* sverker/heart-nice-exit/OTP-15599:
erts: Avoid heart killing a nicely exiting emulator
|
|
|
|
The macro command was added quite recently and far from
all of our testmachines have this command
|
|
The idea here is that the timeout of 0 will work like a yield
so that that we don't starve other ports/processes, but it
is faster than the select trigger. We don't deselect on the socket
because it does not matter if it is triggered laster or not
as we'll just get an EAGAIN.
Doing this also circumvents the fact that no select is done on
active true style sockets until all I/O has been handled. So in
a system with a lot of active true style I/O this will could be
very benificial.

This is most likely a copy-paste bug that has lived in the code
unnoticed for 5+ years...
|
|
We only want to autoupdate update the buffer if recbuf
is set if the buffer has not been set before.

Symptom:
Heart kills exiting emulator before is has flushed all ports
and with HEART_KILL_SIGNAL=SIGABRT it may also produce
unnecessary core dumps from doing init:reboot() for example.
Problem:
Heart port is closed together with all the others in handle_reap_ports()
which is detected by heart OS process.
Solution 1:
Leave the heart port alone in handle_reap_ports() and let it be closed
by OS when emulator exists. It doesn't need to be flushed anyway.
Solution 2:
When heart OS process gets EOF on connection let it wait max 5 seconds
for emulator process to self terminate before trying to kill it.
