Subject [jira] [Commented] (CASSANDRA-10162) Test regression for cqlsh_tests.TestCqlsh.test_describe
Date Mon, 24 Aug 2015 12:36:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14709182#comment-14709182

Sylvain Lebresne commented on CASSANDRA-10162:
----------------------------------------------

I think the best fix here is to make sure the {{decompose}} method for sets and maps always
sort it's input if needs be. I've pushed a patch to do so [here|https://github.com/pcmanus/cassandra/commits/10162].
It fixes the test in question though I'm still waiting on CI results to make sure it doesn't
break anything else.

> The regression is due to the commit db782362aaf25214a94c393b20cdbade829c5291 from CASSANDRA-6717,
the one that switched to using frozen sets and maps in schema tables.
> The problem is that after this patch, the maps and sets are not sorted anymore, which
confuse the test in question. Now, we document that maps and sets are sorted, and that should
be true for frozen ones too so it's a legit bug imo, not a problem of the test.
