Deleted messages still shown

[MarcusWolschon]

Server: Courier-IMAP

RoundCube often shows messages that are already deleted
in a folder.
Opening such a message shows an empty body.
Such ghost-messages cannot be deleted or moved.

This is NOT a Duplicate of #1485443 .
#1485443 is about opening a message that has been
moved via another client.

This is about LISTING messages that are no longer
there when opening a folder.

[alec]

Do you have enable_caching=true or not?

[MarcusWolschon]

enable caching of messages and mailbox data in the local database.
this is recommended if the IMAP server does not run on the same machine
$rcmail_configenable_caching? = TRUE;

lifetime of message cache
possible units: s, m, h, d, w
$rcmail_configmessage_cache_lifetime? = '10d';

[alec]

So, how you delete those messages? Maybe you're talking about such scenario: ​http://lists.roundcube.net/mail-archive/dev/2009-09/0000059.html

"and if one polls folder state between second and third operations are run"

No, the deleted messages are shown for DAYS at a time. I guess
folder-state is polled regularly. At least each time I open a folder.

Sometime the ghost-messages are gone when a real message in the same folder
gets deleted or moved via RoundCube.
Sometimes they even re-appear when opening the folder again.

You are talking about "marked as deleted (flag_for_deletion option), but not deleted" messages? Do you use other imap client? This maybe some misunderstanding of imap protocol, not a bug.

[MarcusWolschon]

I use many clients on that account.
Thunderbird, Roundcube, Flexmail on Windows Mobile, ...

The messages are only shown in RoundCube, not in any other client
and are not marked in any special way that would indicate a deleted-flag
(such as being greyed).

Anything I can do to gather information for debugging when it happens?

(It has about 50 folders and multiple gigabytes of messages. Roundcube runs
in another VM on the same host as the Courier-MTA -suite)

[alec]

So it must be a caching issue maybe not duplicate but related to #1485443. Probably those message were removed by other imap client, but Roundcube cache is out of sync.

[MarcusWolschon]

I guess something like that.

Disabling caching on an account of that size does not sound like
a good workaround. (Opening the "sent"-folder to search for something
already takes eons.)

[59395e7e] may fix your issue. Make messages table empty and do some tests with patch applied.

[MarcusWolschon]

I applied the patch.

I'll let you know if it happens again.

Thanks :)

[alec]

Then I close the ticket. Reopen if needed.

[MarcusWolschon]

Sorry,
it still happens.
I just had 5 such messages.

[alec]

Any new errors in log? What version are you running now? Did you remove messages table contents after update?

[alec]

No feedback.
