Building an RC

The Release Candidate artifacts we vote upon should be the exact ones we vote against, without any modification than renaming – i.e. the contents of the files must be the same between voted release canidate and final release. Because of this the version in the built artifacts that will become the official Apache releases must not include the rcN suffix.

• Set environment variables 

  # Set Version export VERSION=1.10.2rc3 # Set AIRFLOW_REPO_ROOT to the path of your git repo export AIRFLOW_REPO_ROOT=$(pwd) # Example after cloning git clone https://github.com/apache/airflow.git airflow cd airflow export AIRFLOW_REPO_ROOT=$(pwd)

  
  

• set your version to 1.10.2 in airflow/version.py (without the RC tag)
• Commit the version change.

• Tag your release

  git tag ${VERSION}

  
  

• Clean the checkout: the sdist step below will

  git clean -fxd

  
  

• Tarball the repo


  git archive --format=tar.gz ${VERSION} --prefix=apache-airflow-${VERSION}/ -o apache-airflow-${VERSION}-source.tar.gz

  
  

• Generate sdist
  NOTE: Make sure your checkout is clean at this stage - any untracked or changed files will otherwise be included in the file produced.

  python setup.py compile_assets sdist bdist_wheel

  
  

• Rename the sdist

  mv dist/apache-airflow-${VERSION%rc?}.tar.gz apache-airflow-${VERSION}-bin.tar.gz mv dist/apache_airflow-${VERSION%rc?}-py2.py3-none-any.whl apache_airflow-${VERSION}-py2.py3-none-any.whl

  
  

• Generate SHA512/ASC (If you have not generated a key yet, generate it by following instructions on http://www.apache.org/dev/openpgp.html#key-gen-generate-key)

  ${AIRFLOW_REPO_ROOT}/dev/sign.sh apache-airflow-${VERSION}-source.tar.gz ${AIRFLOW_REPO_ROOT}/dev/sign.sh apache-airflow-${VERSION}-bin.tar.gz ${AIRFLOW_REPO_ROOT}/dev/sign.sh apache_airflow-${VERSION}-py2.py3-none-any.whl

  


• Push Tags

  git push --tags

  
  

• Push the artifacts to ASF dev dist repo

  # First clone the repo svn checkout https://dist.apache.org/repos/dist/dev/airflow airflow-dev # Create new folder for the release cd airflow-dev svn mkdir ${VERSION} # Move the artifacts to svn folder & commit mv ${AIRFLOW_REPO_ROOT}/apache{-,_}airflow-${VERSION}* airflow-dev/${VERSION}/ cd ${VERSION} svn add * svn commit -m "Add artifacts for Airflow ${VERSION}" # Remove old release # http://www.apache.org/legal/release-policy.html#when-to-archive cd .. export PREVIOUS_VERSION=1.10.1 svn rm ${PREVIOUS_VERSION} svn commit -m "Remove old release: ${PREVIOUS_VERSION}"

  
  

PyPI Snapshots (Optional)

At this point we have the artefact that we vote on, but as a convenience to developers we also want to publish "snapshots" of the RC builds to pypi for installing via pip. To do this we need to

• Edit the airflow/version.py to include the RC suffix.
• python setup.py compile_assets sdist bdist_wheel
• Follow the steps in Releasing Airflow
• Throw away the change - we don't want to commit this: git checkout airflow/version.py

It is important to stress that this snapshot is not intended for users.

Make sure your public key is on id.apache.org and in KEYS

You will need to sign the release artifacts with your pgp key. After you have created a key, make sure you

• Add your GPG pub key to https://dist.apache.org/repos/dist/release/airflow/KEYS , follow the instructions at the top of that file. Upload your GPG public key to https://pgp.mit.edu 
• Add your key fingerprint to https://id.apache.org/ (login with your apache credentials, paste your fingerprint into the pgp fingerprint field and hit save).

# Create PGP Key
gpg --gen-key

# Checkout ASF dist repo
svn checkout https://dist.apache.org/repos/dist/release/airflow
cd airflow


# Add your GPG pub key to KEYS file. Replace "Kaxil Naik" with your name
(gpg --list-sigs "Kaxil Naik" && gpg --armor --export "Kaxil Naik" ) >> KEYS


# Commit the changes
svn commit -m "Add PGP keys of Airflow developers"

See this for more detail on creating keys and what is required for signing releases.

Voting on an RC

• Once the RC is built (both source and binary), put them in the dev SVN repository:
  https://dist.apache.org/repos/dist/dev/airflow/

• Use the dev/airflow-jira script to generate a list of Airflow JIRAs that were closed in the release.

• Send out a vote to the dev@airflow.apache.org mailing list:

  Hey all, I have cut Airflow 1.10.2 RC3. This email is calling a vote on the release, which will last for 72 hours. Consider this my (binding) +1. Airflow 1.10.2 RC3 is available at: https://dist.apache.org/repos/dist/dev/airflow/1.10.2rc3/ *apache-airflow-1.10.2rc3-source.tar.gz* is a source release that comes with INSTALL instructions. *apache-airflow-1.10.2rc3-bin.tar.gz* is the binary Python "sdist" release. Public keys are available at: https://dist.apache.org/repos/dist/release/airflow/KEYS Only votes from PMC members are binding, but members of the community are encouraged to test the release and vote with "(non-binding)". Please note that the version number excludes the `rcX` string, so it's now simply 1.10.2. This will allow us to rename the artifact without modifying the artifact checksums when we actually release. Changes since 1.10.2rc2: *Bugs*: [AIRFLOW-3732] Fix issue when trying to edit connection in RBAC UI [AIRFLOW-2866] Fix missing CSRF token head when using RBAC UI (#3804) ... *Improvements*: [AIRFLOW-3302] Small CSS fixes (#4140) [Airflow-2766] Respect shared datetime across tabs ... *New features*: [AIRFLOW-2874] Enables FAB's theme support (#3719) [AIRFLOW-3336] Add new TriggerRule for 0 upstream failures (#4182) ... *Doc-only Change*: [AIRFLOW-XXX] Fix BashOperator Docstring (#4052) [AIRFLOW-3018] Fix Minor issues in Documentation ... Cheers, <your name>

  
  

• Once the vote has been passed, you will need to send a result vote to dev@airflow.apache.org:

  Hello, Apache Airflow 1.10.2 (based on RC3) has been accepted. 4 “+1” binding votes received: - Kaxil Naik (binding) - Bolke de Bruin (binding) - Ash Berlin-Taylor (binding) - Tao Feng (binding) 4 "+1" non-binding votes received: - Deng Xiaodong (non-binding) - Stefan Seelmann (non-binding) - Joshua Patchus (non-binding) - Felix Uellendall (non-binding) Vote thread: https://lists.apache.org/thread.html/736404ca3d2b2143b296d0910630b9bd0f8b56a0c54e3a05f4c8b5fe@%3Cdev.airflow.apache.org%3E I'll continue with the release process and the release announcement will follow shortly. Cheers, <your name>

  
  

Publishing release

• After both votes pass (see above), you need to migrate the RC artifacts that passed to this repository:
  https://dist.apache.org/repos/dist/release/airflow/
  (The migration should including renaming the files so that they no longer have the RC number in their filenames.)
  
  The best way of doing this is to svn cp  between the two repos (this avoids having to upload the binaries again, and gives a clearer history in the svn commit logs):

  # First clone the repo export RC=1.10.4rc5 export VERSION=${RC/rc?/} svn checkout https://dist.apache.org/repos/dist/release/airflow airflow-release # Create new folder for the release cd airflow-release svn mkdir ${VERSION} cd ${VERSION} # Move the artifacts to svn folder & commit for f in ../../airflow-dev/$RC/*; do svn cp $f ${$(basename $f)/rc?/}; done svn commit -m "Release Airflow ${VERSION} from ${RC}"

  
  

Publishing to PyPi

• Create a ~/.pypirc file:

  $ cat ~/.pypirc [distutils] index-servers = pypi pypitest [pypi] username=your-username password=********* [pypitest] repository=https://test.pypi.org/legacy/ username=your-username password=*********

  (more details here.)

• Set proper permissions for the pypirc file:

  $ chmod 600 ~/.pypirc

  
  

• Confirm that airflow/version.py is set properly.

• Install twine if you do not have it already. 

  pip install twine

  
  

• Build the package:

  python setup.py compile_assets sdist bdist_wheel

  
  

• Verify the artifacts that would be uploaded:

  twine check dist/*

  
  

• Upload the package to PyPi's test environment:

  twine upload -r pypitest dist/*

  
  

• Verify that the test package looks good by downloading it and installing it into a virtual environment. The package download link is available at:
  https://test.pypi.org/project/apache-airflow/#files

• Upload the package to PyPi's production environment:

  twine upload -r pypi dist/*

  
  

• Again, confirm that the package is available here:
  https://pypi.python.org/pypi/apache-airflow
