Add dust note detection to change selection.
...
The change selection algorithm has the most useful information for
determining whether or not a note is dust, so this adds a new error case
to `ChangeError` that allows the change selection to report the presence
of input notes without economic value back to its caller.
2022-11-10 12:18:30 -07:00
9a7dc0db84
Add traits for fee estimation and input selection
...
This adds a set of abstractions that allow wallets to provide
independent strategies for fee estimation and note selection, and
implementations of these strategies that perform these operations in the
same fashion as the existing `spend` and `shield_transparent_funds`
functions.
This required a somewhat hefty rework of the error handling in
zcash_client_backend. It fixes an issue with the error types whereby
callees needed to have a bit too much information about the error
types produced by their callers.
Reflect the updated note selection and error handling in zcash_client_sqlite.

Add fee calculator to the transaction builder.
...
This adds a fee calculation strategy abstraction that can be used to
dynamically compute fees so that the total fees required may be taken
taken into account during note selection, and also removes automatic
change creation from the transaction builder.
Change outputs must now be directly created by the caller by the caller.
This is a necessary prerequisite for permitting fees to adjust based
upon the contents of the transaction being constructed.
The initial implementation of the fee strategy simply uses the current
default fee.

Require a source transparent address to shield transparent funds.
...
Previously, `shield_transparent_funds` was only shielding funds
associated with the legacy default transparent address. This meant
that transparent funds sent to unified addresses could not reliably
be shielded, as a unified address will frequently be constructed
using a diversifier index greater than zero.
This modifies the `get_transparent_receivers` method to return address
metadata containing the account ID and diversifier index used to derive
each address along with the receiver.

an error if the caller attempts to use them in a wallet that has not
been configured with support for transparent inputs functionality.

Remove `received_by_account` field from WalletTransparentOutput
...
Due to how the wallets retrieved unspent transparent outputs from the
light wallet server, the account associated with a particular UTXO may
not be known by the light wallet. Instead of requiring the caller to
perform a separate lookup and match the address of the received UTXO
with a known account, it's simpler to perform this lookup internally at
the time of insertion or update.
In order to make this operation more efficient, the `addresses_table`
migration is modified to add a column to cache the transparent receiver
so that it may be used in the joins in the UTXO insert and update
operations.

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

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.

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.

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.

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`.

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.

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.

zcash_client_backend: Use correct output index for t-addr recipients
...
`create_spend_to_address` was originally written only for sending to
Sapling addresses. It was later amended to support sending to
transparent addresses, but the assumption about there being a Sapling
output was not removed. This was not an issue for most transactions
because there would be change, but in the case of a z->t transaction
with no change, `create_spend_to_address` would reliably panic.
This commit fixes the bug by setting the output index for transparent
recipients to 0. The `output_index` field of `SentTransaction` is also
documented to correctly reflect its dependency on the type of
`recipient_address`.

Update changelogs with Memo changes
2021-03-18 10:00:27 +13:00
8a84203685
Remove Default impl from MemoBytes
...
Memo fields have two ways to encode an empty memo:
- 0xF6 followed by all-zeroes, encoding "there is no memo".
- All-zeroes, encoding the empty UTF-8 string.
In almost all cases you want the former, but users thinking about byte
slices may expect MemoBytes::default() to result in the latter. To
ensure clarity, we now require calling either MemoBytes::default() or
MemoBytes::from_bytes(&[]) to be explicit.
No such confusion exists for the Memo enum, because the two types are
visibly separated as different enum cases, and Memo::Empty makes sense
as the default.
2021-03-17 21:16:01 +13:00
c7a3ef0e88
Split memo-handling into MemoBytes struct and Memo enum
...
The MemoBytes struct is a minimal wrapper around the memo bytes, and only
imposes the existence of null-padding for shorter memos. The only error
case is attempting to construct a memo that is too long. MemoBytes is
guaranteed to be round-trip encodable (modulo null padding).
The Memo enum implements the additional memo rules defined in ZIP 302,
interpreting the contents of a memo (for example, parsing it as text).
