f9c3cb5f2e Fix for bug#4302 "ambiguos order by when renamed column is identical to another in result"
When in find_item_in_list() we are looking for item we should take into account unaliased 
names of the fields but only if item with such aliased name is not found.
Also we should ignore aliases when looking for fully specified field.


mysql-test/r/order_by.result:
  Fixed wrong (non-standard) test results
  Added test case for bug #4302
  Added tests for other ambiguos and potentially ambigous cases in order by clause
mysql-test/t/order_by.test:
  Fixed wrong (non-standard) test results
  Added test case for bug #4302
  Added tests for other ambiguos and potentially ambigous cases in order by clause
sql/sql_select.cc:
  We should ignore only not_found_item errors when searching for item in find_order_in_list() 
  to be able to catch ambiguities.

7e5247aade fixed Bug #4358 Problem with HAVING clause that uses alias
from the select list and TEXT field 

make setup_copy_fields to insert Item_copy_string for blobs in 
the beginning of the copy_funcs (push_back instead of push_front)

the thing is that Item_copy_string::copy for function can call 
Item_copy_string::val_int for blob via Item_ref.
But if Item_copy_string::copy for blob isn't called before, 
it's value will be wrong.

So all the Item_copy_string::copy for blobs should be called before 
Item_copy_string::copy for functions.

68d7b26698 Fix for bug #4508 "CONVERT_TZ() function with new time zone as param crashes server".
Instead of trying to open time zone tables during calculation of CONVERT_TZ() function
or setting of @@time_zone variable we should open and lock them with the rest of 
statement's table (so we should add them to global table list) and after that use such 
pre-opened tables for loading info about time zones.


mysql-test/r/timezone2.result:
  Added test for bug #4508
mysql-test/t/timezone2.test:
  Added test for bug #4508
scripts/mysql_create_system_tables.sh:
  Added one more test time zone to time zone tables which is needed for test for bug #4508.
sql/item_create.cc:
  CONVERT_TZ() now is treated as special function.
sql/item_create.h:
  CONVERT_TZ() now is treated as special function.
sql/item_timefunc.cc:
  Item_func_convert_tz now uses list of pre-opened time zone tables instead of trying to
  open them ad-hoc. Also it avoid calling of current_thd.
sql/item_timefunc.h:
  Added comment describing special nature of CONVERT_TZ() function.
  Optimization: Added own fix_fields() method and tz_tables member for caching pointer
  to list of open time zone tables to Item_func_convert_tz class.
sql/lex.h:
  CONVERT_TZ() now is treated as special function.
sql/mysql_priv.h:
  Removed function which is no longer used.
sql/set_var.cc:
  Now my_tz_find() accepts list of pre-opened time zone tables as last argument 
  and no longer needs pointer to current THD.
sql/set_var.h:
  Exported sys_time_zone, which is now used in sql_yacc.yy for quick finding out if we are
  setting @@time_zone variable.
sql/sql_base.cc:
  Moved propagation of pointers to open tables from global list to local select lists to
  open_and_lock_tables(), also added implicit usage of time zone tables as condition for
  such propagation.
sql/sql_lex.cc:
  Added fake_time_zone_tables_list which is used to indicate that time zone tables are
  implicitly used in statement.
  st_select_lex_unit::create_total_list(): if time zone tables are implicitly used in
  statement add them to global tables list.
sql/sql_lex.h:
  Added LEX::time_zone_tables_used member which is used to indicate that time zone tables 
  are implicitly used in this statement (by pointing to fake_time_zone_table_list) and 
  for holding pointer to those tables after they've been opened.
sql/sql_parse.cc:
  We should also create global table list if statement uses time zone tables implicitly.
  Added initialization of LEX::time_zone_tables_used to mysql_query_init().
sql/sql_prepare.cc:
  We should also create global table list if statement uses time zone tables implicitly.
sql/sql_select.cc:
  Removed functions which are no longer used.
sql/sql_yacc.yy:
  CONVERT_TZ() and @@time_zone variable are handled in special way since they implicitly 
  use time zone tables.
sql/tztime.cc:
  Fix for bug #4508 "CONVERT_TZ() function with new time zone as param crashes server".
  If statement uses CONVERT_TZ() function or @@time_zone variable is set then it implicitly
  uses time zone tables. We need to open and lock such tables with all other tables of 
  such statement.
  
  All code responsible for opening table was removed from tz_load_from_db() and function was 
  renamed to tz_load_from_open_tables() (which uses list of pre-opened tables).
  We also have new functions for construction and initialization of table list of time
  zone tables.
  my_tz_find() now always require list of pre-opened time zone tables and no longer needs
  current THD. So we have to pre-open them in my_tz_init().
  Also now we try to open time zone tables only if they were found during startup.
sql/tztime.h:
  New function for construction of table list of time zone tables my_tz_get_table_list().
  Now my_tz_find() requires list of pre-pened time zone tables instead of current thread.

eaf34dd8e3 Port of cursors to be pushed into 5.0 tree:
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.


include/mysql.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new statement attribute STMT_ATTR_CURSOR_TYPE
  - MYSQL_STMT::flags to store statement cursor type
  - MYSQL_STMT::server_status to store server status (i. e. if the server
  was able to open a cursor for this query).
include/mysql_com.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new COMmand, COM_FETCH, to fetch K rows from read-only cursor.
    By design should support scrollable cursors as well.
  - a few new server statuses:
    SERVER_STATUS_CURSOR_EXISTS is sent by server in reply to COM_EXECUTE,
    when cursor was successfully opened for this query
    SERVER_STATUS_LAST_ROW_SENT is sent along with the last row to prevent one
    more round trip just for finding out that all rows were fetched from 
    this cursor (this is server mem savier also).
  - and finally, all possible values of STMT_ATTR_CURSOR_TYPE, 
    while now we support only CURSORT_TYPE_NO_CURSOR and 
    CURSOR_TYPE_READ_ONLY
libmysql/libmysql.c:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - simple additions to mysql_stmt_fetch implementation to read data 
    from an opened cursor: we can read up to iteration count rows per
    one request; read rows are buffered in the same way as rows of
    mysql_stmt_store_result.
  - now send stmt->flags to server to let him now if we wish to have 
    a cursor for this statement.
  - support for setting/getting statement cursor type.
libmysqld/examples/Makefile.am:
  Testing cursors was originally implemented in C++. Now when these tests
  go into client_test, it's time to convert it to C++ as well.
libmysqld/lib_sql.cc:
  - cleanup: send_fields flags are now named.
sql/ha_innodb.cc:
  - cleanup: send_fields flags are now named.
sql/mysql_priv.h:
  - cursors support: declaration for server-side handler of COM_FETCH
sql/protocol.cc:
  - cleanup: send_fields flags are now named.
  - we can't anymore assert that field_types[field_pos] is sensible:
    if we have COM_EXCUTE(stmt1), COM_EXECUTE(stmt2), COM_FETCH(stmt1)
    field_types[field_pos] will point to fields of stmt2.
sql/protocol.h:
  - cleanup: send_fields flag_s_ are now named.
sql/protocol_cursor.cc:
  - cleanup: send_fields flags are now named.
sql/repl_failsafe.cc:
  - cleanup: send_fields flags are now named.
sql/slave.cc:
  - cleanup: send_fields flags are now named.
sql/sp.cc:
  - cleanup: send_fields flags are now named.
sql/sp_head.cc:
  - cleanup: send_fields flags are now named.
sql/sql_acl.cc:
  - cleanup: send_fields flags are now named.
sql/sql_class.cc:
  - cleanup: send_fields flags are now named.
sql/sql_class.h:
  - cleanup: send_fields flags are now named.
sql/sql_error.cc:
  - cleanup: send_fields flags are now named.
sql/sql_handler.cc:
  - cleanup: send_fields flags are now named.
sql/sql_help.cc:
  - cleanup: send_fields flags are now named.
sql/sql_parse.cc:
  Server side support for cursors:
  - handle COM_FETCH
  - enforce assumption that whenever we free thd->free_list, 
    we reset it to zero. This way it's much easier to handle free_list
    in prepared statements implementation.
sql/sql_prepare.cc:
  Server side support for cursors:
  - implementation of mysql_stmt_fetch (fetch some rows from open cursor).
  - management of cursors memory is quite tricky now.
  - execute_stmt can't be reused anymore in mysql_stmt_execute and 
    mysql_sql_stmt_execute
sql/sql_repl.cc:
  - cleanup: send_fields flags are now named.
sql/sql_select.cc:
  Server side support for cursors:
  - implementation of Cursor::open, Cursor::fetch (buggy when it comes to
    non-equi joins), cursor cleanups.
  - -4 -3 -0 constants indicating return value of sub_select and end_send are
    to be renamed to something more readable:
    it turned out to be not so simple, so it should come with the other patch.
sql/sql_select.h:
  Server side support for cursors:
  - declaration of Cursor class.
  - JOIN::fetch_limit contains runtime value of rows fetched via cursor.
sql/sql_show.cc:
  - cleanup: send_fields flags are now named.
sql/sql_table.cc:
  - cleanup: send_fields flags are now named.
sql/sql_union.cc:
  - if there was a cursor, don't cleanup unit: we'll need it to fetch
    the rest of the rows.
tests/Makefile.am:
  Now client_test is in C++.
tests/client_test.cc:
  A few elementary tests for cursors.
BitKeeper/etc/ignore:
  Added libmysqld/examples/client_test.cc to the ignore list

d3e520ce7e Port of cursors to be pushed into 5.0 tree:
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.
