* Int128 support - work in progress
* Work in progress
* Int128 datatype appears to be mostly OK except sort & index
* Fixed divide scaling, added sorting & network (xdr) support
* Binding control, aggregate nodes, cleanup and documentation
* Fixed VS2017 AppVeyor build
* Next attempt to fix vs2017 build
* Next attempt to fix vs2017 build
* Next attempt to fix vs2017 build
* Update MSVC build.
* Set VS architecture correctly
* Fixed a number of issues noticed by Mark
TODO:
- Support regions.
- Reevaluate decision of store date/time components in memory in its own time zone instead of normalized to UTC.
- Fix ISQL's SET TIME command.
- Allow usage of "WITHOUT TIME ZONE" with TIME/TIMESTAMP data types.
- Think about compatibility of CURRENT_TIME/CURRENT_TIMEZONE.
- Support AT { LOCAL | TIME ZONE <zone> } expression.
- Support as needed and fix assertions when altering field types.
- Change conversion to string to put a space before the time zone.
- Big endian version of SKD_time_tz and SKD_timestamp_tz.
* Raise underflow when close to 0 decfloat value casted to double
* High precision NUMERIC datatype based on DECFLOAT
* Fixed bulk insert mode in isql for decfloat values
* Enforce correct decQuad format after arithmetic operations
* Minimum docs for high precision NUMERIC/DECIMAL
* Some fixes of code suggested by Adriano:
- Use "const" keyword for Decimal128 constants declared internally
- Remove unneeded buffer initialization
- Remove unused function makeDecimalFixed()
- Follow firebird naming conventions to make code better readable and avoid possible conflicts with various .h files
- Added forgotten scale for DecimalFixed
2) Applied the same approach to temporary GC records.
3) Refactored the Record class to avoid reallocations, to improve encapsulation and to simplify the code.
4) Slightly refactored UndoItem to isolate its logic from the Record class.
5) Reduced the in-memory size of the undo log.
6) Slightly better alternative to the legacy NULL reporting for outer joins.
7) Minor fixes and adjustments in BufferedStream.
Store ValueExprNodes instead of jrd_nod in the metadata cache.
Make RecordSourceNode child of ExprNode as they share most operations.
Get rid of the JRD visitors in favor of direct calls.
Convert assignments statement lists created inside expressions to separate source and targets ValuesExprNodes.
