test: Test new header sync behavior in loadtxoutset #29478

  1. fjahr commented at 11:29 pm on February 25, 2024: contributor

    It adds a test for the change to loadtxoutset made in #29345. Before that change the test doesn’t fail right away but times out after 10 minutes.

    Also removes a sync_blocks call that didn’t seem to do anything valuable.

    Why add two nodes to test this? Why not just delay the headers, check for the error message, and then submit the headers to the existing node?

    Yeah, that works as well, then I might as well test all nodes.
    fjahr commented at 5:19 pm on February 26, 2024:
    Actually no, now I remember why I did it this way. The dump is created later and so to there is a bit of reorganization needed in the test, so the change is more complex with this now. But I also found that the docs needed further fixing as well anyway.

    🚧 At least one of the CI tasks failed. Make sure to run all tests locally, according to the documentation.

    Possibly this is due to a silent merge conflict (the changes in this pull request being incompatible with the current code in the target branch). If so, make sure to rebase on the latest commit of the target branch.

    Leave a comment here, if you need help tracking down a confusing failure.

    nit: only fetching the headers rather than the full blocks seems to be sufficient here:

    0            block_header = n0.getblockheader(n0.getblockhash(i), verbose=False)
1            # make n1 and n2 aware of the new header, but don't give them the
2            # block.
3            n1.submitheader(block_header)
4            n2.submitheader(block_header)
    fjahr commented at 12:48 pm on March 13, 2024:
    I think that is already the case. Afaict getblock with verbosity 0 returns the same result as getblockheader with false. Inspired me to suggest this: #29646.
    fjahr commented at 1:33 pm on March 13, 2024:
    I will look into this as a follow-up, potentially improving getblockheader too since it’s confusing that this works
