[jira] [Created] (SLING-2927) Wasted work in
ValidateVisitor.isExpression()
Adrian Nistor created SLING-2927:
------------------------------------
Summary: Wasted work in ValidateVisitor.isExpression()
Key: SLING-2927
URL: https://issues.apache.org/jira/browse/SLING-2927
Project: Sling
Issue Type: Bug
Components: Scripting
Environment: any
Reporter: Adrian Nistor
The problem appears in version 6 and in revision 1495454. I attached
a two-line patch that fixes it.
In method "ValidateVisitor.isExpression", the loop over "nodes" should
break immediately after "elExpression" is set to "true". All the
iterations after "elExpression" is set to "true" do not perform any
useful work, at best they just set "elExpression" 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.
