"""Test the zapwallettxes functionality.
|
|
|
|
- start two bitcoind nodes
|
|
- create two transactions on node 0 - one is confirmed and one is unconfirmed.
|
|
- restart node 0 and verify that both the confirmed and the unconfirmed
|
|
transactions are still available.
|
|
- restart node 0 with zapwallettxes and persistmempool, and verify that both
|
|
the confirmed and the unconfirmed transactions are still available.
|
|
- restart node 0 with just zapwallettxes and verify that the confirmed
|
|
transactions are still available, but that the unconfirmed transaction has
|
|
been zapped.
