What

  • relicense cuda-bindings and the cuda-python metapackage under Apache 2.0
  • make the root LICENSE canonical and package Apache 2.0 license copies in all independently built distributions while preserving package-specific copyright spans
  • set License-Expression metadata and package the canonical license in wheels and sdists
  • convert generated and maintained source headers without functional generated-code changes
  • remove the remaining proprietary EULA text and enable cuda-bindings contributions through the DCO workflow

Dependency

This draft is based on the post-PR-2285 main branch and is blocked on the internal cybind MR.

Validation

  • clean modern and legacy generation for CTK 13.3 and 12.9 emitted Apache-2.0 for all 68 CUDA outputs while preserving the proprietary default for unrelated outputs
  • cuda-python and cuda-bindings wheels and sdists report License-Expression: Apache-2.0 and License-File: LICENSE with exact canonical license bytes
  • local/path-based cuda-bindings lockfile entries report Apache-2.0 while historical released-package entries retain their original metadata
  • CUDA 13.3 bindings wheel built successfully
  • 378 bindings tests passed with 64 expected skips
  • 9 Cython interoperability tests passed
  • bindings documentation built successfully
  • all repository pre-commit hooks passed

We should update the latest copyright year on any file we've relicensed. The copyright year checker missed some -- possibly because you didn't have the changes statged when it ran (see #2293 and #2273).

Also I think the start copyright year for cuda-pathfinder was updated inadvertently.

I'm not sure why the copyright year updater didn't catch this one, but we should probably update all the years on the files this touches.

Retroactive? I don't think cuda-pathfinder existed in 2024.

codex found this:

Tracked lockfiles still contain old cuda-bindings license metadata, e.g. cuda_bindings/pixi.lock:3035 and cuda_core/pixi.lock:4497. They are excluded from SPDX checks and partly describe old solved/released packages, but they will still show up in repo-wide old-license searches.

I raised issue #2298 after seeing this.

Not sure if we want to do anything about it, but I thought it's useful to document clearly what we have at the moment.
