In this commit, we convert the delivery address in the open and accept
channel methods to be a TLV type. This works as an "empty" delivery
address is encoded using a two zero bytes (uint16 length zero), and a
tlv type of 0 is encoded in the same manner (byte for type, byte for
zero length). This change allows us to easily extend these messages in
the future, in a uniform manner.
When decoding the message we snip the bytes from the read TLV data.
Similarly, when encoding we concatenate the TLV record for the shutdown
script with the rest of the TLV data.

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 create a new `ExtraOpaqueData` based on the field
with the same name that's present in all the announcement related
messages. In later commits, we'll embed this new type in each message,
so we'll have a generic way to add/parse TLV extensions from messages.
In order to prep for allowing TLV extensions for the `ReplyChannelRange`
and `QueryChannelRange` messages, we'll need to remove the struct
embedding as is. If we don't remove this, then we'll attempt to decode
TLV extensions from both the embedded and outer struct.
All relevant call sites have been updated to reflect this minor change.
In this commit, we migrate all wire messages in the database from the
`legacy` to the `current` encoding.
This affects the way we write the `CommitDiff` and `LogUpdates` struct
to disk. We also need to migrate the network results bucket in the
switch as it includes a wire message without a length prefix.
We copy the new serialization togic to a new package 'current' and
export the methods we will need from the migration. This ensures that we
have isolation between the legacy and current serialization methods,
cleanly inidcating what type we are using during the migration.
In this commit, we modify the way we write wire messages across the
entire database. We'll now ensure that we always write wire messages
with a length prefix. We update the `codec.go` file to always write a 2
byte length prefix, this affects the way we write the `CommitDiff` and
`LogUpdates` struct to disk, and the network results bucket in the
switch as it includes a wire message.
The legacy encoding depends on the lnwire21 version of lnwire, so it will
let us change lnwire after the migration. To make sure it is separated
from the new encoding, we add it to a new package 'legacy'.
We also put common types in a new package 'common', which will house
types that won't change during the migration, and can be used by both
legacy and current serialization code.
If a channel was manually disabled, subsequent automatic / background
requests to update that channel's state will be ignored. A RequestAuto
call restores automatic / background state management and indicates
that such requests should no longer be ignored.
Add boolean parameter for test functions without changing any
existing functionality. All current tests set manual = false, but
Future tests can set manual = true to test manual requests to
update channel state.
Add a new boolean parameter without changing any existing
functionality. The parameter will be used to indicate
whether a request to update a channel's status was made
manually by a user (currently always false).
To avoid code changing underneath the static migrations, we copy the
lnwire dependency in its current form into the migration directory.
Ideally the migrations doesn't depend on any code that might change,
this takes us a step closer.
This produces a race condition when reading AssumeChannelValid from a
different goroutine. Instead we isolate the test cases and initial
AssumeChannelValid properly.
This commit reduces the number of concurrent validation operations the
router will perform when fully validating the channel graph. Reports
from several users indicate that GetInfo would hang for several minutes,
which is believed to be caused by attempting to validate massive amounts
of channels in parallel. This commit returns the limit back to its
original state before adding the batched gossip improvements.
We keep the 1000 concurrent validation request limit for
AssumeChannelValid, since we don't fetch blocks in that case. This
allows us to still keep the performance benefits on mobile/low-resource
devices.
The shasum command isn't available in Alpine linux while the sha256sum
command isn't available on MacOS. We add a simple switch that tries to
detect which one is available.
To fix an issue where the golang version would be picked up from the
host system if the docker-release command was used, we switch over to
using make inside of the container as well instead of feeding the
parameters into the release script manually.
We only pass in the flags that we might actually want to overwrite.
