Thomas Mueller reassigned OAK-567:
----------------------------------
Assignee: (was: Thomas Mueller)
Performance is much better now, but I guess it's still slow for large diffs.
> DiffBuilder performance problem
> -------------------------------
>
> Key: OAK-567
> URL: https://issues.apache.org/jira/browse/OAK-567
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: mk
> Reporter: Thomas Mueller
>
> The org.apache.jackrabbit.mk.model.tree.DiffBuilder is very slow because it
> uses:
> {code}
> HashMap<NodeState, String>
> {code}
> and at the same time
> {code}
> class AbstractNodeState implements NodeState {
> /**
> * Returns a hash code that's compatible with how the
> * {@link #equals(Object)} method is implemented. The current
> * implementation simply returns zero for everything since
> * {@link NodeState} instances are not intended for use as hash keys.
> *
> * @return hash code
> */
> @Override
> public int hashCode() {
> return 0;
> }
> }
> {code}
