Walkthrough

The updates reflect a shift in the Ethereum-based Cosmos transaction pool management, with a move away from certain Ethereum common library dependencies and a focus on both stateless and stateful transaction validation. Telemetry enhancements have been made to improve metrics collection for the mempool, and the CometBFT consensus algorithm's metrics have been renamed accordingly. The Ethereum Polaris API backend now better handles pending blocks, aligning with client expectations for the latest state information.

Changes

Poem

🐇✨ In the cosmos where code does weave,
A rabbit hopped with changes up its sleeve.
No more old ties, the pool's refined,
With telemetry stars, the metrics aligned. 🌟📊

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.
• @coderabbitai resolve resolve all the CodeRabbit review comments.
• @coderabbitai help to get help.

Additionally, you can add @coderabbitai ignore anywhere in the PR description to prevent this PR from being reviewed.

CodeRabbit Configration File (.coderabbit.yaml)

• You can programmatically configure CodeRabbit by adding a .coderabbit.yaml file to the root of your repository.
• The JSON schema for the configuration file is available here.
• If your editor has YAML language server enabled, you can add the path at the top of this file to enable auto-completion and validation: # yaml-language-server: $schema=https://coderabbit.ai/integrations/coderabbit-overrides.v2.json

cosmos/runtime/txpool/telemetry.go (1)

• 25-45: The addition of new metric keys with the prefix polaris_cometbft_ is consistent with the PR objectives to align telemetry with the CometBFT consensus algorithm. The new keys are well-named and follow the existing naming conventions.

cosmos/runtime/txpool/mocks/tx_sub_provider.go (1)

• 57-59: The Stats method has been added to the TxSubProvider mock without any implementation details. This is standard for a mock, as the actual implementation will be provided elsewhere.

cosmos/runtime/txpool/ante.go (1)

• 70-114: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [42-113]

The refactoring of the shouldEjectFromCometMempool method into validateStateless and validateStateful methods is in line with the PR objectives. The new methods are more descriptive and seem to separate concerns more clearly, which is a good practice for maintainability.

cosmos/runtime/txpool/mempool.go (1)

• 134-134: The addition of the MetricKeyMempoolKnownTxs telemetry counter within the Insert function is consistent with the PR's goal to enhance telemetry. It's incremented under the correct condition when a transaction is known but not causing a failure in CheckTx.

cosmos/runtime/txpool/handler.go (3)

• 45-45: The introduction of the statPeriod constant is a good practice for maintainability, as it avoids magic numbers and makes it clear what the value represents.
• 56-56: The addition of the Stats method to the TxSubProvider interface is consistent with the PR's objectives to enhance telemetry and performance monitoring.
• 181-201: > 📝 NOTE

This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [126-197]

The statLoop method is a new addition that periodically updates telemetry statistics. This is in line with the PR's objectives to introduce periodic telemetry updates. The method is well-structured and uses a ticker for periodic execution.

eth/polar/api_backend.go (3)

• 208-213: The modification to the HeaderByNumber method to return the latest state when a pending block is not available is a good change for client compatibility. It gracefully handles the case when the pending block is not available, which is an improvement over the previous behavior.
• 262-269: The BlockByNumber method has been updated to handle the case when the pending block is not available by returning the latest state. This change is consistent with the PR's objective to handle pending block scenarios more gracefully.
• 255-269: The BlockByNumber method's logic has been updated to improve client compatibility by handling pending block scenarios more effectively. This aligns with the PR's objectives and ensures that the API backend behaves predictably when the pending block is not available.

• 43-44: The maximum number of inbound peers has been increased from a previous value (not shown) to 40, and the maximum number of outbound peers has been decreased to 20. Confirm that these changes are aligned with the intended network capacity and security considerations.
