Set prepend-autoloader to false in composer.json

[nicolas-grekas]

This should allow e.g. symfony/yaml users to test their code with the latest version of the component, whereas today the phar users are forced to whatever version is bundled inside it.

What does composer.json have to do with the PHAR version of PHPUnit?

[nicolas-grekas]

Right, too quick :) So, the phar version is not autoloaded but "require" all files at bootstrap? Can't we use an autoloader here (a custom one to now collide with composer's)?

PHPUnit does use a map based autoloader in the PHAR distributed verison, afaik generated by phpab.

But that aside, how would changing the order of autoloading fix the underlying issue you describe?
(Assuming, I understood the problem correctly..)

Your application under test and PHPUnit share the same process space, so you'll always end up with a conflict in case the application and PHPUnit use the same library but in different versions.

Changing the order of loading them won't fix that.

[sebastianbergmann]

@nicolas-grekas is correct that the PHAR distribution of PHPUnit does not use an autoloader but instead loads all the sourcecode files from the PHAR on startup. This is done to make sure that no other autoloader prevents PHPUnit from loading its classes from the PHAR.

I will not change the way class loading works for the PHAR. If the PHAR does not work for you then do not use the PHAR.

The real problem that @nicolas-grekas wants to solve, I think, is related to #2015. Somebody really needs to make https://github.com/webmozart/php-scoper usable.

👍 with #2015 thanks
