115381 - switching folders doesn't load the folder

Status: VERIFIED WORKSFORME

(SeaMonkey :: MailNews: Message Display, defect, P2)

Description

[Suresh]

I've seen this for a while now. Sometimes if I switch between folders, the new
folder doesn't load. The cursor appears in hour-glass mode and no response from
the app.  I've seen this in newsgroup folders too.

Build: todays commercial bits on win2k

I'm seeing this increasingly often on win98 with newsgroups.  When this happens
it seems to toy with QuickSearch and mess that up tremendously. Once I exit and
return, all is well for awhile. Seems to happen more after I've been in mailnews
awhile.

I've seen this too.  If anyone can figure out how to reproduce this, it will
help a lot.

Comment 3

[Suresh]

I think I see this bug in this case: Switching folder from A to B, new mail
comes in folder A. 

Comment 4

[Suresh]

I saw this again today. Exact same thing happened as I mentioned above. 
Switching from folder A to B, and new mail arrives in A when I clicked on B.

[Christopher Aillon (sabbatical, not receiving bugmail)]

I'm seeing this quite frequently now and most often when first launching MailNews.

I start Navigator first usually.  When I'm ready to get inundated with bugmail,
I launch M/N.  My bugmail account displays as the second account, so my main
account is selected first.  Once bugmail starts pouring in, if I switch folders,
then the new mail count stops, and I get an hourglass although mails keep
downloading.

So I would list steps to reproduce as:

0a. Have a bugmail account or other mail account that gets spammed regularly and
let mail build up.
1.  Load MailNews and click on a folder that isn't your bugmail account.
2.  While mail is still downloading, switch to that folder.

And then the results are an hourglass after finishing downloading mail.

Changing OS to all since I see this on recent Linux trunk builds.

Is it a dup (or at least similar) of bug 115380?

Comment 8

[Cavin Song]

Here is how I tried to reproduce the problem:

1. Defined a filter rule to move new mail msgs to folder 'a'.
2. Used a Linux shell script to send a bunch of messages (100) to a test mail 
acct.
3. Set the check new mail interval to 1 minute so that I could figure out the 
time new mail check would knick off (for example, at every 25th second of a 
minute biff would go off).

The I filed the shell script to send 100 msgs 45 seconds before the biff went 
off and clicked on/opened folder 'a' (ie, stayed in folder 'a'). When it's close 
to the check mail time (because I knew when biff would go off) I opened folder 
'b'.

I tried this more than a dozen times and I still could not reproduce the 
problem. During these tries, I think I must have clicked on folder 'b' right at, 
a little bit before and a little bit after the time biff went off.  I also 
double checked the scenario with Suresh (who reported the problem) and he agreed 
that it's very close to the scenario when he experienced the problem.

Just an update on the investigation of the problem.  One more note, "the new 
folder doesn't load" means that the thread pane still shows the msg list from 
the old folder (ie, folder 'a') and it does not mean that the thread pane is 
empty.

Cavin, I've seen this scenario too where this happens: 
1. select any folder(A) and ctrl A to select all msgs. Shift + delete.
2. Try to load another folder. It doesn't load for me. 

I've seen this couple of times (I don't delete all the contents of folders much
;-) ).  If you couldn't duplicate this, try folder A sorted by Thread. 

PS: I'm not sure the above scenario is the same cause for the problem I
mentioned before.

Comment 14

[David :Bienvenu]

Can anyone say they saw this after 1/18, which is when I fixed bug 119404 ? thx.

Comment 15

[Suresh]

I'm pretty sure I saw this bug once like 2 weeks back.

Comment 16

[David :Bienvenu]

Laurel, are you still seeing this?

Comment 17

[laurel]

No, I haven't noticed this recently.

Comment 18

[David :Bienvenu]

Marking verified worksforme

Comment 20

[laurel]

I hate to say this, but I'm seeing this again in today's trunk build on win98.
I'm sure I can't reproduce it at will, so I hesitate to reopen it, but thought
I'd at least comment.  I've seen it a few times today.
