on macOS 14.3, testing using IMAP with TB release channel

  • 115.9.0 (build FR 20240314154241)
  • 115.10.0 (FR build 20240412173147)
    TB close all processes while quitting.
    Can't reproduce the bug.

Let's confirm this based on the number of reports.
That said, can't reproduce on linux. Tried 115.10 on windows as well and could not reproduce there either.

For those affected, try Help | Troubleshoot mode, and report back.

Bug 1862111 would seem like the most likely regressor (if it's from c-c). I'll create a try build with that backed out so people can try it out.

Can confirm on Windows 10 Pro Version 22H2 build 19045.4291, Thunderbird 115.10.0 (64-bit) and (32-bit) before fresh install/upgrade (to try to solve this).

The three lingering processes after closing Firefox:

Thunderbird can't be restarted as long as theses processes aren't manually ended in the task manager. Nothing visibly happens when trying to restart Thunderbird, but a new process is running:

Restart in Troubleshoot mode fails (not responding). After manually ending all Thunderbird processes and restarting, Thunderbird doesn't appear to be in Troubleshoot mode...

Of 3 machines I updated to 115.10.0 this morning, only one appears to almost systematically hang up on closing. All instances of Thunderbird access the same server (with different accounts), IMAPs + Submission, same (very few) add-ons.

Another duplicate in bug 1891370.

The 3 hung up processes stay for hours, not just some slow resolution/time out.

Try run: https://treeherder.mozilla.org/jobs?repo=try-comm-central&revision=84e958ebc67f55f36109e8a1817e62596bb78661.
Please try one of these builds to see if this works better:

Installed the Windows version provided above. Ran "C:\Program Files\Thunderbird Daily\thunderbird.exe" -P to select my existing profile. Could open and close Daily a few times without any hangups, no process lingering more than a few seconds in the Task Manager.

Tried again in Thunderbird release 115.10.0 and this time couldn't even close the Thunderbird window (Not Responding). Ended the processes in Task Manager, retrial, same behavior as before but could close the window.

(I did make a backup of my profile but still hope I didn't trash it, because of a few hours of activity missing.)

In my Yahoo IMAP account the solution was to uncheck "Empty Trash on Exit". That seems to be what's causing the hangup.

Yes, use it everyday. It just started in 115.10.0 like for everyone else. But interestingly, it's was happening in Windows 10, in Windows 7 it was still closing properly, even with that setting checked.

I tried to confirm this but couldn't. In Settings > Message Storage >, I tried to check/uncheck both 'Clean up ("Expunge") Inbox on Exit' and/or
'Empty Trash on Exit', and still had hangups in all cases.

Doesn't tell much though, as the hangups aren't consistently reproducible. It did seem like they were a lot less frequent when unchecking both.

Yup - this worked for me on win 10 latest.
... Now I wonder how to get back to regular TB (not the daily)?

Those test builds were not daily, but for the 115 branch.
In case you used another profile, to get the original, start with ´thunderbird.exe -P` to select profile. Also available through Help | Troubleshooting information | about:profiles.

That server settings, empty trash put OFF , seems help, then not run background when closes.
I also put off setting above that.

Hello,

We have tried to reproduce this issue using Windows 10, Windows 11 and macOS14 and did not succeed.

We tried to reproduce it with an IMAP and using 'Clean up ("Expunge") Inbox on Exit' and/or 'Empty Trash on Exit', options toggled ON/OFF.

Tested on:

115.9(20240314154241)
115.10(20240412173147)
124.0(20240312201328)
125.0b5(20240408161305)

Confirming that no server property modifications ('Clean trash on exit', etc.) on OSX did solve the issue.

Unfortunately, this build did not change anything for me - behavior is still the same.

I also did not read the thread completely and was surprised I had to recreate my profile, but that's no Biggie - only took 15 minutes to get everything back.

I was bummed though to go through this and see the exact same behavior. Also, as when I first reported this several months ago, unchecking "Empty trash on exit" makes no difference. (https://support.mozilla.org/en-US/questions/1441054?page=1)

For me at least 115.10.1 has resolved the issue. I can re-check "Empty trash on exit" and it's closing properly again. Maybe the differences some are having is based on what the email account is. Mine is Yahoo so it could be that gmail or others have separate issues.

Mine is a mix of Yahoo and GMail, but no POP accounts.

Hopefully they'll find it and fix it.

Confirming that this issue mainly seems to affect OSX builds. I couldn't reproduce the behaviour on neither Windows 10 nor Linux (up-to-date Arch), both Intel-based machines.

Has somebody with an Intel-based OSX machine ever verified this (wild hunch :-)? As mine is an M1-based MBA.

It's OS agnostic afaict. But there are certainly factors that cause some people or computers to have the issue and others not, for reason we don't understand.

Confirming that on Win 10 this build of 115.10.1 fixes shutdown issues on my home PC.

Thanks to all. This has been a very instructive (and rather inspirational) experience, since I first noticed and reported (my first time) this bug in the new 115.10.0 two days ago. Very impressive community success.

So far 115.10.1 seems to fix the problem on Apple Silicon running OSX 14.4.1. It would interesting what part of the delta between 115.10.0 and 115.10.1 caused this vanish, leading to a potential explanation when comparing this to the delta between 115.9 and 115.10. Unfortunately the core code repo of TB seems to require some serious learning curve when trying to check this out (in comparison to approaches like Github, etc.).

115.10.1 seems to fix it for me too, and I was one of the first to notice this bug. Running Win 11, Intel i9.

I've closed and re-opened multiple times, monitoring Task manager, and I have not yet seen the Thunderbird process move to the background.

I just noticed two new posts of the problem on SUMO:

Update: while this is still true, now I notice (with 115.10.1) that Thunderbird no longer checks for new mail while running. It will do it exactly once when it's started, but nothing further after that unless I shut it down and restart it.

Verified server settings for "check mail" are correct.

Make sure you have "Allow immediate server notifications when new messages arrive" turned on.

Hi, I was looking at the 'deleted' folder where there were only a few deleted messages from my last session. I then went to the deleted folder properties and pressed the 'Repair Folder' button and after a short delay there were now 150 about deleted messages, dating back about 4 days which was about when the problem started on my PC. I then exited from Thunderbird and tried to restart it - and it restarted normally without a problem. It appears that the problem could be a corrupt 'deleted' folder, which perhaps prevented the background processes from shutting down.

I think that Thunderbird is now working normally (touch wood). I'll update here if the problem reappears.

I hope this helps.

Probably more important to make sure "Check for new messages every X minutes" is set (default X = 10 minutes) since not all servers support "immediate" notification (i.e., imap IDLE).
Anyhow, don't see that this is related to this bug. If still not working, probably should be a new bug report.

Update: Tested this with 115.10.1 on win10 and emails come in OK with "check for new messages ..." time set to 10 minutes. The imap server doesn't support immediate notification (IDLE).

Gene notes in bug 1862111:

  1. Workaround when using 115.10.0 with "empty trash on exit" enabled, is to click on trash folder before shutdown.
  2. A fix is available for testing https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/VgCkdNgURC6vIJDADUqK6w/runs/0/artifacts/public/build/install/sea/target.installer.exe (build is based on comm-central)

Test results would be appreciated for #2 ... Anyone using beta or nightly builds can safely test it. If using 115 also shouldnt be a problem but you should back up your profile. And after testing, when starting your normal build, you may need to use --allow-downgrade on the command line on startup.

Re: comment 70:

I've updated the fix and made a try build based on 115.10.1. So to run this you won't need the --allow-downgrade command line option since this is still 115 with a patch. If you run this, Help/About will report it as Daily but with version 115.10.1.

There shouldn't be any functional difference than with standard 115.10.1. It just puts back in the change that was backed-out from broken 115.10.0 but without the hang on shutdown bug that left TB processes running in background.
The best test for this is to configure TB server settings to "expunge inbox on exit" or "empty trash on exit" or select both of them. Make sure these activities occur on shutdown and that the shutdown is complete (no TB processes still running after shutdown).
Note: "expunge inbox on exit" may be hard to verify that it really works without recording an IMAP log. Of course, empty trash on exit is pretty easy to verify.

FYI, here's the complete try build:
https://treeherder.mozilla.org/jobs?repo=try-comm-central&revision=8e9ef0128cada3982de27c37aa8758bfddc8f56a&selectedTaskRun=bXsAroz3QxWUFQ8CntXkcw.0

Note: If anyone needs a Debug build they are also available there by clicking on a green "B" and finding the installation file under "Artifacts and Debugging" down below.
However, for some reason the "Windows 2012 opt" build (32-bit windows) failed (indicated by red "B") due to a server error of some sort. However, the 32-bit debug Windows build worked OK (Windows 2012 debug) which is OK but might run a bit slower.

This version (115.10.1) seems to bring back a lot of older bugs, including the Inbox showing some number of unread emails when all are read, as well as deleting emails in the card view sometimes leaves empty (blank) cards.

Not sure if this should be entered as a new bug or not.

I have explained the reason for this bug , as reported in comment 0 above, at bug 1862111 comment 25.
I think this could be closed as FIXED since the offending code was backed out at comment 37.

115.10.1 only differs from 115.10.0 by backing out some problem code shown in the link at comment 37. So that won't cause other problems you see.
I'm not sure what other changes went into 115.10.0 but Wayne shows a list of changes in comment 3 above. I don't know if this is all the changes between the 115.9.0 and 115.10.0 but I suspect it is.

Anyhow, if you are seeing other new or recurring bugs, they should not be put into this bug report.

Re: comment 70:

I've updated the fix and made a try build based on 115.10.1. So to run this you won't need the --allow-downgrade command line option since this is still 115 with a patch. If you run this, Help/About will report it as Daily but with version 115.10.1.

Here's for windows64 optimized:
https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/c4sqNh6sTImlyx3cVcLCJA/runs/0/artifacts/public/build/install/sea/target.installer.exe

I've successfully tried this build. Sent to myself a few messages and deleted them so the trash folder wouldn't be empty. Checked that for my IMAPs account, both 'Clean up ("Expunge") Inbox on Exit' and 'Empty Trash on Exit' were checked. Closed Thunderbird Daily and checked that there was no processes left behind.

Will continue to use that build and report back if there happen any trouble in normal use.

(FWIW I was using the last stable 115.10.1 release for a few days before that without any trouble too.)

Nothing new to report using this build. The bug never happened again, same settings as reported before.
