perl-Lexical-SealRequireHints-0.011-bp155.2.11 RPM for s390x

From OpenSuSE Leap 15.5 for s390x

This module works around two historical bugs in Perl's handling of the
'%^H' (lexical hints) variable. One bug causes lexical state in one file to
leak into another that is 'require'd/'use'd from it. This bug, [perl

The second bug causes lexical state (normally a blank '%^H' once the first
bug is fixed) to leak outwards from 'utf8.pm', if it is automatically
loaded during Unicode regular expression matching, into whatever source is
compiling at the time of the regexp match. This bug, [perl #73174], was
present from Perl 5.8.7 up to Perl 5.11.5, fixed in Perl 5.12.0.

Both of these bugs seriously damage the usability of any module relying on
'%^H' for lexical scoping, on the affected Perl versions. It is in practice
essential to work around these bugs when using such modules. On versions of
Perl that require such a workaround, this module globally changes the
behaviour of 'require', including 'use' and the implicit 'require'
performed in Unicode regular expression matching, so that it no longer
exhibits these bugs.

The workaround supplied by this module takes effect the first time its
'import' method is called. Typically this will be done by means of a 'use'
statement. This should be done as early as possible, because it only
affects 'require'/'use' statements that are compiled after the workaround
goes into effect. For 'use' statements, and 'require' statements that are
executed immediately and only once, it suffices to invoke the workaround
when loading the first module that will set up vulnerable lexical state.
Delayed-action 'require' statements, however, are more troublesome, and can
require the workaround to be loaded much earlier. Ultimately, an affected
Perl program may need to load the workaround as very nearly its first
action. Invoking this module multiple times, from multiple modules, is not
a problem: the workaround is only applied once, and applies to everything
subsequently compiled.

This module is implemented in XS, with a pure Perl backup version for
systems that can't handle XS modules. The XS version has a better chance of
playing nicely with other modules that modify 'require' handling. The pure
Perl version can't work at all on some Perl versions; users of those
versions must use the XS. On all Perl versions suffering the underlying
hint leakage bug, pure Perl hooking of 'require' breaks the use of
'require' without an explicit parameter (implicitly using '$_').

Changelog

* Tue Jul 25 2017 coolo@suse.com
  - updated to 0.011
    see /usr/share/doc/packages/perl-Lexical-SealRequireHints/Changes
    version 0.011; 2017-07-15
    * update test suite to not rely on . in @INC, which is no longer
      necessarily there from Perl 5.25.7
    * no longer include a Makefile.PL in the distribution
    * update op-munging code to the PERL_OP_PARENT-compatible style
      (though none of it is actually used on Perls new enough to support
      PERL_OP_PARENT)
    * rename internal gen_*_op() functions into a better style
    * consistently use THX_ prefix on internal function names
* Wed Mar 23 2016 coolo@suse.com
  - updated to 0.010
    see /usr/share/doc/packages/perl-Lexical-SealRequireHints/Changes
    version 0.010; 2016-03-18
    * skip test with lexical $_ on Perl 5.23.4+ where that feature has
      been removed
* Mon Apr 13 2015 coolo@suse.com
  - updated to 0.009
    see /usr/share/doc/packages/perl-Lexical-SealRequireHints/Changes
    version 0.009; 2015-03-20
    * in test of require for version checking, work around [perl #124135]
      which was introduced in Perl 5.21.4
    version 0.008; 2015-03-20
    * bugfix: don't localise hints around a version-number require, so that
      "use v5.10.0" can have its intentional effect of setting feature flags
    * bugfix: in pure Perl implementation, use a ($) prototype on
      CORE::GLOBAL::require, so that the argument expression will be in
      the correct context
    * better error message for refusing to use pure Perl implementation
      on Perl 5.9.4 to 5.10.0
    * document that the pure Perl implementation breaks the use of the
      implicit $_ parameter with require
    * in swash test, don't fail if utf8.pm was loaded unexpectedly early,
      as has been seen to happen on some systems
    * test idempotence
    * fix test for thread safety, which risked false negatives
    * when preemptively loading Carp and Carp::Heavy, avoid the Perl core
      bug regarding the context applied to file scope of required modules,
      in case of future versions of those modules becoming vulnerable and
      running on an old Perl
    * declare correct version for Test::More dependency
    * typo fix in documentation
    * typo fix in a comment
* Thu Feb 27 2014 coolo@suse.com
  - initial package 0.007
