[issue13103] copy of an asyncore dispatcher causes infinite recursion

Giampaolo Rodola' added the comment: asyncore's __getattr__ horror was scheduled for removal a long ago (3.1 as per issue8483). We can safely remove it for 3.4 and fix the RuntimeError exception above for all the earlier Python versions which are affected. -- _

[issue13103] copy of an asyncore dispatcher causes infinite recursion

Giampaolo Rodola' added the comment: IMO, patch should only be applied to Python 3.2. For 3.3 we finally have the chance to get rid of the dispatcher.__getattr__ aberration (see issue 8483) so I say let's just remove it and fix this issue as a consequence. --

[issue13103] copy of an asyncore dispatcher causes infinite recursion

Xavier de Gaye added the comment: The infinite recursion occurs also when running python 3.2 with the extension modules copy, copyreg and asyncore from python 3.1. So it seems this regression is not caused by a modification in these modules. Anyway, the bug is in asyncore. The attached patch fi
