Version 9.4 hasn't been maintained since February 2020, so we aren't
supporting it either. And we might start using `UPSERT` instead of
`find_or_create`, which was introduced in PostgreSQL 9.5.
We're still supporting PostgreSQL 9.5 even if it's also unmaintained
because it has only been officially unmaintained for a couple of months.
This way developers can run the checks on their machines and using
`bundle exec` we guarantee the right versions of all our gems are being
used; with Hound we can only use the versions supported by their
service.
When including the pronto-erb_lint gem, we're getting errors in
development where our ERB does not follow the conventions Better HTML
expects. Since we only use Better HTML because ERB Lint depends on it,
and right now we are not ready to follow its conventions, we're
disabling it.
Note pronto depends on rugged, which requires CMake and pkg-config to
build the `libgit2` library it depends on. CMake and pkg-config are
installed by default in some GNU/Linux distributions like Ubuntu, but
might not be installed on other systems, so we're adding them as
development dependencies.
Using GitHub Actions has a few advantages over using Travis CI:
* More jobs can be run in parallel
* All CONSUL repositories on GitHub will be configured automatically
Besides, Travis have recently changed their policy twice. First, they
announced their site for free software projects would be shut down but
free software projects could still use their site for private projects.
And then, they limited the usage of their services for free software
projects.
Just like we used to do with Travis, we're enabling builds for pull
requests but not for pushed branches.
We're also building the master branch. Even if we never push to the
master branch directly, we're aware other CONSUL repositories do, so
we're running the tests for this case.
Why:
* Try to make the repo more friendly for first time contributors and any contributor on general
How:
* Adding a PRs-welcom badget that links to the issues list filtered by PRs-welcome label
* Adding a Link to on the Contributing guide to a free course about Pull Request and Contributions on Github.
