Since we have a mockable wallet database, we don't really need to be using BDB or SQLite's in-memory database capabilities. It doesn't really help us to be using those as we aren't doing anything that requires one type of db over the other, and will just prefer SQLite if it's available. MockableDatabase is suitable for these uses, so use CreateMockableWalletDatabase to use that. -BEGIN VERIFY SCRIPT- sed -i "s/CreateMockWalletDatabase(options)/CreateMockableWalletDatabase()/" $(git grep -l "CreateMockWalletDatabase(options)" -- ":(exclude)src/wallet/walletdb.*") sed -i "s/CreateMockWalletDatabase/CreateMockableWalletDatabase/" $(git grep -l "CreateMockWalletDatabase" -- ":(exclude)src/wallet/walletdb.*") -END VERIFY SCRIPT-
