Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Crash with db_postgres and presence Initial Comment: (submitted by [email protected]) The problem is as follows - a query is executed, but for some reason the results from the previous one are read back from the DB driver, which in turn makes opensips to crash as the number of columns is lower and it tries to dereference stuff that doesn't exist. Appended are the log and the backtrace: Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_submit_query: 0x8197240 PQsendQuery(select status,reason from watchers where presentity_uri='sip:bbb%[email protected]' AND watcher_username='aaa%40ccc.com' AND watcher_domain='10.2.30.5' AND event='presence') Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:core:db_new_result: allocate 28 bytes for result set at 0x81a0948 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_store_result: 0x8197240 PQresultStatus(PGRES_TUPLES_OK) PQgetResult(0x94c0300) Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_get_columns: 1 columns returned from the query Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:core:db_allocate_columns: allocate 16 bytes for result columns at 0x819ecd0 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_get_columns: RES_NAMES(0x819ecd8)[0]=[username] Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_get_columns: use DB_STRING result type Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_convert_rows: allocate for 1 columns 4 bytes in row buffer at 0x819d5b8 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:core:db_allocate_rows: allocate 28 bytes for result rows and values at 0x819f870 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_convert_rows: PQgetvalue(0x8197240,0,0)=[[email protected]] Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_convert_rows: allocated 11 bytes for row_buf[0] at 0x819d5c8 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_convert_rows: [0][0] column[username]=[[email protected]] Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_str2val: converting STRING [[email protected]] Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:db_postgres_convert_rows: freeing row buffer at 0x819d5b8 Feb 12 13:42:59 f-ast2 opensips[29504]: DBG:db_postgres:free_query: PQclear(0x94c0300) result set Feb 12 13:42:59 f-ast2 opensips[29507]: DBG:db_postgres:db_postgres_store_result: 0x8197100 PQresultStatus(PGRES_TUPLES_OK) PQgetResult(0x94bb108) Feb 12 13:42:59 f-ast2 kernel: [842163.893756] opensips[29504]: segfault at 1 ip b77b98c6 sp bff1ab30 error 4 in presence.so[b7790000+31000] Core was generated by `opensips'.
