Can't open project after deleting .godot folder

[KoBeWi]

Tested versions

4.3 dev2
4.3 5034478
Works correctly in 4.2.1

System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

Issue description

I had some script errors due to deleted scripts, so I deleted script cache, but my project could no longer run. So I decided to delete the whole .godot folder and I can't open the project anymore. The RAM usage skyrockets to over 8GB and then either editor dies or the system freezes and then editor dies.

There is nothing useful in the output, even in verbose mode.

Steps to reproduce

1. Open my project in Godot 4.3.
2. Wait until it loads.
3. 💀

Minimal reproduction project (MRP)

I can share the project privately.
It does not happen in a minimal one and I don't know which part causes the problem.

What if you open it in a new self-contained instance of the editor? Sounds like another deadlock though.

PS. If it's a deadlock, you can manually pause the debugger pretty much at any point and it's likely to stop around the code that is locked.

[KoBeWi]

Seems like it worked in a self-contained mode 🤔
Which probably means that the bug can't be reproduced reliably even with the same project 🙄

inb4 it's EditorResourcePreview deadlocking while trying to generate a preview for GDScripts with unresolved class names or circular deps..

I think we should get rid of GDScript previews, or at least of the highlighting part that requires loading/parsing.

[KoBeWi]

I used debugger to see what is it doing in the background and seems like it's loading random scenes across the project.
It's not stuck on a single one, but the memory usage steadily increases.

EDIT:
Seems like it hangs when loading TileSet, idk.

[KoBeWi]

Apparently the culprit is 958699a
After removing these two lines

godot/editor/editor_file_system.cpp

Lines 1687 to 1688 in da945ce

	_get_all_scenes(get_filesystem(), update_scene_paths);
	_update_scene_groups();

the project opens normally. It's only a problem if group cache does not exist.

I found more info and I was right that it's related to TileSet.

First, the reason why it hangs itself in the first place: when you load a TileSet, it does a call_deferred() to _update_padded_texture. Since the scene is freed after scanning, the TileSet is loaded for every scene and queues the texture update every time (even if the object that waits for the update is gone...). Scene scanning happens in a single frame, so the queue is never flushed, which means that after enough scenes are loaded, the TileSet updates will clog it up, which causes queue error to print and calls statistics() function.

I assume what happens next is that statistics() tries to access the already deleted resource and goes here:

godot/core/object/message_queue.cpp

Lines 464 to 469 in da945ce

	if (null_target) {
	//object was deleted
	print_line("Object was deleted while awaiting a callback");
	null_count++;
	}

And print_line() is deferred :D Which means that it will try to use already full queue and recursively call the same function until everything dies.

There are 2 separate solutions to apply here:

• don't do deferred call when loading TileSet (idk how it can be avoided)
• remove print_line() from statistics() to avoid recursively destroying the message queue

Also since group scanning is so long, it should use EditorProgress and possibly happen over a few frames, to avoid clogging message queue.

EDIT:
Another thing I just realized is that TileSet will do _update_padded_texture() for every single tile...

remove print_line() from statistics() to avoid recursively destroying the message queue

This was done elsewhere, so makes sense here too, will open a PR for that

#89493 prevents TileSet from exploding memory usage and #89490 prevents crashing if it still happens for some reason, so this issue is resolved (the project can be opened).

Remaining problems mentioned here:

• TileSet filling call queue while being loaded repeatedly. This is only specific to group loading (and possibly other scene mass-load code). Normally the TileSet is used after being loaded, so it's fine like this if it's not easily fixable
• Global group caching takes loooooooong time and the editor is unresponsive at that time. I'll open a separate issue. This only affects projects that are very big and don't have cache yet EDIT: Caching scene groups can take a long time while the editor is unresponsive #89516
