Unreleased

[#1019] Memo has trailing garbled text

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.

Changed

WalletTransactionEncoder now uses a LightWalletService to submit the encoded transactions.
Functions returning or receiving ZcashTransaction.Sent or ZcashTransaction.Received now will be simplified by returning ZcashTransaction.Overview or be replaced by their Overview counterparts

Added

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.

ZcashTransaction.Output can be queried to know the inner details of a ZcashTransaction.Overview. It will return an array with all the tracked outputs for that transaction so that they can be shown to users who request them
ZcashTransaction.Overview.State is introduced to represent confirmed, pending or expired states. This State is relative to the current height of the chain that is passed to the function getState(for currentHeight: BlockHeight).

State should be a transient value and it's not adviced to store it unless transactions have stale values such as confirmed or expired.

Synchronizer

public func getTransactionOutputs(transaction) async -> [ZcashTransaction.Output] is added to get the outputs related to the given transaction. You can use this to know every detail of the transaction Overview and show it in a more fine-grained UI.
TransactionRecipient is returned on getRecipients(for:).

Renamed

AccountEntity called Account is now DbAccount

Removed

ZcashTransaction.Received and ZcashTransaction.Sent are removed and replaced by Overview since the notion of Sent and received is not entirely applicable to Zcash transactions where value can be sent and received at the same time. Transactions with negative value will be considered as "sent" but that won't be enforced with a type anymore
cancelSpend(): support for cancel spend was removed since its completion was not guaranteed
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.
PendingTransactionRepository protocol is removed.
TransactionManagerError
PersistentTransactionManager
OutboundTransactionManager is deleted and replaced by TransactionEncoder which now incorporates submit(encoded:) functionality
DatabaseMigrationManager is remove since it's no longer needed all Database migrations shall be hanlded by the rust layer.
ZcashSDK.defaultPendingDbName along with any sibling members
TransactionRepository
- findMemos(for receivedTransaction: ZcashTransaction.Received)
- findMemos(for sentTransaction: ZcashTransaction.Sent)

[#1013] Enable more granular control over logging behavior

Now the SDK allows for more fine-tuning of its logging behavior. The LoggingPolicy enum provides for three options: .default(OSLogger.LogLevel) wherein the SDK will use its own logger, with the option to customize the log level by passing an OSLogger.LogLevel to the enum case. custom allows one to pass a custom Logger implementation for completely customized logging. Lastly, noLogging disables logging entirely.

To utilize this new configuration option, pass a loggingPolicy into the Initializer. If unspecified, the SDK will utilize an internal Logger implementation with an OSLogger.LogLevel of .debug

[#442] Implement parallel downloading and scanning

The SDK now parallelizes the download and scanning of blocks. If the network connection of the client device is fast enough then the scanning process doesn't have to wait for blocks to be downloaded. This makes the whole sync process faster.

Synchronizer.stop() method is not async anymore.

[#969] Clear cache on error to avoid discontinuities when verifying

This change drops the file-system cache whenever an error occurs when storing blocks so that there is not a discontinuity in the cached block range that could cause a discontinuity error on libzcashlc when calling scan_blocks. This will have a setback of at most 100 blocks that would have to be re-downloaded when resuming sync.

[#361] Redesign errors inside the SDK

Now the SDK uses only one error type - ZcashError. Each method that throws now throws only ZcashError. Each publisher (or stream) that can emit error now emitts only ZcashError.

Each symbol in ZcashError enum represents one error. Each error is used only in one place inside the SDK. Each error has assigned unique error code (ZcashErrorCode) which can be used in logs.

[#959] and [#914] Value of outbound transactions does not match user intended tx input

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.

[#888] Updates to layer between Swift and Rust

This is mostly internal change. But it also touches the public API.

KeyDeriving protocol is changed. And therefore DerivationTool is changed. deriveUnifiedSpendingKey(seed:accountIndex:) and deriveUnifiedFullViewingKey(from:) methods are now async. DerivationTool offers alternatives for these methods. Alternatives are using either closures or Combine.

[#469] ZcashRustBackendWelding to Async

This is mostly internal change. But it also touches the public API.

These methods previously returned Optional and now those methods return non-optional value and those methods can an throw error:

getSaplingAddress(accountIndex: Int) async throws -> SaplingAddress
func getUnifiedAddress(accountIndex: Int) async throws -> UnifiedAddress
func getTransparentAddress(accountIndex: Int) async throws -> TransparentAddress

These methods are now async:

func getShieldedBalance(accountIndex: Int) async throws -> Zatoshi
func getShieldedVerifiedBalance(accountIndex: Int) async throws -> Zatoshi

Initializer no longer have methods to get balance. Use SDKSynchronizer (or it's alternative APIs) to get balance.

func getSentMemoAsUTF8(dbData:idNote:networkType:) -> String? Use getSentMemo(dbData:idNote:networkType) instead

[#209] Support Initializer Aliases

Added ZcashSynchronizerAlias enum which is used to identify an instance of the SDKSynchronizer. All the paths to all resources (databases, filesystem block storage...) are updated automatically inside the SDK according to the alias. So it's safe to create multiple instances of the SDKSynchronizer. Each instance must have unique Alias. If the default alias is used then the SDK works the same as before this change was introduced.

The SDK now also checks which aliases are used and it prevents situations when two instances of the SDKSynchronizer has the same alias. Methods prepare() and wipe() do checks for used alias. And those methods fail with InitializerError.aliasAlreadyInUse if the alias is already used.

If the alias check fails in the prepare() method then the status of the SDKSynchronizer isn't switched from unprepared. These methods newly throw SynchronizerError.notPrepared error when the status is unprepared:

sendToAddress(spendingKey:zatoshi:toAddress:memo:) async throws -> PendingTransactionEntity
shieldFundsspendingKey:memo:shieldingThreshold:) async throws -> PendingTransactionEntity
latestUTXOs(address:) async throws -> [UnspentTransactionOutputEntity]
refreshUTXOs(address:from:) async throws -> RefreshedUTXOs
rewind(policy:) -> AnyPublisher<Void, Error>

Provided file URLs to resources (databases, filesystem block storage...) are now parsed inside the SDK and updated according to the alias. If some error during this happens then SDKSynchronzer.prepare() method throws InitializerError.cantUpdateURLWithAlias error.

[#831] Add support for alternative APIs

There are two new protocols (ClosureSynchronizer and CombineSynchronizer). And there are two new objects which conform to respective protocols (ClosureSDKSynchronizer and CombineSDKSynchronizer). These new objects offer alternative API for the SDKSynchronizer. Now the client app can choose which technology it wants to use to communicate with Zcash SDK and it isn't forced to use async.

These methods in the SDKSynchronizer are now async:

prepare(with:viewingKeys:walletBirthday:)
start(retry:)
stop()
cancelSpend(transaction:)
All the variants of the getMemos(for:) method.
All the variants fo the getRecipients(for:) method.
allConfirmedTransactions(from:limit:)

These properties in the SDKSynchronizer are now async:

pendingTransactions
clearedTransactions
sentTransactions
receivedTransactions

Non async SDKsynchronizer.latestHeight(result:) were moved to ClosureSDKSynchronizer.

[#724] Switch from event based notifications to state based notifications

The SDKSynchronizer no longer uses NotificationCenter to send notifications. Notifications are replaced with Combine publishers. Check the migrating document and documentation in the code to get more information.

[#826] Change how the SDK is initialized

viewingKeys and walletBirthday are removed from Initializer constuctor. These parameters moved to SDKSynchronizer.prepare function.
Constructor of the SDKSynchronizer no longer throws exception.
Any value emitted from lastState stream before SDKSynchronizer.prepare is called has latestScannedHeight set to 0.
Initializer.initialize function isn't public anymore. To initialize SDK call SDKSynchronizer.prepare instead.

[#801] Improve how wipe call can be used

SDKSynchronizer.wipe() function can be now called anytime. It returns AnyPublisher which completes or fails when the wipe is done. For more details read the documentation for this method in the code.

[#793] Send synchronizerStopped notification only when sync process stops

synchronizerStopped notification is now sent after the sync process stops. It's not sent right when stop() method is called.

[#795] Include sapling-spend file into bundle for tests

This is only an internal change and doesn't change the behavior of the SDK. Initializer's constructor has a new parameter saplingParamsSourceURL. Use SaplingParamsSourceURL.default value for this parameter.

[#764] Refactor communication between components inside th SDK

This is mostly an internal change. A consequence of this change is that all the notifications delivered via NotificationCenter with the prefix blockProcessor are now gone. If affected notifications were used in your code use notifications with the prefix synchronizer now. These notifications are defined in SDKSynchronizer.swift.

[#759] Remove Jazz-generated HTML docs

We remove these documents since they are outdated and we rely on the docs in the code itself.

[#726] Modularize GRPC layer

This is mostly internal change. LightWalletService is no longer public. If it is used in your code replace it by using SDKSynchronizer API.

File system backed block cache

File system based block cache. Compact blocks will now be stored on the file system. Caller must provide a URL pointing to the filesystem root directory where the fsBlock cache is. this directory is expected to contain a /blocks sub-directory with the blocks stored in the convened filename format {height}-{hash}-compactblock. This directory must be granted both read and write permissions.

the file system cache will have a "bookkeeping" database that the rust welding layer will use to know the state of the cache and locate the cached compact blocks. This directory can be deleted provided that the Compactblock processor or Synchronizer are not running. Upon deletion caller is responsible for initializing these objects for the cache to be created.

Implementation notes: Users of the SDK will know the path they will provide but must assume no behavior whatsoever or rely on the cached information in any way, since it is an internal state of the SDK. Maintainers might provide no support for problems related to speculative use of the file system cache. If you consider your application needs any other information than the one available through public APIs, please file the corresponding feature request.

Added

Synchronizer.shieldFunds(spendingKey:memo:shieldingThreshold) shieldingThreshold was added allowing wallets to manage their own shielding policies.

Removed

InitializerError.cacheDbMigrationFailed

Bugfixes

[#645] Default rewind after ReOrg is 20 blocks when it should be 10

This fixes an issue where the default reorg was 20 blocks rewind instead of 10. The reorg count was incremented before calling the rewind height computing function.

Use Librustzcash database views to query and represent transactions

[#556] Change data structures which represent transactions.

These data types are gone: Transaction, TransactionEntity, ConfirmedTransaction, ConfirmedTransactionEntity. And these data types were added: ZcashTransaction.Overview, ZcashTransaction.Received, ZcashTransaction.Sent.

New data structures are very similar to the old ones. Although there many breaking changes. The APIs of the SDKSynchronizer remain unchanged in their behavior. They return different data types. When adopting this change, you should check which data types are used by methods of the SDKSynchronizer in your code and change them accordingly.

New transaction structures no longer have a memo property. This responds to the fact that Zcash transactions can have either none or multiple memos. To get memos for the transaction the SDKSynchronizer has now new methods to fetch those:

func getMemos(for transaction: ZcashTransaction.Overview) throws -> [Memo],
func getMemos(for receivedTransaction: ZcashTransaction.Received) throws -> [Memo]
func getMemos(for sentTransaction: ZcashTransaction.Sent) throws -> [Memo]

CompactBlockProcessor is now internal

[#671] Make CompactBlockProcessor Internal.

The CompactBlockProcessor is no longer a public class/API. Any direct access will end up as a compiler error. Recommended way how to handle things is via SDKSynchronizer from now on. The Demo app has been updated accordingly as well.

We've changed how we download and scan blocks. Status reporting has changed.

[#657] Change how blocks are downloaded and scanned.

In previous versions, the SDK first downloaded all the blocks and then it scanned all the blocks. This approach requires a lot of disk space. The SDK now behaves differently. It downloads a batch of blocks (100 by default), scans those, and removes those blocks from the disk. And repeats this until all the blocks are processed.

SyncStatus was changed. .downloading, .validating, and .scanning symbols were removed. And the .scanning symbol was added. The removed phases of the sync process are now reported as one phase.

Notifications were also changed similarly. These notifications were removed: SDKSynchronizerDownloading, SDKSyncronizerValidating, and SDKSyncronizerScanning. And the SDKSynchronizerSyncing notification was added. The added notification replaces the removed notifications.

New Wipe Method to delete wallet information. Use with care.

[#677] Add support for wallet wipe into SDK. Add new method `Synchronizer.wipe()`.

Benchmarking APIs: A primer

[#663] Foundations for the benchmarking/performance testing in the SDK.

This change presents 2 building blocks for the future automated tests, consisting of a new SDKMetrics interface to control flow of the data in the SDK and new performance (unit) test measuring synchronization of 100 mainnet blocks.

[#646] SDK sync process resumes to previously saved block height

This change adds an internal storage test on UserDefaults that tells the SDK where sync was left off when cancelled whatever the reason for it to restart on a later attempt.

This only fixes the situation where rewinding the SDK would cause the whole database to be cleared instead and syncing to be restarted from scratch (issue [#660]).

[#532] [0.16.x-beta] Download does not stop correctly

Issue Reported:

When the synchronizer is stopped, the processor does not cancel the download correctly. Then when attempting to resume sync, the synchronizer is not on .stopped and can't be resumed

this doesn't appear to happen in master branch that uses structured concurrency for operations.

Fix: This commit makes sure that the download streamer checks cancelation before processing any block, or getting called back to report progress

[#381] Move Zatoshi and Amount Types to the SDK (#396) This deprecates many methods on SDKSynchronizer using Zatoshi for amounts instead of Int64. This exposes number formatters that conveniently provide decimal conversion from Zatoshi to "human-readable" ZEC decimal numbers.
[#397] Checkpoint format that supports NU5 TreeStates (#399) WalletBirthday now have both saplingTree and orchardTree values. The latter being Optional for checkpoints prior to Orchard activation height.
