Here, we add a new `buildNodeWithBatchData` helper method that can be
used to construct a `models.LightningNode` object using pre-fetched
batch data. The existing `buildNode` method is then adjusted to use this
new helper.
In this commit, we add the queries that will be needed to batch-fetch
the data of a set of nodes. The logic for using these new queries is
also added but not used yet.
In this commit, we remove the LEFT JOIN query that was used for fetching
a nodes addresses. The reason it was used before was to ensure that we'd
get an empty address list if the node did exist but had no addresses.
This was for the purposes of the `AddrsForNode` method since it needs to
return false/true to indicate if the given node exists.
This commit adds a helper test that is similar to TestPopulateDBs except
for the fact that it uses the MigrateGraphToSQL function directly to
migrate a local kvdb-sql graph to a native SQL one.
This is a prep commit that just adds all the boilerplate connection
logic for connecting to various graph DBs. These will be used in
upcoming commits which will add tests and benchmarks.
Use the new `SLICES` directive to add a DeleteChannels query which takes
a set of DB channel IDs. Then replace all our calls to DeleteChannel
with a paginated call to DeleteChannels.
This commit adds a new GetChannelsByOutpoints query which takes a slice
of outpoint strings. This lets us then update PruneGraph to use
paginated calls to GetChannelsByOutpoints instead of making one DB call
per outpoint.
In preparation for tests where we will want to spin up SQL DBs many
times, we do some refactoring so that it is easy to re-use postgres
fixtures since those are expensive to spin up.
This commit passes no-op reset callbacks to various places where they
are needed in the KVStore. Upcoming commits will replace the no-ops by
adding reset params to the methods that require it.
This commit expands `MigrateGraphToSQL` to include migration of the
zombie index.
NOTE: we take this opportunity to clean up the zombie index a bit by
first checking for each channel in the zombie index if it has been
marked as closed in the closed-scid index. If it has, then there is no
need to include it in the zombie index. A special case test for this
is added too.
In this commit, the `MigrateGraphToSQL` function is expanded to migrate
the channel and channe policy data. Both of these have the special case
where the kvdb store records may contain invalid TLV. If we encounter a
channel with invalid TLV, we skip it and its policies. If we encounter a
policy with invalid TLV, we skip it.
The `TestMigrateGraphToSQL` and `TestMigrationWithChannelDB` tests are
updated accordingly.
