This is possibly only a documentation issue.
Recipe: eval
(progn (push (lambda (&rest args) (message "window size changed"))
window-size-change-functions)
(message (make-string 3000 ?*)))
Expected result: a "window size changed" message.
Actual result: no such message.
The symptom is that the window size change function is not run after a
mini-window size change.
So far, I can produce this behavior only when the minibuffer or echo
area grows to several lines; when it shrinks afterwards, my window size
change function is called. I cannot reproduce the behavior with other
windows.
Is this a bug? The documentation says:
[...] to be called if the size of any window changes for any reason.
Please correct me if I'm wrong, but when the minibuffer/echo area gets
resized (and the windows on top of it, too), that counts as a change of
size, I would say.
If this is merely a documentation issue, the exception should be noted
in the manual.
Analysis:
First, some warnings:
- `window_resize_apply' and `Fwindow_resize_apply' (aka
`window-resize-apply') are two different functions
- `resize-mini-window' and `resize-mini-window-internal' are called
only when the mini-window is explicitly resized by a Lisp call of
`resize-mini-window'. Implicit resizes as a consequence of having
too much text in the echo area do not appear to call it.
The problem is that FRAME_WINDOW_SIZES_CHANGED (f) is not set to true
after a mini-window resize. Fwindow_resize_apply would set this flag,
but window_resize_apply does not.
If this behavior is deliberate, I believe it is inconsistent to set
FRAME_WINDOW_SIZES_CHANGED (f) in `resize-mini-window-internal'.
Suggested solution:
Trivial. Add FRAME_WINDOW_SIZES_CHANGED (f) = true to all callers of
window_resize_apply.
