BuildID:    2001050304 on WinNT 4.0

While online, if you select a message(s) to be downloaded (by
using Get Selected Messages or Get Flagged Messages method as
with this current build (2001050304) the Sync Dialog window
is not currently implemented) and then go offline. Move the
message(s) you have downloaded to another folder. Go to that
folder and try to read it and you will not be able to see the
text body as it is blank.

Reproducible: Always
Steps to Reproduce:
1.Start Messenger
2.Log into your IMAP mail account (i am using move to trash can deletion model)
3. While online, select some messages (From your inbox) to be downloaded (must 
at least select 2 messages) by either method:
  a) - select some messages
     - Go to the menu and choose File->Offline->Get Selected messages
  b) - flag some messages
     - Go to the menu and choose File->Offline->Get Flagged messages
4. Go offline
5. Click on the downloaded messages (should be in italic)
6. You should be able to read them
7. Move those messages to another folder(s)
8. Go to the folder where you moved the message to
9. Click on that message that you just moved from your inbox

Actual Results:  You are not able to read it. If you go back online you are
still not able to read it. The text body is blank whether you are in online or 
offline mode.

Expected Results:  You should be able to read it while in online or offline 
mode. You should be able to see the text body.

Noticed some new additonal results? When I go back online, I
also noticed that sometimes the message that was downloaded 
and moved to from inbox to another folder now
looses it's 'italic mode'. And it behaves like a non-downloaded
message. If i go back offline, I can no longer read the message
and I get the "The body of this message has not been downloaded from the server 
for reading offline..." message. 

See bug 78520
where I first mentioned the original problem in general terms.

I tried this out.  Here's what I found.  Moving a download message while offline
doesn't copy the body.  If you go online the message disappears from the folder
but the next time you load the folder the message reappears and you can see the

David is going to look into making the message not disappear when going online,
which will make this bug less severe.
It turns out that 4.x had the same bug that Scott reported which is the following:
If you do an offline playback synchronization and the folder that is selected
has messages that were moved into it offline, the moved messages disappear until
the next time you select the folder, or do another playback synchronization, or
select the source folder of the move.
Wanted to add quick note. In testing bug 83734, I noticed
messages also disappearing when you try copying:
-go offline
-copy a message to another folder
-click on that folder where you copied the message to
-you can see the message
-go online
-message disappears from folder

You have to click on another folder and then go
back to 'see' the message that you copied.
OK, Gary and Scott, the move/copy messages disappearing behaviour you're seeing
is a different bug and should be separated from this one. The disappearing
messages is a 4.x bug as well which means I successfully ported the bug :-) . I
think we probably want to fix both bugs but I'll leave that up to Scott to
decide. Fixing this bug won't fix the disappearing messages bug at all - they're
separate. Gary, can you file a new bug on the messages disappearing bug when you
select the dest folder of the move/copy? Thanks!

I have a fix at home to copy the offline message bodies when you move/copy a
message while offline - I'll attach it tonight.
Whiteboard: [nsbeta1+] → [nsbeta1+] Fix in hand
Attached patch imap part of fixSplinter Review
cc'ing Seth and Navin for review. The one thing that's missing from this fix is
that when you go back online, we forget the downloaded message in the dest
folder but at least you can still read the message while offline.
I have already reviewed base part of the fix. r=naving on imap part of the
fix checked into trunk.

2001-07-05-08-trunk/ mac os 9.0.4

Verified On trunk only:
That moving or copying a downloaded message (while offline)
from its original folder to a new folder results in being able
to read the message in the new folder while you are offline.

Tried drag and drop method (Drag&Drop doesn't work in linux see bug 89438), 
Message|Move Mesage, Message|Copy message,
and using move to/copy to when right clicking a message and
they all work. You are able to read the message if it's moved/copied
to another folder while offline.

Note: when going online the message may 'dissapear' but will reappear
if you visit the folder again (see bug 84249) and once you go
back online, the message you moved while in offline mode will loose it's
downloaded status once moved (think i have to file a new bug
on that one). So if you go back offline and try to reread the
message you moved/copied earlier, you won't be able to.

leaving status as is.

oopps Removing Keyword Vtrunk since Verified on the trunk
Keywords: vtrunk
yes, I knew (and said) that would happen (losing the offline message body when
you went back online). It's very hard to fix that, and my guess would be that it
didn't work in 4.x either.

Ok David, I won't file bug on a message loosing its downloaded
status if you move it to another folder while offline.

since there was a new bug filed on the disappearing message bodies, what is left
to fix in this bug? 
Good question Scott. I think it is 'resolved;.

David want me to change status to resolved?
And next week I'll reverify on trunk.
what's left, is perhaps trying to fix it so that you don't lose the bodies when
you go back online.
It looks like 84249 was filed for that.
84249 is about the msg hdr disappearing. I was talking about the offline message
body disappearing when you go back online.
ok, adding nsenterprise+
changing summary to reflect remaining bug, which is that when you move a message
offline that has an offline body, we lose the destination msg offline body when
you go back online. 4.x had this bug too, and there's no perfect way to fix this
. The problem is that when we do the offline move, we create a dummy header and
associate the offline body with it. When you go online and download the real
header, we don't know that the real header corresponds to the dummy header. The
only way I can think of to know this is to compare the message-id and a few
other fields of the dummy header with the newly download header. I would
recommend not fixing this for the next release - no one's ever complained about
the 4.x behaviour.
Summary: Offline:Moving a downloaded message, while offline, from inbox to another folder results in not being able to read the message → Offline:Offline copy of an imap message moved offline is lost when going back online
sounds reasonable to me, especially if there were no complaints
in 4.x about this..
same here, I'm going to move this down to nsenterprise status for re-triage.
Definetly sounds like a good nsEnterprise- candidate.
