Fixed span clone concurrency issues #518

ZijieSong · 2024-05-27T02:43:08Z

Motivation:

When using com.alipay.common.tracer.core.span.SofaTracerSpan#cloneInstance, it may lead to concurrency safety issues.

Modification:

Change the class that causes concurrency issues: linkedhashmap, to concurrenthashmap. Note that there may be a loss of order here, but there is no need for insertion order in the code, so this modification can be made.

Summary by CodeRabbit

Updates
- Updated version from 3.1.3 to 3.1.4-SNAPSHOT across various components for consistency and future enhancements.
Improvements
- Enhanced thread safety by replacing LinkedHashMap with ConcurrentHashMap for tag storage in SofaTracerSpan.
Tests
- Added file handling logic in SofaTracerTest to improve test robustness.
- Included error message printing in TestUtil for better debugging during test failures.

Walkthrough

The changes primarily consist of updating the version from 3.1.3 to 3.1.4-SNAPSHOT across various pom.xml files in multiple modules, ensuring consistency. Additionally, thread safety improvements were made in SofaTracerSpan.java by replacing LinkedHashMap with ConcurrentHashMap. Minor updates to test files include adding file handling logic and error messaging.

Changes

Files/Modules	Change Summary
`pom.xml`, `sofa-tracer-plugins/.../pom.xml`, `tracer-all/pom.xml`, `tracer-core/pom.xml`, ...	Updated version from `3.1.3` to `3.1.4-SNAPSHOT` in parent artifact configuration.
`tracer-core/src/main/java/com/alipay/common/tracer/core/span/SofaTracerSpan.java`	Replaced `LinkedHashMap` with `ConcurrentHashMap` for thread-safe tag storage.
`tracer-core/src/test/java/com/alipay/common/tracer/core/tracertest/SofaTracerTest.java`	Added file handling logic and imports for file operations.
`tracer-core/src/test/java/com/alipay/common/tracer/core/TestUtil.java`	Added a `System.out.println` statement to print an error message along with the assertion during a catch block.

Poem

In the world of code, where versions bloom,
We updated numbers, and cleared some room.
From 3.1.3 to 3.1.4, we leap,
With ConcurrentHashMap, thread safety we keep.
Tests now handle files with care,
For a smoother run, everywhere.

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.

42-42: Import of ConcurrentHashMap is correctly added to support thread-safe operations on maps.

58-58: Switching to ConcurrentHashMap for tagsWithStr enhances thread safety, aligning with the PR's objective to fix concurrency issues.

60-60: Using ConcurrentHashMap for tagsWithBool is appropriate for concurrent access, ensuring thread safety.

62-62: The replacement of LinkedHashMap with ConcurrentHashMap for tagsWithNumber is a prudent choice for managing concurrent modifications.

Ensure file resources are properly released.

The method FileUtils.readLines opens a file stream that should be properly closed to avoid resource leaks. Consider using a try-with-resources statement or manually closing the stream in a finally block.

Refactor to improve readability and maintainability.

The current implementation mixes file handling and business logic in a single block. Consider separating these concerns for clearer code. For example, file handling could be moved to a separate method, and the business logic could focus solely on processing the file contents.

Consider handling potential IOException more gracefully.

The current implementation throws an AssertionError if an IOException occurs. It might be more appropriate to handle this exception directly within the test, perhaps logging the error or using a more specific assertion to handle this case. This would make the test more robust and self-contained.
