Is that in some error branch of Py_Initialize() ? Otherwise I don't see how the modules could get garbage-collected. >> I'm not exactly sure which global state you are referring to.

While I could add some tricks to have the cache dictionary stay alive even after the globals were set to None, I doubt that this will really fix the problem. The encoding package relies on the import mechanism, the codecs module and the _codecs builtin module. Any of these could fail to work depending on the order in which the modules get GCed. There's a reason why things in Py_Finalize() are as carefully ordered :-) Perhaps we need to apply some reordering to the steps in Py_Initialize() ?! -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, Jan 19 2007) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ ::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,FreeBSD for free ! :::: _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
