Walkthrough

This update modifies several GitHub Actions workflow files to replace floating or generic version tags for actions with specific commit SHAs. Actions such as actions/checkout, actions/setup-python, and others are now referenced by their exact commit hashes, ensuring deterministic and reproducible workflow runs. No changes were made to the logic, steps, or control flow of any workflows; only the action references were updated. There are no changes to exported or public code entities, as all modifications are confined to workflow configuration files.

Changes

File(s)	Change Summary
.github/workflows/check-links.yaml	Updated action references from version tags to specific commit SHAs for actions/checkout and gaurav-nelson/github-action-markdown-link-check.
.github/workflows/ci.yaml	Updated all action references from version tags to specific commit SHAs for reproducibility.
.github/workflows/docs.yaml	Updated all action references from version tags to specific commit SHAs, including deploy job actions.
.github/workflows/update-pre-commits.yaml	Updated all action references from version tags or branches to specific commit SHAs for reproducibility.

Poem

In the garden of code, commits now bloom,
Each action pinned, dispelling the gloom.
No more floating tags adrift in the breeze,
Just hashes and versions, for workflows at ease.
Hop, hop, says the rabbit, with a satisfied cheer—
Our builds are now stable, precise, and clear!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Pin all GitHub Actions used in the project using their git hash. This is a step up on security requested by zizmor 1.6.0: https://woodruffw.github.io/zizmor/release-notes/#v160

pinact is a handy tool used to hash them on the first iteration: https://github.com/suzuki-shunsuke/pinact

They all are expected to work with dependabot from now on: dependabot/dependabot-core#5951
