If the max_htlc field is not found when fetching a ChannelEdgePolicy
from the DB, we treat this as an unknown policy.
This is done to ensure we won't propagate invalid data further. The data
will be overwritten with a valid one when we receive an update for this
channel.
It shouldn't be very common, but old data could be lingering in the DB
added before this field was validated.
Adding this field will allow us to persist an edge's
max HTLC to disk, thus preserving it between restarts.

In this commit:
* we partition lnwire.ChanUpdateFlag into two (ChanUpdateChanFlags and
ChanUpdateMsgFlags), from a uint16 to a pair of uint8's
* we rename the ChannelUpdate.Flags to ChannelFlags and add an
additional MessageFlags field, which will be used to indicate the
presence of the optional field HtlcMaximumMsat within the ChannelUpdate.
* we partition ChannelEdgePolicy.Flags into message and channel flags.
This change corresponds to the partitioning of the ChannelUpdate's Flags
field into MessageFlags and ChannelFlags.

This commit is a preparation for the addition of new invoice
states. A database migration is not needed because we keep
the same field length and values.
In this commit, we address an issue with the FetchWaitingCloseChannels
method where it would not properly return channels that are unconfirmed
and also have an unconfirmed closing transaction because they were
filtered out. We fix this by fetching channels that remain unconfirmed
that are also waiting for a confirmed closing transaction.
This will allow the recently added test TestFetchWaitingCloseChannels to
pass.
In this commit, we add a test case for FetchWaitingCloseChannels to
ensure it behaves as intended. Currently, this test fails due to not
fetching channels which are pending to be closed but are also pending to
be opened. This will be fixed in the following commit and should allow
the test to pass.
Instead return ErrGraphNodeNotFound directly. If the node bucket was
created it would be empty, and the call delChannelByEdge ->
fetchChanEdgePolicies -> fetchChanEdgePolicy ->
deserializeChanEdgePolicy -> fetchLightningNode would return this error
anyway.
This commit adds an optional field LastChanSyncMsg to the
CloseChannelSummary, which will be used to save the ChannelReestablish
message for the channel at the point of channel close.
This commit adds a new file legacy_serialization.go, where a copy of the
current deserializeCloseChannelSummary is made, called
deserializeCloseChannelSummaryV6.
The rationale is to keep old deserialization code around to be used
during migration, as it is hard maintaining compatibility with the old
format while changing the code in use.
In this commit, we add a method to the ChannelGraph struct that
determines whether a node is seen as public based on graph's source
node's point of view.
Previously a call to QueryInvoices with reversed=true and index_offset=1
would make the cursor point to the first available invoice (num 1) that
would be returned as part of the response. This is inconsistent with the
othre indexes, so we instead just return an empty list in this case.
A test case for this situation is also added.
In this commit, we ensure that we only create the sub-bucket for
channels once: at the time of creation. We do this as otherwise it's
possible that a method that mutates a channel's state is called after it
has already been closed on-chain, leading to the channel bucket being
recreated.
Using AbandonChannel, a channel can be abandoned. This means
removing all state without any on-chain or off-chain action.
A close summary is the only thing that is stored in the db after
abandoning.
A specific close type Abandoned is added. Abandoned channels
can be retrieved via the ClosedChannels RPC.
This commit modifies the edge update index
migration to avoid repetitive calls to
Cursor.First(). Instead, we construct a set
of all edge update keys to remove, and then do
a second pass to remove each from the bucket.
Additional log messages are included to notify
users on progress, as some have reported long
migration times.
In this commit, we fix a bug in the latest database migration when
migrating from 0.4 to 0.5. There's an issue in bolt db where if one
deletes a bucket that has a key with a nil value, it thinks that's a sub
bucket and attempts a bucket deletion. This will fail as it's not
actually a sub-bucket. We get around this by using a cursor to manually
delete items in the
bucket.
Fixes#1907.
