From: Michael Albinus <michael.albinus <at> gmx.de> To: 41287 <at> debbugs.gnu.org Subject: bug#41287: 28.0.50; Spurious warning "Unused lexical" Date: Fri, 15 May 2020 15:44:05 +0200
I have the following defun in tramp.el (my local repo)
--8<---------------cut here---------------start------------->8---
(defun tramp-get-signal-strings ()
"Strings to return by `process-file' in case of signals."
;; We use key nil for local connection properties.
(with-tramp-connection-property nil "signal-strings"
(let (result)
(if (and (stringp shell-file-name) (executable-find shell-file-name))
(dotimes (i 128 (reverse result))
(push
(if (= i 19) 1 ;; SIGSTOP
(call-process
shell-file-name nil nil nil "-c" (format "kill -%d $$" i)))
result))
(dotimes (i 128 (reverse result))
(push (format "Signal %d" i) result))))))
--8<---------------cut here---------------end--------------->8---
Compiling this, I get
--8<---------------cut here---------------start------------->8---
tramp.el:5065:1: Warning: Unused lexical variable ‘i’
tramp.el:5065:1: Warning: Unused lexical variable ‘i’
--8<---------------cut here---------------end--------------->8---
`i' is used in both `dotimes' loops. What does the compiler tell me?
Best regards, Michael.
