ID: 9681 User Update by: olivier@lx.student.wau.nl Status: Open Bug Type: *Session related Description: can't use interbase functions in user defined sessions On a different machine, the same code generates as segfault. PHP is a freshly compiled ( with --enable-debug) 4.0.4pl1, Apache is 1.3.9 from Debian Potato.

Logging is done to a file that is truncated by the open function, and then a line appended by each other session function. When I start with the example session handler from the manual, everything works ok. Then I start adding interbase functions. Session reading works. BUT, when I add interbase functions to writing, that function is not called anymore (it doesn't write it's entry in the logfile anymore). The same for adding ibase_commit() or ibase_close() to the close function, it doesn't write it's log entry anymore. I tested the queries, and they _do_ work. A working write function: function ibs_write($key, $val) { global $ibs_local_key, $ibs_db_id; $fd = fopen('/home/pkedu/olivier/nwuser/log.out', 'a'); $dbkey = addslashes($key.$ibs_local_key); $val = addslashes($val); $now = time(); $query = "update user_info set session_data='$val' where user_id = (select user_id from user_session where session_key='$dbkey')"; // $ret = ibase_query($ibs_db_id, $query); fputs($fd, $query."n"); fclose($fd); } This is the same function where it doesn't work anymore, only thje comment is removed, and now the query is not written to the logfile anymore: function ibs_write($key, $val) { global $ibs_local_key, $ibs_db_id; $fd = fopen('/home/pkedu/olivier/nwuser/log.out', 'a'); $dbkey = addslashes($key.$ibs_local_key); $val = addslashes($val); $now = time(); $query = "update user_info set session_data='$val' where user_id = (select user_id from user_session where session_key='$dbkey')"; $ret = ibase_query($ibs_db_id, $query); fputs($fd, $query."n"); fclose($fd); } The system does not have any other problems with interbase or sessions, I tried normal and persistant database connections, PHP does not crash (no reports in the apache error_log). Apache is Apache/1.3.9 from Debian Potato. Please contact me for any missing information. --------------------------------------------------------------------------- Full Bug description available at: http://bugs.php.net/?id=9681
