Summary: Avoid acquiring a kbase readlock when performing a working memory action
Key: DROOLS-1110
URL: https://issues.jboss.org/browse/DROOLS-1110
Project: Drools
Issue Type: Enhancement
Reporter: Mario Fusco
Assignee: Mario Fusco
At the moment all working memory actions (insert/update/delete) need to acquire a read lock on the kbase. This is avoidable making the kbase to deactivate (through their state machine) all the ksessions created from it before modifying the kbase itself.

[JBoss JIRA] (DROOLS-711) Kie Server unable to build KieBase which builds fine with kie-maven-plugin and unit test
by Kaan Bingol (JIRA)
[ https://issues.jboss.org/browse/DROOLS-711?page=com.atlassian.jira.plugin... ]
Kaan Bingol commented on DROOLS-711:
------------------------------------
I think the issue still persists in 6.3.0.Final. I have tested in a similar setup to the reported one. Client driver project only depends on kie-ci 6.3.0.Final and when the kie container is tried to be constructed, kie module unable to build due to the same reasons. However, if I remove "declare" statement from the rule file, it works or if I add the dependency of rules project (the one that build and uploaded into maven repository) into the main container project pom while still constructing the kie container from maven repo the issue is also gone. However, both are not a feasible solutions since declare statement is used for CEP and adding dependency contradicts whole building kie container from maven repository concept.
