4e8239e098 Merge branch 'master' into DateTime64_extended_range 2021-03-03 23:43:20 +03:00
Vasily Nemkov
2d03d330bc Extended range of DateTime64 to years 1925 - 2238 
The Year 1925 is a starting point because most of the timezones
switched to saner (mostly 15-minutes based) offsets somewhere
during 1924 or before. And that significantly simplifies implementation.

2238 is to simplify arithmetics for sanitizing LUT index access;
there are less than 0x1ffff days from 1925.

* Extended DateLUTImpl internal LUT to 0x1ffff items, some of which
  represent negative (pre-1970) time values.
  As a collateral benefit, Date now correctly supports dates up to 2149
  (instead of 2106).
* Added a new strong typedef ExtendedDayNum, which represents dates
  pre-1970 and post 2149.
* Functions that used to return DayNum now return ExtendedDayNum.
* Refactored DateLUTImpl to untie DayNum from the dual role of being
  a value and an index (due to negative time). Index is now a different
  type LUTIndex with explicit conversion functions from DatNum, time_t,
  and ExtendedDayNum.
* Updated DateLUTImpl to properly support values close to epoch start
  (1970-01-01 00:00), including negative ones.
* Reduced resolution of DateLUTImpl::Values::time_at_offset_change
  to multiple of 15-minutes to allow storing 64-bits of time_t in
  DateLUTImpl::Value while keeping same size.
* Minor performance updates to DateLUTImpl when building month LUT
  by skipping non-start-of-month days.
* Fixed extractTimeZoneFromFunctionArguments to work correctly
  with DateTime64.
* New unit-tests and stateless integration tests for both DateTime
  and DateTime64.

c4b5eed4ff Fix DateTime64 initialization (to match DateTime behaviour) 
There was no specializations for toDateTime64(<numeric>), and because of
this default decimal conversion was used, however this is not enough for
DateTime/DateTime64 types, since the date may overflow and the proper
check is required (like DateTime has), and this what UBsan found [1]:

4713b59159 Fix CAST(Nullable(String), Enum()) 
The wrapper that is returned from createStringToEnumWrapper() does not
have access to the ColumnNullable (i.e. original column), because it is
converted to nested type in the prepareRemoveNullable().

So add original ColumnNullable into the block in prepareRemoveNullable()
if source type is Nullable and pass this flag to the
createStringToEnumWrapper() to make it know about that fact that last
column in the block is the original ColumnNullable in this case.

And this one looks most sane.
