Can't list older gems

I'm the developer of a "meta-build-system", autoproj. At some point, it tries to fetch the available versions of a gem to check if it should be updated. However, rubygems.org only returns the latest gem and not the older ones, i.e. if I give a version spec, GemFetcher will tell me that no version is available, and autoproj will return an error.

I'll add a workaround for that in autoproj, but shouldn't rubygems.org list all the available gems

    I can't reproduce, can you show any code?

    $ gem list -ra rake$
    
    *** REMOTE GEMS ***
    
    rake (0.8.7, 0.8.6, 0.8.5, 0.8.4, 0.8.3, 0.8.2, 0.8.1, 0.8.0, 0.7.3, 0.7.2, 0.7.1, 0.7.0, 0.6.2, 0.6.0, 0.5.4, 0.5.3, 0.5.0, 0.4.15, 0.4.14, 0.4.13, 0.4.12, 0.4.11, 0.4.10, 0.4.9, 0.4.8)

    Mm... replied by email but it did not end up there ...

    From your answer, I could find what I was doing wrong.

    The issue (and I don't know if it is a bug, a known limitation or a feature) is that SpecFetcher#find_matching, when 'all' is set to false, will return an empty set when given constraints that do not match the newest gem, even though there are gems that match the constraint.

    I.e., in the general case, if you give constraints, also set 'all' to true.

    I was not expecting that, but I guess it can be seen as an acceptable limitation of #find_matching
