Moves the logic requesting the forward swap into the TxEditor so it can
use the open transport and doesn't have to reconnect to the relays
again.
Also disables the "Preview" button in the TxEditor when the transaction will
send change to lightning.
This should prevent the user from saving the transaction to history and
broadcasting it later or exporting it and broadcasting it through some
external way.
Broadcasting needs to happen directly after the TxEditor so we can send
the second rpc call to the swapserver and await the incoming htlcs
before broadcasting the (funding-) transaction.
Update the TxEditor (onchain tab) if Send change to lightning is enabled
and the swap transport changes. Connect to swap transport if send change
to lightning gets enabled or if it is enabled and the TxEditor gets
opened.
This allows to nicely show the swap fees without blocking the UI to wait
until the swap manager gets initialized.
Check the swap providers liquidity as well if we try to send change to
lightning in `make_unsigned_transaction`. It is now expected that the
swap_manager is already initialized when calling
`make_unsigned_transaction`, otherwise no dummy output will get added.
Separates the swap transport initialization logic from the submarine
payment tab logic so it can be used for the send change to lightning
functionality too.
Also makes the gui updates on transport establishment more thread safe
by using pyqtSignals instead of calling gui methods from the asyncio
thread.
This must be an old regression.
The GUI was not allowing to open a wallet that did not have a password set:
it prompted for a password and did not accept any string (should at least accept empty "").
Without this, it was only possible to open a passwordless wallet if that was the first wallet the user opened
(as otherwise we would overwrite the empty pw with the pw of the current wallet).
- if multiple LN-enabled wallets are open, need to know which peer is for which wallet
- note: LNGossip is a singleton
- if a wallet is named LNGossip, can't distinguish. I think that's ok.
compare log lines:
before:
```
84.82 | I | lnpeer.Peer.[LNWallet, 034cc6216f-f8dcaa6e] | Disconnecting: GracefulDisconnect('Failed to initialize: TimeoutError()')
17.97 | D | lnpeer.Peer.[LNGossip, 0259d4116d-1618547b] | Sending INIT
```
after:
```
5.80 | D | lnpeer.Peer.[test_segwit_2, 038863cf8a-fd53ef9c] | Sending CHANNEL_READY
5.92 | D | lnpeer.Peer.[LNGossip, 038863cf8a-6286ffd4] | Received INIT
```
Completely removes the pin code authentication from qml. The config
option in the wallet preferences has been renamed to "Payment
authentication" and now either asks for the Android system
authentication (Biometric or system pin/password) if enabled or will ask
for the wallet password as fallback.
- by specifying "default=<VALUE>" in commands.py, <VALUE> would always overwrite what is in the config file
- note `$ ./run_electrum -o setconfig forget_config true` still does not work,
as that first sets forget_config in memory, and then - by virtue of the setting -
it refuses to write changes to the config file
- hence this option would have to be set manually by editing the json
(or as a CLI flag, as before)

Save the updated htlc set in `Peer._fulfill_htlc_set` and
`Peer._fail_htlc_set()` only after the loop iterated through all htlcs.
This potentially improves performance, especially considering that
writing the db can take >100 ms for larger wallets without partial
writes.
Repro steps:
- in qt gui, with network enabled, open wallet1
- open wizard, create wallet2 (restore from seed something that has mined history)
- close both wallets, stop electrum
- start electrum with "-o" offline flag, open wallet2
- observe all txs in history tab show up as "unconfirmed"
The cause is that "stored_height" only gets updated ~on new blocks.
So if you created a wallet and closed it soon, its db would not contain "stored_height."
Fixes the issue described in #10406.
When scanning a lightning invoice we would pass it to
`QEInvoiceParser.fromResolvedPaymentIdentifier()`, however
`fromResolvedPaymentIdentifier()` doesn't reset the state of
`QEInvoiceParser._lnurlData` which is used in QML to evaluate
`payImmediately: invoiceParser.isLnurlPay` in the `onValidationSuccess`
connection.
This change calls `clear()` in `fromResolvedPaymentIdentifier()` to
ensure that `QEInvoiceParser` state gets reset when loading a new invoice.
However when retrieving a bolt11 from a lnurl-pay callback we don't
wan't to reset `QEInvoiceParser._lnurlData` so that `payImmediately` is
true when confirming the lnurl pay dialog, for that I skip calling
`fromResolvedPaymentIdentifier()` and instead call `validateRecipient()`
directly so the `QEInvoiceParser` state doesn't get reset in this case.
Prevent DivisionByZero exceptions by returning `Decimal('NaN')
instead of `Decimal(0)` if the exchange rate is 0.
Fixes https://github.com/spesmilo/electrum/issues/10403
```
>>> bool(Decimal(0))
False
```
Adds close() no-op method to QEQRScanner to prevent type errors like
this:

```
There was a race incorrectly counting transactions with one
confirmations to the unconfirmed balance instead of the confirmed
balance.
This happened because the balance cache of AddressSynchronizer got
invalidated after `on_event_blockchain_updated` and then again after
`receive_history_callback`->`add_transaction`, however when calling
`AddressSynchronizer.get_balance()` before the tx got spv verified the
height would still be counted as 0 (unconfirmed), populating the balance
cache again with the unconfirmed balance.
I noticed this only on QML due to timing differences to Qt.
Invalidating the cache in `AddressSynchronizer.add_verified_tx()` after
the tx got verified causes the balance to get recalculated and shown
correctly.
- LNWallet no longer "is-an" LNWorker, instead LNWallet "has-an" LNWorker
- the motivation is to make the unit tests nicer, and allow writing unit tests for more things
- I hope this makes it possible to e.g. test lnsweep in the unit tests
- some stuff we would previously have to write a regtest for, maybe we can write a unit test for, now
- in unit tests, MockLNWallet now
- inherits LNWallet
- the Wallet is no longer being mocked
on_event_channels_updated doesn't get fired if channels change their
state to OPEN. TxEditor needs to use on_event_channel to notice channels
coming online.
I got confused how on_event_proxy_set can even work if CosignerWallet
doesn't inherit from EventListener until i figured out its children use
the EventListener too. To avoid this confusion i added two comments.
Fixes:
