Introduction

In the world of Minecraft server development, log stripping is a crucial feature that helps maintain the server's performance and stability. However, a common misconception has led to a block place event being dispatched when stripping a log. This unexpected behavior has caused issues with plugins, such as unwanted tags being applied. In this article, we will delve into the details of this issue, explore the expected and observed behavior, and provide a minimal plugin to reproduce the problem.

Expected Behavior

When stripping a log, no block place event should be dispatched. This is because log stripping is a maintenance task that involves removing logs from the server, rather than placing new blocks. The expected behavior is that the server should simply remove the logs without triggering any block place events.

Observed/Actual Behavior

Unfortunately, the observed behavior is that a block place event is dispatched when stripping a log. This means that plugins that rely on block place events may be triggered unnecessarily, leading to issues such as unwanted tags being applied. This behavior is not only unexpected but also causes problems for plugin developers.

Steps/Models to Reproduce

To reproduce this issue, a minimal plugin is available on GitHub. The plugin, called MinimalPlugin, can be found at https://github.com/Djaytan/minimal-papermc-plugin/tree/log-strip-place-issue. This plugin is designed to demonstrate the issue and can be used as a starting point for further investigation.

Plugin and Datapack List

The following plugins and datapacks are enabled on the server:

Plugins:
- MinimalPlugin
Datapacks:
- vanilla (built-in)
- file/bukkit (world)
- paper (built-in)

Paper Version

The server is running Paper version 1.21.4-207-main@1a7288a (2025-03-09T18:15:59Z), which is the latest version. The previous version was 1.21.4-117-a35cfe9 (MC: 1.21.4).

Other

The unexpected behavior caused by log stripping has led to issues with plugins, such as unwanted tags being applied. For more information, please refer to the discussion on SpigotMC here.

Conclusion

In conclusion, log stripping is mistakenly considered as a block place action, leading to unexpected behavior and issues with plugins. The expected behavior is that no block place event should be dispatched when stripping a log. However, the observed behavior is that a block place event is dispatched, causing problems for plugin developers. By understanding this issue and using the minimal plugin provided, developers can work towards resolving this problem and creating a more stable and efficient Minecraft server.

Introduction

In our previous article, we explored the issue of log stripping being mistakenly considered as a block place action, leading to unexpected behavior and issues with plugins. In this Q&A article, we will address some of the most frequently asked questions related to this issue.

Q: What is log stripping, and why is it important?

A: Log stripping is a maintenance task that involves removing logs from the server. It is an important feature that helps maintain the server's performance and stability. Logs can consume a significant amount of resources, and removing them can help prevent issues such as lag and crashes.

Q: Why is a block place event being dispatched when stripping a log?

A: The block place event is being dispatched because the server is treating log stripping as a block placement action. This is a misunderstanding of the log stripping process, and it is causing the issue.

Q: What are the consequences of this issue?

A: The consequences of this issue include unwanted tags being applied to blocks, which can cause problems for plugin developers. Additionally, the issue can lead to lag and crashes, as the server is consuming unnecessary resources.

Q: How can I reproduce this issue?

A: To reproduce this issue, you can use the minimal plugin provided on GitHub. The plugin is designed to demonstrate the issue and can be used as a starting point for further investigation.

Q: What are the steps to resolve this issue?

A: To resolve this issue, you can follow these steps:

Update to the latest Paper version: Ensure that the server is running the latest version of Paper.
