This document covers changes between version 3 and version 4, and how you may update your code to adapt to them.
Version 3 pinned to the version 1 series of laminas/laminas-httphandlerrunner, which defined the class
mezzio-swoole extended that class via its own implementation
Version 4 of mezzio-swoole pins to version 2 of laminas/laminas-httphandlerrunner.
laminas-httphandlerrunner v2 introduces
Laminas\HttpHandlerRunner\RequestHandlerInterface, and has its
Laminas\HttpHandlerRunner\RequestHandlerRunner class implement this new interface; additionally, the class now marks itself final, which prevents extension, and thus requires a change in mezzio-swoole's implementation.
Additionally, the base Mezzio package adopted laminas-httphandlerrunner v2.1 as its minimum supported version starting with its 3.8.0 release, and modified its
Mezzio\Application class constructor to typehint against
Laminas\HttpHandlerRunner\RequestHandlerInterface instead of
The result is that mezzio-swoole v3 releases cannot be used with Mezzio versions 3.8 and newer.
For version 4,
Mezzio\Swoole\SwooleRequestHandlerRunner now implements
Laminas\HttpHandlerRunner\RequestHandlerInterface, but does not extend
Laminas\HttpHandlerRunner\RequestHandlerRunner (as it cannot).
Further, the class is now marked final.
As such, you can no longer extend
To change behavior of the class, we recommend using its event system and attaching listeners to shape its behavior.
