Hi Liviu,
I have tested the patch. Now I see the delay is 2 secs. i.e after 2
secs it sends the HTTP request out.
I suspect this 2000 ms delay is due to the below field:
long connection_timeout = 20;
Can we reduce this field to 5 or 10, so that it waits only half a
second or second to send the request out.
Let me know your thoughts on this.
Am seeing the below message in logs. Is everything working as you
expected?
rest_client:start_async_http_req: libcurl TCP connect: we should wait
up to 1ms (timeout=20000ms)!
Regards,
Agalya

Hi, Agalya!
Regarding the 10s delay problem, a fix was pushed to the development
branch [1]. If you are running on 2.1.4 git branch, could you please
pull the latest changes (git pull --rebase), and test it out? You can
import it with:
git cherry-pick -x 66c337cc

Hi team,
Any clue on this below topic would be a great. Am stuck with this
10 sec delay and couldn’t move further.
If I could be able to find the root cause and resolve this , then
only I can implement REST API calls as async.
Because this 10 sec delay is a huge time. Please help me on this.

Hi Liviu,
A clue for this 10 sec delay consumed by opensips before sending
the HTTP request, will be grateful for me. As far as I debugged
this delay is caused by curl library. But wondering what could be
the cause for this constant 10.25 sec delay.?
Please help me out in this.

Agalya

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

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 timeJ. 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.
