New submission from STINNER Victor <vstin...@redhat.com>:
test.support.fd_count() has two implementation: list /proc/self/fd/ on Linux and FreeBSD, or check all file descriptors from 0 and MAXFD. The problem is that the two implementation don't give the same result... List /proc/self/fd/ (used by default on Linux): vstinner@apu$ ./python -c 'from test.support import fd_count; print(fd_count())' 4 Check all FD (I modified fd_count() to force using this implementation): vstinner@apu$ ./python -c 'from test.support import fd_count; print(fd_count())' 3 On Linux and FreeBSD, listdir() opens internally a file descriptor to list the content of the /proc/self/fd/ directory. So the function should substract one to the result. Attached PR fixes the issue. ---------- components: Tests messages: 318734 nosy: pitrou, vstinner priority: normal severity: normal status: open versions: Python 2.7, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33773> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
