- This is the first change for the dependency injection. This change
adds `DIContainer` which is used to register and resolve dependencies.
- Then this change shows how `DIContainer` can be used to resolve
dependencies. And it also shows how to mock dependencies in tests.
- Constructors of `Initializer` are changed to support mocking of
depedendencies. But it doesn't affect public API in any way.
- Depedencies are registered in `Dependencies.setup()`. Then in the code
`container.resolve(SomeType.self)` is called to get instance of the
dependency.
- `ZcashTestCase` class is added. It inherits from `XCTestCase` and
should be used for base class in tests. `ZcashTestCase` takes care of
creation of `DIContainer` for dependencies mocking. In future we can
maybe move there more things that are used in each test.
- Lot is missing here. Not all the code is using dependency injection.
Tests for `DIContainer` are missing. Only `OfflineTests` work now
(other tests can't be even compiled). It will be added in future
changes.
`lastError` inside the `BlockDownloaderImpl` was set even when
downloading task was canceled. And because it was canceled the
`lastError` has never been read by CBP before the next sync. And when
next sync was started it was immediately failed because of cancelation
error stored in `lastError`.
Changes the way unpadded bytes are turned into a UTF-8 Swift String
without using cString assuming APIs that would overflow memory and
add garbled trailing bytes.

Removes `PendingTransactionEntity` and all of its related components.
Pending items are still tracked and visualized by the existing APIs
but they are retrieved from the `TransactionRepository` instead by
returning `ZcashTransaction.Overview` instead.
`pendingDbURL` is removed from every place it was required. Its
deletion is responsibility of wallet developers.
`ClearedTransactions` are now just `transactions`.
`MigrationManager` is deleted. Now all migrations are in charge of
the rust welding layer.
`PendingTransactionDao.swift` is removed.
Implementation of `AccountEntity` called `Account` is now `DbAccount`
`ZcashTransaction.Overview` can be checked for "pending-ness" by calling
`.isPending(latestHeight:)` latest height must be provided so that minedHeight
can be compared with the lastest and the `defaultStaleTolerance` constant.
`TransactionRecipient` is now a public type.
protocol `PendingTransactionRepository` is removed.
`TransactionManagerError` and `PersistentTransactionManager` are deleted.
`OutboundTransactionManager` is deleted and replaced by `TransactionEncoder`
which now incorporates `submit(encoded:)` functionality
`WalletTransactionEncoder` now uses a `LightWalletService` to submit the
encoded transactions.

fix warnings
- `BlockDownloaderImpl` is changed. It now spawns detached Task to
download blocks. So blocks can be downloaded in parallel with scanning
process.
- `Synchronizer.stop()` is no longer async.
- Blocks cache cleaning is changed. It's not possible to drop the whole
cache now. There are some blocks pre-downloaded which weren't scanned
yet.
It looks like that some methods in `ZcashKeyDerivationBackendWelding`
were left async by mistake. There is no reason for any method there to
be async.
After this change no method in `DerivationTool` has to async. It makes
things much easier.
This PR introduces `ZcashError` enum. This enum represents any error
that can be thrown inside of the SDK and outside of the SDK. Also
`ZcashError` is used in `LightWalletGRPCService` and handled in
`CompactBlockProcessor` as example.
Why enum? First I tried this with some structure which contained code,
message and underlyingError. Problem was when some specific place in the
SDK would like to attach some additional data to error. I didn't want to
add some generic dictionary to store anything with the error.
So I used enum to identify error. Each member can have specified amount
of associated values. So specific error can bring some context data. And
it's type safe.
Each error has also a code. Relationship between errors and codes is
1:1. It may looks bit redundant but it's important. The client app now
can choose how to process errors. Either identify those by the error
itself or by code.
Definition or errors and codes is in `ZcashErrorDefinition`. And then
`ZcashError` and `ZcashErrorCode` are generated by Sourcery. Thanks to
this it is easier to maintain the final code. And it gives us ability to
generate any kind of documentation for the errors and codes. I created
simple example of this in this PR. And it doesn't make the SDK
completely dependent on the Sourcery. Final structures aren't super
complicated and can be written manually if needed.

Use let instead of var where applicable
In the SDK `var` was used on places where `let` would be sufficient. And
default strategy in Swift should use use `let` until mutability is
required. So all these places are changed. No logic is changed.

Make DerivationTool constructor public
DerivationTool.init should be public. This was removed by accident when
adopting async.
[#361] Add changelog
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`
Closes#959Closes#971 ZcashLightClientKitSample main target broken swiftlint script
Demo App improvements: Show Short date and value on transaction list
- attached to the processor's timer
- added latest scanned time and latest block height
- sample app showing the new values alongside with the %
- unit tests fixed
- latestBlock() API added
- the transaction repository is no longer used to update the exposed values during the syncing
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#895
Add Sync Session ID to `SynchronizerState`.
A SyncSession is an attempt to sync the blockchain within the lifetime of a Synchronizer.
A Synchronizer can sync many times, when synced it will refresh every ~20 seconds +- random padding.
each sync attempt will have a different UUID even if it's from the same instance of SDKSynchronizer.
**How are SyncSessions are delimited? With `SyncStatus` changes.**
changes from [`.unprepared`|`.error`|`.disconnected`|`.stopped`] to `.syncing` assign a new sessionID to the synchronizer.
Any other transitions won't.
`areTwoStatusesDifferent ` was refactored to a helper function of `SyncStatus`
**How are IDs generated?**
ID generation is not mandated but delegated to a protocol `SyncSessionIDGenerator`.
Tests inject their own deterministic generator to avoid test flakiness.
Default implementation of SyncSessionIDGenerator is
````Swift
struct UniqueSyncSessionIDGenerator {}
extension UniqueSyncSessionIDGenerator: SyncSessionIDGenerator {
func nextID() -> UUID {
UUID()
}
}
````
**SyncSession Pseudo-Atomicity and thread safety**
SyncSession is a type alias of a GenericActor holding a UUID
````
typealias SyncSession = GenericActor<UUID>
extension SyncSession {
/// updates the current sync session to a new value with the given generator
/// - Parameters generator: a `SyncSessionIDGenerator`
/// - returns: the `UUID` of the newly updated value.
@discardableResult
func newSession(with generator: SyncSessionIDGenerator) async -> UUID {
return await self.update(generator.nextID())
}
}
````
