This is a race condition. The child has closed its -file descriptor, but has not yet fully exited before Pexpect's -:meth:`~pexpect.spawn.isalive` executes. Addings a slight delay before the -:meth:`~pexpect.spawn.isalive` call will help. For example:: - - child = pexpect.spawn('ls') - child.expect(pexpect.EOF) - time.sleep(0.1) - print child.isalive() - Truncated output just before child exits ---------------------------------------- |
