In this commit, we update an existing migration which at the time of
writing has not been included in a release. We update it so that it
converts the format used for MissionControl result encoding to use pure
TLV instead. The 3 structs that have been updated are: `mcHop`,
`mcRoute` and `paymentResult`.
So that we can use it in TLV encoding.
Also add this to the codec for channeldb migration 32 since we will be
using it there in an upcoming adjustment commit.
Add the TrueBoolean type along with its Record method. Also update the
Millisatoshi type with a Record method. Both of these will be used in an
upcoming commit which adjusts a mission control migration to use pure
TLV types.
fix the signature of the Encode method so that it does in fact implement
the Serializable interface defined in the lnwire21 package. This differs
slightly from the interface defined in the main lnwire package.
In this commit, the mission control store is migrated such that all
existing pairs which are currently stored directly in the top level
results bucket are now instead moved to a "default" namespace bucket.
Note that this migration is not yet invoked in this commit. The
migration will be invoked in the same commit that starts writing and
reading the new format.
Add a new mcRoute type that houses the data about a route that MC
actually uses. Then add a migration (channeldb/migration32) that
migrates the existing store from its current serialisation to the new,
more minimal serialisation.
In preparation for the commit which will add the main logic for
migration 32 (which will migrate the MC store to use a more minimal
encoding), this commit just adds some of the code that the migration
will need to the package.
We add the new custom records encoding/decoding logic to the "frozen"
lnwire21 package. We can do this because nothing uses this logic yet. If
the custom records logic changes, the changes should _not_ be added to
the lnwire21 version.
To prevent the need to copy the entire onion_error.go file for a new
Mission Control migration, this commit just updates the existing
lnwire21/onion_error.go file with the new CodeInvalidBlinding code. The
lnwire21 should not really ever be updated but adding a new code should
be fine as it does not affect old migrations since this is a new code.
In preparation for adding a new message, AnnounceSignatures2 along with
an AnnounceSignatures interface, we rename the existing message to
AnnounceSignatures1.
With this commit we make sure the first hop custom records aren't lost
on restart/resume of a payment, so we persist it as part of the
PaymentCreationInfo struct.
When fetching an AMP invoice we sometimes filter HTLCs to selected set
IDs, however we always kept the full AMP state which is irrelevant as it
contains state for all AMP payments. This was a side effect of
UpdateInvoice needing to serialize the whole invoice when storing after
an update but it is an unwanted "feature" as users will need to filter
to relevant set when listing an AMP payment or subsribing to an update.
This may be useful for custom channel types that base everything off the index (a global value) rather than the output index (can change with each state).
In this commit, we add a TLV blob to the PaymentDescriptor struct. We also now thread through this value from the UpdateAddHTLC message to the PaymentDescriptor mapping, and the other way around.
In this commit, for each channel, we'll now start to store an optional custom blob. This can be used to store extra information for custom channels in an opauqe manner.
In this commit, we consolidate the root bucket TLVs into a new struct.
This makes it easier to see all the new TLV fields at a glance. We also
convert TLV usage to use the new type param based APis.
This commit adds the ability to store closed channels by scid in
the database. This will allow the gossiper to ignore channel
announcements for closed channels without having to do any
expensive validation.
ChanUpdate timestamps are now restircted so that they cannot be
more than two weeks into the future. Moreover channels with both
timestamps in the ReplyChannelRange msg either too far in the past
or too far in the future are not queried.
Moreover fix unitests.
This commit introduces a new API to return information on which party opened
the channel using the new ChannelParty type. It does not change the underlying
structure of how we store this information.
This commit breaks the ChannelConstraints structure into two
sub-structures that reflect the fundamental differences in how
these parameters are used. On its face it may not seem necessary,
however the distinction introduced here is relevant for how we
will be implementing the Dynamic Commitments proposal.
Make various sender side adjustments so that a sender is able to send an
MP payment to a single blinded path without actually including an MPP
record in the payment.
In preparation for adding a clean Graph DB interface, we create a
version of FetchLightningNode that doesnt allow a caller to provide in a
transaction.
In this commit, we completely remove the Router's dependence on a Graph
source that requires a `kvdb.RTx`. In so doing, we are more prepared for
a future where the Graph source is backed by different DB structure such
as pure SQL.
The two areas affected here are: the ChannelRouter's graph access that
it uses for pathfinding. And the SessionSource's graph access that it
uses for payments.
The ChannelRouter gets given a Graph and the SessionSource is given a
GraphSessionFactory which it can use to create a new session. Behind the
scenes, this will acquire a kvdb.RTx that will be used for calls to the
Graph's `ForEachNodeChannel` method.
