STINNER Victor <vstin...@python.org> added the comment:
A workaround is to use close_fds=False which is only safe if all code used in Python implements the PEP 446. This PEP mentions the FreeBSD issue, mentioning bpo-11284 with MAXFD=655,000: "The operation can be slow if MAXFD is large. For example, on a FreeBSD buildbot with MAXFD=655,000, the operation took 300 ms: see issue #11284: slow close file descriptors." Note: the subprocess module is now able to use posix_spawn() syscall, but it doesn't use it if close_fds=True, so it's outside the scope of this issue. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38061> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
