Subject: kill-buffer calls frame's buffer-predicate for all buffers even if the killed buffer was not shown in any window.
Date: Sun, 15 Jan 2017 22:32:10 +0300	[thread overview]
Message-ID: <CAFkz2yqH6ruYjisdpOv8+Ao=0CMBxv0qPC1DQ+4vRJfoY5Oa3w@mail.gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 373 bytes --]

For example:

emacs -Q

M-: (set-frame-parameter nil 'buffer-predicate #'(lambda (b) (message
"f-b-p: %s" b))) RET
M-: (with-temp-buffer nil) RET
C-x b *Messages* RET

See that all buffers listed except of the *temp*(no window buffers were
changed). Why?
This is inefficient, especially for the with-temp-buffer which is used very
frequently in emacs and in side packages.
