3 | 51 | Loïc Dachary | Backporting and the maintenance of a stable release begins when a new "stable Ceph release":http://ceph.com/docs/master/releases is published. Commits from the master branch are cherry-picked to the stable branch and run through integration and upgrade tests. After a few weeks a "point release":http://ceph.com/docs/master/releases is published. This repeats until the "the stable release is retired":http://ceph.com/docs/master/releases. Backporting is focused on fixing bugs and development on the master branch is expected to add new features but both share the "same workflow":http://ceph.com/docs/master/dev/development-workflow/. |

81 | 15 | Loïc Dachary | |
82 | 38 | Loïc Dachary | h4. Publish a stable release |
83 | |||
84 | 39 | Loïc Dachary | * Study https://github.com/ceph/ceph-build/ and http://jenkins.ceph.com/ to figure out how it is used to update http://ceph.com/debian-hammer/ and http://ceph.com/rpm-hammer/ |
85 | 40 | Loïc Dachary | * The jenkins job is http://jenkins.ceph.com/job/ceph/ and requires some setup |
86 | * The "ceph-jenkins-build":https://github.com/alfredodeza/ceph-jenkins-build/tree/master/ceph ansible setup does a bunch of things like "changing version numbers, creating a tag and pushing to the Jenkins GIT repository":https://github.com/alfredodeza/ceph-jenkins-build/blob/master/ceph/tasks/setup.yml |
||
87 | * once that tag is created that can be used to trigger a build in the jenkins ui when the build is completed you are required to run a bunch of scripts in the jenkins server they sign and re-index the repositories and then synchronize them with ceph/(rpm|debian)-$release. Those scripts need to be edited by hand depending on the type of release and where you are pushing them to (e.g. testing vs firefly vs hammer) |
||
88 | * for hammer a new repository was created by hand and it is "documented as a script":https://gist.github.com/alfredodeza/b8f8b94ea795f1a7169b |
