Michael Widenius	ab0905c6d7	This is based on the userstatv2 patch from Percona and OurDelta. ... The original code comes, as far as I know, from Google (Mark Callaghan's team) with additional work from Percona, Ourdelta and Weldon Whipple. This code provides the same functionallity, but with a lot of changes to make it faster and better fit the MariaDB infrastucture. Added new status variables: - Com_show_client_statistics, Com_show_index_statistics, Com_show_table_statistics, Com_show_user_statistics - Access_denied_errors, Busy_time (clock time), Binlog_bytes_written, Cpu_time, Empty_queries, Rows_sent, Rows_read Added new variable / startup option 'userstat' to control if user statistics should be enabled or not Added my_getcputime(); Returns cpu time used by this thread. New FLUSH commands: - FLUSH SLOW QUERY LOG - FLUSH TABLE_STATISTICS - FLUSH INDEX_STATISTICS - FLUSH USER_STATISTICS - FLUSH CLIENT_STATISTICS New SHOW commands: - SHOW CLIENT_STATISTICS - SHOW USER_STATISTICS - SHOW TABLE_STATISTICS - SHOW INDEX_STATISTICS New Information schemas: - CLIENT_STATISTICS - USER_STATISTICS - INDEX_STATISTICS - TABLE_STATISTICS Added support for all new flush commands to mysqladmin Added handler::ha_... wrappers for all handler read calls to do statistics counting - Changed all code to use new ha_... calls - Count number of read rows, changed rows and rows read trough an index Added counting of number of bytes sent to binary log (status variable Binlog_bytes_written) Added counting of access denied errors (status variable Access_denied_erors) Bugs fixed: - Fixed bug in add_to_status() and add_diff_to_status() where longlong variables where threated as long - CLOCK_GETTIME was not propely working on Linuxm client/mysqladmin.cc: Added support for all new flush commmands and some common combinations: flush-slow-log flush-table-statistics flush-index-statistics flush-user-statistics flush-client-statistics flush-all-status flush-all-statistics configure.in: Added checking if clock_gettime needs the librt.

Michael Widenius	cd3047fc89	Updated documentation files to reflect MariaDB and not the Maria storage engine or MySQL ... Added (rewritten) patch from Percona to get extended statistics in slow.log: - Added handling of 'set' variables to set_var.cc. Changed sql_mode to use this - Added extra logging to slow log of 'Thread_id, Schema, Query Cache hit, Rows sent and Rows examined' - Added optional logging to slow log, through log_slow_verbosity, of query plan statistics - Added new user variables log_slow_rate_limit, log_slow_verbosity, log_slow_filter - Added log-slow-file as synonym for 'slow-log-file', as most slow-log variables starts with 'log-slow' - Added log-slow-time as synonym for long-query-time Some trivial MyISAM optimizations: - In prepare for drop, flush key blocks - Don't call mi_lock_database if my_disable_locking is used KNOWN_BUGS.txt: Updated file to reflect MariaDB and not the Maria storage engine README: Updated file to reflect MariaDB mysql-test/r/log_slow.result: Test new options for slow query log mysql-test/r/variables.result: Updated result (old version cut of things at 79 characters) mysql-test/t/log_slow.test: Test new options for slow query log sql/Makefile.am: Added log_slow.h sql/event_data_objects.cc: Removed not needed test for enable_slow_log (is done when the flag is tested elsewhere) sql/events.cc: Use the general make_set() function instead of 'symbolic_mode_representation' sql/filesort.cc: Added status for used query plans sql/log.cc: Reset counters if no query_length (from Percona's patch; Not sure if needed, but can do no harm) Added extra logging to slow log of 'Thread_id, Schema, Query Cache hit, Rows sent and Rows examined' Added optional logging to slow log, through log_slow_verbosity, of query plan statistics Fixed wrong test of error condition sql/log_slow.h: Defines and variables for log_slow_verbosity and log_slow_filter sql/mysql_priv.h: Include log_slow.h sql/mysqld.cc: Added new user variables log_slow_rate_limit, log_slow_verbosity, log_slow_filter Added log-slow-file as synonym for 'slow-log-file', as most slow-log variables starts with 'log-slow' Added log-slow-time as synonym for long-query-time Added note that one should use log-slow-filter instead of log-slow-admin-statements Updated comment from 'slow_query_log_file' sql/set_var.cc: Added long_slow_time as synonym for long_query_time Added new user variables log_slow_rate_limit, log_slow_verbosity, log_slow_filter dded handling of 'set' variables to set_var.cc.
