Kris Nuttycombe e3aafdad19 Move chain continuity checks into `scan_block_with_runner` 
In preparation for out-of-order range-based scanning, it is necessary
to ensure that the size of the Sapling note commitment tree is carried
along through the scan process and that stored blocks are always
persisted with the updated note commitment tree size.

Kris Nuttycombe 0a4236f725 zcash_client_sqlite: Add tests for sqlite-backed ShardTree & fix revealed issues. 2023-06-29 15:35:18 -06:00
Kris Nuttycombe 3e358bc1c9 zcash_client_backend: Use `shardtree` for note commitments in block scanning. 
Also adds a skeleton `zcash_client_sqlite` implementation of
`shardtree::ShardStore` and a skeleton migration for related
database changes.

Kris Nuttycombe 980736806f Upgrade `incrementalmerkletree` & `orchard` patch versions. 2023-05-25 12:33:25 -06:00
Jack Grigg 2ae4d87cbf zcash_primitives: Remove redundant checks from Sapling note decryption 
- The consistency check between `esk` and `ephemeral_key` is checked
  inside `zcash_note_encryption::try_output_recovery_with_ock`.
- The `diversifier` validity check is necessarily performed when
  deriving `pk_d` for the `ivk` pathway, so we keep it there for the
  `ovk` pathway as well, and drop the check from the `PaymentAddress`
  internal constructor.

Jack Grigg 26d95b4a0e zcash_primitives: Temporarily expose v5 Sapling bundle parsing 
This is currently exposed via `Transaction` for usage in `zcashd`, but
may be removed in future (if `zcashd` moves transaction parsing entirely
into Rust), or renamed and stabilised.

Kris Nuttycombe 71f74d4ac1 Remove the `merkle_tree::incremental` module.

incremental witnesses in the `merkle_tree` module.

Kris Nuttycombe 1f9747e15f Move merkle tree types to the `incrementalmerkletree` crate. 
This removes the `CommitmentTree`, `IncrementalWitness`, and
`MerklePath` types in favor of equivalent versions available
from the `incrementalmerkletree` crate.

Kris Nuttycombe ec57d23115 Use const generics to set commitment tree & incremental witness depths. 
This is in preparation for extraction into the `incrementalmerkletree`
crate, which is not Sapling-specific and therefore cannot hard-code
the depths of these data structures.
