Missed error code resulted in my_ok() at higher frame which failed on
assertion for m_status in state of error.
ER_DUP_ENTRY on partitioned table
Now as c1492f3d07 (MDEV-36115) restores m_last_part table->file
points to partition p0 while the error happens in p1, so error index
does not match ib_table in innobase_get_mysql_key_number_for_index().
This case is handled by separate code block in
innobase_get_mysql_key_number_for_index() which was wrong on using
secondary index for dict_index_is_auto_gen_clust() and it was not
covered by the tests.
in row_update_for_mysql
932ec586 (MDEV-23644) in TABLE::delete_row() added ha_delete_row() for
the case of HA_ERR_FOREIGN_DUPLICATE_KEY. The problem is
ha_update_row() called beforewards may change m_last_part which is
required for ha_delete_row() to delete from correct partition.
The fix reverts m_last_part in case ha_partition::update_row() fails.
MDEV-34171 denied removing indirect routines/tables after
recover_from_failed_open() for auto-create partition case. Now we are
going further and keep them for any failed table reopen.
MDEV-34171 did not handle correctly open_and_process_routine() after
that skip of sp_remove_not_own_routines(). Now it is fixed by
sroutine_to_open correct usage.

Heap tables are allocated blocks to store rows according to
my_default_record_cache (mapped to the server global variable
read_buffer_size).
This causes performance issues when the record length is big
(> 1000 bytes) and the my_default_record_cache is small.
Changed to instead split the default heap allocation to 1/16 of the
allowed space and not use my_default_record_cache anymore when creating
the heap. The allocation is also aligned to be just under a power of 2.
For some test that I have been running, which was using record length=633,
the speed of the query doubled thanks to this change.
Other things:
- Fixed calculation of max_records passed to hp_create() to take
into account padding between records.
- Updated calculation of memory needed by heap tables. Before we
did not take into account internal structures needed to access rows.
- Changed block sized for memory_table from 1 to 16384 to get less
fragmentation. This also avoids a problem where we need 1K
to manage index and row storage which was not counted for before.
- Moved heap memory usage to a separate test for 32 bit.
- Allocate all data blocks in heap in powers of 2. Change reported
memory usage for heap to reflect this.

Fix for v.10.5
This patch extends the timestamp from
2038-01-19 03:14:07.999999 to 2106-02-07 06:28:15.999999
for 64 bit hardware and OS where 'long' is 64 bits.
This is true for 64 bit Linux but not for Windows.
This is done by treating the 32 bit stored int as unsigned instead of
signed. This is safe as MariaDB has never accepted dates before the epoch
(1970).
The benefit of this approach that for normal timestamp the storage is
compatible with earlier version.
However for tables using system versioning we before stored a
timestamp with the year 2038 as the 'max timestamp', which is used to
detect current values. This patch stores the new 2106 year max value
as the max timestamp. This means that old tables using system
versioning needs to be updated with mariadb-upgrade when moving them
to 11.4. That will be done in a separate commit.
Delayed_insert has its own THD (initialized at mysql_insert()) and
hence its own LEX. Delayed_insert initalizes a very few parameters for
LEX and 'duplicates' is not in this list. Now we copy this missing
parameter from parser LEX (as well as sql_command).
When INSERT does auto-create for t1 all its handler instances are
closed by alter_close_table(). At this time down the stack
maria_close() clears share->state_history. Later when we unlock the
tables Aria transaction manager accesses old share instance (the one
before t1 was closed) and tries to reset its state_history.
The problem is maria_close() didn't remove table from transaction's
list (used_tables). The fix does _ma_remove_table_from_trnman() which
is triggered by HA_EXTRA_PREPARE_FOR_RENAME.
prep_alter_part_table upon re-partitioning by system time
memcmp() tries to compare beyond the last member of interval because
sizeof(Vers_part_info::interval) is 80. It is sizeof of variable,
sizeof of type is 76.
Now we compare interval_t struct C++ way.
The assertion was to make sure we don't do vers_set_hist_part() for
SELECT (or any non-DML). But actually we must do it if SELECT calls
some function that does DML. Patch moves the assertion to non-routines
only.
differently react to SQL_MODE => unusable SHOW CREATE
Use abort_on_warning dependent on strict mode over create new table
like it is done for copy data and inplace alter.
This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
For commands
(1) alter table t1 add partition (partition p2);
(2) alter table t1 add partition (partition px history);
It printed the same error message:
Wrong partitioning type, expected type: `SYSTEM_TIME`
For (1) it is not clear from the syntax that we are trying to add
HASH partition. For (2) it is not clear that the table partitioning is
different than SYSTEM_TIME. Now it prints what type we are trying to
add to what type of partitioning.
Fixed warning unused function rename_field_in_list() for compilation
without partitioning.
* clarify the help text for --system-versioning-insert-history
