[Freeswitch-users] mod_curl holding call

[Oz Mortimer]

Hi Mailing list,

 

I am having an issue with curl where the app execution doesn't return where
there is an issue resolving domain, even if the caller has hungup. The
billable duration in the CDRS along with the end time stamp both reflect the
script end time rather than call end time.

 

Here is an example to force the issue.

Edit /etc/resolve and set a name server to 9.9.9.9

 

Create a simple lua script

session:answer()

session:execute("curl","http://www.google.com")

 

 

When calling this script via softphone and hanging up during the CURL, I see


2012-01-12 17:29:23.070105 [DEBUG] switch_core_session.c:875 Send signal
sofia/internal/testing at myip [BREAK]

2012-01-12 17:29:23.070105 [DEBUG] switch_core_session.c:875 Send signal
sofia/internal/testing at myip [BREAK]

2012-01-12 17:29:23.070105 [DEBUG] switch_core_session.c:875 Send signal
sofia/internal/testing at myip [BREAK]

2012-01-12 17:29:23.070105 [DEBUG] switch_core_session.c:875 Send signal
sofia/internal/testing at myip [BREAK]

 

And then nothing, until I assume the CURL call ends (including the Callstate
Change ACTIVE -> HANGUP)

If I then look at the cdrs, they also show billable duration inclusive of
the curl timeout even though the call ended some seconds before.

 

I tried setting a hangup hook in the lua but this too doesn't get called
when the call terminated.

 

It seems like the state machine for the call gets stuck until curl
completes.

 

I've just downloaded the git head and the issue is present there too.

 

Obvious question, shouldn't billable duration and end stamp reflect the
actual call? Or is there something I need to do that I've currently missed.

Is this issue specific to curl, or could it happen in other modules?

 

Any pointers?

Many Thanks

Oz.
