* another way to check if account has storage * cleanup * v0 of walk by db version * save progress, to switch to another task. Put tombstone is still not correct. * place tombstone only if exists something to hide * db-based implementation * db-based implementation * db-based implementation * fix prop check * improve prop check logic * Need custom logic to skip subtree for account and storage buckets because storage bucket has incarnation in key * rebase to master * remove all tombstones when account deleted * remove all tombstones when account deleted * added db integrity check * don't rely on account.Root because it valid only about last incarnation * remove all tombstones when account deleted * dial with incarnation in MultiWalk2 * dial with incarnation in MultiWalk2 * when fixedbytes=40 resolver did compare cacheKey with storageKey without removing incarnation * rebase to master * rebase to master Co-authored-by: alex.sharov <alex.sharov@lazada.com>
