Reason for This PR

ref: roadrunner-server/roadrunner#1986
close: roadrunner-server/roadrunner#2000

Description of Changes

  • Since endure v2 we don't need to have a central place to shutdown pools of workers. So every plugin can independently maintain its own pool.
  • Fix incorrect pipeline.Int parsing.

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.

90-111: Enhanced Type Handling in Int Method

The modifications to the Int method significantly improve its ability to handle various data types. The use of a type switch to accommodate strings and different integer types is a robust solution. However, consider adding a comment explaining the choice of strconv.ParseInt with a base of 10 and a bit size of 64, as this might not be immediately clear to all developers.


205-226: Improved Flexibility in Priority Method

The updates to the Priority method align well with the changes in the Int method, enhancing the handling of various data types. The method's ability to parse strings and handle different integer types ensures that it can accommodate a wider range of input configurations. Consider adding a similar comment as suggested for the Int method to maintain consistency and clarity across the codebase.

223-230: Proper cleanup of worker pools implemented.

The addition of a deferred function to stop the worker pool is a good practice. The use of mutex ensures thread safety, which is crucial in concurrent environments. However, it's important to verify that the context passed to the Destroy method is handled correctly to avoid potential deadlocks or excessive blocking.

Run the following script to verify the context handling and potential deadlocks:

Verification successful

Context handling in Destroy method is robust.

The Destroy method in plugin.go correctly uses a context with a timeout to prevent indefinite blocking during the driver stop operation. The context is canceled after use, ensuring proper resource management. This implementation effectively mitigates potential deadlocks and handles contexts appropriately.

  • The method spans lines 544 to 575 in plugin.go.
Scripts executed

The following scripts were executed for the analysis:

#!/bin/bash
