Description Luis Silva 2011-06-08 14:46:28 UTC

Version:           Git (master) (using KDE 4.6.3) 
OS:                Linux

Since commit 49852b34 the presence of pipethrough filters causes new messages to uncontrolably multiply . It seems that the newly filtered message is not replacing the recieved one and is being filtered again as if it was a new message. This then plays in loops. It might be relevant in this case that the program I am piping through (bogofilter) may be changing the messages.

Reproducible: Always

Steps to Reproduce:
Create a pipethrough filter and wait for new messages.

Actual Results:  
New messages are being filtered and duplicated. Then the duplicates are being filtered and duplicated, ... 'ad infinitum'

Expected Results:  
A new message should go through the filter chain and the end result written to the correct collection instead of the original.

OS: Linux (i686) release 2.6.38-9-generic
Compiler: cc

I am seeing this also in packages for Kubuntu Natty. I had to delete all Bogofilter filters.

Comment 2 Aldoo 2011-06-21 00:39:31 UTC

Seeing this too (OpenSuse 11.4).
But only one of my 4 cached IMAP accounts is affected by this bug.

Comment 3 Andre Woebbeking 2011-07-12 20:39:21 UTC

I also have this problem but for online IMAP accounts even if my "Bogofilter Check" had "from all but online IMAP accounts" checked.

Hej,

I committed multiple changes to master today which might fix this issue. Can you retest, please?

Ciao,
Tobias

Comment 7 Luis Silva 2011-09-18 11:59:24 UTC

I just recompiled master and it seems that the issue is solved. I'll give it a few more days trial and mark this bug as RESOLVED if nothing bad happens.
Thanks.

Messages are not being duplicated any more. However, the changes as a result of the pipethrough filters are not being propagated to the server (I am using disconnected IMAP). The result is that new messages that go through a pipethrough filter are being fetched and filtered at every sync, over and over again.

Ouuupppss! Last famous words...
There is indeed still message duplication, which may be related to the previous comment. However, I have one more observation. Duplication only seems to happen  for messages on an exchange/outlook based server. Could this issue be related to the particular server implementation?

Further information on this. Starting akonadi from a terminal I get the following output when clicking on one of the duplicate messages in kmail:

void Nepomuk::Query::QueryServiceClient::close() 
4721 FLAGS (\Seen)
akonadi_imap_resource_2(27513)/kdepimlibs (kimap) KIMAP::StoreJob::handleResponse: We asked for UID but the server didn't give it back, resultingFlags not stored.
