303324 - Threading gets turned off whenever a mail folder's summary file gets rebuilt

Status: RESOLVED INVALID

(Thunderbird :: Mail Window Front End, defect)

Description

[John David Galt]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Thunderbird version 1.0 (20041206)

Whenever a mail folder's summary file has to be rebuilt (which happens quite
frequently and unexpectedly, often because Thunderbird has hung or Windows has
crashed), the Threaded setting (View menu -> Sort By -> Threaded) gets turned
off for that folder.

Reproducible: Always

Steps to Reproduce:



Expected Results:  
A folder's threadedness setting should never change unless requested by the user.

Possibly related to bug 251515.

The threadedness is *stored* in the .MSF file.  If that file is being rebuilt 
because it's been corrupted or deleted, how do you expect the program to know 
what the settings stored therein were?

Then that just means the setting needs to be moved to a more secure storage
location, or Thunderbird needs to close .msf files more often so that they won't
need to be rebuilt when not requested.  This is a real problem that needs to be
fixed, so it should not have been marked invalid.

we do actually try to restore the thread/sort when we delete a .msf file because
it's out of date. If it's corrupt, there's not much we can do, but I'm guessing
it's getting deleted because the mailbox timestamp is getting mucked with.
