Regression from df2bd61de6, where the
default hardened char was changed from "'" to "h". Note that there was
no corresponding wallet db upgrade, so some files use one char and
others use the other.
In one wallet, before this, make_unsigned_transaction() took 120 sec,
now it takes ~8 sec.
hot path:
```
make_unsigned_transaction (electrum/wallet.py:1696)
add_input_info (electrum/wallet.py:2261)
utxo (electrum/transaction.py:289)
tx_from_any (electrum/transaction.py:1232)
deserialize (electrum/transaction.py:805)
<listcomp> (electrum/transaction.py:805)
parse_output (electrum/transaction.py:706)
__init__ (electrum/transaction.py:127)
scriptpubkey (electrum/transaction.py:173)
get_address_from_output_script (electrum/transaction.py:672)
```
We were re-calculating txin.address from the prevtx-utxo on every call,
e.g. in electrum/gui/qt/utxo_list.py#L103 (for every utxo in the wallet).
For a wallet with ~1300 utxos, UTXOList.update() took ~3.2 sec before this,
now it's ~0.8 sec.
given a bip21 uri that has both onchain addr and bolt11,
if we have LN enabled but no LN channels, auto-fallback to paying onchain
we will have to clean up and unify this logic between GUIs. becoming spaghetti :/
rumour has it, Thomas has a branch? :P
B023 Function definition does not bind loop variable 'already_selected_buckets_value_sum'
in keepkey/qt.py, looks like this was an actual bug
(fixed in trezor plugin already: 52a4810752 )
B017 `assertRaises(Exception)` and `pytest.raises(Exception)` should be considered evil. They can lead to your test passing even if the code being tested is never executed due to a typo. Assert for a more specific exception (builtin or custom), or use `assertRaisesRegex` (if using `assertRaises`), or add the `match` keyword argument (if using `pytest.raises`), or use the context manager form with a target.
B008 Do not perform function calls in argument defaults. The call is performed only once at function definition time. All calls to your function will reuse the result of that definition-time function call. If this is intended, assign the function call to a module-level variable and use that variable as a default value.
