[Vm-dev] Re: updating and compiling the BerkeleyDB plugin

[Paul DeBruicker]

Hi David,

It is the same.  I did ask Stephen Pair and he said it would be fine to port
it to LMDB , also to make the resulting port MIT.  LMDB is the database that
backs the OpenLDAP project (https://en.wikipedia.org/wiki/OpenLDAP), and is
under the OpenLDAP license:
(https://gitorious.org/mdb/mdb/source/3368d1f5e243225cba4d730fba19ff600798ebe3:libraries/liblmdb/LICENSE) 
which is considerably more permissive than what Oracle is offering with
BerkeleyDB.  

My thought was to make it compile & work with BerkeleyDB as an intermediate
step in an effort to limit the moving parts I was learning about.  Then
after that port it to LMDB



Thanks for looking into it.


Paul
