Body
Our app is deployed on the Google App Engine, Python runtime (2.7) and is consuming the Drive API. More and more it catches <code>HTTPException</code> because of an exceeded deadline, on different endpoints (Drive, OAuth, etc.) We have implemented an exponential back-off mechanism with 5 tries. Our app is more and more reaching this limit (this morning for example we had a lot of these exceptions). What could be the origin of this issues? Is it possible to increase the timeout delay? Thanks for your help. Here's a full stacktrace (OAuth2 API): <pre><code>2013-06-07 21:11:10,851 ERROR An error occurred : Deadline exceeded while waiting for HTTP response from URL: https://accounts.google.com/o/oauth2/token Traceback (most recent call last): File "/python27_runtime/python27_lib/versions/third_party/webapp2-2.3/webapp2.py", line 545, in dispatch return method(*args, **kwargs) File "/base/data/home/apps/s~unishared-gae/production.367909734400765242/main.py", line 733, in get creds = self.GetCodeCredentials() or self.GetSessionCredentials() File "/base/data/home/apps/s~unishared-gae/production.367909734400765242/main.py", line 301, in GetCodeCredentials creds = oauth_flow.step2_exchange(code) File "lib/oauth2client/util.py", line 128, in positional_wrapper return wrapped(*args, **kwargs) File "lib/oauth2client/client.py", line 1283, in step2_exchange headers=headers) File "lib/httplib2/__init__.py", line 1570, in request (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey) File "lib/httplib2/__init__.py", line 1317, in _request (response, content) = self._conn_request(conn, request_uri, method, body, headers) File "lib/httplib2/__init__.py", line 1286, in _conn_request response = conn.getresponse() File "/python27_runtime/python27_dist/lib/python2.7/httplib.py", line 500, in getresponse raise HTTPException(str(e)) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
