Answer 1

You have 60 seconds to complete a front-end request on Google App Engine. Locally however, that restriction doesn't seem to stick.

Your only options for longer processing are task queues (10 minute deadline) and backends (indefinite).

Answer 2

I too was experiencing this type of issue. In order to solve it, I had to increase the timeout for HTTP requests as well as move to a Queue.

I submitted a pull request to the Google Mirror API Python example, but it got rejected to keep things "simple".

You can checkout my diff at https://github.com/JessieAMorris/mirror-quickstart-python/commit/b67c0ecdf83207b0c3b596173c95a53804b23525.

Basically, the synopsis is:

1. Move processing to a queue
2. import urlfetch and httplib2

3. Increase the timeouts for urlfetch and httplib2 like so:

   urlfetch.set_default_fetch_deadline(45)
   httplib2.Http(timeout=45) 
   

With those changes in place, I don't get timeouts any more.
