fix return-stack-address violations #143

Closed ChibiDenDen closed 1 year ago

ChibiDenDen commented 1 year ago

While building the project, the following warning appears multiple times:

../godot-cpp/include/core/Godot.hpp:163:10: warning: returning reference to local temporary object [-Wreturn-stack-address] return a; ^ ../godot-cpp/include/core/Godot.hpp:285:34: note: in instantiation of member function 'godot::_ArgCast<const godot::Array &>::_arg_cast' requested here ret = (obj->f)(_ArgCast::_arg_cast(args[I])...); ^ ../godot-cpp/include/core/Godot.hpp:310:10: note: in instantiation of function template specialization 'godot::_WrappedMethod<godot::Fmod, float, unsigned long, const godot::Array &>::apply<0, 1>' requested here method->apply(var, obj, arg, typename construct_sequence<sizeof...(As)>::type{}); ^ ../godot-cpp/include/core/Godot.hpp:325:34: note: in instantiation of function template specialization 'godot::__wrapped_method<godot::Fmod, float, unsigned long, const godot::Array &>' requested here return (godot_wrapper_method)&wrappedmethod<T, R, As...>; ^ ../godot-cpp/include/core/Godot.hpp:343:42: note: in instantiation of function template specialization 'godot::get_wrapper_function<godot::Fmod, float, unsigned long, const godot::Array &>' requested here method.method = (__godot_wrapper_method)___get_wrapper_function(method_ptr); ^ ./src/godot_fmod.cpp:47:5: note: in instantiation of function template specialization 'godot::register_method<float (godot::Fmod::)(unsigned long, const godot::Array &)>' requested here register_method("get_event_parameter_by_id", &Fmod::get_event_parameter_by_id); ^

This is due to register_method not handling const references and instead returning a reference to a temporary stack variable.

This causes crashes on android on most API's as variants are not passed correctly.

Fixed and verified on android armv8

CedNaru commented 1 year ago

Do you have a log of the android crash ? I tested Android many times and never got one.

ChibiDenDen commented 1 year ago

@CedNaru I tested with godot 3.5.1 if it means anything, it works fine on windows but crashes on android when calling "play_one_shot"

Ill reproduce later today and provide logcat output if it helps. The fix itself does fix a memory bug in the existing c++ code that I think should be addressed regardless.

relevant logcat output from the second of the crash:

using play_one_shot_with_params will not crash, but instead print the following message (without playing a sound):

I never knew that registering const ref in Godot methods was ending up in that kind of issue (magic of C++ templates, I guess). But I see no issue with applying the changes. @bitbrain no need to pick that one for 4.0. From what I see, they added code to properly handle references and const references in the new version. It seems that it even became the standard.

@CedNaru good stuff. I see the builds are failing - probably still due to https://github.com/utopia-rise/fmod-gdnative/issues/95?

Yeah, don't know how to solve that. It seems that even having the person adding secrets on their own doesn't work.
