In lnd, log messages about channels are generally logged with a
reference to their channel point rather than the short channel id.
Channel point is reorg-resistant and also easier to look up in for
example a block explorer.
In the link however, all log messages are accompanied by short channel
id. This makes it difficult to grep a log for all channel activity. The
PEER message for example which are often crucial to analyse, are logged
with channel points.
This commit modifies the link logging to also use channel points.
We want to make sure we can recover funds from a channel that was force
closed by the local node just before the node needed to be restored. We
add a special test case with specific assertions for that scenario.
Improve 'ErrReservedValueInvalidated' error string to explain that the
error is triggered by a transaction that would deplete funds reserved for
potential future anchor channel closings (via CPFP)
Add hint that further details can be found in the debug log
Update strings in 'lntest/itest/log_error_whitelist.txt' correspondingly
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.
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.
- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC
