title: How do I display an exception's full stacktrace in Google App Engine's app log?
body: <p>While detaching an object from the datastore in a deployed app on Google App Engine, I'm getting an "failed to detach" exception that I can't reproduce on my development box. The detach operation is server-side, so the only information I have on it is the log of the exception in the app's log files. However, the stacktrace is elided: for example, the deepest internal exception ends with "... 36 more".</p>
  
  <p>How do I adjust the verbosity of the app's logging to include the full, non-elided stacktrace?</p>
