In the process, we also move the feature serialization into the
invoicesrpc package, so that it can be shared between the invoicesrpc
and main rpcserver.
Previously if a payment was sent with custom records attached, path
finding wouldn't perform a check whether the final node was capable of
receiving custom records in a tlv payload.
This commit prepares for more manipulation of custom records. A list of
tlv.Record types is more difficult to use than the more basic
map[uint64][]byte.
Furthermore fields and variables are renamed to make them more
consistent.
Before we change the Hop struct, isolate the code that is used in older
migrations to prevent breaking them.
route.go was taken from commit 6e463c1634061d595953f20813860207e5d485ce
To allow signing of messages with any key in the key chain
we add two new methods to the signer RPC. These behave differently
to the methods with the same name in the main RPC as described
in the documentation comment.
This commit introduces PriorityQueue, which is a general, heap
based priority queue, and PriorityQueueItem which is an interface
that concrete priority queue items must implement.
This implementation is encapsulated, users do not need to use any
other package for full functionality.
PriorityQueue exports the usual public methids: Push, Pop, Top,
Empty and Len. For full documentaton consult the priority_queue.go,
for usage: priority_queue_test.go
In this commit we fix in a bug in `lnd` that could cause other
implementations which implement a strict version of the spec to
disconnect when trying to sync their channel graph using the gossip
query feature. Before this commit, we would embed the request to a
`QueryChannelRange` in the response, causing some clients to reject the
response as the `FirstBlockHeight` and `NumBlocks` field would be
identical for each chunk of the response.
In order to remedy this, we now properly set these two fields with each
returned chunk. Note that even after this commit, we keep our existing
behavior surrounding the `Complete` field as is. Otherwise, current
`lnd` clients which rely on this field (rather than the two
aforementioned fields) wouldn't be able to properly detect when a set of
responses to their query was "complete".
Partially fixes#3728.
