Hello,<br>
<br>
I pushed a fix that should release the json object:<br>
<br>
-
<a class="moz-txt-link-freetext" href="http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=def8d2600422a442b971c204df98594b0dfdaacd">http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=def8d2600422a442b971c204df98594b0dfdaacd</a><br>
<br>
<pre wrap="">dst_pv->setf() should copy (clone) of the string value and then the object can be unreferenced.</pre>
<br>
If works ok, then I will backport -- I didn't have any server with
json library at hand to give it a minimum test.<br>
<br>
Cheers,<br>
Daniel<br>

<div>Hi:</div>
<div>I am trying to use json module in script
with json_get_field exported api, I found in it's
implementation, the api will call struct json_object *j =
json_tokener_parse(json_s.s); but didn't call
json_object_put for this j object, then the object will
leak. So my question is how to release the new j object?
We can't release in json_get_field(), that will cause the
returned string become to rubbish, thanks!</div>
<div>Below is the api's code in module\json\json_funcs.c:</div>
<div>
<div>int json_get_field(struct sip_msg* msg, char* json,
char* field, char* dst)</div>
