This page describes some limitations with using the local development server
(dev_appserver
) to test push queues in your application. In most
respects, you set up your queues and tasks just as you would to run them in the
App Engine production environment, but there are some differences:
- The development server doesn't respect the
rate
andbucket-size
attributes of your queues. As a result, tasks are executed as close to their ETA as possible. Setting a rate of0
doesn't prevent tasks from being executed automatically. - The development server doesn't preserve queue state across restarts.
To prevent push tasks from running in the development server at all, use the following command:
python2 DEVAPPSERVER_ROOT/google_appengine/dev_appserver.py --enable_task_running no
Replace DEVAPPSERVER_ROOT with the path to the folder where you
extract the archived version of devapp_server.py
. For more information about
downloading and using the archived version of dev_appserver.py
, see Using the local development server.
