Summary: RubyGems Plugins: odd behavior when gem w/ plugin has multiple
installed versions.
Initial Comment:
When I run gem rdoc with multiple copies of yard installed, I get a
SystemStackError because each version of yard installed's rubygems_plugin.rb
file is loaded. I think that rubygems shouldn't load the rubygems_plugin.rb
files for all installed versions of a gem, it should only load the latest
version of the plugins.
$ sudo gem rdoc sinatra --backtrace
ERROR: While executing gem ... (SystemStackError)
stack level too deep
/usr/lib/ruby/gems/1.8/gems/yard-0.5.2/lib/rubygems_plugin.rb:19:in `has_rdoc?'
/usr/lib/ruby/gems/1.8/gems/yard-0.4.0/lib/rubygems_plugin.rb:77:in
`install_ri_yard_orig'
/usr/lib/ruby/gems/1.8/gems/yard-0.4.0/lib/rubygems_plugin.rb:77:in

/usr/lib/ruby/gems/1.8/gems/yard-0.5.2/lib/rubygems_plugin.rb:79:in `install_ri'
/usr/local/lib/site_ruby/1.8/rubygems/doc_manager.rb:109:in `generate_ri'
...
yard's maintainer has added a fix, but it only works going forward(since
Gem.find_files returns the newer one first).
I wrote something that fixes the problem by replacing /lib/rubygems.rb:1103,
but it is kind of ugly due to my unfamiliarity with rubygems internals.
plugins = Gem.latest_load_paths.map do |path|
path = path+'/rubygems_plugin.rb'
path if File.exists? path
end.compact
my notes are also at http://gist.github.com/281456
Thanks,
Nick Howard
