Summary of Changes

Hello @joshlf, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the pre-push functionality by implementing exponential backoff for GraphQL queries. This change addresses potential issues with GitHub's resource limits when processing large batches of data, ensuring more reliable operation. Additionally, it removes an unnecessary dependency, itertools, which simplifies the project's dependency tree.

Highlights

• Dependency Removal: The itertools crate has been removed as a direct dependency.
• GraphQL Query Optimization: Implemented exponential backoff for GraphQL queries to handle resource limits imposed by GitHub, improving resilience and preventing failures when processing large batches.
• Resource Limit Handling: Added logic to detect RESOURCE_LIMITS_EXCEEDED or MAX_NODE_LIMIT_EXCEEDED errors from GitHub's GraphQL API and reduce batch size accordingly.

Changelog

• Cargo.lock
  • Removed itertools crate and its dependencies.
• Cargo.toml
  • Removed itertools dependency.
• src/pre_push.rs
  • Removed itertools import.
  • Implemented exponential backoff for GraphQL queries to handle GitHub resource limits.
  • Added error handling for RESOURCE_LIMITS_EXCEEDED and MAX_NODE_LIMIT_EXCEEDED GraphQL errors.
  • Adjusted batch processing logic to reduce batch size on resource limit errors.

Activity

• The PR introduces exponential backoff for GraphQL queries to handle resource limits imposed by GitHub.
• The PR removes the itertools dependency.

Code Review

This pull request introduces an exponential backoff mechanism for batched GraphQL queries, which is a robust improvement over the previous fixed-size chunking. This change will help avoid hitting GitHub's API resource limits. The implementation is sound, correctly handling backoff and retries. The logic for backoff, including the termination condition to prevent infinite loops, is well-thought-out. The removal of the itertools dependency is also a good cleanup. The suggestion to improve the readability of the error-checking logic is valid and has been retained.
