Unable to get response in child thread until parent thread remain free.

  Can this be resolved?

Please also note that a service (here B) is free to serialize its requests and to process it one after one, taking the time it requires. So even if there is an issue in afb-daemon, the case is still possible.

Agreeing there is something wrong in afb-daemon, I'd like to find a workaround that could solve your specific issue while waiting for a fix. So let discuss on what you posted...

If I understand correctly, the examples reflect your requirements. Here is what I understand:

1. server-binding is a service that expose some API through binder mechanism, let call it A

2. demo-service-binding is also a service that expose some API through binder mechanism, let call it B

3. the service A depends of the service B. it calls B synchronously

4. starting a thread for each request made to A is required by the logic of the service A

5. the service B called by service A takes some time (sleep 5) what reveals that afb-daemon does not correctly handle multiple request as it should

I tried to use asynchronous calls/subcalls in service A with equal success: it fails because service B does not handle the incoming requests when busy.

Then I modified the service B (demo-service-binding) to either start a thread (solved the issue) or starting jobs (afb_api_queue_job - but fails).

So if you can't change the service B it is not possible to make a workaround and afb-daemon has to be fixed.

it is possible to use asynchronous versions (afb_api_call or afb_req_subcall) but on my test it does not change the issue.

Hello Josh,

Actually this issue is the next part of the . As I mention in https://lf-automotivelinux.atlassian.net/browse/SPEC-4699, I was unable to call server parallelly so I try to add threads in it (as shown in server-binding.c). Here I am calling demo-service from child thread of server. After calling it, I am calling "ping1" verb of server to make main thread of server busy.  (The problem of is still persist here when more than one bindings call server at a time)

So, if you see the log attached below, you will see that although the demo-service have sent the reply to server but child thread of server is not able get that response until the main thread of server ends it's execution.

Question: How  would I get the response in child thread irrespective of main thread is busy or free?

more detail is welcome. does it duplicates ?
