- fix a bug introduced with last commit ALTER EVENT a RENAME TO b; failed
- misc


sql/event.cc:
  - rename evex_db_find_routine_aux() to evex_db_find_event_aux() (better name)
  - change parameter order of db_update_event()
  - last bits to handle errors as close as possible to the place they occur
  - fix a bug introduced with last commit: first check for overwriting and event and then
    check whether the original one exists
sql/event.h:
  add a new error code returned by event_timed::compile() in case of 
  error
sql/event_priv.h:
  rename
sql/event_timed.cc:
  - function rename
  - add a bit of doc
sql/share/errmsg.txt:
  - extend an error message so it's more informative
  - add a new error message
sql/sql_parse.cc:
  refactor the cases for CREATE/ALTER/DROP event so use as much common
  code as possible. last bits of error checking unneeded in sql_parse.cc
  thrwon out.

(strip m_ as prefix from member variables' names)


sql/event.cc:
  - change copyright years
  - remove m_ prefix from member variables (I liked m_)
  - reorder parameter in evex_update_event()
sql/event.h:
  - change copyright years
  - remove m_ prefix from member variables
  - declare some member variables as private (were public)
  - delete 0 is valid in C++ therefore don't embrace with if()
sql/event_executor.cc:
  - executor => scheduler in messages
  - fix a bug introduced in last commit -> typo in a mutex name
  - remove m_ prefix from member variables
sql/event_priv.h:
  - change copyright years
sql/event_timed.cc:
  - change copyright years
  - strip m_ as prefix from member variables' names
sql/sql_parse.cc:
  - strip m_ as prefix from member variables' names
sql/sql_yacc.yy:
  - strip m_ as prefix from member variables names

sql/event.cc:
  - fix TODO (remove things already done)
  - check the length of the event's name and body during creation
    and report an error if longer than what can be fit into 
    mysql.event (nothing like non-strict mode here)
  - report to sql_parse.cc and error when open table failed, otherwise send_ok()
    was being called and the error have become an warning.
  - update function documentation a bit
  - evex_db_find_routine_aux returns 0 and not EVEX_OK
sql/event_executor.cc:
  - CS changes to definitions of the main and worker thread routines
  - reorder code a bit to prevent crashes because of reading of
    already freed data -> first wait all events to finish their work,
    namely all worker threads to finish, and then destroy in-memory
    structures
  - more error checking and error reporting at the place of failure.
sql/event_priv.h:
  code simplifying macro
sql/event_timed.cc:
  CS cosmetics

sql/event.cc:
  -my_error() as close as possible to the place where the error
   occurs.
  -a thought how to replicate events
  -use close_thread_tables() in some cases and for others rely on
   this call being done in sql_parse.cc::do_command()
sql/event.h:
  remove redundant defines
sql/event_executor.cc:
  - reenable the compilation again
  - don't backup the open_tables_state, it's not needed
sql/event_timed.cc:
  - inline a bit
  - comment added
sql/mysqld.cc:
  - start mysqld with --event-scheduler=0 by default
sql/share/errmsg.txt:
  3 new messages
sql/sql_parse.cc:
  remove now obsolete error checking - the errors are reported
  as closer as possible to the place where they are detected
sql/sql_yacc.yy:
  add WARNING message. fix a bug that was corrupting 
  thd->client_capabilites ->
  select count(*) from mysql.event
  was reporting : "Unknown table test.event"!!!
  Using temporal variable is nice but IMO quite error-prone.

sql/sp_head.cc:
  revert

make more independent of SP


sql/event.cc:
  use own routine - export it
sql/event_priv.h:
  export these two
sql/event_timed.cc:
  use own routine, don't rely on SP
sql/sp.cc:
  revert changes to SP
sql/sp.h:
  revert changes to SP
sql/sql_show.cc:
  rever changes to SP

updated sources


sql/event.cc:
  update
  put some error calls to the places they occur
sql/event.h:
  - change the default (does not work in STRICT mode)
sql/event_executor.cc:
  move mutex initialization to evex_init_mutexes so init_events() can be reused when the
  main thread does not work and set global event_scheduler=1; (this will start the thread)
  The main thread is now visible with show processlist and can be killed.
sql/event_priv.h:
  don't use anymore SP for opening table
sql/event_timed.cc:
  don't use anymore SP routines for opening mysql.event
sql/mysqld.cc:
  shutdown_events() should be maximal at the end of the server because
  it destroys mutexes of EVEX. The call should not be in the main thread.
sql/set_var.cc:
  make sys_var_event_executor subclass sys_var_bool_ptr
  to overload ::update() method - needed to start a
  killed (non-running) evex main thread
sql/set_var.h:
  declare class sys_var_event_executor
sql/share/errmsg.txt:
  2 new messages

- split into several files
- forbid parallel execution (before analyse is done how to make it possible)
  because the same sp_head instance cannot be executed in parallel
- added GPL headers
- changed EVENT_ACL to be per DB variable
- fixed minor problems


mysql-test/lib/init_db.sql:
  WL#1034 updated
  - add Event_priv to mysql.user (update test)
  - add updated mysql.event table struct
scripts/mysql_fix_privilege_tables.sql:
  WL#1034 updated
  add updated mysql.event structure
sql/Makefile.am:
  split event.cc into
  - event.cc (create/alter/drop)
  - event_executor.cc (main and worker threads)
  - event_timed.cc (class event_timed)
  - event_priv.h (some definitions used internally by the module)
sql/event.cc:
  - added GPL header
  - split into few files
  - fixed some issues after code review
  - now using SP routines for opening/traversing/closing tables
    (will be reverted)
sql/event.h:
  - add GPL header
  - remove two methods - inline them in sql_yacc.yy 
  - don't use absolute values for EVEX_ defines but the SP_ equivalents (have to move 100% to SP_
    defines and as later step to not transfer messages upwards in the stack but
    report them at the place they occur)
  - updated reference table definition
  - move default mem_root param from event.cc to the header
sql/mysqld.cc:
  WL#1034
  rename --event-executor to --event-scheduler
  executor sounds a bit scary :)
sql/set_var.cc:
  rename internal variable name from event_executor to event_scheduler
  (ppl won't be scarried anymore :)
sql/share/errmsg.txt:
  omit one %s - not needed
sql/sp_head.cc:
  disable this DBUG_PRINT for a bit. m_next_cached_sp is 0x0 and I get crash here...
sql/sp_head.h:
  remove m_old_cmq, a temporal variable is used in sql_yacc.yy (Serg's idea)
  to keep the previous state.
  $<ulong_val>$ =  ....
  
  YYTHD->client_capabilites != $<ulong_val>4;
  
  (the same is done also for class event_timed)
sql/sql_acl.cc:
  handle pre-5.1.4 table and give the user EVENT_ACL if he had CREATE_ACL
sql/sql_acl.h:
  fix the bitmask
sql/sql_parse.cc:
  - move from EVENT_ACL being global to EVENT_ACL being per DB like
    CREATE_PROC_ACL
  - lex->m_qname dropped, because not needed, fix code therefore
  - add comment that SHOW CREATE EVENT has to be implemented
sql/sql_yacc.yy:
  - use temporal variable of Bison to store a short lived value
  - fix indentation
  - inline 2 class event_timed methods in the parser
sql/tztime.h:
  be more expressive - it's already extern

BUILD/SETUP.sh:
  for now no optimizations in debug build - get rid of "value optimized out"

The previous variant where it was a specific ha_partition method
only worked for the partition handler. It was unfortunately called also
for the NDB handler and in this case it called a random method in the
NDB handler with random input.


sql/ha_ndbcluster.cc:
  Moved initialisation of some handler variables to
  set_part_info method called earlly in the open process
sql/ha_ndbcluster.h:

Its funny, I am reading through the forums and someone asks "Can I please have a REPLACE INTO, instead an INSERT INTO?" and I remember how often I have used a sed script to modify MySQL dumps to have exactly that.
So, use --replace and instead of getting INSERT INTO you will INSTEAD get REPLACE INTO. Buyer beward, REPLACE is a MySQL SQL, so you will not end up with a dump that can be used for other databases.

Though I hear you could just use a sed line to modify it back :)


client/client_priv.h:
  New option for --replace
client/mysqldump.c:
  Added option for REPLACE INTO instead of INSERT INTO
mysql-test/r/mysqldump.result:
