Adds unittests for `LNWallet.open_channel_just_in_time()`,
`LNWallet._cleanup_failed_jit_channel()`,
`LNWallet.can_get_zeroconf_channel()` and
`LNWallet.receive_requires_jit_channel()`.
Adds cleanup logic to `LNWallet.open_channel_just_in_time` so
that the channel provider removes unfunded channels again, e.g. if
the client didn't release the preimage or the provider failed
to broadcast the funding transaction.
Also adds more robust transaction broadcast logic so we retry to
broadcast if it failed and check against adb to see if any previous
broadcast was successful.
...so we can have multiple just in time channels with the same lsp.
We already save a remote scid alias in `on_channel_ready` which we
already have received after the new zeroconf channel is in open state.
So setting the alias to the static node id hash is counterproductive
because it doesn't allow to differentiate between channels.
Also extends the regtest (`just_in_time`) to do a second channel
opening, to cover this scenario. This doesn't add much runtime to
the test, so the cost seems reasonable.
On LSP side we were only checking if ACCEPT_ZEROCONF_CHANNELS
is enabled while forwarding a non-trampoline htlc.
During trampoline forwarding the config was ignored.
The ACCEPT_* prefix implied this was only for accepting inbound
zeroconf channels, but it also controls whether we open them when
forwarding HTLCs.
Renames the config var to OPEN_ZEROCONF_CHANNELS
to clarify it enables zeroconf channel opens in both directions,
and add the missing check when forwarding trampoline HTLCs.
Fixes AbstractChannel.update_unfunded_state to stop calling a
non-existent method (unwatch_channel).
Adds unittest to execute the zeroconf path of update_unfunded_state.
Add unittest that verifies we only include r_tags for trampoline nodes
if we signal trampoline support in the invoice_features and only signal
trampoline support if we use trampoline or have only open trampoline
channels.
Make the trampoline signaling in bolt11 invoices dependent upon all
unfrozen channels being with trampoline peers instead of the trampoline
config.
Stops automatically freezing non-trampoline channels for receiving if
trampoline is enabled.
One effect of this change is that now we don't signal trampoline support
anymore in the invoice even if trampoline is enabled, if one of the
channels is with a non trampoline peer.
rm the `assert fee >= 0, f"{fee=!r} must be non-negative satoshis"`
from `Abstract_Wallet.get_tx_fee_warning()` to prevent an exception when
users load a psbt with negative tx fee.
It is much easier to reason about the rpcserver if we don't allow changing its basic settings while it is already running. What does it mean to change the TCP port it is listening on ("rpcport") if it's already running? It is even problematic to change the rpcpassword: care needs to be taken to already update it for the current server.
(ref https://github.com/spesmilo/electrum/issues/6762)
This commit disallows changing all of the "rpc*" config variables if the daemon is already running.
---
Simultaneously, it also ensures rpc_password is always set and auth cannot be disabled.
Previously if there was a daemon running, and the user ran
`$ electrum setconfig rpcpassword ""` that would leave the RPC unauthenticated
for the current session. However next time the daemon restarted, get_rpc_credentials would see
the unset password and generate one.
I think this was the worst of both worlds:
- we did not really allow removing the rpc password, except for the current session, and
- perhaps unexpectedly, we would generate a new password on daemon restart
Instead now we explicitly make sure the RPC server can never get into a state where it does not have a password set.

The 2fa secret is not selectable or copyable, this is very inconveniant
when setting up a new 2fa wallet as the user has to somehow manually
write the secret e.g. on a paper to then enter it again in their 2fa
app. This makes the secret string copyable by clicking on it.
Catch NetLegacySinglesigScriptType and convert it to a
UserFacingException if the user tries to import a private key for which
it is not possible to get a singlesig descriptor (e.g. p2wsh).

- could not find a single project that still actually cares about bip70 [0]
- well except maybe BitPay.
- but I cannot test with BitPay:
- they have a testnet3 staging environment on test.bitpay.com
- but the SSL cert they use for bip70 has expired in 2021
- the webUI probably also has not been updated since then...
- they claim to have added LN support in 2022 in a blog post,
but it's not there on test.bitpay.com
- on mainnet, they require KYC before payment
- < ... angry noises >
- their loss then, I don't care.
- this is code that no one wants to maintain
- this does not yet delete the signed bip70 payment data for historical txs
- but it is no longer possible to export it from the GUI

As it's failing due to relative imports, this might have been broken since py2->py3 migration.

The `until` filter would limit the relay to only send us events created
up until this timestamp. If the user opens a swap transport by opening
the swap dialog, and keeps the dialog open the dialog will naturally age
above this limit and the relay will stop sending the client swapserver
events as they have (legitimately) been created after this timestamp.
As sanity check we still have the comparison against the current
timestamp in the event parsing loop to prevent pre/backdating.
