Disabling Task Queue Retry in Google App Engine

Question

Is there a way to disable the retry options for tasks that failed? Its not possible to do this in queue.yaml

retry_parameters:
    task_retry_limit: 0

Is there any other option to disable retries?

I guess you have to fill bug report if it does not work for you, because docs say opposite: http://code.google.com/appengine/docs/python/config/queue.html#retry_parameters — Vladimir Mihailenco, Jan 09 '11 at 17:38
what do you mean with "it's not possible to do"? It does not work or 0 is not allowed (I checked the source and 0 seems allowed to me)? — systempuntoout, Jan 10 '11 at 14:16
This has been accepted as a bug and work started according to http://code.google.com/p/googleappengine/issues/detail?id=7423 — wodow, Mar 05 '13 at 16:46

If setting task_retry_limit to 0, you can try checking for the task queue header X-AppEngine-TaskRetryCount, and aborting if it's non-zero.

Setting task_retry_limit to zero appears to be allowed as of SDK version 1.7.5.

The following queue.yaml was accepted:

queue:
- name: default
  rate: 5/s
  retry_parameters:
    task_retry_limit: 0
    task_age_limit: 1s

However, it is not obeyed.

In the latest version - 1.4.3 it needs to be greater than zero

Trying to upload 0 gives you this...

Error 400: --- begin server output --- Invalid queue configuration. Task retry limit must be greater than zero. --- end server output ---
