Zenprofile 1.3.1 Released

zenprofile version 1.3.1 has been released!

zenprofiler helps answer WHAT is being called the most. spy_on helps
answer WHERE those calls are being made. ZenProfiler provides a faster
version of the standard library ruby profiler. It is otherwise pretty
much the same as before. spy_on provides a clean way to redefine a
bottleneck method so you can account for and aggregate all the calls
to it.

% ruby -Ilib bin/zenprofile misc/factorial.rb 50000
Total time = 3.056884
Total time = 2.390000

          total     self              self    total
% time  seconds  seconds    calls  ms/call  ms/call  name

ZenProfiler#start_hook

Once you know that Integer#downto takes 50% of the entire run, you
can use spy_on to find it. (See misc/factorial.rb for the actual code):

% SPY=1 ruby -Ilib misc/factorial.rb 50000
Spying on Integer#downto

Integer.downto

50000: total
50000: ./misc/factorial.rb:6:in `factorial' via
       ./misc/factorial.rb:6:in `factorial'
