/* * Statistics logging configuration requires either a wait time or an * on-close setting. */ if (*runp == 0 && !FLD_ISSET(conn->stat_flags, WT_CONN_STAT_ON_CLOSE)) return (0); ret = (__wt_config_gets(session, cfg, "statistics_log.sources", &cval)); ret = (__wt_config_subinit(session, &objectconf, &cval)); for (cnt = 0; (ret = __wt_config_next(&objectconf, &k, &v)) == 0; ++cnt) ; WT_RET_NOTFOUND_OK(ret);
