OpenXR CTS 1.1.42.0 (2024-11-07)

This release, like the previous one, has a separate “Usage Guide” document with instructions and command lines, instead of a complex README. See the previous release notes for more info. There is one known issue in this release, but it only affects the self-tests (not required for conformance) under OpenGL. Passing exclude:[self_test] when running interactive tests with OpenGL will work around the issue. A fix is known and in review, expected by next release. - Conformance Tests - Fix: Update generated code to allow - in interaction profile paths. (internal MR 3493) - Fix: Allow interaction profiles which do not expose boolean paths to be tested. (internal MR 3506) - Fix: Include interaction profile dependencies in generated binding path dependencies. (internal MR 3507, internal issue 2350) - Fix: Correctly parse and process interaction profile path and binding path dependencies from XML, and clean up code in interaction_profile_processor.py. (internal MR 3507, internal MR 3521) - Fix: Add missing XML description of EXT_hand_interaction additions to several interaction profiles, affecting generated interaction profile tests. (internal MR 3517, internal MR 3541, internal MR 3544) - Fix: remove unused functionPtr field in global FunctionInfoMap as it is invalid if called with a different instance. (internal MR 3547) - Fix: Correct an outdated description of the self tests in the Usage document: glTF files now load asynchronously in those tests. (internal MR 3553) - Fix: Internal cross-references in the “Submission Package” section of the Usage document. (internal MR 3562) - Improvement: Update stb_image from 2.27 to 2.30 (latest upstream) for fixes, security improvements, and optimizations. (internal MR 2578) - Improvement: Update stb_typetype to latest upstream for float comparison fixes. (internal MR 2578) - Improvement: Update Catch2 from v3.3.2 to v3.7.1, including our custom fork of the jUnit reporter. Provides build-time and runtime performance improvements, among other changes. (internal MR 2893) - Improvement: Reorganize session state tests and use test sections, annotating assertions with spec links. (internal MR 3017, internal MR 3468) - Improvement: Update tinygltf to version 2.9.3. (internal MR 3366) - Improvement: List failed test cases, and unmatched test specs, at end of CTS run. (internal MR 3489) - Improvement: Add warnings if supporting OpenXR 1.1 but not supporting optional, but recommended, extensions providing compatibility for OpenXR 1.0 apps/engines. (internal MR 3499) - Improvement: Make generated interaction profile sources reproducible/deterministic. (internal MR 3507) - Improvement: Correct the build-time dependencies of the generated interaction profile data. (internal MR 3521) - Improvement: Note in the Usage document that /interaction_profiles/ext/hand_interaction_ext and /interaction_profiles/ext/eye_gaze_interaction are generic interaction profiles that should be tested if supported. (internal MR 3524, internal MR 3506) - Improvement: Added support for PRIMARY_STEREO_WITH_FOVEATED_INSET in xrLocateViews tests. (internal MR 3527, internal MR 3571) - Improvement: Add command lines for Android for the self tests in the Usage document. (internal MR 3553) - New test: Show a perceptively-smooth gradient in two swapchain formats or two layer types (projection vs quad), to do basic rendering verification. This primarily catches issues where non-linear textures are being interpreted as linear or vice-versa in a runtime’s compositor. (internal MR 3351, internal issue 2239) - New test: Check xrCreateInstance patterns required by API layers. (internal MR 3415, internal issue 2333, OpenXR-CTS PR 94) - New test: Verify behavior when session state related calls occur out of order. (internal MR 3468, internal MR 3579) - New test: When using XR_FB_space_warp, verify runtime returns XR_ERROR_VALIDATION_FAILURE if nearZ is equal to farZ (internal MR 3523) - New test: Add additional assertions for xrGetInputSourceLocalizedName, after removing incorrect portions of the test.
