Due to an ftp server issue, my python script sometimes hangs whilst downloading, unable to receive any more data. Is there any way that I could have python check, maybe through a thread or something, whether it has hanged (or just, if it's still active after 10 seconds, stop it?). I have looked at threading but there does not seem to be a stop method on threading, which is a problem. Could the lower level thread module be a solution?
No. There are a great many issues which arise when trying to forcibly terminate a thread. Python doesn't expose this functionality because most platforms don't provide it in a safe or reliable way.
You could give Twisted's FTP client a try. Since it isn't blocking, you don't need to use threads, so it's easy to have a timeout.
You could also explore solutions based on signal.alarm(). A single- threaded signal-based solution has some issues as well, but not nearly as many as a thread-based solution.
