unarchive 515731
found 515731 coreutils/7.5-4
retitle 515731 does not fallback utimensat() when cp'ing symlinks
thanks
On an up-to-date sid chroot, running on a etch system (yes, I should
upgrade, I know):
# cp -dp /lib/libc.so.6 /root/
cp: preserving times for `/root/libc.so.6': Function not implemented
relevant strace excerpt:
readlink("/lib/libc.so.6", "libc-2.9.so", 12) = 11
symlink("libc-2.9.so", "/root/libc.so.6") = 0
lchown32("/root/libc.so.6", 0, 0) = 0
utimensat(AT_FDCWD, "/root/libc.so.6", {{1252628891, 0}, {1252285776,
0}}, AT_SYMLINK_NOFOLLOW) = -1 ENOSYS (Function not implemented)
It seems to only happen on symlinks; the same for cp -dp /bin/cp /root:
read(3, "", 32768) = 0
utimensat(4, NULL, {{1252628991, 0}, {1252458064, 0}}, 0) = -1 ENOSYS
(Function not implemented)
utimensat(4, NULL, {{1252628991, 0}, {1252458064, 0}}, 0) = -1 ENOSYS
(Function not implemented)
utimes("/proc/self/fd/4", {{1252628991, 0}, {1252458064, 0}}) = 0
(and obviously not failing).
Thanks,
Faidon
