According to install.md, the minimum version of Go supported at the
moment is 1.9, so update the Go version referenced in Contribution
Checklist to 1.9 as well.
Now that we have a fallback method for when the transaction index is not
enabled, its requirement to be enabled for a full node is no longer
needed, so we can safely remove this check.
Before this commit, we relied on the need of full nodes to enable the
transaction index. This allowed us to fetch historical details about
transactions in order to register and dispatch confirmation and spend
notifications.
This commit allows us to drop that requirement by providing a fallback
method to use when the transaction index is not enabled. This fallback
method relies on manually scanning blocks for the transactions
requested, starting from the earliest height the transactions could have
been included in, to the current height in the chain.
This commit extends the test to exercise a scanario that wasn't properly
covered, by registering for a confirmed spend notification for a
historical spend. We also extend the test to make sure it handles buried
spends properly.
This commit fixes a recently introduced bug in the btcdnotifier, where
we would skip all spend clients waiting for a confirmed spend in
txUpdates. The regular case where a spend is included in a new block was
correctly handled in onBlockConnected, but the txUpdates queue is also
used for confirmed spends during rescans, which we would miss. This
commit fixes that by checking if the tx update is confirmed or
unconfirmed, and acts accordingly.
This commit fixes a bug where all the HTLC rhash slices in a
ListChannelsResponse would be tied to the loop variable, making them all
take the hash of the last HTLC in the list. This commit fixes it by
making a copy of the slice.
In this commit, we fix an existing flake in the integration tests. If it
was the case that Alice didn't yet know of all the channels, then the
payment attempt below would fail at times, depending on other timing
factors in the test. We fix this flake by waiting for Alice to learn of
all channels before we proceed to the actual testing logic.
This commit adds a missing return to the resolveContract method, that
will ensure the goroutine exits if the ChannelArbitrator shuts down.
This fixes a potential deadlock during the integration tests.
We also promote some of the logs to Debug from Trace.
In this commit, we fix a long standing bug where at times a co-op
channel closure wouldn't be properly marked as fully closed in the
database. The culprit was a re-occurring code flaw we've seen many times
in the codebase: a closure variable that closes over a loop iterator
variable. Before this instance, I assumed that this could only pop up
when goroutines bind to the loop iterator within a closure. However,
this instance is the exact same issue, but within a regular closure that
has _delayed_ execution. As the closure doesn't execute until long after
the loop has finished executing, it may still be holding onto the _last_
item the loop iterator variable was assigned to.
The fix for this issue is very simple: re-assign the channel point
before creating the closure. Without this fix, we would go to call
db.MarkChanFullyClosed on a channel that may not have yet actually be in
the pending close state, causing all executions to fail.
Fixes#1054.
Fixes#1056.
Fixes#1075.
In this commit, we extend the closeChannelAndAssert testing utility
function to ensure that the channel is no longer marked as "pending
close" in the database. With this change, we hop to catch a recently
reported issue wherein users report that a co-op close channel has been
fully confirmed, yet it still pops up in the `pendingchannels` command.
This commit fixes an issue in funding manager startup,
where a goroutine reads from a range value. The method in
question could cause a channel to be announced at the
wrong time.
This may have been a cause for certain channels having
phantom HTLCs before they had even received the funding
locked message from the remote peer.
This is fixed simply by using the locally scoped
variable passed in as an argument to the goroutine.
