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).
Compatibility
The gem is tested using Ruby 1.9.3p194.
Installation
Add this line to your application's Gemfile:
gem 'unicorn-timeout'
And then execute:
$ bundle
Or install it yourself as:
$ gem install unicorn-timeout
Setup/Usage (Rails 3)
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
