04609284adrpc: Improve error when wallet is already loaded (Aurèle Oulès) Pull request description: Currently, trying to load a descriptor (sqlite) wallet that is already loaded throws the following error: > error code: -4 > error message: > Wallet file verification failed. SQLiteDatabase: Unable to obtain an exclusive lock on the database, is it being used by another instance of Bitcoin Core? I don't think it is very clear what it means for a user. While a legacy wallet would throw: > error code: -35 > error message: > Wallet file verification failed. Refusing to load database. Data file '/home/user/.bitcoin/signet/wallets/test_wallet/wallet.dat' is already loaded. This PR changes the error message for both types of wallet to: > error code: -35 > error message: > Wallet file verification failed. Wallet "test_wallet" is already loaded.
