Releasing software

When releasing a new version, the following steps should be taken:

  1. Make sure all automated tests pass.

  2. Make sure the package metadata in setup.py is up-to-date. You can verify the information by re-generating the egg info:

    python setup.py egg_info

    and inspecting src/pysaml2.egg-info/PKG-INFO. You should also make sure that the long description renders as valid reStructuredText. You can do this by using the rst2html.py utility from docutils:

    python setup.py --long-description | rst2html > test.html

    If this will produce warning or errors, PyPI will be unable to render the long description nicely. It will treat it as plain text instead.

  3. Update the version in the VERSION file and report the changes in CHANGELOG.md and commit the changes.:

    git add CHANGELOG.md
git add VERSION
git commit -v -s -m "Release version X.Y.Z"

  4. Create a release branch:

    git branch vX.Y.Z

  5. Create a release tag:

    git tag -a -s vX.Y.Z -m "Version X.Y.Z"

  6. Push these changes to Github:

    git push --follow-tags origin vX.Y.Z
git push --follow-tags origin vX.Y.Z:vX.Y.Z

  7. Create a source and wheel distribution and upload it to PyPI:

    # generate a source and wheel distribution at once
python setup.py sdist bdist_wheel

# generated files are under dist/
ls dist/

# upload release on test.pypi.org
twine upload --repository-url https://test.pypi.org/legacy/ dist/pysaml2-X.Y.Z*

# then, upload release on official pypi.org
twine upload dist/pysaml2-X.Y.Z*

  8. Upload the documentation to PyPI. First you need to generate the html version of the documentation:

    cd docs/
make clean
make html
cd _build/html
zip -r pysaml2-docs.zip *

    Submit the generated pysaml2-docs.zip file.

  9. Send an email to the pysaml2 list announcing this release

Important: Once released to PyPI or any other public download location, a released egg may never be removed, even if it has proven to be a faulty release ("brown bag release"). In such a case it should simply be superseded immediately by a new, improved release.
