383777 - Cannot copy messages from IMAP folder to POP3 folder

Status: RESOLVED FIXED

I have two email accounts, an IMAP account from my employer for business
use, and a POP3 account for all other use (including Mozilla use).
Someone sent a message about Mozilla stuff to my IMAP account, and it 
started a thread that grew large.  That thread is now in one of my IMAP 
account folders.  Some of the people who wrote in that thread caught the 
error and sent their replies to my POP3 account, so I have (er, had) 
messages from this thread in folders for both accounts.

Now, I want to COPY that thread from my IMAP account folder to the folder 
in my POP3 account.  So, I went into the IMAP folder, typed the subject 
of the thread into the search bar, highlighted all the messages in the 
message list pane, right clicked, and chose "Copy to" ... the POP3 folder.

No copy happened.  But worse, it DELETED the emails with that subject from
the POP3 folder!  Data Loss!

I have tried this several times now.  I tried making the IMAP folder be 
"available for offline use", which copied the folder contents to my local
hard drive, but even after that I cannot copy the messages into the POP3
folder.  

I created a folder under "local accounts", and tried copying the messages
from the IMAP account to that local account folder.  No copy occurred there
either.  

After one of the failed trials, I went to look at the contents of the POP3
folder, and it appeared completely empty.  I tried to search it, and got a
pop-up dialog telling me that the POP3 folder was "busy".  Eventually I 
exited the program, restarted it, and rebuilt the MSF.  I hoped that would
get my deleted mails back, but no joy.

I retract the dataloss claim.  The messages were found in another folder.
But the inability to copy IMAP messages into POP3 or local-account folders
remains.

Is 1.5a basically the trunk? I'm seeing something similar - copying multiple imap messages at a time to local folders doesn't seem to work.

Comment 3

[Nelson Bolyard (seldom reads bugmail)]

Yes, 1.5a is the trunk (as noted in the bug "version" field).  
In the last 7-10 days they've changed the version number shown in the trunk
builds from 1.5a to 2.0a1, so you'll start to see that number soon.  But 1.5a
and 2.0a1 are essentially the same thing for mail/news purposes: the trunk.

yeah, that's what confused me because I was seeing that 2.0a1 number flying around. I'll debug this now.

Sounds same phenomenon as Bug 382836.

Comment 6

[David :Bienvenu]

maybe, if multiple messages are involved - a single message copy works fine.

Comment 7

[David :Bienvenu]

I believe the problem is that we (i.e., most likely I) broke the imap url parser, such that we fail to parse the url that we're generating to do a multiple message copy. Or else I broke the generation of that url...

FYI.
According to Bug 382836 Comment#3 and Bug 382836 Comment #10, it was between 5/21 and 5/22.
