Hi Liviu,
Here is the dump from the time when the socket is opened and when the request
sent out.
Highlighted in RED color. Any clue for this 10 sec delay?

Subject: RE: FW: [OpenSIPS-Users] Asynchronous operation for REST queries
Hi Liviu,
As I already emailed you, to contribute the source code there is some approval
process in our organization.
If that goes though I can contribute the REST PUT code.
But I have a question in async operation in opensips.
When a async mode REST API is called either POST/PUT, I see that opensips waits
for 10 sec of time and then only it sends out the HTTP request out to the
network.
Why there is a huge wait time of 10sec?
When I tried to debug, I found it is looping inside the below for loop for long
time in rest_methods.c file, (but all that looping are taking same seconds,
later 10 sec am getting HTTP response)
for (i = 0; i < busy_wait; i += check_time) {.....}
Wondering and interested to know about this delay time.
Please bear some of your time:). Thanks in advance.
Regards,
Agalya

Hi Agalya,
I am very busy these days and cannot afford to troubleshoot random problems
with libcurl usage. Do you intend to open source the PUT function by making a
Pull Request, after we fix it? If yes, it will definitely go up in my priority
queue.

Subject: RE: [OpenSIPS-Users] Asynchronous operation for REST queries
Hi Bogdan/Liviu,
I have downloaded 2.1.4 version if opensips and trying to use rest_put call in
async mode.
I have added the necessary code for rest_put () similar to rest_post() in
rest_methods.c, rest_methods.h and rest_client.c
If I just call, rest_put from config file, without async it works fine. I could
see rest_put() is called and do the necessary steps.
And am trying to call async from config file as,
async(rest_put("http://***url*** <http://***url***%20> ", "$fU,$tU,$ci ",
"application/json", "$var(body)", "$var(ct)", "$var(rcode)"),resume_put);
Further debugging I got some info that I can share with you so that you can
help me out easily.
Instead of calling rest_put asynchronously I have tried to call rest_post async
. I could able to see that HTTP request went out(from Wireshark traces) and I
got 4xx response for the same.
With my code changes in place and when I call rest_put, am not seeing HTTP
request sent out.
Assuming rest_put only is not working, there should be some libcurl stuffs not
handled properly in 'start_async_http_req' for 'REST_CLIENT_PUT' case.
Am attaching the files that contains code changes for rest_put only. I have
removed other code in order to reduce the file size. Can you please take a look
guide me here?.
Please let me know if you need more information on this.
Regards,
Agalya

Hi Agalya,
1.11 has no async support at core level. If you need that, you will have to use
2.1+
Async rest_put() is currently not implemented, but its logic would be fairly
similar to the GET and POST counterparts.

Hi team,
We are using opensips1.11.3 version for our project.
I have a question here. Right now we are using a REST API call from config file

Is it possible to change in asynchronous mode in 1.11 version?
If not, is there a way to achieve asynchronous REST calls for the version of
opensips what we are using?
Also I see from documentation,
The following functions may also be called asynchronously:
*
avp_db_query<http://www.opensips.org/html/docs/modules/2.1.x/avpops.html#id294986>
*
rest_get<http://www.opensips.org/html/docs/modules/2.1.x/rest_client.html#id293741>
*
rest_post<http://www.opensips.org/html/docs/modules/2.1.x/rest_client.html#id293886>
* exec<http://www.opensips.org/html/docs/modules/2.1.x/exec#id294052>
Can rest_put can also be called asynchronously if we use 2.1 version ?
Please clarify.
Regards,
Agalya
