      Support for character set conversion in binary protocol: another go · 093d6292
      unknown authored
      after Monty's review.
      - Item_param was rewritten.
      - it turns out that we can't convert string data to character set of
        connection on the fly, because they first should be written to the binary
        log.
        To support efficient conversion we need to rewrite prepared statements
        binlogging code first.
      
      
      include/my_global.h:
        Macro swap(a, b, c) was renamed to resolve name conflict with
        String::swap() method.
      include/my_sys.h:
        Added declaration of escape_string_for_mysql()
      include/mysql_com.h:
        Removed and moved back: a macro which is visible to libmysql user but
        has sence only in prepared statement protocol implementation.
      isam/_search.c:
        swap -> swap_variables
      isam/test2.c:
        swap -> swap_variables
      libmysql/libmysql.c:
        - sub_escape_string moved to mysys/charset.c to be visible in sql/
        - few cleanups
      myisam/mi_test2.c:
        swap -> swap_variables
      mysys/charset.c:
        sub_escape_string was moved from libmysql.c to be able to use it in sql/
        code.
      mysys/my_chsize.c:
        rename: swap -> swap_variables
      mysys/my_compress.c:
        swap -> swap_variables
      mysys/my_handler.c:
        swap -> swap_variables
      sql/field.cc:
        Field::store_time refactored to use TIME_to_string function from time.cc
      sql/item.cc:
        New implementation of Item_param class:
        added support for character sets conversion.
      sql/item.h:
        Item_param:
        - 'state' member introduced instead of many boolean variables.
        - put ltime, int_value and real_value into union to save space.
        - remove unimplemented members
        - set_value renamed to set_str
      sql/item_timefunc.cc:
        Refactored to use functions from time.cc
      sql/lock.cc:
        rename: swap -> swap_variables
      sql/mysql_priv.h:
        - added declarations for TIME_to_ulonglong_*, TIME_to_string functions
        - const specifiers for make_date, make_time, make_datetime arguments
      sql/opt_range.cc:
        rename: swap -> swap_variables
      sql/protocol.cc:
        - added character set conversion support to binary protocol.
        - Protocol::convert changed to point at shared buffer in THD.
          This lets us use one convert buffer for binary and simple protocol.
          The same buffer is used for client->server conversions in prepared
          statements code.
        - string conversion code refactored to Protocol::store_string_aux function.
        - few more comments
      sql/protocol.h:
        - Protocol::convert now points at THD::convert_buffer: we want to share one
          buffer between all protocol implementations.
      sql/sql_class.cc:
        - implementation of THD::convert_string using THD::convert_buffer
          (conversion of strings allocated in the system heap).
      sql/sql_class.h:
        - THD::convert_buffer is shared between THD and network Protocols and
          used for character set conversion of strings.
        - new function to convert String object from one charset to another using
          THD::convert_buffer
      sql/sql_insert.cc:
        A little fix in a comment.
      sql/sql_parse.cc:
        Shrink convert buffer in the end of each statement.
      sql/sql_prepare.cc:
          Many changes:
        - static specifier for set_param_* family of functions.
        - FIELD_TYPE -> MYSQL_TYPE
        - added set_param_binary as handler for BLOB types.
        - added character set support
        - added support for param typecode in mysql_stmt_get_longdata
          (mysql_stmt_send_long_data handler)
        - changes in Item_param deployed
        - few cleanups
      sql/sql_select.cc:
        rename: swap -> swap_variables
      sql/sql_string.cc:
        - String::append rewritten to support character set conversion for
        single-byte encodings.
        - added String::swap method to efficiently exchange two string objects.
      sql/sql_string.h:
        Declraration for String::swap().
      sql/time.cc:
        - function TIME_to_string to convert TIME to String in default MySQL format
        - family of functions TIME_to_ulonglong_*
      tests/client_test.c:
        Test for support for character set conversions in prepared statements
        (binary and text data).

      Fix for bug which caused temp_table.test fail on Darwin 7.3 · 0bf85cfd
      unknown authored
      The code in mysql_create_table() code assumes that if lower_case_names==2 then table alias 
      should contain unchanged table name, and this was not true for temporary tables which
      had 'tmp-table' constant as alias. Now we are using table name as alias for such tables.
      
      
      sql/sql_lex.cc:
        Removed tmp_table_alias constant which is no longer used.
      sql/sql_lex.h:
        Removed tmp_table_alias constant which is no longer used.
      sql/sql_yacc.yy:
        Let us use table name instead of 'tmp-table' as alias for table being created by 
        CREATE TEMPORARY TABLE statement. This fixes failing temp_table.test on Darwin 7.3 
        since mysql_create_table() code assumes that if lower_case_names==2 then table alias 
        should contain unchanged table name (and now this assumtion is true but it were false
        for temporary tables before...).
