From b3aaac8a37c467a1125c794196caa90d0957bdc3 Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Thu, 9 Jan 2020 09:58:48 -0800 Subject: Export of internal Abseil changes -- 9beb68204986a015c9cb065b9fae4f9a8879a788 by Abseil Team : Move Base64EscapeInternal and CalculateBase64EscapedLenInternal to an internal header. PiperOrigin-RevId: 288917378 -- 90acfbe03b3f9f6de3ffa49c39343dfaa2c5d38c by Greg Falcon : Update macos CI script to support the ALTERNATE_OPTIONS environment variable. PiperOrigin-RevId: 288913564 -- f1572e870678cdcda6b48cb39780d1ad984e4c1b by Derek Mauro : Makes absl::NullSafeStringView constexpr Fixes https://github.com/abseil/abseil-cpp/issues/583 PiperOrigin-RevId: 288906940 -- d28a8471e32c10caa64bfffe6d6d4d0a8d144013 by Abseil Team : absl::GetFlag is lock free for small trivially copyable types. PiperOrigin-RevId: 288768172 -- 2643b8ed1a1dc836b38ab9e46538a1af129ffd67 by Gennadiy Rozental : Eliminate call to callback from flag initialization. We do not need to have this invocation inside FlagImpl::Init since SetCallback performs invocation anyways. Calling InitCallback from inside of Init complicates separation of value initialization from data guard initialization, which is about to happen. PiperOrigin-RevId: 288732526 -- 22caa880b7a4cb6da34e16a2e064a473c99e880b by Abseil Team : Fix the documentation on how to create a null string_view. PiperOrigin-RevId: 288727968 -- 10727c5cadc561837141176f4c9b9717cec9233a by Greg Falcon : Change CI scripts for gcc to use the ALTERNATE_OPTIONS file as well. PiperOrigin-RevId: 288718855 -- 5d1e2dd6c7fb12af8aa4337a0f61872f5f0c5992 by Greg Falcon : Add an option for using inline namespaces in Abseil.
