This is the first step of improvements over keypairs/keycards/accounts.
- `SyncKeypairFull` protobuf removed
- `SyncKeypair` protobuf is used for syncing all but the watch only accounts
- `SyncAccount` is used only for syncing watch only accounts
- related keycards are synced together with a keypair
- on any keypair change (either it's just a keypair name or any change made over an
account which belongs to that keypair) entire keypair is synced including related keycards
- on any watch only account related change, that account is synced with all its details
- old `accounts` table is moved/mapped to `keypairs` and `keypairs_accounts`
- `keycards` table has foreign key which refers to `keypairs.key_uid`
- `Keypair` introduced as a new type
- api endpoints updated according to this change
This commit renames few api endpoints:
- old `AddMigratedKeyPairOrAddAccountsIfKeyPairIsAdded` renamed to `AddKeycardOrAddAccountsIfKeycardIsAdded`
- old `GetAllMigratedKeyPairs` renamed to `GetAllKnownKeycardsGroupedByKeyUID`
- old `GetMigratedKeyPairByKeyUID` renamed to `GetKeycardByKeyUID`
- old `DeleteKeypair` renamed to `DeleteAllKeycardsWithKeyUID`
`type` column is set for all rows to appropriate value. Before this change
accounts which were generated from the keypair created importing seed phrase
had `generated` value for the `type`.
According to above, a function for generating an account sets the `type`
based on the passed derive from address.
`last_update_clock` will be used later for synchronization.
All keypair functions take clock value in consideration when
making a decision whether to perform an action or not.
Both functions `DeleteAccount` and `AddMigratedKeyPair` require password to be provided
in order to delete account from the keystore properly (removing account from the cache and
deleting corresponding local keystore file).
Password parameter can be also an empty string, since there are cases when an account is
not added to the keystore (in case of keycard account), so we have nothing to delete.
This tests the entire process of converting a regular account to a keycard
account and then converting that keycard account back to a regular account.
For the need of this test I had to improve `DeleteAccount` function, cause the
previous implementation didn't remove account from the keystore cache, but
only from the keystore.
Handling results of `GetAllMigratedKeyPairs` and `GetMigratedKeyPairByKeyUID`
endpoints updated in a way that account address is unique in the address list.
The following three new functions introduced, for which password should be verified
on the client side (in case of a keycard user we don't have keystores to check pass):
- `AddAccountWithMnemonicPasswordVerified`
- `AddAccountWithMnemonicAndPathPasswordVerified`
- `AddAccountWithPrivateKeyPasswordVerified`
- `GenerateAccountPasswordVerified`
- `GenerateAccountWithDerivedPathPasswordVerified`
update
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
* Sync Settings
* Added valueHandlers and Database singleton
Some issues remain, need a way to comparing incoming sql.DB to check if the connection is to a different file or not. Maybe make singleton instance per filename
* Added functionality to check the sqlite filename
* Refactor of Database.SaveSyncSettings to be used as a handler
* Implemented inteface for setting sync protobuf factories
* Refactored and completed adhoc send setting sync
* Tidying up

* Breakout structs
* Tidy up
* Refactor of bulk settings sync
* Bug fixes
* Addressing feedback
* Fix code dropped during rebase

* Fix for node config related crashes
* Provisional fix for type assertion - issue 2
* Adding robust type assertion checks
* Partial fix for null literal db storage and json encoding
* Fix for passively handling nil sql.DB, and checking if elem has len and if len is 0
* Added test for preferred name behaviour
* Adding saved sync settings to MessengerResponse
* Completed granular initial sync and clock from network on save
* add Settings to isEmpty

*** How it worked before this PR on multiaccount creation:
- On multiacc creation we scanned chain for eth and erc20 transfers. For
each address of a new empty multiaccount this scan required
1. two `eth_getBalance` requests to find out that there is no any
balance change between zero and the last block, for eth transfers
2. and `chain-size/100000` (currently ~100) `eth_getLogs` requests,
for erc20 transfers
- For some reason we scanned an address of the chat account as well, and
also accounts were not deduplicated. So even for an empty multiacc we
scanned chain twice for each chat and main wallet addresses, in result
app had to execute about 400 requests.
- As mentioned above, `eth_getBalance` requests were used to check if
there were any eth transfers, and that caused empty history in case
if user already used all available eth (so that both zero and latest
blocks show 0 eth for an address). There might have been transactions
but we wouldn't fetch/show them.
- There was no upper limit for the number of rpc requests during the
scan, so it could require indefinite number of requests; the scanning
algorithm was written so that we persisted the whole history of
transactions or tried to scan form the beginning again in case of
failure, giving up only after 10 minutes of failures. In result
addresses with sufficient number of transactions would never be fully
scanned and during these 10 minutes app could use gigabytes of
internet data.
- Failures were caused by `eth_getBlockByNumber`/`eth_getBlockByHash`
requests. These requests return significantly bigger responses than
`eth_getBalance`/`eth_transactionsCount` and it is likely that
execution of thousands of them in parallel caused failures for
accounts with hundreds of transactions. Even for an account with 12k
we could successfully determine blocks with transaction in a few
minutes using `eth_getBalance` requests, but `eth_getBlock...`
couldn't be processed for this acc.
- There was no caching for for `eth_getBalance` requests, and this
caused in average 3-4 times more such requests than is needed.
*** How it works now on multiaccount creation:
- On multiacc creation we scan chain for last ~30 eth transactions and
then check erc20 in the range where these eth transactions were found.
For an empty address in multiacc this means:
1. two `eth_getBalance` transactions to determine that there was no
balance change between zero and the last block; two
`eth_transactionsCount` requests to determine there are no outgoing
transactions for this address; total 4 requests for eth transfers
2. 20 `eth_getLogs` for erc20 transfers. This number can be lowered,
but that's not a big deal
- Deduplication of addresses is added and also we don't scan chat
account, so a new multiacc requires ~25 (we also request latest block
number and probably execute a few other calls) request to determine
that multiacc is empty (comparing to ~400 before)
- In case if address contains transactions we:
1. determine the range which contains 20-25 outgoing eth/erc20
transactions. This usually requires up to 10 `eth_transactionCount`
requests
2. then we scan chain for eth transfers using `eth_getBalance` and
`eth_transactionCount` (for double checking zero balances)
3. we make sure that we do not scan db for more than 30 blocks with
transfers. That's important for accounts with mostly incoming
transactions, because the range found on the first step might
contain any number of incoming transfers, but only 20-25 outgoing
transactions
4. when we found ~30 blocks in a given range, we update initial
range `from` block using the oldest found block
5. and now we scan db for erc20transfers using `eth_getLogs`
`oldest-found-eth-block`-`latest-block`, we make not more than 20 calls
6. when all blocks which contain incoming/outgoing transfers for a
given address are found, we save these blocks to db and mark that
transfers from these blocks are still to be fetched
7. Then we select latest ~30 (the number can be adjusted) blocks from
these which were found and fetch transfers, this requires 3-4
requests per transfer.
8. we persist scanned range so that we know were to start next time
9. we dispatch an event which tells client that transactions are found
10. client fetches latest 20 transfers
- when user presses "fetch more" button we check if app's db contains next
20 transfers, if not we scan chain again and return transfers after
small fixes
