| Summary | 0000493: when read old pgpool_status file, wrong variable was referenced by Pgpool-II. | ||||
| Description | Pgpool-II 3.4 or later, a pgpool_status format is changed from binary data to ASCII text. And their version support old format. But read_status_file() function reference wrong variable, when old format file read. 'backend_rec ' variable is read by pgpool_status file. If status is CON_DOWN, it is correct. But if status is CON_CONNECT_WAIT or CON_UP, Pgpool-II read not backend_rec but BACKEND_INFO(i). It isincorrect. read_status_file() #src/main/pgpool_main.c ===================================== if (backend_rec.status[i] == CON_DOWN) { BACKEND_INFO(i).backend_status = CON_DOWN; (void)write_status_file(); ereport(LOG, (errmsg("read_status_file: %d th backend is set to down status", i))); } else if (BACKEND_INFO(i).backend_status == CON_CONNECT_WAIT || BACKEND_INFO(i).backend_status == CON_UP) ===================================== | ||||
