change syncing query logic

[sh-cha]

Summary by CodeRabbit

• New Features
  • Updated synchronization status endpoint to return a positive response if either the host or child node is syncing, instead of requiring both to be syncing simultaneously.
  • Enhanced error handling with nil checks for syncing pointers.

Walkthrough

The pull request modifies the synchronization status checking logic in two separate files: challenger/challenger.go and executor/querier.go. In both files, the /syncing endpoint's response generation has been changed from requiring all nodes to be syncing (using logical AND) to returning a positive response if any node is syncing (using logical OR). Additionally, the new implementations include nil checks for the syncing pointers, enhancing error handling.

Changes

File	Change Summary
challenger/challenger.go	Modified /syncing endpoint to return true if either host or child node is syncing, with nil checks.
executor/querier.go	Updated /syncing endpoint to return true if any of the synchronization statuses (hostSync, childSync, batchSync) are true.

Poem

🐰 Sync or swim, we're changing the game,
OR logic leaps, no two nodes the same!
From AND to OR, our status takes flight,
Flexibility dancing, pure rabbit delight!
Synchronization's new rhythm rings clear 🌟

🪧 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>, please review it.
  • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @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.

challenger/challenger.go (1)

Line range hint 77-77: Review architectural change in sync status reporting.

The change from requiring all nodes to be syncing (AND) to any node syncing (OR) appears in both the executor and challenger components. While the change is consistent across components, consider:

1. Adding documentation explaining why this architectural change was made
2. Ensuring consistent null-checking patterns across both components
3. Updating integration tests to verify the new behavior
