When moving the lightning fee slider in the SettingsDialog by clicking
on the range instead of pulling the slider the new fee value wouldn't
get stored in the config as the sliderRelased signal is only emitted
when the slider is pulled.
This change updates it on valueChanged.
Adds validation and deduplication of the relay urls entered in the QT
settings dialog. This is supposed to prevent malformed or duplicated
relay entries.
Also resets the relays to the default value if no (valid) url
is entered. This prevents the user from getting stuck without relays
(otherwise the user would have to research for relay urls manually if
they don't know any).
The option to add a 2nd trampoline hop to legacy trampoline payments requires too much space in the trampoline onion.
Because the trampoline onion has only limited space of 400b and the payload with 2nd t hop and no r_tags already requires 392b it is essentially unusable for payments that require routing hints to be included in the onion
(because the receiver has no direct channel to the 2nd trampoline node)
as there is no space left to include them (1r_tag == ~52b).
running a watchtower requires to be able to run a daemon with the
watchtower plugin enabled. If users succeed at doing that, we
can expect them to be able to configure theclient using the
command line.
(that would not work with QML, though. maybe QML could use an
advanced config editor)
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
A new config API is introduced, and ~all of the codebase is adapted to it.
The old API is kept but mainly only for dynamic usage where its extra flexibility is needed.
Using examples, the old config API looked this:
```
>>> config.get("request_expiry", 86400)
604800
>>> config.set_key("request_expiry", 86400)
>>>
```
The new config API instead:
```
>>> config.WALLET_PAYREQ_EXPIRY_SECONDS
604800
>>> config.WALLET_PAYREQ_EXPIRY_SECONDS = 86400
>>>
```
The old API operated on arbitrary string keys, the new one uses
a static ~enum-like list of variables.
With the new API:
- there is a single centralised list of config variables, as opposed to
these being scattered all over
- no more duplication of default values (in the getters)
- there is now some (minimal for now) type-validation/conversion for
the config values

closes https://github.com/spesmilo/electrum/pull/5649
Note: there is yet a third API added here, for certain niche/abstract use-cases,
where we need a reference to the config variable itself.
It should only be used when needed:
```
>>> var = config.cv.WALLET_PAYREQ_EXPIRY_SECONDS
>>> var
<ConfigVarWithConfig key='request_expiry'>
>>> var.get()
604800
>>> var.set(3600)
>>> var.get_default_value()
86400
>>> var.is_set()
True
>>> var.is_modifiable()
True
```
That way, users can see the effects settings directly on their transaction.
This changes the API of make_tx:
- get_coins is called inside make_tx, so that inputs can be changed dynamically
- make_tx takes an optional parameter: unconfirmed_only, passed to get_coins
- ConfirmTxDialog detects if we can pay by disabling confirmed_only or lowering fee
preference from the GUI, because the mempoolfullrbf option in
Bitcoin 0.24 makes RBF signaling pretty meaningless. Fixes#8088.
Note: RBF remains disabled for channel funding transactions.
In that case, the flag is actually only used as a semaphore
between different instances of the same wallet.
Use refresh_row() for address, utxo and contact lists.
Replace unneeded calls to update_tabs() with refresh_tabs()
Fix right-click menu after selecting multiple addresses.
