Large Scale Identification of Race Conditions (In OpenStack CI) - Joe Gordon, HP

Sign up or log in to save this to your schedule and see who's attending!

Does your project have a CI system that suffers from an ever-growing set of race conditions? We have the tool for you: it has enabled increased velocity despite project growth.
Richard Stallman once said, “it turned out that debugging these asynchronous multithreaded programs was really hard.” With 30+ asynchronous services developed by over 1000 people the OpenStack project is an object lesson of this problem. One of the consequences is race conditions often leak into code with no obvious defect. To address this problem we have developed an ElasticSearch based toolchain called “elastic-recheck.” This helps us track race conditions so developers can fix them and identify when CI failures are related to the failed patch or are due to a known pre-existing race condition. elastic-recheck has saved countless hours while allowing us to better manage our race conditions.
