I decided to add two additional PHP interpreter packages instead of an additional extension key. IPv6 support is part of PHP core (if enabled) and is not part of any optional extension.
- Move the version api getter to the PluginManager And make it such that it can be mocked, but not pollute the public interface. That means "protected" visibility.
- The plugin api version constant should still be used throughout the code.
- Use different fixtures class names
- Use regex possessive quantifiers for performance
- Use full words for readability
Instead of developing plugins against a single, fixed Plugin API version - `"composer-plugin-api": "1.0.0"`, this change will allow plugin developers to use versions like `"composer-plugin-api": "~1.1"` or `"composer-plugin-api": ">=2.1 <3.0"`, aka actual Composer-compatible constraints.
Only the "1.0", "1.0.0" and "1.0.0" Plugin API versions will be regarded as BC versions, and internally converted to "^1.0"; every other declared version string will be kept as it is.
Because of this new constraint flexibility, plugin version mismatches will be skipped, which means those plugin will NOT be registered to the system. Previously, a mismatch triggered a warning, but plugins were still registered.
This happens on "new PlatformRepository(array($somePackage))".
The parent constructor calls "\Composer\Repository\ArrayRepository::addPackage()",
which, on a brand new repo object, further calls "\Composer\Repository\PlatformRepository::initialize()"
and finally this iterates over a NULLd "$this->overrides", triggering the error.
These overrides are on the form
array($packageName => $version)
These "virtual" packages are added instead of the real ones,
with the version specified. Note that it is a version and not
a constraint so you cannot pass array('ext-mongo' => '*').
Also there is currently no limit what packages can be overriden.
