A guide for developers who are doing a matplotlib release.
We use travis-ci for continuous integration. When preparing for a release, the final tagged commit should be tested locally before it is uploaded:
python tests.py --processes=8 --process-timeout=300
In addition the following two tests should be run and manually inspected:
python unit/memleak_hawaii3.py pushd examples/tests/ python backend_driver.py popd
We automatically extract GitHub issue, PRs, and authors from GitHub via the API:
python tools/github_stats.py --since-tag $TAG --project 'matplotlib/matplotlib' --links > doc/users/github_stats.rst
Review and commit changes. Some issue/PR titles may not be valid rst (the most common issue is
* which is interpreted as unclosed markup).
Before tagging, make sure that the docs build cleanly
pushd doc python make.py html latex -n 16 popd
After the docs are built, check that all of the links, internal and external, are still
valid. We use
linkchecker for this, which has not been ported to python3 yet. You will
need to create a python2 environment with
requests==2.9.0 and linkchecker
conda create -p /tmp/lnkchk python=2 requests==2.9.0 source activate /tmp/lnkchk pip install linkchecker pushd doc/build/html linkchecker index.html --check-extern
Address any issues which may arise. The internal links are checked on travis, this should only flag failed external links.
To create the tag, first create an empty commit with a very terse set of the release notes in the commit message
git commit --allow-empty
and then create a signed, annotated tag with the same text in the body message
git tag -a -s v2.0.0
which will prompt you for your gpg key password and an annotation. For pre releases it is important to follow PEP 440 so that the build artifacts will sort correctly in pypi. Finally, push the tag to GitHub
git push -t DANGER v2.0.0
Congratulations, the scariest part is done!
To prevent issues with any down-stream builders which download the tarball from GitHub it is important to move all branches away from the commit with the tag :
git commit --allow-empty git push DANGER master
The tarball that is provided by GitHub is produced using git
archive. We use
which uses a format string in
To generate the file that GitHub does use
git archive v2.0.0 -o matplotlib-2.0.0.tar.gz --prefix=matplotlib-2.0.0/
If this is a final release, also create a ‘doc’ branch (this is not done for pre-releases):
git branch v2.0.0-doc git push DANGER v2.0.0-doc
and if this is a major or minor release, also create a bug-fix branch (a micro release will be cut off of this branch):
git branch v2.0.x git push DANGER v2.0.x
Via the GitHub UI (chase down link), turn the newly pushed tag into a release. If this is a pre-release remember to mark it as such.
For final releases also get a DOI from zenodo and edit
with DOI link and commit to the VER-doc branch and push to GitHub
git checkout v2.0.0-doc emacs doc/_templates/citing.html git push DANGER v2.0.0-doc:v2.0.0-doc
We distribute mac, windows, and many linux wheels as well as a source
tarball via pypi. Before uploading anything, contact the various
builders. Mac and manylinux wheels are built on travis . You need to
.travis.yml file and push to master of the build
master branch (for pre-releases the
of the conda-forge feedstock via pull request.
If this is a final release the following downstream packagers should be contacted:
This can be done ahead of collecting all of the binaries and uploading to pypi.
Once you have collected all of the wheels, generate the tarball
git checkout v2.0.0 git clean -xfd python setup.py sdist
and copy all of the wheels into
dist directory. You should use
twine to upload all of the files to pypi
twine upload -s dist/matplotlib*tar.gz twine upload dist/*whl
Congratulations, you have now done the second scariest part!
Additionally, for a final release, upload all of the files to sourceforge.
To build the documentation you must have the tagged version installed, but
build the docs from the
ver-doc branch. An easy way to arrange this is:
pip install matplotlib pip install -r doc-requirements.txt git checkout v2.0.0-doc git clean -xfd cd doc python make.py html latex -n 16
which will build both the html and pdf version of the documentation.
The built documentation exists in the matplotlib.github.com repository. Pushing changes to master automatically updates the website.
The documentation is organized by version. At the root of the tree is always the documentation for the latest stable release. Under that, there are directories containing the documentation for older versions. The documentation for current master are built on travis and push to the devdocs repository. These are available at matplotlib.org/devdocs.
Assuming you have this repository checked out in the same directory as matplotlib
cd ../matplotlib.github.com mkdir 2.0.0 rsync -a ../matplotlib/doc/build/html/* 2.0.0 cp ../matplotlib/doc/build/latex/Matplotlib.pdf 2.0.0
which will copy the built docs over. If this is a final release, also replace the top-level docs
rsync -a 2.0.0/* ./
You will need to manually edit
versions.html to show the last
3 tagged versions. Now commit and push everything to GitHub
git add * git commit -a -m 'Updating docs for v2.0.0' git push DANGER master
Congratulations you have now done the third scariest part!
It typically takes about 5-10 minutes for GitHub to process the push and update the live web page (remember to clear your browser cache).
The final step is to announce the release to the world. A short version of the release notes along with acknowledgments should be sent to
For final releases announcements should also be sent to the numpy/scipy/jupyter mailing lists and python-announce.
In addition, announcements should be made on social networks (twitter, g+, FB). For major release, NumFOCUS should be contacted for inclusion in their newsletter and maybe to have something posted on their blog.
