running "ruby" inside a rake task ignores JRUBY_OPTS
----------------------------------------------------
Key: JRUBY-5650
URL: http://jira.codehaus.org/browse/JRUBY-5650
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6
Environment: Ubuntu Linux, running jRuby under RVM
Reporter: Gonçalo Silva
Assignee: Thomas E Enebo
I have a script called "works.rb". It's code is pretty simple:
{quote}
require 'jruby/profiler'
profile_data = JRuby::Profiler.profile do
1000.times do |n| Hash.new end
end
profile_printer = JRuby::Profiler::GraphProfilePrinter.new(profile_data)
profile_printer.printProfile(STDOUT)}}
{quote}
If I run {{export JRUBY_OPTS="--profile.api" && ruby works.rb}} everything
works as expected. Here's the output:
{quote}
Profiling enabled; ^C shutdown will now dump profile info
Total time: 0.02
%total %self total self children calls name

However, JRUBY_OPTS gets ignored when running "works.rb" inside a rake task. I
have the following Rakefile:
{quote}
task :fails do
ruby "works.rb"
end
{quote}
Running {{export JRUBY_OPTS="--profile.api" && rake fails}} returns:
{quote}
Profiling enabled; ^C shutdown will now dump profile info
(in /home/goncalossilva/Desktop)
** Invoke fails (first_time)
** Execute fails
/home/goncalossilva/.rvm/rubies/jruby-1.6.0/bin/jruby works.rb
Total time: 0.00
