How to monitor Python files for changes?

Question

I want to restart my Python web application, if code gets changed. But there could be a large number of files that could be changed, since files in imported modules could change ...

How to get the actual file names from imported packages / modules?

How can modified Python files be detected efficiently? Is there a library to do that?

Answer 1

Shameless plug. There's also http://github.com/gorakhargosh/watchdog that I'm working on to do exactly this.

HTH.

Answer 2

gamin is another option which is slightly less Linux-specific.
