Subject [jira] [Created] (CASSANDRA-5496) Fix SemanticVersion.isSupportedBy patch/minor handling
Date Thu, 18 Apr 2013 16:33:17 GMT
Aleksey Yeschenko created CASSANDRA-5496:
--------------------------------------------

             Summary: Fix SemanticVersion.isSupportedBy patch/minor handling
                 Key: CASSANDRA-5496
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5496
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.2.4
            Reporter: Aleksey Yeschenko
            Assignee: Aleksey Yeschenko
            Priority: Minor
             Fix For: 1.2.5


Currently we use the following logic:
{noformat}
return major == version.major && minor <= version.minor && patch <=
version.patch;
{noformat}

This requires both minor and patch vers to be less or equal, which means that, for example,
'3.0.3' is not supported by '3.1.2', because, while 0 <= 1 (minor), 3 > 2 (patch). This
is clearly not the intent since 3.1.2 > 3.0.3.

CQL3 doc: "Minor version increments occur when new, but backward compatible, functionality
is introduced". Hence '3.0.3' is supposed to be supported by '3.1.0'.

This doesn't really affect 1.2, but breaks a lot of trunk dtests post CASSANDRA-3919.
