New submission from STINNER Victor: Hi,
During the development of Python 3.4, I tried to emit warnings if a file is destroyed without being explicitly closed. The warnings were not emited in threads during Python finalization. Here are related changes: - Issue #19421: "FileIO destructor imports indirectly the io module at exit" - Issue #19424: "_warnings: patch to avoid conversions from/to UTF-8" - Issue #19442: "Python crashes when a warning is emitted during shutdown" - Change in Python shutdown: issue #19466 "Clear state of threads earlier in Python shutdown" - Regression => issue #20526 The change #19466 had to be reverted a few days before the release of Python 3.4.0 because it caused the regression #20526. I'm still not convinced that #20526 was a new bug. IMO the bug still exists, but it is just less likely without the change #19466. There is still something wrong in Python finalization, so I open this issue to rework it. The goal is to get warnings in test_4_daemon_threads() of test_threading. I attached the test as a Python script. ---------- files: test_4_daemon_threads.py messages: 220804 nosy: benjamin.peterson, haypo priority: normal severity: normal status: open title: Rework Python finalization versions: Python 3.5 Added file: http://bugs.python.org/file35669/test_4_daemon_threads.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21788> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
