Modified GDScript code gets saved to disk without a prompt

[Rubonnek]

Godot version:
master branch commit eaa5dfb

Steps to reproduce:

1. Save all the changes to a scene.
2. Open a GDScript with the built-in editor and write some text to it and do not save those changes.
3. Go to Scene->Quit to exit the editor, and click on Quit.
4. The GDScript that was being modified gets saved to disk

I've also noticed that when editing a GDScript that was just saved, it is not getting marked as modified in the editor as soon as you start typing.

Minimal reproduction project:
saved_without_asking.zip

I do not know the system of the reported issue but I can confirm this on Ubuntu in master and 3.0.2 too.

I got a similar issue, and I'm able to trigger it by doing this:

• Modify a GDScript
• Instead to save the file Press F5 to start the game

Now even if the editor show saving process the file was not saved and it became impossible to save. The only way to make it saving again is Close then Open the editor.

Maybe script text editor is applying (saving to disk) changes on exit?

Apparently this is just a feature of the editor and can be enabled/disabled with the interface/editor/save_each_scene_on_quit property. So this isn't a bug and can probably be closed?

EDIT: Don't mind that, it still saves with that property disabled :/

Still reproducible in the current master branch.

This one's nasty! Combined with #40199 I think the only way to safely discard bad changes to a script is to forcibly kill the Godot process.

[Calinou]

This is likely due to the script editor remembering script state across sessions. Can someone try to reproduce this on the latest master branch?

I could reproduce it on master branch with the same steps.
