1617518 - After creating a search folder for unread news and feeds the folder is not displayed maildir only

Status: UNCONFIRMED

(Thunderbird :: Search, defect)

Description

[iii_iii]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:73.0) Gecko/20100101 Firefox/73.0

Steps to reproduce:

I created a new thunderbird profile. I changed the configuration to store messages with each message in its own file. I added a gmail account. I added a news and feeds rss account. I searched news feeds for unread articles and then saved the result as a search folder. I looked at the first unread article. I exited thunderbird and relaunched it.

Actual results:

The unread search folder does not appear.

Expected results:

There should be a folder called unread which gets populated with the unread news articles (status isn't read).

This has worked before but it maybe related to the setting to store emails each email in its own file, although I cannot see why.

find .thunderbird/ -print|grep -i unread
.thunderbird/femxw20l.default-release/Mail/Feeds/unread.msf

thunderbird -v
Thunderbird 68.4.1

I have verified that this only occurs when the option to store each article in its own file is selected (maildir). I did this by creating two profiles, one with maildir, one without, and then importing the feeds into each. After exiting and restarting, only the profile with maildir lost the unread search folder.

I'm pretty sure this is related to Bug 1533624 (even if not an exact duplicate).
It's an issue with local mail folders, as far as I can tell, but I think the feeds folders are local mail folders, so it's likely the same problem. That is, the issue occurred when the search folder itself was a local mail folder, rather than IMAP or News.

Over in Bug 1533624 I uploaded a patch which deal with this issue in local mail folders. If that lands it'd be worth checking to see if it fixes this bug too.

I notice something else which may be connected. If I select the Inbox folder which is imap, and enter a term in the search filter, and then switch to a mail and news search folder, the search term is cleared. However if I do it the other way around, select the mail and news search folder, and enter a search term in the search filter, then go to Inbox, the search term remains.

Also, (this is probably unrelated) entering the word 'one' in the search filter seems to match things which don't contain the word 'one', not even incidentally, like 'none'.
