[Mailsync-list] Preserving order of synced messages

[Bernie M. <lis...@bl...>]

Hi there!

I'll admit I'm using an old version of mailsync (4.4.4, since that is
the latest one ported as a FreeBSD port [sigh]).  But I've had a quick
glance at the current code in CVS, and so I am guessing that STL sets
are still pretty fundamental to the implementation of mailsync.

Unfortunately, this means it's pretty likely that that mailsync still
exhibits a problem that I've observed in 4.4.4, and that is it cannot
preserve the order of messages in synchronised folders (unless I am
missing something).  Is that the case?  If so, how difficult would it
be to keep the sorted list, iterate through that while testing against
the appropriate set to decide whether a particular message should be
copied?  (That is, replace the MsgIdSet::iterator loop with something
that preserves order.)

As it stands, it's a bit irritating to synchronise high-traffic folders,
because the destination gets jumbled.

On an unrelated note, I notice also that any keywords I assign are lost
in the copy.  (The X-Keywords line is replaced by X-Original-X-Keywords.)
However, I saw nothing in the mailsync sources to indicate that it was
munging them, so perhaps that is a c-client problem?

So I'm still searching for an ideal mail synchroniser.  (Ideal for me,
that is.  Otherwise I've been pretty impressed with mailsync so far.)

Cheers,

    Bernie
