[xmlvm-users] No dependence on NSAutoreleasePool

[Arno P. <ar...@pu...>]

Guys,

I have just committed a patch submitted by Joshua Melcon. His patch 
removes the dependency on NSAutoreleasePool during code generation. 
NSAutoreleasePool is a convenience class for Objective-C programmers to 
defer releases on object references to a later time. So far we have made 
heavy use of NSAutoreleasePool (every method had its own 
NSAutoreleasePool). Unfortunately, NSAutoreleasePool is very runtime 
inefficient. Joshua's patch removes this dependency by computing where 
release and retains need to be inserted. This should dramatically 
improve runtime performance of the code generated by XMLVM.

Please update your copies of XMLVM and try your applications. If there 
are problems, please report back on the mailing list. Joshua will 
continue with some further optimizations (currently there are some 
redundant retain/release in the generated code).

Note: this change has *no* impact on the ownership rules when passing 
object references as input arguments or when returning an object 
reference as a result. Newly created instances should not be added to a 
NSAutoreleasePool.
