Re: Does RubyProf::ALLOCATIONS work on 1.9.x??

[Mark Corner]

I am guessing that it is related to this bug here:

https://github.com/rdp/ruby-prof/issues/86

Which seems to completely prevent memory profiling on 1.9.2, 1.9.3, and possibly others.

I am trying to get ALLOCATIONS to be profiled on 1.9.2 or 1.9.3  I have tried this on stock ruby, ruby with the gcdata patch and on the railsexpress ruby patches.  No luck...  I always just get output that looks exactly like the default CPU time output.  I am assuming I can get allocations broken down by call stack.

Is this a known problem or amI doing something dumb??

require 'ruby-prof'

RubyProf::measure_mode = RubyProf::MEMORY

# Profile the code

RubyProf.start

a=[]

20000.times{

        a << rand

}

result = RubyProf.stop

#printer = RubyProf::GraphPrinter.new(result)

printer = RubyProf::CallStackPrinter.new(result)

printer.print(STDOUT)
