Since we now perform type promotion to wide decimals for aggregations
involving numeric fields, we need to check for wide decimal in
in and out ROWs and call the appropriate setter and getter functions.
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.
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.
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.
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:
* Irrelevant where conditions
* Irrelevant const
* A potential infinite loop in treenode
* Bad implicit case fallthroughs
* Explicit markings for required case fallthroughs
* Unused variables
* Unused function
Also disabled some warnings for now which we should fix later.
Rename packages to MariaDB-columnstore-engine, MariaDB-columnstore-libs
and MariaDB-columnstore-platform.
Also add the "columnstore-" prefix the the components so that MariaDB's
packaging system understands then and add a line to include them in
MariaDB's packaging.
In addition
* Fix S3 building for dist source build
* Fix Debian 10 dependency issue
* Fix git handling for dist builds
* Add support for MariaDB's RPM building
* Use MariaDB's PCRE and readline
* Removes a few dead files
* Fix Boost noncopyable includes
Found the following:
* Potential stack explosions with alloca() usage on potentially large
strings
* Memory leaks in WriteEngineServer
* Stack usage out of scope in dataconvert
* A typo in an 'if' statement in dataconvert
I reformulate the messages.
Changed version in preprocessor conditions to avoid compilation
warnings in Debian 9.
Disabled sign-compare check for generated files in DML/DDL.
Fixed pragmas that disables compilation checks.
DDLProc now returns an error if it couldn't cwd.
Use either auto_ptr or unique_ptr depending on GCC version.
