BZLZHH 4532cae175 [Feat] (MG_Impl, MG_Util): STENCIL_INDEX8 renderbuffers; report distinct D/S renderbuffers unsupported 
GL_STENCIL_INDEX8 becomes a first-class internal format (VK_FORMAT_S8_UINT
backing, metrics, classifiers, converters), so glRenderbufferStorage
accepts it instead of leaving GL_INVALID_ENUM behind. Framebuffer
completeness now also mirrors the renderer's gate for renderbuffers:
distinct depth/stencil renderbuffer attachments (or a renderbuffer
paired with a texture) report GL_FRAMEBUFFER_UNSUPPORTED - the spec only
requires the same-image case - instead of passing completeness and then
failing at draw/clear (verify_mixed_attachments.* now passes).

BZLZHH 282dd69230 [Feat] (DirectVulkan, MG_Impl): depth-stencil ReadPixels and combined-attachment queries 
glReadPixels now serves GL_DEPTH_COMPONENT, GL_DEPTH_STENCIL and
GL_STENCIL_INDEX from the read framebuffer's depth/stencil attachment:
per-aspect vkCmdCopyImageToBuffer copies (4-byte-aligned stencil region)
with CPU repacking into GL_FLOAT / GL_UNSIGNED_SHORT / GL_UNSIGNED_INT /
GL_UNSIGNED_INT_24_8 / GL_FLOAT_32_UNSIGNED_INT_24_8_REV /
GL_UNSIGNED_BYTE layouts, honoring pack state and pixel-pack buffers.

GL_DEPTH_STENCIL_ATTACHMENT parameter queries follow the spec's combined
rules: differing depth/stencil attachment images (or a lone half) fail
with GL_INVALID_OPERATION, as does GL_FRAMEBUFFER_ATTACHMENT_COMPONENT_TYPE
on the combined name. packed_depth_stencil.verify_parameters.* and
verify_read_pixels.depth24_stencil8 now pass.

BZLZHH 47dd8cdc05 [Feat] (MG_Impl): answer format-derived framebuffer attachment queries 
glGetFramebufferAttachmentParameteriv (and the DSA variant) now answer
GL_FRAMEBUFFER_ATTACHMENT_RED/GREEN/BLUE/ALPHA/DEPTH/STENCIL_SIZE,
COMPONENT_TYPE and COLOR_ENCODING from the attached image's internal
format, and accept the default-framebuffer attachment names (GL_DEPTH,
GL_STENCIL, GL_FRONT/GL_BACK variants). Querying them with no image
attached reports GL_INVALID_OPERATION per spec instead of
GL_INVALID_ENUM.

swung0x48 b8a8a660e1 [Refactor] (Lifecycle): own MobileGL's lifecycle from the EGL layer instead of ELF static ctor/dtor - the first EGL/WGL entry point lazily initializes via a thread-safe, re-init-capable EnsureInitialized (AutoInit is gone), the last eglTerminate with no initialized display and nothing current tears the whole library down deterministically inside the EGL lifecycle, and the global singletons move to leak-at-exit heap storage so process exit runs no backend destructors at all (AutoDestroy and the Windows DllMain abandon hook are gone); fixes the exit-time SIGABRT from undefined static-destruction order - the DirectGLES buffer-pool mutex abort on Android clean exits, and the pre-existing macOS QueryTest/ProgramTest 'Subprocess aborted' gtest failures now pass (ctest 411/411) 2026-07-26 10:59:14 -04:00
swung0x48 c30bd0fabb [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl): draw/read-buffer state could land on the wrong FBO (glDrawBuffer's static-array latch; SyncToBackend emitting glDrawBuffers/glReadBuffer for the non-bound target; no resync on bound-FBO attachment/drawbuffer edits) leaving MC 26.3's OIT color clears as no-ops; apply per bound target and track the FBO object version 2026-07-17 11:45:54 -04:00
swung0x48 5cd82f2002 Merge origin/dev (efd7b473) into readback overhaul - unify DirectGLES 2D-array target support under MapToBackendTextureTarget, keep canonical UNorm8 shadows for RGBA4/RGB565 (supersedes packed-word transfer types; GL_RGB565 aliases RGB5), keep upstream GLSL 330 normalization, anisotropy params, error-count semantics and VK clear/scissor fixes 2026-07-16 23:17:37 -04:00
swung0x48 870d882fef [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl, MG_Util): GL CTS packed_pixels + texture_swizzle readback overhaul - canonical shadow layouts for legacy sized/unsized/packed internal formats (RGB5->RGB565, RGB10/12->RGB16, RGBA2->RGBA4, RGB10_A2(UI)/RGB9_E5/R11F_G11F_B10F packed-word shadows with per-texel encode/decode incl. 5_9_9_9_REV and 10F_11F_11F_REV client types), GL_UNSIGNED_INT_10_10_10_2 pixel type mapping, conversion-first GetTexImage with CPU-shadow fallback for non-attachable formats and stale-temp-FBO detach, narrow implementation read pairs + SNORM read candidates + 2_10_10_10_REV wide-read decode with RGBA expansion, PACK image/skip and SWAP_BYTES honored on the CPU repack (never in ES), state-reset conformance (default-texture TexParameter/TexImage/TexBuffer no-ops, renderbuffer 0 unbind, vertex attrib 0 current value, ActiveTexture up to combined units, UBO binding count clamp), FramebufferTexture3D/TextureLayer slice attachments via glFramebufferTextureLayer, capability-driven FBO UNSUPPORTED for non-renderable colors, ReadPixels integer-ness mismatch error, single-value texture swizzle validation, and DirectGLES 1D/1D-array/2D-array texture emulation (2D/2D-array backend targets matching SPIRV-Cross ES 1D-as-2D shaders) 2026-07-16 22:41:54 -04:00
swung0x48 a08669df72 [Fix] (MG_Impl/GLImpl): stop recording GL errors on the delete/query paths of every object family - glDeleteBuffers/VertexArrays/Renderbuffers/Framebuffers must silently ignore unknown names and glIsTexture must never raise, while glBindSampler now reports INVALID_OPERATION like the other bind entry points 2026-07-16 22:11:43 -04:00
swung0x48 a1a8a18575 [Fix] (MG_Backend/DirectGLES, MG_Impl/GLImpl): ReadPixels - fall back to wide-format conversion when the ES driver rejects a legacy native read combo (Adreno errors on e.g. GL_RED/GL_UNSIGNED_INT and leaves the buffer untouched), and enforce packed-type/format pairing at the state layer via shared ValidateClientFormatTypePairing (GL_RED + GL_UNSIGNED_SHORT_5_6_5 now raises GL_INVALID_OPERATION) 2026-07-16 06:11:53 -04:00

swung0x48 cf165c0db5 [Fix] (MG_Backend/DirectVulkan): support Voxy rendering 
Implemented:

- Advertise Voxy-required DirectVulkan extensions without raising the reported OpenGL version.

- Add DirectVulkan compute, indirect draw count, DSA, readback, and buffer state paths needed by Voxy.

Fixed:

- Enable Vulkan shaderInt64 and drawIndirectFirstInstance so Voxy baseInstance-driven LOD draws address the correct section data.

- Fix DirectVulkan synchronization, framebuffer, texture readback, and shader interface handling used by Voxy and Minecraft screenshots.

Tests:

- Add MG_Test coverage for DirectVulkan extension advertising, DSA buffer/texture/framebuffer/vertex-array behavior, persistent mapped readback, and shader/program paths.
