One bug causes lexical state in one file to +leak into another that is required/used from it. This bug, [perl #68590], was +present from Perl 5.6 up to Perl 5.10, fixed in Perl 5.11.0. 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. + +WWW: http://search.cpan.org/dist/Lexical-SealRequireHints/ diff --git a/devel/p5-Lexical-SealRequireHints/pkg-plist b/devel/p5-Lexical-SealRequireHints/pkg-plist index 2425edc1e2e3..4320bf687e45 100644 --- a/devel/p5-Lexical-SealRequireHints/pkg-plist +++ b/devel/p5-Lexical-SealRequireHints/pkg-plist @@ -1,7 +1,7 @@ %%SITE_PERL%%/%%PERL_ARCH%%/Lexical/SealRequireHints.pm +%%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints/.packlist %%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints/SealRequireHints.bs %%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints/SealRequireHints.so -%%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints/.packlist -@dirrmtry %%SITE_PERL%%/%%PERL_ARCH%%/Lexical -@dirrmtry %%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints +@dirrm %%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical/SealRequireHints @dirrmtry %%SITE_PERL%%/%%PERL_ARCH%%/auto/Lexical +@dirrmtry %%SITE_PERL%%/%%PERL_ARCH%%/Lexical |
