A lot of small fixes and new test cases. client/mysqlbinlog.cc: Cast removed client/mysqltest.cc: Added missing DBUG_RETURN include/my_pthread.h: set_timespec_time_nsec() now only takes one argument mysql-test/t/date_formats.test: Remove --disable_ps_protocl as now also ps supports microseconds mysys/my_uuid.c: Changed to use my_interval_timer() instead of my_getsystime() mysys/waiting_threads.c: Changed to use my_hrtime() sql/field.h: Added bool special_const_compare() for fields that may convert values before compare (like year) sql/field_conv.cc: Added test to get optimal copying of identical temporal values. sql/item.cc: Return that item_int is equal if it's positive, even if unsigned flag is different. Fixed Item_cache_str::save_in_field() to have identical null check as other similar functions Added proper NULL check to Item_cache_int::save_in_field() sql/item_cmpfunc.cc: Don't call convert_constant_item() if there is nothing that is worth converting. Simplified test when years should be converted sql/item_sum.cc: Mark cache values in Item_sum_hybrid as not constants to ensure they are not replaced by other cache values in compare_datetime() sql/item_timefunc.cc: Changed sec_to_time() to take a my_decimal argument to ensure we don't loose any sub seconds. Added Item_temporal_func::get_time() (This simplifies some things) sql/mysql_priv.h: Added Lazy_string_decimal() sql/mysqld.cc: Added my_decimal constants max_seconds_for_time_type, time_second_part_factor sql/table.cc: Changed expr_arena to be of type CONVENTIONAL_EXECUTION to ensure that we don't loose any items that are created by fix_fields() sql/tztime.cc: TIME_to_gmt_sec() now sets *in_dst_time_gap in case of errors This is needed to be able to detect if timestamp is 0 storage/maria/lockman.c: Changed from my_getsystime() to set_timespec_time_nsec() storage/maria/ma_loghandler.c: Changed from my_getsystime() to my_hrtime() storage/maria/ma_recovery.c: Changed from my_getsystime() to mmicrosecond_interval_timer() storage/maria/unittest/trnman-t.c: Changed from my_getsystime() to mmicrosecond_interval_timer() storage/xtradb/handler/ha_innodb.cc: Added support for new time,datetime and timestamp unittest/mysys/thr_template.c: my_getsystime() -> my_interval_timer() unittest/mysys/waiting_threads-t.c: my_getsystime() -> my_interval_timer()
