A while back, I wrote about creating your own gem server – which basically consisted of custom building a
sources gem. Mainly because
gem sources --remove at the time wouldn’t let you remove rubyforge from the sources list.
gem sources --remove now works great. And with RubyGems 0.9.5 – they’ve included a new
gem generate_index command that will generate the indexes for you. So now – if you want to create your own gem server, you can run the web server software of your choice and use the
gem generate_indixe -d [docroot]/mycoolgems command to build the indexes.
(If you do update the rubygems-update gem on your “client” systems, make sure to do a
gem sources --add http://yourgemserver and a
gem sources --remove http://gems.rubyforge.org from your sources. Or continue building your own sources gem.)
Unfortunately, through no fault of the RubyGems devs, this might not work on a system running Ruby 1.8.5 – like, say, Red Hat Enterprise Linux, version 5. The fault lies in Ruby itself.
gem generate_index builds its index in /tmp – and uses FileUtils to move it out of /tmp and into the place you specified as the target directory (or ‘.’). If your servers are like mine, /tmp and your web server directories are on different partitions, and unfortunately FileUtils in Ruby 1.8.5 has a bug moving directories across partitions.
The bug was fixed, I think with this revision in March 2007 – and it’s in Ruby 1.8.6 (at least as of p110/111) – but it’s not in Red Hat’s 1.8.5 packages – and I’m not sure it qualifies as a security bug, so I doubt it will get backported.
Anyway, I went the configure/make/make install route (package purists, feel free to cringe, but I don’t want to make RPM’s and this is core enough for me to stay on top of). Your mileage may vary.
