I am wondering if we should mention Bundler in Ruby's packaging guidelines and what should be recommendations? Or should we leave it in gray area of guidelines?
The root issue isn't using bundler per-se, rather the gem dependencies listed in the rpm spec, gem spec, and bundler's Gemfile may become out of sync.
So long as the guidelines has something to address this I think we'll be fine. Something along the lines of it is up to the package maintainer to ensure all the gem dependency subsystems (rpm, gem, and bundler) are kept in sync.
I am afraid of scenario such as:
* Having RPM packaged Rails application
* Having Gemfile.lock present
* Update of Rack to 1.4 version.
Now how you will ensure after such update that you did not broke the application? Even though you can find what packages depends on Rack and you check their .gemspec, how you will find the applications with Gemfile.lock? How you will find packages where Gemfile states 'rack', '1.3'?
If the rpm spec, gemspec, and gemfile are required to be kept in sync, this isn't an issue.
The maintainer of the rails application would need to represent all their dependencies in the rpm spec and the Gemfile lock. Afterall they best know what the various versions of their application require in terms of the various versions of underlying dependencies, and can update their package accordingly (to make it is as restrictive or as flexible as desired).
In this case, trying to update Rack would break things at both the rpm level, the gem level, and the bundler level. Thus first and foremost the system wouldn't permit it if doing the update via rpm, and if doing it via gem / bundler, it wouldn't matter as the rpm version would still be present.
If you update rack, you should ensure that you did not broken the activesupport (possibly fixing its .gemspec and may be some failures).
Why? Nowhere else in Fedora is a package maintainer required to make sure that all the dependencies on that package do not break with an update.
Rather, the policy is to keep versions stable within a Fedora release, and if a major package is being updated in a new release, to give plenty of notification via the mailing lists and what not.
Jeroen is the owner or rubygem-rack, I am the owner of rubygem-activesupport. If he wishes to update rack in the next version of Fedora he should announce on the ruby-sig mailing list this upcoming update, making the rpms available as soon as he can (either hosted by himself or via rawhide), and it is up to me to make sure rubygem-activesupport doesn't break.
If I need to update activesupport to ensure this, I should do the same, eg announce on list and make the rpms available. This way the community is kept in sync and we can discuss updates / resolve issues before hand.
