What a pain in the ass. This changes the `feature_cltv` functional test
to use the `MiniWallet`, an internal Pythonic wallet that produces
"signatures" consisting of several OP_NOPs in a row, so that this test
can be used when the wallet is disabled.
This means that the functions in feature_cltv which add a CLTV check and
change the locktime/sequence number no longer need to re-sign when they
change the txid, so they don't...HOWEVER, our Elements-specific
`feature_block_v4` test calls these functions with a real transaction
and depended on the re-signing behavior.
After several attempts at min-effort min-diff fixes I landed on this,
which simply sets the locktime at transaction creation and avoids having
to re-sign at all.
Also, I had to change the number of NOPs in the fake wallet code to make
a vsize assertion pass, presumably because of differences in Bitcoin/Elements
transaction serialization.
- run mempool_reorg.py even when the wallet is not compiled
- add `locktime` argument to `create_self_transfer` and `send_self_transfer`
- use more logs instead of comments
For the MiniWallet constructor, the two boolean parameters
"raw_script" and "use_p2pk" are replaced by a single parameter of the
newly introduced type MiniWalletMode (derived by enum.Enum), which can
hold the following values:
- ADDRESS_OP_TRUE
- RAW_OP_TRUE
- RAW_P2PK
Adds two new features to MiniWallet:
* The fee rate is irrelevant sometimes, so just set an arbitrary default
* The utxo to spend needs to be selected manually sometimes
