Carl Friedrich Bolz-Tereick pushed to branch branch/py3.7 at PyPy / pypy
Commits: 7dc1056e by Carl Friedrich Bolz-Tereick at 2020-04-09T22:14:04+02:00 fix bpo-31976: a race condition between BufferedWriter.close and .write, if the flush called by .close is taking a long time: write needs to check whether the file is closed *while* it is holding the lock. Otherwise the file can still be open at the beginning of the write method, but by the time the lock is acquired a bit later the file can have been closed in the meantime. Unfortunately I didn't manage to write an applevel test for this problem, but test_slow_close_from_thread() in the stdlib's test_io.py shows the problem. --HG-- branch : py3.7 - - - - - 1 changed file: - pypy/module/_io/interp_bufferedio.py View it on GitLab: https://foss.heptapod.net/pypy/pypy/commit/7dc1056eb8bb765cd82a5fd05e0957aa7310d1ae --- View it on GitLab: https://foss.heptapod.net/pypy/pypy/commit/7dc1056eb8bb765cd82a5fd05e0957aa7310d1ae You're receiving this email because of your account on foss.heptapod.net.
