Fix WorldScape editor shutdown crash by dominicbytes · Pull Request #1400 · Redot-Engine/redot-engine

dominicbytes · 2026-09-07T05:25:44Z

Move WorldScape cleanup to NOTIFICATION_PREDELETE, while child pointers are valid. Free detached dialogs and unparented asset controls synchronously.

Validation: standalone Windows build; resource lifetime tests, Node/Control tests (23 total), and three headless shutdown checks pass. No new GUI retest.

Run: python tests/editor/test_shutdown.py <editor>.

Summary by CodeRabbit

Bug Fixes
- Improved WorldScape 3D editor shutdown cleanup by releasing UI components synchronously.
- Prevented editor resources, dialogs, asset entries, and textures from lingering during cleanup.
Tests
- Added automated coverage for editor shutdown behavior across multiple runtime durations.
- Added checks confirming WorldScape 3D editor resources are released correctly in and out of the scene tree.

Walkthrough

WorldScape3D editor components replace deferred child-node cleanup with synchronous deletion during predelete handling. New tests verify resource release and headless editor shutdown at multiple frame counts.

Changes

WorldScape3D shutdown cleanup

Layer / File(s)	Summary
Menu dialog cleanup `modules/worldscape_3d/editor/menu.`, `modules/worldscape_3d/editor/menu/`	Menu and dialog classes move owned-control cleanup from destructors and `queue_free()` to `NOTIFICATION_PREDELETE` handlers or `memdelete()`.
Editor UI cleanup `modules/worldscape_3d/editor/ui/*`, `modules/worldscape_3d/editor/worldscape_3d_editor.cpp`	Asset dock, tool settings, editor UI, and editor plugin cleanup paths synchronously delete owned controls, dialogs, and timers.
Shutdown and resource validation `modules/worldscape_3d/tests/test_editor_cleanup.h`, `tests/editor/test_shutdown.py`	Tests verify synchronous resource release and headless shutdown for 10, 120, and 600 frames.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 01d46

The shutdown cleanup change can leave the WorldScape3D tool-settings panel unrendered or improperly laid out because its container notification handling is bypassed. Restore the base notification call before merging.

I never reproduced this crash?

This occurred for me just a little bit ago while testing the other 4 PR's.

If you can manually (as in, manually launching the editor) reproduce this in the master branch, open an issue detailing the circumstances under which the crash occurs and link it to this PR.

Up until yesterday, I could consistently launch the master branch, add a WS3D node and close the editor with the process always returning error code 0. No leaked resource warnings either.

dominicbytes · 2026-09-07T18:52:06Z

@OldDev78 Clarification: this was found during automated headless testing. Manual GUI closing has not been reproduced here.

Rebuilt unmodified master at a7e798c (clean checkout). Windows 10 Pro 22H2 x64, build 19045.7417; MSVC 14.51.36231; Python 3.11 / SCons 4.10.1:

python -m SCons platform=windows target=editor arch=x86_64 debug_symbols=yes -j24

Create repro/project.godot containing only:

config_version=5
[application]
config/name="Shutdown reproduction"

Then run in PowerShell:

& .\bin\redot.windows.editor.x86_64.exe --headless --editor --path .\repro --quit-after 10 --max-fps 60
$LASTEXITCODE

Master crashes on shutdown with 0xC0000005 (3221225477). Reproduced at 10, 120, and 600 frames, then repeated with a fresh self-contained editor profile: 6/6 crashes, each using a fresh project. No scene, script, or WS3D node is needed.

Matching stack from master:

Node::queue_free (scene/main/node.cpp:3478)
ChannelPackerDialog::`scalar deleting destructor'
Node::_notification (scene/main/node.cpp:304)
WorldScape3DMenu::_notification_backwardv (modules/worldscape_3d/editor/menu.h:46)
predelete_handler (core/object/object.cpp:2353)
SceneTree::_flush_delete_queue (scene/main/scene_tree.cpp:1610)
SceneTree::finalize (scene/main/scene_tree.cpp:862)

The original test binary at 7d4d64c also crashes 3/3. This PR's build at 01d462e exits 0 with empty stderr for all three frame counts (built with tests=yes additionally).
