Keep progress - may not build
Good interface to collect LBIDs and CPInfo's
Write Engine compiles with new interface
New interface breaks things the least way and allows for new features to be added gradually.
Still ironing design - rewriting parts of WE
Keep progress commit
Write Engine compiles, going to test
I could introduce crashes there. Let's see.
Disable logging for tests
Fixing build problems - keep progress commit
Changed related to new interface
Add back accidentally removed m_txnLBIDMap.find
Remove printf/cout; up-to-date comment for AddLBIDtoList
Add "auto" type annotation
Work on PR comments
Descriptive vector emptines check
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.
There are multiple overloaded version of the low level DML write methods to
push down CSC column type. WE needs the type to convert values correctly.
Replaced WE_INT128 with CSC data type that is more informative.
Removed commented and obsolete code.
Replaced switch-case blocks with oneliners.
Fixes the following:
* Generate error if calculateRowId fails
* No data written when first extent is completely full on a write, all
data going to second extent.
* 0 byte valArray malloc
* valArray free() on no malloc
* Column touched but no data written if all data going to second extent
* Wrong colWidth used on second extent calculateRowId
* Out of bounds memory write (crash) when no data for first extent
* Extent not committed if all data going to second extent
HWM for DML and API was being calculated using the first column in a
table instead of the smallest column. This shifts the calculation to the
correct column.
When the API inserts data into ColumnStore which will roll over into a
new extent that data wasn't being put into the new extent and corruption
occured. This patch now tracks the additional data and inserts it into
the new extent. It also makes sure the LBIDs are stored so that they are
correctly committed.
The rowID and therefore HWM for an insert was being calculated based on
the first column. If there are smaller columns in the table these will
insert in the middle of blocks instead of creating new blocks. This means
that we would no longer be crash safe and PrimProc gets very confused until
a cache flush.
We now use the smallest column to calculate the rowID and HWM increment
(as cpimport does).
* TEXT and BLOB now have separate identifiers internally
* TEXT columns are identified as such in system catalog
* cpimport only requires hex input for BLOB, not TEXT
