Can Hudson branch promotion get based on project stability?
- by Wayne
Hudson CI server displays stability "weather" which is cool. And it allows one project build to kick off based on the successful build of another. However, how can you make that secondary project dependent additionally on the stability of multiple builds of the first project?
Specifically, project "stable_deploy" needs to only kick off to promote a version to "stable" if project "integrate" with version 8.3.4.1233 has built and tested successfully at least 8 times--in a row. Until then, it's still in integration mode.
IMPORTANT: A significant caveat to this is that a single set of Hudson projects gets used as a "pipeline" to process each new version through to release. So a project may have built successfully 8 times in a rolw but the latest version 8.3.4.1233 may be only the 2 most recent builds. The builds prior to that may be an earlier version.
We're open to completely reorganizing this but the pipeline idea seemed to greatly reduce the amount of manually project creation and deletion. Is there a better way to track version release "pipeline"? In particular, we will have multiple versions in this pipeline simultaneously in the future due to fixes or patches to older versions. We don't see how to do that yet, except to create new pipeline projects for each version which is a real hassle.
Here's some background details:
The TickZoom application has some very complete unit tests some of which simulates real time trading environments. Add to that TickZoom makes elaborate use of parallelization for leveraging multi-core computers. Needless to say, during development of a new version, there can be stability issues during integration testing which get uncovered by running the build and auto tests repeatedly. A version which builds and tests cleanly 8 times in a row without change plus has undergone some real world testing by users can be deemed "stable" and promoted to the stable branch.
Our Hudson projects look like this:
test - Only for testing a build, zero user visibility.
integrate_deploy - Promotes a test project build to integrate branch and makes it
available to public for UA testing.
integrate - Repeatedly builds the integrate branch to determine if it's
stable enough to promote to stable branch. This runs the
builds and test hourly throughout every night.
stable_deploy - Promotes an integrate project build to the stable branch and
makes it public for users who want the latest and greatest.
stable - Builds the stable branch once every night. After 2 weeks of
successful builds (14 builds) it can go to "release candidate".
And so on... it continues with "release candidate" and then "release".
