In preparation for adding the new ChannelAnnouncement2 message along
with a ChannelAnnouncement interface, we rename the existing message to
ChannelAnnouncement1.
In preparation for adding a new message, AnnounceSignatures2 along with
an AnnounceSignatures interface, we rename the existing message to
AnnounceSignatures1.
The purpose of this interface is to distinguish messages that are
bound to a particular channel_id from those that are not. There is
no reason this ought to be a property of the peer package as it is
entirely determined by the contents of the message itself. Therefore
we move it to the lnwire package so it can be used without having
import cycles elsewhere in the codebase.
These two messages will be used to implement the new and improved co-op
closing protocol. This PR also show cases how to use the new
`tlv.OptionalRecord` type to define and handle TLV level parsing.
I think we can make one additional helper function to clean up some of
the boiler plate for the encode/decode.
Add the ability to specify messages < CustomRangeStart that will still
be treated like custom messages by lnd (rather than unknown ones). This
allows code external to lnd to handle protocol messages that are *not
yet known to lnd*.
This commit adds Warning messages to lnwire, as introduced in bolts/950.
It does not include reading/writing of warning messages, which will be
covered in followup commits.
This commit changes the WriteElement and WriteElements methods to take a
write buffer instead of io.Writer. The corresponding Encode methods are
changed to use the write buffer.
This commit changes the method WriteMessage to use bytes.Buffer to save
heap allocations. A unit test is added to check the method is
implemented as expected.
Removes the MaxPayloadLength function from the Message interface
and checks that each message payload is not greater than MaxMsgBody.
Since all messages are now allowed to be 65535 bytes in size, the
MaxPayloadLength is no longer needed.
In this commit we correct an off by one error on the Shutdown and
ClosingSigned message types. Additionally, we fix an error related to
the numbering of the UpdateFee message. With this we, gain proper
compatibility with the other implementations when it comes to
commitment hygiene, and also the cooperative closure process.
Early in the lifetime of the project here were a few files we either
copied entirely, or used as the basis for code within lnd. Before this
PR, this was not recognized by retaining the original copyright. With
this commit, we remedy that by explicitly noting the copyright in the
relevant files.
Fixes#423.
In this commit the reestablish message have been added, which serves as
channel state synchronization message. Before exchanging the messages
for particular channel peers have to send it to each other as the
first message in order to be sure that non of the updates have been
lost because of the previous disconnect.
In this commit BOLT#4 specification message have been added to the
lnwire package. This messsage is needed in order to notify payment
sender that forwarding node unable to parse the onion blob.
In this commit onion routing error from BOLT#4 have been added, the
initial error construction have been splitted on two parts: The first
part which contains the actual data will reside inside the lnwire
package because it contains all necessary function to decode/encode
the data. The second part obfuscation and hmac checking will resides
inside the lighting-onion package because it requires the key
generation.
This commit modifies ReadMessage to no longer return the total bytes
read as this value will now be calculated at a higher level. The
io.Reader that’s passed to ReadMessage is expected to contain the
_entire_ message rather than be a pointer into a stream that contains
the message itself.
This commit abandons our old bitcoin inspired message header and
replaces it with the bare type-only message headers that’s currently
used within the draft specification. As a result the message header now
consists of only 2-bytes for the message type, then actual payload
itself. With this change, the daemon will now need to switch to a
purely message based wire protocol in order to be able to handle the
extra data that can be extended to arbitrary messages.
This commit modifies the Message interface to convert the Command
method to a MsgType method that uses a new set of message type for all
the defined messages. These new messages types nearly exactly match the
message types used within the current draft of the BOLT specifications.
This commit revues the Validate method from the Message interface as
the method is no longer used and is a relic from an older version of
the codebase.
Change the name of fields of messages which are belong to the discovery
subsystem in a such way so they were the same with the names that are
defined in the specification.
In this commit announcement signature message has been added which is
needed when peers want to announce their channel to the rest of the
network. This message acts as half proof carrier, nodes exchanges
their half proofs with each other and after that they are able to
construct the full proof.
When the funding transaction has been confirmed, the FundingLocked
message is sent by the peers to each other so that the existence of the
newly funded channel can be announced to the network.
This commit also removes the SingleFundingOpenProof message.
