[DRE-maint] Bug#918731: ruby-diaspora-vines: autopkgtest needs update for new version of rails

[Paul Gevers]

Source: ruby-diaspora-vines
Version: 0.2.0.develop.4-2
X-Debbugs-CC: debian-ci at lists.debian.org, rails at packages.debian.org

Dear maintainers,

With a recent upload of rails the autopkgtest of ruby-diaspora-vines
fails in testing when that autopkgtest is run with the binary packages
of rails from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
rails                  from testing    2:5.2.2+dfsg-1
ruby-diaspora-vines    from testing    0.2.0.develop.4-2
versioned deps [0]     from testing    from unstable
all others             from testing    from testing

I copied some of the output at the bottom of this report. It seems you
need to adapt the version to the new version of rails.

Currently this regression is contributing to the delay of the migration
of rails to testing [1]. Of course, rails shouldn't just break your
autopkgtest (or even worse, your package), but it seems to me that the
change in rails was intended and your package needs to update to the new
situation. If needed, please change the bug's severity.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from rails should really add a
versioned Breaks on the unfixed version of (one of your) package(s).
Note: the Breaks is nice even if the issue is only in the autopkgtest as
it helps the migration software to figure out the right versions to
combine in the tests.

[0] You can see what packages were added from the second line of the log
file quoted below. The migration software adds source package from
unstable to the list if they are needed to install packages from
rails/2:5.2.2+dfsg-1. I.e. due to versioned dependencies or
breaks/conflicts.
