systemtap support for ruby
I'm not claiming this as I'm not sure I can commit the time at the moment, but I have spent some cycles on my own time porting the patch adding systemtap support to python in Fedora to Ruby
Its not complete, there are some things that still need to be done/fixed and there might be better places to put the probes (I hadn't noticed the dtrace/ruby patch before, thanks for that), but it could be used as a base for further development.
Hope this helps
First of all, - under what license are the patches for systemtap support available? - and where is the "current" patch for systemtap support for ruby 1.8.7.x? -The license isn't clear for the Ruby 1.8.7 patch that is in the prototype ruby source rpm. However, there is a 1.9.2 patch in the ruby svn: http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=26235 -The prototype rpm is available 1.8.7 patch: http://people.redhat.com/wcohen/ruby/ruby-1.8.7.299-6.el6.dtrace_20.src.rpm If Ruby in Fedora is going to be rebased to 1.9.2 (https://bugzilla.redhat.com/show_bug.cgi?id=667603) then could just use that patch in ruby svn. Otherwise back port the patch in Ruby svn to 1.8.7. Additional info.
Issue for adding dtrace support ruby:
http://redmine.ruby-lang.org/issues/1279
Issue for adding various tracing hooks to ruby:
http://redmine.ruby-lang.org/issues/2565
There were three patches to put dtrace support into ruby january 2010:
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=26235
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=26238
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=26239
However, shortly afterwards the patches were reverted with:
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=26243
The original patch for 1.8.5 and 1.8.6 si GPLv2, therefore also the 1.8.7 patch should be GPLv2 IMO. http://svn.joyent.com/opensource/dtrace/ruby/ Or better Ruby or GPLv2 There are going to be DTrace probes in Ruby 2.0 [1]. They are already implemented in ruby-2.0 branch of Ruby's dist-git [2]. [1] https://bugs.ruby-lang.org/issues/2565 [2] http://pkgs.fedoraproject.org/cgit/ruby.git/tree/?h=ruby-2.0 Since F19, there is integrated systemtap support [1]. William, since the probes differs from the RHEL ones, would you mind to update your wikipage [2]?
