René Cannaò	fce7a0204c	Handle binary protocol resultset with ERR #3547 ... This commit add the support of ERR packet in binary protocol resultset, for example due to MAX_EXECUTION_TIME while running a prepared statement. It also changes how EOF packets are added: instead of writing the EOF in the resultset buffer, the EOF packet is written in its own packet. This allows to easily remove it if needed. It also fix what seems (not sure) a bug in MariaDB client library, where if a prepared statement is interrupted it cannot be executed again	5 years ago

René Cannaò	a1c232039f	Reduce length of mysql_bug_102266 #3501 ... In #3285 we increased the amount of data sent to the backend during connection time using MYSQL_OPT_CONNECT_ATTR_ADD , in order to avoid MySQL bug 102266 . See #3276 . Although this create a lot of noise in ProxySQL error log and MySQL error log, because the connection attributes are too long and they get truncated. This PR reduces the length of connection attributes	5 years ago

René Cannaò	bd5d882770	Fixing an inifinite loop in case of multi-statements and closed backend connection ... If a backend connection was terminated in the middle of the execution of multiple statements in a multi-statements command, the worker thread was entering an infinite loop. Furthermore, this commit disables query retry in case of multi-statements if the first one completed successfully This fixes #3339 This commit is the port to 2.1 of 90a4922ed8	5 years ago

René Cannaò	2b23bd3102	Avoid MySQL bug 102266 #3276 ... ProxySQL is sending a lot of data to MySQL server using CLIENT_CONNECT_ATTRS in order to not hit MySQL bug https://bugs.mysql.com/bug.php?id=102266 . See also https://github.com/sysown/proxysql/issues/3276	5 years ago
René Cannaò	598331cff9	When calling mysql_change_user set collation to default for the given charset if collation ID is greater or equal than 255 (utf8mb4_0900_ai_ci) ... We call mysql_options with MYSQL_SET_CHARSET_NAME if collation ID >= 255 . This to solve the problem of MySQL server returning an Access denied if the backend doesn't support a collation during mysql_change_user	5 years ago
René Cannaò	2519551cb4	Do not search charset in mysql_real_connect if already set ... In mysql_init() charset is set to NULL . In mysql_read_connect() charset is not changed if already set This allows proxysql to change it outside the library	5 years ago

René Cannaò	7921e130d2	Third commit to buffer resultsets in Prepared Statements ... * MySQL_ResultSet() stores a pointer to the PS * MySQL_ResultSet::init_with_stmt() doesn't need anymore the pointer to the PS Furthermore, it isn't anymore an "init" but an end (we will rename it) * Added MySQL_ResultSet::add_row(MYSQL_ROWS *rows) for PS only * MySQL_Protocol::generate_pkt_row3() accepts an optional row length. If passed, it will know the length of the row without computing it * MyRS initialized during ASYNC_STMT_EXECUTE_STORE_RESULT_START * Implemented throttling during ASYNC_STMT_EXECUTE_STORE_RESULT_START * MySQL_Connection::process_rows_in_ASYNC_STMT_EXECUTE_STORE_RESULT_CONT() always generates a heartbeat. For now unnecessary, and we will better tune it later * test_ps_async-t.cpp tunes mysql-threshold_resultset_size to trigger buffering More testing is required	5 years ago
René Cannaò	5c0a732d8a	Second commit to buffer resultsets in Prepared Statements ... So far this seems to work, although it is dropping most of the rows. The rows are lost intentionally up to this commit.	5 years ago
