Added new option MARIADB_OPT_RPL_REGISTER_REPLICA which expects
two parameters, host and port. When this option was set, rpl_open
will send a COM_REGISTER_SLAVE command with server_id, host and
port to the connected server. This information can be retrieved
by "SHOW SLAVE STATUS" command.
Example:
rc= mysql_optionsv(mysql, MARIADB_OPT_RPL_REGISTER_REPLICA,
"myhost", 123);
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.
- For reconnection/and multi host tests specify also socket location,
since mtr doesn't use default socket for localhost connections
- parse_connection_string now returns NULL for empty password in
curly braces
host parameter of mysql_real_connect (and corresponding configuration
settings MYSQL_OPT_HOST for mysql_options() api call and host key in
configuration files) now accepts to specify multiple hosts and ports.
When establishing a connection, the list of specified hosts is run
through until a connection can be established. If no connection
can be established to any of the specified hosts, an error is returned.
Specifications for multiple hosts/ports:
- hostname and port must be seperated by a colon (:)
- IPv6 addresses must be enclosed within square brackets
- hostname:port pairs must be be seperated by a comma (,)
- if only one host:port was specified, the host string needs to end
with a comma.
- if no port was specified, the default port will be used.
Examples for failover host string:
host=[::1]:3306,192.168.0.1:3306,test.example.com
host=localhost:3306,
A connection string contains key/value pairs, separated by a semicolon
as used in ODBC. Supported keys are all configuration options which can
be used in MariaDB configuration files. For a complete list check
https://github.com/mariadb-corporation/mariadb-connector-c/wiki/config_files#configuration-options.
The connection string must contain at least one semicolon, otherwise
it wil be interpreted as hostname. Unknown or invalid keys will be ignored.
To connect via connection string, the following methods might be used:
- by specifing connection option in configuration file:
connection=host=localhost;ssl_enforce=1;
- by using mariadb_connect() macro
mariadb_connect(mysql, "host=localhost;ssl_enforce=1")
- by passing connection string in host parameter to mysql_real_connect
mysql_real_connect(mysql, "host=localhost;ssl_enforce=1", NULL, NULL, NULL, 0, NULL, 0)
When receiving a ROTATE event, the offset of filename
was not computed correctly. Similiar to the
BINLOG_CHECK_POINT event filename will also be stored
in MARIADB_RPL handle
Beside already supported asynchronous replication
the replication/binlog API now supports semi
synchronous replication:
If an event contains a semi synchronous indicator (0xEF)
behind status byte and acknowledgement flag is set,
mariadb_rpl_fetch() automatically sends an acknowledge
message to the connected primary server.
If mariadb_stmt_execute_direct fails, we need to set the number
of parameters (obtained by response packet of mysql_stmt_prepare)
back to the number of prebinded parameters to avoid memory
overrun.
This fix also includes several adress-sanitizer bugs in unit tests
of Connector/C.
If cursor type is set to read only, and SERVER_STATUS_CURSOR_EXISTS
flag was not set in the server_status of EOF packet, the assumption
was made that a single result set will follow which will be stored
by a call to mysql_stmt_store_result().
As the example in the bug report shows, this is not always the case,
since a stored procedure call might also unset the CURSOR flag and
will always return multiple result sets. In this case it will be
handled now as "normal" unbuffered result set.
Added new option MARIADB_OPT_RESTRICTED_AUTH (and corresponding
"restricted-auth" option for configuration files) which specifies
on or more comma spearated authentication plugins which are allowed
for authenication.
If the server asks for an authentication plugin not listed in this
option the connect attempt will fail with error CR_PLUGIN_NOT_ALLOWED.
