[Kde-pim] ItemSync issues, further investigation

[David Faure]

So, I gather from the recent replies (thanks Christian and Dan) that all my problems come from the changes in ItemSync...
More debug output in ItemSync shows this:

Akonadi::ItemSync::slotResult: 103 "Multiple merge candidates, aborting"

[then it keeps going with more calls to slotTransactionResult, and then some readyForNextBatch like this]

akonadi_imap_resource_0(26958)/libakonadi Akonadi::ItemSyncPrivate::checkDone: readyForNextBatch 100
akonadi_imap_resource_0(26958)/libakonadi Akonadi::ItemSyncPrivate::checkDone: readyForNextBatch 100

and then suddenly this happens:

akonadi_imap_resource_0(26958) ImapResourceBase::startTask:
akonadi_imap_resource_0(26958) ResourceTask::start: Starting task RetrieveItemsTask(0x123cfb0)
ResourceTask::onSessionRequested: task RetrieveItemsTask(0x123cfb0) session request says 13 7 "Could not create another extra connection to the IMAP-server imap.gmx.com."
ResourceTask::onSessionRequested: Cancelling this request. Probably there is no more session available.

But, but, the item sync is not done, the emitResult in itemsync.cpp wasn't emitted.
However I found out why taskDone was called:

the ItemSync job gets this string from the akonadiserver:
"NO There is no transaction in progress"
which leads to a direct emitResult() in akonadi/job.cpp:65.

=>

1) Maybe this should be caught by ItemSync to abort everything else it's doing?

2) Why does the akonadiserver reply that? Because it stopped after "Multiple merge candidates, aborting"?
But then the comment in itemsync that says "let's keep going" (after the first error) is wrong?

3) What does "Multiple merge candidates, aborting" mean? I can reproduce this reliably by selecting my "archive" folder (5k emails).
