Summary of Changes

Hello @Royal-lobster, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request introduces a minor but significant improvement to the Pm2Service class by enhancing its resource management. The primary goal is to guarantee that the PM2 connection is always properly disconnected after data transmission attempts, thereby preventing potential resource leaks and ensuring the application's stability and efficiency.

Highlights

• PM2 Connection Management: Ensured that pm2.disconnect() is called after attempting to send data to a process within the Pm2Service class, preventing potential resource leaks by properly closing the PM2 connection regardless of success or failure.
• Code Clarity: Renamed the error parameter in the pm2.sendDataToProcessId callback from err to sendErr for improved readability and semantic clarity.

Code Review

This pull request aims to fix a resource leak by adding pm2.disconnect(). While the intention is correct, the current implementation introduces a critical race condition when sending messages to multiple processes. The first message sent will close the PM2 connection, causing subsequent messages to fail. I've added a comment explaining the issue in detail and outlining the necessary refactoring to correctly manage the connection lifecycle. The renaming of the err variable to sendErr is a good improvement for code clarity.

Code Review

This pull request correctly refactors the Pm2Service to manage PM2 connections more effectively, preventing potential resource leaks by ensuring pm2.disconnect() is always called. The new sendToProcesses method centralizes the logic for sending data to multiple processes. I have added a couple of suggestions to improve the robustness of the implementation: one to handle an edge case with an empty list of process IDs, and another to fix a subtle bug in the logic for filtering process IDs.
