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.
Closes#764
- All notification that were previously sent from CompactBlockProcessor are now gone.
- `CompactBlockProcessor` now provides `eventStream` to communicate with `SDKSynchronizer`.
- Added `synchronizerStoredUTXOs` notification.
- Tests are updated to not use notifications anymore. Some tests there
weren't working before are now fixed.
- Added `CompactBlockProcessorEventHandler` utility class. Previously
expectations were subscribing to notifications. This class replaces
this functionality. It subscribes to events from
`CompactBlockProcessor` and fullfill expectations.
Closes#746
- `LightWalletGRPCService` is no longer public. `LightWalletService` is no longer public.
- `LightWalletGRPCService` shouldn't be used dicrectly. Use `LightWalletServiceFactory` to create instance of the service.
- Moved sending of `blockProcessorConnectivityStateChanged` notification to `Initilizer`.
- All the errors from GRPC are mapped to `LightWalletServiceError`. Handling of `GRPCStatus` in the SDK is no longer required.
- `Service` directory (that contains GRPC code) is moved to `Modules/Service`. We can put more code to `Modules/` if we decide
to modularize more code.

- [#790] Fix ShieldFundsTests
Closes#790
Removes comments on `ShieldFundsTests` since those issues have been fixed
Depends on zcash-light-client-ffi changes that adopt newer versions of
librustzcash crates `zcash_primitives 0.10`, `zcash_client_backend 0.7`,
`zcash_proofs 0.10`, `zcash_client_sqlite 0.5.0`.
Also allows wallets to define a shielding_threshold and will set
foundations to customize minimum confirmations for balances, spends
and shielding operations.
**Test Bootstrapping**
- `ZcashCompactBlockDescriptor`: struct that holds functions to
describe blocks as filenames and compare those filenames
`ZcashCompactBlockDescriptor.live` has the actual implementation
but it can be replaced by mocks if needed on Tests
main implementations are held under `FSCompactBlockRepository.filenameDescription` and `FSCompactBlockRepository.filenameComparison` on a separate extention
`DirectoryListingProviders` provide two default implementations of listing a
directory deterministically. `FileManager` does not define a sorting and needs to be done in-memory by calling `.sorted()` on the resulting collection. If this
is a big toll on performance it can be changed to a POSIX implementation but
this is good for now.
`ZcashCompactBlockDescriptor` adds a `height` helper function to
turn a filename into the height of the block stored.
Implemented `func latestHeight() throws -> BlockHeight ` that
returns the blockheight by querying the cache directory in a sorted
fashion and getting the last value and turning the filename into a
`BlockHeight`
Added `Meta` struct to ZcashCompactBlock.
Tests implemented:
- `filterBlockFiles`
- `testClearTheCache`
- `testLatestHeightEmptyCacheThrows`
- `testLatestHeightEmptyCacheThrowsAsync`
- `testRewindEmptyCacheDoesNothing`
- `testRewindEmptyCacheDoesNothingAsync`
- `testWhenBlockIsStoredItFollowsTheDescribedFormat`
- `testWhenBlockIsStoredItFollowsTheFilenameConvention`
- `testGetLatestHeight`
- `testRewindDeletesTheRightBlocks` test
- `testPerformanceExample` test. This isn't a real performance test because the API doesn't work with async/await yet
adopts `shield_funds` shielding threshold parameter
Implements `initBlockMetadataDb` and fix tests
Renames dbCache parameter to `fsBlockDbRoot`. Builds but tests don't pass.
Removes cacheDb uses from code. Testing utilities still persist.
Added needed information in MIGRATING and CHANGELOG.
Added helper to perform deletion of legacy db and creation a the
new file system backed cache.
Renames parameters and changes code where needed.
Network Constants turned into `enum` with static methods.
DeletelastDownloadedBlock helper from initializer
Removes CompactBlockStorage and CompactBlockEntity.
Implements `latestCachedBlockHeight` on rustbackend.
*Replaces dependencies on ZcashRustWelding with `FSMetadataStore`*
This allows the tests to not depend in a particular implementation
of either the MockRustBackend of or ZcashRustBackend. Also provides
a way to test errors properly and switch implementations of critical
areas like `writeBlocks`.
