From Webrev to Betterrev Facilitating Contributions to OpenJDK

Daniel Bryant @taidevcouk Mani Sarkar @theNeomatrix369 London Java Community @ljcjug Adopt OpenJDK @adoptopenjdk

Difficulties for the Public Contributors

“Getting started can be daunting…”

“This doesn’t quite feel like ‘social coding’”

Thorough testing is challenging...

Visibility of contributions

Difficulties for Oracle & Committers

Quality of contributions can be problematic

Discussions on incorrect mailing lists

Lots of work for reviewers

Our Proposal

Challenging for the community to move OpenJDK to a fully social coding model...

… so lets implement the Decorator pattern

Introducing Betterrev...

•  Mirrored OpenJDK repos in Bitbucket •  Community-driven web portal •  “Single-click” setup for newbies •  Automate quality review of patches •  Move discussions to code
