1818589 - [imap-js] mailnews.imap.jsmodule=true duplicates Trash folder for Gmail

Status: RESOLVED FIXED

(MailNews Core :: Networking: IMAP, defect)

Description

[Sören Hentzschel]

Attachment: mailnews.imap.jsmodule=false

With mailnews.imap.jsmodule=true the trash folder for Gmail is duplicated. If you remove it via the Gmail web interface it is recreated by Thunderbird the next time you start Thunderbird.

With mailnews.imap.jsmodule=false it doesn't happen.

Tested with Thunderbird Daily 112.0a1 (2023-02-23) on macOS 13.2.

After initial gmail setup in a fresh profile, I get the [Gmail] folder showing. This indicates with imap-js we're not at that point realizing it's a gmail server. https://searchfox.org/comm-central/rev/35bfdf5fb8a89112a955dfb8d26ecf8cd1ae0719/mailnews/imap/src/nsImapIncomingServer.cpp#2043
After restart the [Gmail] is (not showing anymore) though, but at that point the Trash folder was already created at the root.

While the Gmail case is fixed now the folders (not only the trash folder) of my other mail accounts are duplicated. And the duplicated folders are subfolders of the inbox for unknown reasons.

@Magnus: Please see above.

With which daily did that happen? Could it rather be from bug 1816350?
Please check a webmail version and make sure any server side folders aren't actually there - for whatever reason or bug. Also the folder subscriptions so see if there's any clues there, like you'd have had those folders but they were previously unsubscribed(?). It could be better to investigate this in a new bug, with a protocol log attached.

It happened with the Daily from 2023-02-26 and I didn't test imap-js between the original bug report and my last comment. Regarding your other question / notices I have to investigate but I don't have enough time right now. I'll set a needinfo? request for myself so that I won't forget it and I will file a new bug once I know more.

You were right. According to mozregression it's a regression from bug 1816350. I filed bug 1819186.
