How to get the App Engine SDK to track file changes in directories added via sys.path?

Question

I am currently experiencing an issue with the Google AppEngine SDK where directories added using sys.path don't have their changes recognized by the SDK. Requiring the SDK be restarted in order for the modified files to have any effect.

This is particularly a problem with frameworks that make use of sys.path, such as tipfy.

Answer 1

I've been dealing with file monitoring for some time and wrote a library to do this. Hence a shameless plug:

Write a wrapper script around the dev_appserver module entry point to restart it using a library like: https://github.com/gorakhargosh/watchdog

or the nosy script at https://github.com/gorakhargosh/watchdog/blob/master/scripts/nosy.py

HTH.
