Launching a new primary process from a primary

[Antonio Di Bacco]

I know, because I was told by Anatoly Burakov (DPDK developer), that
it is possible to launch a new primary from within a primary using
system() syscall or fork but a few FDs should be closed. Do you know
of a DPDK example that exemplifies such a procedure?

If you don't follow the exact procedure you can generate a deadlock.
This is what I've been told:

There is a way to launch a primary process from another primary in our
test app - if you check the code, it closes a bunch of fd's before
launching the process - that's most likely what you need to do as that
would be what causes the deadlocks (concurrent access from multiple
processes who think they're primaries).

Do you know where can I find the "test app".


Thx.
