Yes, but that will terminate all current requests handled by that process... try it out and let me know how you get on?

I make some experimets... Test server through falcon serve
and falcon host
... killing self from inside application (from middleware) kills current request immidiate ...
... falcon supervisor restart
stops application I don't understand why ...
But killing through signal HUP whole server works as expected but some requests are broken. Example (2 forks):
- starting rails server (without DB just api) by
RAILS_ENV=production bundle exec falcon host
# falcon.rb
load :rack, :supervisor
rack 'prober' do
scheme 'http'
protocol { Async::HTTP::Protocol::HTTP1 }
count 2
endpoint do
Async::HTTP::Endpoint.for(scheme, '0.0.0.0', port: 3000, protocol: protocol)
end
end
supervisor
- requesting with Yandex Tank 10 rps.
- killing with single
kill -HUP $PID
- ... aplication reloads...
- see broken requests :(

Okay let me take a look.

I believe this is a related issue: #71, and also maybe #22
from falcon.
Sorry, I did not follow up on this, I will take a look today.

I won't get a chance to look at this but I've put it on my planning board.

No worries, it's a nice-to-have, but I appreciate your attention in any case!

Sometimes when I go back I see this in Service::Supervisor
:
# Restart the process group that the supervisor belongs to.
def do_restart(message)
# Tell the parent of this process group to spin up a new process group/container.
# Wait for that to start accepting new connections.
# Stop accepting connections.
# Wait for existing connnections to drain.
# Terminate this process group.
signal = message[:signal] || :INT
Process.kill(signal, Process.ppid)
end
...but there is no such feature in Service::Application
:(
