Note that this document describes a new Apache Bloodhound project that is intending to replace the Trac-based version. If you are interested in that version, the appropriate code is available from here.
The new version of Apache Bloodhound is in the bloodhound-core git repository which is mirrored on GitHub here.
If you have not already got the code, you can clone the repo with the following command:
git clone https://github.com/apache/bloodhound-core.git
which will put the code in the bloodhound-core
directory.
This version of Apache Bloodhound requires Python, Poetry and Django.
The versions of Python that can be used are currently 3.6, 3.7, 3.8 and 3.9.
Where convenient is it sensible to go for the newest release of Python that you can.
Modern Linux and BSD distributions will have new enough Python 3 packages in their repos and are often already installed if it is not a minimal installation. For these cases it will usually be sensible to take advantage of this.
If this is not the case, you can look for advice from:
- The Hitchhiker's Guide to Python for their installation guides on Mac OS X, Windows and Linux.
- The official Python documentation on Setup and Usage which includes information for installing on more Unix platforms, Windows and Mac.
The project now uses Poetry for python environment management and looking after further dependencies.
If you are installing on linux, it is possible that poetry is installable from the repositories for your distro. For example, on recent Fedora releases, the following should work:
sudo dnf install poetry
For anywhere else you can consider following the instructions from the Poetry documentation.
Once installed, optionally you can pre-configure poetry to make it use a
.venv
directory at the root of poetry projects. This can be helpful as it
makes this easier to find and removal of your copy of the git repo will also
clean up these files. If this seems useful:
poetry config virtualenvs.in-project true
As Poetry creates and manages python virtual environments (virtualenv) for you,
it is useful to be aware of how they are used. For convenience, throughout this
document, any command that requires the virtualenv to be 'active' will be
provided with poetry run
before the command. While this may get old, it is
effectively robust as it should work without having to remind you all the time
to be sure the virtualenv is activated.
For a little more completeness, the following lists the options along with example sessions, each including a command to demonstrate exiting the virtualenv if applicable:
- prefix commands that require the virtualenv with
poetry run
:poetry run python --version poetry run django-admin help
- start the
poetry shell
:poetry shell python --version django-admin help exit
- activate the virtualenv manually (example for bash and assumes the
suggested
virtualenvs.in-project
option was set):source .venv/bin/activate python --version django-admin help deactivate
It should now be possible to use poetry to install the rest of the project dependencies.
From the root of the project folder (probably bloodhound-core
if the above
instructions have been followed) run:
poetry install
The basic setup steps to get running are:
poetry run python manage.py makemigrations trackers
poetry run python manage.py migrate
The above will do the basic database setup.
Note that currently models are in flux and, for the moment, no support should be expected for migrations as models change. This will change when basic models gain stability.
For certain operations it will be useful to have accounts and superusers to
work with. There are a few ways to add a superuser. For interactive use, the
createsuperuser
action is usually straightforward enough:
poetry run python manage.py createsuperuser --email admin@example.com --username admin
Entering the password twice on prompting is currently required. If the options
for --username
and --email
are skipped, the command will request these
details first.
poetry run python manage.py runserver
Amongst the initial output of that command will be something like:
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
Currently, there is not much to see at the specified location. More work has been done on the core API. The following views may be of interest as you explore:
These paths are subject to change.
Unit tests are currently being written with the standard unittest framework. This may be replaced with pytest.
Unit tests are run with the following command:
poetry run python manage.py test
The Selenium tests currently require that Firefox is installed and geckodriver is also on the path. If you do not already have geckodriver, the following shows one method to get it for linux:
PLATFORM_EXT="linux64.tar.gz"
BIN_LOCATION="$HOME/.local/bin"
TMP_DIR=/tmp/geckodriver_download
mkdir -p "$BIN_LOCATION" "$TMP_DIR"
LATEST=$(wget -O - https://github.com/mozilla/geckodriver/releases/latest 2>&1 | awk 'match($0, /geckodriver-(v.*)-'"$PLATFORM_EXT"'/, a) {print a[1]; exit}')
wget -N -P "$TMP_DIR" "https://github.com/mozilla/geckodriver/releases/download/$LATEST/geckodriver-$LATEST-$PLATFORM_EXT"
tar -x geckodriver -zf "$TMP_DIR/geckodriver-$LATEST-$PLATFORM_EXT" -O > "$BIN_LOCATION"/geckodriver
chmod +x "$BIN_LOCATION"/geckodriver
If $BIN_LOCATION
is on the system path, and the development server is
running, it should be possible to run the integration tests.
poetry run python functional_tests.py
There are currently not many tests - those that are there are in place to test the setup above and assume that there will be useful tests in due course.
Fixtures for tests when required can be generated with:
poetry run python manage.py dumpdata trackers --format=yaml --indent=2 > trackers/fixtures/[fixture-name].yaml
