GDScript completion crashes when indexing a duplicate of the script from itself #57669

Open you-win opened 2 years ago

you-win commented 2 years ago

Godot version

3.4.2.stable

System information

Windows 10, AMD Ryzen 7 5800X, NVIDIA RTX 3080

Issue description

While writing a script, not while the game is running, when duplicating a Node's script from within the same script and then trying to access that duplicate script causes a segfault. Please note that the game was not run, simply typing something in the editor causes the crash.

Use case

I am dynamically creating new scripts at runtime. Instead of using a dummy node with a script attached, I thought it would be nice to simply duplicate the current node's script instead.

EDIT: I should mention that this works as expected is using a dummy node to copy from.

Steps to reproduce

Minimal reproduction code in a completely new project. There is no need to run the game.

extends Node

var dummy: GDScript

func _ready():
    dummy = get_script().duplicate()
    # start typing 'dummy.'
        # Typing the period character will cause a segfault

Calinou commented 2 years ago

I can confirm this on 3.x 49df809ca and master fc09d783f.

Note that the crash only occurs if test.tscn is open in the editor. If only the script is open, then I don't get a crash:

Stacktrace

For future reference: This is not a stack trace, as the origin of the crash isn't indicated. To get a stacktrace, you need to compile a build from source and run it with a debugger (if compiled with MinGW). If you don't want to use a debugger on Windows, you can compile with MSVC instead of MinGW and the built-in crash handler will work.

you-win commented 2 years ago

Apologies for the mixup in terminology, updated the initial issue. Glad to see it's reproduceable in any case

VikramSGIT commented 2 years ago

My observation about this issue is that Script don't have a duplicate() function.

Untitled-1

Instead of showing an error, it is mistaken as a Node when the duplicate() function is used. And also while debugging I found out that the get_script() function of Object returns a Variant but does contain sufficient info for GDScript (shouldn't be a problem?)

On further debugging native_type is misunderstood as Node instead of GDScript. Which lead to instancing the wrong method binder and crashing.

Untitled-1

I'll look deeper into the type detection algorithm...

SaracenOne commented 2 years ago

I have a bit more information on this. This specific code which appears to be causing trouble seems to be this in gdscript_editor.cpp

while (native_type.kind == GDScriptParser::DataType::SCRIPT) {
    if (native_type.script_type.is_valid()) {
        Ref<Script> parent = native_type.script_type->get_base_script();
        if (parent.is_valid()) {
            native_type.script_type = parent;
        } else {
            native_type.kind = GDScriptParser::DataType::NATIVE;
            native_type.native_type = native_type.script_type->get_instance_base_type();
            if (!ClassDB::class_exists(native_type.native_type)) {
                native_type.kind = GDScriptParser::DataType::UNRESOLVED;
            }
        }
    }
}

Specfically, the call get_instance_base_type is getting the node that the script inherits which is why 'duplicate' method bind is being called as a node rather than as a script resource. Replacing 'get_instance_base_type' with 'get_class_name' seems to fix the crash, but will require further investigation to ensure this change doesn't break other things. Also, errors (non fatal ones) still occur since in order to determine the types, the functions are being called internally, and since the duplicating the script requires reloading, this will tend to fail since it's already open. To more broadly solve stuff like this, maybe we should write a special case for native 'duplicate' functions to not actually call them, but just assume their type.
