Michael Semb Wever commented on CASSANDRA-15520:
------------------------------------------------
Jenkins uses build scripts already, those in
https://github.com/apache/cassandra-builds/tree/master/build-scripts
AFAIK these were added before CircleCI, and because CircleCI had it's own
challenges and advantages they weren't re-used. [~spod] knows more on this.
It would be nice to a) move these scripts in-tree (eg into a {{`.ci`}} folder),
and b) bring them up to scratch for CircleCI.
I suspect doing this will also give us a chunk of the work required to
parallelise the dtests in Jenkins :)

> URL: https://issues.apache.org/jira/browse/CASSANDRA-15520
> Project: Cassandra
> Issue Type: Improvement
> Components: Build
> Reporter: David Capwell
> Assignee: David Capwell
> Priority: Normal
>
> CircleCI is one of the main tools we use for build and test, but there is
> also ASF Jenkins and many people run builds in their own companies as well.
> It would be nice to refactor the existing CircleCI yaml to delegate to a set
> of scripts which could be reused by other build systems.
> I feel that we could do the following directory layout
> {code}
> ci - top level directory containing all scripts
> - <test type : unit, distributed> - directory containing the different build
> steps
> - <test name : eg. unit, jvm-dtest, long, etc.> - a single build with
> the required steps to run it
> - split.sh - script which takes in a output file to write to and
> dumps out all test cases (not partitioned)
> - run_partition.sh - script which takes a partitioned list of tests
> and executes the build (does not move around artifacts)
> {code}
> This would allow CircleCI and Jenkins to run the same way, but also acts as
> documentation for how to run some of the tests (jvm-dtest and python dtest
> upgrade tests take more time to figure out how to run).
> CircleCI would also be simpler as it would mostly be the circle ci specific
> logic (partition tests, move code/test results around, etc.) calling these
> scripts.
