Subject [jira] [Commented] (CASSANDRA-10034) Windows utest 3.0: testDateCompatibility failing intermittently
Date Tue, 11 Aug 2015 20:11:45 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10034?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14682401#comment-14682401
] 

Paulo Motta commented on CASSANDRA-10034:
-----------------------------------------

Wasn't able to reproduce the intermittency locally. My guess is that sometimes {{toUnixTimestamp(now())}}
is mapping to the same millisecond in the first and second statements, so in the second statement
{{b < toUnixTimestamp(now())}} sometimes returns 0 entries:

{noformat}
INSERT INTO %s (a, b, c, d) VALUES (0, toUnixTimestamp(now()), toTimestamp(now()), toTimestamp(now()))
SELECT * FROM %s WHERE a=0 AND b < toUnixTimestamp(now())
{noformat}

So I basically replaced {{b < toUnixTimestamp(now())}} in the second statement by {{b <=
toUnixTimestamp(now())}}, to guarantee at least one entry will be returned in case {{toUnixTimestamp(now())}}
maps to the same millisecond.
