Small helpers that do not warrant their own library.

Notable helpers
---------------

  - init_logging (libadvian.logging): Initializes default logger to our standard log format
  - b64_to_uuid and uuid_to_b64 (libadvian.binpackers): URL-safe base64 UUID decode/encode
  - ensure_[utf8|str] (libadvian.binpackers): For making sure you are dealing with bytes or strings.

There is more, everything is type hinted and documented, just look around.

Docker
------

For more controlled deployments and to get rid of "works on my computer" -syndrome, we always
make sure our software works under docker.

It's also a quick way to get started with a standard development environment.

SSH agent forwarding
^^^^^^^^^^^^^^^^^^^^

We need buildkit_::

    export DOCKER_BUILDKIT=1

.. _buildkit: https://docs.docker.com/develop/develop-images/build_enhancements/

And also the exact way for forwarding agent to running instance is different on OSX::

    export DOCKER_SSHAGENT="-v /run/host-services/ssh-auth.sock:/run/host-services/ssh-auth.sock -e SSH_AUTH_SOCK=/run/host-services/ssh-auth.sock"

and Linux::

    export DOCKER_SSHAGENT="-v $SSH_AUTH_SOCK:$SSH_AUTH_SOCK -e SSH_AUTH_SOCK"

Creating a development container
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Build image, create container and start it::

    docker build --ssh default --target devel_shell -t libadvian:devel_shell .
    docker create --name libadvian_devel -v `pwd`":/app" -it `echo $DOCKER_SSHAGENT` libadvian:devel_shell
    docker start -i libadvian_devel

pre-commit considerations
^^^^^^^^^^^^^^^^^^^^^^^^^

If working in Docker instead of native env you need to run the pre-commit checks in docker too::

    docker exec -i libadvian_devel /bin/bash -c "pre-commit install"
    docker exec -i libadvian_devel /bin/bash -c "pre-commit run --all-files"

You need to have the container running, see above. Or alternatively use the docker run syntax but using
the running container is faster::

    docker run --rm -it -v `pwd`":/app" libadvian:devel_shell -c "pre-commit run --all-files"

Test suite
^^^^^^^^^^

You can use the devel shell to run py.test when doing development, for CI use
the "tox" target in the Dockerfile::

    docker build --ssh default --target tox -t libadvian:tox .
    docker run --rm -it -v `pwd`":/app" `echo $DOCKER_SSHAGENT` libadvian:tox

Development
-----------

TLDR:

- Create and activate a Python 3.7 virtualenv (assuming virtualenvwrapper)::

    mkvirtualenv -p `which python3.7` my_virtualenv

- change to a branch::

    git checkout -b my_branch

- install Poetry: https://python-poetry.org/docs/#installation
- Install project deps and pre-commit hooks::

    poetry install
    pre-commit install
    pre-commit run --all-files

- Ready to go.

Remember to activate your virtualenv whenever working on the repo, this is needed
because pylint and mypy pre-commit hooks use the "system" python for now (because reasons).
