| Subject: | [PATCH] CLONE method for multithread/Apache2-worker-MPM support |
version 1.24 fails when loaded under Apache2 multithreaded worker MPM
typical error msg is
No map found matching for GLOB(0xb7896f0) at
/usr/share/perl5/Cache/Memcached.pm line 671.
Problem is that spawning a new ithread changes the memory addresses of
the socket globs, which then messes up %sock_map.
Patch provides a CLONE method to rebuild %sock_map in the new thread.
(...probably also need to do locking around the various get/set methods,
but at least users can do that much themselves...)
