Build failure unrelated.

Does this mean that in the example mentioned in #24559 the inlined bar service is not removed anymore within RemoveUnusedDefinitionsPass with this fix?

👍 Should it not be merged into 3.4 instead of master?

Are you sure about it ? Bindings are used by the autowiring layer, which runs before the removal passes. If the autowiring has not used the binding to set a reference, we don't have a usage (and we don't need to prevent removal AFAIK). And if the binding was used to fill an argument, we will have a reference in the arguments (and so processed by the existing code)

@stof if the service was inlined this it not true I believe. It will have an inlined Definition in the arguments and not a Reference.

@dmaicher and this is fine as well, as the argument is still filled properly. It does not need the binding anymore.

Actually, I think the issue is that AbstractRecursivePass is always processing bindings in the exact same way it processes arguments, method calls and so on.
And so, it will treat any reference in a binding as a usage of the service. But once bindings are used to fill arguments, they become useless. So they should not be visited by the validator passes checking for circular references, invalid references and so on.
I'm not even sure there is a single case where a recursive pass should visit them.

@stof ok I see 😉 Then we should indeed not check the References contained in bindings I guess. So the Definitions can be removed correctly for inlined services.

can we have a test case for this? for example within the RemoveUnusedDefinitionsPassTest?

this test will now also pass without your change I believe? we should remove this line so the Reference a in the bindings does actually not exist on the container?

In #24602 we removed the processing of bindings from the `AbstractRecursivePass`. But there is actually one case where we want a recursive pass to process them: to resolve env param placeholders.
