In MySQL 5.7, a follow-up to WL#6671 removed the unused
fields ha_innobase::lock and INNOBASE_SHARE::lock, but
MariaDB did not remove them, even though a counterpart of
WL#6671 itself was implemented as MDEV-7660 in
commit d665e79c5b.
INNOBASE_SHARE was removed in MDEV-16557. Thus, all that
needs to be removed is the unused member ha_innobase::lock
and related code.
Thanks to Monty (and Valgrind) for noticing that
ha_innobase::lock was uninitialized.
The problem occurs in 10.2 and earlier releases of MariaDB Server because the
Partition Engine was not pushing the engine conditions to the underlying
storage engine of each partition. This caused Spider to return the first 5
rows in the table with the data provided by the customer. 2 of the 5 rows
did not qualify the WHERE clause, so they were removed from the result set by
the server.
To fix the problem, I have back-ported support for engine condition pushdown
in the Partition Engine from MariaDB Server 10.3.

When counter increment is not within the expected range, print the number
instead of just FAIL.
This doesnt solve the bug but will help with the diagnostics.

Because innodb_file_per_table can be enabled at runtime after it
was disabled at startup, it is better to always register the same
innobase_hton->tablefile_extensions. Besides,
innodb_file_per_table=OFF does not prevent loading tables that may
have been created earlier with the .ibd file extension.
don't create static objects that destroy mutexes from destructors,
and don't destroy mutexes from .so destructor (on-unload) function.
if it happens after exit(), P_S will be long gone by that time
this fixes tokudb tests crashing on quantal-amd64
Disable "Invalid (old?) table or database name" warning when
converting table names in InnoDB's get_foreign_key_info().
Because a name can be a temporary table name during the ALTER TABLE,
and some other thread can do SHOW CREATE TABLE for the other table
in the FK relationships _anytime_.

This regression was introduced in MDEV-16515.
We would fail to drop a temporary table on client disconnect,
because trx_is_interrupted() would hold. To add insult to
injury, in MariaDB 10.1, InnoDB temporary tables are actually
persistent, so the garbage temporary tables will never be dropped.
row_drop_table_for_mysql(): If several iterations of
buf_LRU_drop_page_hash_for_tablespace() are needed,
do not interrupt dropping a temporary table even after
the transaction was marked as killed.
Server shutdown will still terminate the loop, and also DROP TABLE
of persistent tables will keep checking if the execution was aborted.

Problem was that a parallel open of a table, overwrote info->state that
was in used by repair.
Fixed by changing _ma_tmp_disable_logging_for_table() to use
a new state buffer state.no_logging to store the temporary state.
Other things:
- Use original number of rows when retrying repair to get rid of a
potential warning "Number of rows changed from X to Y"
- Changed maria_commit() to make it easier to merge with 10.4
- If table is not locked (like with show commands), use the global
number of rows as the local number may not be up to date.
(Minor not critical fix)
- Added some missing DBUG_RETURN
Currently RocksDB engine doesn't update AUTO_INCREMENT in the UPDATE statement.
For example,
CREATE TABLE t1 (pk INT AUTO_INCREMENT, a INT, PRIMARY KEY(pk)) ENGINE=RocksDB;
INSERT INTO t1 (a) VALUES (1);
UPDATE t1 SET pk = 3; ==> AUTO_INCREMENT should be updated to 4.
Without this fix, it hits the Assertion `dd_val >= last_val' failed in
myrocks::ha_rocksdb::load_auto_incr_value_from_index.

An INSERT into a temporary table would fail to set the
index page as modified. If there were no other write operations
(such as UPDATE or DELETE) to the page, and the page was evicted,
we would read back the old contents of the page, causing
corruption or loss of data.
page_cur_insert_rec_write_log(): Call mtr_t::set_modified()
for temporary tables. Normally this is part of the mlog_open()
call, but the mlog_open() call was only present in debug builds.
This regression was caused by
commit 48192f963a
which was preparation for MDEV-11369 and supposed to affect
debug builds only.
Thanks to Thirunarayanan Balathandayuthapani for debugging.
When a table is renamed to an internal #sql2 or #sql-ib name during
a table-rebuilding DDL operation such as OPTIMIZE TABLE or ALTER TABLE,
and shortly after that a purge operation in an index on virtual columns
is attempted, the operation could fail, but purge would fail to release
the table reference.
innodb_acquire_mdl(): Release the reference if the table name is not
valid for acquiring a meta-data lock (MDL).
innodb_find_table_for_vc(): Add a debug assertion if the table name
is not valid. This code path is for DML execution. The table
should have a valid name for executing DML, and furthermore a MDL
will prevent the table from being renamed.
row_vers_build_clust_v_col(): Add a debug assertion that both indexes
must belong to the same table.
