--
[~jay.zhuang] , [~Yarnspinner] , thanks for fixing this problem and writing the
test.
I checked both patches, they are both good. Perhap's Jay's approach of assuming
50,000 iterations for duration tests is slightly preferable since that was the
old behavior.

[jira] [Commented] (CASSANDRA-11323) When node runs out of commitlog space you get poor log information

Ariel Weisberg commented on CASSANDRA-11323:
Thanks [~BorisO]. 2.2 is getting critical bug fixes only so this can only go
into 3.0, 3.11, and trunk. Can you make patches for those three versions?
The log message could probably be more informative like "%d bytes required for
next commit log segment, but only %d bytes available. " It also seems like we
want this to occur for everything except ignore? Or maybe even then? I think
the only concern would be if we log it repeatedly when ignore is the policy due
to some high volume exception. You could use the NoSpamLogger to avoid that
issue.
Another issue is that this error is generated even if the exception is
something else. So we should probably have the log message specify that free
space is not necessarily the cause of this exception. And if we are getting
even more transparent, maybe we should specify the commit log directory path
just so people at a glance know what volume is in use.

[jira] [Commented] (CASSANDRA-11939) Read and Write Latency columns are swapped in proxyhistograms vs cfhistograms

Ariel Weisberg commented on CASSANDRA-11939:
Thanks [~adeb0001]. I will try and look at the patches this week.
I don't think we have the clearest policy about modifying nodetool output, and
2.2 is getting critical bug fixes only. Mostly I just need to figure out
where/if we can make this change.

bq. Another option would probably to generate two versions of the config.yml
yeah that sounds better I think, let me know if you want me to do those final

> The current CircleCI config could use some cleanup and improvements. First of

> 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/be25579d-3cbb-4258-9e19-b1f571873850]
> with start_ jobs being triggers needed manual approval for starting the

[jira] [Commented] (CASSANDRA-14554) LifecycleTransaction encounters ConcurrentModificationException when used in multi-threaded context

{quote}If you are confident that child transactions are the best solution I'm
not opposed but the same can be achieved with a synchronized transaction and a
reference to the txn kept by the writers.
{quote}
Well, we've seen a few edge cases now where the synchronised version was
difficult to reason about and left problematic behaviours, and it might be more
brittle in future.
But if you're confident you can resolve the remaining issues through
synchronisation (and we can establish if trunk is (effectively) synchronised,
or should be), that has the advantage of already being (almost) done.
