137303 - New message count is lost during folder compact

Status: VERIFIED DUPLICATE of bug 100781

(MailNews Core :: Networking: IMAP, defect)

Description

[Bill Sheppard]

Using Mozilla release 0.99 (2002031104)

Upon allowing Mozilla to compact folders, all new messages in my Inbox were
marked as read.  This could be seen occuring as the folder was being compacted,
the new message count in the left hand pane would count down.  Upon completion
of compaction all messages in the inbox were marked as "read".

This may be related to bug 124513 (Data Loss after Mail folder compaction), that
reports the same problem seen in a local mail folder.

How reproducible is this? Have you tried a newer build?
And what does "allowing Mozilla to compact folders" mean? Don't you have to
manually start "compacting" (purging of messages marked as deleted) on IMAP with
the "marked as deleted" model?

I've seen this happen on major builds since at least 0.96, haven't tried any
nightlies.  By "allow compaction" I'm referring to the dialog box "Do you wish
to compact all offline and local folders to save disk space?", which I presume
is related to Preferences/Offline & Disk Space/ "Compact folder when it will
save over x KB".  I have my Inbox set to download messages.  In the past when I
have seen the new message count dropping during compaction I've manually
interrupted Mozilla (by killing the process) and things were fine upon
restarting, but this is presumably because the compaction is taking place on a
copy of the mail folder, and when I restarted Mozilla was using the original
mail folder.

I agree, this appears to be the same as <a href="show_bug.cgi?id=124513"
title="NEW - Data Loss after Mail folder compaction">bug 124513</a>, although
that entry doesn't appear properly categorized.

This is a dupe of bug 100781 "Unread messages changed to read when compacting
folder", and was just (04/15/2002, 15:41) fixed on the trunk by bienvenu.

Verified as dup.
