------------------------------------
Summary: Wasted work in ClusterViewServiceImpl.getClusterView()
Key: SLING-2930
URL: https://issues.apache.org/jira/browse/SLING-2930
Project: Sling
Issue Type: Bug
Components: Extensions
Environment: any
Reporter: Adrian Nistor
The problem appears in revision 1495454. I attached a one-line patch
that fixes it.
In method "ClusterViewServiceImpl.getClusterView", the loop over
"clusterViewImpl.getInstances()" should break immediately after
"foundLocal" is set to "true". All the iterations after "foundLocal"
is set to "true" do not perform any useful work, at best they just set
"foundLocal" again to "true".
Method "isLive" in class "ResourceResolverContext" has a similar loop
(over "dynamicProviders"), and this loop breaks immediately after
"result" is set to "false", just like in the proposed patch. Other
methods (e.g., "FactoryPreconditions.checkPreconditions",
"JspUtil.checkAttributes", "EclipseJavaCompiler.compile",
"SecondPassVisitor.appendPageDirective") also have similar loops with
similar breaks, just like in the proposed patch.
