Binder on client side randomly fails subscription

Description

Hi,

 

I find the afb-binder on client side ignores subscription randomly, so could you see the code?

I input the error log in afb-proto-ws.c, then found the place of error.

 

 

 

 

Then,  "static struct client_call *client_call_search_locked" function(line 453) fails to find  struct client_call in mutex_lock

 

 

Note: I would like to get strace log but I couldn't because I couldn't reproduce when I execute with strace( write in service file like below). And I tried execute gdb with afb-daemon but GUI application couldn't find API , so couldn't try to call subscribe.... so sorry , I have only the place of error currently.

 

 

When I changed the code of server side from using afb_event_push to using afb_event_broadcast, then success to notify client of events.

 

Environment

GG 7.0.2

Thank you for the feedback and the closing.

And yes, just replacing the binder is fine.

I tested on guppy, then it seems to be solved. ( I don't change image. Just I replaced afb-daemon and libafbwsc.so.1.1 only, but I think it's enough)

Pb seems to be solved with the proposed serie of patches (tested on master only) .

Submit them - we can have ci builds running in parallel.

Plan is to get things merged and tagged before leaving for ALS.
