Andrzej Rusin commented on IMAP-370:
------------------------------------
Eric,
Thanks for comments.
Lock: the difference is that COPY does not alter the source folder content,
while MOVE does. That's my concern. But maybe there is some way to safely lock
both folders?
OTOH, for the implementations that MOVE makes any sense, it will be very quick
and atomic (that's the whole point of MOVE). So - not having lock is less
unsafe than it seems.
For implementations that can't do MOVE quickly it does not make much sense.
I probably do not know maildir and jpa MMs to implement MOVE correctly. Someone
needs to help.
Let's discuss the legacy MOVE after we have the basic MOVE in place.
What would be the next steps?
Thanks,
Andrzej

> As we see at
> http://datatracker.ietf.org/doc/draft-ietf-imapmove-command/ballot/ IETF is
> about to finally accept the IMAP MOVE extension.
> This extension enables great performance optimization possibilities for the
> more advanced Mailstore backends, eg the ones that use a underlying
> relational or non-relational database:
> One of the most common usage scenarios in IMAP is moving messages across
> folders, and with the MOVE extention it can be finally accomplished without a
> COPY/DELETE cycle on certain Mailbox backends.
> Therefore, in my belief, it would be very nice to have that extension
> implemented in James.
> Some of the bundled Mailstore implementations already are based on SQL/noSQL
> datasources, and can directly benefit from it.
> Some of the independent Mailstore implementations (including mine) can
> benefit from it too.
> Some of IMAP clients (including Thunderbird as of 3.something) already
> support that extension or the X-MOVE or X-AOL-MOVE one.
> So James has a great opportunity to be the leader of standards adoption on
> the server side.
> What do you think? Please comment.
