which supported scanning in batches for better visibility into scan
progress. Also updated Cargo files to support error-free build for the
beta release.
Addresses some of the concerns in https://github.com/zcash/zcash-android-wallet/issues/39 by removing the side effects from the Intializer. Now instead of trying to help with loading and persisting wallet birthdates, it delegates that utility to another class.
This involves splitting code to run in the zcashMainnet and zcashTestnet flavors and using the corresponding feature of librustzcash. Mainnet functionality is proven in the integration test in androidTestZcashmainnet.
Leverage the new flow-centric approach to sending transactions, rather than polling the database, which leads to concurrent modification errors and corrupted data.
- Convert status flags into stream of statuses, instead.
- Improve logging during transaction submission
- Database corrections. Aparently Room has gotten more strict with schema parsing and this required lots of corrections mainly around get nullability correct for DB fields.
- Simplify Synchronizer creation via constructor functions. Created one function for maximum simplicity and another for maximum flexibility.
- Changed logic for Wallet initialization to simplify dependencies and allow for optional access to private keys for wallet apps
- Created TransactionRepository that leverages the paging library for Room
- Provided sample implementation of bridging to a key manager in a way where wallet apps do not have to modify their existing code.
- Made it easier to clear the wallet data that can be repopulated from the blockchain
- Allowed for better cleanup of heavy-weight lightwalletd services by adding a shutdown API call
These changes largely reduce the amount of configuration that can be tweaked in order to prevent fragmentation of the anonymity set of users. If wallet makers change certain properties than it can become easy to detect which network requests are coming from which client. The goal is for clients to be as anonymous as possible.
- Correct typo and compiler warning in Rust.
'trait objects without an explicity dyn' are deprecated and this is a warning as of Rust 1.37
- update dependencies
- update documentation
