# cellxgene release process
_This document defines the release process for cellxgene_
## Overview
The goal of the release process is to publish an installable package
to PyPi, with a matching tagged release on github.
The release process should result in the following side-effects:
- Version number bump, using semantic versioning
- JS assets built & packaged, committed to the repo
- Tagged github release
- Publication to PyPi
## Recipe
Follow these steps to create a release.
1. Preparation:
- python3.6 environment, and a cellxgene clone
- install required tools: `pip install -r requirements-dev.txt`
- Define the release version number, using [semantic versioning](https://semver.org/),
and specifying all three digits (eg, 0.3.0)
- Write the release title and release notes and add to
[release notes document](https://docs.google.com/document/d/1KnHwkYfhyWO5H8BDcMu7y3ogjvq5Yi4OwpmZ8DB6w0Y/edit)
2. Create a release branch, eg, `release-version`
3. In the release branch:
- Run `bumpversion --config-file .bumpversion.cfg [major | minor | patch]`,
where you choose major/minor/patch depending on which part of the version
is being bumped (eg, 0.2.9->0.3 is minor).
- Clean up existing environment using `bin/clean`
- Build the JS asserts using `bin/build-client`
4. Commit and push the new branch
5. Create a PR for the release.
- [optional] As needed, conduct PR review.
6. Merge to master
7. Create Github release using the version number and release notes
([instructions](https://help.github.com/articles/creating-releases/)).
- Draft new release
- Type version name matching release version number from (1)
- Select `master` as release branch (ensure you merged the release PR)
- Type title `Release {version num}`
- [optional] Check pre-release if this release is not ready for production
- Publish Release
8. Publish to pypi by performing the following steps (assumes you have `setuptools`
and `twine` installed, that you have registered for pypi, and that you have
write access to the cellxgene pypi package):
- Build the distribution by calling `python setup.py sdist`
inside the top-level directory
- [optional] Upload the package to test pypi
`twine upload --repository-url https://test.pypi.org/legacy/ dist/*`
- [optional] Test the test installation in a fresh virtual environment using
`pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple cellxgene`
- Upload the package to real pypi using `twine upload dist/*`
- [optional] Test the installation in a fresh virtual environment using
`pip install cellxgene`
The optional steps are for testing purposes, and are recommended
for publishing any major releases, and any releases that significantly
change the packaging (e.g. new bundled files, new dependencies, etc.)
