Changelist

  • iavl upgrade fixes bugs
    • Legacy nodes being pruned when they are still being referenced
    • Hash incorrectly generated for some nodes that maintained child references to legacy nodes (but actually reference non-legacy nodes during tree modifications
    • SaveVersion incorrectly thinks that tree is unmodified if a previous leaf becomes the new root
  • turning fast nodes off because they are not supposed to be useful in iavl v1

Test Plan

  • Successfully synced on testnet and none of the bugs occur

Walkthrough

This update introduces a new configuration option within the base application initialization process. It specifically adds the ability to disable the fast node feature in the IAVL cache. This adjustment aims to provide users with more control over their application's performance and resource management, potentially optimizing for scenarios where the fast node's benefits do not outweigh its costs.

Changes

File Path Change Summary

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.
    • 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 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 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.
