jeff - in the release Win32 build from today (2000-01-19-13-m13), I created a
new POP account and was able to delete messages and have them move to the trash
folder.

Hmm.. I pulled my tree this morning. I'll try it again to make sure.

Comment 3

Another good one.

Comment 4

[jefft]

Reassign to myself for further investigation.

Looks like the problem is manifest from a corrupted database. If I removed the
*.msf everything works fine. The question would be how can a database get
corrupted and is there anyway we could detect it and then correct it.

FWIW, I've never seen a corruption in msf files. What I have seen is headers put
into msf files with the wrong message keys, status offsets, etc. This gets fixed
when we reparse the folder, which happens when you delete the .msf file.

M14 ... more likely

Linux (2000-01-20-08 M13)
FYI:
I try it in today's linux build again.  The problem still exists.
After a crash, I relaunch Messenger and try to delete a message in the POP
account, Delete does not work. But if I remove  the .msf files, it works.
However, I have not seen this problem in the IMAP account.

I don't think this should be PDT+ anymore.

Comment 10

[jefft]

Okay, I am clearing the [PDT+] flag.

Comment 11

[lchiang]

removing dogfood entry.  There is a workaround for this.  

Comment 12

[David :Bienvenu]

David, could you try to reproduce this problem and figure out what's going on?

Comment 13

[davidmc]

It's hard to figure out why something does not happen, because the reasoning is 
similar to proving a negative.  I might need to study all the code which intends 
to delete something, before I see why nothing happens.  I can look into it.

Comment 14

[David :Bienvenu]

The first thing to try is to recreate the bug. Especially, play with things like 
deleting a local message, then Undoing it, then deleting an other mesage, redo, 
etc.

Comment 15

[davidmc]

Sure thing. (I was trying to recreate the other bug for specifying a port for a 
pop or smtp host, but I'm having trouble getting symbols where I crash even when 
I load all the symbol files I can find.)

Comment 16

[David :Bienvenu]

these are mine now, I guess.

Comment 17

[selmer (gone)]

Can we make it so we detect the crash and rebuild the .msf file in that case?
It seems like there's a high correlation between the crash and the symptom.  Any
shutdown that's not "clean" might be the condition here.

(I know this has the effect of only hiding the symptom, but if it's caused by
crashing I think that's probably as good as it gets for now.)

Comment 18

[David :Bienvenu]

we probably do recreate the .msf file, Steve. But there's probably a problem 
with the TRASH flag setting on the .msf file.

Comment 19

[selmer (gone)]

Not beta2 stopper, marking M17.

Comment 20

[jefft]

I am sure this is fixed by now.

Using build 2000-05-16-09 on win98, mac and linux this is fixed.  I deleted a 
few msgs in my POP acccount, the crashed the product with a known crasher 
(expanding a newsgroup). Reopened Mail, selected my POP account and deleted 
messages.  If anyone is running into this again, please comment and give 
a scenario, then reopen.  Verified
