Improved speed of thr_alarm from O(N) to O(1). thr_alarm is used to handle timeouts and kill of connections. Fixed compiler warnings. queues.h and queues.c are now based on the UNIREG code and thus made BSD. Fix code to use new queue() interface. This mostly affects how you access elements in the queue. If USE_NET_CLEAR is not set, don't clear connection from unexpected characters. This should give a speed up when doing a lot of fast queries. Fixed some code in ma_ft_boolean_search.c that had not made it from myisam/ft_boolean_search.c include/queues.h: Use UNIREG code base (BSD) Changed init_queue() to take all initialization arguments. New interface to access elements in queue include/thr_alarm.h: Changed to use time_t instead of ulong (portability) Added index_in_queue, to be able to remove random element from queue in O(1) mysys/queues.c: Use UNIREG code base (BSD) init_queue() and reinit_queue() now takes more initialization arguments. (No need for init_queue_ex() anymore) Now one can tell queue_insert() to store in the element a pointer to where element is in queue. This allows one to remove elements from queue in O(1) instead of O(N) mysys/thr_alarm.c: Use new option in queue() to allow fast removal of elements. Do less inside LOCK_alarm mutex. This should give a major speed up of thr_alarm usage when there is many threads sql/create_options.cc: Fixed wrong printf sql/event_queue.cc: Use new queue interface() sql/filesort.cc: Use new queue interface() sql/ha_partition.cc: Use new queue interface() sql/ha_partition.h: Fixed compiler warning sql/item_cmpfunc.cc: Fixed compiler warning sql/item_subselect.cc: Use new queue interface() Removed not used variable sql/net_serv.cc: If USE_NET_CLEAR is not set, don't clear connection from unexpected characters. This should give a speed up when doing a lot of fast queries at the disadvantage that if there is a bug in the client protocol the connection will be dropped instead of being unnoticed. sql/opt_range.cc: Use new queue interface() Fixed compiler warnings sql/uniques.cc: Use new queue interface() storage/maria/ma_ft_boolean_search.c: Copy code from myisam/ft_boolean_search.c Use new queue interface() storage/maria/ma_ft_nlq_search.c: Use new queue interface() storage/maria/ma_sort.c: Use new queue interface() storage/maria/maria_pack.c: Use new queue interface() Use queue_fix() instead of own loop to fix queue. storage/myisam/ft_boolean_search.c: Use new queue interface() storage/myisam/ft_nlq_search.c: Use new queue interface() storage/myisam/mi_test_all.sh: Remove temporary file from last run storage/myisam/myisampack.c: Use new queue interface() Use queue_fix() instead of own loop to fix queue. storage/myisam/sort.c: Use new queue interface() storage/myisammrg/myrg_queue.c: Use new queue interface() storage/myisammrg/myrg_rnext.c: Use new queue interface() storage/myisammrg/myrg_rnext_same.c: Use new queue interface() storage/myisammrg/myrg_rprev.c: Use new queue interface()

- Item_in_subselect::init_left_expr_cache() should not try to guess whether the left expression is accessed "over the grouping operation" (i.e. the subselect is evaluated after the grouping while the left_expr is an Item_ref that wraps an expression from before the grouping). Instead, let new_Cached_item not to try accessing item->real_item() when creating left expr cache.

join cache module. Without these calls SELECTs over tables with virtual columns that used join cache could return wrong results. This could be seen with the test case added into vcol_misc.test

5.3 had handler::index_only_read_time(uint keynr, double records) while 5.2 got: handler::keyread_read_time(uint index, uint ranges, ha_rows rows) which causes floor()'ing of rows parameter, which makes all further costs different.

- fix a bug in LooseScan strategy execution code (exposed by changing costs/QEP) - Do set join_tab->sorted=TRUE for JOIN_TABs that use LooseScan (partitioning handler cares about "sorted" parameter of h->index_init() call)

* remove handler::index_read_last() * create handler::keyread_read_time() (was get_index_only_read_time() in opt_range.cc) * ha_show_status() allows engine's show_status() to fail * remove HTON_FLUSH_AFTER_RENAME * fix key_cmp_if_same() to work for floats and doubles * set table->status in the server, don't force engines to do it * increment status vars in the server, don't force engines to do it mysql-test/r/status_user.result: correct test results - innodb was wrongly counting internal index searches as handler_read_* calls. sql/ha_partition.cc: compensate for handler incrementing status counters - we want to count only calls to underlying engines sql/handler.h: inline methods moved to sql_class.h sql/key.cc: simplify the check sql/opt_range.cc: move get_index_only_read_time to the handler class sql/sp.cc: don't use a key that's stored in the record buffer - the engine can overwrite the buffer with anything, destroying the key sql/sql_class.h: inline handler methods that need to see THD and TABLE definitions sql/sql_select.cc: no ha_index_read_last_map anymore sql/sql_table.cc: remove HTON_FLUSH_AFTER_RENAME sql/table.cc: set HA_CAN_MEMCMP as appropriate sql/tztime.cc: don't use a key that's stored in the record buffer - the engine can overwrite the buffer with anything, destroying the key storage/myisam/ha_myisam.cc: engines don't need to update table->status or use ha_statistic_increment anymore storage/myisam/ha_myisam.h: index_read_last_map is no more

The statistics after a sequence of inserts/deletes are updated asynchronously in PBXT, causing unpredictable test results. Fix by running the test on a fresh copy of the table with no deletes performed, to get stable results.

1. fix broken change user handling (no restart should happen in the normal case) 2. add assert to guarantee that we never send a request to change to the same plugin 3. "fix" plugin string as sent by the client to be able to compare native plugins by pointers 4. more complete MYSQL initialization in the embedded case 5. change_user.test updated to handle -with-embedded-privilege-control builds
