Closes#484.
- `TransactionRepository` has async API. `Synchronizer` and alternative
APIs are updated accordingly.
These methods and properties in the `Synchronizer` are async now:
- `cancelSpend(transaction:)`
- All the variants of the `getMemos(for:)` method.
- All the variants fo the `getRecipients(for:)` method.
- `allConfirmedTransactions(from:limit:)`
- `pendingTransactions`
- `clearedTransactions`
- `sentTransactions`
- `receivedTransactions`
Closes#209.
[#845] Introduce ZcashSynchronizerAlias enum
Closes#845.
[#852] SDKSynchronizer using queues label based on the alias
Closes#852.
[#847] Remove posibility to use DatabaseStorageManager as singleton
Closes#847.
[#850] Remove synchronizerConnectionStateChanged notification
Closes#850.
[#855] Add check if the Alias is already used
Closes#855
- Added `UsedAliasesChecker` utility which is used to register aliases
that are in use.
- `prepare()` and `wipe()` methods now check if the current alias can't
be used and if not then `InitializerError.aliasAlreadyInUse` is
thrown/emitted.
- Some public methods that could cause harm if used with the Alias that
is already in use now throw `SynchronizerError.notPrepared`. Thanks to
this the client app is forced to call `prepare()` first. And
`prepare()` does check for the Alias.
- Added tests for new conditions.
[#849] Make InternalSyncProgress aware of the Alias
Closes#849.
[#853] Only instance with default Alias migrates legacy cache DB
Closes#853.
[#851] Apply the Alias to the URLs
Closes#851.
- `Initializer` now updates paths according to alias before paths are
used anywhere in the SDK.
- Paths update can fail. It would be incovenient for the client apps to
handle errors thrown from `Initiliazer` constructor. So the error is
then handled in `SDKSynchronizer.prepare()` or `SDKSynchronizer.wipe()`.
[#846] Stop using SDKMetrics as singleton (#862)
- metrics are not longer a singleton
- tests fixed
- metrics outside init of the synchronizer
[#848] Make logger aware of the alias
- logger is now an instance passed throughout the sdk instead of a static proxy
[#848] Make logger aware of the alias (#868)
- comments addressed
[#848] Make logger aware of the alias (#868)
- returning protocol back
Fix typos
[#856] Add possibility to test multiple synchronizers in the sample app
Closes#856.
- Added `alias` property to `Synchronizer`.
- Added `SyncBlocksListViewController` which provides UI to use multiple
synchronizers at once.
[#209] Add changelog
- Add changelog for #209.
- Overall improve readability of the rendered changelog. Tickets
references are now prefixed with `###` instead of `- `.
Fix compilation
This change introduces two new protocols: `ClosureSynchronizer` and
`CombineSynchronizer`. These two protocols define API that doesn't use
`async`. So the client can choose exactly which API it wants to use.
This change also introduces two new objects: `ClosureSDKSynchronizer`
and `CombineSDKSynchronizer`. These two implement the respective protocols
mentioned above. Both are structures. Neither of these two keeps any state.
Thanks to this each is very cheap to create. And usage of these two isn't
mutually exclusive. So devs can really choose the best SDK API for each
part of the client app.
[#831] Use async inside of the SDKSynchronizer
- In general lot of methods inside the `SDKSynchronizer` and
`CompactBlockProcessoer` which weren't async are now async. And other
changes are made because of this change.
- `CompactBlockProcessor` no longer uses Combine to communicate with
`SDKSynchronizer`. Reason for this is that Combine doesn't play great
with async. Closure passed to `sink` isn't async.
- Because of this and because of how our tests work (receiving signals
from CBP directly) `CompactBlockProcessor` must be able to handle more
event closures. Not just one. So it now has `eventClosures`
dictionary. It's little bit strange but it works fine.
- `SyncStatus` inside the `SDKSynchronizer` was previously protected by
lock. Now it's protected by simple actor wrapper.
- Changes in tests are minimal. Changes were mady only because
`CompactBlockProcessor` changes from Combine to closures.
[#831] Add tests for ClosureSDKSynchronizer
- Added tests are testing in general if the `ClosuresSDKSynchronizer` is correctly
calling `Synchronizer` and if the values are correctly returned.
- `ClosuresSDKSynchronizer` doesn't contain any logic but it is public
API and we should be sure that it works correctly.
