Before this commit, if the remaining change was small enough, then it
was possible for us to generate a non-std funding transaction. This is
an issue as the txn would fail to propagate, meaning funds could
potentially be stuck in limbo if users didn't manually drop their
transaction history.
To avoid this scenario, we won't create a change output that is dusty.
Instead, we'll add these as miner fees.
Fixes#690.
It seems that at some point the installation docs of the
https://github.com/lightninglabs/lightning-dev-site/ was identical to
this file (without page navigation + next steps).
Seems that this commit did not get ported to this repo:

In this PR the info for macaroons and noencryptwallet is copied over
from the above mentioned commit.
In this commit, we add an additional constraint to the RPC
configuration parsing. Before this commit, it was possible to start lnd
with either RPC server listening on an external interface *without*
authentication disabled. After this commit, if a user tries to start
the RPC server listening on an external interface without any sort of
RPC authentication, then the daemon will fail to start up.
In order to reduce high CPU utilization during the initial network view
sync, we slash down the total number of active in-flight jobs that can
be launched.
A recent commit modified the mutex in the server to the read/write. In
order to further reduce contention, we’ll grab the read lock when we’re
examining get set of peers to ignore.
Before this commit, we’d unnecessarily use a write transaction within
the FetchChannelEdgesByOutpoint. This is wasteful as the function only
actually reads items from the database, and doesn’t attempt any
mutations at all.
In this commit, we fix a race condition related to the way we attempt
to query to see if an outpoint has already been spent by the time it’s
registered within the ChainNotifier. If the transaction creating the
outpoint hasn’t made it into the mempool by the time we execute the
GetTxOut call, then we’ll attempt to query for the transaction itself.
In this case, if we query for the transaction, then the block hash
field will be empty as it hasn’t yet made it into a block. Under the
previous logic, we’d then attempt to force a rescan. This is an issue
as the forced rescan will fail since it’ll try to fetch the block hash
of all zeroes.
In this commit, we fix this issue by only entering this “fallback to
rescan” logic iff, the transaction has actually been mined.
Fixes#481.
Prior to this commit, payments stored in the channel DB only kept a
record of the payment hash. This is a problem as the preimage is what
serves as proof of payment and a user should be able to look up this
value in the future (not just immediately after payment).
Instead of storing both the payment hash and the preimage, we store the
preimage only since the hash can be derrived from this using a SHA256.
In the RPC listpayments command, we now give the preimage in addition to
the payment hash.
This commit changes the listinvoices and lookupinvoice endpoints to
avoid collisions when making requests.
We can still retrieve a list of pending invoices with `listinvoices` by
appending the parameter `pending_only=true` to the request URL.
This commit causes the configuration parser to accept the values of
RPCUser, RPCPass, and (for the bitcoind back-end) ZMQPath configured
in lnd.conf or on the command line ONLY when all are specified. It
causes the configuration parser to look in btcd.conf or bitcoin.conf
ONLY when none are specified, and causes an error to be returned when
only some are specified, as users have done so erroneously and the
lack of clear feedback has caused difficulties.
This commit alters the restart logic in the nursery
to load channel close summaries from disk when
restarting the process of sweeping commit txns.
The channel close summary contains a closing height,
which is used to set the lower bound of the height hint
when resubscribing to spend notifications.
This commit adds a FetchClosedChannel method to the
channeldb, which allows querying based on a known
channel point. This will be used in the nursery to
load channel close summaries, which can be used to
provide more accurate height hints when recovering
from failures.
In this commit, we update all the references to
btcwallet+neutrino+gozmq included in the current build. We do this as a
number of bugs related to the bitcoind backend have been fixed.
This commit uses the multimutex.Mutex to esure database
state stays consistent when handling an announcement, by
restricting access to one goroutine per channel ID.
This fixes a bug where the goroutine would read the
database, make some decisions based on what was read,
then write its data to the database, but the read data
would be outdated at this point. For instance, an
AuthProof could have been added between reading the
database and when the decision whether to announce
the channel is made, making it not announce it.
Similarly, when receiving the AuthProof, the edge
policy could be added between reading the edge state
and adding the proof to the database, also resulting
in the edge not being announced.
This commit fixes a bug that could cause annoucements
to get lost, and resultet in flaky integration tests.
After a set of announcements was broadcastet, we would
reset (clear) the announcement batch, making any
annoucement that was added between the call to Emit()
and Reset() to be deleted, without ever being broadcast.
We can just remove the Reset() call, as the batch will
actually be reset within the call to Emit(), making
the previous call only delete those messages we hadn't
sent yet.
