pulsar: 3 CWE-407 defects — load-manager/replicator/namespace List.contains O(N^2)
...
pulsar-0001: ModularLoadManagerImpl.reapDeadBrokerPreallocations() receives
aliveBrokers as List<String> from listLocks(); .contains() inside O(B) loop
→ O(B^2); fix: HashSet wrap before loop.
pulsar-0002: PersistentTopic.removeOrphanReplicationCursors() and
checkReplicationStatus() call configuredClusters.contains() (List<String>)
inside loops over cursors and replicators → O(C×R); fix: HashSet wrap.
pulsar-0003: NamespacesBase.internalGetTopicHashPositionsAsync() calls
allTopicsInThisBundle.contains() (List<String>) inside for loop over query
topics → O(T×B); fix: HashSet wrap before loop.
