GDExtension: _ready, _enter_tree, _process, etc. not being called anymore

[minoaut]

Godot version

v4.2.dev.custom_build [7e67b49]

System information

Ubuntu 23.04 Lunar Lobster

Issue description

After the latest Godot rebuild from git none of these virtual functions are called anymore:
void _ready() override;
void _enter_tree() override;
void _exit_tree() override;
void _process(double delta) override;
void _physics_process(double delta) override;

My project is borked, won't even start anymore. I'll include simple sample code below. I suppose all GDExtension code is affected.

Is this related to #80284? If yes how can I turn reloading of GDExtensions off?

Steps to reproduce

• unzip sample code
• cd gdextension_notifications_not_called
• make
• godot -e
• godot

expected output:
TestMesh::TestMesh()
TestMesh::_enter_tree()
TestMesh::_ready()
TestMesh::_process()
TestMesh::_physics_process()
...

actual output:
TestMesh::TestMesh()

Which commit of godot-cpp are you using? You need to use godotengine/godot-cpp@bf2f9e2 in order for it to be compatible with the latest Godot master.

I've definitely tested _ready and _process together with the hot reloading PRs, and they should be working fine.

I just checked in the MRP attached to this issue, and it's using godotengine/godot-cpp@c44c3d5 (one commit behind master) which is probably the source of the problem.

I also quickly retested with one of my test projects and the latest master of both Godot and godot-cpp, and _process and _ready were working fine!

I only ever fetch from latest Godot master. The latest commit was 7e67b49. It's in the godot version above.
I thought too I must have done something wrong, but there was nothing I changed except from pulling the latest Godot. The sample code seemed to confirm there is an issue, so here I am :).

I'm talking about godot-cpp master. In your MRP, you've got godot-cpp at godotengine/godot-cpp@c44c3d5 whereas you need to use godotengine/godot-cpp@bf2f9e2 for it to be compatible with Godot master.

(At least at the moment, if another change is made to Godot master that requires a companion change to godot-cpp, then you may need a newer commit in the future.)

I pulled https://github.com/godotengine/godot-cpp fresh before I posted. But I see there's a new commit now. Let me try.

Yep, sample gets notifications again. Big project still crashes on Intel but runs now on NVIDIA at least. Different issue.
I guess I picked an unlucky time to upgrade. Thanks for your help.
