Subject [jira] Commented: (DERBY-815) Prevent unneeded object creation and excessive decoding in parseSQLDTA_work()
Date Sun, 30 Jul 2006 17:14:17 GMT
    [ http://issues.apache.org/jira/browse/DERBY-815?page=comments#action_12424411 ] 
            
Kathey Marsden commented on DERBY-815:
--------------------------------------

My  review comment about hiding CliParam  and handling of clearing parameters etc from DRDAConnThread
 is my only comment for now on this patch.  I do not really have my head around all the cases
and handling for parameter setting and clearing etc, so look forward to hearing review comments
from others on the patch to understand better.  My feeble mind might  also be able to sort
it out better once this change is made.   Can  we uncheck patch available or would you like
more comments on this version?

Also I wanted to mention that if you have higher urgency items for 10.2, don't feel compelled
to jump on changing this right away.  It could easily go into the maintenance branch after
releas.  I just picked it up as my patch for the week.  


Thanks 

Kathey
