rubygems: bad urls

[Marc Weber]

I patched ruby gems successfully so that it outputs ruby packages so
that I can feed them into the Nix package manager system
(www.nixos.org).

One item of the generated output looks like this:

jeremymcanally_pending_0_1 = rubyDerivation {
name = "ruby-jeremymcanally-pending-0.1"; # full_name
nameNoVersion = "jeremymcanally_pending";
propagatedBuildInputs = [ ];
src = fetchurl {
url = "http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem";
sha256 = "no hash";
};
meta = {
homepage = "http://jeremymcanally.com";
license = []; # one of ?
description = "pending lets you define a block of test code that is currently \"pending\" functionality, similar to RSpec's pending method"; # cut to 120 chars
longDescription = "pending lets you define a block of test code that is currently \"pending\" functionality, similar to RSpec's pending method.";
};
};


And you can see by "no hash" that something is wrong with this gem. It's
not only that one. By resolving dependencies for:

up chronic rubygems-update xrefresh-server rb-inotify jeweler


these .gem urls are invalid:

http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem
http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem
http://gems.rubyforge.org/gems/devver-construct-1.1.0.gem
http://gems.rubyforge.org/gems/mhennemeyer-output_catcher-1.0.1.gem
http://gems.rubyforge.org/gems/thoughtbot-shoulda-2.10.2.gem
http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem
http://gems.rubyforge.org/gems/jeremymcanally-pending-0.1.gem
http://gems.rubyforge.org/gems/devver-construct-1.1.0.gem
http://gems.rubyforge.org/gems/mhennemeyer-output_catcher-1.0.1.gem
http://gems.rubyforge.org/gems/thoughtbot-shoulda-2.10.2.gem

So what's happening here?
Of course I can start fetching those gems manually from git repositories
etc. But isn't the purpose of gems that I can install them easily ?

Should I contact the authors and ask them to upload a new version?
Actually I have kind of bootstrapping problem: I'd like to use rake to
build the gem files. However rake requires jeweler. I can't install
jeweler because of bad hashs.

Is there a way to fix those gem urls?

Yes, I am new to ruby.

Gems are hosted on gemcutter.org by now, not RubyGems.

Gems are hosted on gemcutter.org by now, not RubyGems.

gems.rubyforge.org == gemcutter.org

"Hosted" has nothing to do with "downloading"

The above URLs:

http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem

Are simple redirects to Amazon S3/CDN hosted files:


curl --head http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem

If Nix cannot resolve over redirects, then you will need to indicate
the CDN location.

It can. However shouldn't I be able to download this gem by copy pasting
this url into any browser?
http://gems.rubyforge.org/gems/bmabey-fakefs-0.1.1.1.gem
-> http://production.cf.rubygems.org/gems/bmabey-fakefs-0.1.1.1.gem
Fine. Follow the next redirect as well, please:

Connection: close

So access is forbidden. Thus the link is broken.
Redirection does work fine for many other .gem packages.
