Mainly refactor API to have control on pending_transactions operations.
Use the new API to migrate the multi-transaction ID from to transfers
in one SQL transaction.
The refactoring was done to better mirror the purpose of pending_transactions
Also:
- Externalize TransactionManager from WalletService to be used by
other services
- Extract walletEvent as a dependency for all services that need to
propagate events
- Batch chain requests
- Remove unused APIs
- Add auto delete option for clients that fire and forget transactions
Updates status-desktop #11754
Add the possibility of retrieving the metadata of wallet activity based
on the given filter criteria.
Current implementation relies that after fetching the metadata, user
will follow up with more requests for details. However, after some
experimenting I'm considering extracting all required information
for the summary viewing while filtering. This way there will be no
need for another batch requests for transfers, multi-transactions and
pending transactions to show the summary. Only when user wants to see
the details for one will specifically request it.
For this first prototype, the filter criteria is limited to:
- time
- type
- addresses
Major changes:
- Add the filter definition to be used in propagating the filter
information
- Add GetActivityEntries API to return the list of activity entries
for the given addresses/chainIDs by a view in the complete list
- GetTransfersForIdentities to batch retrieve further details of the
transfers
- GetPendingTransactionsForIdentities to batch retrieve further details
of the pending transactions
- Added a new package testutils for tests.
- Added tests

strategies.
On mobile devices we might not want to load all transfers history
to avoid high internet traffic consumption or to save some space.
On desktop we will load all transfers in background.
- Moved current fetching transfers implementation to
OnDemandFetchStrategy
- Implemented QueuedAtomicGroup to cache outgoing commands above a
threshold
- Refactored some type names, methods for better clarity:
- LastKnownBlock name was misused
- Block renamed to BlockDAO to clarify what it does and avoid
confusion with geth Block type
- Cleanup - removed unused parameters and types' members
- Changed tests to use in memory DB for speedup
- Added more logging and comments
Updates #10246
Extends wallet module with the history package with the following
components:
BalanceDB (balance_db.go)
- Keeps track of balance information (token count, block, block timestamp)
for a token identity (chain, address, currency)
- The cached data is stored in `balance_history` table.
- Uniqueness constrained is enforced by the `balance_history_identify_entry`
UNIQUE index.
- Optimal DB fetching is ensured by the `balance_history_filter_entries`
index
Balance (balance.go)
- Provides two stages:
- Fetch of balance history using RPC calls (Balance.update function)
- Retrieving of cached balance data from the DB it exists (Balance.get
function)
- Fetching and retrieving of data is done for specific time intervals
defined by TimeInterval "enumeration"
- Update process is done for a token identity by the Balance.Update function
- The granularity of data points returned is defined by the constant
increment step define in `timeIntervalToStride` for each time interval.
- The `blocksStride` values have a common divisor to have cache hit
between time intervals.
Service (service.go)
- Main APIs
- StartBalanceHistory: Regularly updates balance history for all
enabled networks, available accounts and provided tokens.
- GetBalanceHistory: retrieves cached token count for a token identity
(chain, address, currency) for multiple chains
- UpdateVisibleTokens: will set the list of tokens to have historical
balance fetched. This is a simplification to limit tokens to a small
list that make sense
Fetch balance history for ECR20 tokens
- Add token.Manager.GetTokenBalanceAt to fetch balance of a specific
block number of ECR20.
- Add tokenChainClientSource concrete implementation of DataSource
to fetch balance of ECR20 tokens.
- Chose the correct DataSource implementation based on the token
"is native" property.
Tests
Tests are implemented using a mock of `DataSource` interface used
to intercept the RPC calls.
Notes:
- the timestamp used for retrieving block balance is constant
Closes status-desktop: #8175, #8226, #8862
Add functionality to sample and retrieve balance history and cache
it in memory for the current transfer controller.
The end of the balance history is snapped at twice per day to
avoid having to query the blockchain again for each fetching within
12 hours interval
The functionality will be extended with DB caching, API call batching,
"smarter" cache hitting and syncing between devices
