Eric Charles commented on IMAP-370:
-----------------------------------
Hi Andrzej,
I finally had to remove the MoveProcessor from the chain as it was breaking the
connection when a copy command was issued by the client.
This is due to the AbstractChainedProcessor.isAcceptable method which relies on
Class.isInstance to see if the processor is valid for the command.
In this particular case, as Move extends Copy, the condition is fullfilled and
the move is assigned to the copy.
The ideal would be to use composition instead of extension.
I am happy to discuss any valid proposal (change the isAcceptable logic...)
although I would prefer the composition approach keeping the isAcceptable as it
is now.
Thx, Eric

> 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.
