group logs by transaction hash when calculating bloom filter

[iuwqyir]

TL;DR

Improved logs bloom calculation to properly group logs by transaction and maintain order.

What changed?

Modified the CalculateLogsBloom function to:

• Group logs by transaction hash while preserving transaction order
• Process logs transaction by transaction
• Create a bloom filter for each transaction individually
• Combine transaction blooms into a single block bloom using bitwise OR operations

How to test?

1. Run validation tests that involve log bloom calculation
2. Compare bloom filter outputs with expected values from Ethereum nodes
3. Verify that blocks with multiple transactions containing logs produce the correct bloom filter

Why make this change?

The previous implementation treated all logs as if they belonged to a single transaction, which doesn't match Ethereum's approach of calculating bloom filters per transaction first. This change ensures our bloom filter calculation matches Ethereum's specification, where each transaction's logs contribute to the block bloom filter in the correct order, improving compatibility with Ethereum clients.

  • I pushed a fix in commit <commit_id>, please review it.
  • Explain this complex logic.
  • 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 explain this code block.
  • @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 explain its main purpose.
  • @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.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

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.
