Package: emacs
Version: 24.5.1
* Brief summary
When I turn tool-bar-mode off and make a frame taller than the
height available on my screen the top of the buffer is hidden
until I re-size the window.
* Steps to reproduce
Here are the steps to reproduce the problem using the NS build of
emacs on OS X 10.10.4.
cat >> test-init.el <<EOF
(tool-bar-mode -1)
(setq default-frame-alist '((height . 100)))
EOF
open -a Emacs.app --args -Q -l ~/test-init.el
This opens a graphical emacs frame showing the *scratch* buffer.
Neither the cursor is visible, nor is the text normally shown in
the *scratch* buffer. Scrolling up will not make either of these
visible. C-x C-f <some file name> RET will display the contents of
that buffer with some or all of the lines at the start hidden.
The hidden sections of the buffer can be made visible by clicking
and dragging on any edge of the window and resizing it.
* Expected behaviour
When I set the frame size to be taller than the screen will allow, I
expect the frame to occupy as much vertical space as possible without
the top of the buffer being hidden. This is the behaviour seen when
tool-bar-mode is on.

This is probably beyond Emacs' control. I suppose that your window
manager normally tries to assure that the tool bar is visible. When
there's no tool bar it simply puts the frame somwhere if it's taller
than your screen.
What happpens when you also explicitly put the top left edge at some
visible position like with
(setq default-frame-alist '((top . 5) (left . 5) (height . 100)))

The below produces the same behaviour described previously.
cat >> test-init.el <<EOF (tool-bar-mode -1) (setq
default-frame-alist '((top .5) (left .5) (height . 100))) EOF open
-a Emacs.app --args -Q -l ~/test-init.el
In both the first example I gave, and this latest one the title bar and
all other edges of the frame are is visible on the screen. It does not
appear like my window manager has drawn a large window and put part of
it off the screen. The frame appears as if the top part of it was drawn
in the invisible area above the title bar.

Thanks for the clarification. I doubt it will help much but in such a
mangled frame please put the following snippet in *scratch* with point
after it, type C-x C-e, and post whatever it inserts here.
(progn
(insert (format "%s" (frame-geometry)))
(insert (format "%s" (frame-edges nil 'outer)))
(insert (format "%s" (frame-edges nil 'native)))
(insert (format "%s" (frame-edges nil 'inner))))
Also: Can you reproduce the problem with an already existing or another,
newly created one or is only the initial frame affected?

I was not able to find the functions frame-geometry and
frame-edges in emacs 24.5.1. M-x appropos found some functions
which appear similar however. Here is the results of evaluating
them in a mangled frame.

After resizing the window by dragging on its right border with my
mouse the frame became un-mangled. Here is the output for that
frame.

When I create new frames with command-n it is not affected. Only
the initial frame is affected under the conditions I described.
The result of running the above in a frame created with command-n
is:
(progn
(insert (format "%s" (current-frame-configuration))) (insert
(format "%s" (window-edges))) (insert (format "%s"
(window-pixel-edges))) (insert (format "%s"
(window-absolute-pixel-edges))) (insert (format "%s"
(window-inside-edges))) (insert (format "%s"
(window-inside-pixel-edges))) (insert (format "%s"
(window-inside-absolute-pixel-edges))))

I see. These are not very indicative though, they mostly tell what
Emacs thinks about itself.
The one thing that strikes me are the values for ‘window-pixel-edges’.
IIUC you get for a "mangled" frame (2 2 598 730) and for an "unmangled"
frame (2 2 598 702). Correct? If you put these frames side-by-side on
your screen, do they visibly have the same height and do they both have
no tool bar?
In any case 730 - 2 gives a presumed height of 728 pixels for the first
frame and 702 - 2 a height of 700 for the second frame. Would you say
that a mangled frame's window is missing 28 pixels at the top?
Anyway, could you try downloading one of the latest nightly builds from
here and try with them?
http://emacsformacosx.com/builds
Maybe the bug has been even fixed there.
Thanks, martin

Sorry for that. I shoudn't ask you to see things which are off-screen.

The latest nightly build [1] doesn't have the bug - I'll check
there first next time thanks!
