Composer/Xdebug-Handler
Restarts CLI processes without loading the Xdebug extension to improve performance.
What is Composer/Xdebug-Handler?
Composer Xdebug Handler is a PHP library that automatically restarts command-line interface (CLI) processes without loading the Xdebug extension, unless it's explicitly disabled. It solves the performance overhead of Xdebug during routine tasks like dependency management by transparently restarting processes in an Xdebug-free environment. Originally part of Composer, it is now a standalone tool for seamless integration into PHP CLI applications.
PHP developers working with command-line tools or scripts that need to avoid Xdebug's performance impact during non-debugging operations, such as running Composer, PHPUnit, or other CLI-based utilities. It is particularly useful for tool maintainers who want to ensure their applications run efficiently without requiring users to manually disable Xdebug.
Developers choose this library because it automatically handles the restart process transparently, eliminating the need for manual configuration or user intervention. Its unique selling point is the ability to keep Xdebug available for debugging while avoiding its slowdown in everyday CLI tasks, with extensible design for custom restart logic and support for persistent settings across sub-processes.
