Backend source code of tracim v2, using Pyramid Framework.

Installation

Distribution dependencies

on Debian Stretch (9) with sudo:

sudo apt update
sudo apt install git
sudo apt install python3 python3-venv python3-dev python3-pip
sudo apt install redis-server
sudo apt install zlib1g-dev libjpeg-dev
sudo apt install imagemagick libmagickwand-dev ghostscript

Get the source

get source from github:

git clone https://github.com/tracim/tracim_v2.git

go to backend subdirectory:

cd backend

Setup Python Virtualenv

Create a Python virtual environment:

python3 -m venv env

Activate it in your terminal session (all tracim command execution must be executed under this virtual environment):

source env/bin/activate

Upgrade packaging tools:

pip install --upgrade pip setuptools

Install the project in editable mode with its testing requirements :

pip install -e ".[testing]"

If you want to use postgresql, mysql or other databases than the default one: sqlite, you need to install python driver for those databases that are supported by sqlalchemy.

For postgreSQL and mySQL, those are shortcuts to install Tracim with test and specific driver.

For PostgreSQL:

pip install -e ".[testing,postgresql]"

For mySQL:

pip install -e ".[testing,mysql]"

Configure Tracim_backend

Create configuration file for a development environment:

cp development.ini.sample development.ini

Initialize the database using tracimcli tool

tracimcli db init

create wsgidav configuration file for webdav:

cp wsgidav.conf.sample wsgidav.conf

Run Tracim_backend

With Uwsgi

Run all services with uwsgi

# install uwsgi with pip ( unneeded if you already have uwsgi with python3 plugin enabled)
sudo pip3 install uwsgi
# set tracim_conf_file path
export TRACIM_CONF_PATH="$(pwd)/development.ini"
export TRACIM_WEBDAV_CONF_PATH="$(pwd)/wsgidav.conf"
# pyramid webserver
uwsgi -d /tmp/tracim_web.log --http-socket :6543 --wsgi-file wsgi/web.py -H env --pidfile /tmp/tracim_web.pid
# webdav wsgidav server
uwsgi -d /tmp/tracim_webdav.log --http-socket :3030 --wsgi-file wsgi/webdav.py -H env --pidfile /tmp/tracim_webdav.pid

to stop them:

# pyramid webserver
uwsgi --stop /tmp/tracim_web.pid
# webdav wsgidav server
uwsgi --stop /tmp/tracim_webdav.pid

With Waitress (legacy way, usefull for debug)

run tracim_backend web api:

pserve development.ini

run wsgidav server:

tracimcli webdav start

Run Tests and others checks

Run Tests

Before running some functional test related to email, you need a local working MailHog see here : https://github.com/mailhog/MailHog

You can run it this way with docker :

docker pull mailhog/mailhog
docker run -d -p 1025:1025 -p 8025:8025 mailhog/mailhog

Run your project's tests:

pytest

Lints and others checks

Run mypy checks:

mypy --ignore-missing-imports --disallow-untyped-defs tracim

Run pep8 checks:

pep8 tracim

# launch your favorite web-browser
firefox http://localhost:6543/api/v2/doc/
