---------------------------------------
Summary: [perf] Use ResourceLoaderCache for
ResourceHandler.libraryExists(...)
Key: MYFACES-3954
URL: https://issues.apache.org/jira/browse/MYFACES-3954
Project: MyFaces Core
Issue Type: Improvement
Components: JSR-344
Reporter: Leonardo Uribe
Assignee: Leonardo Uribe
Priority: Minor
Thinking about some stuff for JSF 2.3 and checking how ResourceHandler is
implemented, I notice the call to ResourceHandler.libraryExists(...) does not
take advantage of ResourceLoaderCache and instead call every ResourceLoader and
ContractResourceLoader. The problem is these loaders has some calls that are
slow, while a cache lookup can be fast.
Most of the time. ResourceHandler.libraryExists(...) is called when a facelet
is compiled and it requires a composite components. Since there is already a
cache for compiled facelets, the impact is seen only when the facelet is
compiled, but this step is done for every facelet that makes a reference to the
same composite component.
It is a minor improvement, but it will improve the speed of the compilation
step.
