bug#1802: 23.0.60; (with-ns) completion of font names does not work

[B. Smith-Mannschott]

Observed Behavior
=================

1. M-x set-frame-font

    Prompts for a font name, but offers no completions.
    (Is the user meant to guess?)

2. M-x set-face-font

    Prompts for a font name, but offers only the following three values
    as possible completions:

       -*-*-*-*-*-*-*-*-*-*-*-*-fontset-default
       -apple-Monaco-medium-normal-normal-Regular-*-*-*-*-*-*-fontset- 
startup
       -ns-*-*-*-*-*-10-*-*-*-*-*-fontset-standard

Expected Behavior
=================

I would expect a complete list of the fonts current installed on the
system to be offered for completion.  This is the behavior on Windows
and Linux as well as (Carbon)Emacs 22.

Note
====

It's not that font selection is completely broken. e.g. Choosing a
font from the font panel presented after selecting "Options >> Set
Defalt Font..." does work after a fashion: it sets the default font
for all windows of the currently focused frame. (Not, however, those
of other frames.)

Also, the following elisp code, will work:

   (set-face-attribute 'default nil
                       :background "#ffffff"
                       :foundry "apple"
                       :family "consolas"
                       :foreground "#000000"
                       :height 120
                       :slant 'normal
                       :weight 'normal
                       :width 'semi-condensed))

bug#1802: 23.0.60; (with-ns) completion of font names does not work

[Adrian Robert]

I get the message 'Invalid font name: "*"' in the minibuffer when I  
try this.  Some investigation seems to show this is generated in  
font.c before any NS-specific code is called.  Can you try this in an  
X build of the same source and report whether it occurs there too?

Indeed

(x-list-fonts "*")

as called by set-frame-font throws an error for me ("Invalid font name
*") in the current trunk on GNU/Linux.

`cvs up -D2009-01-18 font.c' and this goes away, so perhaps it is the
2009-01-19 change to font_spec_from_name?

(I don't think this is related to the original report.)

Should be fixed now.
