This document mainly introduces how the release manager releases a new version 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:

  • iceberg_version: the version of Iceberg to be released, like 0.2.0.
  • release_version: the version of release candidate, like 0.2.0-rc.1.
  • rc_version: the minor version for voting round, like rc.1.

Preparation

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 a tracking issue about the next release

Start a tracking issue on GitHub for the upcoming release to track all tasks that need to be completed.

Title:

Tracking issues of Iceberg Rust ${iceberg_version} Release

Content:

This issue is used to track tasks of the iceberg rust ${iceberg_version} release.

## Tasks

### Blockers

> Blockers are the tasks that must be completed before the release.

### Build Release

#### GitHub Side

- [ ] Bump version in project
- [ ] Update docs
- [ ] Generate dependencies list
- [ ] Push release candidate tag to GitHub

#### ASF Side

- [ ] Create an ASF Release
- [ ] Upload artifacts to the SVN dist repo

### Voting

- [ ] Start VOTE at iceberg community

### Official Release

- [ ] Push the release git tag
- [ ] Publish artifacts to SVN RELEASE branch
- [ ] Change Iceberg Rust Website download link
- [ ] Send the announcement

For details of each step, please refer to: https://rust.iceberg.apache.org/release

GitHub Side

Bump version in project

Bump all components' version in the project to the new iceberg 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

Update docs

Generate dependencies list

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

Running python3 ./scripts/dependencies.py generate to update the dependencies 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 "v0.2.0-rc.1", please correctly check out the corresponding commit instead of directly tagging on the main branch.
  • Push tags to GitHub: git push --tags.

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.

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 v0.2.0-rc.1, tag is created in the previous step)
  • Use the release script to create a new release: ICEBERG_VERSION=<iceberg_version> ICEBERG_VERSION_RC=<rc_version> ./scripts/release.sh(e.g. ICEBERG_VERSION=0.2.0 ICEBERG_VERSION_RC=rc.1 ./scripts/release.sh)
    • This script will do the following things:
      • Create a new branch named by release-${release_version} from the tag
      • Generate the release candidate artifacts under dist, including:
        • apache-iceberg-rust-${release_version}-src.tar.gz
        • apache-iceberg-rust-${release_version}-src.tar.gz.asc
        • apache-iceberg-rust-${release_version}-src.tar.gz.sha512
      • Check the header of the source code. This step needs docker to run.
  • Push the newly created branch to GitHub

This script will create a new release under dist.

For example:

> tree dist
dist
├── apache-iceberg-rust-0.2.0-src.tar.gz
├── apache-iceberg-rust-0.2.0-src.tar.gz.asc
└── apache-iceberg-rust-0.2.0-src.tar.gz.sha512

Upload artifacts to the SVN dist repo

SVN is required for this step.

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

First, checkout Iceberg 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/iceberg/ /tmp/iceberg-dist-dev

Then, upload the artifacts:

The ${release_version} here should be like 0.2.0-rc.1

# create a directory named by version
mkdir /tmp/iceberg-dist-dev/${release_version}
# copy source code and signature package to the versioned directory
cp ${repo_dir}/dist/* /tmp/iceberg-dist-dev/iceberg-rust-${release_version}/
# change dir to the svn folder
cd /tmp/iceberg-dist-dev/
# 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/iceberg/iceberg-rust/ to make sure the artifacts are uploaded correctly.

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.
