Warning

Rate limit exceeded

@dwasse has exceeded the limit for the number of commits or files that can be reviewed per hour. Please wait 14 minutes and 34 seconds before requesting another review.

How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

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 recent changes significantly enhance the QuoteRequestHandler and Relayer struct to improve balance management and request handling in a concurrent environment. Key additions include new mutexes for locking balances, a method for committing pending balances, and improved synchronization in inventory checks. These modifications ensure safer concurrent access and bolster the reliability of the relayer service, ultimately streamlining the processing of quote requests.

Changes

Files Change Summary
services/rfq/relayer/service/... Enhanced QuoteRequestHandler to manage balance commitments with a new commitPendingBalance method; adjusted handleSeen and handleNotEnoughInventory methods for better synchronization with balance management.
services/rfq/relayer/service/... Added a balanceMtx mutex to the Relayer struct for synchronizing balance requests, improving concurrency control. Updated the NewRelayer constructor to initialize this new field.
services/rfq/relayer/service/... Introduced a balanceMtx mutex and getBalanceMtxKey helper function in QuoteRequestHandler to enhance thread safety and manage concurrent access to balance data.

🐰 In the meadow where bunnies play,
With balance locks and flows today,
We hop along, both swift and spry,
Making sure requests don't fly!
With mutex magic, all is bright,
Our relayer's strength takes flight!

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.

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 an incremental review. This is useful when automatic reviews are disabled for the repository.
  • @coderabbitai full review to do a full review from scratch and review all the files again.
  • @coderabbitai summary to regenerate the summary of the PR.
  • @coderabbitai resolve resolve all the CodeRabbit review comments.
  • @coderabbitai configuration to show the current CodeRabbit configuration for the repository.
  • @coderabbitai help to get help.

services/rfq/relayer/service/statushandler.go (2)

55-56: Improved concurrency management with balanceMtx.

The addition of balanceMtx enhances thread safety by managing concurrent access to balance-related data. This is a good practice for ensuring data consistency in a concurrent environment.


59-60: Utility of getBalanceMtxKey function.

The getBalanceMtxKey function provides a consistent way to generate keys for balance-related data, aiding in efficient data management and access.

services/rfq/relayer/service/relayer.go (2)

66-67: Improved concurrency management with balanceMtx.

The addition of balanceMtx to the Relayer struct enhances concurrency control by managing access to balance requests, which is crucial for maintaining data integrity in concurrent operations.


170-170: Proper initialization of balanceMtx.

The initialization of balanceMtx in the NewRelayer function ensures that the mutex is set up correctly, which is essential for preventing data races and ensuring thread safety.

services/rfq/relayer/service/handlers.go (3)

165-179: Improved control flow with commitPendingBalance.

Incorporating commitPendingBalance into handleSeen ensures that balance commitments are checked and managed early in the process, reducing the risk of issues with uncommitted balances.


Line range hint 182-212: Robust balance management with commitPendingBalance.

The commitPendingBalance method effectively manages balance locking and status updates, ensuring that concurrent requests are handled safely and efficiently.


Line range hint 512-534: Enhanced synchronization in handleNotEnoughInventory.

Including balance locking in handleNotEnoughInventory synchronizes inventory checks with balance management, improving the reliability of request handling.
