The problem was that opt_sum_query() was, as part of MIN/MAX optimization,
doing read operations on constant tables that where already closed
Fixed by ensuring we don't try to read from tables that are closed.

Per b9f3f06857ac, mysql_system_tables_data.sql creates
a mysql_native_password with a salted hash of "invalid" so that `set password`
will detect a native password can be applied:.
SHOW CREATE USER; diligently uses this value in its output
generating the SQL:
MariaDB [(none)]> show create user;
+---------------------------------------------------------------------------------------------------+
| CREATE USER for dan@localhost |
+---------------------------------------------------------------------------------------------------+
| CREATE USER `dan`@`localhost` IDENTIFIED VIA mysql_native_password USING 'invalid' OR unix_socket |
+---------------------------------------------------------------------------------------------------+
Attempting to execute this before this patch results in:
MariaDB [(none)]> CREATE USER `dan2`@`localhost` IDENTIFIED VIA mysql_native_password USING 'invalid' OR unix_socket;
ERROR 1372 (HY000): Password hash should be a 41-digit hexadecimal number
As such, deep the implementation of mysql_native_password we make "invalid" valid (pun intended)
such that the above create user will succeed. We do this by storing
"*THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE" (credit: Oracle MySQL), that is of an INCORRECT
length for a scramble.
In native_password_authenticate we check the length of this cached value
and immediately fail if it is anything other than the scramble length.
native_password_get_salt is only called in the context of set_user_salt, so all setting of native
passwords to hashed content of 'invalid', quite literally create an invalid password.
So other forms of "invalid" are valid SQL in creating invalid passwords:
MariaDB [(none)]> set password = 'invalid';
Query OK, 0 rows affected (0.001 sec)
MariaDB [(none)]> alter user dan@localhost IDENTIFIED BY PASSWORD 'invalid';
Query OK, 0 rows affected (0.000 sec)
closes #1628

Invoking memcpy() on a NULL pointer is undefined behaviour
(even if the length is 0) and gives the compiler permission to
assume that the pointer is nonnull. Recent versions of GCC
(starting with version 8) are more aggressively optimizing away
checks for NULL pointers. This undefined behaviour would cause
a SIGSEGV in the test main.func_encrypt on an optimized debug build
on GCC 10.2.0.

Also, revert the work-around for the test that was attempted in
commit 85613a32477ef4b8fb9aefba5f61689028f3ff87.
This issue was caught by MemorySanitizer as well as on the
Microsoft Windows debug builds, thanks to /MD being used
starting with 10.4.
The code fix will also be applied to 10.2 because the regression
was introduced in commit afc9d00c66db946c8240fe1fa6b345a3a8b6fec1.

Patch removes dict_index_t::stats_latch. Table/index statistics now
protected with dict_sys->mutex. That way statistics computation can
happen in parallel in several threads and dict_sys->mutex will be locked
only for a short period of time.
This patch is a joint work with Marko Mäkelä
dict_index_t::lock: make mutable which allows to pass const pointer
when only lock is touched in an object
btr_height_get()
btr_get_size(): make index argument const for better type safety
btr_estimate_number_of_different_key_vals(): now returns computed values
instead of setting fields in dict_index_t directly
remove everything related to dict_index_t::stats_latch
dict_stats_index_set_n_diff(): now returns computed values instead

Let us introduce a dummy variable innodb_max_purge_lag_wait
for waiting that the InnoDB history list length is below
the user-specified limit. Specifically,
SET GLOBAL innodb_max_purge_lag_wait=0;
should wait for all history to be purged. This could be useful
when upgrading from an older version to MariaDB 10.3 or later,
to avoid hitting MDEV-15912.
Note: the history cannot be purged if there exist transactions
that may see old versions.

MY_MEMORY_ORDER_RELAXED) == X_LOCK_DECR
InnoDB frees the block lock during buffer pool shrinking when other
thread is yet to release the block lock. While shrinking the
buffer pool, InnoDB allows the page to be freed unless it is buffer
fixed. In some cases, InnoDB releases the latch after unfixing the
block.
Fix:
====
- InnoDB should unfix the block after releases the latch.
- Add more assertion to check buffer fix while accessing the page.
- Introduced block_hint structure to store buf_block_t pointer
and allow accessing the buf_block_t pointer only by passing a
functor. It returns original buf_block_t* pointer if it is valid
or nullptr if the pointer become stale.
- Replace buf_block_is_uncompressed() with
buf_pool_t::is_block_pointer()
This change is motivated by a change in mysql-5.7.32:

Problem:
1. The server terminates abnormally when phrase search doesn't
filter out doc_ids correctly. This problem has been fixed in bug
2. Wrong query result: It's a regression from the bug #22709692 fix.
This fix optimize full-text search query with limit clause.
when FTS expression involves only union operation, we fetch only
number of doc_ids specified with the limit clause.
Fulltext phrase search is not an union operation and we consider
phrase search with plugin parser a union operation.
In phrase search with limit clause, we fetch limited doc_ids for
each token and if any of the selected doc_id does not contain all
tokens in correct order then we do not include that row_id in the
result set.
Therefore phrase search gets fewer number of rows than the qualified
rows exist in the table.
Fix:
Added a condition that phrase search with plugin parser is not a
union operation.

In Full-text phrase search, we filter out row that do not contain

If we do not filter out doc_id that doesn't appear in all the

if any of the token has last doc_id equal to ith doc_id of the first
token doc_id list then filter out rest of the higher doc_ids.

MariaDB 10.2.2 inherited from MySQL 5.7 a perceived optimization
of ALTER TABLE, which skips the writing of redo log records.
In MDEV-16809 we introduced a parameter that allows the redo log to
be written, so that Mariabackup would not be impacted, but we kept
the MySQL 5.7 behaviour enabled by default (innodb_log_optimize_ddl=ON).
As noted in MDEV-19747 (Deprecate and ignore innodb_log_optimize_ddl,
implemented in MariaDB 10.5.1), omitting the redo log writes can
actually reduce performance, because we will have to wait for the data
pages to be written out. When the redo log file is configured to be
large enough, it actually can be much faster to write the redo log and
avoid the extra page flushing.
When the redo log is omitted (innodb_log_optimize_ddl=ON), also
Mariabackup may have to perform a lot of extra work, to re-copy the
entire data file if it is possible that any log was omitted during
the backup.
Starting with MariaDB 10.5.1, the parameter innodb_log_optimize_ddl
is deprecated and ignored. We hereby deprecate (but will not ignore)
the parameter in earlier versions as well.

There are 2 issues here:
Issue #1: memory allocation.
An IO_CACHE that uses encryption uses a larger buffer (it needs space for the encrypted data,
decrypted data, IO_CACHE_CRYPT struct to describe encryption parameters etc).
Issue #2: IO_CACHE::seek_not_done
When IO_CACHE objects are cloned, they still share the file descriptor.
This means, operation on one IO_CACHE may change the file read position
which will confuse other IO_CACHEs using it.
The fix of these issues would be:
Allocate the buffer to also include the extra size needed for encryption.
Perform seek again after one IO_CACHE reads the file.

The characters parsed are always ascii characters, hence one byte. This
means that the code did not have "incorrect" logic because the boolean
condition, if true, would also evaluate to the value of 1.
The condition however is semantically wrong, assuming a length is equal
to the condition outcome. Change paranthesis to make it also read
according to the intent.
