Review request for KDEPIM.


Summary
-------

Currently, if unable to determine the UID of a message after an APPEND or COPY command, we abort the task and leave the Akonadi item with an empty RID. During the next sync, the message we added to the server is discovered and downloaded, duplicating it locally. Items with empty RIDs are protected against deletion during a sync, since they are assumed to not be on the server yet. This is a safety feature, but gets in to the way of automatic recovery here.

So, this patch fixes this by assigning an arbitrary random RID in this case. Note that this only happens if all UID detection attempts fail, not if e.g. the actual APPEND or COPY failed. Assuming that those commands report errors correctly, this should be safe.


This addresses bugs 259214 and 264266.

Testing
-------

None, unfortunately, I cannot trigger this code path here since I have no access to a non-UIDPLUS server.


Thanks,

Volker
