We recommend that you space out your commits to avoid hitting the rate limit.

How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.
Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.
Please see our FAQ for further information.

Walkthrough

The ratelimit package has been extensively updated, focusing on enhancing its integration with IBC middleware. It involves modifications across several files to refine the handling of IBC packets, parsing of IBC denoms, and utility functions, by incorporating and adapting the Stride x/ratelimit implementation. These changes include updates to licensing references, import adjustments, and augmenting the keeper package's capabilities to support the middleware's requirements more effectively.

Changes

Files Change Summary
.../ratelimit/ibc_middleware.go Removed previous attribution message, modified imports.
.../ratelimit/keeper/packet.go
.../ratelimit/util/ibc.go
.../ratelimit/util/parse_denom.go
Updated to include methods for IBC packet processing, IBC utility functions, and parsing IBC denoms. Adapted from Stride x/ratelimit with updated licensing information.

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-tests for this file.
  • 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 tests 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 from git and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit tests.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.

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.

CodeRabbit Commands (invoked as PR comments)

  • @coderabbitai pause to pause the reviews on a PR.
  • @coderabbitai resume to resume the paused reviews.
  • @coderabbitai review to trigger a review. This is useful when automatic reviews are disabled for the repository.

The import section has been modified to include specific versions of the ibc-go modules, using v8. Ensure that these versions are compatible with the rest of the project and that no deprecated APIs are being used. The nolint:staticcheck directive on the clienttypes import suggests that there might be a deprecated or unused import. Verify if this is necessary and consider updating the code to use a non-deprecated version if possible.

The implementation of OnRecvPacket has been modified to include rate-limiting logic by calling IncrementCapacitiesForDenom. Ensure that this logic correctly handles all edge cases, especially around error handling and state changes. The comment mentions that if the Recv fails on the underlying transfer stack, the state change is not committed. This is critical for maintaining consistency but requires thorough testing to ensure it works as intended, especially in failure scenarios.

The error handling in OnAcknowledgementPacket and OnTimeoutPacket methods logs errors but also returns them, which is a good practice. However, ensure that the error messages are clear and provide enough context for debugging. Also, verify that all error paths have been considered and appropriately tested, especially in scenarios where packet processing fails.

The SendPacket and WriteAcknowledgement methods implement custom logic for rate-limited packet sending and acknowledgement writing. It's important to ensure that these methods correctly enforce rate limits without introducing bottlenecks or unintended side effects. Specifically, verify the performance implications of these methods under high load and ensure that they do not negatively impact the overall throughput of the IBC middleware.

The GetAppVersion method returns the application version of the underlying application. Ensure that this method's implementation aligns with the expectations of the IBC protocol and that it correctly handles any edge cases, such as when the app version is not set or is incompatible with the counterparty chain.
