Kristian Waagan updated DERBY-4040: ----------------------------------- Attachment: derby-4040-2a-backport.diff Attached the diff for the backport, 'derby-4040-2a-backport.diff'. I had to do a manual merge, as the method InputStreamUtil.skipFully doesn't exist on the 10.4 and 10.3 branches. Instead of using that method, I simply chose to use InputStream.skip. Regression tests ran successfully. Committed to the 10.4 branch with revision 745571. > SQLChar.getLength returns wrong length for some data values > ----------------------------------------------------------- > > Key: DERBY-4040 > URL: https://issues.apache.org/jira/browse/DERBY-4040 > Project: Derby > Issue Type: Bug > Components: SQL > Affects Versions: 10.3.3.1, 10.4.2.0, 10.5.0.0 > Reporter: Kristian Waagan > Assignee: Kristian Waagan > Fix For: 10.5.0.0 > > Attachments: derby-4040-1a-SQLChar_length_and_test.diff, > derby-4040-1a-SQLChar_length_and_test.stat, derby-4040-2a-backport.diff > > > SQLChar.getLength() returns the wrong length of the data value in some cases. > For the bug to be triggered, the value must contain characters that are > represented by two or three bytes, and Derby must store the value as a stream. > In my ad-hoc testing, I found that a value of length 10886 with CJK > characters doesn't trigger the bug, but 10887 does trigger the bug. Further, > for a range of lengths the bug can also been observed for CLOB columns (when > doing 'select length(clobcolumn)'). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
