The thd->lex->part_info should be kept intact during PS
execution. Or the second execution gets that modified part_info.
Let's modify ths->work_part_info instead.
Item_xml_str_func::fix_fields() used a local "String tmp" as a buffer
for args[1]->val_str(). "tmp" was freed at the end of fix_fields(),
while Items created during my_xpath_parse() still pointed to its fragments.
Adding a new member Item_xml_str_func::m_xpath_query and store the result
of args[1]->val_str() into it.

did not have it).

- Fix MDEV-9844, MDEV-10179, MDEV-14214
This is done by removing the tbl table type THREAD option
that causes a multiple of sporadic bugs.
This may be temporary depending on whether a real fix is found.

"tokudb_alter_table.drop_add_pk_part_104 leaves a temporary file behind"
Fixed by copying 3 lines from 10.1 to 10.0 that cleaned up the temporary
file for partitioning tables.
May also fix: MDEV-14970 "MariaDB crashed with signal 11 and Aria table"
I am not able to reproduce a crash, however there was no protection in
print_keydup_error() if the storage engine reported the wrong key number.
This patch adds such a protection and should stop any further crashes
in this case.
Other things:
- Added extra protection in Aria to not set errkey to more than number of
keys. (Don't think this is cause of this crash, but better safe than
sorry)
- Extend test_if_equal_repl_errors() to handle different cases of
ER_DUP_ENTRY. This is just mainly precaution for the future.
mem_heap_free_heap_top(): Remove UNIV_MEM_ASSERT_W() and unpoison
the memory region first, because part of it may have been poisoned
by an earlier mem_heap_free_top() call.
Poison the address range at the end.
mem_heap_block_free(): Poison the address range at the end.
UNIV_MEM_ASSERT_AND_ALLOC(): Replace with UNIV_MEM_ALLOC().
We want to keep the address ranges poisoned (unaccessible) as
long as possible.
UNIV_MEM_ASSERT_AND_FREE(): Replace with UNIV_MEM_FREE().
MDEV-14957: JOIN::prepare gets unusable "conds" as argument
Do not touch merged derived (it is irreversible)
Fix first argument of in_optimizer for calls possible before fix_fields()
escape all charecters less or equal 0x1F (control symbols)
(shorter sequence are not used to make code simple, long encoding is always legal according to the rfc4627)
Problem:-
If we create table using myisam/aria then this crashes the server.
CREATE TABLE t1(a bit(1), b int auto_increment , index(a,b));
insert into t1 values(1,1);
Or this query
CREATE TABLE t1 (b BIT(1), pk INTEGER AUTO_INCREMENT PRIMARY KEY);
ALTER TABLE t1 ADD INDEX(b,pk);
INSERT INTO t1 VALUES (1,b'1');
ALTER TABLE t1 DROP PRIMARY KEY;
Reason:-
The reason for this is
1st- find_ref_key() finds what key an auto_increment field belongs to by
comparing key_part->offset and field->ptr. But BIT fields might have
zero length in the record, so a key might have many key parts with the
same offset. That is, comparing offsets cannot uniquely identify the
correct key part.
2nd- Since next_number_key_offset is zero it myisam/aria will think that
auto_increment is in first part of key.
3nd- myisam/aria will call retrieve_auto_key which will see first key_part
field as a bit field and call assert(0)
Solution:-
Many key parts might have the same offset, but BIT fields do not
support auto_increment. So, we can skip all key parts over BIT fields,
and then comparing offsets will be unambiguous.
