One thing I forgot to say : the current configReader is not able to

in order to support all those 'dynamic extension' things talked about
in this thread
we have to depend extensively on reflection,
e.x instead of having a separate OC for each index implementation type
we need to
have a single OC like 'ads-index' with a MUST AT 'ads-indexClass' so
that we can
instantiate the class using default constructor and then inject all
the configured attribute
values into that object.
Yes exactly! This has to be done for all extension points in the server.
What are those extension points?
- Partitions and their associated classes.
- Interceptors and their associated classes.
- Authenticators and their associated classes.
- LDAP Protocol Handlers and their associated classes.
I guess there might be more extension points but this is what I see off
the
top of my head. And these things need to be using reflection with the same
MUST AT to class load the respective implementation that users might
provide.
There are more extensions point : ExtendedOperations, Schema
normalizers/SyntaxCheckers/Compartors.
ExtendedOperations are part of the LDAP Protocol Handlers.
And we don't need an extension point for Schema since the Schema Subsystem
already has this capability built in with updates via the protocol to extend
Schema. The schema extensions are directly loaded into the DIT and a
reflection mechanism is already in place to load them appropriately.
Tight.
Anyway, we have to focus on Partitions/Store/Index atm, this is the key
element at stake atm.
Note : this is *not* urgent. I opened the discussion, but I'm not sure
we want to do that before 2.0-RC1 is out.
