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
There's a problem withstanding:
````
▿ RustWeldingError
▿ genericError : 1 element
- message : "Error while fetching transparent balances for AccountId(0): Invalid column type Null at index: 0, name: address"
````
Which is fixed by commit `d0297bff0cdaaff42ad26f3be5bc261f6c828e8f` of "https://github.com/zcash/librustzcash".
nil-coalesce thrown errors on test so it reaches the end.
Make balance calls throwing to show underlying errors but nil-coalesce in non-throwing APIs
Add missing fulfill() calls
Add changelog entry
document and handle errors on getting shielded balance before
attempting to download sapling parameters.
- 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
This provides a method for clients to handle UI for text memo
limit correctly handling memos that are visibly fit within the
capacity defined in ZIP-302 but when encoded into UTF-8 bytes
their size exceeds such limit.
Closes#639
It's not good practice to make internal combine subjects accessible from
outside of SDK. So `lastState` is changed from `CurrentValueSubject` to
`Publisher`. This doesn't have any effect on public API. It just makes
SDK safer.
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#488
- When sync process is finished cache DB is removed from disk.
- Latest downloaded block is preserved becuase it's required to computes
in which phase to resume sync process.
- `SDKSynchronizer.latestDownloadedHeight` public API is removed
it makes no longer sense. This API was reading from cache DB.

Add tests that verify the state being reported properly
Fix `BlockBatchValidationTests`
Closes#614
fixes travis ci
Removed `setStartHeight` function
I’m going back in time and this setHeight is not something we are using anywhere else than in the prepare function. This comes from the times we had `initialize(seed:birthday) and we don’t have that anymore
See diff 246d10edaa (diff-414771774e10bc81260094ffcdc7b310a3be48758b2abd2bfae831c83912c02c)
The `func setStartHeight(_ startHeight: BlockHeight)` function assumes that
there might not be a wallet birthday set up or that it might be changed
in-flight which are things that are no longer happening.
remove test warning
Fix test compiler error
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.
