This commit mitigates a problem within the ChannelArbitrator, where
after a restart we would start up in the state StateBroadcastCommit but
fail to broadcast out commitment because a conflicting transaction (most
likely our own commitment) was already broadcast. A more complete fix
for this case will be added later, but this commit let the
ChannelArbitrator continue, trying to close out the channel.
This commit continues the work started by @sp4ke, in createing
a simple Makefile for lnd. The following commands are included:
* make - builds everything (deps, lnd, and lncli) from scratch
* make deps - installs dep if needed, then runs dep ensure
* make install - builds lnd and lncli
* make check - runs unit and itests
* make unit - runs the unit tests for all packages
* make itest - installs lnd and runs integration tests
* make fmt - go fmt's all files
When in neutrino mode, it seems that the node is not closed during the cleanup, so if a block is received between the time the DB is closed and the server is closed (or if the process is still running after the server is shutdown like on a mobile app), the code panic's and crashes with:
panic: unable to write block header: database not open

This commit moves the call to the bitcoind backend to start watching an
outpoint for spentness to after we have recorded the outpoint in our
list of clients. This is done to avoid a race that we saw using the btcd
backend, and it is probable that it can also happen using bitcoind.
This commit moves the call to the btcd backend to start watching an
outpoint for spentness to after we have recorded the outpoint in our
list of clients. This is done to avoid a race that could occur if btcd
quicly sent a spend notification before we had been able to record it in
our map, essentially losing it.
Modifies TestFetchPendingChannels to verify that calls to
MarkAsOpen also modify the in-memory state. Previously we
only tested the persistent state loaded immediately after.
Modifies the MarkAsOpen operation to also update the
ShortChanID and IsPending fields in-memory. Before,
only the on-disk representation was updated, which
may have lead to stale data channel states being
passed in-memory.
In this commit, we add an additional check within CreateCommitTx to
ensure that we will never create or accept a commitment transaction that
wasn't valid by consensus. To enforce this check, we use the
blockchain.CheckTransactionSanity method.
This commit is a follow up to the prior commit which fixed a rounding
error bug in lnwallet. For uniformity, we also fix other occurrences in
the breach arbiter, as well as the integration tests.
In this commit, we fix an existing rounding related bug in the codebase.
The RPC interface for btcd and bitcoind return values in BTC rather than
in satoshis. So in several places, we're forced to convert ourselves
manually. The existing logic attempted to do this, but didn't properly
account for rounding. As a result, our values can be off due to not
rounding incorrectly.
The fix for this is easy: simply properly use btcutil.NewAmount
everywhere which does rounding properly.
Fixes#939.
In this commit, we update our set of dependencies to a new version of
our zmq lib that implements automatic reconnection. With this change,
bitcoind users will have a more robust experience, as if the connection
is dropped, we'll reconnect automatically.
Fixes#875.
Fixes#871.
Fixes#857.
Fixed formatting for autopilot config params, as well as added check for
`MaxChannels` param which was presumably a mistaken copypaste from the
`MaxChannelSize' param.
In this commit, we add a new node to the current default test graph
that we use for our path finding tests. This new node connects roasbeef
to sophon via a new route with very high fees. With this new node and
the two channels it adds, we can properly test that we’ll route around
failures that we run into during payment routing.
In this commit, we add vertex pruning for any non-final CLTV error.
Before this commit, we assumed that any source of this error was due to
the local node setting the incorrect time lock. However, it’s been
recently noticed on main net that there’re a set of nodes that seem to
not be properly scanned to the chain. Without this patch, users aren’t
able to route successfully as atm, we’ll stop all path finding attempts
if we encounter this.
