You should notice some version numbers. That's also a new addition and every week I will deploy a new version, so eventually at some point in the end of the summer, version 1.0.0 will be released.

Here are some nice stats from git log.

Git stats: 91 commits / 4,662 ++ / 2,874 --

Rails/Ruby style guide

Fixed arround 500 warnings that rubocop yielded.


Added: unit tests for models.

Missing: A bunch of code still needs testing, rspec is not enough to properly test api calls. I will use vcr and webmock in the future to cover these tests. Integration tests are also not complete yet.

Bugs fixed

wrong owners

Previously it parsed the spec file and checked the first email in the changelog. Co-maintainers have also the ability to build a package and in that case it shows wrong info. Another case is where a user changes their email they are taken into account twice, so when hitting /by_owner not all packages are shown. I was hit by this bug.

It now fetches the owner's fas name using pkgwat which I use to sort by owner.

dependencies shown twice

The current implementation scraps the SPEC file of a rubygem via the gitweb and then stores the dependencies. The problem is that when one uses gem2rpm, ~> is expanded to >= and <=, which leads to list some dependencies twice.

Double dependencies

The fix was quite easy. Here is the controller that is in charge for the show action:

  def show
    @name = params[:id]
    @rpm = FedoraRpm.find_by_name! @name
    @page_title = @rpm.name
    @dependencies = @rpm.dependency_packages.uniq
    @dependents = @rpm.dependent_packages.uniq
    rescue ActiveRecord::RecordNotFound
      redirect_to action: 'not_found'

All I did was to add uniq.

duplicate homepage and source uri

In a gem page you could see this:

Double homepage

The information is taken from the https://rubygems.org api. Some have the same page for both gem's homepage and source uri. The secret was lying in the [view][].

  %h3 Gem Information
    =link_to @gem.homepage, @gem.homepage
  - unless @gem.source_uri.blank?
      Source Code:
      =link_to @gem.source_uri, @gem.source_uri

All I did was to change this from this:

- unless @gem.source_uri.blank?

to this:

- unless @gem.source_uri.blank? || @gem.source_uri == @gem.homepage

So now it skips showing the homepage if it is the same as the source uri.


Show more info in fedorarpm show page

I added some more information at the fedorarpm page. Now it shows, last packager, last commit message and last commit date. Useful if something is broken with the latest release and you want to blame someone :p

And since many times a package has many co-maintainers you get to see the real last packager.

Here's a shot of the page as it is now:

More info

Rake tasks

As I have made some major refactoring in the fedorarpms model, I split many methods to their own namespace. For example, previously there was a single method for importing the versions and dependencies, now they are two separate.

As a consequense, I added rake tasks that could be invoked for a single package. Also the namespace is now more descriptive.

The tasks are for now the following:

rake fedora:gem:import:all_names               # FEDORA | Import a list of names of ALL gems from rubygems.org
rake fedora:gem:import:metadata[number,delay]  # FEDORA | Import gems metadata from rubygems.org
rake fedora:gem:update:gems[age]               # FEDORA | Update gems metadata from rubygems.org
rake fedora:rawhide:create                     # FEDORA | Create file containing Fedora rawhide(development) version
rake fedora:rawhide:version                    # FEDORA | Get Fedora rawhide(development) version
rake fedora:rpm:import:all[number,delay]       # FEDORA | Import ALL rpm metadata (time consuming)
rake fedora:rpm:import:bugs[rpm_name]          # FEDORA | Import bugs of a given rubygem package
rake fedora:rpm:import:commits[rpm_name]       # FEDORA | Import commits of a given rubygem package
rake fedora:rpm:import:deps[rpm_name]          # FEDORA | Import dependencies of a given rubygem package
rake fedora:rpm:import:gem[rpm_name]           # FEDORA | Import respective gem of a given rubygem package
rake fedora:rpm:import:koji_builds[rpm_name]   # FEDORA | Import koji builds of a given rubygem package
rake fedora:rpm:import:names                   # FEDORA | Import a list of names of all rubygems from apps.fedoraproject.org
rake fedora:rpm:import:versions[rpm_name]      # FEDORA | Import versions of a given rubygem package
rake fedora:rpm:update:oldest_rpms[number]     # FEDORA | Update oldest <n> rpms
rake fedora:rpm:update:rpms[age]               # FEDORA | Update rpms metadata

That was it for now. For any changes be sure to check out the changelog regularly!
