SELECT ... GROUP BY bit field failed with an assertion if the
bit length of that field was not divisible by 8.
sql/key.cc:
Fixed bug #32556.
Copying of "uneven" bits of a bit field was duplicated in the
key_copy() and in the Field_bit::get_key_image().
So, instead of copying of the rest of a bit field,
Field_bit::get_key_image() copied "uneven" bits to key image again,
and the lowest field byte was not copied to key at all.
Duplicated code has been removed from the key_copy function.

the argument if necessary and returns a proper value.

Index lookup does not always guarantee that we can
simply remove the relevant conditions from the WHERE
clause. Reasons can be e.g. conversion errors,
partial indexes etc.
The optimizer was removing these parts of the WHERE
condition without any further checking.
This leads to "false positives" when using indexes.
Fixed by checking the index reference conditions

Fixes the following bugs:
- Bug #29560: InnoDB >= 5.0.30 hangs on adaptive hash rw-lock 'waiting for an X-lock'
Fixed a race condition in the rw_lock where an os_event_reset()
can overwrite an earlier os_event_set() triggering an indefinite
wait.

sync0arr which was applied to 5.0 only. Therefore, it need not be

to 5.1 then this fix should be ported as well.

The problem is that DROP TABLE and other DDL statements failed to
automatically close handlers associated with tables that were marked
for reopen (FLUSH TABLES).
The current implementation fails to properly discard handlers of
dropped tables (that were marked for reopen) because it searches
on the open handler tables list and using the current alias of the
table being dropped. The problem is that it must not use the open
handler tables list to search because the table might have been
closed (marked for reopen) by a flush tables command and also it
must not use the current table alias at all since multiple different
aliases may be associated with a single table. This is specially
visible when a user has two open handlers (using alias) of a same
table and a flush tables command is issued before the table is
dropped (see test case). Scanning the handler table list is also
useless for dropping handlers associated with temporary tables,
because temporary tables are not kept in the THD::handler_tables
list.
The solution is to simple scan the handlers hash table searching
for, and deleting all handlers with matching table names if the
reopen flag is not passed to the flush function, indicating that
the handlers should be deleted. All matching handlers are deleted
even if the associated the table is not open.

This bug is actually two. The first one manifests itself on an EXPLAIN
SELECT query with nested subqueries that employs the filesort algorithm.
The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve
some temporary structures for explain. As a side-effect of this values of
nested subqueries weren't cached and subqueries were re-evaluated many
times. Each time buffer for filesort was allocated but wasn't freed because
freeing occurs at the end of topmost SELECT. Thus all available memory was
eaten up step by step and OOM event occur.
The second bug manifests itself on SELECT queries with conditions where
a subquery result is compared with a key field and the subquery itself also
has such condition. When a long chain of such nested subqueries is present
the stack overrun occur. This happens because at some point the range optimizer
temporary puts the PARAM structure on the stack. Its size if about 8K and
the stack is exhausted very fast.
Now the subselect_single_select_engine::exec function allows subquery result
caching when the UNCACHEABLE_EXPLAIN flag is set.
Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun
function for stack checking purposes to prevent server crash.

until the stack is consumed.
If my_net_init fails (for example: because of OOM) the temporary vio object
might have been attached to the thd object already. This will cause a double
free on the vio object when the thd object is deleted later on and the server
will crash.

Refactored reset_lex method to return a error state code instead of void.
Initialize the mem-root with init_sql_alloc to get a basic error handler for
memory allocation problems. This alone won't prevent the server from crashing,
NULL pointers have to be accounted for as well.
sql/sp_head.h:
Use the throw() clause in operator new, to indicate to the compiler that
memory allocation can fail and return NULL, so that the compiler should
generate code to check for NULL before invoking C++ constructors, to be
crash safe.
sql/sql_base.cc:
Use init_sql_alloc to get basic out-of-memory error handling.
sql/sql_lex.h:
Use the throw() clause in operator new, to indicate to the compiler that
memory allocation can fail and return NULL, so that the compiler should
generate code to check for NULL before invoking C++ constructors, to be
crash safe.
sql/sql_prepare.cc:
Use init_sql_alloc to get basic out-of-memory error handling.
sql/sql_yacc.yy:
Check for memory allocation failures where it matters.

corrupts a MERGE table
Post-pushbuild fix for a Valgrind warning.
mysql-test/r/merge.result:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Fixed test result.
mysql-test/t/merge.test:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Removed unnecessary statements from test.
sql/sql_trigger.cc:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Fixed usage of db and table_name for
close_data_files_and_morph_locks().
Comparison of a BIGINT NOT NULL column with a constant arithmetic
expression that evaluates to NULL caused error 1048: "Column '...'
cannot be null".
Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in a
NOT NULL field caused query errors.
sql/item_cmpfunc.cc:
Fixed bug #32335.
1. Made convert_constant_item() check if the constant expression is NULL
before attempting to store it in a field. Attempts to store NULL in
a NOT NULL field caused query errors.
2. Also minor bug has been fixed: the thd->count_cuted_fields value
was not restored in case of successful conversion.
mysql-test/t/select.test:
Added test case for bug #32335.
mysql-test/r/select.result:
Added test case for bug #32335.
post-merge fixes: some things work differently in 5.1
mysql-test/r/type_newdecimal.result:
post-merge fix: 5.1 throws different warning here
sql/sql_select.cc:
post-merge fix: signature has changed in 5.1
