Walkthrough

The recent updates focus on enhancing thread safety and performance in the SofaTracerSpan class by changing the logs data structure from a LinkedList to a ConcurrentLinkedQueue. Corresponding test cases in SofaTracerSpanTest were also updated to reflect these changes, ensuring accurate and reliable testing of the new data structure.

Changes

Files/Paths Change Summary
tracer-core/src/main/java/com/alipay/common/tracer/core/span/SofaTracerSpan.java Updated logs data structure from LinkedList to ConcurrentLinkedQueue for thread safety.
tracer-core/src/test/java/com/alipay/common/tracer/core/span/SofaTracerSpanTest.java Updated test cases to use ConcurrentLinkedQueue<LogData> instead of List<LogData>.
Added necessary imports and converted ConcurrentLinkedQueue<LogData> to ArrayList<LogData>.

Poem

In the heart of code, a change so grand,
Logs now flow through safer land.
From linked lists to queues that shine,
Thread-safe paths in every line.
Tests now dance in queue's embrace,
Ensuring logs maintain their grace.
Cheers to code that’s swift and bright,
A rabbit’s joy in every byte! 🐇✨

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 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 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 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.

29-29: Import of Lists from Google Guava.

This import is necessary for converting ConcurrentLinkedQueue to ArrayList in test methods.


38-38: Import of ArrayList.

This import is used for type conversion in test methods where ConcurrentLinkedQueue is converted to ArrayList.


43-43: Import of ConcurrentLinkedQueue.

This import is essential for the changes made to use ConcurrentLinkedQueue instead of List for handling concurrency in log data.


242-242: Use of ConcurrentLinkedQueue for log data handling in tests.

The replacement of List with ConcurrentLinkedQueue in these test methods aligns with the changes in the main class to handle concurrency issues effectively.

Also applies to: 265-265, 296-297, 324-327, 341-341, 355-356
