Subject: bug#58964: 28.2; `file-notify--handle-event` setting callback function to nil
Date: Wed, 02 Nov 2022 08:41:38 -0400 [thread overview]
Message-ID: <m2v8nxzfy5.fsf@umass.edu> (raw)
The following minimal configuration can be used to trigger the bug on my
end, replacing “~/tmp/test.el” with a path to a file of your choice:
(require 'filenotify)
(require 'autorevert)
(require 'subr-x)
(global-auto-revert-mode)
(save-window-excursion
(find-file "~/tmp/test.el"))
Once that’s loaded, calling this:
(file-notify--handle-event (car (hash-table-keys file-notify-descriptors)) '(renamed attribute-changed deleted) (expand-file-name "~/tmp/test.el") nil)
gives me an error
file-notify--call-handler: Symbol’s function definition is void: nil
Here’s the backtrace:
Debugger entered--Lisp error: (void-function nil)
nil((18 attribute-changed "/Users/apc/tmp/test.el"))
file-notify--call-handler(#s(file-notify--watch :directory "/Users/apc/tmp" :filename "test.el" :callback nil) 18 attribute-changed "/Users/apc/tmp/test.el" nil)
file-notify--handle-event(18 (renamed attribute-changed deleted) "/Users/apc/tmp/test.el" nil)
(progn (file-notify--handle-event (car (hash-table-keys file-notify-descriptors)) '(renamed attribute-changed deleted) (expand-file-name "~/tmp/test.el") nil))
eval((progn (file-notify--handle-event (car (hash-table-keys file-notify-descriptors)) '(renamed attribute-changed deleted) (expand-file-name "~/tmp/test.el") nil)) t)
elisp--eval-last-sexp(nil)
eval-last-sexp(nil)
funcall-interactively(eval-last-sexp nil)
call-interactively(eval-last-sexp nil nil)
command-execute(eval-last-sexp)
Unfortunately, I cannot figure out at which step is `nil` being passed as the value of `:callback`.
