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.
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.

lnwire: update quickcheck tests, use constant for Error
multi: update unit tests to pass deep equal assertions with messages
In this commit, we update a series of unit tests in the code base to now
pass due to the new wire message encode/decode logic. In many instances,
we'll now manually set the extra bytes to an empty byte slice to avoid
comparisons that fail due to one message having an empty byte slice and
the other having a nil pointer.
In this commit, we ensure that when we read node aliases from the wire,
we ensure that they're valid. Before this commit, we would read the raw
bytes without checking for validity which could result in us writing in
invalid node alias to disk. We've fixed this, and also updated the
quickcheck tests to generate valid strings.
In this commit, we export the ReadElements and WriteElements functions.
We do this as exporting these functions makes it possible for outside
packages to define serializations which use the BOLT 1.0 wire format.
In this commit, we add a new field to all the existing gossip messages:
ExtraOpqueData. We do this, as before this commit, if we came across a
ChannelUpdate message with a set of optional fields, then we wouldn't be
able to properly parse the signatures related to the message. If we
never corrected this behavior, then we would violate the forwards
compatible principle we use when parsing existing messages.
As these messages can now be padded out to the max message size, we've
increased the MaxPayloadLength value for all of these messages.
Fixes#1814.
In this commit, we replace all instances of *btcec.PublicKey within the
announcement messages with a simple [33]byte. We do this as usually we
don’t need to immediately validate an announcement, therefore we can
avoid the scalar multiplications during decoding.
This commit alters the NodeAlias String method to trim null-bytes from
the end of the alias. This is helpful for presentation in contexts such
as the GetInfo response.
This commit modifies the NodeAnnouncement message to ensure that it
matches the current spec ordering. The spec was recently modified to
place the feature vector first to allow for future changes to the
fields to be forwards compatible.
This commit fixes a deviant in the way we serialize and deserialize the
node announcement message from that which is currently in the spec.
Before this commit we reversed the order of features and addresses.
Instead, on the wire, features should come _before_ the addresses.
We also add a new temporary feature bit to ensure nodes that don’t
directly connect to each other if they don’t have this new update.
However, this will also partition any current tests nets when new nodes
join them as the digest signed has changed, therefore invalidating any
older messages.
Fixes#207.
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.
This commit modifies address handling in the NodeAnnouncement struct,
switching from net.TCPAddr to []net.Addr. This enables more flexible
address handling with multiple types and multiple addresses for each
node. This commit addresses the first part of issue #131 .
This commit modifies the ChannelUpdateAnnouncement to rename the Expiry
variable instead of TimeLockDelta as that is more descriptive of the
purpose of the attribute itself.
This commit modifies the login of sent/recv’d wire messages in trace
mode in order utilize the more detailed, and automatically generated
logging statements using pure spew.Sdump.
In order to avoid the spammy messages due to spew printing the
btcec.S256() curve paramter within wire messages with public keys, we
introduce a new logging function to unset the curve paramter to it
isn’t printed in its entirety. To insure we don’t run into any panics
as a result of a nil pointer defense, we now copy the public keys
during the funding process so we don’t run into a panic due to
modifying a pointer to the same object.
This commit makes a large number of minor changes concerning API usage
within the deamon to match the latest version on the upstream btcsuite
libraries.
The major changes are the switch from wire.ShaHash to chainhash.Hash,
and that wire.NewMsgTx() now takes a paramter indicating the version of
the transaction to be created.
This commit modifies the Alias type to only hold the non-zero portion
of the alias as encoded on the wire. Previously the entire 32-bytes
would be read and stored, including the zeroes at the end used as
padding. Within the constructor, we now parse the alias properly,
discarding the trailing zeroes within the passed byte slice.
Additionally, the .String() method of Alias will now also only print
the non-zero prefix of the decoded alias.
This commit temporarily disables the signature validation for all
announcement related messages which should be authenticated by one or
many parties. This feature is being disabled as we don’t yet generate
valid signatures for our advertisements and the validation of the
messages should be placed in the layer 3 discovery service rather than
within within the message parsing layer.
This commit separates out the ChannelID into a new file, with
additional helper methods for conversion and formatting. With this
commit, the struct is now more general purpose and can be used in the
new routing package, database, and other related sub-systems.
