Removes the persisted payment info from lnworker once a swap got failed.
Stops persisting the OnionRoutingFailure as it is sufficient to delete
the payment info to fail potential incoming htlcs.
Deletes stored swap leftovers in lnworker and SwapManager
'prepayment', which corresponds to the trusted part of the
lightning payment.
We use 2*sm.mining_fee, where 'mining_fee' is the flat part of
the server fee. However, future protocol should probably allow
to set a value that does not depend on 'mining_fee'.
(note that LND uses a hardcoded amount).
Adds logic to retry sending a direct message in
`NostrTransport.send_direct_message()` on `TimeoutError`.
Handles `TimeoutError` exception more gracefully by catching it and
returning `None`.
`NostrTransport.update_relays()` raises a `KeyError` when the offer of
the configured swapserver (`config.SWAPSERVER_NPUB`) is not in
`self._offers` even though `sm.pairs_updated` gets triggered. This
happens because `NostrTransport.get_pairs()` called `sm.update_pairs()`
before adding the received offer to `self._offers`.
- if fee estimates are high atm, some outputs are not worth to sweep
- however, fee estimates might be only-temporarily very high
- previously in such a case lnwatcher would just discard outputs as dust,
and mark the channel REDEEMED (and hence never watch it or try again)
- now, instead, if the outputs would not be dust if fee estimates were lower,
lnwatcher will keep watching the channel
- and if estimates go down, lnwatcher will sweep them then
- relatedly, previously txbatcher.is_dust() used allow_fallback_to_static_rates=True,
and it erroneously almost always fell back to the static rates (150 s/b) during
startup (race: lnwatcher was faster than the network managed to get estimates)
- now, instead, txbatcher.is_dust() does not fallback to static rates,
and the callers are supposed to handle NoDynamicFeeEstimates.
- I think this makes much more sense. The previous meaning of "is_dust"
with the fallback was weird. Now it means: "is dust at current feerates".
fixes https://github.com/spesmilo/electrum/issues/9980
and differenciate between a single 'provider' and multiple or 0
'providers'. Also update SwapDialog and SwapServerDialog
when new offers are incoming. Stops translating f-string.
If `_fail_swap()` gets called multiple times (e.g. from callbacks) this
would race a `KeyError` as the swap got already popped from
`self._swaps`.
In theory `_fail_swap` unregisters itself from the lnwatcher callback
but the callback may is scheduled multiple times before it has the
chance to unregister itself.
disables the fee slider in the swap dialog for reverse swaps as the tx
fee for claiming is not configurable by the user. Also replaces calls to
`sm.get_swap_tx_fee()` with `sm.get_fee_for_txbatcher()` as this is the
correct fee estimate for claim transactions, instead of the config fee
eta used by `get_swap_tx_fee()`.
changes qeswaphelper to shate a single, long lived transport instance
instead of opening new transports to do swaps and fetch offers.
This allows to continuosly fetch offers, so events which get returned
later by slow relays don't get missed and the fee values stay updated.
Also fixes a race causing the list to miss some swapservers, as the
current implementation fetches only until
`swap_manager.is_initialized()` is set, which will get set as soon as an
event of the configured swapserver is received. So if the event of the
configured swapserver is received as first, all server events coming in
after it would get ignored.
introduces a class SwapOffer which is used instead of passing around
offers in dicts.
Also fixes incorrect variable naming of swapserver npubs / public keys
by assigning the npub instead of the hex pubkey to
config.SWAPSERVER_NPUB
