key_cmp -> key_cmp_if_same
New records_in_range() interface (similar to read_range()) Macros for faster bitmap handling Simplify read_range() code (#WL1786) New general key_cmp() function to compare keys heap/hp_hash.c: New records_in_range() interface include/heap.h: New records_in_range() interface include/my_base.h: Moved 'key_range' here so that all table handlers can use it include/my_bitmap.h: Make some bitmap functions inline for faster usage in one thread include/myisam.h: New records_in_range() interface include/myisammrg.h: New records_in_range() interface myisam/mi_range.c: New records_in_range() interface myisam/mi_test2.c: New records_in_range() interface myisam/rt_test.c: New records_in_range() interface Indentation fixes myisam/sp_test.c: New records_in_range() interface Indentation fixes myisammrg/myrg_range.c: New records_in_range() interface mysys/my_bitmap.c: Make some bitmap functions inline for faster usage in one thread sql/examples/ha_example.cc: New records_in_range() interface sql/field.cc: Fixed indentation sql/ha_berkeley.cc: New records_in_range() interface sql/ha_berkeley.h: New records_in_range() interface sql/ha_heap.cc: New records_in_range() interface sql/ha_heap.h: New records_in_range() interface sql/ha_innodb.cc: New records_in_range() interface sql/ha_innodb.h: New records_in_range() interface sql/ha_isam.cc: New records_in_range() interface sql/ha_isam.h: New records_in_range() interface sql/ha_myisam.cc: New records_in_range() interface sql/ha_myisam.h: New records_in_range() interface sql/ha_myisammrg.cc: New records_in_range() interface sql/ha_myisammrg.h: New records_in_range() interface sql/ha_ndbcluster.cc: New records_in_range() interface sql/ha_ndbcluster.h: New records_in_range() interface sql/handler.cc: Simplify read_range() interface: - Add 'eq_range' to read_range_first - Remove 'eq_range' parameer from read_range_next() - Trust values from index_next_same() - Simplfy compare_key() by moving key_comparision to key.cc (as this code can be reused from other places) sql/handler.h: Move key_range to my_base.h to be used by external table handlers Simplify read_range() interface New records_in_range() interface sql/key.cc: Rename key_cmp() to key_cmp_if_same() to make it more descriptive Add new key_cmp() function usable from range and handler code. sql/mysql_priv.h: Prototypes for new functions sql/opt_range.cc: New records_in_range() interface Simplify cmp_prev() (We can in 5.0 simplify cmp_next() the same way) sql/opt_range.h: Added key_part_info to QUICK_SELECT to be able to use key_cmp() in get_next() sql/opt_sum.cc: key_cmp -> key_cmp_if_same sql/sql_acl.cc: key_cmp -> key_cmp_if_same sql/sql_select.cc: key_cmp -> key_cmp_if_same
