I am not 100% this repo is a good place for code comments, let me know if it's not.
Maybe a dumb question, but why 0x40 is not here?

IIUC, 0x40 would be ANYPREVOUT|DEFAULT, so to speak. Instead it has to be ANYPREVOUT|ALL, which is 0x41

Yeah -- also, the same reason that 0x80 (ANYONECANPAY|DEFAULT) isn't there.

Doesn't this also make it ANYAMOUNT?

yes, SIGHASH_ANYPREVOUTANYSCRIPT
omits the script and the amount: https://github.com/bitcoin/bips/blob/master/bip-0118.mediawiki#signature-message

Perhaps instead of ANYPREVOUT
and ANYPREVOUTANYSCRIPT
, it would be better to name them ANYPREVOUTLIMITED
and ANYPREVOUT
? The latter verifies a particular pubkey is signing the output(s); the fomer is more limited, in that it also verifies that the prevout's scriptPubKey and value, and the particular tapscript that's being used.

Just had a look at the first commit for now.
- What do you think of making the random tests into fuzz targets?
- What do you think of having a
feature_anyprevout.py
functional with a very basic implementation of usecases? (For instance a trivial covenant, and a very basic eltoo channel where an outdated update is broadcast and the new one can be rebound.)
Also, a basic functional test that would sanity check a valid and invalid signature would fix BIP 118 (ANYPREVOUT) #4 (review).
Happy to help, of course. Not asking you to do it. I'm looking at a fuzz target currently that would assert the result of the "old" SignatureHashSchnorr
is always the same as the result of the "new" SignatureHashSchnorr
with KeyVersion::TAPROOT
.

All tests pass if i change this to always treat any ANYPREVOUT signature as valid.

Changing the semantic to the opposite will not fail any unit test.

I believe that if you use test/functional/feature_taproot.py --dumptests
and make the data available for script_assets_test
in test/script_tests.cpp
you'll get unit test failures for these sorts of changes. See test/fuzz/script_assets_test_minimizer.cpp
for some hints, though you don't need to actually run the fuzzer -- that just wastes less time.

… was conserved This fuzz targets copied the SignatureHashSchnorr function for Bitcoin Core 23.0 and checks the output of the APO-ready SignatureHashSchnorr from this branch against it. This is to make sure the behaviour of the function was not changed for non ANYPREVOUT keys, which would make some previously valid signatures invalid and, even worse, some previously invalid signatures valid.

How would you do that without duplicating the whole logic? |
I was thinking something like this: ajtowns@af2f34d#diff-a0337ffd7259e8c7c9a7786d6dbd420c80abfa1afdb34ebae3261109d9ae3c19R1661 There's not all that much logic to actually duplicate if you remove the non-APO cases. |

weak concept ACK for... but can be persuaded either way. I like the idea of the implementation being "obviously" matching the BIP even if somehow the 118 digest diverges from older sighashes in some unexpected way. |
Going to merge this as-is; note that it can be re-reviewed when a PR is opened to rebase it on top of 24.0 (or followup PRs can be proposed for this 23.0 branch too, of course) |
