I've totally lost. before_fork is executed in parallel by the number of
workers set in the "worker_processes". I've tested the following:
before_fork do |server, worker|
`echo "before_fork $$" >> /tmp/kk`
after_fork do |server, worker|
`echo "after_fork $$" >> /tmp/kk`
And this is the file output:
Could I know what is happening please? This really breaks the concept I had.
In fact I use before_fork to check database connections and so, but I've
realized that such check if done N (number of workers).
Thanks for any help.
