readonly vs aws_readonly confusing #33

Open hartmans opened 3 months ago

hartmans commented 3 months ago

So, I ran into a very similar issue with one of the AWS tests and discussed it in the chat room.

Background:

AwsManaged takes "aws_readonly" as an InjectionKey and sets the readonly property based on that injection.

That key has _optional=NotPresent meaning that if the key is not provided the property is not set.

Consequences

If aws_readonly is set, it will be inherited by all injectors.
If aws_readonly is not set in an injector then readonly will be respected for an object but not inherited.
If aws_readonly is set in an injector anywhere readonly will be ignored
readonly will not generally cascade into objects.
Setting aws_readonly as a class property in an InjectableModel will work, but will not work in a non-modeling class.
