Re: [webmin-devel] adding a "please wait" popup while executing time consuming commands

[marty l. <mal...@gm...>]

I still can't get the behavior I want where I print some text as soon as
possible and then wait.

Here's the relevant parg of a  test .cgi:

$start=qx(date);

ui_print_unbuffered_header('Changing communication mode');
$|=1;
print "started at $start\n<BR>";

my $type_ethernet=$in{'type_ethernet'};

my $type_wifi=$in{'type_wifi'};

set_wifi($type_wifi);
set_ethernet($type_ethernet);

$end=qx(date);

 print "ends at $end\n<BR>";

#print '<meta http-equiv="refresh" content="0;URL=index.cgi">';
footer();

The behavior of the "meta refresh" is what I want (at the end of the
script, go to another page)

But everything seems to print at once:  (with and without the $|=1 trick)

Changing communication mode
started at Wed Jun 4 03:36:49 UTC 2014
ssh stop/waiting ssh start/running, process 20496 ends at Wed Jun 4
03:36:56 UTC 2014

(there should be about a 7 second visual delay between the started and
ends, the data is transmitted instantenously).

I want the data to be transmitted when I write it.

 I've done lots of playing with this simple example wihtout different
results (seems the output is being buffered).

I have webmin being redirected through the SSL of nginx (though I can't
imagine that would be a problem)
