Walkthrough

The code changes introduce a new feature that enables users to fetch the halt_height from a node's configuration via the gRPC endpoint. This update allows external systems to monitor and alert on the approach of the halt height, a critical value indicating when a blockchain node will stop processing blocks, usually in preparation for an upgrade or maintenance.

Changes

File Path Change Summary
CHANGELOG.md Added entry for the addition of halt_height to the gRPC /cosmos/base/node/v1beta1/config request.
api/.../v1beta1/query.pulsar.go
client/grpc/node/service.go
Added halt_height field to the ConfigResponse struct.
client/grpc/node/service_test.go Updated TestServiceServer_Config to include halt_height and added an assertion to check its value.
proto/cosmos/base/node/v1beta1/query.proto Added halt_height field of type uint64 to the ConfigResponse message and reformatted minimum_gas_price.

Assessment against linked issues

Objective Addressed Explanation
Enable fetching the halt-height of a specific node via the API it exposes (LCD or Tendermint/CometBFT API). [#19032] -
Support the retrieval of halt-height to facilitate building alerts for upcoming upgrades and chain halts. [#19032] -
Facilitate the calculation of time remaining before a halt-height is reached. [#19032] The addition of halt_height allows external systems to calculate the remaining time.
Expose the halt-height metric from the exporter for Prometheus scraping. [#19032] The changes do not directly indicate the exposure of halt_height for Prometheus scraping.
Provide an API method to retrieve the node's halt-height, considering potential limitations or security concerns. [#19032] The addition of halt_height to the gRPC endpoint is a secure method to expose this information.

The code changes appear to address most of the objectives outlined in the linked issue. However, it is not clear from the changes alone whether the halt_height metric has been made available for Prometheus scraping, which would require additional context or code outside the scope of the provided snippets.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

Note: Auto-reply has been disabled for this repository by the repository owner. The CodeRabbit bot will not respond to your comments unless it is explicitly tagged.

  • 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

The new assertion correctly checks if the HaltHeight in the response matches the defaultCfg. Consider adding a test case to cover scenarios where HaltHeight is set to a non-default value.
