Add wallet events feed to TransactionManager and send pending changed
events on add and delete
Also
- Remove hardcoded values in the filter query
- Small improvement to query
Updates status-desktop #11233
Main changes:
- Refactor activity API to propagate token identities.
- Extend service to convert token identities to symbols for filtering
multi-transaction
- Filter transfers, pending_transactions and multi-transactions based
on the provided token identities
- Return involved token identities in activity API
- Test token filtering
Also:
- Fixed calling cancel on a filer activity completed task to release
resources
Notes:
- Found limitations with the token identity which complicates things
by not allowing to filter by token groups (like token-code does)
Updates status-desktop #11025
Change smart contract with new API.
Update gas amount for deployment.
Add Burn() and EstimateBurn() functions.
Add RemainingSupply() functions.
Issue #10816
fetch strategy:
Before:
- block fetching commands for different accounts were in the same wait
group, making them dependent on each iteration.
- transfers loading command was checking database for new unloaded
blocks on timeout and was in the same wait group with block fetching, so
it was often blocked until all block fetching commands finish for
iteration.
Now:
- block fetching commands run independently for each account
- transfers fetching command is run once on startup for unloaded blocks
from DB
- fetch history blocks commands are launched once on startup for
accounts with no full history loaded
- transfers are loaded on each iteration of block range check
without waiting for all ranges to be checked
Main changes:
- extend DB query include status for transactions and pending_transactions
- extend DB query to aggregate data from complex activity entries
- extend tests to include the new status values
Other changes:
- Improve tests with mocked addresses in DB to have a true to/from state
Update status-desktop #10746
Extended the migration process with a generic way of applying custom
migration code on top of the SQL files. The implementation provides
a safer way to run GO code along with the SQL migrations and possibility
of rolling back the changes in case of failure to keep the database
consistent.
This custom GO migration is needed to extract the status from
the JSON blob receipt and store it in transfers table.
Other changes:
- Add NULL DB value tracking to JSONBlob helper
- Index status column on transfers table
- Remove unnecessary panic calls
- Move log_parser to wallet's common package and use to extract token
identity from the logs
Notes:
- there is already an index on transfers table, sqlite creates one for
each unique constraint therefore add only status to a new index
- the planned refactoring and improvements to the database have been
postponed due to time constraints. Got the time to migrate the data
though, extracting it can be done later for a more efficient
implementation
Update status-desktop #10746
- reverted a change that stopped looking for ERC20 transfers if no nonce
and balance change found within a block range for ETH
- implemented sending EventRecentHistoryReady event at a proper time
- moved EventFetchingRecentHistory event to Strategy type as it does not make
sense to send this event in loop
- moved iterating through blocks logic to inside of `loadTransfers` command, which
now accepts a block range.
- reuse `uniqueHeaders` function in commands.go
- clean up
Updates #10246
It uses the current data only and doesn't extend with new types or
include new features in activity sources DBs.
Major changes:
- Partially filter by chain IDs
- Partially filter by Status if it is the case
- Partially filter by token types
- Filter by counterparty addresses
- Use wallet accounts for TO/FROM instead of filters
Closes: #10634
were stored in cache by pointers, which caused falsy cache hits in loop
because pointers with same address were created for different block
numbers. Now cache uses block numbers of uint64 as key, which can
overflow but it is not a problem since we use this cache for values
comparison, not as user data.
Fix crash on nil pointer in log.
Remove some unused code.
Protect nonceRanges with mutex while reading.
Updates #10246
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
Updates status-desktop #10366
Closes status-desktop #10633
This is done in Nim after the watched pending transaction changes state.
Note: tried to delete all transactions, not only multi-transaction,
as soon as the state is downloaded but it didn't work: noticed crashes
with minted transactions after restart.

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
prefixes. Changed primary keys and API methods.
Fixed tests and added new ones.
Fixed saved addresses and transaction tests to use ':memory:' sqlite
DB instead of a tmp file to speed up testing by hundred of times.
Fixes#8599
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
