New submission from Grzegorz Grzywacz: as_complite generator keeps reference of all passed futures until StopIteration. It may lead to serious memory inefficiency.
Solution is to remove reference from lists and yield future ad-hoc. I have submitted patch and reproduce sample. I can create backport for older versions if needed. ---------- components: Library (Lib) files: reproduce.py messages: 266552 nosy: bquinlan, grzgrzgrz3 priority: normal severity: normal status: open title: concurrent.futures.as_completed() memory inefficiency type: resource usage versions: Python 3.2, Python 3.3, Python 3.4, Python 3.5, Python 3.6 Added file: http://bugs.python.org/file43037/reproduce.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27144> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
