Hi!
I started to talk with Vivien offlist but thought this place will be
better, as more heads to think is faster problem resolving :) Basically,
I am running PHP5 module with Apache2 forked (traditional) model and
GDA3 as DB abstraction layer. Problems starts to appear when child
processes die (or killed explicitly). I started to debug issue a bit and
now I found this:
1. I lost connection to MySQL provider when child dies.
2. gda_mysql_provider_close_connection is executed (101% sure), though
no idea where
I used such wrap function:
static void __gda_mysql_close(MYSQL *mysql, const gchar *msg)
{
g_warning("CLOSING MYSQL CONNECTION BECAUSE : %s", msg);
mysql_close(mysql);
}
in gda_mysql_provider_close I replace mysql_close with:
__gda_mysql_close (mysql, "provider_close_conn");
And it's invoked any time, child is killed.
3. 'conn-closed' signal is not emitted
Now I wonder, why connection is closed explicitly when child dies? I
opened it in parent and want to keep it opened as long as parent exists.
I used such callback to conn-closed:
static void _disconnect_cnc_callback(GdaConnection *cnc,
GdaConnectionEvent *event, gpointer ud)
{
g_warning("DISCONNECT CALLBACK!");
return;
}
g_signal_connect(G_OBJECT(connection), "error",
G_CALLBACK(_disconnect_cnc_callback), (gpointer)
ptr);
I am not sure this signal is never emitted. I am sure a callback is
never executed.
I must say I feel blind here, as there's nothing I could take control over.
Last, but not least: GDA3 3.0.4 self compiled with default flags.
