This commit make the fundingmanager tests poll for database state
for a time, instead of using an explicit sleep before accessing the
DB. This should address some of the flakes encountered on Travis,
where db writes might take longer than usual.
This commit cleans the fundingManager tests by extracting
most of the common code from the different test cases into
assert methods, making the test cases easier to follow
and distinguish.
It also adds a new test for the case where the peer goes
offline, and the fundingManager must wait for it to come
online before it can send the fundingLocked message and
continue the funding flow.
This commit adds a channel barrier on fundingManager startup for
channels where the opening process is not finished. This fixes
a bug where we after restarting the fundingManager would receive
the fundingLocked message, and crash when trying to close the
non-existing barrier.
In case we received a fundingLocked message after our own opening
process was finished, we would crash with the same error. We
therefore check if the channel barrier exists before we try to
close it.
It also adds functionality to fundingManager that makes it
ignore a fundingLocked message it receives for a channel where
this is already received. This is necessary when we in case of
a reconnection resend the fundingLocked since we cannot be sure
the remote has received it.
The fundingmanager tests are also updated to check that the
fundingLocked messages are sent and handled correcly, and also
exercise the scanarios described above.
This commit adds the fee negotiation procedure performed
on channel shutdown. The current algorithm picks an ideal
a fee based on the FeeEstimator and commit weigth, then
accepts the remote's fee if it is at most 50%-200% away
from the ideal. The fee negotiation procedure is similar
both as sender and receiver of the initial shutdown
message, and this commit also make both sides use the
same code path for handling these messages.
This commit adds the +build !rpctest build flag to the test files in
the main package other than the RPC tests. With this, if the protest
build flag is set, then ONLY those tests will be run.
Persists the state of a channel opening process after funding
transaction is confirmed. This tracks the messages sent to
the peer such that the process can be continued in case of a
restart. Also introduces that the receiver side forgets about
channel if funding transaction is not confirmed in 48hrs.
