setup() click to toggle source

Calls superclass method Gem::TestCase#setup

# File rubygems/installer_test_case.rb, line 69
def setup
  super

  Gem::Installer.path_warning = false
end

setup_base_gem() click to toggle source

Creates the following instance variables:

@spec: a spec named ‘a’, intended for regular installs

And returns a gem built for the @spec

# File rubygems/installer_test_case.rb, line 127
def setup_base_gem
  @spec = setup_base_spec
  util_build_gem @spec
  @spec.cache_file
end

setup_base_installer() click to toggle source

Creates the following instance variables:

@spec: a spec named ‘a’, intended for regular installs
@gem: the path to a built gem from @spec

And returns a Gem::Installer for the @spec that installs into @gemhome

# File rubygems/installer_test_case.rb, line 114
def setup_base_installer
  @gem = setup_base_gem
  util_installer @spec, @gemhome
end

setup_base_spec() click to toggle source

Sets up a generic specification for testing the rubygems installer

And returns it

# File rubygems/installer_test_case.rb, line 138
def setup_base_spec
  quick_gem 'a' do |spec|
    util_make_exec spec
  end
end

setup_base_user_installer() click to toggle source

Creates the following instance variables:

@spec: a spec named ‘a’, intended for regular installs
@user_spec: a spec named ‘b’, intended for user installs
@gem: the path to a built gem from @spec
@user_gem: the path to a built gem from @user_spec

And returns a Gem::Installer for the @user_spec that installs into Gem.user_dir

# File rubygems/installer_test_case.rb, line 159
def setup_base_user_installer
  @user_spec = quick_gem 'b' do |spec|
    util_make_exec spec
  end

  util_build_gem @user_spec

  @user_gem = @user_spec.cache_file

  util_installer @user_spec, Gem.user_dir, :user
end

util_inst_bindir() click to toggle source

The path where installed executables live

# File rubygems/installer_test_case.rb, line 78
def util_inst_bindir
  File.join @gemhome, "bin"
end

util_installer(spec, gem_home, user=false) click to toggle source

Creates an installer for spec that will install into gem_home. If user is true a user-install will be performed.

# File rubygems/installer_test_case.rb, line 227
def util_installer(spec, gem_home, user=false)
  Gem::Installer.at(spec.cache_file,
                     :install_dir => gem_home,
                     :user_install => user)
end

util_make_exec(spec = @spec, shebang = " click to toggle source

Adds an executable named “executable” to spec with the given shebang.

The executable is also written to the bin dir in @tmpdir and the installed gem directory for spec.

# File rubygems/installer_test_case.rb, line 88
def util_make_exec(spec = @spec, shebang = "#!/usr/bin/ruby", bindir = "bin")
  spec.executables = %w[executable]
  spec.bindir = bindir

  exec_path = spec.bin_file "executable"
  write_file exec_path do |io|
    io.puts shebang
  end

  bin_path = File.join @tempdir, "bin", "executable"
  write_file bin_path do |io|
    io.puts shebang
  end
end

util_setup_gem(ui = @ui) { |spec| ... } click to toggle source

Builds the @spec gem and returns an installer for it. The built gem includes:

bin/executable
lib/code.rb
ext/a/mkrf_conf.rb

# File rubygems/installer_test_case.rb, line 188
  def util_setup_gem(ui = @ui)
    @spec.files << File.join('lib', 'code.rb')
    @spec.extensions << File.join('ext', 'a', 'mkrf_conf.rb')

    Dir.chdir @tempdir do
      FileUtils.mkdir_p 'bin'
      FileUtils.mkdir_p 'lib'
      FileUtils.mkdir_p File.join('ext', 'a')

      File.open File.join('bin', 'executable'), 'w' do |f|
        f.puts "raise 'ran executable'"
      end

      File.open File.join('lib', 'code.rb'), 'w' do |f|
        f.puts '1'
      end

      File.open File.join('ext', 'a', 'mkrf_conf.rb'), 'w' do |f|
        f << <<-EOF
          File.open 'Rakefile', 'w' do |rf| rf.puts "task :default" end
        EOF
      end

      yield @spec if block_given?

      use_ui ui do
        FileUtils.rm_f @gem

        @gem = Gem::Package.build @spec
      end
    end

    Gem::Installer.at @gem
  end

util_setup_installer() click to toggle source
