Commit 6c3c2c173bbcdf32a91d604857cae3d5f9b348b6 in nifi's branch
refs/heads/main from Tamas Palfy
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=6c3c2c1 ]
NIFI-7736 Fix: Empty All Queues performance - When authorizing request,
checking read/write credentials on encapsulated process groups and connections
was doubly recursive (for each element it added all child elements multiple
times again, making this exponential instead of linear).
> Duplicated permission checks in Empty All Queues

> Key: NIFI-7736
> URL: https://issues.apache.org/jira/browse/NIFI-7736
> Project: Apache NiFi
> Issue Type: Bug
> Reporter: Peter Turcsanyi
> Assignee: Tamas Palfy
> Priority: Major
> Fix For: 1.12.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> {{ProcessGroupResource.authorizeHandleDropAllFlowFilesRequest()}} checks the
> permissions for the Empty All Queues feature.
> It is traversing over the process group hierarchy to check all the
> connections in the sub process groups.
> Traversing seems to be not needed because {{getEncapsulatedConnections()}}
> returns all the connections in the hierarchy so the permissions can be
> checked the parent group level. Traversing + {{getEncapsulatedConnections()}}
> leads to duplicated permission checks for connections in the children process
> groups.
