Also as classic starts using shared memory to hold common data structures.

Yes, I agree it's not a killing but a merging, of superserver and
classic server architecture taking (hopefully) the best of both, and
abstracting out some of the runtime differences (threads/processes
allocation to shared memory/normal memory for instance). I see this as
very beneficial.

However, in addition to "super server" and "classic server" we also have
the original classic direct connect model (or "embedded" mode as I've
termed it).

I know that many think that we only need a firebird server version, but
in building embedded solutions the direct connect model has some

I would hope, and think it's reasonable, that a smart way can be found
in the merge of the two server architectures to preserve the original
embedded architecture as an option.

Quite likely, since locking, interprocess communication, and security
operation differs so much in embedded mode to (both) the server modes,
that to aid the merge of the servers, the embedded mode may need to
loose it's multiclient ability, thus restricting db access with embedded
to one client at a time. That is still likely to be suitable for a
desktop app or a palm pilot program storing a bit of data.

Jim I think your lucky, (and we're also lucky) that you have some time,
especially paid time, but keep it in mind, as you find crap etc in your
travels, that having time, or paid time, is not a luxury many here have.

We're all after the best code/system, and I personally prefer you care
enough about the code, do the "Grrr" thing even when it's occcasionally

(I know for my part, the unix/linux makefiles although better than the
original, are certainly not what I'd like them to be, I'll wait my turn
for you to drift into them and for me to be found out :-).
