From 567815df38a2ff54ad7478a90bd75c91e434236a Mon Sep 17 00:00:00 2001 From: makepost Date: Mon, 24 Dec 2018 03:13:16 +0200 Subject: [PATCH] Use st_mtim if st_mtime is macro, fix #1510 In POSIX.1-2008, sys_stat has a st_mtim member and a st_mtime backward compatibility macro. Should help avoid hardcoding platform detection. --- src/disk_interface.cc | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) --- a/src/disk_interface.cc +++ b/src/disk_interface.cc @@ -202,19 +202,13 @@ TimeStamp RealDiskInterface::Stat(const // that it doesn't exist. if (st.st_mtime == 0) return 1; -#if defined(__APPLE__) && !defined(_POSIX_C_SOURCE) +#if defined(_AIX) + return (int64_t)st.st_mtime * 1000000000LL + st.st_mtime_n; +#elif defined(__APPLE__) return ((int64_t)st.st_mtimespec.tv_sec * 1000000000LL + st.st_mtimespec.tv_nsec); -#elif (_POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700 || defined(_BSD_SOURCE) || defined(_SVID_SOURCE) || \ - defined(__BIONIC__) || (defined (__SVR4) && defined (__sun)) || defined(__FreeBSD__)) - // For glibc, see "Timestamp files" in the Notes of http://www.kernel.org/doc/man-pages/online/pages/man2/stat.2.html - // newlib, uClibc and musl follow the kernel (or Cygwin) headers and define the right macro values above. - // For bsd, see https://github.com/freebsd/freebsd/blob/master/sys/sys/stat.h and similar - // For bionic, C and POSIX API is always enabled. - // For solaris, see https://docs.oracle.com/cd/E88353_01/html/E37841/stat-2.html. +#elif defined(st_mtime) // A macro, so we're likely on modern POSIX. return (int64_t)st.st_mtim.tv_sec * 1000000000LL + st.st_mtim.tv_nsec; -#elif defined(_AIX) - return (int64_t)st.st_mtime * 1000000000LL + st.st_mtime_n; #else return (int64_t)st.st_mtime * 1000000000LL + st.st_mtimensec; #endif
