Hi List,
I want to implement serial forking with avpops module and I have this
problem. The set of destinations for each user is stored in a database and I
use apv_db_load to load it. However, I couldn't find a way to sort them in
the right order. For example, I cant tell SER to try destination A before B,
then C because there is no way to specify this in the database. Another
feature I want to implement is to allow a client to specify a timeout for a
destination. Eg. Try A for x seconds, then try B for y seconds, then try C.
I wonder if there are ways to implement the services above using actual
ser modules or it's not yet possible.
Best regards,
Minh

if you use location table to store the destinations, then you can use
lcr module to implement serial forking according to q value.
Another
feature I want to implement is to allow a client to specify a timeout for a
destination. Eg. Try A for x seconds, then try B for y seconds, then
try C.
lcr module has a timer variable that is used to timeout all but the
last destination.

Hi Minh,
After loading the AVPs via apv_db_load() function you will have in
memory the AVP list exactly in the revert order than in database. Ex: if
you had for avp "test" values A, B, C and D, after loading you will have
the order D, C, B and A.
Regarding the timeout value, to set different values for each step, just
do :
avp_write("i:10", "fr_inv_timer_avp");
before each call of t_relay() - instead of 10, put whatever value you want;
If you are using the development branch, you can set the value for
timeout directly from another AVP (perhaps loaded also from DB):
avp_copy("my_avp", "fr_inv_timer_avp");
Best regards,
Marian

New subject: [Serusers] how to sort data retrieved from avp_db_load in avpopsmodule
Hi Minh,
After loading the AVPs via apv_db_load() function you will have in
memory the AVP list exactly in the revert order than in database. Ex: if
you had for avp "test" values A, B, C and D, after loading you will have
the order D, C, B and A.
Can anyone think of a way to set the order in the database? I think that it
is probably impractical, if not impossible.
Is this reverse order by design or by implementation? My ser logic heavily
relies on the behavior. I wonder if any future upgrade might break it if it
is just how the code is implemented.

If you want to have ordering for AVP of same name/ID at load_db time you
need to relay on some information/order already existing in the DB. At
the moment, the only available criteria is the DB order itself.

The revert order is a effect of how the AVP core is implemented - the
AVPs are kept in singled-linked list and any new APV is added at the
beginning of the list.

you would need some field(s) in the database for ordering and then use
ORDER BY in SELECT.

there are modules that would break if reverse order is changed to
something else.
