Walkthrough

The pull request introduces a new CustomRevert library in Solidity, which provides a mechanism for reverting transactions with custom error messages. It includes three overloads of the revertWith function to handle different argument types: a basic selector, a selector with a uint256, and a selector with an address. The library uses inline assembly for efficient memory manipulation and ensures memory safety by exiting the call context immediately after the revert operation.

Changes

Files Change Summary
contracts/src/utils/libraries/CustomRevert.sol Added CustomRevert library with three revertWith functions for custom error handling.

11-16: Efficient use of assembly for reverting with a selector.

The implementation uses inline assembly effectively to revert with a selector. However, ensure that the "memory-safe" claim is verified through thorough testing.


18-25: Proper memory handling for reverting with a selector and uint256.

The function correctly manages memory for a selector followed by a uint256. Ensure the "memory-safe" claim is verified through thorough testing.


27-34: Correct implementation for reverting with a selector and address.

The function properly masks and stores the address, ensuring correct memory usage. Verify the "memory-safe" claim through thorough testing.

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>.
    • 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 generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @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.
