MCOL-4409 This patch combines VDecimal and Decimal and makes
IDB_Decimal an alias for the result class
MCOL-4409 More boilerplate reduction in Func_mod
Removed couple TSInt128::toType() methods
Removed uint128 from joblist/lbidlist.*
Another toString() method for wide-decimal that is EMPTY/NULL aware
Unified decimal processing in WF functions
Fixed a potential issue in EqualCompData::operator() for
wide-decimal processing
Fixed some signedness warnings
For now it consists of only:
using int128_t = __int128;
using uint128_t = unsigned __int128;
All new privitive data types should go into this file in the future.
The else if block in Row::equals() was incorrectly getting triggered
for narrow decimals earlier. We now specifically check if the column
is a wide decimal. Furthermore, we need to dereference the int128_t
pointers for equality comparison.
WF::percentile runtime threw an exception b/c of wrong DT deduced from its argument
Replaced literals with constants
Tought WF_sum_avg::checkSumLimit to use refs instead of values
This commit also adds support in TupleHashJoinStep::forwardCPData,
although we currently do not support wide decimals as join keys.
Row estimation to determine large-side of the join is also updated.
2. Set Decimal precision in SimpleColumn::evaluate().
3. Add support for int128_t in ConstantColumn.
4. Set IDB_Decimal::s128Value in buildDecimalColumn().
5. Use width 16 as first if predicate for branching based on decimal width.
This commit introduces DataConvert UTs.
DataConvert::decimalToString now can negative values.
Next version for Row::toString(), applyMapping UT checks.
Row:equals() is now wide-DECIMAL aware.
Binary NULL magic now consists of a series of BINARYEMPTYROW-s + BINARYNULL
in the end.
ByteStream now has hexbyte alias.
Added ColumnCommand::getEmptyRowValue to support 16 byte EMPTY values.
Replaced BINARYEMPTYROW and BINARYNULL values. We need to have
separate magic values for numeric and non-numeric binary types
b/c numeric cant tolerate losing 0 used for magics previously.
atoi128() now parses minus sign and produces negative values.
RowAggregation::isNull() now uses Row::isNull() for DECIMAL.
TupleAggregateStep class method and buildAggregateColumn() now properly set result data type.
doSum() now handles DECIMAL(38) in approprate manner.
Low-level null related methods for new binary-based datatypes now handles magic values for
binary-based DT.
