@defopt remote-file-name-inhibit-cache
Whether to use the remote file-name cache for read access.
File attributes of remote files are cached for better performance. If
they are changed out of Emacs' control, the cached values become
invalid, and must be reread.
When set to @code{nil}, cached values are always used. This shall be
set with care. When set to @code{t}, cached values are never used.
ALthough this is the safest value, it could result in performance
A compromise is to set it to a positive number. This means that
cached values are used for that amount of seconds since they were
In case a remote file is checked regularly, it might be reasonable to
let-bind this variable to a value less then the time period between
two checks. Example:
(defun display-time-file-nonempty-p (file)
(let ((remote-file-name-inhibit-cache (- display-time-interval 5)))
(and (file-exists-p file)
(< 0 (nth 7 (file-attributes (file-chase-links file)))))))
