Jack Grigg 789e2ff216 Travis CI: Build before formatting check 
cargo fmt does not build the code, and running it in a fresh clone of
the codebase will fail because the protobuf code has not been generated.

Jack Grigg 2bafc688ff Test nullifiers in constant time 
Checking for spent notes in a block is still not completely constant
time, due to filtering out negative results of the constant-time
comparison.

Part of #84.
 2019-08-22 12:52:01 +01:00
Jack Grigg 2774d2730f Add prevHash field to CompactBlock

Jack Grigg 7c07914bfd Separate Amount::{from_i64, from_nonnegative_i64} APIs 
This is more intuitive than a boolean flag for handling non-negative
Amounts stored in i64 values.

Jack Grigg 79006ecbdf Unify Sapling tree depth constants 
When sapling-crypto is refactored, the zcash_primitives::sapling
constant would become the canonical one.

Jack Grigg e67560b154 Document merkle_tree module 2019-07-10 13:53:22 -04:00
Jack Grigg b9cea33804 Move merkle_tree::Node into sapling module 
This makes the merkle_tree module properly generic over the tree hash.
It still hard-codes a depth 32 tree, because Rust doesn't yet support
generic sizes, and we are unlikely to need to alter the tree depth in
future circuit changes.

Jack Grigg d1ce6749fe Bump minimum Rust version to 1.36 2019-07-10 13:12:26 -04:00
Jack Grigg 999dcbfcab Migrate to blake2b_simd and blake2s_simd crates 
The primary reason for migrating is that these crates provide APIs for
setting the personalisation string. This enables us to depend solely on
published crates, and thus publish our own crates.

The SIMD implementations are ported from libsodium.

Closes #67.
