Summary of Changes

Hello, 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 implements a temporary strategy to manage the concurrency of Cloud Run function deployments. It introduces a dedicated executor with a strict concurrency limit of two for these specific operations, aiming to mitigate issues related to low zip deploy capacity. This change refactors the internal deployment mechanism by providing a specialized executor for Cloud Run function-related tasks.

Highlights

• Dedicated Executor for Cloud Run Functions: A new runFunctionExecutor has been introduced to specifically manage operations related to Cloud Run functions (creation, updates, and deletions), separating them from general executor tasks.
• Temporary Concurrency Throttling: The runFunctionExecutor is temporarily configured with a concurrency limit of 2 for Cloud Run function deployment operations. This measure aims to manage the concurrency limit of zip deploys due to low capacity.
• Fabricator Class Updates: The FabricatorArgs interface and the Fabricator class have been updated to incorporate and utilize the new runFunctionExecutor.

Code Review

This pull request introduces a dedicated runFunctionExecutor to manage operations for Cloud Run functions, including creation, updates, and deletions, by modifying the Fabricator class and its instantiation. The changes aim to separate the execution logic for Cloud Run functions from general function operations. Review feedback suggests two main improvements: first, ensuring that the runThrottlerOptions in src/deploy/functions/release/index.ts inherit retry and backoff settings from throttlerOptions for consistent and robust behavior, and second, refactoring the identical runFunctionExecutor and functionExecutor configurations in src/commands/functions-delete.ts to a shared constant to improve maintainability and reduce code duplication.
