Added a new structure MARIADB_X509_INFO, which
contains information about servers certificate.
The information can be obtained via mysql_get_infov API
function:
MARIADB_X509_INFO *info;
mariadb_get_infov(mysql, MARIADB_TLS_PEER_CERT_INFO, &info);
Resetting a statement will result in an error, if another (different)
statement has a pending unbuffered result set (CR_COMMANDS_OUT_OF_SYNC).
Freeing a statement result set will return an error, if the statement
has no result set or was not executed (CR_STMT_NO_RESULT).
mysql_old_password is disabled by default (setting DISABLED YES),
but can be used if the plugin was added to the list of restricted
authentication plugins (via mysql_optionsv using option
MARIADB_OPT_RESTRICTED_AUTH).
With MDEV-30366, server now permit to send a result-set containing generated id and Affected rows for each bulk operation. This feature can be enabled with option MARIADB_OPT_BULK_UNIT_RESULTS when server supports it.
This reverts 395641549ac7..536d9e2b9e5b, in particular:
8dffd56936 MDEV-31857 enable MYSQL_OPT_SSL_VERIFY_SERVER_CERT by default
a99570c118 MDEV-31855 SSL cert validation protocol extension
9aa15e72a7 TLS fingerprint
and related commits
because the default value of every option is 0
(option and option.extension are bzero-ed to reset),
tls_verify_server_cert was renamed to tls_allow_invalid_server_cert
with the default value of 0, "do not allow".
API didn't change, it's still MYSQL_OPT_SSL_VERIFY_SERVER_CERT
Skip character set tests which set character set
during handshake, since MaxScale sends utf8mb4 via
session_track information in handshake OK packet.
(https://jira.mariadb.org/browse/MXS-4898).
When checking for a semi sync indication header, we need also check if
the undocumented session variable @rpl_semi_sync_slave was set.
Otherwise the timestamp of the event could contain values which match
the 2 bytes of the semi sync header.
Since the variable rpl_semi_sync_slave and it's behavior is not documented,
a new option MARIADB_RPL_SEMI_SYNC was added.
If prepare step failed in mariadb_stmt_execute_direct now both
mysql_stmt_error and mysql_error return the error message from
prepare step instead of error message of execute.
When resetting the connection with mysql reset_connection(), the
server_status must be checked and any other resultsets that mayi
exist must be removed.
