This commit starts reusing test cases which are not dependant on
the kv db backend. So they can be later used with the native db
implementation as well.
This commit adds an itest that verify the behaviour of correctly
reusing persisted node ann configs across restarts. It also ensures
that the node ann configs are applied using the correct hierarchy.
This commit ensures that we start with the alias, node color,
addresses, and features as advertised in the node's previous
runtime. This approach maintains consistency in the node's
advertised information across restarts.
This commit moves most of the code into its own package. It is
the smallest code move possible without moving import cycles and
keeping the changes to the code base as small as possible during
refactor.
We put this new schema update into the main line and change the
versions of the schema updates which are currently only available
in dev builds. The schemas need to be chronological therefore we
also need to rename the file numbers.
This method is not only used by the payment logic so we need to
move it to a generalized place because in the following commits
we move payment related code into its own package.
Finally, we update the migrateZombieIndex function to use batch
validation just like was done in the previous commits. Here, we
additionally make sure to validate the entire zombie index entry and not
just the SCID.
As was done in the previous commits for nodes & channels, we update the
migrateClosedSCIDIndex function here so that it validates migrated
entries in batches rather than one-by-one.
As was done in the previous commits for nodes & channels, we update the
migratePruneLog function here so that it validates migrated entries in
batches rather than one-by-one.
Restructue the `migrateChannelsAndPolicies` function so that it does the
validation of migrated channels and policies in batches. So instead of
fetching channel and its policies individually after migrating it, we
wait for a minimum batch size to be reached and then validate a batch of
them together. This lets us make way fewer DB round trips.
Restructue the `migrateNodes` function so that it does the validation of
migrated nodes in batches. So instead of fetching each node individually
after migrating it, we wait for a minimum batch size to be reached and
then validate a batch of nodes together. This lets us make way fewer DB
round trips.
We do this so that this lookup is only done in the situation it is
actually needed. During a migration, we dont need to special case this
AlreadyExists error since we will terminate the transaction either way.
So there is no need for the extra lookup during the migration.
A timing analysis showed that this query was significantly impacting the
performance of the migration when run with a postgres backend.
This commit adds a BenchmarkFindOptimalSQLQueryConfig test in the
graph/db package which runs ForEachNode and ForEachChannel queries
against a local backend using various different values for the sql
QueryConfig struct. This is done to determine good default values to
use for the config options for sqlite vs postgres.
Now that the SQL query config values are configurable, we add some
validation to make sure that the user doesnt set a max batch size that
is larger than the limits for sqlite/postgres that have been determined
by the TestSQLSliceQueries test.
Here, we make the sql query option params (batch size and pagination
size) configurable. The defaults for SQLite vs Postgres are still the
same but will be changed in an upcoming commit.
