1795001 - Thunderbird 102.3.3 shows internal directories "cur", and "tmp" as folders in any folder with maildir

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Peter Hunkeler]

Attachment: Thunderbird_cur_tmp_folder_1.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:105.0) Gecko/20100101 Firefox/105.0

Steps to reproduce:

This is Thunderbird 102.3.2, and 102.3.3 on windows 10 21H2.

I recently migrated from old MBOX to new MAILDIR format at TB level 102.3.2. I did this on two PCs. Everything worked fine so far. Mails are stored as individual files in subdirectories "cur", and possibly in "tmp". Those are internal folders and they shall not be and are not shown in the frontend folder list. This is fine with TB 102.3.2

I updated one PC to TB 102.3.3 today and TB now shows the internal folders "cur", and "tmp" in each and every folder in the frontend, even in special folders like inbox, sent, trash, etc.

Actual results:

I updated one PC to TB 102.3.3 today and TB now shows the internal folders "cur", and "tmp" in each and every folder in the frontend, even in special folders like inbox, sent, trash, etc.

Expected results:

Internal folders "cur", and "tmp" must not be shown in the frontend folder pane.

Forgot to expolicitly mention that I verified that TB 102.3.2 still correctly does not show folders "cur", and "tmp".

I just recognized that there are "cur.msf", and "tmp.msf" files in some directories in TB 102.3.3. I also recognize that there now is a "subdirectory" directory (xyz.sbd) for each and every directory I have under the mail account, no matter if there are or aren't any real subdirectories. In those false subdirectories, I see two directories ("cur", and "tmp") and also an index file "cur.msf", and "tmp.msf".

Two more information:

• Firstly, those false subdirectries, and the display of the "cur", and "tmp" directories seems to be limited to top level directories, only. I do have a couple of directories with subdirectires (one and two levels). Non of those shows "cur", or "tmp".
• Secondly, I created another top level subdirectory, copyied a message into it, close TB, and restarted twice. The false behaviour is ont seen so far.

https://hg.mozilla.org/releases/comm-esr102/pushloghtml?fromchange=THUNDERBIRD_102_3_2_RELEASE&tochange=THUNDERBIRD_102_3_3_RELEASE - I don't see anything that could have caused that

Thank you for taking the time to investigate this. I had removed all those folders and have not seen it happen again.
Shall I mark this as resolved, and would "WONTFIX" be the right resolve reason?
