[libdbi-users] Memory leak when using dbi_initialize in loop
Hi,
Using libdbi on Fedora 14:
libdbi-dbd-sqlite-0.8.3-6.fc14.i686
libdbi-devel-0.8.3-4.fc14.i686
libdbi-0.8.3-4.fc14.i686
libdbi-drivers-0.8.3-6.fc14.i686
libdbi-dbd-mysql-0.8.3-6.fc14.i686
The following code continues to allocate memory, but, doesn't
deallocate it. Can you please let me know what is wrong?
=== CODE ===
#include stdio.h
#include dbi/dbi.h
int main() {
dbi_conn conn;
while (1) {
dbi_initialize(NULL);
conn = dbi_conn_new(mysql);
dbi_conn_set_option(conn, host, localhost);
dbi_conn_set_option(conn, username, foo);
dbi_conn_set_option(conn, password, bar);
dbi_conn_set_option(conn, dbname, test);
dbi_conn_set_option(conn, encoding, UTF-8);
if (dbi_conn_connect(conn) 0) {
printf(Could not connect. Please check the option settings\n);
}
else {
/* Do something, and delay */
dbi_conn_close(conn);
}
dbi_shutdown();
}
return 0;
}
=== END ===
I am trying to do a task after the database connect, give a delay and
loop around, but the above flow is leaking memory. Appreciate any
inputs in this regard!

Hi Markus, I came across this memory leak post: http://comments.gmane.org/gmane.comp.db.libdbi.devel/309 Is this fixed in the sources and am I using old version of the software? libdbi-devel-0.8.3-4.fc14.i686 libdbi-0.8.3-4.fc14.i686 libdbi-drivers-0.8.3-6.fc14.i686 libdbi-dbd-mysql-0.8.3-6.fc14.i686 SK -- Shakthi Kannan http://www.shakthimaan.com -- BlackBerryreg; DevCon Americas, Oct. 18-20, San Francisco, CA The must-attend event for mobile developers.
