Michael Dürig created OAK-5355:
----------------------------------
Summary: Too eager refreshing of tree permissions in
SecureNodeBuilder
Key: OAK-5355
URL: https://issues.apache.org/jira/browse/OAK-5355
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Michael Dürig
Fix For: 1.8
{{SecureNodeBuilder.baseChanged()}} calls
{{SecureNodeBuilder.getTreePermission()}} even though the tree permission would
be calculated lazily as needed anyway. Re-calculating the tree permissions at
this point bears the risk of accessing stale data from the underlying not yet
fully refreshed root (when being called e.g. from {{MutableRoot.refresh()}}.
I would thus argue for removing the call to
{{SecureNodeBuilder.getTreePermission()}} from
{{SecureNodeBuilder.baseChanged()}}.
See also OAK-5296 for an in-depth analysis.
