      Bug #22344: InnoDB keys act strange on datetime vs timestamp comparison · c35ceeca
      unknown authored
       Ignoring error codes from type conversion allows default (wrong) values to
       go unnoticed in the formation of index search conditions.
       Fixed by correctly checking for conversion errors.

      Fixed bug #25407. · c15b2e41
      unknown authored
      The bug could cause choosing a sub-optimal execution plan for 
      a single-table query if a unique index with many null keys were 
      defined for the table. 
      It happened because the code of the check_quick_keys function 
      made an assumption that any key may occur in an unique index 
      only once. Yet this is not true for keys with nulls that may 
      have multiple occurrences in the index.

      Fix bug#23293 "readline detection broken on NetBSD": · 7a71303c
      unknown authored
      Its root cause is a difference between the "readline" and "libedit" (header files)
      definitions of "rl_completion_entry_function", where the "libedit" one is wrong anyway:
      This variable is used as a pointer to a function returning "char *",
      but "libedit" declares it as returning "int" and then adds casts on usage.
      
      Change it to "CPFunction *" and get rid of the casts.

        Fix bug#23293 "readline detection broken on NetBSD":
        
        Now that the "libedit" header files declares "rl_completion_entry_function" correctly,
        it need not be cast on usage, and "no_completion()" can be declared to return "char *".

      BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join · fbc16a85
      unknown authored
       Two problems here:
      
       Problem 1:
      
       While constructing the join columns list the optimizer does as follows:
        1. Sets the join_using_fields/natural_join members of the right JOIN 
         operand.
        2. Makes a "table reference" (TABLE_LIST) to parent the two tables.
        3. Assigns the join_using_fields/is_natural_join of the wrapper table
         using join_using_fields/natural_join of the rightmost table
        4. Sets join_using_fields to NULL for the right JOIN operand.
        5. Passes the parent table up to the same procedure on the upper 
         level.
      
       Step 1 overrides the the join_using_fields that are set for a nested 
       join wrapping table in step 4.
       Fixed by making a designated variable SELECT_LEX::prev_join_using to 
       pass the data from step 1 to step 4 without destroying the wrapping 
       table data.
      
       Problem 2:
      
       The optimizer checks for ambiguous columns while transforming 
       NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no
       distinction between columns that are used in the generated join
       condition (where ambiguity can be checked) and the other columns
       (where ambiguity can be checked only when resolving references
       coming from outside the JOIN construct itself).
       Fixed by allowing the non-USING columns to be present in multiple 
       copies in both sides of the join and moving the ambiguity check 
       to the place where unqualified references to the join columns are
       resolved (find_field_in_natural_join()).

      Bug #25551: inconsistent behaviour in grouping NULL, depending on index type · d01ec5e7
      unknown authored
       The optimizer takes away columns from GROUP BY/DISTINCT if they constitute
       all the parts of an unique index.
       However if some of the columns can contain NULLs this cannot be done 
      (because an UNIQUE index can have multiple rows with NULL values).
       Fixed by not using UNIQUE indexes with nullable columns to remove
       grouping columns from GROUP BY/DISTINCT.

      Bug #25643: SEC_TO_TIME function problem · 3cb3a9a1
      unknown authored
       Checking for NULL before calling the val_xxx()
       methods only checks for such arguments that are 
       known to be NULLs at compile time. 
       The arguments that may or may not contain
       NULLs (e.g. function calls and possibly others)
       are not checked at all.
       Fixed by first calling the val_xxx() method and
       then checking for null in SEC_TO_TIME().
       In addition QUARTER() was not returning 0 (as all the 
       val_int() functions do when processing a NULL value).

      Fixed bug #24653. · da561a80
      unknown authored
      The bug report has demonstrated the following two problems.
      1. If an ORDER/GROUP BY list includes a constant expression being 
      optimized away and, at the same time, containing single-row
      subselects that return more that one row, no error is reported.
      Strictly speaking the standard allows to ignore error in this case.
      Yet, now a corresponding fatal error is reported in this case.
      2. If a query requires sorting by expressions containing single-row
      subselects that, however, return more than one row, then the execution
      of the query may cause a server crash. 
      To fix this some code has been added that blocks execution of a subselect
      item in case of a fatal error in the method Item_subselect::exec.
      
      
      mysql-test/r/subselect.result:
        Added a test cases for bug #24653.

        Added a check for fatal error after reading the next row from the table
        in the function find_all_keys.

      sql/sql_select.cc:

        Added a check to verify that any constant expression used
        in ORDER BY and/or GROUP BY lists which is optimized away
        does not contain subselects returning more than one row.
        If it does a fatal error is reported.

      BUG#25530 --with-readline fails with commercial source packages · 6cfffb50
      unknown authored
      
      BUILD/SETUP.sh:
        BUG#25530 --with-readline fails with commercial source packages
        
        The compile-* scripts should not use --with-readline explicitly when no readline is present.
      configure.in:
        BUG#25530 --with-readline fails with commercial source packages
        
        Configuring --with-readline should fail when libreadline is not bundled.
        A system libreadline is only used when there is a bundled libreadline too, so the commercial source code isn't linked with GPL libreadline by accident.
