      BUG#52987: mysqldump fails if umask=0077 · 37b02cd7
      Sven Sandberg authored
      Problem: The test case mysqldump reads a file that must
      be world-readable. The test did not force the file to be
      world-readable, so if the tree was branched with a umask
      of 0077, the test would fail.
      Fix: chmod the file.
      
      
      mysql-test/t/mysqldump.test:
        Added chmod so that the file is guaranteed to be world-readable.

      Bug#52884 mysql-test-run does not work with --debug option · b8af4ab2
      Sergey Glukhov authored
      Server crashes on 64bit linux with 'double free or corruption'
      message, on 32bit mysql-test-run silently fails on bootstrap
      stage. The problem is that FreeState() is called twice
      for init_settings struct in _db_end_ function.
      The fix is to remove superfluous FreeState() call.
      Additional fix:
      fixed discrepancy of result file when
      debug & valgrind options are enabled
      for MTR.

      Patch for Bug#27863 (excessive memory usage for many small queries in a · 6facd4cb
      Alexander Nozdrin authored
      multiquery packet).
      
      Background:
      
        - a query can contain multiple SQL statements;
      
        - the server frees resources allocated to process a query when the
          whole query is handled. In other words, resources allocated to process
          one SQL statement from a multi-statement query are freed when all SQL
          statements are handled.
      
      The problem was that the parser allocated a buffer of size of the whole
      query for each SQL statement in a multi-statement query. Thus, if a query
      had many SQL-statements (so, the query was long), but each SQL statement
      was short, ther parser tried to allocate huge amount of memory (number of
      small SQL statements * length of the whole query).
      
      The memory was allocated for a so-called "cpp buffer", which is intended to
      store pre-processed SQL statement -- SQL text without version specific
      comments.
      
      The fix is to allocate memory for the "cpp buffer" once for all SQL
      statements (once for a query).

      Bug #53450: Crash / assertion "virtual int · 9cbb009b
      Gleb Shchepa authored
                  ha_myisam::index_first(uchar*)") at assert.c:81
      
      Single-table DELETE crash/assertion similar to single-table
      UPDATE bug 14272.
      
      Same resolution as for the bug 14272:
      Don't run index scan when we should use quick select.
      This could cause failures because there are table handlers (like federated)
      that support quick select scanning but do not support index scanning.
      
      
      mysql-test/r/delete.result:
        Test case for bug #53450.
      mysql-test/t/delete.test:
        Test case for bug #53450.

                    ha_myisam::index_first(uchar*)") at assert.c:81
        
        The mysql_delete function has been modified to not to use
        init_read_record_idx instead of init_read_record for the
        quick select.

      Patch for Bug#21818 (Return value of ROW_COUNT() is incorrect · 4333980a
      Alexander Nozdrin authored
      for ALTER TABLE, LOAD DATA).
      
      ROW_COUNT is now assigned according to the following rules:
      
        - In my_ok():
          - for DML statements: to the number of affected rows;
          - for DDL statements: to 0.
      
        - In my_eof(): to -1 to indicate that there was a result set.
      
          We derive this semantics from the JDBC specification, where int
          java.sql.Statement.getUpdateCount() is defined to (sic) "return the
          current result as an update count; if the result is a ResultSet
          object or there are no more results, -1 is returned".
      
        - In my_error(): to -1 to be compatible with the MySQL C API and
          MySQL ODBC driver.
      
        - For SIGNAL statements: to 0 per WL#2110 specification. Zero is used
          since that's the "default" value of ROW_COUNT in the diagnostics area.
      
      sql/protocol.cc:
        Fix a typo.
      sql/sql_class.h:
        - Introduce THD::get_row_count_func() / THD::set_row_count_func();
        - Remove the CF_HAS_ROW_COUNT define
      sql/sql_parse.cc:
        CF_HAS_ROW_COUNT was eliminated.

      Fix for bug#52051: Aggregate functions incorrectly returns · feb03a82
      Ramil Kalimullin authored
            NULL from outer join query
            
            Problem: optimising MIN/MAX() queries without GROUP BY clause
            by replacing the aggregate expression with a constant, we may set it
            to NULL disregarding the fact that there may be outer joins involved.
            
            Fix: don't replace MIN/MAX() with NULL if there're outer joins.
            
            Note: the fix itself is just
            - if (!count)
            + if (!count && !outer_tables)
                set to NULL
            
            The rest of the patch eliminates repeated code to improve speed
            and for easy maintenance of the code.

                Fix for bug#52051: Aggregate functions incorrectly returns
                NULL from outer join query
                  - optimising MIN/MAX() queries without GROUP BY clause by
                replacing them with a constant, take into account that
                there're may be outer joins involved.
                  - repeated code for MIN/MAX optimization in the opt_sum_query()
                eliminated by introducing new functions that read MIN/MAX values
                using index and combining MIN/MAX cases to one.

      Large number of changes to support building RPMs using CMake, along · 240176bf
      Jonathan Perkin authored
      with other merges from the old distribution-specific spec file.
      
       - update copyright notices
      
       - remove __os_install_post override, it was only necessary as a
         hack to build debuginfo packages - now that we no longer make
         them we can revert to the distribution macro which likely has
         other useful bits we might want
      
       - remove _unpackaged_files_terminate_build override, we want to
         know of any orphaned files
      
       - include native distribution support
      
       - no longer build separate debuginfo RPMs, instead just include
         debug/symbols in all binaries, which is more useful for support
      
       - include support for building commercial RPMs, requires a
         commercial source tree
      
       - remove cluster RPM support, we don't build them from this
         source tree
      
       - use CMake for building, and update package lists to match the
         new install layout/files.  Remove any options which were only
         useful for automake builds (e.g. yassl/zlib).
