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#795
- Added structure `SaplingParamsSourceURL` which holds source URLs for
sapling-spend file and sapling-output file. URLs are ultimately passed
to `SaplingParameterDownloader`.
- This is done so it's possible to pass different URLs when running
tests.
- sapling-spend file and sapling-output file are in tests bundle. And
when running tests these files are loaded from bundle and not from
network.
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.
Closes#743
- Added new protocol `BlockValidator` and `BlockValidatorImpl` class. All the code related to blocks validation is extracted to `BlockValidatorImpl`.
- Fixed `testSingleDownloadAndScan()` test.
- Changed how validation error are handled. Previously validation error were handled directly next to validation code. And when some validation
errors happened method from `CompactBlockProcessor` were called. Now validation errors are handled in `CompactBlockProcessor.processNewBlocks`
in a same way as any other error that can occur during sync process.

- [#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`.
- Fix all the tests. In few tests code had to be changes because order
of transactions is newly defined. It wasn't before.
- Change properties of Transaction.* objects. Some had to be made
Optional to make all tests work.
- Add new tests for TransactionDAO.
- Removed methods from TransactionDAO that weren't used.
Our main dependency, Swift-GRPC is dropping support for Cocoapods from version 1.8.2.
Even though they make a great work at maintaining backwards compatibility, we will eventually be forced to drop Cocoapods support.
We've reached out partners like NighthawkApps, Horizontal Systems (Unstoppable) and Edge, who have reported not depending on Cocoapods.
We intend to end Cocoapods support on 0.18.0.
Closes#612
- Removed `Transaction` struct and `TransactionEntity` protocol.
- Removed some other protocols from `TransactionEntity.swift`.
Use correct default fee and memo count
This is small improvement of lives for developers. Before this change if
developer wanted to test if change can be compiled then developer had to
go scheme by scheme and test compilation. This change introduces `All`
scheme which builds all the targets on one key stroke/mouse click.
- SDKMetrics singleton for the measurement
- download, validate and scan blocks supported
- Sample app refactored to use SDKMetrics, connected to appropriate notifications and labels
- enhancement metric added
- total sync time metric added
- sample app extended to show summary time and operations summaries
- unit tests for the SDKMetrics
- doc for the SDKMetrics and our approach for the performance testing in general
- changelog update
Closes#677
- Previously when keychain wanted to do wipe wallet had to do it on it's
own. Which isn't good. Now wallet can simply call
`synchronizer.wipe()` and it's done.
- This change brings support for wipe. `Synchronizer` has new method
`wipe()` which takes care of everything. All the database connections
are closed. Databases are removed. `InternalSyncProgress` is reset.
Change condition when wipe can run
Closes#657
- Now SDK downloads N downloads and scan those. And repeat until sync is
done. This safes lot of space of disk used to store downloaded blocks.
- Most changes are done in `CompactBlockProcessor.processNewBlocks`.
- `SyncRanges` structure is changed a bit.
- `SyncStatus` is changed. SDK now report that it's syncing with
progress. It doesn't report each phase of the sync process separately.
Also appropriate notifications were updated.
Address review comments
- Small changes
- Add tests to check computation of processing ranges for single loop
- Previously we had one range for each sync which was used for each
phase of sync process. Newly there is separate range for each phase of
the sync process.
- I added `InternalSyncProgress` utility. This utility tracks progress
of some phases. And it is able to compute right ranges which should be
used for syncing.
- Some unused download code from `CompactBlockProcessor` is removed.
Fix tests
Address review comments
- Rebase to master
- Update how range for `processBatchFinished()` is computed.
- Refactor `InternalSyncProgress`
- Add tests for `InternalSyncProgress`
Address review comments
Change how latest downloaded block is tracked
- Cache DB is no longer used to track which block was downloaded as
latest. `InternalSyncProgress` is used to do that.
- Thanks to that #660 is fixed. And cache DB can be completely removed
after sync process.
- Added sleep(1) to some darkside tests when latest block height is set.
Otherwise lightwalletd in darkside mode doesn't have time to setup and
tests are flaky.
Fix TransactionEnhancementTests.testBasicEnhancement test
- sync process enhanced to try to download sapling params if needed
- tests fixed
- failing import Crypto -> import CryptoKit
- download params only if there are sapling funds
Closes#616
- Added small helper `NotificationSender` which is used to send
notifications.
- No notificaiton is sent on main thread.
- Change how `status` is stored and update in `SDKSynchronizer`. It is
now protected by lock. Before this wasn't needed because status was
updated from main thread everywhere.
- `SyncBlocksViewController` in the sample app now uses
`SDKSynchronizer` instead of `CompactBlockProcessor` directly.
Closes#619
- When computing next action in `NextStateHelper.nextStateAsync` now
scanning state is also taken into consideration.
- When processing blocks download phase is skipped when it's detected
that everything is already downloaded.
