Unicorn::Timeout

Middleware for timing out current unicorn worker if request takes to long time.

If a request times out, a handler block will be called and the current worker process will be killed (using SIGTERM).

The gem is tested using Ruby 1.9.3p194.

Add this line to your application's Gemfile:

gem 'unicorn-timeout'

And then execute:

$ bundle

Or install it yourself as:

$ gem install unicorn-timeout

In config/application.rb:

config.middleware.use Unicorn::Timeout

In config/initializer/unicorn-timeout.rb (optional):

# Timeout in seconds
Unicorn::Timeout.timeout = 15 # default

# Block that will run (within Thread.exclusive, on monitor thread) just before sending signal to process
Unicorn::Timeout.handler = lambda { |backtrace| STDERR.puts("Unicorn::Timeout is killing worker ##{Process.pid} with backtrace:\n#{backtrace.inspect}") } # default

# Signal that will be sent to current process if timeout is reached
Unicorn::Timeout.signal  = "TERM" # default

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

This work was inspired and influenced by rack-timeout.
