A test case for Gem::Installer
.
# File rubygems/installer_test_case.rb, line 66 def setup super Gem::Installer.path_warning = false end
Creates the following instance variables:
a spec named 'a', intended for regular installs
And returns a gem built for the @spec
# File rubygems/installer_test_case.rb, line 124 def setup_base_gem @spec = setup_base_spec util_build_gem @spec @spec.cache_file end
Creates the following instance variables:
a spec named 'a', intended for regular installs
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 111 def setup_base_installer(force = true) @gem = setup_base_gem util_installer @spec, @gemhome, false, force end
Sets up a generic specification for testing the rubygems installer
And returns it
# File rubygems/installer_test_case.rb, line 135 def setup_base_spec quick_gem 'a' do |spec| util_make_exec spec end end
Creates the following instance variables:
a spec named 'a', intended for regular installs
a spec named 'b', intended for user installs
the path to a built gem from @spec
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 156 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
This is needed for Windows environment without symlink support enabled (the default for non admin) to be able to skip test for features using symlinks.
# File rubygems/installer_test_case.rb, line 235 def symlink_supported? if @@symlink_supported.nil? begin File.symlink("", "") rescue Errno::ENOENT, Errno::EEXIST @@symlink_supported = true rescue NotImplementedError, SystemCallError @@symlink_supported = false end end @@symlink_supported end
The path where installed executables live
# File rubygems/installer_test_case.rb, line 75 def util_inst_bindir File.join @gemhome, "bin" end
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 224 def util_installer(spec, gem_home, user=false, force=true) Gem::Installer.at(spec.cache_file, :install_dir => gem_home, :user_install => user, :force => force) end
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 85 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
Builds the @spec gem and returns an installer for it. The built gem includes:
bin/executable lib/code.rb ext/a/mkrf_conf.rb
