From: "Troy de Freitas" <me <at> ntdef.com> To: bug-gnu-emacs <at> gnu.org Subject: 29.0.50; file-notify-add-watch fails for socket files on MacOS Date: Tue, 11 Jan 2022 10:22:01 -0600
This bug affects MacOS (and most likely FreeBSD and OpenBSD as well).
On MacOS running `file-notify-add-watch' throws an error when attached to a UNIX socket
file but works fine on Linux. To reproduce, using 'emacs -Q', evaluate the following elisp:
(let* ((sock "/tmp/netproc.sock")
(p (make-network-process
:name "test"
:family 'local
:local sock
:server t)))
(unwind-protect
(file-notify-add-watch sock '(change)
(lambda (_) (message (format "%s changed." sock))))
(delete-process p)
(delete-file sock)))
It throws the error:
edebug-signal: File cannot be opened: Operation not supported on
socket, /tmp/netproc.sock
The issue appears to be in the underlying call to `kqueue-add-watch',
which uses `openat()' (by way of `emacs_open()`) to get a
file-descriptor. According to the BSD docs for `openat()', calling
`openat()' on socket files is not supported.
