NAME

perl5264cdelta - what is new for cperl v5.26.4

DESCRIPTION

This document describes differences between the cperl 5.26.4 and the cperl 5.26.3 release.

If you are upgrading from an earlier release such as v5.26.1c, first read perl5262cdelta, which describes differences between v5.26.1c and v5.26.2c.

Modules and Pragmata

Updated Modules and Pragmata

Archive::Tar 2.32

Fix absolute path handling on VMS.

Skip white_space test on MSWin32 as Windows will report that both files exist, which is obviously a 'feature'

fix creating file with trailing whitespace on filename - fixes 103279

allow archiving with absolute pathnames - fixes 97748

Speed up extract when archive contains lots of files

CVE-2018-12015 directory traversal vulnerability [RT#125523]

bignum 0.51c

Better way to catch warnings (CPAN RT #126900).

Compress::Raw::Bzip2 2.081

pgcc support

Compress::Raw::Zlib 2.081

keep our pgcc support, keep our zlib-src fixes: deflateParams bug, FALLTHROUGH hints

Config::Perl::V 0.30_01

Add test for 5.26.1-RC1, and some cperl -V's

Fix signature with argument

Ignore ccache and compiler path in signature

Add default_inc_excludes_dot

use vars => our

Cpanel::JSON::XS 4.06

Added json_type support, ...

Cwd 4.75c

Fixed long pathnames test for getcwd() on older systems, like debian-7.11 i386, which still returns ENAMETOOLONG on large enough buffers.

Fix the HAS_GET_CURRENT_DIR_NAME check, and the is_ENAMETOOLONG macro.

For getcwd with get_current_dir_name() - i.e. fastcwd - add abs_path. See also http://perl11.org/blog/fastcwd.html

Data::Dumper 2.172

Restore deparsing support in the XS dumper, on Perl 5.18 and earlier.

Fix bug when dumping globs with quoting (which now happens for all Unicode glob names)

Behavior change: $dumper-Useqq(undef)> is now treated as setting the "useqq" option, not getting it (and similarly for other options) [perl #113090]

Quote glob names better; notably, Unicode globs are now handled correctly. [perl #119831]

DB_File 1.842

Document the MacOS build failures & how MacPort can work around the issue. RT #125238, RT #125585, RT #133280

Write all test db files into a directory created by File::Temp Protects against any possible races if running a parallel build.

#96357: DB_File destructor is not thread-safe Added CLONE_SKIP to DB_File.pm and included the test db-threads.t from the patch. Note - This only works with perl >= 5.8.7

Digest::SHA 6.02

Silenced compiler warnings from VS2017 RT #124477

DynaLoader 2.09c

Fix wrong usage of SvREFCNT_inc_simple_NN with a function, fixes a memory leak.

dl_load_file: set NULL xs (bootstrap). When we find the bootname via dl_find_symbol early, we still need to set xs from dl_install_xsub().

Encode 2.98

no strict hashpairs in encoding. fixed some -Wsign-compare See https://metacpan.org/changes/distribution/Encode

Skip the flapping test t/Aliases.t on threaded smokers, with random segfaults. This is a long standing core bug, with PMOP aliases or clone. First observed at https://github.com/rurban/perl-compiler/issues/73 (since 5.6)

Stop directory tweaking $Encode::Encoding{utf8}

Fix gcc warnings for older gcc < 4.0

experimental 0.020_01

eval use feature, minor test fix. Add the declared_refs feature. Enable lexical_topic for cperl 5.24, added perl5 compat.

Exporter 5.73

More use vars => our

ExtUtils::Constant 0.25_01

extend stack by one

ExtUtils::MakeMaker 8.35_06

Merge our fixes to upstream 7.35_06 (which has e.g. the dlltool mingw and parallel MSVC fixes). Many fixes were already in, but some new upstream bugs crept in.

Support IO::Scalar handle as $parsefile argument to ExtUtils::MM_Unix::parse_version().

fix Invalid Locale symbol name. Invalid identifier "ENCODING_UTF-8" while "strict names"

fix XSMULTI static with strict linkers, avoid duplicate symbol _boot_XS__Test in: Test.o blib/arch/auto/XS/Test/Test.a(Test.o)

Fix symlink abort crossing mountpoint with CPAN::Distribution previous directory ~/.cpan/build changed before entering tmp-32186, expected dev=47 ino=244719549, actual dev=47 ino=33303, aborting at CPAN/Distribution.pm line 591

Fix method of generating names for dummy users and groups during testing (i.e. under docker) [cpan #121967].

File::Temp 0.2308

- remove File::Temp::Dir from the PAUSE index (it is not in its own .pm file, so it is not 'use'able on its own)

- change EXLOCK default from true to false; addresses RT#123959. Note that this option was always a no-op on non-BSD platforms; changing the default to false makes behaviour more predictable and consistent across platforms.

- switch from 'use vars' to 'our'

- documentation updates for what versions contain what features (thanks, Brian Mowrey! RT#101518)

- fix bad use of skip() in tests (RT#95922)

new codes

Math::BigInt 1.999814

Scalar::Util 1.50_11

fix find_rundefsvoffset logic

Fix t/subname.t and t/exotic_names.t for unstrict names. perl5.26 started defining $Config{usecperl} as 'UNKNOWN', hence this check is now unreliable.

Merge with 1.50 upstream: Ensure pairmap extends its stack correctly (davem) Fix name of List::Util::unpairs in its error messages

added head/tail honor PERL_NO_QUOTE_PKGSEPERATOR merged %DB::sub tests merge with upstream %DB::sub support (main:: or not, utf8)

Storable 3.12_02

Enable >2GB AvFILL check on store_hook (64bit).

Too many references returned by STORABLE_freeze. It wrapped around previously. Fixes Coverity CID #187854. This is a security issue on 64bit cperl and perl5, as both allow SSize_t arrays.

Thread::Queue 3.13

[RT #125868] Fix tests for Test::Simple 1.302138

threads 2.22_01

Fix Clang macro backward compatibility per patch by Andy Grundman. Keep the old better doc. Keep our modglobal fix in global destruction from 2.12_01.

Support PL_sv_zero. Don't Copy() null pointer

The documentation now better describes the problems that arise when returning values from threads, and no longer warns about creating threads in BEGIN blocks. [perl #96538]

threads::shared 1.58

Fix Clang macro backward compatibility per patch by Andy Grundman. RT #131124 Memory allocation fix.

Time::HiRes 1.9758_01

Updated from upstream since 1.9752:

See https://metacpan.org/changes/distribution/Time-HiRes

Fix MSVC by adding a fake struct timezone.

Add more potential clock constants, like CLOCK_MONOTONIC_FAST (available in FreeBSD), and not all potentially found clock constants were properly exported to be available from Perl, see your system's clock_gettime() documentation for the available ones

Merged with our cperl fixes, esp. no __ANONIO__ See https://github.com/rurban/Time-HiRes/commits/cperl

Time::Local 1.28

Some tests which required support for epoch values larger than 2**32 were not being skipped when the underlying Perl did not support that.

Fixed the tests so they will not break in the year 2020. The tests were passing in 2-digit years on the assumption that a year like "70" would be treated as 1970, but starting in 2020 this would be treated as 2070 instead. Reported by Bernhard M. Wiedemann. RT #124787.

Added timelocal_modern and timegm_modern variants as optional exports. These versions do not munge years at all. They treat the year value that they are given exactly as-is.

Time::Piece 1.33

Switch to XSLoader.

Fix AIX compile

Fix compile errors on MS

Use macro for buf sizes

Remove some compile warnings

SP off by 1 in _crt_localtime

version 0.9924_02
