `Configure`
script erroneously appends `try.c`, instead of overwriting it.
This change backports an upstream patch, which will not be needed once
Perl 5 5.23.x is available.

Several bugs, including a segmentation fault, have been fixed with the bounds checking constructs (introduced in Perl 5.22) \b{gcb}, \b{sb}, \b{wb}, \B{gcb}, \B{sb}, and \B{wb}. All the \B{} ones now match an empty string; none of the \b{} ones do.
* Module::CoreList has been upgraded from version 5.20150520 to 5.20151213.
* PerlIO::scalar has been upgraded from version 0.22 to 0.23.
* POSIX has been upgraded from version 1.53 to 1.53_01.
* Storable has been upgraded from version 2.53 to 2.53_01.
* warnings has been upgraded from version 1.32 to 1.34.
* Win32 has been upgraded from version 0.51 to 0.52.
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.
something in op.c (as miniop.c) is mis-compiled with this option which
is enabled by -O2, when using GCC 4.5. i didn't try to figure out
exactly what as op.c is 419,359 bytes long and the assembler output
is almost 100% different and approximiately 1.5MB either way (the
diff of the asm output is larger than the combined inputs), so for now
we have this hack. this problem doesn't appear to occur in newer GCC.
XXX: pullup to 2015Q2.
Add a Configure test to verify that including <fenv.h> doesn't produce
a build error, as it will in quite few cases on NetBSD on archs which
are not amd64, i386 or sparc in NetBSD 6.x. If the test build fails,
pretend we don't have fenv.h.
Validated that the result builds on NetBSD/evbarm 6.0 and NetBSD/i386 6.1.5.
Build fix, so no need to bump PKGREVISION.
OK by wiz@
* A safer ARGV
* CGI.pm and Module::Build disappear from core
* Hexadecimal floating point values
* Variable aliases
* Repetition in list assignment
* List pipe opens on Win32
* Various small fixes

An ambiguity in the documentation of the ellipsis statement has
been corrected. [perl #122661]
Diagnostics
The following additions or changes have been made to diagnostic
output, including warnings and fatal error messages. For the complete
list of diagnostic messages, see perldiag. Changes to Existing
Diagnostics

new, but was not previously documented here.
Testing
The test script re/rt122747.t has been added to verify that perl
#122747 remains fixed.
Platform Support Regained Platforms
IRIX and Tru64 platforms are working again. (Some make test failures
remain.) Selected Bug Fixes
AIX now sets the length in getsockopt correctly. [perl #120835],
[cpan #91183], [cpan #85570]
In Perl 5.20.0, $^N accidentally had the internal UTF8 flag turned
off if accessed from a code block within a regular expression,
effectively UTF8-encoding the value. This has been fixed. [perl
#123135]
Various cases where the name of a sub is used (autoload,
overloading, error messages) used to crash for lexical subs, but
have been fixed.
An assertion failure when parsing sort with debugging enabled has
been fixed. [perl #122771]
Loading UTF8 tables during a regular expression match could cause
assertion failures under debugging builds if the previous match
used the very same regular expression. [perl #122747]
Due to a mistake in the string-copying logic, copying the value of
a state variable could instead steal the value and undefine the
variable. This bug, introduced in Perl 5.20, would happen mostly
for long strings (1250 chars or more), but could happen for any
strings under builds with copy-on-write disabled. [perl #123029]
Fixed a bug that could cause perl to execute an infinite loop
during compilation. [perl #122995]
On Win32, restoring in a child pseudo-process a variable that was
local()ed in a parent pseudo-process before the fork happened
caused memory corruption and a crash in the child pseudo-process
(and therefore OS process). [perl #40565]
Tainted constants evaluated at compile time no longer cause
unrelated statements to become tainted. [perl #122669]
Calling write on a format with a ^** field could produce a panic
in sv_chop() if there were insufficient arguments or if the
variable used to fill the field was empty. [perl #123245]
In Perl 5.20.0, sort CORE::fake where 'fake' is anything other
than a keyword started chopping of the last 6 characters and
treating the result as a sort sub name. The previous behaviour of
treating "CORE::fake" as a sort sub name has been restored. [perl
#123410]
A bug in regular expression patterns that could lead to segfaults
and other crashes has been fixed. This occurred only in patterns
compiled with "/i", while taking into account the current POSIX
locale (this usually means they have to be compiled within the
scope of "use locale"), and there must be a string of at least 128
consecutive bytes to match. [perl #123539]
qr/@array(?{block})/ no longer dies with "Bizarre copy of
ARRAY". [perl #123344]
gmtime no longer crashes with not-a-number values. [perl #123495]
Certain syntax errors in substitutions, such as s/${<>{})//, would
crash, and had done so since Perl 5.10. (In some cases the crash
did not start happening until Perl 5.16.) The crash has, of
course, been fixed. [perl #123542]
A memory leak in some regular expressions, introduced in Perl
5.20.1, has been fixed. [perl #123198]
formline("@...", "a"); would crash. The FF_CHECKNL case in
pp_formline() didn't set the pointer used to mark the chop
position, which led to the FF_MORE case crashing with a
segmentation fault. This has been fixed. [perl #123538] [perl
#123622]
A possible buffer overrun and crash when parsing a literal pattern
during regular expression compilation has been fixed. [perl
#123604]
Known Problems
It is a known bug that lexical subroutines cannot be used as the
SUBNAME argument to sort. This will be fixed in a future version
of Perl.
Errata From Previous Releases
A regression has been fixed that was introduced in Perl 5.20.0
(fixed in Perl 5.20.1 as well as here) in which a UTF-8 encoded
regular expression pattern that contains a single ASCII lowercase
letter does not match its uppercase counterpart. [perl #122655]
Changes include performance enhancements and various bug fixes.
Perl 5.20.1 represents approximately 4 months of development since Perl 5.20.0 and contains approximately 12,000 lines of changes across 170 files from 36 authors.
/boot/common/lib.
Undef it for Haiku and COMPILER_LIB_DIRS instead (also for other platforms
not set here).
XXX: all platforms should be SYSLIBPATH=${COMPILER_LIB_DIRS}, or
XXX: _OPSYS_LIB_DIRS for such platforms should be fixed.
