Sentry Crash Report:

Description Markus 2020-10-05 10:21:35 UTC 
SUMMARY
Running some remote ics calendars. In the past they updated automatically, but current it just stucks in InvalideCacheForCollection.

STEPS TO REPRODUCE
Reproducing is currently not possible, due to bug 425460.

OBSERVED RESULT
When I look in akonadi console in the task list of the resource it is always sitting in the current task "InvalideCacheForCollection". (With a "SyncAll" queued up but never executed.)

In the code I see that "InvalidateCacheJobPrivate::itemStoreResult" is calling "emitResult", but "ResourceScheduler::taskDone" or "ResourceScheduler::executeNext" is never called again.

SOFTWARE/OS VERSIONS
Linux: 5.8
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0
KDE Apps Version: 20.08.1
Qt Version: 5.15.1
Comment 1 Markus 2020-10-05 14:14:23 UTC 
I recover (for the moment) by putting the agent offline, restart it, abort all activities, put it online again and manually start synchronize all.

Restarting the agent again, will block in InvalideCacheForCollection again, when the (ics) file changed: "The hash has changed."


I checked in resourcebase.cpp, the commit removed the connect of the result?

Reverting that bit makes InvalideCacheForCollection finish again.

Was it removed on purpose?
Comment 2 Laurent Montel 2020-10-05 14:35:16 UTC 
I added Dan as CC of this bug. As indeed it seems not logical to remove it.
But perhaps he has a reason for removing it
