STINNER Victor <victor.stin...@haypocalc.com> added the comment: This issue comes from sandbox, not from ctypes.
Using sandbox, execv() C function doesn't close files with FD_CLOEXEC flag if the child program is a static program. test_ctypes hangs on find_library() in subprocess.Popen._execute_child(): - create a pipe for the child exception (if any) - fork - the parent reads this pipe - the child calls exec() - exec() closes the pipe and the parent continues its work - etc. find_library() runs "ldconfig -p" in a subprocess, and so everything hangs on "the parent reads this pipe" because "exec() closes the pipe and the parent continues its work" doesn't occur. ---------- Added file: http://bugs.python.org/file21767/sandbox_exec_bug.c _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11915> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
