René Cannaò	4c1f4a8d82	Enhancements on AWS Aurora module ... Added 2 new status variables: - queries_with_max_lag_ms__delayed - queries_with_max_lag_ms__total_wait_time_us Do not get replication lag from replicas if the value is 0 Fixed an error in the computation of max_lag_ms	7 years ago

René Cannaò	8c4b70a557	Added capability to lock hostgroup ... This should fix a lot of issues related to failed parsing of SET statement. This and the two 2 previous commits introduce several status variables, and a new configuration variable: mysql-set_query_lock_on_hostgroup Possible values for mysql-set_query_lock_on_hostgroup: - 0 : legacy behavior , before 2.0.5 - 1 : (default) . SET statements that cannot be parsed correctly disable both multiplexing AND routing. Attempting to route traffic while a connection is linked to a specific backend connection will trigger an error to be returned to the client	7 years ago

René Cannaò	0831740e45	Several enhancements on Query logger ... Enhancements: - added metrics rows_affected and rows_sent - added global variable mysql-eventslog_default_log : if 1 , logging is enabled for every query unless explicitly disabled in mysql_query_rules.log . Default is 0 - added global variable mysql-eventslog_format : default is 1 (legacy format). A value of 2 enables logging in JSON format. Issue #871 Changing value at runtime causes the current file to be closed and a new one created - fixed logging for prepared statements: till 2.0.5 only some percentage of prepared statements was correctly logged Extended tables stats_mysql_query_digest and stats_mysql_query_digest_reset to also include sum_rows_affected and sum_rows_sent Extended `eventslog_reader_sample.cpp` to support the new enhancements	7 years ago
René Cannaò	9ed7094cfe	Implemeting of more locking in SELECT statements ... SELECT ... FOR SHARE SELECT ... LOCK IN SHARE MODE SELECT ... FOR (UPDATE|SHARE) [OF ...] (NOWAIT|SKIP LOCKED)	7 years ago
René Cannaò	528d8cac38	Improved debugging ... Added new command `PROXYSQL INTERNAL SESSION` that clients can execute to receive internal information about their own connection in JSON format.

Added new mysql variable `mysql-show_processlist_extended` that determine the content of `stats_mysql_processlist.extended_info`: - 0 : no info - 1 : JSON format - 2 : JSON format with pretty printing	7 years ago
René Cannaò	9788643f38	Track NO_BACKSLASH_ESCAPES #1738 ... `SERVER_STATUS_NO_BACKSLASH_ESCAPES` is now tracked. `set sql_mode` is executed immediately if client executes `set sql_mode` specifying `NO_BACKSLASH_ESCAPES`. A backend connection with `SERVER_STATUS_NO_BACKSLASH_ESCAPES` enabled has multiplexing immediately disabled.	7 years ago

René Cannaò	d04ee3d385	Remove all references to PS handling before 1.4 ... Handling of prepared statements changed a lot in 1.4 , as a lot of code was rewritten. Old code was still present, and was possible to toggle it on and off based on PROXYSQL_STMT_V14 .
