Polisher is a Ruby module and set of utilities aimed to assisting the post-publishing packaging process for Ruby gems and applications.
Provided are a series of tools geared towards querying rubygems.org and other upstream ruby sources for metadata as well as downstream sources such as the Fedora and Debian distributions to cross reference various supported stacks vendored by each.
Polisher also includes utilities to integrate and hook into various build and install workflows used by both upstream and downstream developers to synergize operations and streamline the packaging and support process.
Polisher is made available through rubygems.
Polisher dependends on the 'curb' rubygem which in return depends on the curl-devel headers. The user should install those and the development tools for their platform or install the curb gem packaged by their distribution like so:
# install the ruby & curl headers & development tools...
yum install ruby-devel libcurl-devel
yum group install "Development Tools"
# ... or install the gem manually
yum install rubygem-curb
Replace the 'yum install' commands with the corresponding ones on alternate platforms.
Various polisher subcomponents depend on various command line utilities, these include:
- /usr/bin/git - to checkout git repos
- /usr/bin/koji - to query and build against koji
- /usr/bin/yum - to query yum
- /usr/bin/md5sum - to generate required metadata
- /usr/bin/fedpkg - to query fedora
Some of these are pre-installed on many platforms and some are available via a quick 'yum install' / 'apt-get' or other. Not all are required for all utilities, see the specific executables and modules for details.
To install the latest release and all ruby dependencies simply run:
gem install polisher
See the bin/ directory for all executables available, pass '-h' to any to see specific command line options. To run any command from a local git checkout of polisher, run the following beforehand:
export RUBYLIB='lib'
A few select utilities are highlighted below.
A utility to cross reference rubygems and bundler gemfiles against various downstream resources including the koji build system, distgit (as used by Fedora), and more.
For example to check a specified ruby app for compatability in koji and yum:
gem_dependency_checker.rb --gemfile ~/myapp/Gemfile -k -y
A script that clones a rubygem maintained by distgit and update it to the latest version of the package available on rubygems (or the specified version if given). A scratch built will be run and if all goes will a commit staged so that the end user just has to 'git push' the updated package to the distro.
Simply specify the name of the gem to update like so:
git_gem_updater.rb -n rails
Alternatively if "-u" is specified with a Fedora username, all the packages the user owns will be checked out and updated.
A script that does a source comparison between a gem maintained in git against its corresponding rubygems.org gem.
Simply specify the url to the git repo and the tool will automatically detect the version of the gem to retrieve and run the diff on
git_gem_diff.rb -g https://github.com/ManageIQ/polisher.git
A tool to update a given ruby gem or application based rpm spec to the specified new source (as specified by a gem, gemspec, or gemfile).
Simply pass it the location of the spec to update, and optionally a upstream source which to update from and the utility will print out the updated spec to STDOUT.
ruby_rpm_spec_updater.rb ~/rpmbuild/SPECS/rubygem-rails.spec rails-5.0.0.gem
A tool to compare the given ruby based rpm spec against the specified source and/or the corresponding gem retrieved from rubygems.org
check_ruby_spec.rb ~/rpmbuild/SPECS/rubygem-polisher.spec
This will retrieve the gem and check the spec for consistency, reporting any discrepancies.
The core library behind these utilities, polisher provides reusable modules to query and interface with upstream ruby sources and downstream vendors and systems.
Polisher comes with complete documentation and a full test suite.
Documentation relies on the 'yard' gem / documentation system, to generate run:
rake yard
The test suite is based on rspec, to run:
rake spec
