Before this commit, both writing and reading an encoded empty set of short channel IDs from the wire would fail. Prior to this commit, we treated decoding an empty set as a caller error, and failed to write out the zlib encoding of an empty set in a way that us and the other implementations were able to read. To fix this, rather than giving zlib an empty buffer to write out (which results in an encoding with the zlib header data and the rest), we just write a blank slice. When decoding, if we have an empty query body, then we'll return a `nil` slice. With the above changes, we'll now always write out an empty short channel ID set as: ``` 0001 (1 byte follows) || <encoding_type> ``` A new test has also been added to exercise this case for both known encoding types.
lnwire
The lnwire package implements the Lightning Network wire protocol.
This package has intentionally been designed so it can be used as a standalone package for any projects needing to interface with lightning peers at the wire protocol level.
