This project **does not** use GitHub issues for questions, investigations, discussions, and so on.
Issues are appropriate for something specific enough for a maintainer or contributor to work on:
* There should be enough information to reproduce the behavior observed in a reasonable amount of time
* It should be reasonably clear why the behavior should be changed and why this cannot or should not be addressed
in application code, a separate library and so on
All issues that do not satisfy the above properties belong to the [Ruby RabbitMQ clients mailing list](http://groups.google.com/forum/#!forum/ruby-amqp). Pull request that do not satisfy them have a high chance
of being closed.
## Submitting a Pull Request
Please read the sections below to get an idea about how to run Bunny test suites first. Successfully
running all tests, at least with `CI` environment variable exported to `true`, is an important
first step for any contributor.
Once you have a passing test suite, create a branch and make your changes on it.
When you are done with your changes and all
tests pass, write a [good, detailed commit message](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html) submit a pull request on GitHub.
The project uses Bundler for dependency management and requires RabbitMQ `3.5+` to be running
locally with the `rabbitmq-management` and `rabbitmq_consistent_hash_exchange` plugins enabled.
### Running the Specs
The specs require RabbitMQ to be running locally with a specific set of vhosts
and users. RabbitMQ can be provisioned and started any way that's convenient to you
as long as it has a suitable TLS keys configuration and management plugin enabled.
Make sure you have a recent version of RabbitMQ (> `3.5.3`).
You can also start a clean RabbitMQ server
node on your machine specifically for the bunny specs.
This can be done either by using a locally installed RabbitMQ server or by
running a RabbitMQ server in a Docker container.
#### Using a locally installed RabbitMQ server
It is possible to start a local RabbitMQ node from the repository root. It is not necessarily
optimal but can be a good starting point but is a useful example:
RABBITMQ_NODENAME=bunny RABBITMQ_CONFIG_FILE=./spec/config/rabbitmq RABBITMQ_ENABLED_PLUGINS_FILE=./spec/config/enabled_plugins rabbitmq-server
The specs use the RabbitMQ management plugin and require a TLS port to
be available. The config files in the spec/config directory enable
these. TLS (x509 PEM) certificates include a hostname-specific fields,
the tests allow for expecting hostname overriding using the `BUNNY_RABBITMQ_HOSTNAME`
environment variables (default value is `127.0.0.1`).
By default there's a set of CA, server, and client certificates pre-generated at `spec/tls`. Since x509 certificates
contain a hardcoded CN and your hostname is unlikely to match it,
the location can be overridden via the `BUNNY_CERTIFICATE_DIR` environment variable.
It is supposed to target [tls-gen](https://github.com/michaelklishin/tls-gen)'s basic profile
output (result) directory on the host where specs are to be executed. Combine it with `BUNNY_RABBITMQ_HOSTNAME`
when running TLS connection tests:
BUNNY_CERTIFICATE_DIR="/path/to/tls-gen/basic/result" BUNNY_RABBITMQ_HOSTNAME="mayflower" bundle exec rspec
Next up you'll need to prepare your node for the specs (just once):
The script uses `rabbitmqctl` and `rabbitmq-plugins`
to set up RabbitMQ in a way that Bunny test suites expect. Two environment variables,
`RABBITMQCTL` and `RABBITMQ_PLUGINS`, are available to control what `rabbitmqctl` and
`rabbitmq-plugins` commands will be used. By default they are taken from `PATH`
and prefixed with `sudo`.
And then run the core integration suite:
RABBITMQ_NODENAME=bunny CI=true rspec
#### Running a RabbitMQ server in a Docker container
First off you have to [install Docker Compose](https://docker.github.io/compose/install/) (and by proxy Docker).
Version >= 1.6.0+ is required for compose version 2 syntax.
After those have been installed (and the `docker-compose` command is available on your command line path), run
The first time you do this, it will take some time, since it has to download everything it needs
to build the Docker image.
The RabbitMQ server will run in the foreground in the terminal where you started it. You can stop
it by pressing CTRL+C. If you want to run it in the background, run `docker-compose up -d`.
### Running Test Suites
Prior to running the tests, configure the RabbitMQ permissions by running `./bin/ci/before_build`
if you have RabbitMQ locally installed, if you are running RabbitMQ via Docker as above this step
is not required as the setup is baked in.
Make sure you have those two installed and then run integration tests:
It is possible to run all tests:
bundle exec rspec
It is possible to run only integration and regression tests but exclude unit and stress tests:
CI=true bundle exec rspec spec/higher_level_api/ spec/lower_level_api spec/issues spec/higher_level_api/integration/connection_recovery_spec.rb
