One more thing I've figured out:
In dispatcher module guide there is a way to mark dst as Active,
though in src w_ds_mark_dst1 has no such option.
On the other hand, w_ds_mark_dst1 has an option to mark dst as "admin
disabled" that is not documented in the guide.
Could you clarify what is the expected behavior so I could send a fix
for that.
The purpose of that function is to be able to set a destination in one
of supported states:
- completely disabled (admin disabled) -- I guess is 'd' -- not used and
no chance to activate it automatically upon a successful probing request
(actually no probing will be done)
- inactive state - is not used currently, but if in probing mode, it can
be activated automatically if a probe request is answered
- active state - used currently
The probing mode that comes as a flag, is related to whether to send
periodically (probe) requests to check if targets are online.
Trying wasn't coded by me (iirc :-) ), but I think the purpose was to
still keep the target in active mode until a certain number of failures
occur and then make it inactive (or disabled).
If you find discrepancies in the code, let us know -- of course, patches
are more than welcome!
Cheers,
Daniel

Hi Daniel,
1. Yep, had the same concern, but somehow missed the app_lua.
Fixed as you've described.
2. Done.
New patch attached.

Hello,
thanks for sending the patch! Two remarks for now:
1) you changed the inter-module API prototype for
ds_select_dst_f, respectively:
typedef int (*ds_select_dst_f)(struct sip_msg *msg, int set,
- int alg, int mode);
+ int alg, unsigned int limit, int mode);
I think the reason for that function is an export to app_lua
(and maybe other embedded languages). With this change, things
get broken there. I would do:
- rename the function ds_select_dst() to ds_select_dst_limit()
- add ds_select_dst() as a wrapper function calling the new
ds_select_dst_limit()
The API stay unchanged, and eventually one can add a new
member for ds_select_dst_limit() when needed
Otherwise, the change of ds_select_dst() prototype should
involve reviewing other modules and seeing if people are happy
with this change, because it breaks existing embedded scripts.
2) You need to document the new functions exported to kamailio
config, in modules/dispatcher/doc/dispatcher_admin.xml
Once the patch is overall ok, I can commit it to the repository.
Cheers,
Daniel

Hi list,
I'd like to propose a patch that allows user to limit the
number of items that appears in dst_avp after ds_select_dst
or ds_select_domain call.
There are some use cases when one could have couple of dst
sets and would like to failover from the first to another
without checking all items but have just 3 or 4 of them dead
in a row.
What do you think about that?
