Splash screen and gnuserv

Splash screen and gnuserv

[Lennart Borgman]

I think there is a problem with the splash screen and gnuclient/server. 
I do not know if this problem exists with emacsclient/server, but it 
would be good if someone tested. Below is a description from a message 
in help-emacs-windows. I believe this is enough to describe the problem. 
I have tested this with

   In GNU Emacs 22.0.50.1 (i386-mingw-nt5.0.2195)

Here is a copy of the message:

Hi Denny,

Thanks for testing. I can reproduce the error here now. I will try to 
look into it.

It seems like this has something to do with the splash screen. If I turn 
off the splash screen the problem disappears.

To turn off it do

   M-x customize-option RET
   Customize variable: inhibit-splash-screen

and then set inhibit-splash-screen to "on" and save the value.

Does the problem disappear for you if you do this?

I can't reproduce this on GNU Emacs 22.0.50.14 (i686-pc-linux-gnu,
GTK+ Version 2.8.20).  I guess this is Windows-only.

Thanks. Does that mean that there is something in emacsserver that turns 
off the splash screen?

Was that what the problem was? It was not clear from the mail you
forwarded, but I thought the problem being reported was that
viper-mode came up in insert mode.

Nearly, but not quite. If the splash screen is active when gnuserv 
recieves the command to open a new file then something strange happens. 
The new file is shown, but the mode line shows the brackets (like 
[(Emacs-Lisp hs)] for recursive editing. There is a 'V' on the modeline 
so Viper should be in vi mode.

However when any key is typed it is inserted in the buffer instead of 
executed by viper. When the splash screen finishes the brackets 
disappears and now everything works as expected. A workaround for this 
problem is to turn off the splash screen.

So maybe this should be tested again with emacsserver? Sorry for not 
beeing clear enough before.

Have you tested it by starting Emacs, then after the splash screen comes 
up using gnuclient? Or are you only testing the case when gnuclient 
invokes Emacs because gnuserv was not running? The latter case will not 
be reproducable with emacsclient, since it does not start Emacs in that 
case. I wonder if the problem is only occuring when the gnuclient 
command comes during init BEFORE the splash screen is shown, which will 
be difficult to reproduce with emacsclient.

I started Emacs first (but using gnuclient for this too without any file parameter) and called gnuclient (again but now with a file parameter) when Emacs shows the splash screen.
