Since the tests set a quite high fee rate before the node goes to chain,
the HTLCs wouldn't be economical to sweep at this fee rate.
Pre sweeper handling of the second-level transactions this was not a
problem, since the fees were set when the second-levels were created,
before the fee estimate was increased.
To avoid running into the "server is still starting" error when trying
to close a channel, we first wait for the error to disappear before we
try closing the actual channel.
This commit replaces most of the hard coded 10, 15, 20 and 30 second
timeouts with the default timeout. This should allow darwin users to
successfully run the parallel itests locally as well.
This ensures that the nodes will properly be shutdown even if one fails
to start or any of them fail to connect. Previously the shutdown is
defered only in the event that the setup was successful.
Certain checks were implemented with Errorf, which only logs the
failure. This results in the test harness panicking further down. We go
further ahead and convert all calls in this file to use require.
With the new btcd version we can specify our own listen address
generator function for any btcd nodes. This should reduce flakiness as
the previous way of getting a free port was based on just picking a
random number which lead to conflicts.
We also double the default values for connection retries and timeouts,
effectively waiting up to 4 seconds in total now.
To avoid the "Error outside of test" log and to properly terminate the
test if a sub test fails, we need to correctly invoke them using the
RunTestCase method.
In this commit, we extend the `BuildRoute` method and RPC on the router
sub-server to accept a raw payment address which will be included as
part of an MPP payload for the finla hop. This change actually also
allows users to craft their own MPP paths using BuildRoute+SendToRoute.
Our primary goal however, was to fix some broken itests since we now
require the payAddr to be present for ALL payments other than key send
payments.
In some tests we moved channeld.db to a temp location in order to
"time travel". This commit extends the existing semantics by moving all
files, including embedded etcd db too besides the channeld.db file.
Previously, the verbose output of listsweeps would fail if we did not
find some sweeps in our wallet's listtransactions output. This could be
the case for sweeps that were rbf-ed, so the endpoint would fail. This
commit also updates the listsweeps endpoint to always check against the
wallet, so that we do not return these discarded sweeps that never
confirmed.
This commit adds the icase name to the log filename, to make it simpler
to find problematic tests. Additionally after this commit we'll restart
Alice and Bob (the base harness nodes) before each icase to start with a
clean state.
To make sure the test that takes the longest overall time is always
started first, independent of the number of test tranches we run, we
move it to the beginning of the list. Because that test involves a lot
of waiting, it allows us to play around with the number of tranches more
efficiently.
Updating the fee of the mock estimator _after_ starting carol turned out
to be flaky and could lead to the new fee not being picked up in time
for the force close. That lead to carol not cpfp'ing the force closed
transaction.
This fixes tests that were surfaced as flaky. Usually these tests had
an off-by-one error when mining blocks while waiting for a
CSV-encumbered output.
As a preparation to fix an issue with the mempool wait, we clean up the
multi-hop itests a bit. We fix the formatting, use the require library
for assertions consistently and simplify some of the wait predicates.
Commonly used code is also extracted into functions.
In some cases the router isn't yet fully aware of all newly opened
channels. We need to give it some time to process the updates. Therefore
we add a wait for sending payments to give it a few more changes to
catch up.
This fixes itest flakes that happen when a payment is attempted that
ends up causing a channel closure.
completePaymentRequests() attempts to monitor the open channels after a
payment is attempted in order to identify that payment was actually
dispatched to a remote node before returning.
However, when the payment actually causes a channel closure (for
example, because the receiver sent an incorrect preimage) this logic
fails in that the channel will no longer the found in the list of open
channels. This could cause a flake when there was enough time for the
channel to close before performing the check.
One example of such a flaky test is failing_link.
This fixes the issue by also checking whether the total number of
channels was reduced, which indicates (assuming itest operations are
being executed serially) that one of the attempted payments affected at
least one channel.
