Summary: complete dispatcher failover
Initial Comment:
Version 1.3
I have modified dispatch.c to probe all current gateways in the dispatcher
list. If a probe fails or times out the gateway is put into "probing" mode
where it is no longer active and won't be chosen from the destination list. On
the other hand if a probe succeeds the gateway is put into "active" mode and
will be available in the list.
By setting the ds_ping_interval you are essentially forcing openSER to probe
each gateway at that interval. The code modification was minimal and goes a
long way past probing only the failed gateways.
ds_is_from_list() has been modified to return true only if that gateway is in
the list AND not "probing". This function was modified to allow me to use
database driven intelligent load balancing for call distribution and to double
check the database chosen destination against the internal dispatcher list to
be certain the gateway is available. So:
avp_pushto("$duri", "$var(dStr)");
if (ds_is_from_list())
... the gatey is up
else
... the gateway is down check DB again
ds_options_callback() has been modified to set a gateway to probing in case a
probe fails or times out.
ds_check_timer() has been modified to probe all gateways, not just the ones in
"probing" state.
If implemented in a future release I would suggest adding some options that
allow the user to probe only failed gateways, as in the current release, or all
gateways as in my modification.
