Here we implement the SQLStore methods:
- MarkEdgeZombie
- MarkEdgeLive
- IsZombieEdge
- NumZombies
These will be tested in the next commit as one more method
implementation is required.
Here we add the `ForEachNodeDirectedChannel` and `ForEachNodeCacheable`
SQLStore implementations which then lets us run
`TestGraphTraversalCacheable` and `TestGraphCacheForEachNodeChannel`
against SQL backends.
In this commit, the ForEachSourceNodeChannel implementation of the
SQLStore is added. Since this is the first method of the SQLStore that
fetches channel and policy info, it also adds all the helpers that are
required to do so. These will be re-used in upcoming commits as more
"For"-type methods are added.
With this implementation, we convert the `TestForEachSourceNodeChannel`
such that it is run against SQL backends.
In this commit, the various SQL queries are defined that we will need in
order to implement the SQLStore UpdateEdgePolicy method. Channel
policies can be "replaced" and so we use the upsert pattern for them
with the rule that any new channel policy must have a timestamp greater
than the previous one we persisted.
As is done for the KVStore implementation of the method, we use the
batch scheduler for this method.
In this commit, the `AddChannelEdge` method of the SQLStore is
implemented. Like the KVStore implementation, it makes use of the
available channel `batch.Scheduler` and also updates the reject and
channel caches.
This then lets us convert the following 2 unit tests to run against the
SQL backends:
- TestPartialNode
- TestAddChannelEdgeShellNodes
In this commit, we add the `source_nodes` table. It points to entries in
the `nodes` table. This table will store one entry per protocol version
that we are announcing a node_announcement on.
With this commit, we can run the TestSourceNode unit test against our
SQL backends.
In this commit we add the necessary SQL queries and then implement the
SQLStore's NodeUpdatesInHorizon method. This lets us run the
TestNodeUpdatesInHorizon unit tests against SQL backends.
In this commit, we add the various sqlc queries that we need in order
to implement the following V1Store methods:
- AddLightningNode
- FetchLightningNode
- HasLightningNode
- AddrsForNode
- DeleteLightningNode
- FetchNodeFeatures
These are implemented by SQLStore which then lets us use the SQLStore
backend for the following unit tests:
- TestNodeInsertionAndDeletion
- TestLightningNodePersistence
In this commit, the various SQL schemas required to store graph node
related data is defined. Specifically, the following tables are defined:
- nodes
- node_extra_types
- node_features
- node_addresses
