It doesn't happen for me.  The minibuffer frame has approx. two lines with this setup.

Hi Kim, that does sound quite right either - the minibuffer frame is
specified to have a height of 1, but you see 2 lines.  Or are you including
the WM title bar?

I've also replicated it with:

In GNU Emacs 22.0.50.1 (sparc-sun-solaris2.8, X toolkit)
 of 2006-06-19 on perth
X server distributor `Hummingbird Ltd.', version 11.0.100015
configured using `configure '--with-x-toolkit=lucid' 'CFLAGS=-g''

I've tried to attach a screen dump of what I see with the LUCID toolkit.  As
you can see, the tail of the "g" in "Auto-saving...done" cannot be seen (and
nor can the very bottom of the scrollbar).

Also notice that the minibuffer frame is slightly wider than the *scratch*
frame. There are extra pixels to the right of the fringe.

The display engine requires that window height is an whole multiple of
the default frame line height.  So if 1 line is not enough, the next
choice is 2 lines.

I don't know why Emacs selects one line in your case, and 2 lines in my
case.  It could be some property of the font -- I don't know.

Could be that the mode line font (or the minibuffer font after
font-lock) in one case is larger than one line of the default font,
and in one case isn't.

I don't think it can be the mode line font as the minibuffer frame does not
have one.  But I tried with different minibuffer fonts, and it looks as
though you both are on to something.  I've attached a screenshot with:

[1]  +  9267 Running	src/emacs -Q --font=5x8 --eval  ...
[2]  -  9272 Running	src/emacs -Q --font=6x13 --eval  ...
[3]     9275 Running	src/emacs -Q --font=9x15 --eval  ...
[4]     9282 Running	src/emacs -Q --font=10x20 --eval  ...

You can see that with the 10x20 font, the hanging parts of the letters are
displayed.  The other fonts are not displayed with sufficient space for the
letters.  I'm not sure it is quite correct even with the 10x20 font though -
there is (exactly) enough space for the letters but not enough for the
bottom of the scrollbar nor cursor box.

Note also that all fonts result in extra pixel space to the right of the
fringe.  Where does this come from???

I began to wonder if this is due to my X server, if that is the correct
terminology, which is Hummingbird's Exceed (I have the latest version).  I
use Exceed on my PC to provide the Solaris CDE environment on my PC.  Exceed
is using the Solaris' font server.  I am using a CVS Emacs built on Solaris.
I tried displaying the same Emacs on a GNU/Linux machine (some flavour of
RedHat) which is presumably running some Xfree86 server or something.  On
that display, I do not see a problem with either character space or fringe
space.  So presumably it is related to the information that Emacs is getting
from the Solaris font server via Exceed?  I do not know how to determine
where the problem lies: it may be that Emacs is not dealing with the
information properly.  I do not see any problems with any other applications
I use.

There is an additional problem that may help here.  If I start Emacs with:

src/emacs -Q --geometry=80x20 --font=9x15

Then under Exceed I get an Emacs frame containing a *scratch* buffer whose
window is 78x17 in size as reported by window-width and window-height.  On
the GNU/Linux box, the window is 80x19.

How can I help find what the problem is?

Simon.

It must be a dicision made during frame creation, i.e. before any text
is displayed in the minibuffer window (which is the only window in the
detached minibuffer frame.

So in my case, the frame is created with two lines, in Simon's case it
is created with one line.  Depending on the point of view, both
behaviours may be correct, but the question is what controls this.

RE: [simon.marshall@misys.com: Detached minibuffer cropped text]

[Marshall, Simon]

Here's yet another quirk that may help track down the problem.  From the
original bug report, if I do:

xrdb -load
^D
src/emacs -Q --font=9x15 --eval '(setq minibuffer-frame-alist (quote ((width
. 80) (height . 1))) initial-frame-alist (quote ((minibuffer))))'

Then the detached minibuffer has insufficient space for the trailing parts
of 9x15 characters such as "y".  Also, there are a few pixels to the right
of the right fringe.

If I put WM focus in the detached minibuffer and do:

M-x set-frame-font RET 9x15bold RET

Then Emacs resizes the minibuffer frame to have sufficient height for 9x15
characters and removes the extra pixels to the right of the right fringe.
The same thing happens if the default font is 9x15bold and then I change it
to 9x15.

This suggests to me that it is somehow a problem within Emacs - it does not
get it right on startup but it does get it right if the font is changed
while running.

How can I help you track the cause of this?  Simon.

Ok, everyone's had enough of a chance to respond! ;-)

Now I've got a gcc build, I tried to debug this myself, concentrating on the
frame height issue.  I started emacs with these breakpoints:

Breakpoint 5, Fx_create_frame (parms=5003429) at xfns.c:3161
Breakpoint 3, x_set_font (f=0x5bb200, arg=5495731, oldval=4687873) at
frame.c:3067

And then continued until the 3rd time we stop in Fx_create_frame(), when
we're creating the minibuffer frame:

if we exit x_new_font() and contiune in Fx_create_frame(), we get:

where:

i then let it continue to create the minibuffer frame.  the minibuffer frame
is the wrong size.  in *scratch*, if I eval (frame-parameters (car
(minibuffer-frame-list))) i get:

my session died and i had to start again.  i got to this point again, where
emacs is running and has created the *scratch* and minibuffer frames.

so i move the mouse to the minibuffer frame and do M-x set-frame-font RET
(with the intention of changing it to 9x15bold) and i hit here:

"*"
(gdb) 

when we search through the cached list, naturally we fail to find it.  so we
then end up calling XListFonts() because maxnames=-1 (and size=0) so we set
try_XLoadQueryFont=0, and since this time the pattern is "*" we get a huge
list of fonts back, including 9x15bold.

i'm not sure what to make of this.  the first time (when we're creating the
minibuffer frame), x_list_fonts() asks XLoadQueryFont() for "9x15bold" but
gets back "-Misc-Fixed-Bold-R-Normal--15-140-75-75-C-90-ISO8859-1".  the
second time (when calling set-frame-font), x_list_fonts() asks XListFonts()
for "*" and gets back a huge list including 9x15bold.

So is it the fault with XLoadQueryFont()?

Or should emacs use XListFonts() in either case?

And surely, if Emacs gets to understand that 9x15bold is equivalent to
-Misc-Fixed-Bold-R-Normal--15-140-75-75-C-90-ISO8859-1, shouldn't Emacs
always assume that?  (In other words, if Emacs fails to get the right font
when creating the minibuffer frame, should it not also fail when doing
set-frame-font?)
