[jira] Created: (DIRSERVER-1081) Injecting more information in the opContext structure

Injecting more information in the opContext structure
-----------------------------------------------------

                 Key: DIRSERVER-1081
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1081
             Project: Directory ApacheDS
          Issue Type: Improvement
    Affects Versions: 1.5.1
            Reporter: Emmanuel Lecharny
             Fix For: 2.0.0


As each server operations now use this opContext for every operations, it would be useful to inject more information into this context, like access to the registries, or other things which are currently stored locally in each interceptors during the initialization phaze.

It will be more elegant, will allow global modification of the server without having to reinit all the interceptors, and could help to define specific operation's context for a request (for instance, if we think about an operation associated to a specific partition, we could perfectly inject the partition associated registries, allowing us to have per-partition regristries, instead of one single registries set for all the partition - just an idea)

I don't know if this is a good idea since the registries are services - I'd
leave it up to dependency injection
to handle populating dependent services like the interceptors.  You're also
presuming that these registries
will be used only in the code (methods) dealing with request processing.
There are other places where they
are used.

Also you cannot split up the registries just for a specific partition.
Maybe I did not understand properly because
does not make sense.  Can you clarify?

What registries are you referring to? Schema registries?

Re: [jira] Created: (DIRSERVER-1081) Injecting more information in the opContext structure

Hi David,

I'm not thinking about interceptor specific data, but generic
informations. To me, we have a lot of structure which are associated
during the interceptor initialization which are not associated with
the interceptor itself, but as the operation needs them, we have added
them in the init phase. Not sure this was the best idea, because that
means you have to create a lot of static variables all over the
interceptors.

I'm not sure that the cost of passing a new element in the opContext
will be measurable...

Anyways, we have to discuss further what I have in mind, because it's
a little bit fuzzy for me too atm ;)

I tend to think this is not a very good idea or else I don't  
understand it.  I think the interceptors will be clearest if they are  
injected (by spring or external setup code) with whatever information  
they need to do their job that is not request specific and the  
opContext objects are setup with only the request-specific  
information.  Likewise the opContext object will be quickest to setup  
the less information they have in them.

thanks
