46501 - Unnecessary SELECT when IMAP copy across imap servers

Status: VERIFIED FIXED

(MailNews Core :: Networking: IMAP, defect, P3)

Description

[Henrik Gemal]

According to:
news://news.mozilla.org/3876AA19.AD400A26%40netscape.com
there is an unnecessary use of SELECT when you do a copy (APPEND) to a IMAP 
folder.
 
To quote <[e-mail]>:
"Additionally, I noticed that Messenger does a SELECT and caption download on 
the destination folder before starting to APPEND the messages.  This is 
completely unnecessary."

Jeff implemented copy. load balancing to him. An extra select would be very bad.....

John posted that message way back in January. My guess is that this was fixed a
long time ago. Henrik, have you observed this in a build from the past few
months, or were you just following up on John's posting?

[Henrik Gemal]

Yeah, I was just following up on John's posting.
This is what's happening:
You have imapserver1 and imapserver2 and would like to copy msg1 from inbox on 
imapserver1 to imapserver2.
First you select the inbox on imapserver2, then you select the inbox on 
imapserver1. Then you select msg1 on imapserver1 and select Copy to 
imapserver2/inbox.
And APPEND imap command is executed and no SELECT is execute. Fine.

But if you dont select the inbox on imapserver2 first a lot more IMAP command 
are executed when you select Copy to imapserver2/inbox, including SELECT command 
etc...

So, this only happens when you copy across imap servers, and perhaps when you
copy from a local folder to an imap folder. Not quite as exciting as if it
happened on all IMAP copies.

Based on the following IMAP log, there is no SELECT and caption download on 
the destination folder before starting to APPEND the messages. 
Marking as verified!!
