setup-php claims that Xdebug is available for PHP 8.3.0-dev when it is not

[sebastianbergmann]

Describe the bug

For a couple of days now, PHP 8.3.0-dev does not seem to have a working Xdebug. Here is an example of the job for PHPUnit's main branch failing due to Xdebug not being available although ✓ xdebug Xdebug enabled as coverage driver is printed.

I know that Xdebug's master branch currently does not compile against PHP's master branch. I do think, however, that a message such as ✓ xdebug Xdebug enabled as coverage driver must not be printed when the extension in question is not available.

The header file changes in php/php-src#10216 have affected most extensions built along with PHP 8.3 in shivammathur/php-builder. I will work on adding patches for them in the build.

[sebastianbergmann]

This issue is not about the fact that an extension is currently broken, but about the fact that setup-php claims that an extension is loaded.
