Use Composer's internal API to access ::getInstalledPackages()

Problem/Motivation

We currently use \Drupal\package_manager\ComposerUtility::getInstalledPackagesData to access Composer's installed.php data. That works today, of course, but it might be better (safer) to use Composer's own code API to shield ourselves from future implementation detail changes in Composer.

Proposed resolution

\Composer\InstalledVersions::getInstalledPackages() seems like the obvious API candidate, but it's dependent on its own __DIR__, without a way to specify an alternative path. Therefore, it can't be used as-is from the active directory on the staging directory. There are a few possible workarounds to this limitation, each with their own benefits and drawbacks which will not be fully outlined here:

  • Fork the class, making it possible specify a path
  • In the appropriate request, modify the class loader at runtime to point to the class in the staging directory
  • Find an alternative approach that doesn't involve using installed.php at all.

We may find some inspiration in these libraries:
