gros-server 1.0.0

Grip on Software server framework

GROS Python server framework

This repository contains a framework for setting up a Web application based on Python modules, using CherryPy for routing.

This framework is used for a few servers within the Grip on Software pipeline, namely the deployer and status-dashboard repositories.

Installation and building

The latest version of GROS server framework module and its dependencies can be installed using pip install gros-server.

Another option is to build the module from this repository, which allows using the most recent development code. Some functionality of the server framework is based on the data gathering module and requires a proper installation of that package. It and other dependencies may be installed using make setup. The server framework itself may then be installed with make install, which places the package in your current environment. We recommend using a virtual environment during development.

Use make build in order to generate a wheel package for the framework. The files can then be found in the dist directory (and installed from there using pip install <path>).

The Jenkinsfile in this repository contains steps to build the package and upload it to a PyPi-based repository so that it may be installed from there, when built on a Jenkins CI server.

Development and testing

To run tests, first install the test dependencies with make setup_test which also installs all dependencies for the server framework. Then make coverage provides test results in the output and in XML versions compatible with, e.g., JUnit and SonarQube available in the test-reports/ directory. If you do not need XML outputs, then run make test to just report on test successes and failures or make cover to also have the terminal report on hits and misses in statements and branches.

GitHub Actions is used to run the unit tests and report on coverage on commits and pull requests. This includes quality gate scans tracked by SonarCloud and Coveralls for coverage history.

The Python module conforms to code style and typing standards which can be checked using Pylint with make pylint and mypy with make mypy, after installing the pylint and mypy dependencies using make setup_analysis; typing reports are XML formats compatible with JUnit and SonarQube placed in the mypy-report/ directory. To also receive the HTML report, use make mypy_html instead.

We publish releases to PyPI using make setup_release to install dependencies and make release which performs multiple checks: unit tests, typing, lint and version number consistency. The release files are also published on GitHub and from there are archived on Zenodo. Noteworthy changes to the module are added to the changelog.
