Create a release

This document mainly introduces how the release manager releases a new version of Apache OpenDAL™ in accordance with the Apache requirements.

Introduction​

Source Release is the key point which Apache values, and is also necessary for an ASF release.

Please remember that publishing software has legal consequences.

This guide complements the foundation-wide policies and guides:

Some Terminology of release​

In the context of our release, we use several terms to describe different stages of the release process.

Here's an explanation of these terms:

  • opendal_version: the version of OpenDAL to be released, like 0.36.0.
  • release_version: the version of release candidate, like 0.36.0-rc.1.
  • rc_version: the minor version for voting round, like rc.1.
  • maven_artifact_number: the number for Maven staging artifacts, like 1010. The number can be found by searching "opendal" on https://repository.apache.org/#stagingRepositories. And the Maven staging artifacts will be created automatically when we push a git tag to GitHub for now.

Preparation​

caution

This section is the requirements for individuals who are new to the role of release manager.

Refer to Setup GPG Key to make sure the GPG key has been set up.

Start discussion about the next release​

Start a discussion about the next release via sending email to: dev@opendal.apache.org:

For details of each step, please refer to: https://opendal.apache.org/community/committers/release

GitHub Side​

Bump version in project​

Bump all components' version in the project to the new opendal version. Please note that this version is the exact version of the release, not the release candidate version.

  • rust core: bump version in Cargo.toml
  • cpp binding: bump version in bindings/cpp/CMakeLists.txt
  • haskell binding: bump version and update the tag field of source-repository this in bindings/haskell/opendal.cabal
  • java binding: bump version in bindings/java/pom.xml
  • node.js binding: bump version in bindings/nodejs/package.json and bindings/nodejs/npm/*/package.json

Update docs​

  • Update CHANGELOG.md, refer to Generate Release Note for more information.
  • Update core/src/docs/upgrade.md if there are breaking changes in core
  • Make sure every released bindings' upgrade.md has been updated.
    • java: bindings/java/upgrade.md
    • node.js: bindings/nodejs/upgrade.md
    • python: bindings/python/upgrade.md

Generate dependencies list​

Download and setup cargo-deny. You can refer to cargo-deny.

Running python3 ./scripts/dependencies.py generate to update the dependency list of every package.

Push release candidate tag​

After bump version PR gets merged, we can create a GitHub release for the release candidate:

  • Create a tag at main branch on the Bump Version / Patch up version commit: git tag -s "v0.36.0-rc.1", please correctly check out the corresponding commit instead of directly tagging on the main branch.
  • Push tags to GitHub: git push --tags.
note

Pushing a Git tag to GitHub repo will trigger a GitHub Actions workflow that creates a staging Maven release on https://repository.apache.org which can be verified on voting.

Check the GitHub action status​

After pushing the tag, we need to check the GitHub action status to make sure the release candidate is created successfully.

In the most cases, it would be great to rerun the failed workflow directly when you find some failures. But if a new code patch is needed to fix the failure, you should create a new release candidate tag, increase the rc number and push it to GitHub.

ASF Side​

If any step in the ASF Release process fails and requires code changes, we will abandon that version and prepare for the next one. Our release page will only display ASF releases instead of GitHub Releases.

Additionally, we should also drop the staging Maven artifacts on https://repository.apache.org.

Create an ASF Release​

After GitHub Release has been created, we can start to create ASF Release.

  • Checkout to released tag. (e.g. git checkout v0.36.0-rc.1, tag is created in the previous step)
  • Use the release script to create a new release: python ./scripts/release.py
    • This script will generate the release candidate artifacts under dist, including:
      • apache-opendal-{package}-{version}-src.tar.gz
      • apache-opendal-{package}-{version}-src.tar.gz.asc
      • apache-opendal-{package}-{version}-src.tar.gz.sha512
  • Push the newly created branch to GitHub

This script will create a new release under dist.

For example:

dist
├── apache-opendal-bindings-c-0.44.2-src.tar.gz
├── apache-opendal-bindings-c-0.44.2-src.tar.gz.asc
├── apache-opendal-bindings-c-0.44.2-src.tar.gz.sha512
...
├── apache-opendal-core-0.45.0-src.tar.gz
├── apache-opendal-core-0.45.0-src.tar.gz.asc
├── apache-opendal-core-0.45.0-src.tar.gz.sha512
├── apache-opendal-integrations-dav-server-0.0.0-src.tar.gz
├── apache-opendal-integrations-dav-server-0.0.0-src.tar.gz.asc
├── apache-opendal-integrations-dav-server-0.0.0-src.tar.gz.sha512
├── apache-opendal-integrations-object_store-0.42.0-src.tar.gz
├── apache-opendal-integrations-object_store-0.42.0-src.tar.gz.asc
└── apache-opendal-integrations-object_store-0.42.0-src.tar.gz.sha512

1 directory, 60 files

Upload artifacts to the SVN dist repo​

info

SVN is required for this step.

The svn repository of the dev branch is: https://dist.apache.org/repos/dist/dev/opendal

First, checkout OpenDAL to local directory:

# As this step will copy all the versions, it will take some time. If the network is broken, please use svn cleanup to delete the lock before re-execute it.
svn co https://dist.apache.org/repos/dist/dev/opendal opendal-dist-dev

Then, upload the artifacts:

The ${release_version} here should be like 0.36.0-rc.1

cd opendal-dist-dev
# create a directory named by version
mkdir ${release_version}
# copy source code and signature package to the versioned directory
cp ${repo_dir}/dist/* ${release_version}/
# check svn status
svn status
# add to svn
svn add ${release_version}
# check svn status
svn status
# commit to SVN remote server
svn commit -m "Prepare for ${release_version}"

Visit https://dist.apache.org/repos/dist/dev/opendal/ to make sure the artifacts are uploaded correctly.

Close the Nexus staging repo​

To verify the Maven staging artifacts in the next step, close the Nexus staging repo as below.

  1. Open https://repository.apache.org/#stagingRepositories with your Apache ID login.
  2. Find the artifact orgapacheopendal-${maven_artifact_number}, click the "Close" button.

The close operation means that the artifacts are ready for voting.

caution

If the vote failed, click "Drop" to drop the staging Maven artifacts.

Rescue​

If you accidentally published wrong or unexpected artifacts, like wrong signature files, wrong sha256 files, please cancel the release for the current release_version, increase th RC counting and re-initiate a release with the new release_version. And remember to delete the wrong artifacts from the SVN dist repo. Additionally, you should also drop the staging Maven artifacts on https://repository.apache.org.

Voting​

OpenDAL requires votes from both the OpenDAL Community.

Vote should send email to: dev@opendal.apache.org:

Title:

python verify.py

Thanks

${name}

Example: https://lists.apache.org/thread/c211gqq2yl15jbxqk4rcnq1bdqltjm5l

The vote should be open for at least 72 hours except the following cases:

  1. Security issues
  2. The wild user effected bug fixes
  3. Any other emergency cases

The Release manager should claim the emergency cases in the vote email if he want to vote it rapidly.

Tips: The 72 hours is the minimum time for voting, so we can ensure that community members from various time zones can participate in the verification process.

After at least 3 +1 binding vote (from OpenDAL Podling PMC member) and no veto, claim the vote result:

Title:

[RESULT][VOTE] Release Apache OpenDAL ${release_version} - Vote Round 1

Content:

Hello, Apache OpenDAL Community,

The vote to release Apache OpenDAL ${release_version} has passed.

The vote PASSED with 3 +1 binding and 1 +1 non-binding votes, no +0 or -1 votes:

Binding votes:

- xxx
- yyy
- zzz

Non-Binding votes:

- aaa

Vote thread: ${vote_thread_url}

Thanks

${name}

It's better to use the real name or the public name which is displayed on the voters' profile page, or Apache ID of the voter, to show who voted in the vote result email, and avoid using nicknames, it will make the vote result hard for others to track the voter. We should make sure the binding votes are from the people who have the right to vote the binding one.

Example: https://lists.apache.org/thread/xk5myl10mztcfotn59oo59s4ckvojds6

Official Release​

Push the release git tag​

# Checkout the tags that passed VOTE
git checkout ${release_version}
# Tag with the opendal version
git tag -s ${opendal_version}
# Push tags to GitHub to trigger releases
git push origin ${opendal_version}

Publish artifacts to SVN RELEASE branch​

svn mv https://dist.apache.org/repos/dist/dev/opendal/${release_version} https://dist.apache.org/repos/dist/release/opendal/${opendal_version} -m "Release ${opendal_version}"

Change the download link in the website to the new release version.

Update the latest release link and add the new release link to the version list.

Take Add 0.39.0 release link to download.md as an example.

Release Maven artifacts​

  1. Open https://repository.apache.org/#stagingRepositories.
  2. Find the artifact orgapacheopendal-${maven_artifact_number}, click the "Release" button.

It will take some time to sync the Maven artifacts to the Maven Central.

caution

If the vote failed, click "Drop" to drop the staging Maven artifacts.

Check the language binding artifacts​

We need to check the language binding artifacts in the language package repo to make sure they are released successfully.

For Java binding, if we cannot find the latest version of artifacts in the repo, we need to check the orgapacheopendal-${maven_artifact_number} artifact status in staging repo.

For non-Java bindings, if we cannot find the latest version of artifacts in the repo, we need to check the GitHub action status.

Create a GitHub Release​

  • Click here to create a new release.
  • Pick the git tag of this release version from the dropdown menu.
  • Make sure the branch target is main.
  • Generate the release note by clicking the Generate release notes button.
  • Add the release note from every component's upgrade.md if there are breaking changes before the content generated by GitHub. Check them carefully.
  • Publish the release.

Send the announcement​

Send the release announcement to dev@opendal.apache.org and CC announce@apache.org.

Tips: Please follow the Committer Email guide to make sure you have already set up the email SMTP. Otherwise, your email cannot be sent to the announcement mailing list.

Instead of adding breaking changes, let's include the new features as "notable changes" in the announcement.
