hangs on Linux

If REPAIR TABLE ... USE_FRM is issued for table that is located in different
than default database server crash could happen.

In reopen_name_locked_table take database name from table_list (user specified
or default database) instead of from thd (default database).

Affects 4.1 only.

This is addition to fix for bug21617. Valgrind reports an error when
opening merge table that has underlying tables with less indexes than
in a merge table itself.

Copy at most min(file->keys, table->key_parts) elements from rec_per_key array.
This fixes problems when merge table and subtables have different number of keys.

Though this is not storage engine specific problem, I was able to
repeat this problem with BDB and NDB engines only. That was the
reason to add a test case into ndb_update.test. As a result
different bad things could happen.

BDB has removed duplicate rows which is not expected.
NDB returns an error.

For multi table update notify storage engine about UPDATE IGNORE
as it is done in single table UPDATE.

create_tmp_table()".

The fix for bug 21787 "COUNT(*) + ORDER BY + LIMIT returns wrong
result" introduced valgrind warnings which occured during execution
of information_schema.test and sp-prelocking.test in version 5.0.
There were no user visible effects.

The latter fix made create_tmp_table() dependant on
THD::lex::current_select value. Valgrind warnings occured when this
function was executed and THD::lex::current_select member pointed
to uninitialized SELECT_LEX instance.

This fix tries to remove this dependancy by moving some logic
outside of create_tmp_table() function.


sql/sql_select.cc:
  create_tmp_table():
    Moved code which is responsible for determining if optimization
    which pushes down LIMIT clause to temporary table creation is
    applicable out of this function.
    Such move made this function independant of THD::lex::current_select
    value and removed valgrind warnings which occured in cases when this
    member pointed to uninitialized SELECT_LEX object (particularly these
    warnings occured in sp-prelocking.test and information_schema.test
    in 5.0). This seems like a better solution than trying to force this
    pointer always to point to relevant select because:
    - In some cases when we use create_tmp_table() there are no relevant
      SELECT_LEX object (we use it just to create temporary table/object).
    - There is only one place in code where we call this funciton and
      where this optimization can be enabled. And in this place we
      already have some logic which tries to determine if it is applicable.
