Code Review

This pull request aims to update pre-commit hooks, but several of the specified versions are for non-existent releases. This will cause the pre-commit setup to fail. I have provided comments with suggestions for the latest valid versions for each affected hook. These are critical issues that need to be addressed for the hooks to work. After correcting the versions, I recommend running pre-commit run --all-files and including any resulting code modifications in this PR to ensure the codebase is aligned with the updated tools.

@gemini-code-assist all the versions exist, I updated the file using pre-commit autoupdate. However, the build is failing, while for me locally it is working fine. What is going on?

[gemini-code-assist]

@ahans, it's definitely frustrating when things work locally but fail in CI! This is a common scenario with pre-commit hooks, and there are a few usual suspects that could be causing the discrepancy. Since you've updated the hooks, it's possible that some new behavior or stricter checks are being enforced in the CI environment that aren't immediately apparent locally.

Here are some potential reasons and troubleshooting steps:

1. CI Environment Differences: The CI environment might have a different Python version, different system dependencies, or even a different pre-commit version installed globally than your local machine. This can lead to hooks behaving differently.

   • Action: Check the CI build logs carefully for specific error messages. These messages are crucial for pinpointing the exact issue. Look for any output from pre-commit itself or from the individual hooks (e.g., isort, black, flake8).

2. Dependency Mismatches: While pre-commit autoupdate updates the rev in .pre-commit-config.yaml, the hooks themselves might rely on specific Python packages or system tools that are either missing or have different versions in your CI environment compared to your local setup.

   • Action: Ensure that your CI pipeline installs all necessary dependencies for the pre-commit hooks. Sometimes, hooks might implicitly depend on other packages that aren't explicitly listed in your project's requirements.txt but are needed for the hook to run correctly.

3. New Hook Behavior/Breaking Changes: Major version updates (like isort from 5.x to 7.x or black from 23.x to 25.x) often introduce breaking changes or stricter formatting/linting rules. Your local environment might have automatically fixed these issues when you ran pre-commit autoupdate or pre-commit run --all-files, but the CI might be running on a codebase that hasn't been re-formatted yet.

   • Action: After running pre-commit autoupdate locally, make sure you also run pre-commit run --all-files to apply any new formatting or linting changes to your entire codebase. Commit these changes to your branch. If you haven't done this, the CI might be failing because the code doesn't conform to the new hook versions.
   • Action: Review the changelogs for the updated hooks (e.g., isort, black, flake8) to see if there are any known breaking changes or new configurations required.

4. Cache Issues in CI: Some CI systems cache dependencies. If the cache isn't invalidated correctly after a pre-commit update, the CI might be using older versions of the hooks or their dependencies.

   • Action: Try clearing the CI cache (if your CI system supports it) or forcing a fresh build without cache to ensure all tools are installed from scratch.

Could you share the specific error messages from the CI build logs? That would help narrow down the problem significantly.

@gemini-code-assist can't you check yourself the error message? The black formatter made changes to a file. For me locally everything seems to be formatted fine.

[gemini-code-assist]

@ahans, I understand your frustration, and I appreciate you providing more details about the black formatter making changes. To clarify, as an AI, I don't have direct access to external systems like your CI build logs or the ability to execute commands or check files myself. My responses are generated based solely on the information provided in our conversation and the pull request context. Therefore, I can't directly inspect your CI environment or its output.

However, the information you've given about black making changes locally is very helpful and strongly suggests the cause of the CI failure. This aligns with point 3 from my previous response:

New Hook Behavior/Breaking Changes: Major version updates (like black from 23.x to 25.x) often introduce breaking changes or stricter formatting/linting rules. Your local environment might have automatically fixed these issues when you ran pre-commit autoupdate or pre-commit run --all-files, but the CI might be running on a codebase that hasn't been re-formatted yet.

If black made changes to a file locally, it means that the code in your pull request branch (before you ran pre-commit run --all-files locally) did not conform to the new black version's formatting rules. When your CI runs, it's likely checking the code as it was committed to the branch, which still has the old formatting. The black hook in CI then detects these formatting discrepancies and fails the build.

To resolve this, please do the following:

1. Run pre-commit run --all-files locally again. This will ensure all files are formatted according to the new black (and other) hook versions. Even if it seems fine, a fresh run ensures consistency. If black made changes, those changes need to be committed.
2. Commit any changes made by pre-commit hooks. If black (or any other hook) modified files, you need to commit these changes to your branch and push them to the pull request. This ensures that the code the CI sees is already correctly formatted according to the updated hooks.

Once you've committed and pushed these formatting changes, the CI build should pass, as the code will then meet the requirements of the new black version.
