1From 15f51edf989cc47588c3d8635a62c255cdeb0072 Mon Sep 17 00:00:00 2001 2From: Daniel Cheng <dcheng@chromium.org> 3Date: Wed, 6 Oct 2021 03:23:23 -0700 4Subject: [PATCH] Turn on hardened mode and alias absl types to STL types.. 5 6The absl implementations contain various hardening checks where the 7standard is UB. At the time, libc++ lacked corresponding hardening 8checks, so we forced the use of absl types. As of 9https://crbug.com/1335422, this is no longer true. Switching so the STL 10versions of optional and variant is tracked by https://crbug.com/1373619 and 11https://crbug.com/1373620, respectively. 12--- 13 third_party/abseil-cpp/absl/base/options.h | 10 +++++----- 14 1 file changed, 5 insertions(+), 5 deletions(-) 15 16diff --git a/third_party/abseil-cpp/absl/base/options.h b/third_party/abseil-cpp/absl/base/options.h 17index 230bf1eecc4a4..1641271cd3ff9 100644 18--- a/third_party/abseil-cpp/absl/base/options.h 19+++ b/third_party/abseil-cpp/absl/base/options.h 20@@ -127,7 +127,7 @@ 21 // absl::optional is a typedef of std::optional, use the feature macro 22 // ABSL_USES_STD_OPTIONAL. 23 24-#define ABSL_OPTION_USE_STD_OPTIONAL 2 25+#define ABSL_OPTION_USE_STD_OPTIONAL 0 26 27 28 // ABSL_OPTION_USE_STD_STRING_VIEW 29@@ -180,7 +180,7 @@ 30 // absl::variant is a typedef of std::variant, use the feature macro 31 // ABSL_USES_STD_VARIANT. 32 33-#define ABSL_OPTION_USE_STD_VARIANT 2 34+#define ABSL_OPTION_USE_STD_VARIANT 0 35 36 37 // ABSL_OPTION_USE_INLINE_NAMESPACE 38@@ -233,6 +233,6 @@ 39 // checks enabled by this option may abort the program in a different way and 40 // log additional information when `NDEBUG` is not defined. 41 42-#define ABSL_OPTION_HARDENED 0 43+#define ABSL_OPTION_HARDENED 1 44 45 #endif // ABSL_BASE_OPTIONS_H_ 46-- 472.33.0.882.g93a45727a2-goog 48 49
