RealmBase.java Log: First attempt to get Tomcat compliant with the
Servlet 2.4 Spec for AA.
This one isn't very efficient (but not much worse than it was before :). Longer term, I'm looking to modify the j-t-c mapper to be able to return a Collection of mapped objects, and use that. In that case it could also be used for Filter mappings.
Filter mapping is simple, and should be efficient enough right now. It was really horrible in 4.1.x (except if somehow all filters are mapped to /* or the exact path :-D), and is obviously used a lot more in 5.0.x, so I did fix it. I was planning to use something fancy when I noticed the requirements for this algorithm:
- we have try all the mappings in order, which voids any possible optimization
- I think we only have a String at our disposal for filter mapping: getting a char array would remove any performance benefit
- we don't have to generate any paths or similar stuff from the mapping results
- there was this regionMatches method in String that could do that matching test efficiently
And the profiler seems happy :) Maybe it's lying though.
For the contraint mapping, since we also have to test them all and return yes/no for each, I recommend using a similar custom algorithm.
This version is just to get a Spec compliant version out there that can be tested.
