      Bug #41383 Test commit1_innodb fails with binlog-format=row · 5753307a
      Andrei Elkin authored
      The test explicitly warned on existence of a bug in its 27th part.
      The expected values of prepare and commit counters changed, corrected, by
      fixes to bug#40221.
      Notice, that binlog does not have to register for a statement with
      the statement binlog-format because the statement rollback does not need
      to do anything in that mode. It's not so with the ROW format which was
      bug#40221 concern.
      
      Fixed with correcting the expected values of the mentioned counters and
      explained that with comments in the test.
      
      mysql-test/include/commit.inc:
        Removing `Sic' that warned on a bug (The one is bug#40221).
        Correcting the expected values of prepare and commit counters due to fixes to bug#40221.
      mysql-test/r/commit_1innodb.result:
        results changed.

      Bug #40761: Assert on sum function on · ffe23f0e
      Gleb Shchepa authored
                  IF(..., CAST(longtext AS UNSIGNED), signed_val)
                  (was: LEFT JOIN on inline view crashes server)
      
      Select from a LONGTEXT column wrapped with an expression
      like "IF(..., CAST(longtext_column AS UNSIGNED), smth_signed)"
      failed an assertion or crashed the server. IFNULL function was
      affected too.
      
      LONGTEXT column item has a maximum length of 32^2-1 bytes,
      at the same time this is a maximum possible length of any
      MySQL item. CAST(longtext_column AS UNSIGNED) returns some
      unsigned numeric result of length 32^2-1, so the result of
      IF/IFNULL function of this number and some other signed number
      will have text length of (32^2-1)+1=32^2 (one byte for the
      minus sign) - there is integer overflow, and the length is
      equal to zero. That caused assert/crash.
      
      The bug has been fixed by the same solution as in the CASE
      function implementation.

        Added test case for bug #40761.

        1. Item_func_case::agg_str_lengths method has been moved
           to the Item_func superclass.
        2. Item_func_ifnull/Item_func_if::fix_length_and_dec methods
           have been updated to calculate max_length, decimals and
           unsigned flag like Item_func_case.

      Bug#33812: mysql client incorrectly parsing DELIMITER · d84690c9
      Chad MILLER authored
      Fix parsing of mysql client commands, especially in relation to
      single-line comments when --comments was specified.
      
      This is a little tricky, because we need to allow single-line
      comments in the middle of statements, but we don't want to allow
      client commands in the middle of statements. So in
      comment-preservation mode, we go ahead and send single-line
      comments to the server immediately when we encounter them on their
      own. 
      
      This is still slightly flawed, in that it does not handle a
      single-line comment with leading spaces, followed by a client-side
      command when --comment has been enabled. But this isn't a new
      problem, and it is quite an edge condition. Fixing it would require
      a more extensive overall of how the mysql client parses commands.
