323815 - News Files/Folders are not deleted on unsubscribe

Status: RESOLVED DUPLICATE of bug 314383

(MailNews Core :: Backend, defect)

Description

[Mark Banner (:standard8)]

1) Create a news server account & add some news groups.
2) Examine the profile and find the news group files.
3) Unsubscribe from one of the groups

Expected result:
News group file deleted.

Actual result:
News group file NOT deleted. Warning on console: 

WARNING: NS_ENSURE_TRUE(NS_SUCCEEDED(rv)) failed, file /opt/mozmaster/mozilla/mailnews/db/msgdb/src/nsMsgDatabase.cpp, line 167

4) Delete News server account

Expected result:
News group folder & associated files deleted.

Actual Result:
News group folder & associated files NOT deleted. No warning on console.

This is on today's trunk, but judging from the state of my profile folders (from some testing of news group subscriptions I did before) its been around for quite a while.

Duplicate of bug 128744, by way of the more explicit (for NNTP/News) bug 94967?

Be nice to see this fixed!

Possibly, lets see how it pans out ;-)

Here is an update of what I've just looked at: I've just checked nsMsgNewsFolder::Delete(), it deletes the news summary file (the .msf) but not the .dat file.

Do we create a folder if we are in offline mode - I haven't looked yet, but it would explain the other part of the Delete mechanism.

I'm guessing that once nsMsgNewsFolder::Delete() has been called something else is still retaining a link to the old news folder, and somehow recreates or re-saves the msf file.
