Description jacob.becker 2016-01-25 21:51:33 UTC
while talking to a cyrus 2.5 imap server akonadi_imap_resource constantly fails to gather metadata.
akonadi_imap_resource_1(15616) RetrieveCollectionMetadataTask::onGetMetaDataDone: Get metadata failed:  "GetMetaData fehlgeschlagen, die Serverantwort lautet: A000103 BAD Error in IMAP command GETMETADATA: Value 1/1 of DEPTH is not numeric and positive or infinity . ( RFC 5464 Section 4.2.2 ) "

this messages can easily seen if akonadiserver ist startet or restartet in a terminal.



Reproducible: Always

Steps to Reproduce:
1. start terminal
2. akonadictl restart (inside the terminal)


Actual Results:  
dozens of 
" akonadi_imap_resource_1(15616) RetrieveCollectionMetadataTask::onGetMetaDataDone: Get metadata failed: ..."
are shown.

Expected Results:  
the imap command GETMETADATA should be used right

i can see no directly impact of imap functionality in akonadi. This _could_ be a cosmetical thing.
Comment 1 Alexander 2017-02-07 17:30:12 UTC
Same here, KDE Applications 16.12.1 on Tumbleweed, IMAP-Server is secureimap.t-online.de . 

Getting hundreds of messages like:

org.kde.pim.imapresource: Get metadata failed:  "GetMetaData fehlgeschlagen, die Serverantwort lautet: A000091 BAD Error in IMAP command GETMETADATA: Value 1/1 of DEPTH is not numeric and positive or infinity . ( RFC 5464 Section 4.2.2 ) ( 0.000 + 0.000 secs ) . "

I'm not sure, whether this is the cause, but I can't delete emails locally!
Comment 2 Daniel Vrátil 2017-02-23 17:57:17 UTC
Could you please run the following in terminal:

export KIMAP_LOGFILE=/tmp/kimap.log
akonadictl restart


Then reproduce the issue again (wait until you see the error in terminal). After that look into /tmp folder, you should see several files starting with kimap.log - find the one that contains the error line and paste it here. Please also include a few (5 or so) lines above the error. If there are any sensitive information (folder names for instance), you can sanitize them.

Done as you suggested + ctrl-l in kmail to fetch emails.

Thanks for the update.

Hi,

thanks for the data. Looks like you only uploaded content of one of the files, there should be (at least) two file and unfortunately, the second one is the one I really need (sorry if it wasn't clear from my initial request). Could you please check and also post content of the second file? If the file is too large, just scroll towards the end to find likes like "A000025 BAD Error in IMAP command GETMETADATA" so you can only paste the last ~10 lines around that error line. Thanks a lot.

Comment 7 Daniel Vrátil 2017-03-20 23:04:26 UTC
Thanks. From the logs, it's visible that we *do* adhere to the RFC (DEPTH infinity), so it's likely a bug on the server side.

You mentioned Cyrus 2.5, but the only place where I could find the error message you are getting is in an old metadata plugin for Dovecot [0]. Now I suspect that quoting the infinity keyword might make it work, but I'm hesitant to implement it as it might break other IMAP servers.

Dovecot? No, not as far as I know. I'm getting this message from the servers of the german telekom, the webinterface is email.t-online.de .
Comment 9 Daniel Vrátil 2017-04-18 22:54:14 UTC
Hi,

I registered an email account on t-online.de and I can reproduce the error. They don't mention which IMAP implementation they actually use, so it can be anything. But since the error message you get matches exactly the one in the dovecot plugin I mentioned in comment #7, I strongly suspect that is what they use.

In any case, not even quoting the "infinity" keyword seems to work.

I'm afraid that all you can do is to open a ticket with t-online.de support and tell them their IMAP implementation is broken.

Feel free to provide the information above in the support ticket.

I'm closing this as "invalid", because it's a provider issue and not a KIMAP/Akonadi IMAP issue. Sorry we can't be more helpful here.

Yes, you are right. German Telekom announced an update "soon", which is expected to erease the bug. And they seem to be using dovecot. Clever of you!

I'll report as soon as the error vanishes.
