Bug #18001 for Bundle-CPAN: reload cpan locked up

Subject:

reload cpan locked up

Hello. I started up cpan and it informed me there was a new version of Bundle::CPAN and recommended I do install Bundle::CPAN reload cpan so I did. The install Bundle::CPAN seemed to work fine, but the reload cpan locked up hard. Evenutally, I was able to kill it. After removing the lock file, all seems to be well. I just thought you might like to know. Tim Show quoted text

I encoutered the same case recently. Should be a bug of new version. Thanks for inform, although I am not the maintainer of cpan ;-) On Sun Mar 05 19:39:43 2006, guest wrote: Show quoted text

Oh my, I finally got around to visiting this ugly, ugly bug. It was SO trivial: IFF during 'reload cpan' some temporary inconsistency of otherwise sane and working code arises, THEN it may happen that AUTOLOAD is called. And IFF AUTOLOAD calls an inconsistent function or method, then we have an endless loop. It is reproducable by using 'reload cpan' to load illegal perl code. CPAN 1.88_51 now fixed this problem by watching the recursion level within AUTOLOAD and refusing to AUTOLOAD recursively. Enjoy and Thanks for your patience,
