Rahim Kanji	8c92f9292a	A hostgroup can now be configured to have a maximum number of online servers simultaneously. Once this limit is reached, any new connections attempting to access the connection pool will be denied, and existing connections will gradually be reassigned to the available connection pool until the number of online servers is reduced to meet or fall below the specified maximum.	2 years ago

René Cannaò	8ab51c65e7	ssl_params: use NULL instead of empty string #4466 ... If values in mysql_servers_ssl_params are empty strings, they needs to be passed as NULL arguments in mysql_ssl_set() and mysql_options() Closes #4466	2 years ago
René Cannaò	548ededd4f	Include MySQLServers_SslParams in MySQL_Connection ... This allows to preserve the parameters, and output in the error log if needed	2 years ago

René Cannaò	41cd740701	Added metric MultiplexDisabled_ext #4241 ... In the output of PROXYSQL INTERNAL SESSION and stats_mysql_processlist.extended_info , MultiplexDisabled was only returning the output of MySQL_Connection::MultiplexDisabled() . If there was a transaction, or an error, multiplexing was disabled but MultiplexDisabled() was still reporting false. Therefore it was necessary to also check server_status flag and last_errno. This commits intruduces MultiplexDisabled_ext , that reports the output of: MySQL_Connection::MultiplexDisabled() || MySQL_Connection::isActiveTransaction() This should make troubleshooting easier. Also, removed any reference to deprecated STATUS_MYSQL_CONNECTION_TRANSACTION . Closes #4241	2 years ago

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	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

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
