Running

Checking a website for races

• Obtain a ER_actionlog file by exploring a website with an instrumented browser (see https://github.com/eth-srl/webkit)
  • You can use the binary distribution from http://eventracer.org/ and use only the browser from it.
• Run the race analyzer
  • bin/eventracer/webapp/raceanalyzer [the ER_actionlog file]
  • The above command starts a web server on port 8000 (can be changed with a --port parameter to the above command)
  • Open http://localhost:8000/ to see the races

Read our paper "Effective Race Detection for Event-Driven Programs" to understand the meaning of uncovered races and the race filters. Enjoy the tool and develop web applications that provide a great user experience.
