Resolve types through the DBAL TypeProvider interface

GromNaN · GromNaN · commit c1273c9f5bcb · 2026-08-05T12:32:19.000+02:00
DBAL 4.5 exposes Configuration::getTypeProvider() returning the new Doctrine\DBAL\Types\TypeProvider interface rather than the final TypeRegistry, so the type source is no longer required to be that concrete class. Renamed TypeRegistryLocator to TypeProviderLocator accordingly, along with the $typeRegistry properties and locals it feeds. The declared types are unions of TypeProvider and TypeRegistry, because the interface only exists as of DBAL 4.5 while these code paths still support older versions. PHP matches the first applicable member of a union and never loads the other, so the union resolves fine when TypeProvider is absent, whereas a sole TypeProvider type would raise a TypeError. Every such union sits on a private property, a private parameter, or the @internal locator, so none of it reaches the public API. DatabaseDriver now reads Column::getTypeName() instead of looking a name back up from an instance, which drops two deprecated calls at once. SqlWalker's deprecated TypedExpression branch keeps using Type::lookupName(), since a Type instance is all it has; both are deprecated and will be removed together.
