Subject: bug#66570: 29.1; Regression when printing option set with value of wrong type
Date: Sun, 15 Oct 2023 21:25:00 +0000 [thread overview]
Message-ID: <SJ0PR10MB54881A472046910981F658D6F3D0A@SJ0PR10MB5488.namprd10.prod.outlook.com> (raw)
emacs -Q
Evaluate (customize-set-variable 'fill-column nil).
No message or error about improver value (just as in previous releases).
C-h v fill-column
An error is raised, but the *Compile-Log* message doesn't say what
function raised the error:
z:/path/to/Emacs-29.1.2/share/emacs/29.1/lisp/emacs-lisp/cl-print.elc:
Error: Wrong type argument: number-or-marker-p, nil
And why does is the error message shown in that buffer?
C-h v fill-column ; Repeat it.
Another error is raised, producing this incomprehensible error msg (this
time it is not shown in *Compile-Log*):
Symbol's function definition is void: t
What function is void, `t'?
Buffer *Messages* shows this:
cl--generic-make-next-function: Symbol's function definition is void: t
In previous releases there is no such problem. The improper value is
just shown in buffer *Help*.
[Arguably, options defined in C should maybe have a non-nil property
`custom-set', with the proper :set function, so that using
`customize-set-variable' raises an error when setting to an improper
value. But that too would be backward-incompatible.]
In Emacs 28.2, you get a similar wrong-type-argument error in
*Compile-Log*, but identifiying seq.elc, not cl-print.elc. And in Emacs
28.2 the *Help* buffer is shown normally (as in previous releases).
In Emacs 27 and prior there is no confusing display of buffer
*Compile-Log* with its error message that is only half-helpful.
