New submission from Thomas Moreau: The design of ProcessPoolExecutor contains some possible race conditions that may freeze the interpreter due to deadlocks. This is notably the case with pickling and unpickling errors for a submitted job and returned results. This makes it hard to reuse a launched executor.
We propose in the joint PR to fix some of those situations to make the ProcessPoolExecutor more robust to failure in the different threads and worker. ---------- components: Library (Lib) messages: 291224 nosy: tomMoral priority: normal pull_requests: 1180 severity: normal status: open title: Deadlocks in `concurrent.futures.ProcessPoolExecutor` type: behavior _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue30006> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
