Refactor the filter interface to be an async call which returns
the result using a wallet event
A call to the filter API will cancel the ongoing filter and receive
an error result event
Closes status-desktop #10994
This commit does a few things:
1) Extend create/import account endpoint to get wallet config, some of
which has been moved to the backend
2) Set up a loop for retrieving balances every 10 minutes, caching the
balances
3) Return information about which checks are not passing when trying to
join a token gated community
4) Add tests to the token gated communities
5) Fixes an issue with addresses not matching when checking for
permissions
The move to the wallet as a background task is not yet complete, I need
to publish a signal, and most likely I will disable it before merging
for now, as it's currently not used by desktop/mobile, but the PR was
getting to big
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
Add history.exchange sub-package with following responsibilities
- fetch and caches daily exchange rates for tokens
- Partial update if missing form yesterday back
- Implement all time fetching special case
- Fetches the price of the token after merging entries for the selected
chains
history.service package changes
- Return ValuePoint instead of DataPoint
- Value point contains the value in fiat as float64 instead
- Convert merged values from tokens balance (wei) to fiat
Other changes
- Move start/stop balance history to startWallet/stopWallet
- Move cryptocompare to thirdparty package to avoid recursive import
- Rename DataPoint.Value to DataPoint.Balance
- Don't merge entries for single chain
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

Remove Favourites APIs and update the saved address APIs
Added up migration scripts that move the favourites from the old table
to the saved_addresses table with true flag and then drop the favourites table.
Required by #6546
Added functionality to find target address when 6th param in path is added
for ex: "m'/44'/60'/0'/0/500" reperents the Address at the 500th index
Added a api to get the Address derived from a private key
* feat: enable wallet without network binding
* feat: make transfer network aware
* feat: allow to pass initial networks via config
* fix: nil check and feed
* feat: Add documentation with better function name
* fix: do not init the manager more than once
* fix: PR feedbacks
* Bump version
* Update Jenkinsfile.tests
* Convert int to string

- old existing ranges are merged when wallet service is started
- a new range is merged with an existing one if possible
This will decrease the number of entries in blocks_range table as
currently it can grow indefinitely (@flexsurfer reported 23307 entries).
This change is also needed for further optimisations of RPC usage.
- Wallet service is not started on foreground event on status-go side
anymore, it leaves a client side opportunity to decide whether new
blocks should be watched.
- `watchNewBlocks` parameter is added to `StartWallet`.
- Some requests are removed/moved to the place where they are necessary.
StartWallet was called before service initialization.
After the recent changes this call was moved after initialization, but
the geth system automatically start services.
This meant that `IsStarted()` returned true, although the reactor was
not started, and only after calling `StopWallet()` and `StartWallet()`
again the system would reach the right state.
This commit changes the behavior so that we only check whether the
reactor has been started when calling `IsStarted()` and we allow
multiple calls to `Start()` on the signal service, which won't return an
error (it's a noop if callled multiple times).
