This change switches to a new (future) version of the rust crates
that will get rid of the sent and received transactions Views in
favor of a `v_transaction` view that will do better accounting of
outgoing and incoming funds. Additionally it will support an
outputs view for seeing the inner details of transactions enabling
the SDKs tell the users the precise movement of value that a tx
causes in its multiple possible ways according to the protocol.
the `v_tx_outputs` view is not yet implemented.
Sent and Received transaction sub-types are kept for compatibility
purposes but they are generated from Overviews instead of queried
from a specific view.
In the transaction Overview the value represents the whole value
transfer for the transaction from the point of view of a given
account including fees. This means that the value for a single
transaction Overview struct represents the addition or subtraction
of ZEC value to the account's balance.
Future updates will give clients the possibility to drill into the
inner workings of those value changes in a per-output basis for
each transaction.
Also, the field `pending_unmined` field was added to `v_transactions`
so that wallets can query `DataDb` for pending but yet unmined txs
This will prepare the field for removing the notion of a "PendingDb"
and its nuances.
Also updated test database `darkside_data.db`

- `ZcashRustBackend` is actor now. So majority of methods in this actor
are now async.
- Some methods stayed `static` in `ZcashRustBackend`. It would be hard
to pass instance of the `ZcashRustBackend` to the places where these
methods are used in static manner. And it would change lot of APIs.
But it isn't problem from technical perspective because these methods
would be `nonisolated` otherwise.
- Methods `lastError()` and `getLastError()` in `ZcashRustBackend` are
now private. This makes sure that ther won't be aby race condition
between other methods and these two error methods.
- All the methods for which was `lastError()` used in code now throw
error. So `lastError()` is no longer needed outside of the
`ZcashRustBackend`.
- There are in the public API related to `DerivationTool`.
- `DerivationTool` now requires instance of the `ZcashRustBackend`. And
`ZcashRustBackend` isn't public type. So `DerivationTool` doesn't have
any public constructor now. It can be created only via
`Initializer.makeDerivationTool()` instance method.
- `deriveUnifiedSpendingKey()` and `deriveUnifiedFullViewingKey()` in
`DerivationTool` are now async. It is because these are using
`ZcashRustBackend` inside. `DerivationTool` offers alternative
(closure and combine) APIs. But downside is that there is no sync API
to dervie spending key or viewing key.
- Some methods of the `DerivationTool` are now static. These methods
don't use anything that requires instance of the `DerivationTool`
inside.
[#888] Use Sourcery to generate mocks
- I wrote mock for `Synchronizer` manually. And it's tedious and long
and boring work.
- Now `ZcashRustBackendWelding` is changed a lot so it means
`MockRustBackend` must be changed a lot. So I decided to introduce
`sourcery` to generate mocks from protocols so we don't have to do it
manually ever.
- To generate mocks go to `ZcashLightClientKit/Tests/TestUtils/Sourcery`
directory and run `generateMocks.sh` script.
- Your protocol must be mentioned in `AutoMockable.swift` file.
Generated mocks are in `AutoMockable.generated.swift` file.
[#888] Fix Offline tests
- Offline tests target now runs and tests are green.
- There is log of changes in tests. But logic is not changed.
- Updated `AutoMockable.stencil` so sourcery is able to generate mock as
actor when protocol is marked with: `// sourcery: mockActor`.
- Last few updates in `ZcashRustBackendWelding`. In previous PR `rewindCacheToHeight`
methods was overlooked and it didn't throw error.
- Removed `MockRustBackend` and using generated
`ZCashRustBackendWeldingMock` instead.
- Using generated `SynchronizerMock`.
[#888] Fix NetworkTests
- Changed a bit how rust backend mock is used in the tests. Introduced
`RustBackendMockHelper`. There are some state variables that must be
preserved within one instance of the mock. This helper does exactly
this. It keeps this state variables in the memory and helping mock to
work as expected.
[#888] Fix Darkside tests
Create ZcashKeyDeriving internal protocol
Use New DerivationTool that does not require RustBackend
Remove duplicated methods that had been copied over
[#888] Fix potentially broken tests
I broke the tests because I moved `testTempDirectory` from each
`TestCase` to the `Environment`. By this I caused that each tests uses
exactly same URL. Which is directly against purpose of
`testTempDirectory`.
So now each test calls this one and store it to local variable. So each
test has unique URL.
[#888] Add ability to mock nonisolated methods to AutoMockable.stencil
[#888] Add changelog and fix the documentation in ZcashRustBackendWelding
[#888] Rename derivation rust backend protocol and remove static methods
- Renamed `ZcashKeyDeriving` to `ZcashKeyDerivationBackendWelding`. So
the naming scheme is same as for `ZcashRustBackendWelding`.
- `ZcashKeyDerivationBackend` is now struct instead of enum.
- Methods in `ZcashKeyDerivationBackendWelding` (except one) are no
longer static. Because of this the respective methods in
`DerivationTool` aren't also static anymore.
