This seems to be the recent change that causes the sudden badtoken errors Village pump
(technical)#How long does it take for a session timeout?
<https://en.wikipedia.org/w/index.php?title=Wikipedia:Village_pump_(technical)&oldid=649751259#How_long_does_it_take_for_a_session_timeout.3F>:
The test fetching the edit token at the beginning and
end of the run should certainly have not given you the same token each time; even fetching
two tokens one second apart should give you two different tokens (but both valid) since
the end of October. Since you got the same token hours apart, whatever you're using to
fetch the tokens is apparently caching them rather than fetching a new one the second
time.
Ideally, your bot should be able to attempt the edit,
and if it gets a badtoken error it should automatically fetch a fresh token and retry the
edit.
As for the time it takes, the configuration is
currently using the default of 1 hour for $wgObjectCacheSessionExpiry. I don't see any
recent changes to the timeout, but I do see there was this recent change to session
handling that probably made page views no longer reset the session timer. Anomieā 13:05, 3
