Stefan Podkowinski commented on CASSANDRA-14806:
------------------------------------------------
I've now basically rewritten the CircleCI config to make heavily use of
parameters to avoid redundant copy and pasting of script snippets. Combined
with job approvals, we can now have a broader selection of tests. So far I've
added: ant long-test, test-burn, cql-test, test-compression, stress-test,
fqltool-test. Cqlsh dtests will be added in CASSANDRA-14298.
Unfortunately I wasn't able to solve the requirement for not having to manually
edit the config for switching between high/free resource settings. CircleCI
support was so kind to look at the issue and latest config, but wasn't able to
advise a solution either. So I guess we still have to live with that situation
for a while.
> CircleCI workflow improvements and Java 11 support

> Key: CASSANDRA-14806
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14806
> Project: Cassandra
> Issue Type: Improvement
> Components: Build, Testing
> Reporter: Stefan Podkowinski
> Assignee: Stefan Podkowinski
> Priority: Major
>
> The current CircleCI config could use some cleanup and improvements. First of
> all, the config has been made more modular by using the new CircleCI 2.1
> executors and command elements. Based on CASSANDRA-14713, there's now also a
> Java 11 executor that will allow running tests under Java 11. The {{build}}
> step will be done using Java 11 in all cases, so we can catch any regressions
> for that and also test the Java 11 multi-jar artifact during dtests, that
> we'd also create during the release process.
> The job workflow has now also been changed to make use of the [manual job
> approval|https://circleci.com/docs/2.0/workflows/#holding-a-workflow-for-a-manual-approval]
> feature, which now allows running dtest jobs only on request and not
> automatically with every commit. The Java8 unit tests still do, but that
> could also be easily changed if needed. See [example
> workflow|https://circleci.com/workflow-run/08ecb879-9aaa-4d75-84d6-b00dc9628425]
> with start_ jobs being triggers needed manual approval for starting the
> actual jobs.
> There was some churn in manually editing the config for paid and non-paid
> resource tiers before. This has been mostly mitigated now by using project
> settings instead, for overriding lower defaults (see below) and scheduling
> dtests on request, which will only run on paid accounts nonetheless, so we
> use high settings for these right away. The only issue left is the question
> how we may be able to dynamically adjust the {{resource_class}} and
> {{parallelism}} settings for unit tests. So at this point, the CircleCI
> config will work for both paid and non-paid by default, but paid accounts
> will see slower unit test results, as only medium instances are used (ie.
> 15min instead of 4min).
> Attention CircleCI paid account users: you'll have to add
> "{{CCM_MAX_HEAP_SIZE: 2048M}}" and "{{CCM_HEAP_NEWSIZE: 512M}}" to your
> project's environment settings or create a context, to override the lower
> defaults for free instances!
