From eb762ace84107346da98546c9da754d3bc2de881 Mon Sep 17 00:00:00 2001 From: Octi Zhang Date: Fri, 1 May 2026 11:12:14 -0700 Subject: [PATCH 1/2] Skip local-only fabric notice perf regression test The CI guard in test_disabled_fabric_change_notifies_speedup_regression was an os.getenv("CI", ...) check, but this project's CI selects tests via the isaacsim_ci pytest marker (pyproject.toml) and never sets the CI env var, so the test ran on CI despite being intended for local-only verification. The wall-clock comparison is platform-sensitive and was prone to flaking. Replace the dead env-var branch with a top-level @pytest.mark.skip decorator so the test is collected and skipped unconditionally; its correctness counterpart (test_disabled_fabric_change_notifies_toggles_ ifabricusd_flag) still runs. Re-enable manually when touching the listener suspension path. --- source/isaaclab_physx/test/sim/test_cloner.py | 12 ++++++++---- 1 file changed, 8 insertions(+), 4 deletions(-) diff --git a/source/isaaclab_physx/test/sim/test_cloner.py b/source/isaaclab_physx/test/sim/test_cloner.py index b0dfaf3e081c..4bfba07d99e8 100644 --- a/source/isaaclab_physx/test/sim/test_cloner.py +++ b/source/isaaclab_physx/test/sim/test_cloner.py @@ -552,10 +552,17 @@ def test_disabled_fabric_change_notifies_toggles_ifabricusd_flag(sim): assert bindings.is_enabled(fabric_id), "outer exit should restore the flag" +@pytest.mark.skip( + reason=( + "Local-only perf regression; correctness is covered by" + " test_disabled_fabric_change_notifies_toggles_ifabricusd_flag." + " Re-enable manually when touching listener suspension." + ) +) def test_disabled_fabric_change_notifies_speedup_regression(): """Local-only perf regression: listener suspension speeds up clone+reset by >= 1.2x. - Skipped under ``CI=true`` — the suspension mechanism's correctness is covered by + Skipped unconditionally — the suspension mechanism's correctness is covered by :func:`test_disabled_fabric_change_notifies_toggles_ifabricusd_flag`; the wall-clock win is platform-sensitive (deferred Fabric resync in ``sim.reset`` can offset the scene-time savings on some hardware).

Nudge the eye to (0.001, 0, 5) for both the ray caster and USD camera so the look direction is no longer parallel to up, while keeping the two cameras at identical poses. The underlying degeneracy is tracked in a separate internal ticket; this is the test-side mitigation. --- source/isaaclab/test/sensors/test_ray_caster_camera.py | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/source/isaaclab/test/sensors/test_ray_caster_camera.py b/source/isaaclab/test/sensors/test_ray_caster_camera.py index cc10b092a806..a913d38dd833 100644 --- a/source/isaaclab/test/sensors/test_ray_caster_camera.py +++ b/source/isaaclab/test/sensors/test_ray_caster_camera.py @@ -898,11 +898,11 @@ def test_output_equal_to_usd_camera_when_intrinsics_set(setup_sim, focal_length_ # set camera position camera_warp.set_world_poses_from_view( - eyes=torch.tensor([[0.0, 0.0, 5.0]], device=camera_warp.device), + eyes=torch.tensor([[0.001, 0.0, 5.0]], device=camera_warp.device), targets=torch.tensor([[0.0, 0.0, 0.0]], device=camera_warp.device), ) camera_usd.set_world_poses_from_view( - eyes=torch.tensor([[0.0, 0.0, 5.0]], device=camera_usd.device), + eyes=torch.tensor([[0.001, 0.0, 5.0]], device=camera_usd.device), targets=torch.tensor([[0.0, 0.0, 0.0]], device=camera_usd.device), )
