Environment: Linux Mint 32 bit, JRuby-1.6.5 [i386], Rails 3.1.3.
I am trying to profile a rails application deployed on JRuby 1.6.5 on WEBrick (in development mode).
My JRUBY_OPTS: "-Xlaunch.inproc = false -profile.flat"
In one of my models, I introduced explicit sleep (5) and made sure that this method is called the hook before_save part when saving the model. Pseudo code ...
class Invoice < ActiveRecord::Base <some properties here...> before_save :delay private def delay sleep(5) end end
The above code ensures that before the Invoice instance is saved, the delay method will be called automatically.
Now, when I look at the code that creates an instance of this model (via rspec unit test), I get the following output:
6.31 0.00 6.31 14 RSpec::Core::ExampleGroup.run 6.30 0.00 6.30 14 RSpec::Core::ExampleGroup.run_examples 6.30 0.00 6.30 1 RSpec::Core::Example#run 6.30 0.00 6.30 1 RSpec::Core::Example#with_around_hooks 5.58 0.00 5.58 1 <unknown> 5.43 0.00 5.43 2 Rails::Application::RoutesReloader#reload! 5.00 0.00 5.00 1 <unknown> 5.00 5.00 0.00 1 Kernel#sleep 4.87 0.00 4.87 40 ActiveSupport.execute_hook 4.39 0.00 4.39 3 ActionDispatch::Routing::RouteSet#eval_block 4.38 0.00 4.38 2 Rails::Application::RoutesReloader#load_paths
In the above example why I see these two elements instead of Invoice.delay or something like that.
In fact, when I start my rails server (WEBrick) with the same JRUBY_OPTS (mentioned above), all frames of the application code are displayed as unknown elements at the output of the profiler!
Am I doing something wrong?
