      Bug #32036: EXISTS within a WHERE clause with a UNION · 3315addf
      unknown authored
        crashes MySQL 5.122
      There was a difference in how UNIONs are handled
      on top level and when in sub-query.
      Because the rules for sub-queries were syntactically
      allowing cases that are not currently supported by
      the server we had crashes (this bug) or wrong results
      (bug 32051).
      Fixed by making the syntax rules for UNIONs match the 
      ones at top level.
      
      These rules however do not support nesting UNIONs, e.g.
      (SELECT a FROM t1 UNION ALL SELECT b FROM t2) 
       UNION
      (SELECT c FROM t3 UNION ALL SELECT d FROM t4)
      Supports for statements with nested UNIONs will be
      added in a future version.

      Fixed bug #32556: assert in "using index for group-by" : · d408a401
      unknown authored
                        is_last_prefix <= 0, file .\opt_range.cc.
      
      SELECT ... GROUP BY bit field failed with an assertion if the
      bit length of that field was not divisible by 8.
      
      
      
      sql/key.cc:
        Fixed bug #32556.
        Copying of "uneven" bits of a bit field was duplicated in the
        key_copy() and in the Field_bit::get_key_image().
        So, instead of copying of the rest of a bit field, 
        Field_bit::get_key_image() copied "uneven" bits to key image again,
        and the lowest field byte was not copied to key at all.
        
        Duplicated code has been removed from the key_copy function.

      Bug #30788: Inconsistent retrieval of char/varchar · f3637af4
      unknown authored
      Index lookup does not always guarantee that we can
      simply remove the relevant conditions from the WHERE
      clause. Reasons can be e.g. conversion errors, 
      partial indexes etc. 
      The optimizer was removing these parts of the WHERE 
      condition without any further checking.
      This leads to "false positives" when using indexes.
      Fixed by checking the index reference conditions
      (using WHERE) when using indexes with sub-queries.

      Bug #32400: Complex SELECT query returns correct result · 5a49b5f0
      unknown authored
       only on some occasions
      
      Referencing an element from the SELECT list in a WHERE 
      clause is not permitted. The namespace of the WHERE
      clause is the table columns only. This was not enforced
      correctly when resolving outer references in sub-queries.

      Bug#31048: Many nested subqueries may cause server crash. · 54393c2f
      unknown authored
      This bug is actually two. The first one manifests itself on an EXPLAIN
      SELECT query with nested subqueries that employs the filesort algorithm.
      The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve
      some temporary structures for explain. As a side-effect of this values of
      nested subqueries weren't cached and subqueries were re-evaluated many
      times. Each time buffer for filesort was allocated but wasn't freed because
      freeing occurs at the end of topmost SELECT. Thus all available memory was
      eaten up step by step and OOM event occur.
      The second bug manifests itself on SELECT queries with conditions where
      a subquery result is compared with a key field and the subquery itself also
      has such condition. When a long chain of such nested subqueries is present
      the stack overrun occur. This happens because at some point the range optimizer
      temporary puts the PARAM structure on the stack. Its size if about 8K and
      the stack is exhausted very fast.
      
      Now the subselect_single_select_engine::exec function allows subquery result
      caching when the UNCACHEABLE_EXPLAIN flag is set.
      Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun
      function for stack checking purposes to prevent server crash.

      Fix for bug #32221: bug25714, mytest, mysql_client_test complaints and · 53dfb5a9
      unknown authored
      crashes.
      
      MySQL distributions contain a number of programs that are used only by
      the MySQL test suite internally, i.e. they are not indended to be
      invoked directly by a user. As a result, such programs are not
      documented, do not have any built-in help or proper error reporting,
      which may confuse users.
      
      This patch fixes the problem with the following changes:
      - mytest, libmysqltest and all references to them were removed from the
      distribution since they are not used anymore
      - bug25714 now displays an error message when run with incorrect
      arguments or with the --help option
      - mysql_client_test now does not call abort() in case of errors,
      instead it does a clean exit() with a proper error status.
