Everyone is _not_ connected in this test, so on slow machines
where this check triggers (e.g. the CI boxes) the test incorrectly
fails. This was also a source of (very infrequent) spurious failures
during the rebase.
Several conflicts in the C++ code related to the new `flags` parameter
to `CheckSignature` and the corresponding function being renamed upstream
to `CheckSignatureECDSA`.
Several conflicts in the test harness as Steven sorta pulled the new
upstream ECKey module into the Python code, and the actual upstream
code was slightly different. Also needed to update the feature_taproot
code to always use the non-RANGEPROOF sighash since dynafed is not
enabled in the Taproot test.
Also had to pull the `set_wif` method out of `ECKey` and inline it because
otherwise it triggers a "circular inclusion" error between script.py (which
would pull in `base58_to_bytes` from address.py) and address.py (which now
pulls in some taproot EC related stuff from script.py).
Noticed that #960 does not test the "sighash rangeproof flag set but no
witnesses" case.
Somehow the CECKey impl is really broken if you want to set
a raw private key. Core master already has a new impl so I just
took that one and replaces the usages. This will probably be equivalent
with what would be rebased in at a later stage.
This one was pretty brutal, but ultimately nothing too surprising.
Just had to keep track of which wallets owned which blinding keys,
and in wallet_importprunedfunds.py I had to manually create a
Liquid address.
This commit adds signet support, which is a little bit silly/redundant for us :)
Was a surprisingly easy merge to handle, and hopefully in future Core is more
mindful of signed blocks when they are changing code architecture.
I had to change a couple lines of src/signet.cpp to add blank assets to the
CTxOuts and to find transaction input scriptWitnesses. No need to add any
other tx witness data (and the CAsset()s that I did add to make things compile
won't be used..) because signet will always have g_con_elementsmode off.
