This commit refactored the function NewNode to take a *testing.T so that
the unexpected error is checked inside it. The caller is now free from
checking the errors.
This permits an AMP invoice to be "pseudo-reusable", where the invoice
paramters can be used multiple times so long as a new payment address is
supplied. This prevents additional round trips between payer and payee
to obtain a new invoice, even though the payments/invoices won't be
logically associated via the RPC interface like they would when the full
reusable invoices are deployed.
In some rare instances it can happen that the nodes don't find each
other again after one of them has been re-created and the other one has
been restarted in the SCB tests. By making sure the re-created has the
same P2P port again as before, we make sure they can connect to each
other again successfully for executing DLP.
Since there is a lot of connecting and disconnecting between nodes in
the channel backup tests, we try to speed up that process by lowering
the min backoff from 1 second to 50 milliseconds. We also make sure we
never wait more than 1 second if it does take multple attempts. This
should sum up and hopefully speed up our tests a bit.
This commit adds a new "waiting to start" state which may be used to
query if we're still waiting to become the cluster leader. Once leader
we advance the state to "wallet not exist" or "wallet locked" given
wallet availablity.
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.
