GDScript: Fix common mismatched external parser errors (reverted) #94617

rune-scape · 2024-07-22T10:29:13Z

tried to make this simple and thorough without fundamentally changing how GDScriptCache or GDScriptAnalyzer works

adds a cache of external class nodes that have been requested to be resolved, that map to the GDScriptParserRef that owns the class node

then the external resolve code can use it to find the parser that owns the node it wants to resolve
this is all needed to accommodates multiple different parser trees of the same script in the dependency tree

https://github.com/Zylann/godot_heightmap_plugin was excellent in demonstrating weird edge cases, i feel confident this PR solves the issue generally

also added much more descriptive errors

fixes #94244

There's a failing unit test:

I can't speak to the implementation, but I confirm it fixes the regression from #92616 identified in #94244.

The Finally/lambda pattern used here seems new in the codebase. It's local to GDScriptAnalyzer so I'm not too concerned, I'll let the team evaluate whether they like this kind of approach.

rune-scape · 2024-07-23T12:22:22Z

the failing test helped me generalize it more, its much simpler and more robust now

modules/gdscript/gdscript_analyzer.cpp

vnen · 2024-07-23T14:54:43Z

It is a bit complex but it looks okay to me. I just really don't understand the need of Finally here. Is there a problem in executing the contents right away instead of postponing it to when the function returns?

rune-scape · 2024-07-23T19:11:21Z

it searches the depended parsers of other parsers, so it has to be delayed until they actually resolve and call get_depended_parser_for or it might not yet depend on the parser we need

and the finally pattern is of course to make the code much cleaner

akien-mga

Approving as I tested it fixes the bug, and I need it for 4.3 RC 1.
Discussion can continue post-merge on implementation details.

I'm getting a nullptr exception at the bellow line when I try opening a scene after this PR.

godot/modules/gdscript/gdscript_analyzer.cpp

Line 3705 in 91eb688

p_from_class = p_from_class->base_type.class_type;

Coming from here:

godot/modules/gdscript/gdscript_analyzer.cpp

Line 891 in 91eb688

 Ref<GDScriptParserRef> parser_ref = ensure_cached_parser_for_class(p_class, nullptr, vformat(R"(Trying to resolve class member "%s" of "%s" from "%s")", member.get_name(), p_class->fqcn, parser->script_path), p_source); 

I don't know how the analyzer system works but the second argument (which is p_from_class) is nullptr so this code path always throws an exception.

Could you try and confirm? I couldn't reproduce the crash in a couple projects I tested.

Edit: Well that might fix the crash but then it will raise the parser bug below:

push_error(vformat(R"(Parser bug: Could not find external parser. (%s))", p_context), p_source);

Moving the while statement causes an infinite loop for scripts that didn't trigger the exception before.
Both changes by vnen fixes the crash but triggers the "Parser bug: Could not find external parser ..." error.

mihe · 2024-07-24T14:36:21Z

I can confirm that both suggestions by @vnen resolves the crash but instead results in the errors mentioned by @ydeltastar.

This maybe isn't the most minimal of MRPs, but it does reproduce the crash/regression mentioned above: cached-parser-crash.zip

It's essentially just a clean project with the Cheatsheet add-on added to it, but with one tiny modification done to it, which is that scripts/cheatsheet.gd now references scripts/argument.gd, specifically in its register function (although the location doesn't seem to matter):

func register(name: String, callback: Callable) -> Command:
	var command := db.register(name, callback)
+	if not command.args.is_empty():
+		print(command.args[0].name)
	commands_changed.emit()
	return command

That modification causes the crash, and without that modification the project loads just fine.

EDIT: There's a more minimal MRP here as well: #94697 (comment)

Reverted for now with #94723 to fix the new regression, which is more critical than the one fixed by this PR.
