Unfortunately this a known problem. It is basically the unix terminal group mechanism which is getting our way here. The problem could be avoid if you could do 'xemacs -unmapped </dev/null &' or XEmacs could itself detach from its terminal. However this cannot currently be as XEmacs needs stdin to be a tty. This could be solved by -batch like mode (which has a stream device[1] and thus does not need a tty) that does not exit when some flag is set. Gnuserv-start could then set this flag. Alternatively 'gnuclient' could be me made to proxy the stuff to its own pseudo terminal like 'script' does. This would also make the signal forwarding a lot cleaner. Nobody has done the coding yet however. Jan Footnotes: [1] Unix XEmacs has 3! device types: X, tty, stream.

[crash] image display problem on 24bpp 25 years, 5 months

Kazuo Oishi

XEmacs inline image display cause crash on 24bpp X. 1. $ xemacs -vanilla 2. C-x C-f imagefile After broken (monochrome, vertical lined) image or nothing is displayed, XEmacs crashes. PNG, JPEG, TIFF, GIF formated image has this problem, and XPM does't. This is 100% reproductive in my one environment, but not occur in other environment. I heard some X server (for example, XFree86 SVGA I am using in the environment) handle 24bpp images without padding to 32bit and this cause image display problem in some software which handle image directly. I think XEmacs is one of them. uname -a: Linux agenv4 2.0.36 #1 Thu Nov 19 12:33:18 JST 1998 i586 unknown ./configure '--compiler=egcc' '--with-mule' '--with-xim=no' XEmacs 21.0-b61 "Poitou61" configured for `i586-pc-linux'.

It looks like it might be a logic error in configure because -ldl is being detected and added to the link command, but ld_dynamic_link_flags isn't getting set correctly. It appears to work when I explicitly add --with-shlib.

Because when Kai is finished we have at least 2 different methods for remote editing. /user＠host:path is currently taken by EFS/ange-ftp but I think it should be generalised to just mean "remote filename"/"special file name" and have Emacs figure out the best way of accessing based on user and site configuration. I think the above is a convenient syntax for those occasions you DO want to specify a specific method. Jan
