Since Item_result enumerations are also used by MariaDB server, we
moved them back to mariadb_com.h.
Item_result is not used in Connector/C 3.3 and above for replication
api.

* extend the client auth plugin API with a new callback
* relax the plugin version check to allow load a plugin with the
same major version, even if the minor versions differ
* implement the protocol extension:
- don't abort at once if the certificate is self signed and
no CA was explicitly specified
- allow it if it passes fingerprint check
- allow it if plugin has hash_password_bin callback, password was
non-empty and the control hash matches server's
Since the server certification option is used by client
only, there is no need to have this flag in server and or
client capabilities. The server itself validates client
certificate depending on the user definition.
This feature allows client applications to register a callback function,
which is called as soon as the server status changes or session_track
information was sent by the server.
Registration is handled via mysql_optionsv() API function:
mysql_optionsv(mysql, MARIADB_OPT_STATUS_CALLBACK, function, data)
The callback function must be defined as follws:
void status_callback(void *data, enum enum_mariadb_status_info type, ..)
Parameters:
- data Pointer passed with registration of callback function
(usually a connection handle)
- type Information type STATUS_TYPE or SESSION_TRACK_TYPE
Variadic Parameters:
if (type == STATUS_TYPE):
- server status (unsigned int)
if (type == SESSION_TRACK_TYPE)
- enum enum_session_state_type track_type - session track type
if (track_type == SESSION_TRACK_SYSTEM_VARIABLES)
- MARIADB_CONST_STRING *key
- MARIADB_CONST_STRING *value
else
- MARIADB_CONST_STRING *value
An example can be found in connection.c (test_status_callback)
ZSTD compression is now supported for connections
to a MySQL Server 8.0.
Compression algorithms are supported via compression
plugins, which can be found in plugins/compress.
The HOSTNAME_LENGTH was increased to 255 bytes in MariaDB 10.6 in
commit https://github.com/MariaDB/server/commit/a3099a3b.
To make it consistent, update HOSTNAME_LENGTH in mariadb-connector-c
to 255 bytes as well.

Added support for passwords > 255 characters.
The new capability flag CLIENT_PLUGIN_AUTH_LENENC_CLIENT_DATA
now indicates that the client can send passwords > 255 characters:
SESSION_TRACK_TRANSACTION_TYPE was renamed to SESSION_TRACK_TRANSACTION_STATE in
a previous commit. To prevent breaking travis testing we added a temporary definition
for SESSION_TRACK_TRANSACTION_TYPE.
Added option MYSQL_OPT_CAN_HANDLE_EXPIRED_PASSWORDS for
mysql_options/mysql_optionsv.
If this option is set, client indicates that he will be able to handle expired passwords by setting the CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS capability flag.
If password expired and CLIENT_CAN_HANDLE_EXPIRED_PASSWORDS is set, the server will not return an error when connecting, but put the connection in sandbox mode, where all commands will return error 1820 (ER_MUST_CHANGE_PASSWORD) unless a new password was set.
Since we frequently update mysqld_error.h error codes from 10.2-server, the ma_error_server.h include file now includes mysqld_error.h (and is just a stub)
- At the moment the following session tracking types are supported:
SESSION_TRACK_SCHEMA
SESSION_TRACK_SYSTEM_VARIABLES
SESSION_TRACK_STATE_CHANGE
SESSION_TRACK_TRANSACTION_CHARACTERISTICS
- New API functions
mysql_session_track_get_next
mysql_session_track_get_first
- changed plugin API to avoid crashes: Oracle/MariaDB changed
structure several times without updating interface version.
- ABI fixes: moved additional net items to net->extension (connection
handler and com_multi buffer)
