using the config subystem.
patch 5 changes:
md-sal/pom.xml correction
patch 4 changes:
Moved data tree api and impl to yang-tools based on earlier comment
Patch 3 changes:
1. Included sal-inmemory-datastore dependency in TestHelper.java for PaxExam
integration test cases [Weird that it was working earlier and my local controller full build were passing]
Patch 2 changes:
1. Keeping schema service as part of opendaylight-dom-broker-impl for backward comptability scenario
2. Initializing InMemoryDOMDataStore by default if config-dom-datastore and
operation-dom-datastore are not found
3. Updated 01-md-sal.xml based on 1.
4. Regarding the comment of moving data tree in yangtools. It shall be done in
separate patch.
This is done to replace InMemoryDOMDatastore with distributed-datastore
The changes done are:
1. Created a new sal-inmemory-datastore bundle and moved the
store/impl source files from sal-dom-broker and the corresponding
InMemoryDOMDatastore test cases.
2. Created two yang config models in sal-dom-spi that represent
the configurable config-dom-datastore and operational-dom-datastore, that
are of service type DOMStore
3. In opendaylight-dom-broker-impl.yang of sal-dom-broker, in the augment of dom-inmemory-data-broker added two container config-data-store and operational-data-store that refer the service implementations of service defined in sal-dom-spi
4.In sal-inmemory-datastore bundle, created a yang model opendaylight-inmemory-datastore that provide the implementation of the sal-dom-spi service definitions mentioned in 2 -- The implementaions are augmented to have schema-service container required by InMemoryDOMDatastore for registering itself for scheam changes
5. Updated the 01-md-sal.xml with the above changes
6. Update the distribution pom.xml to include sal-inmemory-datastore.
