} Does this mean that Berkeley DB should not be used at present?
I use Berkeley DB extensively in native mode (compile using USE_DB) and
have had no problems - this is with db version 1.85. I have heard that a
couple of people have had problems but have no details as to whether they
are using it in native or emulation mode, versions etc.
db v2.x is a quite different beast, but *should* compile and work OK with
exim (maybe with a slight change for include files or libraries). It is
likely to be *less* efficient when used as a drop in replacement for
db/dbm/ndbm, basically because it makes a different set of assumptions.
This means that an open/close operation is expensive (or more so than
previously), but the other operations should be be faster. The problem is
that exim uses a hit and run approach to db files - the operations done
each time are
open
lock
dbopen
read/write (normally a single operation)
dbclose/flush
close (effective unlock)
I'd not suggest using exim with db v2.x unless you know what you are
doing, or until someone works out the best way of doing this.
