Summary by CodeRabbit

  • Refactor
    • Release processing now selects the matching maintenance branch when available.
    • Falls back to the main development branch when no matching maintenance branch exists.
    • Stops the release process when branch availability cannot be determined or an invalid release tag is provided.
    • Adds safeguards to prevent stalled or unsuccessful release preparation from continuing.
    • Applies explicit access controls to release workflow operations.

📝 Walkthrough

Walkthrough

The release workflow now validates release tags and queries the GitHub API to select the ${major}.${minor}.x maintenance branch or main. It handles curl failures and unexpected HTTP responses. It also adds bounded execution time and explicit contents permissions.

Changes

Release branch selection

Layer / File(s) Summary
Detect release source branch
.github/workflows/release.yml
The workflow validates the tag format, adds timeout and contents permissions, and queries the maintenance branch with authenticated, retried curl. HTTP 200 selects the maintenance branch, HTTP 404 selects main, and other failures stop the job. The SDK release job receives write permission for its SNAPSHOT version commit.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to b193d

The release workflow now validates release streams, safely passes release tags through the environment, and selects a maintenance branch or main without an identified remaining merge risk.

Copilot couldn't run its full agentic review because it didn't start before the timeout. Make sure your repository has a runner available, or add a copilot-code-review.yml file specifying one with the runs-on attribute. See the docs for more details.

Pull request overview

Updates the release workflow so it selects a maintenance branch for the release stream when it exists, and falls back to main when no maintenance branch is present.

Changes:

  • Derives MAINTENANCE_BRANCH from the release tag (<major>.<minor>.x).
  • Replaces main-branch POM parsing with a remote branch existence check to choose version_branch.

Transient network issues could stall the release workflow indefinitely,
and a curl failure was only distinguishable from an HTTP response via the
status output. Add connect/overall timeouts with a small retry policy,
check curl's exit code explicitly, and cap the job with timeout-minutes.

In @.github/workflows/release.yml:
- Line 62: Update the branch lookup using MAINTENANCE_BRANCH so the derived
branch is safely represented as a single URL path segment, preserving slashes
such as in 5.3/rc.x through proper encoding; alternatively reject invalid
derived names before the API request. Ensure the existing fallback cannot select
the wrong release stream due to an unencoded branch lookup.

Comment thread .github/workflows/release.yml
A tag such as v5.3/rc derived the branch name 5.3/rc.x, whose slash split
the API URL path into a non-existent endpoint; the resulting 404 quietly
selected main. Reject anything that is not a bare major.minor.

Pass the release tag through the environment rather than expanding it
directly into the shell script, so a tag name can never be interpreted as
code.
