Clean up backend features and vendor curve25519_dalek_derive #531

pinkforest · 2023-06-13T00:08:54Z

Closes #414 (again)
Implements:

CPU auto-detection feature / cfg gate #529 consensus to use cfg(curve25519_dalek_backend = "override")
Cleans up the unused backend features which we don't want to advertise for now
Vendors in unsafe_target_feature in as curve25519-dalek-derive (co-authored by for @koute)
cfg(curve25519_dalek_diagnostics="build") now emits compile_error build diagnostics used for build script testing
Found a missing zeroize feature gate -fixed
build script is now tested with tests/build_tests.sh and added to CI
Clean up & simplify the documentation for backend override

Notes

github runner had some weird issue with incremental compilation - fixed
Closes Failed backend override - Warning or Error #532 - see: 1ac7b2 - chose compile_error to simplify gating

Do we really need a vendor/ directory?

I'd just put this in a toplevel directory called curve25519-dalek-derive, and perhaps eventually we can move the rest of the files in the toplevel directory into curve25519-dalek

yeah sure, it was already there so I thought to follow that. will move. I'll also send the workspace PR move after rc.3

Thanks so much for doing this. It's a big PR. Left a few comments about clarity here and there.

Manually verified that curve25519_dalek_derive/ mirrors the unsafe_target_feature repo at 389ae00, modulo renaming and metadata changes.

This reverts commit b87ad6b. When --cfg curve25519_dalek_backend="simd" is chosen it cannot be overriden as "serial" in build.rs and will result in both selected

Thanks for the updates! Made a pass on the README which hopefully clarifies how backend selection now works. @koute @tarcieri take a look at just the "Backend" section if you get a chance and lmk if it's good to go.

LGTM!

@pinkforest Thank you for pushing this forward!
