Thread safety in plug-ins

Thread safety in plug-ins Learn about reentrancy for plug-ins and best practices to make them thread safe.

Overview

In FxPlug 4, the framework handles requests from the host application on a serial queue on a background thread of the plug-in. Many requests move to a concurrent queue for processing by your plug-in. This avoids blocking incoming requests from other threads. It also allows processing of requests sent asynchronously from the same thread in the host application.

This background processing means you need to be careful to not read from and write to the same objects or memory on different threads at the same time. This includes your plug-in’s instance variables and properties, and those of any other objects you access during your plug-in’s lifetime.
