[ http://issues.apache.org/jira/browse/DERBY-974?page=comments#action_12421146 ] Michael Hackett commented on DERBY-974: ---------------------------------------
OK, I'll give it a try. I got the trunk source and all the dependencies and managed to get the tests running (after a short struggle). I'll try to pick it back up early next week and add a test and look at writing a fix. > ClientDriver can lose some connection properties > ------------------------------------------------ > > Key: DERBY-974 > URL: http://issues.apache.org/jira/browse/DERBY-974 > Project: Derby > Issue Type: Bug > Components: Network Client > Affects Versions: 10.1.2.1, 10.1.2.2 > Environment: Linux, Sun JRE 1.5 > Reporter: Michael Hackett > Priority: Minor > Attachments: ClientDriver.java-diff, PropertiesTest.java > > > Internally, the ClientDriver class's appendDatabaseAttributes() method uses > keys() on the connection properties to get a list of the property names. > However, this misses any properties in the default set. The correct method > for a Properties object is propertyNames(). This will return the same type of > object as keys(), but will include all properties. > (It is unfortunate that Sun chose to make Properties a subclass of Hashtable, > instead of giving Properties a Hashtable, as the former exposes too much > implementation.) > The fix is to simply replace calls to keys() on all Property objects to use > propertyNames(). A quick search revealed that this is not the only place in > the code base where this is done, so a more thorough scan should be made. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
