Consider a query of the form:

  select ... from (select item2 as COL1) as T where COL1=123

Condition pushdown into derived table will try to push "COL1=123" condition
down into table T.
The process of pushdown involves "substituting" the item, that is,
replacing Item_field("T.COL1") with its "producing item" item2.
In order to use item2, one needs to clone it (call Item::build_clone).

If the item is not cloneable (e.g. Item_func_sp is not), the pushdown
process will fail and nothing at all will be pushed.

Fixed by introducing transform_condition_or_part() which will try to apply
the transformation for as many parts of condition as possible. The parts of
condition that couldn't be transformed are dropped.

Add KEYWORDS table and SQL_FUNCTIONS table to INFORMATION_SCHEMA.
This commits needs some minor changes when propagated upwards
(e.g. func_array in item_create.cc has a termination element that
 doesn't exist in later versions of MariaDB)

os_file_set_size(): Trim the current size down to the file system
block size, to obey the constraints for unbuffered I/O.

Handle invalid GEOJSON-s in Geometry::create_from_json().

If the first token of the body of a stored procedure was 'WITH' then
the beginning of the body was determined incorrectly and that token was
missing in the string representing the body of the SP in mysql.proc. As a
resultnany call of such procedure failed as the string representing the
body could not be parsed.

The patch corrects the code of the functions get_tok_start() and
get_cpp_tok_start() of the class Lex_input_stream to make them take into
account look ahead tokens. The patch is needed only for 10.2 as this
problem has neen resolved in 10.3+.

Fixed typo in variable name that breaks SST in some scenatios.

Also fixed one small inaccuracy after MDEV-25978 which leads
to the use of an uninitialized variable when the --log-bin
option is specified without an argument.

wsrep_sst_common did not correctly set name for binlog index
file if custom binlog name was used and this name was
not added to script command line.

Added test case for both log_basename and log_binlog.

added %config directive to /etc/logrotate.d/mysql and put it to server
package. if file is edited by customer and defaults are changed - new
.rpmnew file with defaults will be created next to old one.

init_crypt_key(): On failure, set info->key_version to
ENCRYPTION_KEY_VERSION_INVALID.

log_crypt_101_read_block(): Refuse to attempt decryption if
info->key_version is ENCRYPTION_KEY_VERSION_INVALID.

This bug affected queries with views / derived_tables / CTEs whose
specifications were of the form
  (SELECT ... LIMIT <n>) ORDER BY ...
Units representing such specifications contains one SELECT_LEX structure
for (SELECT ... LIMIT <n>) and additionally SELECT_LEX structure for
fake_select_lex. This fact should have been taken into account in the
function mysql_derived_fill().

This patch has to be applied to 10.2 and 10.3 only.

Builds on travis-ci.org ceased on 2021-06-15.

- Make innodb_fts.misc_debug test case more stable.

In commit 1c35a3f6 a useless
computation that used the variable was removed.

Additional improvements aimed at improving operational
reliability of the SST scripts:

1) Script need to give rsync and stunnel a short time to
   terminate after "kill -9" before the first PID check
   using ps utility;
2) The temporary file used to create the binlog index could
   sometimes remain in the data directory if tar failed and
   then may be reused without being cleaned up (the next
   time when SST was run) - now it's fixed;
3) The temporary file used to build the binlog index is now
   created using mktemp and, if this variable is present in
   the configuration file, in tmpdir;
4) Checking the secret tag in SST via rsync is made faster
   and does not require creating a temporary file, which
   could remain in the data directory in case of failure;
5) Added "-F" option to grep to check the tag when using
   mariabackup/xtrabackup-v2 - to avoid possible collisions
   in case of special characters in the tag value (unlikely
   scenario, but the new check is more reliable).

This commit fixes a bug was originally discovered during the
galera_nbo_sst_slave mtr test for 10.6 branch. However it is
relevant for all versions and can lead to intermittent SST
crashes via rsync on very fast server restarts - when a new
SST process (for example, after starting a new server instance)
overlaps the old SST process started by the previous, already
terminated server. This overlap can result in the new rsync
being killed instead of the old rsync, or the pid file from
the new rsync being killed, which then lead to problems.

a new warning -Wunused-but-set-variable was introduced recently to clang

- During online alter conversion from compact to redundant,
virtual column field length already set during
innobase_get_computed_value(). Skip the char(n) check for
virtual column in row_merge_buf_add()

MDEV-25872 InnoDB: Assertion failure in row_merge_read_clustered_index upon ALTER on table with indexed virtual columns

- InnoDB fails to check DB_COMPUTE_VALUE_FAILED error in
row_merge_read_clustered_index() and wrongly asserts that
the buffer shouldn't be ran out of memory. Alter table
should give warning when the column value is being
truncated.

Problem:
=======
- InnoDB iterates the fil_system space list to encrypt the
tablespace in case of key rotation. But it is not
necessary for any encryption plugin which doesn't do
key version rotation.

Solution:
=========
- Introduce a new variable called srv_encrypt_rotate to
indicate whether encryption plugin does key rotation

fil_space_crypt_t::key_get_latest_version(): Enable the
srv_encrypt_rotate only once if current key version is
higher than innodb_encyrption_rotate_key_age

fil_crypt_must_default_encrypt(): Default encryption tables
should be added to default_encryp_tables list if
innodb_encyrption_rotate_key_age is zero and encryption
plugin doesn't do key version rotation

fil_space_create(): Add the newly created space to
default_encrypt_tables list if
fil_crypt_must_default_encrypt() returns true

Removed the nondeterministic select from
innodb-key-rotation-disable test. By default,
InnoDB adds the tablespace to the rotation list and
background crypt thread does encryption of tablespace.
So these select doesn't give reliable results.

- Rename the rotation list to default_encrypt_tables in
fil_system_t. Because rotation list naming could be
misleading when it comes to key version rotation

- Rename is_in_rotation_list to is_in_default_encrypt
in fil_space_t

- Rename keyrotate_next function to default_encrypt_next

fil_system_t::default_encrypt_next(): Find the next
suitable default encrypt table if beginning of
default_encrypt_tables list has been scheduled
to be deleted

As such the Oracle Copyright header isn't really applicable.

Fix malloc/delete mismatch. This causes a double free in the cleanup.

closes #1845

* read_command_buf is a pointer now, sizeof() no longer reflects its
  length, read_command_buflen is.
* my_safe_print_str() prints multiple screens of '\0' bytes after the
  query end and up to read_command_buflen. Use fprintf() instead.
* when setting connection->name to "-closed_connection-" update
  connection->name_len to match.

Not all environments have 'diff' installed. Most notably CentOS 8
does not have diff out-of-the-box. Thus users running 'cmake .' and
'make' would fail to build MariaDB, and they would think the error
was in ABI incompatibilities due to the error message emitted by CMake
when in reality simply 'diff' was missing.

This fixes it and makes the developer experience better by simply
skipping the diffing if 'diff' is not found.

Closes #1846

This was missed in commit 1d0f70c2.

* Make Item_in_optimizer::fix_fields inherit the with_window_func
  attribute of the subquery's left expression (the subquery itself
  cannot have window functions that are aggregated in this select)

* Make Item_cache_wrapper::Item_cache_wrapper() inherit
  with_window_func attribute of the item it is caching.

buf_read_ibuf_merge_pages(): If space->size is 0, invoke
fil_space_get_size() to determine the size of the tablespace
by reading the header page. Only after that proceed to delete
any entries that are beyond the end of the tablespace.
Otherwise, we could be deleting valid entries that actually
need to be applied.

This fixes a regression that had been introduced in
commit b80df9eb (MDEV-21069),
which aimed to avoid crashes during DROP TABLE of corrupted tables.

This partially reverts commit d7321893.

The *.jar files are not being built and all Debian builds are failing
as dh_install stops on missing files. To build them we would need to also
add new Java build dependencies.

In a stable release (10.2->10.5) we shouldn't add new files and certainly
not any new build dependencies, so reverting commit.

Also, the files are located in a different path, and already included
in the mariadb-test-data package:

  /usr/share/mysql/mysql-test/plugin/connect/connect/std_data/JavaWrappers.jar
  /usr/share/mysql/mysql-test/plugin/connect/connect/std_data/JdbcMariaDB.jar
  /usr/share/mysql/mysql-test/plugin/connect/connect/std_data/Mongo2.jar
  /usr/share/mysql/mysql-test/plugin/connect/connect/std_data/Mongo3.jar

This change needs to be redesigned and applies only on 10.6 or newer.

The fix is to quote service name parameter, when it is passed to
mysql_upgrade_service subprocess.
