  "message": "Add tests for string APIs for implicit presence fields.\n\nBy \"string APIs\", I mean the following APIs:\n- mutable_foo\n- set_allocated_foo\n- release_foo\nSee also: https://protobuf.dev/reference/cpp/cpp-generated/#implicit-string\n\nAdd the following test cases (for singular implicit-presence fields):\n- A single call to mutable_foo() should not result in additional serialization\n  on the wire.\n- Assigning an empty string to mutable_foo() should not result in additional\n  serialization on the wire.\n- Calling set_allocated_foo() with an empty string should not result in\n  additional serialization on the wire.\n- If a field is nonempty, release_foo() effectively clears the field (while\n  returning a pointer to the original data).\n\nAdding coverage for these behaviours can increase confidence when we introduce\ninternal hasbits to help with presence tracking for implicit presence fields.\nmutable_foo will in general set the hasbit, so the generated code will need to\ncheck that field is nonempty before serializing.\n\nPiperOrigin-RevId: 658562530\n",
