786155 - Delete - Undo leading to duplicates

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

I'm seeing a problem where if I Delete, then Undo, the message, and others in the same thread often get duplicated.   

This happened again just now, and I repaired the folder, and a few minutes later the same thng happened. 

I notice a number of other Delete/Undo bugs have been posted by others: Bug #349831 Bug #533513 Bug #539730 Bug #717422 - all marked Resolved WorksForMe or Incomplete, and I concur to having seen similar behaviors many times, all around the combination of Undo followed by Delete - something is unstable in that code. 

Note this it the first time I've caught it enought to get screenshots. Which I've attached - one shows how it looks in my Inbox, and the other how it looks on the server as viewed through another IMAP client (that I only opened up AFTER this problem happened, so that wasn't the cause).

so, Repair Folder gets rid of the duplicate??

Does it only happen with inbox?

Comment 3

yes - repair folder gets rid of them (but of course is painful as it loses all kinds of other info (like columns) and also seems to download the whole (200+Mb) mailbox again , 

I've only seen it on Inbox, so it might be limited to that - e.g. interaction between the transfer and the Inbox updating. BUT its only really Inbox where I do enough transfers (bug #782300) or delete/undo's to experience it.

See also Bug #719752 which seems to be almost the same thing

perhaps we should first sort out your bug #782300

Actually. more important would be to fix Bug #857465 - where delete / undo loses data. I'm not seeing bug #782300 any more but not using filters as much any more.

Mitra, does this still reproduce for you when using a current version?

Comment 8

I'm not seeing this exact bug, though I still see Bug #857465 

I *am* seeing very significant database issues. Often click on a listing only to see the content of a completely different message shown.  That may be a manifestation of a similar issue. 

Note ... moving message to a different folder, doing a "Repair Folder" and moving back works on that message. Doing a full Repair folder on the inbox takes many minutes and only seems to fix it overall for a day or so.  I don't know if its related, and since it can't be repeated havent posted the issue.
