they are ignored to a new test suite "innodb_plugin".
Remove a hack in mtr that was deployed to run the builtin InnoDB tests against
the InnoDB Plugin. Also detect if a test is an 'innodb plugin test' and if so
then transparently replace the builtin InnoDB with the InnoDB Plugin.

message:
Bug #49838: DROP INDEX and ADD UNIQUE INDEX for same index may corrupt
definition at engine
If a single ALTER TABLE contains both DROP INDEX and ADD INDEX using
the same index name (a.k.a. index modification) we need to disable
in-place alter table because we can't ask the storage engine to have
two copies of the index with the same name even temporarily (if we
first do the ADD INDEX and then DROP INDEX) and we can't modify
indexes that are needed by e.g. foreign keys if we first do
DROP INDEX and then ADD INDEX.
Fixed the problem by disabling in-place ALTER TABLE for these cases.

dict_table_check_for_dup_indexes(): Add the flag tmp_ok. If !tmp_ok,
check that no index name starts with TEMP_INDEX_PREFIX.
ha_innobase::add_index(), ha_innobase::prepare_drop_index(),
ha_innobase::final_drop_index(): Call dict_table_check_for_dup_indexes().
The problem is that we can not use make_cond_for_table().
This function relies on used_tables() condition
which is not set properly for subqueries.
As result subquery is not filtered out.
The fix is to use remove_eq_conds() function instead
of make_cond_for_table() func. 'remove_eq_conds()'
algorithm relies on const_item() value and it allows
to handle subqueries in right way.
Procedure, while DECIMAL works
Selecting of the CONCAT(...<SP variable>...) result into
a user variable may return wrong data.
Item_func_concat::val_str contains a number of memory
allocation-saving tricks. One of them concatenates
strings inplace inserting the value of one string
at the beginning of the other string. However,
this trick didn't care about strings those points
to the same data buffer: this is possible when
a CONCAT() parameter is a stored procedure variable -
Item_sp_variable::val_str() uses the intermediate
Item_sp_variable::str_value field, where it may
store a reference to an external buffer.
The Item_func_concat::val_str function has been
modified to take into account val_str functions
(such as Item_sp_variable::val_str) that return
a pointer to an internal Item member variable
that may reference to a buffer provided.
on index
'my_decimal' class has two members which can be used to access the
value. The member variable buf (inherited from parent class decimal_t)
is set to member variable buffer so that both are pointing to same value.
Item_copy_decimal::copy() uses memcpy to clone 'my_decimal'. The member
buffer is declared as an array and memcpy results in copying the values
of the array, but the inherited member buf, which should be pointing at
the begining of the array 'buffer' starts pointing to the begining of
buffer in original object (which is being cloned). Further updates on
'my_decimal' updates only the inherited member 'buf' but leaves
buffer unchanged.
Later when the new object (which now holds a inconsistent value) is cloned
again using proper cloning function 'my_decimal2decimal' the buf pointer
is fixed resulting in loss of the current value.
Using my_decimal2decimal instead of memcpy in Item_copy_decimal::copy()
fixed this problem.
data and index files
It was possible if DATA/INDEX DIRECTORY is pointing to
symlinked MySQL data home directory.
Do not allow to drop data/index files implicitly symlinked
to data home directory. For such tables remove symlink only.
