Start using MODRUBY_REGRESS with ruby, rspec2, and testrb entries.
Switch away from manual do_regress targets where possible. Add
some patches to make regress tests run for some ports.
ruby-prof is a fast code profiler for Ruby. Its features include:
* Speed - it is a C extension and therefore many times faster than the
standard Ruby profiler.
* Modes - Ruby prof can measure a number of different parameters,
including call times, memory usage and object allocations.
* Reports - can generate text and cross-referenced html reports
o Flat Profiles - similar to the reports generated by the standard
Ruby profiler
o Graph profiles - similar to GProf, these show how long a method
runs, which methods call it and which methods it calls.
o Call tree profiles - outputs results in the calltree format
suitable for the KCacheGrind profiling tool.
* Threads - supports profiling multiple threads simultaneously
* Recursive calls - supports profiling recursive method calls
