[ http://issues.apache.org/jira/browse/DERBY-246?page=all ]
Kathey Marsden updated DERBY-246:
---------------------------------
Attachment: DERBY-246_irc_6_3_2005
Philip reviewed my change for DERBY-246 and commented that an instance of if
(!open_ && !availableForReuse_)
could be changed to
if (isPhysicallyClosed())
* Talked about how in the client the public api calls such as close() and
next() have tracing but the corresponding internal calls closeX() and nextX()
don't.
Internal code should call closeX() instead of close().
* Talked about general approach of fix for DERBY-246, to rip out as much of
the XA state in the client as possible.
