Re: [jboss-dev] Further profling: Where should I focus?
I think I've got the bypassing proxy stuff working now both with and without weaving.
I'm re-running some tests before committing. A summary of what I have done;
-AOP proxy creation/checks is disabled by default
-@EnableAopProxy on a bean forces it to go through the proxy checks
-@DisableAOP is deprecated, but will stil be checked if it is present and the new
annotations are not present
A few points:
-if a bean is not woven but has constructor aspects you want invoked, the bean needs the
@EnableAopProxy annotation
-If a bean's class is woven it can have aspects, so we will always check the AOP
dependencies for that bean. This will only happen if loadtime weaving was turned on (or
compile-time weaving was used) AND the bean matches some pointcuts, so it should not be an
issue in practice.
Once I've tidied up I'll commit to MC trunk, and try putting it into AS trunk
before moving on to replacing the mechanism for AOP lifecycle.

I've made a start on this, but doubt I'll finish it before I
finish for Christmas. I am deprecating the @DisableAOP annotation. By default aop proxies
will be disabled, but can be enabled with @EnableAopProxy. Lifecycle callbacks will be
enabled by default (and I'll come up with a quicker way of determining if they should
apply), but can be disabled using the @DisableAopLifecycle annotation.
One issue that I need to look into is that there are a bunch of tests that run with
weaving enabled, so I need to see how they fare with this new setup. Since if they are
woven, aspects will apply, and if those aspects have dependencies we need those in
AOPDependencyBuilder.
