Apache SkyWalking Python Release Guide

This documentation guides the release manager to release the SkyWalking Python in the Apache Way, and also helps people to check the release for vote.

Prerequisites

  1. Close (if finished, or move to next milestone otherwise) all issues in the current milestone from skywalking-python and skywalking, create a new milestone if needed.
  2. Update CHANGELOG.md and version in pyproject.toml.

Add your GPG public key to Apache SVN

  1. Log in id.apache.org and submit your key fingerprint.

  2. Add your GPG public key into SkyWalking GPG KEYS file, you can do this only if you are a PMC member. You can ask a PMC member for help. DO NOT override the existed KEYS file content, only append your key at the end of the file.

Build and sign the source code package

export VERSION=<the version to release>

git clone --recurse-submodules git@github.com:apache/skywalking-python && cd skywalking-python
git tag -a "v$VERSION" -m "Release Apache SkyWalking-Python $VERSION"
git push --tags

make clean && make release

Upload to Apache SVN

svn co https://dist.apache.org/repos/dist/dev/skywalking/python release/skywalking/python
mkdir -p release/skywalking/python/"$VERSION"
cp skywalking*.tgz release/skywalking/python/"$VERSION"
cp skywalking*.tgz.asc release/skywalking/python/"$VERSION"
cp skywalking-python*.tgz.sha512 release/skywalking/python/"$VERSION"

cd release/skywalking && svn add python/$VERSION && svn commit python -m "Draft Apache SkyWalking-Python release $VERSION"

Make the internal announcement

First, generate a sha512sum for the source code package generated in last step:

sha512sum release/skywalking/python/"$VERSION"/skywalking-python-src-"$VERSION".tgz

Send an announcement email to dev@ mailing list, please check all links before sending the email, the same as below.

All PMC members and committers should check these before voting +1:

  1. Features test.
  2. All artifacts in staging repository are published with .asc, .md5, and sha files.
  3. Source codes and distribution packages (skywalking-python-src-$VERSION.tgz) are in https://dist.apache.org/repos/dist/dev/skywalking/python/$VERSION with .asc, .sha512.
  4. LICENSE and NOTICE are in source codes and distribution package.
  5. Check shasum -c skywalking-python-src-$VERSION.tgz.sha512.
  6. Check gpg --verify skywalking-python-src-$VERSION.tgz.asc skywalking-python-src-$VERSION.tgz.
  7. Build distribution from source code package by following this the build guide.

Vote result should follow these:

  1. PMC vote is +1 binding, all others is +1 no binding.

  2. Within 72 hours, you get at least 3 (+1 binding), and have more +1 than -1. Vote pass.

Publish release

  1. Move source codes tar balls and distributions to https://dist.apache.org/repos/dist/release/skywalking/, you can do this only if you are a PMC member.

    svn mv https://dist.apache.org/repos/dist/dev/skywalking/python/"$VERSION" https://dist.apache.org/repos/dist/release/skywalking/python/"$VERSION"

  2. Refer to the previous PR, update news and links on the website. There are several files need to modify.

Publish PyPI package

After the official ASF release, we publish the packaged wheel to the PyPI index.

  1. Make sure the final upload is correct by using the test PyPI index make upload-test.
  2. Upload the final artifacts by running make upload.

Publish Docker images

After the release on GitHub, a GitHub Action will be triggered to build Docker images based on the latest code.

Important We announce the new release by drafting one on Github release page, following the previous convention.

An automation via GitHub Actions will automatically trigger upon the mentioned release event to build and upload Docker images to DockerHub.

See How-to-release-docker for a detailed description of manual release.

  1. Send ANNOUNCEMENT email to dev@skywalking.apache.org and announce@apache.org, the sender should use his/her Apache email account.
