Bug ID: 501754
Summary: Kmail ignores server errors when moving messages and
goes out of sync with the IMAP server
Classification: Applications
Product: kmail2
Version: 6.3.3
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kdepim-b...@kde.org
Reporter: jim+...@not-null.co.uk
Target Milestone: ---
SUMMARY
If a move operation is rejected by the IMAP server, kmail seems to ignore the
error and updates the local cache, causing it to go out of sync with the
server.
In my situation, I was attempting to move 6000 emails from my inbox to another
folder. According to akonadi console my IMAP server rejected this with "A000544
BAD parse error: maximum request size exceeded", however kmail still proceeded
with the move and made it appear successful. When I later refreshed my inbox,
kmail performed an extremely long full sync of the folder (with akonadi console
warning of a "detected inconsistency in local cache") which restored the
previously moved messages. A second copy of the messages still exists locally
in the folder I attempted to move them to, which kmail does not sync to the
server even when the folder is manually refreshed.
STEPS TO REPRODUCE
1. Attempt a move operation which the IMAP server rejects (e.g move thousands
of messages to another folder)
2. Observe kmail completing the move without errors
3. Refresh the source folder
OBSERVED RESULT
Kmail ignores the server error and goes out of sync with the server, making the
move appear successful until the source folder is refreshed. Once the refresh
completes, duplicate emails from the move remain in the destination folder.
EXPECTED RESULT
Kmail aborts a move if it fails on the server side, ideally with a message
explaining what happened.
