> It seems like self.stdout.read() hangs even after the child process > has been killed. This is an issue when the standard handles are inherited or duplicated to a grandchild process, and so on. In the case of Popen(sys.executable), the system is duplicating the standard handles implicitly because sys.executable is a console process (assuming it's python[_d].exe), among other criteria. An additional reference on the write side prevents the pipe from closing. fh.read() in the grandparent won't return as long as there's a writer that could potentially write more data. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37531> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
