WL 2059 Engine-specific status variables framework and WL 1922
InnoDB status variables
innobase/buf/buf0buf.c:
Added function to get the number of latched pages
innobase/buf/buf0flu.c:
Added support for dblwr_pages_written, dblwr_writes and
buffer_pool_pages_flushed status variables
innobase/buf/buf0lru.c:
Added support for _buffer_pool_wait_free status variable
innobase/buf/buf0rea.c:
Added support for buffer_pool_read_ahead_rnd, buffer_pool_read_ahead_seq
and srv_buf_pool_reads status variables
innobase/fil/fil0fil.c:
Added support for os_log_fsyncs, data_read, and data_written
innobase/include/buf0buf.h:
Functions and variables needed for new status variables declared
innobase/include/buf0flu.ic:
Added support for buffer_pool_write_requests status variable
innobase/include/fil0fil.h:
Variable declared
innobase/include/os0file.h:
Declared several variabled
innobase/include/srv0srv.h:
Declared all new variables needed for InnoDB status variables
innobase/log/log0log.c:
Added support for various log-related status variables
innobase/os/os0file.c:
Added support for pending_writes, pending_reads status variables
innobase/srv/srv0srv.c:
Added internal counters and function to accumulate information for
InnoDB status variables
mysql-test/r/innodb.result:
result fot the test
mysql-test/t/innodb.test:
We have tests only for few variables, as we cannot predict value for
most of the added variables. It depends on the system load, OS, HDD
e.t.c Thus, we cannot test them with mysql-test.
sql/ha_innodb.cc:
Added an array for InnoDB status variables. This is part of the
WL2059 Engine-specific status variables framework
sql/ha_innodb.h:
Declared status variables array and the function to refresh statistics
sql/handler.cc:
Added function to get statistics
sql/handler.h:
Declared function to update handlers statistics
sql/mysql_priv.h:
declared opt_innodb to see it from handlers
sql/mysqld.cc:
Don't include Innodb_* status variables into "show status" if we
are compiling without InnoDB
sql/sql_show.cc:
mysqld_show modified and split into two parts to support enclosed
arrays in the show_var_st structure. This is a part of
WL2059 Engine-specific status variables framework.
sql/structs.h:
Added new value to mark enclosed array in the status variables array
