Hi,
Firebird is the open source development effort based on the interbase
source code released by Borland about a year ago. Borland eventually
released source to everything except the licensing stuff and the load
testing suite. Since Borland seemed unwilling to allow any outside input
into their source tree, the firebird project was formed to pursue community
development. The firebird community enjoys the advice and participation of
the original developers of Interbase, Jim Starkey and Ann Harrison. My
impression is that development on firebird is proceeding at many times the
rate of interbase@ borland. For instance, firebird developers
--found and fixed the security backdoor
--ported firebird to (at least) Darwin, BSD, and HP (There is a Solaris
version, I don't know if Borland has one too)
--fixed many bugs
--added some support for more modern file system sizes
--made significant progress on developing a usable build system
--made significant progress on translating the code base to c++
Interbase has had 2pc since the mid 80s, there are some differences with
what XA expects, but I believe these can be worked around to result in a
real XA-supporting jca-jdbc driver.
