What should the behavior be if an exception is raised in a pool worker during bootstrapping / initialization function execution? I think an exception should be raised in the process owning the Pool, and in the fix I'm tinkering around with I just raise a RuntimeError currently. I can see an argument also for raising different exceptions (or having different behavior) for bootstrapping error vs init function, but implementation is more complicated. My current implementation simply creates a lock in _repopulate_pool_static, acquires it, and waits for the worker function to release it. By polling every 100ms I also detect if the process exited before releasing the lock in which case I raise a Runtime error. I just started testing this implementation, but I'll provide it for anyone else who wants to test / comment. ---------- Added file: https://bugs.python.org/file50230/pool.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43306> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
