When introduced in #51514, the behavior of group selection was wrong and introduced BC breaks (see the two related issues).
This PR resolves them by making that behavior opt-in, hidden behind an
enable_default_groupscontext value.Plus, this PR handles (when opted-in) default groups as they should have been handled in the first place.
Let's say we have the following class:
The
SerializerExtractorwill return properties:null,*,[]noGroup,customGroup,defaultGroup,classGroupcustomcustomGroupDefault,Foo,[]noGroup,defaultGroup,classGroupThe
AbstractNormalizerwill allow attributes:null,[],*noGroup,customGroup,defaultGroup,classGroupcustomcustomGroupDefault,FoonoGroup,defaultGroup,classGroupThe
MetadataAwareNameConverterwill allow attributes:null,[]noGroup,defaultGroup,classGroup*noGroup,customGroup,defaultGroup,classGroupcustomcustomGroupDefault,FoodefaultGroup,classGroupOn the contrary to
SerializerExtractorandAbstractNormalizer,noGroupis not included when any group is specified, andcustomGroupis not included when no group is specified)Another PR should be created in 7.3 in order to deprecate not setting the
enable_default_groupscontext value, as it will default totruein 8.0.
