In this commit, we address a bug where it's possible that we still
attempt to manually scan for a transaction to determine whether it's
been included in the chain even after successfully checking the txindex
and not finding it there. Now, we'll short-circuit this process by
exiting early if the txindex lookup was successful but the transaction
in question was not found. Otherwise, we'll fall back to the manual
scan.
In this commit, we extract some of the helper test variables and
functions into their own file and guard them under a build flag. This is
needed as some unit tests will be introduced in a future commit where
most of the same functions within the interface tests are reused. In
order to prevent these variables and functions from being exportable, we
guard them by the "debug" build tag.
Adds a new external signal alerting autopilot that
new nodes have been added to the channel graph or
an existing node has modified its channel
announcment. This allows autopilot to examine its
current state, and attempt to open channels if our
target state is not yet met.
In this commit, we ensure that we're able to properly parse the cert and
macaroon paths for all relevant config variants. Before this commit, it
would be the case that the macaroon path ended up empty if a user wasn't
running the default (mainnet, lnddir) settings. In this commit, we
remedy this by parsing each of the two (cert+macaroon) paths
independently.
This commit fixes a bug that would cause us to fetch our peer's
ChannelUpdate in some cases, where we really wanted to fetch our own.
The reason this happened was that we passed the peer's pubkey to
fetchLastChanUpdate, making us match on their policy. This would lead to
ChannelUpdates being sent during routing which would have no effect on
the attempted path.
We fix this by always use our own pubkey in fetchLastChanUpdate, and
also uses the common methods within the server to be able to extract the
update even when only one policy is known.
This commit fixes a bug within the peer, where we would always use the
default forwarding policy when adding new links to the switch. Mostly
this wasn't a problem, as we most often are using default values for new
channels, but the min_htlc value is a value that is set by the remote,
not us.
If the remote specified a custom min_htlc during channel creation, we
would still use our DefaultMinHtlc value when first adding the link,
making us try to forward HTLCs that would be rejected by the remote.
We fix this by getting the required min_htlc value from the channel
state machine, and setting this for the link's forwarding policy.
Note that on restarts we will query the database for our latest
ChannelEdgePolicy, and use that to craft the forwardingPolicy. This
means that the value will be set correctly if the policy is found in the
database.
This commit fixes a bug that would make us advertise the remote's
min_htlc value in our channel update.
The min_htlc value is set by a node Alice to limit its exposure to small
HTLCs, and the channel counter party should not forward HTLCs of value
smaller than this to Alice. This means that the value a node Bob should
advertise in its ChannelUpdate, is the min_htlc value the counter party
require all HTLCs to be above.
Instead of populating the ChannelUpdate with the MinHtlc value found in
the remote constraints, we now use the value from the local constraints.
