I will investigate for all the different combinations between NNTP, IMAP and local. It looks like only NNTP to local is working right now. Also we are still doing move across server when we should be doing a copy.

moving to mozilla 0.9.2.

The first part of the fix are the js changes that do a copy when the servers are different. The next is when we copy multiple imap messages to local we were not adding the msgKey in EndMessage() that gets called after each message. Also prevent adding the key in another place if multiple messages are being copied from imap to local. When we do local/nntp to imap we need to add the msgIds to the imapundo object, also when we issue a search for finding the uid we need to be in the selected state. cc david for review.

everything looks ok, but instead of adding something specific like "GetSrcIsImap()", would it be better to add "GetSrcFolder(nsIMsgFolder **folder)" and have the caller QI to see what the folder type is? What if later a caller wants to tell if the src folder is news, or another type?

[minor nit] it should be GetSrcIsIMAP(), not GetSrcIsImap() sr=sspitzer concerning my earlier comments (about making the solution generic): naving is just adding a getter to get at a member variable on the undo transaction, (m_srcIsImap4), so I can't object to that. in an ideal world, nsLocalUndoTxn.cpp would be written in a generic way, not depending on IMAP. but that's not going to happen any time soon [and we've got bigger fish to fry], so there is no reason to make naving go out of his way to make his patch general when the underlying code isn't. that would just be re-arranging the chairs on the titanic

adding PDT+. Please check into the trunk as soon as possible.

fix checked in.

I moved and copied about 5 messages which were both plain text and html message. The following scenariors were tested with move-undo move, copy-undo copy. imap-local folders, local-imap, news-imap(copy only), news-local(copy only),imap-pop,pop-imap, local-local, imap-imap, pop-pop. I used inbox, drafts, userdefined folders for moving, copying message with the above scenarios. If you find any other specific scenario which has problems with move, copy or undo please log a seperate bug for each different issue and do not reopen this bug. builds used in verifying the above: 2001061807win98, 2001061808 linux, 2001061808 mac.
