SHOW STATUS are not anymore put in slow query log because of no index usage.
Implemntation done by removing orig_sql_command and moving logic of SHOW STATUS to mysql_excute_command()
This simplifies code and allows us to remove some if statements all over the code.
Upgraded uc_update_queries[] to sql_command_flags and added more bitmaps to better categorize commands.
This allowed some overall simplifaction when testing sql_command.
Fixes bugs:
Bug#10210: running SHOW STATUS increments counters it shouldn't
Bug#19764: SHOW commands end up in the slow log as table scans
mysql-test/r/grant_cache.result:
Fixed results after SHOW STATUS doesn't anymore affect status variables
mysql-test/r/information_schema.result:
Added extra test to cover more code
mysql-test/r/query_cache.result:
Remove resuts from previous tests
mysql-test/r/status.result:
Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables.
(Bug#10210)
mysql-test/r/temp_table.result:
Fixed results after SHOW STATUS doesn't anymore affect status variables
mysql-test/r/union.result:
Fixed results after SHOW STATUS is not logged to slow query log
(Bug#19764)
mysql-test/t/events_microsec.test:
Disable warnings at init
mysql-test/t/information_schema.test:
Added extra test to cover more code
mysql-test/t/query_cache.test:
Remove resuts from previous tests
mysql-test/t/status.test:
Added more tests for testing of last_query_cost and how SHOW STATUS affects status variables.
(Bug #10210)
sql/mysql_priv.h:
Added 'sql_command_flags'
sql/sql_class.cc:
New function add_diff_to_status(), used to update global status variables when using SHOW STATUS
sql/sql_class.h:
New function 'fill_information_schema_tables()'
(One could not anymore use fill_derived_tables() for this as only_view_structures() is not relevant for information schema tables)
Added defines for bit flags in sql_command_flags[]
sql/sql_lex.cc:
Remove orig_sql_command
sql/sql_lex.h:
Remove orig_sql_command
sql/sql_parse.cc:
Rename uc_update_queries -> sql_command_flags.
Enhanced 'sql_command_flags' to better classify SQL commands
uc_update_queries[] != 0 is changed to (sql_command_flags[] & CF_CHANGES_DATA)
lex->orig_sql_command == SQLCOM_END is changed to (sql_command_flags[lex->sql_command] & CF_STATUS_COMMAND) == 0)
Simplify incrementing of thd->status_var.com_stat[] as we don't have to do special handling for SHOW commands.
Split SQLCOM_SELECT handling in mysql_execute_command() to a separate function.
Added special handling of SHOW STATUS commands in mysql_execute_command() and call common SQLCOM_SELECT handling.
These changes allows us to easily fix that we save and restore status variables during execution of a SHOW STATUS command.
Don't log SHOW STATUS commands to slow query log.
This fixes Bug#10210 and Bug#19764 without adding additional 'if' code.
(The new code is faster than the original as we now have fewer if's than before)
sql/sql_prepare.cc:
Clean up prepare-check handling of SQLCOM commands by using sql_command_flags[]
This simplifes code and ensures that code works even if someone forgets to put a new status commands into the switch statement.
sql/sql_select.cc:
Remove special handling of SHOW STATUS.
(This is now done in SQLCOM_SHOW_STATUS part in mysql_execute_command())
sql/sql_show.cc:
Remove orig_sql_command
Only change sql_command during 'open_normal_and_derived_tables()' (for views) and not for the full duration of generating data.
Changed 'show status' to use thd->initial_status_var to ensure that the current statement is not affecting the to-be-used values.
Use thd->fill_information_schema_tables() instead of 'thd->fill_derived_tables()' as the later wrongly checks the value of sql_command.
sql/sql_yacc.yy:
Remove usage of orig_sql_command.
One side effect of this is that we need to test for cursors if the current command is a SELECT or a SHOW command.

resulted in a wrong error message.
The nest_level counter indicates the depth of nesting for a subselect. It is
needed to properly resolve aggregate functions in nested subselects. Obviously
it shouldn't be incremented for UNION parts because they have the same level of
nesting. This counter was incremented by 1 in the mysql_new_select() function
for any new select and wasn't decremented for UNION parts. This resulted in
wrongly reported error messages.
Now the nest_level counter is decremented by 1 for any union part.
