Installation

Python project

1. Install requirements, if never done before

1.1. For OS X distributions:

1.1.1. Homebrew

      brew install python3

1.1.2 Port

      sudo port install python36

      sudo port select --set python3 python36

      sudo port install py36-pip
      sudo port select --set pip pip36

1.2. For Linux distributions:

sudo apt-get update
sudo apt-get install python3.6

2. Make calibration_client library available in your python environment

2.1. Install it via pip:

# Install dependencies from local wheels files
pip install . --no-index --find-links ./external_dependencies/

# Install dependencies from the pypi
pip install .

Installing it will place two folders under the current Python installation site-packages folder:

• calibration_client with the sources;

• calibration_client-9.0.6.dist-info/ with Wheels configuration files.

To identify your Python site-packages folder run:

python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())"

Usage

To use this project you need to import it:

from calibration_client import CalibrationClient

Development & Testing

When developing, and before commit changes, please validate that:

1. All tests continue passing successfully (to validate that run pytest):

   # Go to the source code directory
   cd calibration_client
   
   # Upgrade package and all its required packages
   pip install . -U --upgrade-strategy eager
   
   # Install test dependencies
   pip install '.[test]' -U --upgrade-strategy eager
   
   # Run all tests using pytest
   pytest
   
   # When running all tests against the standard http application
   OAUTHLIB_INSECURE_TRANSPORT=1 pytest
   
   # Run all tests and get information about coverage for all files inside calibration_client package
   pytest --cov calibration_client --cov-report term-missing

2. Code keeps respecting pycodestyle code conventions (to validate that run pycodestyle):

   pycodestyle .

3. To generate all the wheels files for the dependencies, execute:

   # Generate Wheels to itself and dependencies
   pip wheel --wheel-dir=./external_dependencies .
   pip wheel --wheel-dir=./external_dependencies --find-links=./external_dependencies .

4. Check that you have the desired dependency versions in external_dependencies folder, since no versions are now set in setup.py.

Registering library on https://pypi.org

To register this python library, the following steps are necessary:

# Install twine
python -m pip install --upgrade twine

# Generates source distribution (.tar.gz) and wheel (.whl) files in the dist/ folder
python setup.py sdist
python setup.py bdist_wheel

# Upload new version .egg and .whl files
twine upload dist/*

# In case a test is necessary, it is possible to test it against test.pypi.org
twine upload --repository-url https://test.pypi.org/legacy/ dist/* --verbose
