    This PR enables one more of the non-wallet functional tests (mining_prioritisetransaction.py) to be run even with the Bitcoin Code wallet by using the MiniWallet instead, as proposed in #20078. Note that the adapted helper function create_lots_of_big_transactions is currently only used in this test, i.e. there was no need to change any others.

    I am not a fan of putting TODO in the source code. If (for any reason) they become stale, they will cause more damage/confusion than helping.

    It would be better as an issue, so that it can be tracked easier as the code evolves. Also it can be discussed easier and discarded trivially if needed without touching the code.

    Moreover, it seems that send_large_txs can be replaced by create_lots_of_big_transactions? Same for mine_large_block?

    I see your point, though I think creating an issue for merely refactoring three lines of code is a bit like taking a sledgehammer to crack a nut (and one also has to think about opening it after the PR is merged which “triggers” the TODO). Removed the TODO for now – replacing create_confirmed_utxos (and feature_dbcrash.py) with MiniWallet is one of the next things I’ll work on anyways and in the course of that I’ll check where it can dedup code.

    Moreover, it seems that send_large_txs can be replaced by create_lots_of_big_transactions? Same for mine_large_block?

    Good idea, I added a second refactoring commit doing exactly that. For that to work, I had to generalize create_lots_of_big_transactions a bit, in particular the possibility to not pass in any UTXOs (MiniWallet picks one of it’s internal UTXOs then in this case). Also it validates the fee now, like it’s done in send_large_txs, which I think makes a lot of sense.

    Force-pushed with suggestions from MarcoFalke taken into account. There is now a second commit which takes use of the brand-new shiny MiniWallet-variant of create_lots_of_big_transactions to deduplicate code. This PR affects the functional tests

    • mining_prioritisetransaction.py (obviously)
    • mempool_limit.py (send_large_txs is replaced by create_lots_of_big_transactions)
    • feature_maxuploadtarget.py (calls mine_large_block where also create_lots_of_big_transactions is used to replace part of its function)

    nit: create_lots_of_big_transactions is not introduced in this PR, but maybe include “send” in the name, to clearly indicate functionality?

    MarcoFalke commented at 7:31 am on June 14, 2022:

    I really wonder if it is worth it to move this to create_confirmed_utxos? Seems 2-3 LOC duplicated everywhere are fine compared to 1 LOC + import + definition in separate file?

    Maybe just remove create_confirmed_utxos?


    theStack commented at 11:17 pm on June 14, 2022:
    Right, I agree that it’s not worth it, calling send_self_transfer_multi with a subsequent generate is simple enough. Opened a follow-up PR: #25374
