New submission from David Jones: This is probably related to #21913, but more specifically concerns the documentation. I have a sub process of a larger program that handles a SIGTERM sent by the main process for a clean shutdown. However, if I launch a parallel task in the sub process, via multiprocessing.Pool.imap_unordered, all signals are blocked until pool finishes running the task. If this isn't going to be fixed, then it ought to at least be clearly documented. It took a very long time to diagnose this problem. It requires a programmer to understand the underlying implementation of a high-level construct, thus defeating the purpose of using a high level construct. Also, is there a way to work around this? ---------- assignee: docs@python components: Documentation messages: 253678 nosy: djones, docs@python priority: normal severity: normal status: open title: multiprocessing pool blocks SIGTERM from being handled type: behavior versions: Python 2.7 _______________________________________ Python tracker http://bugs.python.org/issue25511 _______________________________________
