[issue7707] multiprocess.Queue operations during import can lead to deadlocks
New submission from Alon Zakai thoughtc...@gmail.com: Creating a multiprocessing.Queue and operating on it while being imported can lead to a deadlock. The attached file will work if run directly (python test.py) but will hang if imported from the interpreter (import test).

Brett Cannon br...@python.org added the comment: Without looking at the multiprocessing code I am willing to guess that some code in that run() function is launching some code that runs in a thread that is performing an import, deadlocking on the import lock. Jesse, is that what could be happening? If so we should probably add a note to the multiprocessing docs to not do this sort of stuff, ala http://docs.python.org/library/threading.html#importing-in-threaded-code . -- assignee: - jnoller ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7707 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
