| <h1 id="verify-a-release"><a class="header" href="#verify-a-release">Verify a release</a></h1> |
| <p>When a release candidate is announced on <code>dev@iceberg.apache.org</code>, anyone (committer or not) can help by verifying the artifacts. Verification is required from at least three Apache Iceberg PMC members for the vote to pass.</p> |
| <p>The repository ships a script that performs the full verification end-to-end: <code>dev/release/verify_rc.sh</code>.</p> |
| <h2 id="what-an-rc-announcement-contains"><a class="header" href="#what-an-rc-announcement-contains">What an RC announcement contains</a></h2> |
| <p>A <code>[VOTE] iceberg-go X.Y.Z RC<N></code> thread on <code>dev@iceberg.apache.org</code> will reference:</p> |
| <ul> |
| <li>A signed source tarball under <code>https://dist.apache.org/repos/dist/dev/iceberg/apache-iceberg-go-${VERSION}-rc${RC}/</code> (<code>.tar.gz</code>, <code>.tar.gz.asc</code>, <code>.tar.gz.sha512</code>)</li> |
| <li>The Apache Iceberg <code>KEYS</code> file at <code>https://downloads.apache.org/iceberg/KEYS</code></li> |
| <li>A GitHub compare URL between the previous release tag and the new RC tag</li> |
| </ul> |
| <h2 id="prerequisites"><a class="header" href="#prerequisites">Prerequisites</a></h2> |
| <p>The script requires:</p> |
| <ul> |
| <li><code>curl</code></li> |
| <li><code>gpg</code></li> |
| <li><code>shasum</code> or <code>sha512sum</code></li> |
| <li><code>tar</code></li> |
| </ul> |
| <p>You do not need Go installed - if Go is not on the system, the latest Go is downloaded automatically and used only for verification.</p> |
| <h2 id="import-the-apache-iceberg-keys"><a class="header" href="#import-the-apache-iceberg-keys">Import the Apache Iceberg KEYS</a></h2> |
| <pre><code class="language-sh">curl https://downloads.apache.org/iceberg/KEYS -o KEYS |
| gpg --import KEYS |
| </code></pre> |
| <h2 id="run-the-verification-script"><a class="header" href="#run-the-verification-script">Run the verification script</a></h2> |
| <p>The script takes the version and RC number as positional arguments:</p> |
| <pre><code class="language-sh">dev/release/verify_rc.sh ${VERSION} ${RC} |
| </code></pre> |
| <p>For example, to verify <code>0.6.0</code> RC1:</p> |
| <pre><code class="language-sh">dev/release/verify_rc.sh 0.6.0 1 |
| </code></pre> |
| <p>If the verification succeeds, the script prints:</p> |
| <pre><code>RC looks good! |
| </code></pre> |
| <h2 id="optional-environment-variables"><a class="header" href="#optional-environment-variables">Optional environment variables</a></h2> |
| <p><code>verify_rc.sh</code> honors these environment variables (all optional):</p> |
| <div class="table-wrapper"><table><thead><tr><th>Variable</th><th>Default</th><th>Effect</th></tr></thead><tbody> |
| <tr><td><code>VERIFY_DEFAULT</code></td><td><code>1</code></td><td>Master switch propagated to <code>VERIFY_DOWNLOAD</code> and <code>VERIFY_SIGN</code> if they are unset.</td></tr> |
| <tr><td><code>VERIFY_DOWNLOAD</code></td><td><code>${VERIFY_DEFAULT}</code></td><td>Re-download artifacts when <code>1</code>; reuse the local copy when <code>0</code>.</td></tr> |
| <tr><td><code>VERIFY_SIGN</code></td><td><code>${VERIFY_DEFAULT}</code></td><td>Re-run signature and checksum verification when <code>1</code>.</td></tr> |
| <tr><td><code>VERIFY_FORCE_USE_GO_BINARY</code></td><td><code>0</code></td><td>When <code>1</code>, ignore any system Go and use the script's auto-downloaded Go.</td></tr> |
| <tr><td><code>GITHUB_TOKEN</code></td><td>unset</td><td>Optional - supplies authenticated requests when fetching the latest Go release, avoiding rate limits.</td></tr> |
| </tbody></table> |
| </div> |
| <h2 id="manual-verification-fallback"><a class="header" href="#manual-verification-fallback">Manual verification fallback</a></h2> |
| <p>If you would rather verify by hand, the underlying steps are:</p> |
| <pre><code class="language-sh"># Download the artifacts |
| curl -O https://dist.apache.org/repos/dist/dev/iceberg/apache-iceberg-go-${VERSION}-rc${RC}/apache-iceberg-go-${VERSION}.tar.gz |
| curl -O https://dist.apache.org/repos/dist/dev/iceberg/apache-iceberg-go-${VERSION}-rc${RC}/apache-iceberg-go-${VERSION}.tar.gz.asc |
| curl -O https://dist.apache.org/repos/dist/dev/iceberg/apache-iceberg-go-${VERSION}-rc${RC}/apache-iceberg-go-${VERSION}.tar.gz.sha512 |
| |
| # Verify the signature |
| gpg --verify apache-iceberg-go-${VERSION}.tar.gz.asc apache-iceberg-go-${VERSION}.tar.gz |
| |
| # Verify the checksum (or sha512sum -c on systems without shasum) |
| shasum -a 512 --check apache-iceberg-go-${VERSION}.tar.gz.sha512 |
| |
| # Inspect the contents |
| tar xf apache-iceberg-go-${VERSION}.tar.gz |
| </code></pre> |
| <p>You should reply to the <code>[VOTE]</code> thread with <code>+1</code>, <code>+0</code>, or <code>-1</code> and a one-line description of what you verified (for example, "verified signatures, checksums, and <code>verify_rc.sh</code> passed on macOS arm64 with system Go 1.25.5").</p> |
