Subject [jira] Updated: (DBCP-5) [dbcp] PoolGuardConnectionWrapper violates close() contract
Date Mon, 10 Jul 2006 05:35:32 GMT
     [ http://issues.apache.org/jira/browse/DBCP-5?page=all ]

Phil Steitz updated DBCP-5:
---------------------------

    Bugzilla Id:   (was: 39069)
    Fix Version: 1.3

> [dbcp] PoolGuardConnectionWrapper violates close() contract
> -----------------------------------------------------------
>
>          Key: DBCP-5
>          URL: http://issues.apache.org/jira/browse/DBCP-5
>      Project: Commons Dbcp
>         Type: Bug

>  Environment: Operating System: All
> Platform: All
>     Reporter: Derek Park
>      Fix For: 1.3

>
> org.apache.commons.dbcp.PoolingDatasource.PoolGuardConnectionWrapper.close()
> violates the Connection.close() contract specified in the Java 1.5 API.  The
> current API specifies that calling close() on an already-closed connection is a
> no-op.  (Blame Sun for the bug.  The API didn't used to say that.)  
> PoolGuardConnectionWrapper.close() first calls checkOpen() which throws an
> exception if close() has already been called.  Clearly that's not a no-op.
> The simplest fix is to change the first line in the close() method from this:
> checkOpen();
> to this:
> if (this.delegate == null) return;
> As of today (2006-03-22) this bug is in the latest SVN source (and has been in
> previous versions as well).
> DelegatingConnection and PoolingConnection don't seem (from a quick glance) to
> have this problem.
