Subject: bug#48408: BUGFIX: window-default-font-height: check for nil string
Date: Thu, 13 May 2021 21:15:19 -0400 [thread overview]
Message-ID: <20210514011519.vsy5jbhyxd4v6kpt@E15-2016.optimum.net> (raw)
In package windows.el, function `window-default-font-height' calls
function `face-font', which can return a nil value, but performs a
`string-equal' operation on the output without checking for that
possibiliy.
I came across this in an unusual case, of having an 'emacs -nw' server
an 'emacsclient -nw', and opening a GUI emacsclient to connect to it.
From that point forward until the fix, every *second* attempt to use the
minibuffer on the 'emacsclient -nw' would fail.
The fix I'm using is:
(if (and (display-multi-font-p (frame-parameter frame 'display))
(stringp default-font) ; <<<---!!!
(not (string-equal (frame-parameter frame 'font) default-font)))
But there could be other considerations to performing things in another way.
