This commit extends the kvdb interface in a backwards compatible way
such that we'll be able to prefetch all keys in a bucket in one go reducing the
number of roundtrips.
This commit adds more full range caching to the STM such that we'll
be able to prefetch keys and ranges on the kvdb level. This will allow
us to reduce roundtrips to etcd do fast iteration of small ranges.
Fixes an issue where an out of order block error occurs in the router. When this occurs, the change uses the chain notifier to catch up on missed blocks and uses those blocks to fully update the routing graph with closed channels. Fixes#4710, #5132
Adds a new Brontide struct method tryLinkShutdown that attempts to
fetch the target link and calls ShutdownIfChannelClean on it. This
allows the coop close process to guarantee atomicity of the underlying
channel state. Also removes the UnregisterChannel method from the
chancloser's config as the link is shut down before the chancloser
is created.
This allows a caller to ensure to optimistically shut down the link
if the channel is clean. If the channel is not clean, an error is
returned and the link continues functioning as normal. The caller
should also call RemoveLink to ensure that the link isn't seen as
usable within the switch.
Adds a method to the LightningChannel struct called IsChannelClean
that returns a boolean telling the caller whether the channel state
is clean or not. Clean in this case means there are no lingering
updates to be signed for, no HTLC's active on either sides commitment
transaction, and no pending commitments on either side. This can be
used for dynamic commitments or during a strict cooperative close
process that ensures atomicity of the channel.
The RPC DeletePayment allows deleteing single payment from its ID. When calling with `FailedHtlcsOnly` set in the request only failed HTLCs of this payment will be deleted.
Adds `DeletePayment` to the channeldb, which allows to delete a single payment. If only failed HTLCs for this payment should be deleted it can be specified by the bool `failedHtlcsOnly`.
In this commit we add an extra config for enabling logging to an
external file when using embedded etcd. This can be useful when running
integration tests to see more details about etcd related issues.
This PR changes a link in the section Developer Resources from dev.lightning.community (unmaintained) to docs.lightning.engineering.
It also specifies more clearly what readers can expect to find there.
selectHopHints is the function which constructs hophints otherwise found
in an invoice created with the private flag.
In this commit, we expose that functionality a little more to workaround
needing to create an invoice to retrieve routing hints. Of course, this
is not a perfect solution as the functionality is exposed exclusively to
go users.
