[Bug 1332120] Re: panic error while backup mailboxes with doveadm backup
Lars, As I explained above, I don't think this bug can make any progress without the input of the upstream patch authors. The fixes look very complex to cherry-pick and so risk regression and/or failure to fix the problem for us if we try to backport the fix from Trusty. It needs someone already familiar with the code to advise us or for a skilled developer to spend time becoming familiar with the code. I don't expect the Ubuntu Server Team to make any further progress on this. Volunteers are welcome to prepare a backport, though note that the more complex the backport is, the less likely it is that an Ubuntu developer will be satisfied that it presents a sufficiently low risk of regression of regression to existing 14.04 dovecot users. Note that this bug is believed fixed in Wily (15.10) , so it is just the Trusty (14.04) backport of the fix that we're talking about here. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to dovecot in Ubuntu. https://bugs.launchpad.net/bugs/1332120 Title: panic error while backup mailboxes with doveadm backup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1332120/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Hi Robie, can you tell me good news? Is there some progress? I'm sorry I couldn't help further.

[Bug 1332120] Re: panic error while backup mailboxes with doveadm backup
Further to the patch you proposed there was a subsequent commit "doveadm backup: Fix to handling mailbox deletions." (http://hg.dovecot.org/dovecot-2.2/rev/57a490780b1e) which wipes out the lines changed. And then a further commit "doveadm backup: Another attempt at fixing assert-crashes when deleting mailboxes." (http://hg.dovecot.org/dovecot-2.2/rev/20462a116704) after that. So it isn't clear to me that the patch you've proposed fixes the issue. There are a bunch of related fixes after those two commits that seem related too (http://hg.dovecot.org/dovecot-2.2/log/tip/src/doveadm/dsync /dsync-mailbox-tree-sync.c) So I don't think this is trivial to cherry-pick into 14.04 at all. To drive this forward I think we need a comprehensively analysed fix for the issue that we can be confident with. I think we need Timo's input here. I'm going to remove this from my list of bugs that can be tackled immediately. If someone affected can help us arrive at a patch that comprehensively fixes this problem, then please do. I'll stay subscribed to this bug. Version 1:2.2.18-2ubuntu2 that is in Wily is subsequent to the patch you proposed, so I'm going to mark this issue fixed in Wily for now, but leaving the task for Trusty open. If this is incorrect, please explain how you have verified this and change the bug status back to New. ** Tags removed: bitesize server-next ** Changed in: dovecot (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1332120 Title: panic error while backup mailboxes with doveadm backup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dovecot/+bug/1332120/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1332120] Re: panic error while backup mailboxes with doveadm backup
Hi there! Is there someone reading this report? The fix is included already. It is a server critical bug, because it influences the imap backup functionality. Please give it a chance. I'm manually repairing the imap backup every time a user deletes an imap folder. Please. It is the LTS server release!

Is there anyone working on this report? This isn't only a bug report but also a fix report. And the fix isn't from someone strange on the net but the original author of dovecot. So _please_ fix this. This packet is essential for an imap mail server.
