LP:778917 - Valgrind warnings in maria-5.3-mwl34

        Details

        • Type: Bug
        • Status: Closed
        • Priority: Critical

          Description

          A simple RQG test produced the misc valgrind warnings from the attached file. Most seem to be related to handling malformed datetimes, however note that there are 2 warnings about innodb and myisam using an undefined value for some internal operations.

          Let me know if individual test cases are required – I can provide the RQG grammar and/or MTR.

                Re: Valgrind warnings in maria-5.3-mwl34
                I looked at the valgrind result, but unfortunately without the test cases that caused the failures there is not much I can do.
                So please provide the RQG and MTR grammar so that I can test this myself.

                I think that I manged to fix a couple of the valgrind errors as part of other bug fixes, but looking at the log there are some left that would be nice to get rid off.

                Unsimplified test case. When run without valgrind, causes the following crash as well:

                The problem was using a wrong (too short) strong to column_add().
                I have now added a check to detect this + a test case.
