Kris Nuttycombe 56b2edd498 Simplify sqlite backend storage for sent notes & utxos.
The currently deprecated implementations of `insert_sent_utxo`,
`insert_sent_note`, `put_sent_utxo` and `put_sent_note` all store to the
same `sent_notes` table internally. Since there's no immediate plan to
change this arrangement, it's better to have a single pair of internal
`insert_sent_output` and `put_sent_output` methods instead.

Jack Grigg 913aa0a988 zcash_client_backend: Correctly track heap usage of batch items
As of zcash/librustzcash#633, `SaplingDomain::IncomingViewingKey` now
allocates memory internally, and this memory persists as long as the
`BatchRunner` is alive. Now that we have decoupled the measurement of
heap usage for batch tasks from their internals, we can add bounds to
all of the generic parameters of `Batch` to enable correctly measuring
their actual heap usage.

We also add `DynamicUsage` impls for a bunch of `zcash_primitives` types
that will be used with `BatchRunner` (or its equivalent implementation
in `zcashd`) by callers.
2022-09-24 21:01:19 +00:00
Jack Grigg c98f04330d zcash_client_backend: Move heap tracking of batch tasks behind a trait
This enables the heap usage measurements to be conditionally enabled by
the `BatchRunner` user. Importantly, when heap usage measurements are
not enabled, the `DynamicUsage` bound on `Batch` is not required.

This refactor also fixes a bug in the prior implementation. We were
counting the heap usage of a task when it started to run, but the item
may have been in the `rayon` work-stealing queues for a non-negligible
period before then. We now count the heap usage immediately before
spawning the task into the `rayon` thread pool.

Jack Grigg fe258ca120 zcash_client_backend: Count `tags` in `impl DynamicUsage for Batch` 2022-09-24 13:06:04 +00:00
Jack Grigg 9a1d61cb4e zcash_client_backend: Only store successes in batch scanner
Previously we were sending an `Option<DecryptedNote>` from each `Batch`
back to its parent `BatchRunner`. However, this requires allocating
sufficient space in the channel to handle the case where every output
can be decrypted. In general this will not be the case, and we can
instead signal "nothing decrypted" by just dropping the channel sender.
This reduces the post-batch-scanning memory usage of `BatchRunner` from
being linear in the number of on-chain outputs, to being linear in the
number of outputs for the wallet.

Ported from zcash/zcash@f7f6c2070d.

Jack Grigg 8f03208439 zcash_client_backend: Add tags to IVKs in the batch scanner
This removes the dependency on `SaplingIvk::to_repr()`, and enables us
to alter the type of `D::IncomingViewingKey` to improve the performance
of batch scanning.

For the welding rig, we already annotate the viewing keys with
`AccountId`, so we use `(AccountId, Scope)` as the tag.

Kris Nuttycombe 03b0ff7e0a Replace `get_address` with `get_current_address` and `get_next_available_address`
This updates the data access API to provide diversified address
functionality. In order to support this change, the addresses table
is updated to store diversifier index information in big-endian order
to allow sorting by diversifier index, and account initialization
is updated to store the diversifier index accordingly. The currently
unreleased `addresses_table` migration is updated to reflect this
change.

Jack Grigg 4f5d757883 zcash_client_backend: Change to `WalletWrite::remove_unmined_tx`
This fixes a bug in the logic ported from the Android SDK: it was
possible to remove a transaction in the middle of a chain, which would
cause a long-spent note to become unspent and cause the wallet balance
to be over-counted. We now restrict transaction removal to unmined
transactions, which is sufficient for the Android SDK use cases.
2022-08-30 22:54:58 +00:00
Jack Grigg 586b7e5bb0 zcash_client_backend: Add `WalletWrite::remove_tx` method
This is to replace the database mutations in the Android SDK. It is

is suitable as a general-purpose API (or replace it).

Jack Grigg b52e949bd6 zcash_client_backend: Migrate to correct ZIP 316 UFVK encoding
We also add support for parsing Orchard full viewing keys from encoded
UFVKs (rather than treating them as unknown). `UnifiedSpendingKey` still
does not have Orchard support, so `UnifiedFullViewingKey`s will be
generated without Orchard components.

Jack Grigg 76d015ed11 zcash_client_backend: Fix `UnifiedFullViewingKey` Sapling item type
Per ZIP 316, the Sapling FVK Encoding only includes `(ak, nk, ovk, dk)`
which is a subset of the Sapling `ExtendedFullViewingKey`. We therefore
need to use `DiversifiableFullViewingKey` inside `UnifiedFullViewingKey`
in order to make it parseable from the UFVK string encoding.

`zcash_client_sqlite::wallet::get_extended_full_viewing_keys` has been
removed as a consequence of this change: we can no longer reconstruct
the correct `ExtendedFullViewingKey` from the `UnifiedFullViewingKey`.

Jack Grigg d8b860207d zcash_client_backend: Remove account from `UnifiedFullViewingKey`
The account number is not stored in the ZIP 316 UFVK encoding, and in
general won't necessarily be known (e.g. if a UFVK is being imported
into a wallet).

`zcash_client_sqlite::wallet::init::init_accounts_table` reverts to its
previous behaviour of requiring the provided `&[UnifiedFullViewingKey]`
to be indexed by account number.

Jack Grigg e86ba927af zcash_client_backend: Add a fake UFVK encoding
We can't use the real ZIP 316 encoding until `UnifiedFullViewingKey` has
been altered to not store a Sapling `ExtendedFullViewingKey`. But making
that change first requires fully migrating `zcash_client_sqlite` in the
same commit (as its entire API is built around `ExtendedFullViewingKey`).

Instead, we define a temporary fake encoding, to enable migrating the
`zcash_client_sqlite` APIs more incrementally.

`protobuf 2.26.0` bumped its MSRV to 1.52.1, which is incompatible with
our current MSRV.

Kris Nuttycombe a1e693d15f Remove the Wif type; it should not be used.
We should attempt to avoid passing spending keys back and forth
across the FFI entirely, but in any case this is no longer the
correct type to use at this boundary; we should use the encoding
of the transparent component of a unified spending key instead.

This updates UnifiedFullViewingKey to conform to ZIP 316, and
adds types that facilitate this support. These types should likely
be factored out from `zcash_client_backend` into `zcash_primitives`
along with the remainder of the existing unified address support.

Kris Nuttycombe 1373221439 Renames the `ExtendedFullViewingKey::address` method to `find_address`.
This also adds a new semantically different `address` method which
attempts to produce an address given the specified diversifier index,
and returns `None` if that index does not produce a valid diversifier.

It is then up to the caller to search the diversifier index space if
the diversifier index that they are attempting to use does not result in
a valid diversifier.

Jack Grigg 83c6a2d1ca Store OutputDescription `ephemeral_key` as bytes
This removes an unnecessary `to_bytes` during trial decryption of notes,
and more closely matches the protocol spec. We retain the consensus rule
canonicity check on epk due to `SaplingVerificationContext::check_output`
taking a `jubjub::ExtendedPoint`, forcing `zcashd` to parse the bytes.
