In https://rt.perl.org/Ticket/Display.html?id=119413 I bitched about p5p about deliberately breaking the B API again for no obvious technical reasons. Now I read about that summarized as: Perl 5.18.1 introduced a regression along with a bugfix for lexical subs. Some B::SPECIAL results from B::CV::GV became undefs instead. This broke Devel::Cover among other libraries. This has been fixed. [perl #119351] Excuse me? Could the person who writes such changelog lines please consult with someone who has actually an idea about what was going on? Or read the ticket. "Some B::SPECIAL results from B::CV::GV became undefs instead" This relates to 2 cases: - lexsubs which do have a NAME but no GV, so it was not fixing a regression, it rather changed behavior. For the 4th time as I outlined, and for which I have to support special cases, 3 special cases in supported maint releases. You only named Devel::Cover which is trivial test problem, and not a problem with the module itself. You didn't name any B submodule which actually need this API and a lexsub name. - main_cv->GV regression. "This has been fixed" is wrong. This has been reverted to the 5.18.0 behavior. It actually broke B modules and a bad Devel::Cover testcase. The wording of the changelog is incorrect and confusing. Anybody which has to deal with B would like to know which cases are affected. And both cases are very special. Nobody with any sanity would try to access main_cv->GV and rely in this result, because main_cv is a special case by itself. It has no name. lexsubs store the names differently which need to be accessed by a new API, introduced within a maint cycle. -- Reini Urban http://cpanel.net/ http://www.perl-compiler.org/Thread Next
