Caution

Review failed

The pull request is closed.

Warning

There were issues while running some tools. Please review the errors and either fix the tool’s configuration or disable the tool if it’s a critical failure.

🔧 eslint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

backend/src/build-system/context.ts

Oops! Something went wrong! :(

ESLint: 8.57.1

ESLint couldn't find the plugin "eslint-plugin-prettier".

(The package "eslint-plugin-prettier" was not found when loaded as a Node module from the directory "/backend".)

It's likely that the plugin isn't installed correctly. Try reinstalling by running the following:

npm install eslint-plugin-prettier@latest --save-dev

The plugin "eslint-plugin-prettier" was referenced from the config file in "backend/.eslintrc.js".

If you still can't figure out the problem, please stop by https://eslint.org/chat/help to chat with the team.

Walkthrough

This pull request introduces a comprehensive error handling and validation framework across multiple build system handlers. The changes focus on implementing a robust error management strategy by introducing new error classes in errors.ts, enhancing input validation, and improving error propagation mechanisms. The modifications span various handlers in the backend, adding specific error types like RetryableError, NonRetryableError, and domain-specific errors to provide more granular error handling.

Changes

File	Change Summary
`backend/src/build-system/errors.ts`	Added comprehensive error hierarchy with `RetryableError` and `NonRetryableError` base classes
`backend/src/build-system/context.ts`	Added retry handling and global promise tracking mechanisms
`backend/src/build-system/retry-handler.ts`	Introduced new `RetryHandler` singleton for managing retry logic
Multiple handler files	Updated to use new error classes, improved input validation, enhanced error propagation

Poem

🐰 Errors dance, a coded ballet,
Retry and catch, they find their way
Robust and strong, our handlers sing
Of resilience that errors bring!
Code marches on, no fear in sight 🚀

🪧 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.
