This is the release documentation for releasing a new version of screed. This document is meant for screed release managers. Michael R. Crusoe and C. Titus Brown have released screed in the past. Jake Fenton is the first to release screed using this checklist.
Start with a clean checkout:
cd `mktemp -d`
git clone git@github.com:ged-lab/screed.git
cd screed
Install/update versioneer:
pip install versioneer
versioneer-installer
If there is a new version of versioneer:
git diff
./setup.py versioneer
git commit -p -m "new version of versioneer.py"
# or abandon the changes
git checkout -- versioneer.py screed/_version.py screed/__init.py \
MANIFEST.in
Review the git logs since the previous release and that ChangeLog reflects the major changes:
git log --minimal --patch \
`git describe --tags --always --abbrev=0`..HEAD
Review the issue list for any existing bugs that won’t be fixed in the release and ensure they’re documented in doc/known-issues.txt
Verify that the build is clean: http://ci.ged.msu.edu/job/screed/
Set the new version number and release candidate:
new_version=1.1
rc=rc3
Tag the release candidate with the new version prefixed by the letter ‘v’:
git tag v${new_version}-${rc}
git push --tags git@github.com:ged-lab/screed.git
Test the release candidate:
cd ..
virtualenv testenv1
virtualenv testenv2
virtualenv testenv3
virtualenv testenv4
# first we test the tag
cd testenv1
source bin/activate
pip install nose
git clone --depth 1 --branch v${new_version}-${rc} \
https://github.com/ged-lab/screed.git
cd screed
make install
nosetests screed --attr '!known_failing'
make test
python -c 'import screed; print screed.__version__' # double-check
version number
# Test via pip
cd ../../testenv2
source bin/activate
pip install nose
pip install -e
git+https://github.com/ged-lab/screed.git@v${new_version}-${rc}#egg=screed
cd src/screed
make dist
make install
nosetests screed --attr '!known_failing'
python -c 'import screed; print screed.__version__'
cp dist/screed*tar.gz ../../../testenv3
# test if the dist made in testenv2 is complete enough to build another
# functional dist
cd ../../../testenv3
source bin/activate
pip install nose
pip install screed*tar.gz
nosetests screed --attr '!known_failing'
python -c 'import screed; print screed.__version__'
tar xzf screed*tar.gz
cd screed*
make dist
make test
Publish the new release on the testing PyPI server. You will need to change your PyPI credentials as documented here: https://wiki.python.org/moin/TestPyPI. You may need to re-register:
python setup.py register --repository test
Now, upload the new release:
python setup.py sdist upload -r test
Test the PyPI release in a new virtualenv:
cd ../../testenv4
source bin/activate
pip install -U setuptools
pip install nose
pip install -i https://testpypi.python.org/pypi --pre --no-clean screed
nosetests screed --attr '!known_failing'
python -c 'import screed; print screed.__version__'
cd build/screed
./setup.py nosetests --attr '!known_failing'
Do any final testing (acceptance tests, etc.) Note that the acceptance tests for screed are to run the khmer automated tests with the new version of screed installed and then to run the khmer acceptance tests.
Make sure any release notes are merged into doc/release-notes/. Release notes should be written in the .md format to allow for GitHub rich text diffs and in-browser editing. The convert-release-notes maketarget can be used to generate .rst files from the .md notes.
When you have a thoroughly tested release candidate, cut a release like so:
Create the final tag and publish the new release on PyPI (requires an authorized account)
cd ../../../screed
git tag v${new_version}
python setup.py register sdist upload
Delete the release candidate tag and push the tag updates to GitHub:
git tag -d v${new_version}-${rc}
git push git@github.com:ged-lab/screed.git
git push --tags git@github.com:ged-lab/screed.git
Add the release on GitHub, using the tag you just pushed. Name it “Version X.Y.Z” and copy/paste in the release notes.
Update the Read the Docs to point to the new version. Visit https://readthedocs.org/builds/screed/ and ‘Build Version: master’ to pick up the new tag. Once that build has finished check the “Activate” box next to the new version at https://readthedocs.org/dashboard/screed/versions/ under “Choose Active Versions”. Finally change the default version at https://readthedocs.org/dashboard/screed/advanced/ to the new version.
Delete any RC tags created:
git tag -d ${new_version}-${rc}
git push origin :refs/tags/${new_version}-${rc}
Tweet about the new release
Send email including the release notes to khmer@lists.idyll.org and khmer-announce@lists.idyll.org
This is the procedure for cutting a new release of screed. It has been adapted from the release documentation for the khmer project, found at http://khmer.readthedocs.org/en/v1.1/release.html.
