Closes#888.
- `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.
Closes#801
- `SDKSynchronizer.wipe()` can be now called anytime.
- If the sync is in progress then the sync is first stopped and then
wipe is executed.
- Wipe now returns AnyPublisher which completes or fails when wipe is
done.
- Majority of wipe's work is to delete files. That is only operation
that can throw error during wipe. This operation should succeed every
time. If it fails that something is seriously wrong. When this happens
the SDK can happen in inconsistent state. There is no recovery for
now. Only way how to fix this is to reinstall the app in the device.
- Added hooks mechanism. This is implemented in `AfterSyncHooksManager`
and it is used by `CompactBlockProcessor`. It's just more organized
way how to track what should happen when the sync process is canceled.
Closes#778
- .swiftlint.yml is now used to lint only the code of the SDK.
- .swiftlint_tests.yml is now used to lint only the code of the tests.
This config disables rules that were previously disabled in the code
in lot of tests.
