This commit adds each channel's short chan id to the `feereport` rpc.
Without this, it can be tedious to lookup more info about a particular
channel since most rpcs only accept short chan ids and not channel
points. For instance, now one can take a channel id from `feereport` and
look it up directly via `getchaninfo` to examine the policy in more
detail.
This commit corrects a bug in TxWeightEstimator that could result in
underestimations for transactions involving NestedP2WPKH and NestedP2WSH
inputs. The scriptSig data push is now accounted for in a proper size
constant, and the input count is now incremented in both. This would
only be detectable in the event that the number of non-nested inputs and
the total number of inputs straddle the discontinuities in the
CompactSize encoding, e.g. 253, 2^16-1, or 2^32-1.
This commit modifies the NP2WKH and NP2WSH input tests to ensure the
input count is properly incremented and accounted for in the size
estimate. 253 is chosen because it is the lowest value that, when
serialized, occupies more than one byte on the wire.
The synchronous call to get all channel backups also include
channels that are pending at the moment of the call. A previous
commit added pending channels to the file based backup as well. So
this is the last backup method that needs to be adjusted to also
contain unconfirmed channels.
To fix the discrepancy between getting the channel backups via
RPC where all pending channels are included, we also update the
channel.backup file on disk whenever we get a pending channel
event notification.
This fixes a race during channel closing, where the last channel state
update was still not finished when we set the channel close bit in the
database. This lead to a flake during integration tests, where the last
state update would not finish, and the channel wasn't closes
successfully.
We fix it by first unregistering the channel, making sure it is removed
fully from the link before doing the db modification.
This commit renames the `reversed` pagination flag to
`paginate-forwards`, which is off by default. In order to
access older invoices one can set the paginate-forwards flag,
which is more intuitive than setting the reversed flag to false.
Update channel updates and subscription itest to check that close
initiator is appropriately set for cooperative and force closes for the
local and remote party.
Add an initiator enum which allows up to display an unknown value for
channels that are not in the historical chan bucket, rather than having
and ambiguous false value also representing no-value. A both option is
added to cover the case where both parties initiated a close on chain.
Add an optional channel status CloseChannel which will be stored on the
hitsorical channel which is persisted at channel close. This status is
used to set the close initiator for channels that do not complete the
funding flow or we abandon. In follow up commits, this status will be
used to record force and breach closes. The value is written to the
historical channel bucket for diplay over rpc.
This commit adds two new channel statuses which indicate the party that
initatited closing the channel. These statuses are set in conjunction
with the existing commit broadcast status so that we do not need to
migrate existing logic to handle multiple types of closes. This status
is set for locally initiated force closes in this commit because they
follow a similar pattern to cooparative closes, marking the commitment
broadcast then proceeding with tx broadcast. Remote force closes are
added in the following commit, as they are handled differently.
By default, Travis-CI does `git clone --depth=50` which limits the
repo to the last 50 commits. Because we do linting against an old
commit, it cannot be found any more. We remove the limit completely
to not run into this problem again.
This commit adds link failure notifications for failures which occur
on our incoming link. These failures may be receives which we failed or
forwards which we could not parse.
Add notifications for local initiated sends settles and forwarding
failures. As with link failures, local send settles and forwarding
failures are reported directly to the router so must have their own
notification handling.
Notify link failures for our own payments. Separate handling code is
required for local payment link failures because we do not pass these
failures back through the switch (like we do for link failures for
forwards), but rather send them straight back to the router. Our own
sends have the payment ID saved in the incoming htlc ID of the packet's
incoming circuit. This change replaces that value with for the sake
of consistent notifying of sends and receives from our node.
This commit adds notifications for htlcs which are forwarded through
our node. Forwards are notified when the htlc is added on our ougoing
link, settles when we send a settle message to the downstream peer.
If a failure occurs, we check whether it occurred at our node, then
notify a link or forwarding failure accordingly.
Note that this change also adds forward event notifications for sends
which are initiated by our node because the handling code for adding
a htlc which originates from our node is the same as that for handling
forwards. Htlcs for our locally initiated sends have our internal pid
set in the incoming htlcs id field, so we extract this value and notify
with a zero htlc id to be consistent with receives (which have zero
outgoing circuits). Subsequent settles or failures are not noitfied
for local sends in this commit, and will be handled in a follow up.
This commit sets more fields on the htlcPacket created to fail adding
a htlc packet to the switch for notification purposes. This new data is
copied by value from the original packet. The packet is then failed
back to the peer that forwarded us the packet, which is handled by
handledownstream packet. The values added to the packet are not used
in the handling of a failed packet.
