puma-test-socket

tested on Digital Ocean Ubuntu 18.04 droplet

• clone repository
• run ./puma_systemctl_init
• run systemctl start puma.socket puma.service
• run socat TCP-LISTEN:1234,reuseaddr UNIX-CLIENT:/var/run/puma/puma.sock
• open browser and point to http://{IP}:1234/random
• restart puma using systemctl restart puma.service
• run socat again ... rinse&repeat

alternative (without socat, seems a bit more stable):

• curl --unix-socket /var/run/puma/puma.sock http://localhost/random

Logrotate issue

to reproduce:

• follow the above process, reboot to make sure things are clean if necessary
• check the log file in /var/log/puma.log, it should show some entries
• tail this file using tail -f /var/log/puma.log &
• run logrotate -f /etc/logrotate.d/puma - this would rotate the log and start a phased-restart
• from that point however, /var/log/puma.log is empty, and data keeps being appended to /var/log/puma.log.1
