This was broken since commit 193b5ed5

The function was only called by innobase_drop_tablespace(),
which was removed in commit 494e4b99
and added in commit 2e814d47.

The issue here is for degenerate joins we should execute the window
function but it is not getting executed in all the cases.

To get the window function values window function needs to be executed
always. This currently does not happen in few cases
where the join would return 0 or 1 row like
  1) IMPOSSIBLE WHERE
  2) MIN/MAX optimization
  3) EMPTY CONST TABLE

The fix is to make sure that window functions get executed
and the temporary table is setup for the execution of window functions

innodb.cmake: restrict -fno-builtin-memcmp for GCC versions older that 4.6
where optimization issue was solved.

Add proper wait condition when provider options are restored.

MDEV-21189 : Dropping partition with 'wsrep_OSU_method=RSU' and 'SESSION sql_log_bin = 0' cases the galera node to hang

Test cleanup. Best practice for using RSU, is to isolate the node
up-front, so this test did not reflect real world scenario

- post-push to fix the compilation issue

- Moved the recv_sys->heap memory condition inside recv_parse_log_recs().
So that, InnoDB can mark the status as STORE_NO earlier.

- InnoDB uses one third of buffer pool chunk size for reading the redo
log records. In that case, we can avoid the scenario where buffer ran
out of memory issue during recovery.

It's not safe to chenge the THD::thread_id.
So send the thread_id as an argument to the mysql_audit_external_lock.

in 10.1+ one should use

MY_CHECK_AND_SET_COMPILER_FLAG("-Wno-address-of-packed-member")

and it's already done in storage/tokudb/PerconaFT/CMakeLists.txt

A debug assertion that was added in
commit ed0793e0
turns out to be too strict. In the test innodb_gis.rtree_compress,4k
the function is sometimes being invoked by purge for a
spatial index root page that is not a leaf page (PAGE_LEVEL is 1).

If we manually poison memory region, ASAN requires that we manually unpoison
it too. We didn't do it and munmap() didn't do it too. That was the issue.

os_mem_free_large(): unpoison memory region. Just in case.

Item_ref::val_(datetime|time)_packed() erroneously called
(*ref)->val_(datetime|time)_packed().

- Fixing to call (*ref)->val_(datetime|time)_packed_result().
- Backporting Item::val_(datetime|time)_packed_result() from 10.3.
- Fixing Item_field::get_date_result() to handle null_value in the same
  way how Item_field::get_date() does.

do not fallback to malloc(), always return properly aligned buffer

One may not call memcpy(dst, src=NULL, size), even if size==0.

Remove Query_tables_list::lock_tables_state - it is not used and it causes
errors like this:

sql_lex.h:1675:7: runtime error: load of value 2779096485, which is not a
valid value for type 'enum_lock_tables_state'

Fix wrong typecast

Problem was that wsrep_on was OFF.

Problem was that wsrep_on was OFF.

This is 10.4 version.

Fixed the condition for waking up/creating another thread.

If there is some work to do (if the request queue is not empty),
a thread should be woken or created.

The condition was incorrect since 18c9b345

We cannot have -Werror for third-party submodules because
whenever they break the build we cannot fix it as needed.

The query requires 2 temporary tables for execution, the window function
is always attached to the last temporary table, but in this case the
result field of the window function points to the first temporary table
rather than the last one.
Fixed this by not changing window function items with temporary table
items of the first temporary table.

The function was only used by trx_undo_page_init_log()
(writing the MLOG_UNDO_INIT record), which was removed in
commit ccb35502.

This commit updates the wsrep-lib. The changes are a cleanup in
client_state TOI processing and stub methods for future extensions.
