channeldb: ensure restored channels can't be mutated 2019-01-28 20:24:48 -08:00

channeldb: add new RestoreChannelShells method
In this commit, we add a new type (ChannelShell) along with a new
method, RestoreChannelShells which allows a caller to insert a series of
channel shells into the database. These channel shells will allow a
restored node to initiate the DLP protocol and recover their set of
existing channels.

When we insert a channel shell, we re-create the original link node, and
also add the outgoing edge to the channel graph. This way we can be sure
that upon start up, we attempt to connect to the remote peers, and that
the normal graph query commands will operate as expected.

channeldb: when fetching/inserting commits check for ChanStatusRestored
If the ChanStatusRestored flag is set, then we don't need to write or
read the set of commits for a channel as they won't exist. This will be
the case when we restore a channel from an SCB.

channeldb: refactor syncPending to expose new syncNewChannel function
The new syncNewChannel function will allow callers to insert a new
channel given the OpenChannel struct, and set of addresses for the
channel peer. This new method will also create a new LinkNode for the
peer if one doesn't already exist.

channeldb: add HasChanStatus and ApplyChanState methods to OpenChannel
These methods allow callers to properly query if a channel is in a
particular flag, and also modify the channel status in a thread safe
manner.

channeldb: modify the String() method of ChannelStatus reflect all flags
In this commit, we modify the String() method of the ChannelStatus type
to reflect the fact that it's a flag set. With these new changes, we'll
now print the variable name of each assigned bit with a bar delimiting
them all.

channeldb: add prefix naming to ChannelStatus enum variables
In this commit, we add a prefix naming scheme to the ChannelStatus enum
variables. We do this as it enables outside callers to more easily
identify each individual enum variable as a part of the greater
enum-like type.

channeldb/channel: ignore ChannelEdgePolicy with missing max_htlc
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.

channeldb/graph: add max HTLC to ChannelEdgePolicy
Adding this field will allow us to persist an edge's

multi: partition lnwire.ChanUpdateFlag into ChannelFlags and MessageFlags
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.

70d3fc640a channeldb/db: prevent filtering channels with unconfirmed close txs
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.

409efd1361 channeldb/channel_test: add TestFetchWaitingCloseChannels
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.

channeldb/legacy_serialization: add deserializeCloseChannelSummaryV6
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.
