Ever since the 1.7.6 dev_appserver (aka dev_appserver2) upgrade, I see multiprocessing for requests. That is, if I define a simple app like this:
import logging import time from google.appengine.api import taskqueue from google.appengine.ext import webapp class MyTaskHandler(webapp.RequestHandler): def post(self): logging.info("howdy, this is a tasky!") time.sleep(5) class MyHandler(webapp.RequestHandler): def get(self): logging.info("howdy, this is test!") for i in range(20): taskqueue.add(url="/tasky") application = webapp.WSGIApplication([("/test", MyHandler), ("/tasky", MyTaskHandler)]) and then run a zillion *curl http://localhost:8080/test* request simultaneously, I can see multiple instances created, they run in parallel, the new admin interfaces shows them to me, it's just like it runs in the sky. That's great! But in the code, above, I'm also creating 20 tasks that run on /tasky for each hit to /test. I can see those enqueued on the default queue. Because of my sleep, they take a few seconds to run. But they're getting run serially. So it takes ~100s to run those 20 tasks, rather than 5s. Even if I go into the admin interface and hit the "Run Now" button on each one, they still are pulled off the queue serially. One "lucky" instance handles all of the task queue request. That's not so great, because it's making local runs of our test suite take a lot longer than they do in the sky. *How do I tell dev_appserver to run those tasks in parallel?* If this isn't possible, can someone help me understand why? I can easily POST directly to /tasky, and get the effect I want I thought multiprocessing support was a design goal for dev_appserver2 - why isn't taskqueue doing this for me?
