Function mas_pre_migration_checks

Source 
pub async fn mas_pre_migration_checks(
    mas_connection: &mut LockedMasDatabase,
) -> Result<(), Error>
Expand description

Check that a MAS database is ready for being migrated to.

Concretely, this checks that the database is empty.

If syn2mas is already in progress on this database, the checks are skipped.

§Errors

Errors are returned under the following circumstances:

  • If any database access error occurs.
  • If any MAS tables involved in the migration are not empty.
  • If we can’t check whether syn2mas is already in progress on this database or not.
