Im writing a twitter app. It accepts commands as Direct Messages, so i
have setup a third party cronjob service to invoke a handler that
processes DMs at regular intervals. I have a Model 'Info' that has
just one entry, it stores some common data which are used in many
places in the App(in this case, the time when the messages were
processed recently). The general pattern of my handler is like this:
msgs = api.GetDirectMessages(since = info.msg_polled)
if not msgs:
return
logging.info('Processing Messages since %s ' % str(info.msg_polled))
for msg in msgs:
...process commands...
logging.info('Processed Message :- @%s : %s' %
(msg.sender_screen_name, msg.text))
info.msg_polled = datetime.datetime.now()
info.put()
But sometimes i get logs like this :
I 03-30 07:50AM 10.973
Processing Messages since Sun, 29 Mar 2009 11:41:59 GMT
I 03-30 07:50AM 11.122
Processed Message :- @foo : Foo_Bar
-------------------------------------------------------
I 03-30 07:46AM 08.014
Processing Messages since Sun, 29 Mar 2009 11:41:59 GMT
I 03-30 07:46AM 08.130
Processed Message :- @foo : Foo_Bar
Here, it seems that info is not getting commited to the database. The
message is processed multiple number of times, sometimes upto 10+
times before the msg_polled value changes. But i am not getting any
Datastore exceptions. This happens only once in a while.
Any help is appreciated.
