Hi Tim,

I just committed serial proper forking support into core - it was
migrated from LCR module. I mean proper, since it has q value
support and it can be used by any module without any inter-module
dependencies.
The idea behind was to allow to all module that performs parallel
forking to do also serial forking - exec, enum, registrar, etc.
That's good news! Thank you!
But I have some questions to help me understand the new functions.
Please see below...
There are two new script functions :
*serialize_branches(n)* : it inherits the functionality of
load_contacts() from LCR; gets all parallel branches and convert
them into AVPs for serial forking; numerical parameter 'n' says if
any previous AVP should be removed (if non-0) or not (if 0). Returns
true is no error (even if no serialization happened).
*next_branches()* : it inherits the functionality of
next_contacts() from LCR; get (based on q value) the next contact(s)
to be used in sequential forking. Returns true only if a new
contact was got to be used.
The AVP containing the branches is accessible only via alias - its
ID is not configurable or visible; the alias (automatically exported
by core) is "serial_branch" - it is visible from any module that
uses the avp core aliasing system.
My questions:
Let's say there are 4 contacts registered. Two of the contacts ("A"
and "B") have q value of 1.0. The other two contacts ("C" and "D")
have q value of 0.5.
Using the following routing script, which contacts will be tried in
the main route block, and which will be tried in the failure_route
block?
according to RFC and Q interpretation, you will get in request route
the C and D contacts (as they have the lower q (higher priority) and
their q is equal. In failure route you get A and B (as they have the
same q).

failure_route[1] {
if (next_branches()) {
t_relay();

}
Thank you!
