Problem

The inner instruction stack height isn't recorded after transaction processing so clients can't determine if an inner instruction was invoked by another inner instruction.

Summary of Changes

Builds on #28427

  • Record stack_height in a new InnerInstruction protobuf message type for each inner instruction
  • Add a new stack_height field to instruction data types returned by the RPC API

Related to #27736

We can't change CompiledInstruction and thus have to add a wrapper InnerInstruction, or what is it for?

Yes, exactly. Can't change CompiledInstruction in the sdk since it's used for transaction serialization. InnerInstruction is just a wrapper type.. it doesn't have to be specific to inner instructions but it's not necessary to record the stack height for transaction level instructions.

uint32 is that really necessary, the runtime itself only used 8 bits for the stack height.

Smallest size in protobuf is u32
