@navarr Transferred this into the Warden issue tracker. The upstream base PHP images don't provide Xdebug, it's layered into the Warden images via the Dockerfiles in here.

It seems what is happening is, there is no Xdebug2 for PHP 8, and instead of failing the build it's installing the xdebug3 package automatically when php-pecl-xdebug is installed:

Does this still occur if you include PHP_XDEBUG_3=1 in your .env file? Assuming it does not (and it shouldn't, given the work in #279 introduced these Xdebug3 ready images with the newer configuration settings), then it sounds like the debug image variant builds need to be blocked for PHP 8 and PHP_XDEBUG_3=1 forcefully set when PHP_VERSION is >= 8.0 since Xdebug 2 isn't supported. And there should probably be a note in the docs regarding this.

Thoughts?

@davidalger Good call, I must've missed that update. This issue does not occur with PHP_XDEBUG_3=1 in the .env file.

Forcing it for 8.0+ is probably the right call.

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs.
