Automatic process: What's the problem?
Date: Mon, 9 Nov 92 19:05 MET
From: email@example.com (Tao JIANG)
I have defined an automatic process to copy the user files from one
Symbolics machine to another. I use this as an alternative to the
(defun backup-all-user-files ()
(cp:execute-command "copy file"
:output-destination (list #p"dom:>backup-log.text")))
But there is a problem: when the time is due, the machine says
"Automatic Backup Process wants to type out.
Select Automatic Backup Background Stream by typing Function-0-S."
And the process waits there without doing anything. When I type
Funtion-0-S, a window exposes and displays "Automatic Backup
Background Stream" at the bottom of the window (nothing else on the
window because I have redirected the output to a file). And the
process continues until it ends.
Does anyone know what the problem might be?
If I remember correctly, the command processor (or the command body or
something) outputs a newline at the end, which is causing the
background stream notification. Try binding various streams (in
particular *standard-output*, *error-output*, *query-io* and
*standard-input*) to 'si:null-stream around the call to
execute-command and see if that helps. I don't have my Lispm handy,
or I'd check this out.
