76e0f658c1 Rename CommitmentTreeWitness -> MerklePath 2020-02-08 00:36:40 +00:00
Jack Grigg
3a3008caf9 Pass CommitmentTreeWitness directly into Builder::add_sapling_spend 
This is more likely to be the data that the caller has available, and
is all we need now that a CommitmentTreeWitness can compute its root.

2064d1c801 Refactor zcash_primitives::merkle_tree::CommitmentTreeWitness 
- The internal Option wrapper was an unnecessary leftover from when this
  code was directly inside the prover, where Some(x) represents an
  assigned variable.
- CommitmentTreeWitness::from_slice_with_depth is more idiomatic Rust.

1f38523fff CI: Use stable Rust release for code coverage 
Fixes an issue where cargo-tarpaulin failed to build the crate on
1.37.0, but the crate itself builds fine with that version.

00a4e1388b ff: Make byteorder an optional dependency under the std feature flag 
Building ff with the std feature flag was previously broken because it
required importing byteorder functionality behind the byteorder/std
feature flag. We don't use byteorder inside ff in no_std mode, so we can
just make it optional.

Constant-time field inversion in ff_derive using pow_vartime

Constant-time field inversion in ff_derive using Field::pow_vartime 
This is around 2.5-3x slower than the non-constant-time inversion. We
can regain some of this speed later by dynamically generating addition
chains.

Constant-time field inversion 
WARNING: THIS IS NOT ACTUALLY CONSTANT TIME YET!

The jubjub and bls12_381 crates will replace our constant-time usages,
but we NEED to fix ff_derive because other users will expect it to
implement the Field trait correctly.
