This commit changes the shouldGoOnChain signature to get the htlc
as parameter. I will allow the function to take decisions based on
whether the htlc is Incoming or Outgoing.
Add a CheckCircularForward function which detects packets which are
forwards over the same incoming and outgoing link, and errors if the
node is configured to disallow forwards of this nature. This check is
added to increase the cost of a liquidity lockup attack, because it
increases the length of the route required to lock up an individual
node's bandwidth. Since nodes are currently limited to 20 hops,
increasing the length of the route needed to lock up capital increases
the number of malicious payments an attacker will have to route, which
increases the capital requirement of the attack overall.
This change instructs the REST proxy server to overwrite its default
JSON marshaler settings. That allows us to set EmitDefaults to true
which will result in all JSON fields returned in REST responses to
be fully populated, even if their values are falsey.
This commit intends to fix slow first startup time when there are many
invoices that need to be canceled. The slowdown is caused by a combination
of adding invoices to the expiry watcher one-by-one and slow
cancellation. Due to slow cancellation and the unbuffered channel which
we use to pass invoices to the expiry watcher blocks the registry.
With this fix we'll instead batch add invoices to the expiry watcher and
thereby won't block the registry startup.
This commit adds PendingOpenChannel to SubscribeChannelEvents stream in
the gRPC API.
This is useful for keeping track of channel openings that Autopilot does.
It can also be used for the non-initator side of a channel opening to keep
track of channel openings.
In this commit, we change the release script slightly to return the
latest tag if there're multiple tags at head. Otherwise the release
script will fail if our final tag is at the same commit as the prior
release candidate tag.
Returning from the sendPayments method closes the underlying stream, so
we would risk payments still being in flight when returning.
We add the running goroutines to a waitgroup, such that we can wait for
them all to exit before exiting and closing the stream.
In case an error is encountered in the process, we will return directly,
which will close the `reqQuit` channel and prompt the gorpoutines to
shut down.
