Re: [vpp-dev] vppcom_session_connect blocking or non blocking

[Florin Coras]

Hi Max, 

We don’t currently propagate and therefore map vpp errors onto vcl connection 
errors, so you can’t retrieve the error number through vcl.

 Hello,
 
 Can vppcom_session_connect() function run in non-blocking mode? I see that 
 there is a wait for the connection result in the 
 vppcom_wait_for_session_state_change function.  Is it possible to get the 
 result of the connection using vppcom_epoll_wait?
 
 Thanks.

Hi Florin,
 
These events are enough. How can I get the error number? I see that 
VPPCOM_ATTR_GET_ERROR is not working yet.
 
Thank you.

Re: [vpp-dev] vppcom_session_connect blocking or non blocking

[Florin Coras]

Hi Max, 

I had this patch [1] that indirectly fixes the issue lying around. So, is an 
EPOLLOUT | EPOLLHUP event enough to signal a failed async connect for you?

Thanks,
Florin

Re: [vpp-dev] vppcom_session_connect blocking or non blocking

[Max A. via Lists.Fd.Io]

Hi Florin,
 
vppcom_session_connect in non-blocking mode works well only if the connection 
can be successfully established. If the connection cannot be established, then 
no event is raised about this. How can this be fixed?
 
Thanks.

Re: [vpp-dev] vppcom_session_connect blocking or non blocking

Hi Max,

Not at this time. It should be possible with a few changes for nonblocking 
sessions. I’ll add it to my list, in case nobody else beats me to it.

[vpp-dev] vppcom_session_connect blocking or non blocking

[Max A. via Lists.Fd.Io]

Hello,

Can vppcom_session_connect() function run in non-blocking mode? I see that 
there is a wait for the connection result in the 
vppcom_wait_for_session_state_change function. Is it possible to get the result 
of the connection using vppcom_epoll_wait?

Thanks.
