Merge pull request #304 from isislovecruft/fix/remove-rand_os 
Remove dev-dependency on deprecated rand_os crate.

Remove dev-dependency on deprecated rand_os crate. 
The functionality we were using is now contained in the `rand_core` crate, which
we already depend upon.  As far as testing code goes, only benchmarks still
depend upon `rand`, as they use `thread_rng`.

Change all from_slice() constructors to return Option<T>s. 
We due this in lieu of implementing `TryFrom` to allow for API
consumers to use the `?` operator to convert potential `None`s into
their own `Result<T, CustomError>` types for better error handling
with less boilerplate.

Note that this is a breaking API change.

Remove test for validity of randomly generated RistrettoPoints. 
This test is no longer necessary as it originally had a possibility of
failure due to the original implementation of the invsqrt() function
in the decompression algorithm.  The failure with the current API is
nonexistent.

* FIXES #288.

6739399ec2 Upgrade to current rand_core, rand, rand_os. 
Of these only `rand_core` is included in the public API; regardless of `rand`
semver tricks, this is a breaking API change, but the major version is already
bumped to include the Serde serialization fixes.

018fccfe8c Avoid over-specific version specifiers. 
By default, Cargo treats version specifiers as semver-compatible ranges, so the
version specifiers we include should only have the components that are actually
meaningful, e.g., "1" instead of "1.0.0" (which actually means "1").

9480844b8d Switch from clear_on_drop to zeroize (fixes #281) 
`zeroize` is WASM-friendly as it has no dependencies on C compilers.

Instead uses Rust's own volatile write semantics and compiler fences to
ensure zeroization is not elided by the compiler.

70e46c9826 Fill in missing Serde impl for MontgomeryPoint. 2019-10-23 15:55:03 -07:00
Henry de Valence
0fc534d989 Use "tuples" instead of "bytes" in the Serde datamodel. 
This is a breaking change to the serialization format.  It fixes it so that the
Serde encoding can match the conventional encoding of each type of object, and
so that Serde can be used with no overhead -- when using serde-bincode, the
Serde encoding now matches the manual encoding.
 2019-10-23 15:40:50 -07:00
Henry de Valence
29ce0d4fe9 Add length checks to serde-bincode tests. 
This ensures that the serde Serialize and Deserialize implementations use
fixed-length Serde tuples, rather than variable-length byte arrays.  This flaw
in data modeling was pointed out by Trevor Perrin.

574217694e Remove build.rs. 
This was more useful at the time when we were determining, e.g., optimal lookup
table sizes and could regenerate them more easily, but it came at a massive
complexity cost.  It also meant that we were unable to implement backend
autoselection.  This commit removes the `build.rs` entirely.  In the future, a
different `build.rs` could be added that auto-selects a backend, but it seems
like the current default-u64 setup has been working fine.

Rust fixes for some clippy warnings 
Clippy lints with instances in the project but NOT applied here, since they seem consistently at odds with the projects' style:

- [cast lossless](https://rust-lang.github.io/rust-clippy/master/#cast_lossless)
