TASK DESCRIPTION
My setup
--------
I am constantly listening to the recent changes channel with a python script
of the following form:
from pywikibot.comms import eventstreams
stream = eventstreams.EventStreams(streams='recentchange')
stream.register_filter(type='edit', wiki='dewiki')
while True:
change = next(stream)
# do stuff
After this script notified me about edits from multiple days ago on multiple
occasions, I started to monitor the difference between the timestamp of the
edit and the time, I retrieved the edit. With this, I was able to log the
following event.
Example
-------
The last restart of my service was on May 23th, 21:37 UTC. Until May 26th,
11:02 UTC, it seemed to work just fine and the delay stayed below the boundary
of 5min, I configured. Then, the eventstream jumped back in time and I
retrieved an edit from Mai 19th, 10:55 UTC. After this, it seemed to retrieve
all edits starting with this old one. On 13:04 UTC it was back on track and
retrieving up to date changes.
Workaround
----------
I could just restart the service as soon as I detect a highly delayed edit.
Is this a known issue? Or does anybody know if it is a pywikibot-problem or
if the mediawiki-api serves weird stuff?
Thanks in advance for your help.
