MDEV-31477: The JSON_KEY_VALUE function should print an error message
if json_doc is passed as a variable
Analysis:
JSON_KEY_VALUE() uses Json_path_extractor::extract() to reach to path and
extract values. One error it only returns true, but no error.
Fix:
report error when there is error in scanning json document.

MDEV-30145: JSON_TABLE: allow to retrieve the key when iterating on JSON
objects
Idea behind implementation:
We get the json object specified by the json path. Then, transform it into
key-value pairs by going over the json. Get each key-value pair
one-by-one and return the result.

MDEV-28343: sys.create_synonym_db fails with ER_VIEW_SELECT_TMPTABLE when schema contains temporary tables
- MDEV-28342 raised the error in case temporary table shadows base table
- Now we are allowed to shadow base tables with temporary tables and
`sys.create_synonym_db()` can easily check for existance of temporary table and
ignore view creation, since it is not supported to create view from
temporary table.

This commit updates sysschema to work with the new behaviour of show
tables and information_schema.tables table showing temporary tables for
current connection.

MDEV-12459 Get temporary tables visible to the IS.tables for current connection
Additionally fixes the bugs uncovered in:
- `MDEV-28332: Alter on temporary table causes ER_TABLE_EXISTS_ERROR note`
Since there is no `warning` issued by shadowing of base table, this MDEV
is irrelevant. Keeping for review purposes and for future development
in case shadowing is going to be implemented
- `MDEV-28334: SHOW TABLE STATUS shows all temporary tables ignoring database and conditions`
- `MDEV-28453: SHOW commands are inconsistent for temporary tables`
We achieve this by creating a "stub" table in the second scenario
while opening the table, where t2 does not exist but needs to import
from t1. The "stub" table is similar to a table that is created but
then instructed to discard its tablespace.
We include tests with various row formats, encryption, with indexes
and auto-increment.
MDEV-30188: Ensure all binlog* variables are visible as system variables
Turn the remaining three `binlog*` options binlog_do_db, binlog_ignore_db,
binlog_rows_event_max_size into global variables so that they can be
visible from the SQL user level. This is for audit / secure
configuration check purposes.
Create new MTR tests to make sure that the newly created global
variables can be visible from the command line interface.
Behavior before the code change:
MariaDB [(none)]> SHOW GLOBAL VARIABLES WHERE
-> Variable_name LIKE 'binlog_do_db' OR
-> Variable_name LIKE 'binlog_ignore_db' OR
-> Variable_name LIKE 'binlog_row_event_max_size';
Empty set (0.001 sec)
Behavior after the code change:
MariaDB [(none)]> SHOW GLOBAL VARIABLES WHERE
-> Variable_name LIKE 'binlog_do_db' OR
-> Variable_name LIKE 'binlog_ignore_db' OR
-> Variable_name LIKE 'binlog_row_event_max_size';
+---------------------------+-------+
| Variable_name | Value |
+---------------------------+-------+
| binlog_do_db | |
| binlog_ignore_db | |
| binlog_row_event_max_size | 8192 |
+---------------------------+-------+
3 rows in set (0.001 sec)
Note:
For `binlog_do_db` and `binlog_ignore_db`, we add a new class
`Sys_var_binlog_filter` to handle the dynamically-composable command line
options for `binlog_do_db` and `binlog_ignore_db`. Below
is the motivation:
When the users start the server with the option
--binlog-do-db="database1" --binlog-do-db="database2"
The expected behavior is that the system should allow replication for
both `database1` and `database2`, which is the logic of the original
code.
However, when turning the variables into system variables, the
functionality does not exist any more, since system variables will only
handle the last occurrence of the option, and in this case, the system
will only be able to handle `database2`.
