Created attachment 328094 [details] Test case for this bug. This file also contain other unrelated tests, though. Description of problem: Ruby interpreter can't handle certain short-named constants in class inheritance. This is illustrated by a Ruby test program attached. The test program is part of Metasploit Framework <http://www.metasploit.com/> by the Metasplot LLC. It does not contain any security-specific code by itself, but merely a sanity check. Version-Release number of selected component (if applicable): 1.8.6.287-2.fc10 How reproducible: Always Steps to Reproduce: 1. Run the Ruby program in the attachment. 2. 3. Actual results: The test (in function ruby_187_const_bug()) is not passed. Expected results: It should have passed. Additional info: 1. The test program, on failure, produces a banner telling the user to switch to Ruby 1.8.6 because it is believed the bug was introduced in Ruby 1.8.7. However, this of course doesn't apply for Fedora, as we are using 1.8.6. I guess the bug may be introduced when backporting from upstream's release. 2. For more information, please refer to this Ubuntu bug: https://bugs.launchpad.net/ubuntu/+source/ruby1.8/+bug/282302 3. This bug is not present in an earlier version ruby-1.8.6.230-1.fc10.
This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component.
I plan to port metacploit to fedora a need this functionality. Do you plan to rapair it?
If you feel like it, maybe you can help resolve the issue.
From the header message from the metasploit can be seen that the bug is repaired in the latest snapshot, so I think it is findable in the changelog, and backport the patch is easier than making new one. ********************************************************************** *** * *** This version of the Ruby interpreter has significant problems, we * *** strongly recommend that you switch to version 1.8.6 until these * *** issues have been corrected.

Created attachment 337229 [details] Patch from the Ubuntu bug report - Rev 18485 from upstream This patch applies to the current ruby SRPM and allows Metasploit to function properly.
Thanks, I'm rebuilding the package now and will submit to rawhide as soon as I can.
Note that current F-13/12 ruby does not seem to have this bug. ruby-1.8.6.383-4.fc11 (which will shortly be included into -testing) does not have this issue.
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
