Antoine Pitrou added the comment: Ok, I can now reproduce with setswitchinterval(). Here is a patch. There was a race between putting the new module in sys.modules and setting its __initializing__ attribute, so now __initializing__ is set before putting the module in sys.modules.
Also, there was another race when retrieving a module lock from the locks dict (the weakref could be destroyed between the __contains__ test and the actual fetch). ---------- keywords: +patch nosy: +georg.brandl priority: normal -> release blocker stage: -> patch review Added file: http://bugs.python.org/file27019/importrace.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15781> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
