Hello,
I updated to the latest version a few minutes ago. At first view I can confirm that this issue seems to be solved. The real test starts tomorrow. :)
Thank you,

Hello,
after some testing I can not confirm. Sorry, but the error is not fixed. Thunderbird is still reloading all headers when the user changes the folder.
In case of fast folder changing, the folders seems to be empty. After switching back to another and back to the first one, the headers will load again.

Installed version is: 8.3.0~999 on Debian 8.

Update: I installed core-8.4.0~0_10 but the problem still persists. In this situation Kopano is not usable.

Steps to reproduce:

Goto INBOX -> Mails are visible
Goto SENT -> Mails are visible (mostly)
Incoming new Mail.
Goto INBOX -> Only the new mail is visible, all other mails are “away”.
Go back to SENT and then again to INBOX: Thunderbird reloads all Headers and the new Mail isn’t visible.

Greetings.

Sounds like your issue is then not related to the imap optimisations at all. do you have any error messages or even deadlocks in your kopano-server logging?

robgnu

I’ve checked the logfile and could’n find any deadlocks. Now I changed the logging level to debug.
There are no error-messages at all. Only messages like

Mon Mar  6 12:10:03 2017: [debug  ] Accepted incoming connection from file:///var/run/kopano/server.sock
Mon Mar  6 12:10:03 2017: [debug  ] Previous message logged 19 times

Mon Mar  6 12:10:04 2017: [debug  ] Accepted incoming connection from 127.0.0.1

What else can I do to help debugging?

My Thunderbird is also affected, I tried multiple versions of Thunderbird since I initially thought using a beta version of Thunderbird is the problem. Clicking “Get Messages” changes what Thunderbird displays in the INBOX Folder. The Problem usually starts occuring when new mail arrived: I see a folder with 20-30 mails, and the second the new mail arrived it shows only the one new mail.

I installed “EM Client” as an alternative to Thunderbird and even though this client uses IMAP as well it does not seem to be affected.

Hi

I found the commit that caused the trouble. I have submitted revertion, let us hope it will make the nightly tomorrow.

If you want to revert it your self and compile the commit is: 611536a8fc36186b74804a367ce54fc420b86de4

Thanks for your patience!

Ok, I can report, that I’ve downgraded to version core-8.3.0~694_76.1-Debian_8.0-amd64 and started the kopanao-server with

ExecStart=/usr/sbin/kopano-server -F --ignore-database-version-conflict

to force the downgrade. I confirm (again) on this version the IMAP is working without problems. The IMAP is broken in version 8-3-0-788 and later. But I can’t say, which version introduced the bug between 694 and 788.

Fix is now in kc-8.3.x, will ensure it will hit the master today, so it will get included in the nightly build.

Again, thanks for your patience.

I’ve just installed the new build and my quick initial tests seem to confirm that tonights build has indeed fixed the IMAP problem.
Let’s hope it stays this way.

robgnu

Hello. Thank you for this information. I will check in a few days when I’m back home. I will report if the problem is solved.
Thanks to the Kopano-Team.
