Henry de Valence 1fc859d0c5 chain: move Spend, Output into sapling
The ShieldedData container for the spend and output descriptions of a
transaction does *not* move, because it's encoding transaction
structure.  A good sign that this is the right factoring is that the
transaction module now only needs to pull in sapling::{Spend, Output}
and not all the internals.

Henry de Valence 61dea90e2f chain: rename BlockHeaderHash to block::Hash
This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.

Henry de Valence ce1e81b274 chain: move merkle_tree to block::merkle.
This Merkle tree is the SHA256d one used only for including transactions
in a block, so it should be kept there in order to not be confused with
other Merkle trees (like the note commitment trees).

Henry de Valence 196e841cd9 chain: rename LightClientRootHash to RootHash
It's not accurate to call it a LightClientRootHash, because it's not
always a root has for a light client -- sometimes it's a different kind
of root hash.

Henry de Valence b296d1e2a3 chain: move Block into a leaf module.
This might make things a little easier to rearrange.  In the future it
would probably be good to change to block::Hash, block::Header, etc.

Henry de Valence 948b067808 chain: move Network, NetworkUpgrade to parameters
Also, avoid using star-imports of the enum variants, which pollutes the
namespace.
2020-08-17 11:46:34 -07:00
Henry de Valence 64d9d55992 chain: organize block tests
This moves the tests::generate module into the block tests.  Because
this whole set of changes is just focused on reorganization, the
generate code is unchanged, but in the future, the code should be
rewritten as a collection of proptest strategies.
2020-08-17 11:46:34 -07:00
Henry de Valence 855b89dec4 chain: create a new work module for proof-of-work
This extracts the `difficulty` module from `block` and the
`equihash_solution` module from the crate root.  The PoW calculations
are significantly more complicated than the other block code and pretty
dissimilar from it, so it makes more sense to create a common proof of
work module.

The `EquihashSolution` and `EQUIHASH_SOLUTION_SIZE` are renamed to
`equihash::Solution` and `equihash::SOLUTION_SIZE` and imported that
way, except in `block/header.rs`, to avoid a conflict with the
`equihash` crate.  In the future it would be better to encapsulate the
equihash solution check into the `equihash::Solution` type so that
callers only need to import our `work::equihash`.

The test organization leaves a little to be desired but I think that
this can be improved as we fill out the proof of work implementation.

Henry de Valence 8e9a239687 chain: clean transaction tests module.
This moves the transaction strategies to `arbitrary`, to live with the
other strategy impls (`Arbitrary` is just a default type-associated
strategy), splits the proptests into a new `prop` module, and splits the
test vector checks into a `vector`s module.

This ensures that we keep code in leaf modules and only have
organization (use statements) in non-leaf modules.

Henry de Valence a35604aef3 chain: move amount to a top-level module. 2020-08-17 11:46:34 -07:00
Henry de Valence cee7d0b8eb chain: move serde_helpers into serialization. 2020-08-17 11:46:34 -07:00
Henry de Valence b36fe8f937 chain: move sha256d to serialization module.
This extracts the SHA256d code from being split across two modules and puts it
in one module, under serialization.

The code is unchanged except for three deleted tests:

* `sha256d_flush` in `sha256d_writer` (not a meaningful test);
* `transactionhash_debug` (constructs an invalid transaction hash, and the
  behavior is tested in the next test);
* `decode_state_debug` (we do not need to test the Debug output of
  DecodeState);
2020-08-17 11:46:34 -07:00
Henry de Valence 9f31e551c9 chain: split serialization.rs into files
The code is unchanged except for removing an unneeded clippy annotation in proptests.rs.
2020-08-17 11:46:34 -07:00
Henry de Valence 0d1f56ad2f chain: remove utils module
A catch-all utils module can really easily slip into being a place to stash
miscellaneous functions that don't really belong anywhere in particular.
