This is a short guide to help you get started with Postorius development.
Development Workflow
The source code is hosted on GitLab, which means that we are using Git for version control.
Changes are not made directly in the project’s master branch, but in feature-related personal branches, which get reviewed and then merged into the master branch. There is a contribution guide here, that mentions the basics about contributing to any mailman project.
An ideal workflow would be like this:
  1. File a bug to suggest a new feature or report a bug (or just pick one of the existing bugs).
  2. Create a new branch with your code changes.
  3. Make a “merge request” to get your code reviewed and merged.
First Contributions / Coverage Reports
If you don’t know how you can contribute, writing tests is a good way to get you started.
You can start by exploring the existing test coverage and finding code that’s not covered ie. not tested.
Installing and running the tests
After checkout you can run the tests using tox:
$ tox
By default this will test against a couple of different environments. If you want to only run the tests in a specific environment or a single module, you can specify this using the -e option and/or a double dash:
# List all currently configured envs: $ tox -l py35-django111 py35-django20 py35-djangolatest py36-django111 py36-django20 py36-djangolatest py37-django111 py37-django20 py37-djangolatest pep8 # Test Django 2.1 on Python3.7 only: $ tox -e py37-django21 # Run only tests in ``test_address_activation``: $ tox -- postorius.tests.test_address_activation # You get the idea... $ tox -e py37-django21 -- postorius.tests.test_address_activation
All test modules reside in the postorius/src/postorius/tests directory. Please have a look at the existing examples.
Calling Mailman’s REST API
A lot of Postorius’ code involves calls to Mailman’s REST API (through the mailmanclient library). Postorius’ test uses pytest along with pytest-django to run tests.
Postorius uses pytest fixtures to setup Mailman Core’s REST API and is defined at postorius.tests.mailman_api_tests.conftest.mailman_rest_layer​. It is set to autouse=True so, all the tests inside the module mailman_api_tests automatically use it.
mailman_rest_layer starts up incoming runner and rest runner using mailman.testing.helpersTestableMaster​. It also removes all the data after every TestCase class.
View Authorization
Three of Django’s default User roles are relevant for Postorius:
Apart from these default roles, there are two others relevant in Postorius:
There are a number of decorators to protect views from unauthorized users.
Accessing the Mailman API
Postorius uses mailmanclient to connect to Mailman’s REST API. In order to directly use the client, cd to the example_project folder and execute
python mmclient
. This will open a python shell (IPython, if that’s available) and provide you with a client object connected to your local Mailman API server (it uses the credentials from your
A quick example:
$ python mmclient >>> client <Client (user:pwd) http://localhost:8001/3.1/> >>> print(client.system['mailman_version']) GNU Mailman 3.0.0b2+ (Here Again) >>> mailman_dev = client.get_list('') >>> print(mailman_dev.settings) {u'description': u'Mailman development', u'default_nonmember_action': u'hold', ...}
For detailed information how to use mailmanclient, check out its documentation.
