Rahim Kanji	e1c489acb1	* If the backend server has CLIENT_DEPRECATE_EOF enabled, and the client does not support CLIENT_DEPRECATE_EOF, warning_count will be '0' in intermediate EOF packet. * Suppress the display of warning counts in the "SHOW WARNINGS" statement.	2 years ago
Rahim Kanji	045d6bcaeb	* Execute all test cases with 'CLIENT_DEPRECATE_EOF' both enabled and disabled. * Introduced 'ps_type' enum to differentiate between preparing a statement and executing a statement * Fixed issue where the warning count fails to reset when the SET statement generates a warning. * Resolved the issue where the 'server_status' and 'warning count' were not accurately represented in the statement. * Replaced 'mysql_warning_count' with 'mysql_stmt_warning_count' for retrieving the warning count in statements. * Added 'handle_warning' field in hostgroup_attributes TAP test * Updated warnings TAP test	2 years ago
Rahim Kanji	dae3d669b9	* Setting 'warning_count' as soon as query is executed. * 'MySQL_Connection::warning_count' will be globally employed for managing multiplexing control and transmitting the warning count to the client * Fixed prepare statement bug: When preparing, if the digest matches, the result set is retrieved from the cache and sent to the client. Note: Currently using 'mysql_warning_count' to retrieve the warning count for prepared statement.	2 years ago
Rahim Kanji	05208e2839	* Update warning_count as soon as query is executed.	2 years ago
Rahim Kanji	743cd502a5	* Updated variable name from 'mysql-query_cache_with_warnings_support' to 'mysql-query_cache_handle_warnings' * Introduced global variable 'mysql-handle_warnings' to control warning support in ProxySQL * Included 'handling_warnings' flag in the 'mysql_hostgroup_attributes' table (hostgroup_settings). This flag holds top priority and can override the value of the global variable 'mysql_handle_warnings'.	2 years ago
Rahim Kanji	b588798a08	Few fixes	2 years ago
Rahim Kanji	6b295477d6	Enhanced Warnings handling in ProxySQL: * Implemented 'SHOW WARNINGS' and 'SHOW COUNT() FROM WARNINGS' query handling. When a query produces warnings, the warning count is now included in the query response. Additionally, a new variable 'mysql-query_cache_with_warnings_support' has been introduced for the query cache feature: * A value of '0' means that if a query execution produces warnings, the resultset will not be saved in the query cache. * A value of '1' indicates that if a query produces warnings, the resultset will be saved in the query cache, but the warning count in that resultset will be set to '0'. ** Note: * Warning handling is dependent on the query digest and 'mysql-query_digests' must be enabled for it to work. * Warnings saved in logfile ['mysql-log_mysql_warnings_enabled'] and the current feature can work in conjunction with each other.	2 years ago
Javier Jaramago Fernández	bb40e9e431	Fix 'COMMIT\|ROLLBACK' forwarding to backend connections - Closes #4264 These commands are now forwarded to the backend connections from a session with potential transaction statuses, using the following priority order: 1. Connections flagged with 'SERVER_STATUS_IN_TRANS', or 'autocommit=0' when 'autocommit_false_is_transaction' is set. 2. Connections with 'autocommit=0' holding a 'SAVEPOINT'. 3. Connections with 'unknown transaction status', e.g: connections with errors.	3 years ago
René Cannaò	db632cd7f5	Preserve STATUS_MYSQL_CONNECTION_COMPRESSION after connection reset In MySQL_Connection::reset() we were forgetting the value of STATUS_MYSQL_CONNECTION_COMPRESSION. De-facto disabling compression if it was enabled.	3 years ago
Rahim Kanji	ff722142bf	SSL support on Unix Socket reinstated	3 years ago
Rahim Kanji	a1fcf5d94f	Added SSLKeylog in ProxySQL Modules	3 years ago
Rahim Kanji	8f899e34f9	Added support for SSLKEYLOGFILE * 'admin-ssl_keylog_file' variable has been introduced to allow users to specify the path for the SSLKEYLOG file. The file path can be an absolute path or relative to the ProxySQL data directory. * Assigning an empty path to the 'admin-ssl_keylog_file' variable signifies that the SSLKEYLOG file feature is disabled. * In case an invalid path is provided for the SSLKEYLOG file, ProxySQL will automatically revert to the last valid path value. * 'PROXYSQL FLUSH LOGS' command can be used to rotate SSLKEYLOG file. # Conflicts: # lib/mysql_connection.cpp	3 years ago
Rahim Kanji	cd352ff141	Disable SSL and Compression for UNIX Socket	3 years ago
Rahim Kanji	3865c81873	DNS Cache module has been updated so that it no longer regards the UNIX socket path as a hostname.	3 years ago
René Cannaò	069140f79e	Automatically start a transaction when running a query This commit also introduces 2 output for PROXYSQL INTERNAL SESSION: - active_transactions - transaction_started_at Enhanced the TAP tests to also verify the above metrics	3 years ago
René Cannaò	e487ddf8ec	Set correct backend encryption when switching to fast_forward When receiving MYSQL_COM_BINLOG_DUMP , MYSQL_COM_BINLOG_DUMP_GTID or MYSQL_COM_REGISTER_SLAVE , proxysql automatically switches to fast_forward . Although it is important to correctly configure "encrypted" in the backend data stream if needed. Used PMC-10005 for reference , as this is implemented similarly in many parts of the code. During the switch proxy_info() now also reports the client and the command received.	3 years ago
René Cannaò	f3c604eb84	Implemented mysql_hostgroup_attributes.multiplex If mysql_hostgroup_attributes.multiplex: - 0 : multiplexing is always disabled - 1 : multiplexing is enabled for the hostgroup, but other criteria can disable multiplexing (transaction, temp tables, query rules, etc)	3 years ago

Javier Jaramago Fernández	67fac0b761	Fix 'compression' integration with 'fast_forward' sessions - Compression flag is now propagated from client to backend connection when the backend connection is being created for a 'fast_forward' session. In case of client trying to connect without compression, to a server configured with compression, we fallback to an uncompressed connection. - After a 'MySQL_Session' has obtained a connection for a 'fast_forward' session, i.e, the one-to-one relationship between the client and backend connection has been stablished, we completely disable the compression 'STATUS_MYSQL_CONNECTION_COMPRESSION' flag from the client 'MySQL_Connection'.	3 years ago
Rahim Kanji	8ebb990002	Resolves Issue 3991 * Added support for @@local * Added support for optimizer_use_condition_selectivity * Updated test cases	3 years ago
Javier Jaramago Fernández	bcc6532d66	Modify previous impl for 'auto_increment_delay_multiplex_timeout_ms' and fix 'connection_delay_multiplex_ms' This commit contains an implementation rework and a fix: - Impl for 'auto_increment_delay_multiplex_timeout_ms' has been reworked in favor of reusing 'wait_until' to share logic with previous 'connection_delay_multiplex_ms' variable. - Fix previous 'connection_delay_multiplex_ms' behavior preventing connection retaining when traffic unrelated to target hostgroup is being received by the session.	4 years ago
Javier Jaramago Fernández	a67db17709	Fix current 'auto_increment_delay_multiplex_timeout_ms' behavior #3923	4 years ago
René Cannaò	f960a4d9b7	Merge pull request #3903 from sysown/v2.x-tests_220619 V2.x tests 220619	4 years ago
René Cannaò	f7d8824379	Trying to work around MySQL bug 107875 Because of MySQL bug https://bugs.mysql.com/bug.php?id=107875 , autocommit=0 can "create a transaction" even if SERVER_STATUS_IN_TRANS is not set. This means that a SAVEPOINT can be created in a "transaction" created with autocommit=0 but without SERVER_STATUS_IN_TRANS . This commit takes also care of scenarios when autocommit=0 was switched back to autocommit=1 when a SELECT was executed while variable mysql-enforce_autocommit_on_reads was false. MySQL_Session::NumActiveTransactions() now accepts a flag to check for savepoints.	4 years ago
René Cannaò	61b32de42f	Solve bug #3749 and improve testing In MySQL_Connection::IsActiveTransaction: in the past we were incorrectly checking STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT and returning true in case there were any savepoint. Although flag STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT was not reset in case of no transaction, thus the check was incorrect. We can ignore STATUS_MYSQL_CONNECTION_HAS_SAVEPOINT for multiplexing purpose in IsActiveTransaction() because it is also checked in MultiplexDisabled()	4 years ago
René Cannaò	227e045aa4	Improved mysql-init_connect-t.cpp for PMC-10003 PMC-10003: Retrieved a resultset while running a simple command using async_send_simple_command() . async_send_simple_command() is used by ProxySQL to configure the connection, thus it shouldn't retrieve any resultset. A common issue for triggering this error is to have configure mysql-init_connect to run a statement that returns a resultset.	4 years ago
René Cannaò	8d2a88a746	Merge pull request #3856 from sysown/v2.x-rm_duplicate_mysql_err_counts Fix duplicate counting of MySQL errors for client conns	4 years ago
René Cannaò	9275e2858d	Track NO_BACKSLASH_ESCAPES Track NO_BACKSLASH_ESCAPES in case it is changed: - using SET sql_mode by the client - directly on the backend (for example default sql_mode, or an sql_mode set from another variable)	4 years ago

René Cannaò	2ba9c401f1	Bug fixes in the new implementation of tracking mysql variables Better parsing of SET SQL_LOG_BIN . SQL_LOG_BIN is now managed by the same functions that handle boolean variables instead of the now deprecated MySQL_Session::handler_WCD_SS_MCQ_qpo_Parse_SQL_LOG_BIN() For naming convention, enum value SQL_LOG_BIN was renamed to SQL_SQL_LOG_BIN In MySQL_Thread we also deprecated match_regexes[0] , previously used to parse `set sql_log_bin`. Functions Variable::fill_server_internal_session() and Variable::fill_client_internal_session() seems to handle sql_log_bin as a special value. This exception was removed. Fixed a bug in MySQL_Session::generate_proxysql_internal_session_json() where when backend variables needed to be generated, fill_client_internal_session() was incorrectly called instead of fill_server_internal_session() , leading to incorrect values reported by `PROXYSQL INTERNAL SESSION`	4 years ago
