- This issue caused by commit a032f14b342c782b82dfcd9235805bee446e6fe8(MDEV-33559).
In MDEV-33559, matched_rec::block was changed to pointer
and assinged with the help of buf_block_alloc(). But patch
fails to check for the block can be nullptr in
rtr_check_discard_page().
rtr_cur_search_with_match(): Acquire rtr_match_mutex before
creating shadow block for the matched records
rtr_pcur_move_to_next(): Copy the shadow block to page cursor
block under rtr_match_mutex
mysql_prepare_create_table: Extract a Key initialization part that
relates to length calculation and long unique index designation.
append_system_key_parts call also moves there.
Move this initialization before the duplicate elimination.
Extract WITHOUT OVERPLAPS check into a separate function. It had to be moved
earlier in the code to preserve the order of the error checks, as in the tests.
- InnoDB fails to set the index information or index number
for the spatial index error HA_ERR_NULL_IN_SPATIAL.
row_build_spatial_index_key(): Initialize the tmp_mbr array completely.
check_if_supported_inplace_alter(): Fix the spelling mistake of alter
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
There are 3 diff in result:
1) NULL value from SELECT
Due to incorrect truncating of the hex value, incorrect value is
written instead of original value to the view frm. This results in reading
incorrect value from frm, so eventual result is NULL.
2) 'Name_exp1' in column name (in gis.test)
This was because the identifier in SELECT is longer than 64 characters,
so 'Name_exp1' alias is also written to the view frm.
3)diff in explain extended
This was because the query plan for view protocol doesn't
contain database name. As a fix, disable view protocol for that particular
query.
On Windows systems, occurrences of ERROR_SHARING_VIOLATION due to
conflicting share modes between processes accessing the same file can
result in CreateFile failures.
mysys' my_open() already incorporates a workaround by implementing
wait/retry logic on Windows.
But this does not help if files are opened using shell redirection like
mysqltest traditionally did it, i.e via
--echo exec "some text" > output_file
In such cases, it is cmd.exe, that opens the output_file, and it
won't do any sharing-violation retries.
This commit addresses the issue by introducing a new built-in command,
'write_line', in mysqltest. This new command serves as a brief alternative
to 'write_file', with a single line output, that also resolves variables
like "exec" would.
Internally, this command will use my_open(), and therefore retry-on-error
logic.
Hopefully this will eliminate the very sporadic "can't open file because
it is used by another process" error on CI.
In any test that uses wait_all_purged.inc, ensure that InnoDB tables
will be created without persistent statistics.
This is a follow-up to commit cd04673a17
after a similar failure was observed in the innodb_zip.blob test.
