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.

Removes errors that are not used anymore

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
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.

[#534] Use UnifiedSpendingKey for shielding and Spending
This commit implements the use of Unified Spending Keys for shielding
and spending as well as rolling Unified Addresses.
Users should obtain addresses by rolling them from the SDK.

when shielding or spending
Closes#534

* Fix rebase issues
* PR Suggestion. Make `lastError` an Optional
* Fix test `testReOrgRemovesOutboundTxAndIsNeverMined`

this introduces several types under UnifiedAddress `ReceiverTypecodes`
and `UnifiedAddress.Errors` to host possible errors on third-party
generated UAs and their composition
Implement extracting the typecodes from a UA
This PR creates data types for Addresses and Keys so that they are
not represented by Strings anymore. This avoids mistakenly use
the wrong keys because they are all alike for the type system.
New Protocols:
=============
StringEncoded -> Protocol that makes a type can be expressed in an
string-encoded fashion either for UI or Interchange purposes.
Undescribable -> A protocol that implements methods that override default
decriptions used by debuggers, loggers and event trackers to avoid types
conforming to it to be leaked to logs.
Deleted Protocols:
==================
UnifiedFullViewingKey --> turned into a struct.
UnifiedAddress --> turned into a struct
new Error Type:
================
````
enum KeyEncodingError: Error {
case invalidEncoding
}
````
This error is thrown when an Address or Key type (addresses are public
keys in the end) can be decoded from their String representation,
typically upon initialization from a User input.
New Types:
=========
SaplingExtendedSpendingKey -> Type for Sapling Extended Full Viewing Keys
this type will be replaced with Unified Spending Keys soon.
SaplingExtendedFullViewingKey -> Extended Full Viewing Key for Sapling.
Maintains existing funcionality. Will be probably deprecated in favor of
UFVK.
TransparentAccountPrivKey -> Private key for transparent account. Used
only for shielding operations. Note: this will probably be deprecated soon.
UnifiedFullViewingKey -> Replaces the protocol that had the same name.
TransparentAddress -> Replaces a type alias with a struct
SaplingAddress --> Represents a Sapling receiver address. Comonly called zAddress. This address corresponds to the Zcash Sapling shielded pool.
Although this it is fully functional, we encourage developers to
choose `UnifiedAddress` before Sapling or Transparent ones.
UnifiedAddress -> Represents a UA. String-encodable and Equatable. Use of
UAs must be favored instead of individual receivers for different pools.
This type can't be decomposed into their Receiver types yet.
Recipient -> This represents all valid receiver types to be used as
inputs for outgoing transactions.
````
public enum Recipient: Equatable, StringEncoded {
case transparent(TransparentAddress)
case sapling(SaplingAddress)
case unified(UnifiedAddress)
````
The wrapped concrete receiver is a valid receiver type.
Deleted Type Aliases:
=====================
The following aliases were deleted and turned into types
````
public typealias TransparentAddress = String
public typealias SaplingShieldedAddress = String
````
Changes to Derivation Tool
==========================
DerivationTool has been changed to accomodate this new types and
remove Strings whenever possible.
Changes to Synchronizer and CompactBlockProcessor
=================================================
Accordingly these to components have been modified to accept the
new types intead of strings when possible.
Changes to Demo App
===================
The demo App has been patch to compile and work with the new types.
Developers must consider that the use (and abuse) of forced_try and
forced unwrapping is a "license" that maintainers are using for the
sake of brevity. We consider that clients of this SDK do know how to
handle Errors and Optional and it is not the objective of the demo
code to show good practices on those matters.
Closes#461
This also brings in various associated changes to the FFI methods in
zcash-light-client-kit as a result of moving to the main branch of
zcash/librustzcash.
This commit makes Renames `WalletBirthday` to `Checkpoint` and
makes Checkpoint an internal type. Public ocurrences of this
type is replaced by `BlockHeight` (Int) and then retrieval of the
Checkpoint is deferred to the appropiate place in the code
Add an extension method to `BlockHeight` to get latest checkpoint
height present in the SDK's bundle
PR Suggestions:
Add test for integer overflow on JSON
File renamed from WalletBirthday to Checkpoint
* [#397] Checkpoint format that supports NU5 TreeStates
Closes#397
This commit adds `orchardTree` value to WalletBirthday and renames
the value `tree` to `saplingTree`. It also modifies the checkpoint
JSON files accordingly. It adds `.testnet` and `.mainnet` checkpoints
for orchard activation height.
* rename `sapling-checkpoints` to `checkpoints`
Closes#401
This commit changes the way Codable in implemented for Zatoshi and PendingTransaction.
SQLite attempts to decode Custom Types as JSONStrings inside a TEXT column whereas Zatoshi only needs to be an INTEGER that can be treated as an Int64 value
`ConfirmedTransaction` entity is not affected because it is already deserialized
in a custom fashion whereas `PendingTransaction` was relying on `Codable` and
`CodingKey`.
Closes#381
This commit brings a Zatoshi type developed on the Secant project,
helper classes like Clamped and tests.
Zatoshi has been incorporated as a Codable type for SQLite Swift
to allow serialization into the pending database.
