`add_anonymous.inc`, update `delete_anonymous.inc`.
- Added test case with `--skip-name-resolve`

In case the option require_secure_transport is on the user can't
establish a secure ssl connection over TCP protocol. Inability to set up
a ssl session over TCP was caused by the fact that a type of client's
connection was checked before ssl handshake performed (ssl handshake
happens at the function acl_authenticate()). At that moment vio type has
the value VIO_TYPE_TCPIP for client connection that uses TCP transport.
In result, checking for allowable vio type for fails despite the fact
that SSL session being established. To fix the issue move checking of
vio type for allowable values inside the function
parse_client_handshake_packet()
right after client's capabilities discovered that SSL is not requested
by the client.
Replacing my_casedn_str() called on local char[] buffer variables
to CharBuffer::copy_casedn() calls.
This is a sub-task for MDEV-31531 Remove my_casedn_str()
Details:
- Adding a helper template class IdentBuffer (a CharBuffer descendant),
which assumes utf8 data. Like CharBuffer, it's initialized to an empty
string in the constructor, but can be populated with lower-cased data
later.
- Adding a helper template class IdentBufferCasedn, which initializes
to lower case right in the constructor.
- Removing char[] buffers, replacing them to IdentBuffer and IdentBufferCasedn.
- Changing the data type of "db" and "table" parameters from
"const char*" to LEX_CSTRING in the following functions:
find_field_in_table_ref()
insert_fields()
set_thd_db()
mysql_grant()
to reuse IdentBuffer easeir.
The error message for user connections using insecure transport when secured transport is required is very uninformative and doesn't mention the requirement of secure
transport at all.
To make the error message more relevant, introduce a new error
'ER_SECURE_TRANSPORT_REQUIRED', copy of MySQL error message with the
error code 08004 (SQL-server rejected establishment SQL-connection).
Move the code of 'require_secure_transport' to be executed before
authentication verification, as it's not part of authentication but
rather verifying if connection should be allowed in the first place.

Since TLS server certificate verification is a client
only option, this flag is removed in both client (C/C)
and MariaDB server capability flags.
This patch reverts commit 89d759b93e
(MySQL Bug #21543) and stores the server certificate validation
option in mysql->options.extensions.
lower_case_table_names=2 means "table names and database names are
stored as declared, but they are compared in lowercase".
But names of objects in grants are stored in lowercase for any value
of lower_case_table_names. This caused an error when checking grants
for objects containing uppercase letters since table_hash_search()
didn't take into account lower_case_table_names value
This patch is the result of running
run-clang-tidy -fix -header-filter=.* -checks='-*,modernize-use-equals-default' .
Code style changes have been done on top. The result of this change
leads to the following improvements:
1. Binary size reduction.
* For a -DBUILD_CONFIG=mysql_release build, the binary size is reduced by
~400kb.
* A raw -DCMAKE_BUILD_TYPE=Release reduces the binary size by ~1.4kb.
2. Compiler can better understand the intent of the code, thus it leads
to more optimization possibilities. Additionally it enabled detecting
unused variables that had an empty default constructor but not marked
so explicitly.
Particular change required following this patch in sql/opt_range.cc
result_keys, an unused template class Bitmap now correctly issues
unused variable warnings.
Setting Bitmap template class constructor to default allows the compiler
to identify that there are no side-effects when instantiating the class.
Previously the compiler could not issue the warning as it assumed Bitmap
class (being a template) would not be performing a NO-OP for its default
constructor. This prevented the "unused variable warning".
SUPER privilege used to allow various actions that were alternatively
allowed by one of BINLOG ADMIN, BINLOG MONITOR, BINLOG REPLAY,
CONNECTION ADMIN, FEDERATED ADMIN, REPL MASTER ADMIN, REPL SLAVE ADMIN,
SET USER, SLAVE MONITOR.
Now SUPER no longer does that, one has to grant one of the fine-grained
privileges above to be to perform corresponding actions.
On upgrade from MariaDB versions 10.11 and below all the privileges
above are granted automatically if the user has SUPER.
As a side-effect, such an upgrade will allow SUPER-user to run SHOW
BINLOG EVENTS, SHOW RELAYLOG EVENTS, SHOW SLAVE HOSTS, even if he wasn't
able to do it before the upgrade.
