In this commit, we modify the sphinx replay test to actually force close
that final channel. We do this, as otherwise, we'll now reject the co-op
close attempt as the channel still has active HTLCs.
In this commit, we follow up to the prior commit by ensuring we won't
accept a co-op close request for a chennel with active HTLCs. When
creating a chanCloser for the first time, we'll check the set of HTLC's
and reject a request (by sending a wire error) if the target channel
still as active HTLC's.
In this commit, we fix a bug that at times could cause any dangling
HTLC's to be sent to miner's fees if a user attempted to close out a
channel cooperatively that still had pending HTLC's. We'll first prevent
this at the RPC level by rejecting any attempts to trigger a co-op
channel closure while a channel still have dangling HTLC's.
In this commit, we fix a logic error in our routine for converting a
uint64 to/from base32. Before this commit, we assumed that the max
number of groups was 12. However, the math.MaxUint64 (1<<64 - 1) can
actually consume more than 12 groups with an extra set of bits. Before
this commit, we would panic when attempting to parse an invoice
generated like so:
* addinvoice --amt 1337000 --expiry 99999999999999999
To fix this issue, we modify our logic to expect at most 13 groups.
Additionally, we've added a new test that would panic before applying
this commit.
Fixes#972.
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.
