Javier Jaramago Fernández	67624b8569	Fix compilation warning for 'strncpy' due string truncation ... As per the GCC manual, calls to 'strn*' function family shall be replaced by 'memcpy' when truncation (no null termination) is expected.	6 months ago
Javier Jaramago Fernández	639f9d0c74	Fix potential 'use-after-free' by 'SHOW PROCESSLIST' ... Accesses by 'stats___mysql_processlist' to 'myconn->query.ptr' could lead to invalid memory accesses, as the pointed query could already have been free by the session after being issued.	6 months ago
Wazir Ahmed	5219d4be93	processlist: Prevent crash due to SQLITE_TOOBIG ... - Add new mysql/pgsql variable `processlist_max_query_length`. - Min: 1K - Max: 32M - Default: 2M - Truncate current query based on the configuration before inserting into `stats_*_processlist` tables. - Refactor/fix code related to other processlist configurations. 1. `session_idle_show_processlist` value was not updated in `ProxySQL_Admin.variables`. 2. Pass processlist config as an argument to `MySQL_Threads_Handler::SQL3_Processlist` instead of using thread-local variables. Signed-off-by: Wazir Ahmed <wazir@proxysql.com>	6 months ago

Javier Jaramago Fernández	d49a96dade	Enforce 'CLIENT_DEPRECATE_EOF' capability match for fast-forward ... - Ensures matching for 'CLIENT_DEPRECATE_EOF' capability when creating or acquiring backend conns for 'fast-forward' sessions. - Since 'CLIENT_DEPRECATE_EOF' capability isn't enforced on backend connections for regular sessions, a mismatch between client and backend capabilities is possible. A verification has been introduced when a session switches to 'fast-forward', in case of capabilities mismatch, an error is logged and client disconnected.	1 year ago

Javier Jaramago Fernández	ac3e75244c	Fix leak of SSL caches for auxiliary threads ... Whenever a thread creates MySQL connections using SSL params the thread-local caches are populated. These thread-local resources need to be free on thread exit via 'mysql_thread_end', otherwise these objects will be leak. This is not relevant for the fixed size thread-pools, but it's for workloads making use of temporary/auxiliary threads.	1 year ago

Add new config option ('mysql-connpool_match_client_deprecate_eof') that allows to control whether to enforce a match between fronted and backend connections for 'CLIENT_DEPRECATE_EOF' capability.

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	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	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.	3 years ago
