and collateral changes. * introduce my_hrtime_t, my_timediff_t, and conversion macros * inroduce TIME_RESULT, but it can only be returned from Item::cmp_type(), never from Item::result_type() * pack_time/unpack_time function for "packed" representation of MYSQL_TIME in a longlong that can be compared * ADDTIME()/SUBTIME()/+- INTERVAL now work with TIME values * numbers aren't quoted in EXPLAIN EXTENDED * new column I_S.COLUMNS.DATETIME_PRECISION * date/time values are compares to anything as date/time, not as strings or numbers. * old timestamp(X) is no longer supported * MYSQL_TIME to string conversion functions take precision as an argument * unified the warnings from Field_timestamp/datetime/time/date/newdate store methods * Field_timestamp_hires, Field_datetime_hires, Field_time_hires * Field_temporal * Lazy_string class to pass a value (string, number, time) polymorphically down the stack * make_truncated_value_warning and Field::set_datetime_warning use Lazy_string as an argument, removed char*/int/double variants * removed Field::can_be_compared_as_longlong(). Use Field::cmp_type() == INT_RESULT instead * introduced Item::cmp_result() instead of Item::is_datetime() and Item::result_as_longlong() * in many cases date/time types are treated like other types, not as special cases * greatly simplified Arg_comparator (regarding date/time/year code) * SEC_TO_TIME is real function, not integer. * microsecond precision in NOW, CURTIME, etc * Item_temporal. All items derived from it only provide get_date, but no val* methods * replication of NOW(6) * Protocol::store(time) now takes the precision as an argument * @@TIMESTAMP is a double client/mysqlbinlog.cc: remove unneded casts include/my_sys.h: introduce my_hrtime_t, my_timediff_t, and conversion macros include/my_time.h: pack_time/unpack_time, etc. convenience functions to work with MYSQL_TIME::second_part libmysql/libmysql.c: str_to_time() is gone. str_to_datetime() does it now. my_TIME_to_str() takes the precision as an argument mysql-test/include/ps_conv.inc: time is not equal to datetime anymore mysql-test/r/distinct.result: a test for an old MySQL bug mysql-test/r/explain.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/func_default.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/func_sapdb.result: when decimals=NOT_FIXED_DEC it means "not fixed" indeed mysql-test/r/func_test.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/func_time.result: ADDTIME()/SUBTIME()/+- INTERVAL now work with TIME values mysql-test/r/having.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/information_schema.result: new column I_S.COLUMNS.DATETIME_PRECISION mysql-test/r/join_outer.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/metadata.result: TIMESTAMP no longer has zerofill flag mysql-test/r/range.result: invalid datetime is not compared with as a string mysql-test/r/select.result: NO_ZERO_IN_DATE, etc only affect storage - according to the manual numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/subselect.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/sysdate_is_now.result: when decimals=NOT_FIXED_DEC it means "not fixed" indeed mysql-test/r/type_blob.result: TIMESTAMP(N) is not deprecated mysql-test/r/type_timestamp.result: old TIMESTAMP(X) semantics is not supported anymore mysql-test/r/union.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/r/varbinary.result: numbers aren't quoted in EXPLAIN EXTENDED mysql-test/t/distinct.test: test for an old MySQL bug mysql-test/t/func_time.test: +- INTERVAL now works with TIME values mysql-test/t/select.test: typo mysql-test/t/subselect.test: only one error per statement, please mysql-test/t/system_mysql_db_fix40123.test: old timestamp(X) is no longer supported mysql-test/t/system_mysql_db_fix50030.test: old timestamp(X) is no longer supported mysql-test/t/system_mysql_db_fix50117.test: old timestamp(X) is no longer supported mysql-test/t/type_blob.test: old timestamp(X) is no longer supported mysql-test/t/type_timestamp.test: old timestamp(X) is no longer supported mysys/my_getsystime.c: functions to get the time with microsecond precision mysys/my_init.c: move the my_getsystime.c initialization code to my_getsystime.c mysys/my_static.c: no need to make these variables extern mysys/my_static.h: no need to make these variables extern scripts/mysql_system_tables.sql: old timestamp(X) is no longer supported scripts/mysql_system_tables_fix.sql: old timestamp(X) is no longer supported scripts/mysqlhotcopy.sh: old timestamp(X) is no longer supported sql-common/my_time.c: * call str_to_time from str_to_datetime, as appropriate * date/time to string conversions take precision as an argument * number_to_time() * TIME_to_double() * pack_time() and unpack_time() sql/event_data_objects.cc: cast is not needed my_datetime_to_str() takes precision as an argument sql/event_db_repository.cc: avoid dangerous downcast (because the pointer is not always Field_timestamp, see events_1.test) sql/event_queue.cc: avoid silly double-work for cond_wait (having an endpoint of wait, subtract the current time to get the timeout, and use set_timespec() macro to fill in struct timespec, by adding the current time to the timeout) sql/field.cc: * remove virtual Field::get_time(), everyone should use only Field::get_date() * remove lots of #ifdef WORDS_BIGENDIAN * unified the warnings from Field_timestamp/datetime/time/date/newdate store methods * Field_timestamp_hires, Field_datetime_hires, Field_time_hires * Field_temporal * make_truncated_value_warning and Field::set_datetime_warning use Lazy_string as an argument, removed char*/int/double variants sql/field.h: * remove virtual Field::get_time(), everyone should use only Field::get_date() * remove lots of #ifdef WORDS_BIGENDIAN * unified the warnings from Field_timestamp/datetime/time/date/newdate store methods * Field_timestamp_hires, Field_datetime_hires, Field_time_hires * Field_temporal * make_truncated_value_warning and Field::set_datetime_warning use Lazy_string as an argument, removed char*/int/double variants * removed Field::can_be_compared_as_longlong().
