- 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
Allows storing two different payment info of the same payment hash by
including the direction into the db key.
We create and store PaymentInfo for sending attempts and for requests (receiving),
if we try to pay ourself (e.g. through a channel rebalance) the checks
in `save_payment_info` would prevent this and throw an exception.
By storing the PaymentInfos of outgoing and incoming payments separately in
the db this collision is avoided and it makes it easier to reason about
which PaymentInfo belongs where.
Splits `LNWallet.dont_settle_htlcs` into `LNWallet.dont_settle_htlcs`
and `LNWallet.dont_expire_htlcs`.
Registering a payment hash in dont_settle_htlcs will prevent it from
getting fulfilled if we have the preimage stored. The preimage will not
be released before the the payment hash gets removed from
dont_settle_htlcs. Htlcs can still get expired as usual or failed if no
preimage is known.
This is only used by Just-in-time channel openings.
Registering a payment hash in dont_expire_htlcs allows to overwrite the
minimum final cltv delta value after which htlcs would usually get
expired. This allows to delay expiry of htlcs or, if the value in the
dont_settle_htlcs dict is None, completely prevent expiry and let the
htlc get expired onchain.
Splitting this up in two different dicts makes it more explicit and
easier to reason about what they are actually doing.

refactor `htlc_switch` to new architecture to make it more robust
against partial settlement of htlc sets and increase maintainability.
Htlcs are now processed in two steps, first the htlcs are collected into
sets from the channels, and potentially failed on their own already.
Then a second loop iterates over the htlc sets and finalizes only on
whole sets.

Feerate is passed to `Commands._get_fee_policy()` as str which then
tried to multiply the string by 1000. Now it first casts the string to
`Decimal` and multiplies the decimal.

..also export preimage in check_hold_invoice return value if available.
I intentionally did not return the preimage in the returned dict of
wallet.export_requests as this seems risky to do considering some users
of the cli might forward the response to a payer and the payserver
exposes it too.
Closes https://github.com/spesmilo/electrum/issues/10176
Renames RecvMPPResolution.ACCEPTED to .COMPLETE as .ACCEPTED is somewhat
misleading. Accepted could imply that the preimage for this set has been
revealed or that the set has been settled, however it only means that we
have received the full set (it is complete), but the set still can be
failed (e.g. through cltv timeout) and has not been claimed yet.
'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).

also:
- wallet.get_onchain_history was broken with from_height/to_height args
- "show_fees" param is and was non-existent. fees are always added to output
- MyEncoder(json.JSONEncoder) changed a bit:
- I am pretty sure cutting the last 3 chars was intended to cut off the seconds
- however that was making incorrect assumptions about what datetime.isoformat() returns
- which depends on whether microsecond precision is available or whether an explicit timezone is set
- this now makes it clear that we want minutes-resolution, but still leaves the timezone-ambiguity
Adds a `closest_htlc_expiry_height` value to the `check_hold_invoice` cli command response.
This allows to see the next absolute expiry height of the pending htlcs
of a payment. Note, htlcs will get failed before the actual expiry
height (if block_height + 144 > htlc.cltv_abs).
Adds an additional value to the `check_hold_invoice` cli command: `invoice_amount_sat` which returns the requested amount value of the hold invoice.
Co-authored-by: ghost43 <somber.night@protonmail.com>
the cli command `check_hold_invoice` incorrectly assumes that
`lnworker.is_accepted_mpp(payment_hash)` is true for settled invoices,
however it is not as the received mpp entries will be removed from
the `lnworker.received_mpp_htlcs` shortly after adding the preimage to
lnworker (after the htlcs got removed from the channel).
Also renames `amount_sat` in the `check_hold_invoice` response to
`amount_sat_received` to make it more obvious that this is the currently
received amount instead of the amount the invoice of `payment_hash` has
been created with.
Allowing to create hold invoices just by providing a payment hash
instead of the preimage right from the beginning allows for additional
use cases where the recipient doesn't have access to the preimage when
creating the invoice.
Notably verifymessage and decrypt(message) were silently ignoring trailing garbage
or inserted non-base64 characters present in signatures/ciphertext.
(both the CLI commands and in the GUI)
I think it is much cleaner and preferable to treat such signatures/ciphertext as invalid.
In fact I find it surprising that base64.b64decode(validate=False) is the default.
Perhaps we should create a helper function for it that set validate=True and use that.
This allows plugins to document the commands they add.
The docstring is parsed as a regular expression:
arg:<type>:<name>:<description>\n
Types are defined in commands.arg_types.
Note that this commit removes support for single letter
shortcuts in command options.
If a command is not properly documented, a warning is issued
with print(), because no logger is available at this point.
This is most useful if the user wants to import a significant number of keys,
as every invocation of `importprivkey` results in rewriting the wallet file to disk.
The API of "importprivkey" is left unchanged for the single privkey case.
