Hey all,
Have a very peculiar problem. First off -
OS: FreeBSD 4.7
MySQL version: Ver 12.20 Distrib 4.0.13, for unknown-freebsd4.7 (i386)
(I have also compiled 3.23.53)
The problem:
I have written a class that connects to and disconnects from the database.
Everything works fine when I instantiate this class in another class to do
some work, but when that class instantiates yet another class then it seems
as though mysql_real_connect bombs, and I have a core file.
In other works
Works:
class1 {
function foo() {
MYSQL mysql
db.connect (&mysql)
}
};
Does not work:
Class1 {
function foo() {
Class2 cl2;
cl2.fod()
}
}
Class2 {
function fod() {
db.connect()
}
}
I have done all sorts of debugging and inspection, but I am unable to figure
out what is causing this. Please send any ideas.
DB function is here.
(mysql_ptr points to a valid MYSQL object elsewhere)
MYSQL *DB::db_connect (MYSQL* mysql_ptr) {
/*
* connect to the database
*/
char msg_buffer[2000];
Log log;
/*
* initialize the MYSQL pointer
*/
mysql_ptr = mysql_init(mysql_ptr);
if (mysql_ptr == NULL) {
printf ("ERROR: ptr is null!\n");
}
if (!(mysql_real_connect (mysql_ptr, borg.db_host,
borg.db_username,\
borg.db_passwd, borg.db_name, atoi(borg.db_port), NULL, 0))) {
memset (msg_buffer, 0, sizeof(msg_buffer));
sprintf (msg_buffer, "ERROR: Failed to connect to database:
Error: %s.", mysql_error(mysql_ptr));
log.log_entry (0, msg_buffer);
return NULL;
}
return mysql_ptr;
};
