Presumably w32.c should also add support for futimens and utimensat (the POSIX APIs, which Emacs now uses) and it can remove fdutimens (the Gnulib API, which Emacs no longer uses).

* Add 'nofollow' flag to set-file-modes etc.Paul Eggert2020-02-233-0/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This avoids some race conditions (Bug#39683). E.g., if some other program changes a file to a symlink between the time Emacs creates the file and the time it changes the file’s permissions, using the new flag prevents Emacs from inadvertently changing the permissions of a victim in some completely unrelated directory. * admin/merge-gnulib (GNULIB_MODULES): Add fchmodat. * doc/lispref/files.texi (Testing Accessibility, Changing Files): * doc/lispref/os.texi (File Notifications): * etc/NEWS: Adjust documentation accordingly. * lib/chmodat.c, lib/fchmodat.c, lib/lchmod.c, m4/fchmodat.m4: * m4/lchmod.m4: New files, copied from Gnulib. * lib/gnulib.mk.in: Regenerate. * lisp/dired-aux.el (dired-do-chmod): * lisp/doc-view.el (doc-view-make-safe-dir): * lisp/emacs-lisp/autoload.el (autoload--save-buffer): * lisp/emacs-lisp/bytecomp.el (byte-compile-file): * lisp/eshell/em-pred.el (eshell-pred-file-mode): * lisp/files.el (backup-buffer-copy, copy-directory): * lisp/gnus/mail-source.el (mail-source-movemail): * lisp/gnus/mm-decode.el (mm-display-external): * lisp/gnus/nnmail.el (nnmail-write-region): * lisp/net/tramp-adb.el (tramp-adb-handle-file-local-copy) (tramp-adb-handle-write-region): * lisp/net/tramp-sh.el (tramp-do-copy-or-rename-file-directly): * lisp/net/tramp-sudoedit.el (tramp-sudoedit-handle-write-region): * lisp/net/tramp.el (tramp-handle-write-region) (tramp-make-tramp-temp-file): * lisp/server.el (server-ensure-safe-dir): * lisp/url/url-util.el (url-make-private-file): When getting or setting file modes, avoid following symbolic links when the file is not supposed to be a symbolic link. * lisp/doc-view.el (doc-view-make-safe-dir): Omit no-longer-needed separate symlink test. * lisp/gnus/gnus-util.el (gnus-set-file-modes): * lisp/net/tramp.el (tramp-handle-file-modes): * lisp/net/tramp-gvfs.el (tramp-gvfs-handle-set-file-modes): * src/fileio.c (symlink_nofollow_flag): New function.
