Rack::SocketDuplex is Rack middleware that duplexes HTTP traffic to a unix socket. The primary use case is to subsequently forward this traffic to load test a new production environment (see EXAMPLE section).
- Fairly low overhead (~5ms on small tests with a
em-proxyserver listening on the unix socket). - Ignores SSL traffic.
- Converts Rack env to a raw HTTP request. The conversion tries to be accurate, but there might be discrepancies.
Add Rack::SocketDuplex as middleware in your config.ru or where appropriate:
use Rack::SocketDuplex, "/tmp/rack-socket_duplex"
Use nc or em-proxy to listen to the traffic, and forward it to a new production environment (load testing) or log it to a file.
To add Rack::SocketDuplex to Rails, add the following line to config/application.rb or a specific environment (e.g. config/environments/development.rb):
config.middleware.use "Rack::SocketDuplex", "/tmp/rack-socket_duplex"
See examples/lobster.ru. Run the example app with the following command:
rackup lobster.ru -p 3000
Then open 127.0.0.1:3000 in a browser. To observe what's being written on the socket, run the following command:
nc -klU /tmp/rack-socket_duplex-test
To forward the data efficiently to other servers, use forwarding-proxy from the examples-folder (requries `em-proxy'):
forwarding-proxy.rb /tmp/rack-socket_duplex-test example.com
- Ruby 1.9
- Optional:
em-proxy-gem to useexamples/forwarding-proxy
Add to bundler
gem "rack-socket_duplex", git: "https://github.com/andreas/rack-socket_duplex"
or install as gem
gem install rack-socket_duplex
After checking out the source, run:
rake test
This task will run the tests/specs.
