Cut number 6. Move code from sql_show.cc to event_db_repository.cc
that more belongs to the latter.
sql/event_db_repository.cc:
move code that works with mysql.event from sql_show.cc to
event_db_repository.cc . Route through Event_db_repository's interface
which is proxied by class Events. The code relies on a function from
sql_show.cc which does the actual storage in the schema table. I think
it's better to leave the function there because the structure of
I_S.EVENTS is defined in sql_show.cc
sql/event_db_repository.h:
I_S / SHOW EVENTS handling hooks
sql/event_scheduler.cc:
use the pointer to db_repository which Event_scheduler already has
sql/events.cc:
Put a comment to get_instance
sql/events.h:
callback for I_S (sql_show.cc)
sql/sql_show.cc:
move code that belongs more to Event_db_repository than to here.
Use a callback of class Events. Only 1 function is left here, because
it copies data into the actual rows of I_S.EVENTS and belongs to this file.
sql/sql_show.h:
export this function will be called from event_db_repository.cc
5th cut, moved DB related code to Event_db_repository and
updated accordingly the remanining code.
Moved change/restore_security_context() to class THD
Removed events_priv.h
Next step is to reorganize create/update_event() and parsing for them.
But probably some other refactoring could be done in the meanwhile.
The changes so far pass the test suite.

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.
sql/structs.h:
Updated comment

The intermediate (not temporary) files of the new table
during ALTER TABLE was visible for SHOW TABLES. These
intermediate files are copies of the original table with
the changes done by ALTER TABLE. After all the data is
copied over from the original table, these files are renamed
to the original tables file names. So they are not temporary
files. They persist after ALTER TABLE, but just with another
name.
Normal GRANT checking takes place for the intermediate table.
Everyone who can see the original table (and hence the final
table) can also see the intermediate table. But noone else.
In 5.0 the intermediate files are invisible for SHOW TABLES
because all file names beginning with "#sql" were suppressed.
In 5.1 temporary files are created in TMPDIR, so that they
don't appear in the database directories. Also in 5.1 a
translation between table names and file names is done. The
tmp_file_prefix on file level is now "@0023sql".
The suppression of files starting with tmp_file_prefix is
still in place, but still only files beginning with "#sql"
were suppressed.
I do now translate tmp_file_prefix from table name to file
name before comparing it with the files in a directory.
This suppresses the intermediate files again.
No test case. The test case looks so that a reasonable big
table is altered while a second thread runs SHOW TABLES.
This in itself would be possible to do, but on slow machines
it would add too much time to the test suite, while on fast
machines the ALTER TABLE might have finished before SHOW
TABLES looks at the directory. Even if there might be a good
balance for todays machines, one day the test would become
void as the intermediate table would not be seen even with
the bug in place. I added a test script to the bug report.
It can easily be changed so that it uses a table size that
is appropriate for the test machine.
