[Karrigell-main] Avoiding output buffering for pih-scripts

[Dr. B. Z. <be...@sc...>]

Hello to all,

I am using Karrigell with a pih-script and I am calling an external command.

As for example in apache with modpython the output from the os.system call
seems to be send unbuffered to the browser, so that one can see what 
happens.

In my Karrigell pih-script I tried different versions, but every time 
the output
from the external command is send buffered, so that one have to wait 
until the
external command is finished to see the result.

Is there a way to get the output from the external command send unbuffered
to the browser via Karrigell ?

Below is the code:
--- schnippp ---
<%
    print "<PRE>"
    print
    result = commands.getstatusoutput(command + ziel)
    print result[1]
    print
    if result[0] == 0:
        # TEST1
        #os.system(action + " " + option + " " + ziel)
        # TEST2
        #result = commands.getoutput(action + " " + option + " " + ziel)
        # TEST3
        result = os.popen(action + " " + option + " " + ziel, 'r', 0)

        for line in result:
            print line

    else:
        print "Check returns no result"

    print "</PRE>"

%>

Is there a simple solution, or is there perhaps a deeper modification in
Karrigell needed ?

If there are any hints, it would be great to get them.
I hope that somebody has got an Idea :-)
