* [#1108] Instrument rust backend tracing
This adds a parameter to the `Initializer` constructor that allows
developers to turn on performance trancing tooling on the Rust
backend. It can't be disabled on the fly. It's either OFF or ON
all the life-span for the Synchronizer.
Closes#1108
Update ffi framework commit hash
* update resolved filed
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#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`.
- 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#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.
