From e36603d849bbcd3a2e8eef4896012be4bf6dc2ba Mon Sep 17 00:00:00 2001 From: Jax-YHH Date: Wed, 24 Jul 2024 15:36:31 +0800 Subject: [PATCH] feat:Add support for decimal256 type 1 The logic for detecting overflow during addition and multiplication in decimal.cpp has been revised. 2 The Int128 type has been globally updated across the project. The previously used absl library has been deprecated in favor of proton's wide::Integer. 3 The logic of some unit tests (UT) has been modified. --- timeplus/columns/date.cpp | 2 +- timeplus/columns/decimal.cpp | 107 +++++++++++++++++++++++++++------ timeplus/columns/decimal.h | 6 +- timeplus/columns/factory.cpp | 2 + timeplus/columns/itemview.cpp | 5 +- timeplus/columns/numeric.h | 3 +- timeplus/types/type_parser.cpp | 1 + timeplus/types/types.cpp | 5 ++ timeplus/types/types.h | 6 +- ut/Column_ut.cpp | 2 +- ut/client_ut.cpp | 68 +++++++++++---------- ut/column_array_ut.cpp | 4 +- ut/columns_ut.cpp | 48 ++++++++++----- ut/itemview_ut.cpp | 53 ++++++++-------- ut/value_generators.cpp | 18 +++--- ut/value_generators.h | 2 +- 16 files changed, 216 insertions(+), 116 deletions(-) diff --git a/timeplus/columns/date.cpp b/timeplus/columns/date.cpp index 060c2b7..aa3b45a 100644 --- a/timeplus/columns/date.cpp +++ b/timeplus/columns/date.cpp @@ -310,7 +310,7 @@ void ColumnDateTime64::Reserve(size_t new_cap) void ColumnDateTime64::Append(ColumnRef column) { if (auto col = column->As()) { - data_->Append(col->data_);
