From a06c4a1d9093137b7217a5aaba8920d62e835dc0 Mon Sep 17 00:00:00 2001 From: Abseil Team Date: Thu, 15 Nov 2018 11:55:00 -0800 Subject: Export of internal Abseil changes. -- 5f1ab09522226336830d9ea6ef7276d37f536ac5 by Abseil Team : Clarify the documentation of ABSL_MUST_USE_RESULT. PiperOrigin-RevId: 221663609 -- af4c8359a20d56369fd1dce318220cf3be03ca66 by Greg Falcon : Internal change PiperOrigin-RevId: 221538448 -- 487cd09bd1942bf607080deeae38fee6ce66f294 by Eric Fiselier : Work around emscripten bugs and missing features in absl/time:time_test. The emscripten toolchain has a couple of issues that cause time_test to fail. Specifically: 1) emscripten doesn't support signals. 2) The javascript implementation of strftime/strptime use different expansions of '%c' that mean it doesn't round-trip. PiperOrigin-RevId: 221523701 -- 5823652e6a200b97b07334bc47128dfac40e20fc by Xiaoyi Zhang : Fix MSVC compiler warning by explicitly casting to char. Currently our MSVC build breaks with the following error: raw_hash_set.h(406): warning C4309: 'argument': truncation of constant value PiperOrigin-RevId: 221492585 -- c5806358320711a5efbe5c523df13e14ab53a17d by Greg Falcon : Replace calls to getpagesize() with the more portable sysconf(_SC_PAGESIZE); the latter is in POSIX 1.0 and is called out in the Linux `getpagesize` man page as a more portable spelling. PiperOrigin-RevId: 221492471 -- 19ffe82851072229bb7ce73f754ffe4c18e8c575 by Abseil Team : Fix -Wundef error in absl/hash/internal/hash.h.
