----------------------------------
Summary: Race condition in the CompositeNodeStore#merge
Key: OAK-6376
URL: https://issues.apache.org/jira/browse/OAK-6376
Project: Jackrabbit Oak
Issue Type: Bug
Components: composite
Reporter: Tomek Rękawek
Fix For: 1.8
Following line in the CompositeNodeStore#merge() is prone for race condition:
{code}
NodeState processed = commitHook.processCommit(getRoot(), rebase(nodeBuilder),
info);
{code}
We should compare the rebase() results with the getRoot() method, but with the
nodeBuilder.getBaseState(). Otherwise, any changes in the root between
getRoot() and rebase() invocations will lead to processing external changes in
the commit hook.
