      Backport of Igor's patch for Bug#27362, March 22 2007. · 992fc6b2
      unknown authored
      Fixed bug #27362: crash at evaluation of IN predicate when one
      of its argument happened to be a decimal expression returning
      the NULL value.
      The crash was due to the fact the function in_decimal::set did
      not take into account that val_decimal() could return 0 if 
      the decimal expression had been evaluated to NULL.  
      
      
      mysql-test/r/func_in.result:
        Added a test case for bug #27362.
      mysql-test/t/func_in.test:
        Added a test case for bug #27362.

      The test fails, and it shouldn't.
      
      
      mysql-test/r/information_schema.result:
        The query to generate this list is pretty bogus in any case.  Listing 
        all columns of a particular type tells us nothing at all.

      Bug #27231: Server crash when dumping into outfile with long FIELDS ENCLOSED BY option · d59272fb
      unknown authored
      - Problem: data separators were copied to a fixed-size buffer
        on the stack; memcpy was used, without bounds checking; a
        server crash could result if long FIELDS ENCLOSED BY, etc.,
        was given
      - Fix: write the separators directly, instead of copying to
        a buffer first (in select_export::send_data())
      
      
      sql/sql_class.cc:
        In select_export::send_data(), write data separators
        directly, instead of copying into a fixed-size memory
        buffer before writing.  This avoids a buffer overflow
        when very large separators are specified.

      Bug#20166 mysql-test-run.pl does not test system privilege tables creation · 77fccd03
      unknown authored
       - Build sql files for netware from the mysql_system_tables*.sq files
       - Fix comments about mysql_create_system_tables.sh
       - Use mysql_install_db.sh to create system tables for mysql_test-run-shell
       - Fix mysql-test-run.pl to also look in share/mysql for the msyql_system*.sql files
      
      Changeset coded today by Magnus Svensson, just the application to 5.0.38 is by Joerg Bruehe.

        Added netware/init_db.sql netware/test_db.sql to the ignore list
      mysql-test/install_test_db.sh:
        Use mysql_install_db from install_test_db(which is used by mysql-test-run-shell)
        to install the system tables
      mysql-test/mysql-test-run.pl:
        Look for the mysql_system_tables*.sql also in share/mysql
      netware/Makefile.am:
        Build netware/init_db.sql and netware/test_db.sql from
        the sources in scripts/msyql_system_tables*.sql
      scripts/make_binary_distribution.sh:
        netware/init_db.sql and netware/test_db.sql are now built by the Makefiles
        from the scripts/mysql_system_tables*.sql files

        because it will be missing when the tests are run during release build or by a customer.

      Fix for bug #25966 "2MB per second endless memory consumption after LOCK · cdd2a2e4
      unknown authored
      TABLE ... WRITE".
      
      Memory and CPU hogging occured when connection which had to wait for table
      lock was serviced by thread which previously serviced connection that was
      killed (note that connections can reuse threads if thread cache is enabled).
      One possible scenario which exposed this problem was when thread which
      provided binlog dump to replication slave was implicitly/automatically
      killed when the same slave reconnected and started pulling data through
      different thread/connection.
      The problem also occured when one killed particular query in connection
      (using KILL QUERY) and later this connection had to wait for some table
      lock.
      
      This problem was caused by the fact that thread-specific mysys_var::abort
      variable, which indicates that waiting operations on mysys layer should
      be aborted (this includes waiting for table locks), was set by kill
      operation but was never reset back. So this value was "inherited" by the
      following statements or even other connections (which reused the same
      physical thread). Such discrepancy between this variable and THD::killed
      flag broke logic on SQL-layer and caused CPU and memory hogging.
      
      This patch tries to fix this problem by properly resetting this member.
      
      There is no test-case associated with this patch since it is hard to test
      for memory/CPU hogging conditions in our test-suite.
      
      
      sql/mysqld.cc:
        We should not forget to reset THD::mysys_var::abort after kill operation
        if we are going to use thread to which this operation was applied for
        handling of other connections.
      sql/sp_head.cc:
        We should not forget to reset THD::mysys_var::abort after kill operation
        if we are going to use thread to which this operation was applied for
        handling of further statements.

        We should not forget to reset THD::mysys_var::abort after kill operation
        if we are going to use thread to which this operation was applied for

      In 5.* versions memory hogging was added to CPU hogging. Moreover in
      those versions the problem also occured when one killed particular query
      in connection (using KILL QUERY) and later this connection had to wait for
      some table lock.

      BUG#26881 - Large MERGE tables report incorrect specification when no · 969b7165
      unknown authored
                  differences in tables
      Certain merge tables were wrongly reported as having incorrect definition:
      - Some fields that are 1 byte long (e.g. TINYINT, CHAR(1)), might
        be internally casted (in certain cases) to a different type on a
        storage engine layer. (affects 4.1 and up)
      - If tables in a merge (and a MERGE table itself) had short VARCHAR column (less
        than 4 bytes) and at least one (but not all) tables were ALTER'ed (even to an
        identical table: ALTER TABLE xxx ENGINE=yyy), table definitions went ouf of
        sync. (affects 4.1 only)
      
      This is fixed by relaxing a check for underlying conformance and setting
      field type to FIELD_TYPE_STRING in case varchar is shorter than 4
      when a table is created.
      
      
      myisam/mi_create.c:
        Added a comment.
      mysql-test/r/merge.result:
        A test case for bug#26881.
      mysql-test/t/merge.test:
        A test case for bug#26881.
      sql/ha_myisam.cc:
        Relaxed some checks performed by check_definition():
        As comparing of fulltext keys (and key segments) is not yet implemented,
        only return an error in case one of keys is fulltext and other is not.
        Otherwise, if both keys are fulltext, accept them as is.
        
        As comparing of spatial keys (and key segments) is not yet implemented,
        only return an error in case one of keys is spatial and other is not.
        Otherwise, if both keys are spatial, accept them as is.
        
        A workaround to handle situation when field is casted from FIELD_SKIP_ZERO
        to FIELD_NORMAL. This could happen only in case field length is 1 and row
        format is fixed.
      sql/sql_parse.cc:
        When a table that has varchar field shorter than 4 is created, field type is
        set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter
        table, field type is changed to FIELD_TYPE_STRING (see Field_string::type).
        That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might
        be shifted by alter table, in other words alter table doesn't create 100%
        equal table definition.
        
        This is usually not a problem, since when a table is created/altered,
        definition on a storage engine layer is based on one that is passed from
        sql layer. But it is a problem for merge engine - null_bit is shifted when
        a table (merge or underlying) is altered.
        
        Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter
        than 4 when a table is created as it is done in Field::type.
