Description William Cohen 2011-01-27 10:36:12 EST
+++ This bug was initially created as a clone of Bug #673161 +++

A number of packages have included runtime support for systemtap in Fedora such as the JVM and Python. SystemTap makes use of the probe points added for DTRACE. There are similar patches for Ruby to provide SystemTap probes for Ruby 1.9.2:

http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=26235

Older patches for Ruby 1.8.7 are available (https://gist.github.com/86895 and http://joyeur.com/2007/05/07/dtrace-for-ruby-is-available/)

An preliminary srpm based off of RHEL6 Ruby using the older 1.8.7 patches has been built and used successfully with trace Ruby program execution:

http://people.redhat.com/wcohen/ruby/ruby-1.8.7.299-6.el6.dtrace_20.src.rpm

It would be very nice to have the instrumentation points available in Ruby.
Comment 2 RHEL Product and Program Management 2011-02-01 01:22:02 EST
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
representative.

According to https://bugzilla.redhat.com/show_bug.cgi?id=673161#c3 , the license for this patch is not clear, therefore I postpone this issue for RHEL 6.2
Comment 5 Vít Ondruch 2011-06-13 11:48:16 EDT
The license should be same as Ruby's license, since it was already applied upstream and later reverted. I cannot imagine that they will publish something, request merge to Ruby with some different license.
