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	9b24fdf4b8	Prevent crash COM_STMT_EXECUTE and invalid stmt_id ... If an invalid stmt_id is passed to COM_STMT_EXECUTE , ProxySQL used to crash due to an assert(). It seems that some buggy clients execute COM_STMT_EXECUTE with an invalid stmt_id after an auto-reconnect. This commit returns an error to the client.

Javier Jaramago Fernández	ab8af07c19	Add 'switching_auth_sent' to 'PROXYSQL INTERNAL SESSION' ... Improved observability for auth switch performed during authentication. The new field 'switching_auth_sent' is only updated when an actual auth switch requested to the client.	2 years ago
René Cannaò	7f57f20e5a	Merge pull request #4430 from sysown/v2.x-4241 ... Added metric MultiplexDisabled_ext #4241	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
René Cannaò	e958946b82	Handle STATUS command without backends ... Handles special queries executed by the STATUS command in mysql cli .

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).

Rahim Kanji	d2b8f7d54e	Fixed code style	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	37f8a50b90	Adding variable mysql-set_parser_algorithm ... Variable mysql-set_parser_algorithm defines which algorithm is used by SetParser for the parsing of SET statements. If value is 1: parse1() is used If value is 2: parse1v2() is used parse1v2() allows also the using a single SetParser per MySQL_Thread to process all SET statements. Regex is compiled only once. set_testing-240-t was also modified to test both algorithms	3 years ago
René Cannaò	86ce115529	Merge pull request #4216 from sysown/v2.x-track_slow_query_vars ... Track some slow query variables	3 years ago
René Cannaò	73ac61b0fb	Remove tracking of log_queries_not_using_indexes ... log_queries_not_using_indexes is not enabled because in MySQL it is *only* a global variable, while in MariaDB is a global *and* session variable . We believe it is not the time to create a lot of exceptions and complex logic for conflicting backend implementations	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

Javier Jaramago Fernández	fe8428e1cf	Remove/Move several explicit 'MySQL_Session' status flag changes ... Setting 'MySQL_Session::status', and 'client_myds::DSS' flags before a call to 'RequestEnd' is redundant, and in some scenarios even dangerous. 'RequestEnd' should handle this for regular sessions.	3 years ago
Javier Jaramago Fernández	ff2e1a2b85	Fix crash when attempting to log failed 'SET NAMES' ... Session 'status' and 'client_myds->DSS' should never be modified for a regular session prior to calling 'RequestEnd'. It's 'RequestEnd' responsibility to appropriately change these statuses after the rest of cleanup operations for the request has taken place, including logging.	3 years ago

René Cannaò	cf6f4f765e	Working prototype of caching_sha2_password ... Now mysql_users.password can store the authentication_string as in MySQL's mysql.user table. Note: this commit also changes SALT_LEN_MAX in SHA-crypt code from 16 to 20 because MySQL caching_sha2_password uses 20 bytes salt	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

Javier Sánchez Parra	1e00e1f021	Assign hostgroup from previous COM_QUERY ... The destination hostgroup assigned from previous COM_QUERY commands is the one used to establish the fast_forward connection. As a result, multiple binlog clients can consume binlog events from different MySQL hostgroups using the same username.	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 Sánchez Parra	fb4740929e	Commands that read the binlog enable fast forward ... For commands BINLOG_DUMP, BINLOG_DUMP_GTID and REGISTER_SLAVE a lot of the features provided by ProxySQL aren't useful, like multiplexing, query parsing, etc. For this reason, ProxySQL enable fast_forward when it receives these commands.	3 years ago
Jared Jetsel	1424967ed6	Receiving COM_BINLOG_DUMP_GTID enabled session fast forwaring ... * If the COM_BINLOG_DUMP_GTID is received, a warning is logged, and then the session_fast_foward is set to true	3 years ago
