When a table status is requested by statement like SHOW TABLE
STATUS and there is another statement (e.g. DELETE) sets
number of records to 0 concurrently, we may get division by
zero error, which crashes a server.

This is fixed by using thread local variable x->records instead
of shared info->state->records when we check if it is zero and
divide by it.


myisam/mi_info.c:
  Information schema does not lock a table when it requests table
  state info. If another thread sets info->state->records to 0
  after we check if it is 0 and before we divide by it we may get
  division by zero error.
  
  Check and divide by local x->records variable instead of shared
  info->state->records.

IGNORE/USE/FORCE INDEX hints were honored when choosing FULLTEXT
index.

With this fix these hints are ignored. For regular indexes we may
perform table scan instead of index lookup when IGNORE INDEX was
specified. We cannot do this for FULLTEXT in NLQ mode.


mysql-test/r/fulltext.result:
  A test case for bug#25951.
mysql-test/t/fulltext.test:
  A test case for bug#25951.
sql/item_func.cc:
  IGNOR/USE/FORCE INDEX hints should not be honored when choosing FULLTEXT
  index.
  
  Use proper bitmap, that is not modified by IGNORE/USE/FORCE INDEX hints.

MERGE engine may return incorrect values when several representations
of equal keys are present in the index. For example "groß" and "gross"
or "gross" and "gross " (trailing space), which are considered equal,
but have different lengths.

The problem was that key length was not recalculated after key lookup.

Only MERGE engine is affected.


myisam/mi_rkey.c:
  info->lastkey gets rewritten by mi_search. Later we recalculate found lastkey
  length. This is done to make sure that mi_rnext_same gets true, found (not
  searched) lastkey length. Searched and found key lengths may be different,
  for example in case searched key is "groß" and found is "gross" or in case
  a key has trailing spaces.
  
  Unfortunately we recalculate found lastkey length only for first
  underlying table. To recalculate found key length for non-first underlying
  table we need to know how much key segments were used to create this key.
  
  When mi_rkey is called for first underlying table of a merge table, store
  offset to last used key segment.
  
  Restore last_used_keyseg variable when mi_rkey is called for non-first
  underlying table.
myisam/myisamdef.h:
  Added last_used_keyseg variable to MI_INFO. It is used by merge engine to calculate
  key length.
myisammrg/myrg_rkey.c:
  Pass last used key segment returned by first table key read to other
  table key reads.

This will hopefully fix events.test failure on vmware-win32, 
where scheduling is very primitive.


mysql-test/t/events_scheduling.test:
  This test case has no races now and can be enabled under valgrind.
sql/event_scheduler.cc:
  Make Event Scheduler thread shutdown more synchronous: report
  successful shutdown only after having removed the scheduler
  thread from the global list of threads.
  This ensures that after the scheduler has been stopped, its

  Make sure that when reading mysql.event the key number matches
  the field number that we're using to read by key.
  Also, print an error in case of a handler error (to not return 
  'Unknown error' when a table is corrupted to the user).

sql/event_data_objects.cc:
  Disable an event if its data in the table is corrupted.
sql/events.cc:

Apparently it's the only platform in pushbuild where we 
compile without openssl.

when there are no up-to-date system tables to support it:
 - initialize the scheduler before reporting "Ready for connections".
   This ensures that warnings, if any, are printed before "Ready for
   connections", and this message is not mangled.
 - do not abort the scheduler if there are no system tables
 - check the tables once at start up, remember the status and disable
   the scheduler if the tables are not up to date.
   If one attempts to use the scheduler with bad tables,
   issue an error message.
 - clean up the behaviour of the module under LOCK TABLES and pre-locking
   mode
 - make sure implicit commit of Events DDL works as expected.
 - add more tests


Collateral clean ups in the events code.

mysql-test/t/events_bugs.test:
  Move the non-concurrent part of test for Bug 16420 to this file.
mysql-test/t/events_restart_phase1.test:
  Rewrite events_restart_* tests to take into account that now
  we check mysql.event table only once, at server startup.
mysql-test/t/events_restart_phase2.test:

sql/event_data_objects.cc:
  Move update_timing_fields functionality to Event_db_repository.
  Make loading of events from a table record more robust to tampering
  with the table - now we do not check mysql.event on every table open.
sql/event_data_objects.h:
  Cleanup.
sql/event_db_repository.cc:
  Now Event_db_repository is responsible for table I/O only.
  All the logic of events DDL is handled outside, in Events class please
  refer to the added test coverage to see how this change affected
  the behavior of Event Scheduler.
  Dependency on sp_head.h and sp.h removed.
  Make this module robust to tweaks with mysql.event table.
  Move check_system_tables from events.cc to this file
sql/event_db_repository.h:
  Cleanup declarations (remove unused ones, change return type to bool
  from int).
sql/event_queue.cc:
  Update to adapt to the new start up scheme of the Event Scheduler.
sql/event_queue.h:
  Cleanup declarations.
sql/event_scheduler.cc:
  Make all the error messages uniform:
  [SEVERITY] Event Scheduler: [user][schema.event] message
  Using append_identifier for error logging was an overkill - we may 
  need it only if the system character set may have NUL (null character)
  as part of a valid identifier, this is currently never the case, 
  whereas additional quoting did not look nice in the log.
sql/event_scheduler.h:
  Cleanup the headers.
sql/events.cc:
  Use a different start up procedure of Event Scheduler:
  - at start up, try to check the system tables first.
  If they are not up-to-date, disable the scheduler.
  - try to load all the active events. In case of a load error, abort
  start up.
  - do not parse an event on start up. Parsing only gives some information
  about event validity, but far not all.
  Consolidate the business logic of Events DDL in this module.
  Now opt_event_scheduler may change after start up and thus is protected
  by LOCK_event_metadata mutex.
sql/events.h:
  Use all-static-data-members approach to implement Singleton pattern.
sql/mysqld.cc:
  New invocation scheme of Events. Move some logic to events.cc.
  Initialize the scheduler before reporting "Ready for connections".
sql/set_var.cc:
  Clean up sys_var_thd_sql_mode::symbolic_mode_representation
  to work with a LEX_STRING.
  Move more logic related to @@events_scheduler global variable to Events
  module.
sql/set_var.h:
  Update declarations.
sql/share/errmsg.txt:
  If someone tampered with mysql.event table after the server has
  started we no longer give him/her a complete report what was actually 
  broken. Do not send the user to look at the error log in such case,
  as there is nothing there (check_table_intact is not executed).
sql/sp_head.cc:
  Update to a new declaration of 
  sys_var_thd_sql_mode::symbolic_mode_representation
sql/sql_db.cc:
  New invocation scheme of Events module.
sql/sql_parse.cc:
  Move more logic to Events module. Make sure that we are consistent
  in the way access rights are checked for Events DDL: always
  after committing the current transaction and checking the system tables.
sql/sql_show.cc:
  Update to the new declarations of 
  sys_var_thd_sql_mode::symbolic_mode_representation
sql/sql_test.cc:
  New invocation scheme of events.
sql/table.cc:
  mysql.event is a system table.
  Update check_table_intact to be concurrent, more verbose, and less smart.
sql/table.h:
  Add a helper method.
mysql-test/r/events_trans.result:
  New BitKeeper file ``mysql-test/r/events_trans.result''
mysql-test/t/events_trans.test:
  New BitKeeper file ``mysql-test/t/events_trans.test'':
  test cases for Event Scheduler that require a transactional
  storage engine.
