* Use fastARef/fastASet for hash access to avoid context load. * Cache most Java strings used to create headers as ByteLists, to avoid re-encoding and re-constructing the byte[] and ByteList. * Load parse buffer once in field handler. * Eliminate deprecated construction of RaiseException and centralize logic.
Seven fewer objects and no eager lookup of the exception class.

Note: This PR does not include the changes from #2010. That patch may not apply cleanly over this one but it's a trivial change. |
There's only ever one implementation of these, so just call them directly.

This PR contains a quick pass over the Http11 class and the generated parser to reduce allocation and other antipatterns.
runtimeandparserfields by passing them into callbacks.The callbacks could also be made into Java lambdas, removing the anonymous classes from the jar file, but that would tie this code to Java 8 or higher. I believe there may still be some JRuby folks with legacy apps on JRuby 1.7 + Java 7. Lambdas versus anon classes would not make any performance difference here.
