[dependabot]

Bumps naga from 29.0.4 to 30.0.1.

Release notes

Sourced from naga's releases.

v30.0.1

Bug Fixes

Vulkan

• Stop passing an un-waited fence to vkAcquireNextImageKHR on non-Windows platforms, which triggered VUID-vkAcquireNextImageKHR-fence-10066 validation errors every frame since v30.0.0. By @​ErichDonGubler in #9855.

Metal

• Resolve metal color space constants dynamically. By @​andyleiserson in #9819.

WebGPU

• Upgrade vendored WebGPU bindings and wasm-bindgen to 0.2.127. This fixes a panic “can't access property "info", arg0 is null” when using the WebGPU backend and requestAdapter() fails. By @​beicause in #10034, backported in #10105.

v30.0.0

Major changes

Optional vertex buffer slots

This allows gaps in VertexState's buffers and adds support for unbinding vertex buffers, bringing us in compliance with the WebGPU spec. As a result of this, VertexState's buffers field now has type of &[Option<VertexBufferLayout>]. To migrate, wrap vertex buffer layouts in Some:

  let vertex_state = wgpu::VertexState {
      module: &vs_module,
      entry_point: Some("vs_main"),
      compilation_options: wgpu::PipelineCompilationOptions::default(),
      buffers: &[
-         &vertex_buffer_layout
+         Some(&vertex_buffer_layout)
      ],
  };

By @​teoxoy in #9351.

Integer shader I/O no longer defaults to @interpolate(flat)

To align with the shading language specifications, naga no longer assumes that integer-typed shader I/O should have flat interpolation, i.e., should not be interpolated. Even though flat interpolation is the only choice for integer I/O, it must be still specified explicitly.

WGSL:

 struct FragmentInput {
     @location(0) tex_coord: vec2<f32>,
-    @location(1) index: i32,
+    @location(1) @interpolate(flat) index: i32,
 }

Antigravity review (Gemini via Ultra)

This PR bumps the naga dev-dependency in crates/rusty2600-frontend/Cargo.toml from 29 to 30 and updates Cargo.lock to pull naga 30.0.1.

Blocking issues

• Test validation version mismatch causes false-positive shader verification: As documented in crates/rusty2600-frontend/Cargo.toml and test harnesses such as crates/rusty2600-frontend/src/gfx.rs, naga is explicitly required to match the exact version used by wgpu at runtime so shader errors fail CI rather than aborting the application. In Cargo.lock, runtime dependencies (wgpu-core, wgpu-hal, etc.) remain on naga 29.0.4. Upgrading the dev-dependency to naga 30.0.1 invalidates this correctness contract: WGSL syntax or capabilities valid in Naga 30 could pass CI tests but fail or abort at runtime under Naga 29.

Suggestions

• Reject or close this PR until wgpu can be updated to version 30 in tandem across the workspace (a bump previously deferred because egui-wgpu 0.35 still pins wgpu 29, as recorded in CHANGELOG.md).
• Add an ignore rule in your automated dependency management configuration (e.g., Dependabot) for naga so it is not updated independently of wgpu.

Nitpicks

• The PR title contains duplicated scope tokens (chore(deps)(deps):); conventional commits expect a single scope (chore(deps):).

[doublegate]

Bot Review Adjudication (Antigravity + CodeRabbit):

• Addressed Antigravity's blocking finding: naga 30.0.1 is upgraded in lockstep with wgpu 30.0.1 (and grouped in .github/dependabot.yml) in the consolidated dependency PR so offline WGSL shader validation in tests matches the runtime wgpu shader compiler.

Superseded by consolidated dependency PR #49.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
