storage encryption.
The password will be needed on startup with anchor channels.
Note that it remains possible to use non-encrypted storage
and keystore encryption with the command line.
- Separation between SwapManager and its transport:
Legacy transpport uses http, Nostr uses websockets
- The transport uses a context to open/close connections.
This context is not async, because it needs to be called
from the GUI
- Swapserver fees values are initialized to None instead
of 0, so that any attempt to use them before the swap
manager is initialized will raise an exception.
- Remove swapserver fees disk caching (swap_pairs file)
- Regtests use http transport
- Android uses http transport (until QML is ready)
This will be useful if we decide to ship lntransport as a separate
package. It is also a conceptual cleanup.
Notes:
- lntransport still requires crypto.py
- parsing node id from a bolt11 invoice is not supported.
If you closed a main_window soon after opening it, and the UpdateCheckThread network request was slow
and still in progress, the gui would freeze until the network request finished.
RunCoroutineDialog has a run() method that blocks the thread
without blocking the GUI (using exec), and a Cancel button
that cancels the coroutine.
main_window.run_coroutine_dialog() is a wrapper that returns
the coroutine result and may raise exceptions.
BlockingWaitingDialog was removed is transaction_dialog,
where it was not particularly useful.
- wallet.get_receiving_addresses is guaranteed to exist (maybe it was only for HD wallets in the past)
- wallet.is_mine is stricter than wallet.adb.is_mine, usually we want the former

Some checkboxes, e.g. main_window.warn_if_testnet became buggy with pyqt6:
looks like the stateChanged signal passes an int, not a Qt.CheckState.
(and note that Qt.CheckState is an Enum, not an IntEnum).
So `x == Qt.CheckState.Checked` would always evaluate to False.
```
def on_cb(_x):
print(f"heyheyhey. {_x=!r}, {Qt.CheckState.Checked=!r}, {cb.checkState()=!r}, {cb.isChecked()=!r}")
cb = QCheckBox("")
cb.stateChanged.connect(on_cb)
```
heyheyhey. x=2, Qt.CheckState.Checked=<CheckState.Checked: 2>, cb.checkState()=<CheckState.Checked: 2>, cb.isChecked()=True
heyheyhey. x=0, Qt.CheckState.Checked=<CheckState.Checked: 2>, cb.checkState()=<CheckState.Unchecked: 0>, cb.isChecked()=False
macOS reserves the "About" menu item name, similarly to "Preferences" (see a few lines above).
The "About" keyword seems even more strictly locked down:
not allowed as either a prefix or a suffix.
- With Qt5, a matching menu item is simply auto-recognised as the special "About" item,
- but with Qt6, it seems we explicitly have to do this dance, as directly adding
a menu item with the "About" name results in a segfault...

- rename globals
- also rm hardcoded strings from qml
- use consistent unit names in qml
(previously mixed sat/vB and sat/byte (latter coming from core lib))
I am only making this change as it makes it simpler to do manual testing of CPFP-ing *local* txs.
That is, by changing a few easy-to-find lines of code, I can make the GUI allow CPFP-ing a local tx, but
without this change it errors out with "unknown fee for parent transaction".
If one has an incoming local tx saved in the wallet, adb.get_tx_fee(txid) returns None
(if the tx gets into the mempool, it will use the server-reported value instead).
In contrast, wallet.get_tx_info(tx).fee calls both wallet.get_wallet_delta(tx) and adb.get_tx_fee(txid),
making it more expensive but more complete.
I think it's nicer for the network status to be rightmost, which was the case for a long time.
(Though plugins are still added after (via multiple different mechanisms, see 2fa, hww, revealer).
We could perhaps add a VLine separator, or add them to the left instead.)

qml: use backend sighash check and add user confirmation path
qt: use backend sighash check and add user confirmation path
qml: include get_warning_for_risk_of_burning_coins_as_fees test in txdetails
qt: add warning icon to sighash warning
add sighash and fee checks to wallet.sign_transaction, making all warnings fatal unless ignore_warnings is set to True
tests: test sign_transaction on both code paths with ignore_warnings True and False,
raise specific exceptions TransactionPotentiallyDangerousException and TransactionDangerousException
- no semantic changes, only moving code
- the change in qt/util.py is to avoid GC issues
- due to moving code, the group was moving out of scope and getting GC-ed,
as we only keep a reference to the vbox
(idea from 263fb2ba33 )
Somewhat a follow-up to 649ce979ab.
This adds some safety belts so we don't accidentally sign a tx that
contains a dummy address.
Specifically we check that tx does not contain output for dummy addr:
- in wallet.sign_transaction
- in network.broadcast_transaction
The second one is perhaps redundant, but I think it does not hurt.
Note that HTLCs must not be cancelled after the funding transaction
has been broadcast. If one want to cancel a swap once the funding
transaction is in mempool, one should double spend the transaction.
