227476 - Mozilla crashes when returning from off-line

Status: RESOLVED WORKSFORME

(SeaMonkey :: MailNews: Backend, defect)

Description

[francois-xavier kowalski]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5) Gecko/20031007

IMAP folders.  Going off-line works fine.  Messages sent off-line are actually
stored in the "Unsent Messages" folder.  When returning on-line, Mozilla mail
reolves the SMTP server, successfully sends messages & then crashes.

This behaviour can be reproduced at 100%.  It also happens on Linux (RedHat
Linux 9) on i386.

Reproducible: Always

Steps to Reproduce:
1. Go off-line (Download messages)
2. Write messages & "Send Later"
3. Go on-line

Actual Results:  
Mozilla crashes.  Restarting it, none of my folders is corrupted, neither any
local copy.  This is not a complete show-stopper -- my data is not lost -- but
time comsuming (Mozilla startup on Windows is __SLOW__ ).

Expected Results:  
Go on-line normally, like after a cold startup.

At the time of Mozilla 2.1 (or before, I do not remember), I added the
configuration item below, because I was using procmail for mail pre-filtering on
various local folders on the server.

check_all_imap_folders_for_new = true

The procmail capability has now been removed, so I have set this value yo:

check_all_imap_folders_for_new = false

Seems that mail.check_all_imap_folders_for_new has now disappeared from
about:config.  Is mail.check_new_mail an equivalent feature?

can you try a 1.6b build just to make sure the bug is still there?

Comment 3

[francois-xavier kowalski]

I found no 1.6b on the FTP site <http://ftp.mozilla.org>, so I will try with
1.6a.  Any issue with this?

Comment 4

[David :Bienvenu]

1.6a would be OK, but a recent nightly build would be better, which is in effect
a 1.6b build -

test on 1.6b show a pretty different behaviour:

1) Mozilla no longer crashes when returning on-line

2) Accepting to compact local & off-line folders when off-line leads to
corrupted .msf files.  They must be destroyed. That bug was fixed by 1.5.  It
seems to be back in 1.6b

3) After having gone off-line, messages of folders marked "available for
off-line" are not readable (need to go on-line).  However _while staying
offline_ Doing "Properties > Offline > Download Now" makes them visible.  Funny
bug... ;-)

In brief: 1.6b fixes the current problem, but seems to bring a regression wrt/
1.5.  The re-appearing bug being the cause of my migration from 1.4 to 1.5...

Comment 6

[francois-xavier kowalski]

I have stepped back to 1.5, because of the show-stopper described earlier in
this bug-report. I had to manually re-set every off-line properties of every
IMAP folders: even when set, no message was downloaded.

As a result, Mozilla-1.5 no longer crashes when going back on-line.

I see 2 possibilities:

1) The old mail.check_all_imap_for_new was wrecking havoc in the Mozilla
configuration.

2) The bug occurs when going-back on-line when another Mozilla is running using
the same IMAP folders (I have a desktop & a laptop, both connected to the same
mail account)
