This document guides a contributor through creating a release of JupyterLab.
The recommended way to make a release is to use jupyter_releaser
.
The full process is documented in https://jupyter-releaser.readthedocs.io/en/latest/get_started/making_first_release.html#making-your-first-release. There is a recording of the full workflow on YouTube.
Here is a quick summary of the different steps.
The first step is to generate a new changelog entry for the upcoming release.
We use the "Draft Changelog" workflow as documented here: https://jupyter-releaser.readthedocs.io/en/latest/get_started/making_first_release.html#draft-changelog
The workflow takes a couple of input parameters. Here is an overview with example values:
Input | Description | Example Value |
---|---|---|
Target | The owner/repo GitHub target | jupyterlab/jupyterlab |
Branch | The branch to target | master |
Version Spec | New Version Spec | next |
Since | Use PRs since activity since this date or git reference | v4.0.0a15 |
The version spec follows the specification documented below in the Bump Version section.
We can use next
when making a patch
release or a build
pre-release.
Click on "Run workflow", then wait for:
- the PR to be created on the repo. Example: jupyterlab#11422
- Tests to pass
- Merge the changelog PR
Before running the "Full Release" workflow, make sure you have been added to:
- the
jupyterlab
project on PyPI: https://pypi.org/project/jupyterlab/ - the
@jupyterlab
organization on npm: https://www.npmjs.com/settings/jupyterlab/packages
Then create the PyPI and npm tokens. Check out the links in the Jupyter Releaser Setup Documentation for more information.
On the jupyter_releaser
fork, select the "Full Release" workflow.
Fill in the information as mentioned in the body of the changelog PR, for example:
Input | Value |
---|---|
Target | jupyterlab/jupyterlab |
Branch | master |
Version Spec | next |
Since | v4.0.0a15 |
The "Full Release" workflow:
- builds and uploads the
jupyterlab
Python package to PyPI - builds the
@jupyterlab/*
packages and uploads them tonpm
- creates a new GitHub Release with the new changelog entry as release notes
- creates a PR to forward port the new changelog entry to the main branch (when releasing from a branch that is not the default)
Then follow the Post release candidate checklist if applicable.
Review CONTRIBUTING.md
. Make sure all the tools needed to generate the
built JavaScript files are properly installed.
We publish the npm packages, a Python source package, and a Python universal binary wheel. We also publish a conda package on conda-forge (see below). See the Python docs on package uploading for twine setup instructions and for why twine is the recommended method.
For convenience, here is a script for getting a completely clean repo. This
makes sure that we don't have any extra tags or commits in our repo (especially
since we will push our tags later in the process), and that we are on the correct branch. The script creates a conda env, pulls down a git checkout with the
appropriate branch, and installs JupyterLab with pip install -e .
.
Make sure you are running an sh-compatible shell, and it is set up to be able to do conda activate
. Then do:
source scripts/release_prep.sh <branch_name>
The next step is to bump the appropriate version numbers. We use bump2version to manage the Python version, and we keep the JS versions and tags in sync with the release cycle.
Here is an example of how version numbers progress through a release process. Choose and run an appropriate command to bump version numbers for this release.
Command | Python Version Change | NPM Version change |
---|---|---|
jlpm bumpversion major |
x.y.z-> (x+1).0.0.a0 | All a.b.c -> a.(b+10).0-alpha.0 |
jlpm bumpversion minor |
x.y.z-> x.(y+1).0.a0 | All a.b.c -> a.(b+1).0-alpha.0 |
jlpm bumpversion build |
x.y.z.a0-> x.y.z.a1 | All a.b.c-alpha.0 -> a.b.c-alpha.1 |
jlpm bumpversion release |
x.y.z.a1-> x.y.z.b0 | All a.b.c-alpha.1 -> a.b.c-beta.0 |
jlpm bumpversion release |
x.y.z.b1-> x.y.z.rc0 | All a.b.c-beta.1 -> a.b.c-rc.0 |
jlpm bumpversion release |
x.y.z.rc0-> x.y.z | All a.b.c-rc0 -> a.b.c |
jlpm bumpversion patch |
x.y.z -> x.y.(z+1) | Changed a.b.c -> a.b.(c+1) |
Note: For a major release, we bump the JS packages by 10 versions so that we are not competing amongst the minor releases for version numbers. We are essentially sub-dividing semver to allow us to bump minor versions of the JS packages as many times as we need to for minor releases of the top level JupyterLab application.
Other note: It's ok if yarn-deduplicate
exits with a non zero code. This is
expected!
In a major Python release, we can have one or more JavaScript packages also have a major bump. During the prerelease stage of a major release, if there is a backwards-incompatible change to a JS package, bump the major version number for that JS package:
jlpm bump:js:major [...packages]
NOTE You should rebase before running jlpm bump:js:major
to avoid a cascade of merge conflicts.
Results:
- Python package is not affected.
- JS dependencies are also bumped a major version.
- Packages that have already had a major bump in this prerelease cycle are not affected.
- All affected packages changed to match the current release type of the Python package (
alpha
,beta
, orrc
).
Now publish the JS packages
npm run publish:js
If there is a network error during JS publish, run npm run publish:js --skip-build
to resume publish without requiring another clean and build phase of the JS packages.
Note that the use of npm
instead of jlpm
is significant on Windows.
Next, prepare the python release by running:
npm run prepare:python-release
This will update the Python package to use the new JS packages and create the Python release assets. Note: sometimes the npm registry is slow to update with the new packages, so this script tries to fetch the packages until they are available.
At this point, run the ./scripts/release_test.sh
to test the wheel in
a fresh conda environment with and without extensions installed. Open and run
the Outputs notebook and verify everything runs properly. Also add a cell with the following code and make sure the widget renders:
from ipywidgets import IntSlider
IntSlider()
Follow instructions printed at the end of the publish step above:
twine upload dist/*
git push origin --tags <BRANCH>
These lines:
- upload to pypi with twine
- double-check what branch you are on, then push changes to the correct upstream branch with the
--tags
option.
- Modify and run
python scripts/milestone_check.py
to check the issues assigned to this milestone - Write release highlights, starting with:
loghub jupyterlab/jupyterlab -m XXX -t $GITHUB_TOKEN --template scripts/release_template.txt
- Test the release candidate in a clean environment
- Make sure the CI builds pass
- The build will fail if we publish a new package because by default it is
private. Use
npm access public @jupyterlab/<name>
to make it public. - The build will fail if we forget to include
style/
in thefiles:
of a package (it will fail on thejupyter lab build
command because webpack cannot find the referenced styles to import.
- The build will fail if we publish a new package because by default it is
private. Use
- Update the other repos:
- https://github.com/jupyterlab/extension-cookiecutter-js
- https://github.com/jupyterlab/extension-cookiecutter-ts
- https://github.com/jupyterlab/mimerender-cookiecutter
- https://github.com/jupyterlab/mimerender-cookiecutter-ts
- https://github.com/jupyterlab/theme-cookiecutter
- https://github.com/jupyterlab/jupyter-renderers
- Add a tag to ts cookiecutter with the new JupyterLab version
- Update the extension examples:
- Update the extension tutorial
- At this point, there may have been some more commits merged. Run
python scripts/milestone_check.py
to check the issues assigned to this milestone one more time. Update changelog if necessary.
Now do the actual final release:
- Run
jlpm run bumpversion release
to switch to final release - Push the commit and tags to master
- Run
npm run publish:all
to publish the packages - Create a branch for the release and push to GitHub
- Update the API docs
- Merge the PRs on the other repos and set the default branch of the xckd repo
- Publish to conda-forge.
After a few days (to allow for possible patch releases), set up development for the next release:
- Run
jlpm run bumpversion minor
to bump to alpha for the next alpha release - Put the commit and tags to master
- Run
npm run publish:all
to publish the packages - Release the other repos as appropriate
- Update version for binder
- Clone the repo if you don't have it
git clone git@github.com:jupyterlab/jupyterlab_apod.git
If the updates are simple, it may be enough to check out a new branch based on the current base branch, then rebase from the root commit, editing the root commit and other commits that involve installing packages to update to the new versions:
git checkout -b BRANCH # whatever the new version is, e.g., 1.0
git rebase -i --root
"Edit" the commits that involve installing packages, so you can update the
package.json
. Amend the last commit to bump the version number in package.json
in preparation for publishing to npm. Then skip down to the step below about
publishing the extension tutorial. If the edits are more substantial than just
updating package versions, then do the next steps instead.
- Create a new empty branch in the extension repo.
git checkout --orphan name-of-branch
git rm -rf .
git clean -dfx
cookiecutter -o initial path-to-local-extension-cookiecutter-ts
# Fill in the values from the previous branch package.json initial commit
cp -r initial/jupyterlab_apod .
rm -rf initial
- Create a new PR in JupyterLab.
- Run through the tutorial in the PR, making commits and updating the tutorial as appropriate.
- For the publish section of the readme, use the
README
file from the previous branch, as well as thepackage.json
fields up tolicense
. Bump the version number in preparation for publishing to npm.
-
Tag commits in the branch with the appropriate
branch-step
tag. If you are at the final commit, you can tag all commits with the below, replacingBRANCH
with the branch name (e.g.,1.0-01-show-a-panel
) ```bash git tag BRANCH-01-show-a-panel HEAD4 git tag BRANCH-02-show-an-image HEAD3 git tag BRANCH-03-style-and-attribute HEAD2 git tag BRANCH-04-refactor-and-refresh HEAD1 git tag BRANCH-05-restore-panel-state HEAD -
Push the branch with the new tags
git push origin BRANCH --tags
Set the branch as the default branch (see
github.com/jupyterlab/jupyterlab_apod/settings/branches
). -
If there were changes to the example in the documentation, submit a PR to JupyterLab
-
Publish the new
jupyterlab_apod
python package. Make sure to update the version number in the last commit of the branch.twine upload dist/*
If you make a mistake and need to start over, clear the tags using the
following pattern (replacing BRANCH
with the branch name):
git tag | grep BRANCH | xargs git tag -d
- If no requirements have changed, wait for the conda-forge autotick-bot.
- Otherwise:
- Get the sha256 hash for conda-forge release:
shasum -a 256 dist/*.tar.gz
- Fork https://github.com/conda-forge/jupyterlab-feedstock
- Create a PR with the version bump
- Update
recipe/meta.yaml
with the new version and md5 and reset the build number to 0.
Run source scripts/docs_push.sh
to update the gh-pages
branch that backs http://jupyterlab.github.io/jupyterlab/.
- Backport the change to the previous release branch
- Run the following script, where the package is in
/packages/package-folder-name
(note that multiple packages can be given, or no packages for a Python-only patch release):
jlpm run patch:release package-folder-name
- Push the resulting commit and tag
Each time we release JupyterLab, we should update the version of JupyterLab used in binder and repo2docker. Here is an example PR that updates the relevant files:
https://github.com/jupyter/repo2docker/pull/169/files
This needs to be done in both the conda and pip buildpacks in both the frozen and non-frozen version of the files.
