Rahim Kanji	bc87d0d901	* For a Describe Portal message, peek at the next message in the extended query frame. If it is an Execute message, indicating that client is sending a Bind/Describe/Execute sequence ... skip processing the Describe Portal.

Javier Jaramago Fernández	6f2798abe0	Fix memory leak in 'ProxySQL_Admin::stats___mysql_global' - Closes #4976 ... The resource leak was associated to prepared statements (sqlite3_stmt). Since the detection of these leaks is tricky, because the resources held by 'SQLite3' never lose their references, a helper type ('stmt_unique_ptr') and a safer variation for 'prepare_v2' have been introduced. This helper type should automatically handle the lifetime of the statements, avoiding these kind of leaks in the future. The non-safe alternative has been flagged as 'deprecated', so it can be easily identified in later refactors or slowly removed during development.	8 months ago

René Cannaò	f9575b7ee9	Addressing minor issue on Readyset Monitoring ... - Renamed ReadySet to Readyset - fixed incorrect status variable - added missing newlines	10 months ago
René Cannaò	d641ca89be	First POC for integration with ReadySet ... Monitor is able to detect if a backend is a ReadySet server, and it enables special monitoring. The special monitoring hacks replication lag checks: a ReadySet server is "monitored for replication lag" , but it has a special query and a special handler. The query for check is "SHOW READYSET STATUS" , and the `Status` line is processed: * Online: the backend is configured as ONLINE * Maintenance* : the backend is configured as OFFLINE_SOFT * anything else, or failed check: SHUNNED A new monitor table is also added: `readyset_status_log` . It has a similar structure of `mysql_server_replication_lag_log` , but instead of storing `repl_lag` (replication lag) the full output of `SHOW READYSET STATUS` is saved as a JSON (that can be queried using `JSON_EXTRACT()`	10 months ago
