[dna-issues] [JBoss JIRA] Commented: (DNA-548) The Session That Graph Changes Originate From Should Be Available To The NetChangeObserver

    [ https://jira.jboss.org/jira/browse/DNA-548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12496887#action_12496887 ] 

Randall Hauch commented on DNA-548:
-----------------------------------

The ExecutionContext serves as the universal mechanism by which the DNA code knows the context in which operations are performed, and is available to the connectors that process the requests, the session that creates the requests, and the Observation system that post-processes the (complete) requests.  The JcrRepository.login(...) method always creates a new ExecutionContext via the ExecutionContext.with(...), which means that every JcrSession implementation has a unique ExecutionContext.  Therefore, if we add a unique identifier to the ExecutionContext, that identifier would correspond to the Session instance.

> There is no way for the ObservationManager to obtain the session from the NetChanges/Changes/ChangeRequest objects. The session identifier is needed to implement the event notification of the ObservationManager. Specifically, listeners are registered with a "noLocal" flag indicating if they want or don't want to receive events from the session that they are registered in.
