global variable in after_fork

global variable in after_fork

[Joe Williams]

I am attempting to do something like the following:

after_fork do |server, worker|
  $unicorn_uptime = Time.now.to_i.to_s
  $unicorn_uptime.freeze
<snip>

Unfortunately the variable comes up nil when later accessed. Anyone have
thoughts on what I am missing?

Thanks!
-Joe

I tried your after_fork hook with the following config.ru
and it prints out $unicorn_uptime fine:

-------------------- config.ru --------------------------
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
run lambda { |env| [ 200, {}, [ "#$unicorn_uptime\n"] ] }
---------------------------------------------------------

Perhaps you have something else in your app clobbering globals?

Also, please don't send any HTML parts in mail, it is spammy and wastes
