    This is a PR proposed in #20078

    This PR enables one more of the non-wallet functional tests (mempool_updatefromblock.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead.

    Overview:

    • Refactoring and removal of unnecessary imports and arguments to transaction_graph_test()
    • Improve logging
    • Decrease test execution time by ~70% (39s => 12s)

    scan_blocks is slightly quicker than generate, so instead we can use

  10. reemuru commented at 10:39 pm on May 20, 2021: none

    Updated with ac8b08b. Let me know if I missed anything! Also, should I roll theses commits up into one, or will they get squashed at merge time? Forgot to sign the first few. Recent changes:

    • self.wallet.generate(1) to self.wallet.scan_blocks(start=76, num=1)
    • remove blocks mined block_ids from cluttering logs along with unnecessary math import
    • put back enumerate for mempool properties checks
    • added assert before mining block
  11. DariusParvin commented at 0:37 am on May 21, 2021: contributor
    The changes look good to me! I’m relatively new myself but I think at this stage it would make sense to squash everything into one commit.

    sriramdvt commented at 4:42 pm on July 23, 2021:
    The old implementation of the test explicitly sets the ancestors and descendants of each transaction to form an acyclic tournament. However, wallet.send_self_transfer() only explicitly sets one ancestor for each transaction to form something like a singly linked list of size number of transactions. The acyclic tournament is then formed by the mempool. It would perhaps be a good idea to mention this in the description of transaction_graph_test

    In the earlier implementation of MiniWallet, tx_size had only one fixed value. To account for the varying sizes of transactions in the MiniWallet, it would be a better idea to calculate the transaction size from the transaction returned by send_self_transfer.

    Concept ACK

    Thanks for posting the profiling data! Definitely agree with more miniwallet usage, especially if it increases test execution speed. I compiled and ran the tests and everything passed, but I would definitely recommend running flake8 and making the suggested style changes. you can do this automatically with autopep8 (I did it by with the following steps):

    0pip install autopep8
1autopep8 --in-place mempool_updatefromblock.py

    you can double check the changes by running flake8 mempool_updatefromblock.py. you should only see line length warnings, which are fine to ignore

    Enables the mempool_updatefromblock non-wallet functional test
to be run even with the Bitcoin Core wallet disabled by using
the new MiniWallet instead.

- Refactoring and removal of unnecessary imports and arguments to
  transaction_graph_test()
- Improve logging
- Decrease test execution time by ~70% (39s => 12s)

    Thanks @MarcoFalke. I see skip_if_no_wallet is still in https://github.com/bitcoin/bitcoin/blob/master/test/functional/mempool_updatefromblock.py. I also checked each revision to the file since this PR was created, and don’t see any change making this PR irrelevant. Did I miss anything before determining it is useful to work on this?
