5fe8100ff36fed6d50c2a25b028f57b25af3504c Change the wallet_backup.py test to use the restorewallet RPC command instead of restoring wallets manually. (lsilva01)
ae23faba6fc5cabc896f1175456d1018576f912d Add a new RPC command: restorewallet (lsilva01)
Pull request description:
As far as I know, there is no command to restore the wallet from a backup file.
The only way to do this is to replace the `wallet.dat` of a newly created wallet with the backup file, which is hardly an intuitive way.
This PR implements the `restorewallet` RPC command which restores the wallet from the backup file.
To test:
First create a backup file:
`$ bitcoin-cli -rpcwallet="wallet-01" backupwallet /home/Backups/wallet-01.bak`
Then restore it in another wallet:
`$ bitcoin-cli restorewallet "restored-wallet-01" /home/Backups/wallet-01.bak`

"""Test the wallet backup features.
|
|
|
|
Test case is:
|
|
4 nodes. 1 2 and 3 send transactions between each other,
|
|
fourth node is a miner.
|
|
1 2 3 each mine a block to start, then
|
|
Miner creates 100 blocks so 1 2 3 each have 500 mature
|
|
coins to spend.
|
|
Then 5 iterations of 1/2/3 sending coins amongst
|
|
themselves to get transactions in the wallets,
|
|
and the miner mining one block.
|
|
|
|
Wallets are backed up using dumpwallet/backupwallet.
|
|
Then 5 more iterations of transactions and mining a block.
|
|
|
|
Miner then generates 101 more blocks, so any
|
|
transaction fees paid mature.
|
|
|
|
Sanity check:
|
|
Sum(1,2,3,4 balances) == 114*500
|
|
|
|
1/2/3 are shutdown, and their wallets erased.
|
|
Then restore using wallet.dat backup. And
|
|
confirm 1/2/3/4 balances are same as before.
|
|
|
|
Shutdown again, restore using importwallet,
|
|
and confirm again balances are correct.
