Our Pull Request Approval Process

We have these basic policies to make the approval process smoother for our volunteer team.

Testing Your Code

Please make sure your code passes all tests. Our test code coverage system will fail if these conditions occur:

  1. The overall code coverage drops below the target threshold of the repository
  2. Any file in the pull request has code coverage levels below the repository threshold
  3. Merge conflicts

The process helps maintain the overall reliability of the code base and is a prerequisite for getting your PR approved. Assigned reviewers regularly review the PR queue and tend to focus on PRs that are passing.

Reviewers

Do not assign reviewers. Our Queue Monitors will review your PR and assign them.
When your PR has been assigned reviewers contact them to get your code reviewed and approved via:

  1. comments in this PR or
  2. our slack channel

Reviewing Your Code

Your reviewer(s) will have the following roles:

  1. arbitrators of future discussions with other contributors about the validity of your changes
  2. point of contact for evaluating the validity of your work
  3. person who verifies matching issues by others that should be closed.
  4. person who gives general guidance in fixing your tests

CONTRIBUTING.md

Read our CONTRIBUTING.md file. Most importantly:

  1. PRs with issues not assigned to you will be closed by the reviewer
  2. Fix the first comment in the PR so that each issue listed automatically closes

Other

  1. 🎯 Please be considerate of our volunteers' time. Contacting the person who assigned the reviewers is not advised unless they ask for your input. Do not @ the person who did the assignment otherwise.
  2. Read the CONTRIBUTING.md file make

41-44: Improved file reading with UTF-8 encoding

The changes in the file reading operation are beneficial:

  1. Specifying UTF-8 encoding ensures proper handling of different character encodings.
  2. The use of bool() on the search result guarantees a boolean return value.

These improvements enhance the robustness of the file reading operation.

Consider using any() with a generator expression for a slight optimization:

return any(eslint_disable_pattern.search(line) for line in file)

This approach would stop reading the file as soon as a match is found, potentially improving performance for large files.


45-47: Improved error handling for file reading

The addition of exception handling is a good improvement:

  1. It prevents the script from crashing due to file access issues.
  2. The error message provides useful information for debugging.

Consider using a logging module instead of print for error reporting. This would allow for more flexible log management:

import logging

# At the beginning of the script
logging.basicConfig(level=logging.ERROR)

# In the exception handler
logging.error(f"Error reading file {file_path}: {e}")

Also, consider raising a custom exception or returning a distinct value (e.g., None) instead of False for error cases. This would allow the calling function to distinguish between "no eslint-disable found" and "error occurred while checking".

package.json (1)

72-72: Approve change with suggestions for improvement

The modification to the lint:check script successfully addresses the PR objective by adding a check for eslint-disable comments. This change will help enforce better adherence to linting standards.

However, I have two suggestions for improvement:

  1. Consider using a more portable way to invoke Python, such as node -e "require('child_process').spawn('python', ['.github/workflows/eslint_disable_check.py'], {stdio: 'inherit'})". This ensures compatibility across different environments where Node.js is guaranteed to be present.

  2. Add a comment explaining the purpose of the added Python script, for example:

    "lint:check": "eslint \"**/*.{ts,tsx}\" --max-warnings=0 && python .github/workflows/eslint_disable_check.py # Check for eslint-disable comments"
.github/workflows/pull-request.yml (2)

59-59: Approve the addition of eslint_disable_check.py with suggestions for improvement

The addition of eslint_disable_check.py addresses the PR objective of fixing the eslint checker to detect eslint-disable comments. This is a good improvement to the workflow. However, I have a few suggestions:

  1. Use double quotes around ${CHANGED_FILES} to prevent potential issues with globbing and word splitting:

    run: npx eslint "${CHANGED_FILES}" && python .github/workflows/eslint_disable_check.py
  2. Consider running the Python script regardless of the ESLint result. This ensures that eslint-disable comments are caught even when there are other linting errors. You can achieve this by using ; instead of &&:

    run: npx eslint "${CHANGED_FILES}"; python .github/workflows/eslint_disable_check.py

59-59: Alignment with PR objectives and potential redundancy

The changes in this file align well with the PR objectives of fixing the eslint_disable_check.py script to detect eslint-disable comments. The script is now executed as part of the linting process (line 59), which directly addresses the issue.

However, I noticed that there's also a separate job "Check-ESlint-Disable" (lines 168-178) that runs the same script. While this provides an additional layer of checking, it might be redundant and could potentially slow down the overall workflow.

Suggestions:

  1. Consider consolidating these checks into a single execution, preferably in the linting step, to improve efficiency.
  2. If keeping both checks is intentional (e.g., for redundancy or different scopes), please add comments explaining the rationale to improve maintainability.

Also applies to: 168-178

39-40: Improved eslint-disable detection pattern

The new regular expression pattern is a significant improvement:

  1. It covers all variations of eslint-disable statements, including "eslint-disable-next-line" and "eslint-disable-line".
  2. The use of re.IGNORECASE ensures case-insensitive matching, making the detection more robust.

This change directly addresses the PR objective of improving detection of eslint-disable statements.


39-47: Summary: Significant improvements in eslint-disable detection and error handling

The changes in this PR successfully address the main objectives:

  1. The new regex pattern significantly improves the detection of various forms of eslint-disable statements, including the previously missed cases.
  2. The addition of error handling makes the script more robust against file reading issues.
  3. The use of UTF-8 encoding ensures proper handling of different character sets.

These improvements enhance the script's ability to enforce linting standards and maintain code quality. The PR effectively resolves the issue described in #2257.

To ensure the changes work as expected, please run the following verification script:

This script will help verify that the changes correctly detect various eslint-disable patterns and that the script exits with an error code when such patterns are found.

Line range hint 223-231: Approve the addition of the Check-Target-Branch job

The new "Check-Target-Branch" job is a valuable addition to the workflow. It enforces good branching practices by ensuring that all pull requests are targeted to the 'develop' branch. This helps maintain a clean and organized development workflow.

Key benefits:

  1. Prevents accidental merges into incorrect branches.
  2. Provides clear guidance to contributors by referencing PR_GUIDELINES.md in the error message.
  3. Runs independently, allowing for quick feedback without waiting for other checks.

This addition will help streamline the PR process and reduce potential mistakes.
