Since we want to support AMP payment using a different unique payment
identifier (AMP payments don't go to one specific hash), we change the
nomenclature to be Identifier instead of PaymentHash.
Our aggregate htlc test depends on our previous behavior
where recipients would allow channels with pending hold
invoice htlcs to force close. Now that we have an expiry
watcher to prevent these force closes, we can't rely on
this for tests because the recipient will cancel the htlcs
back before they expire.
This commit adds a test for a hold invoice which is accepted
off-chain, and held by the recipient until it expired and
the payer force-closes the channel. With this test we
demonstrate two bugs in our handling of hold invoice state
in the invoice registry when we expire on chain:
- Htlcs not updated: even when we've timed out, we don't
update the htlc state accordingly.
- Invoice can be settled: the invoice can be settled even
though it's expired on chain.
Reproduce the case where we allow settling of invoices that have
htlcs that have actually timed out on chain. This bug can rarely
occur if a hodl invoice goes to chain and is manually settled
after it has timed out. Funds are SAFU, but this could be a
headache because the invoice says it's settled when no funds
were claimed.
This commit updates our multi-hop force close test to use a hodl
invoice so that we can reproduce some bugs which will require
the preimage for the invoice that is timed out on chain.
This commit deprecates/replaces the old field `sat_per_byte` with
`sat_per_vbyte`. While the old field suggests sat per byte, it’s
actually using sat per virtual byte. We use the Hidden param to hide all
the deprecated flags. These flags won't show up in help menu onwards,
while stay valid that can be passed from cli. Thus bash scripts
referencing these fields won't be broken.
This commit makes us gate the calls to the RPC servers according to the
current RPC state. This ensures we won't try to call the RPC server
before it has been fully initialized, and that we won't call the
walletUnlocker after the wallet already has been unlocked.
We also test that legacy keysend payments are promoted to AMP payments
on the receiver-sdie by asserting basic properties of the fields
returned via the rpc.
