This PR enables one more of the non-wallet functional tests (feature_dbcrash.py) to be run even with the Bitcoin Code wallet by using the MiniWallet instead, as proposed in #20078.

What about setting this to 0 by default for MiniWallet?

MarcoFalke commented at 3:15 PM on May 16, 2022:

Also, it seems confusing that this needs to be set at all. Why would a fee of 1000 sat be ever too high?

theStack commented at 3:58 PM on May 19, 2022:

maxfeerate=0 is set here only for performance reasons, to skip this part in the course of the sendrawtransaction RPC: https://github.com/bitcoin/bitcoin/blob/0de36941eca1bff91420dd878eb097db2b1a596c/src/node/transaction.cpp#L71-L80

With the fee-check enabled, the iterations take about twice as long (~2mins instead of ~1min on my machine). Added a comment to clarify.

MarcoFalke commented at 3:23 PM on May 16, 2022:

Not sure about using the private member here. What about def get_utxos(self, *, mark_as_spent=True): return copy.copy(self._utxos) or so?

theStack commented at 3:59 PM on May 19, 2022:

Agree, accessing private members should be avoided. Thanks, done.
