[Xenomai-core] [patch] fix xeno-test for busybox

[-- Attachment #1.1: Type: text/plain, Size: 296 bytes --]

Hi,

I just tried to fire up xeno-test on a busybox system - without success.
Reason: missing getopts. But busybox initial test checks for something
else, namely getopt. The attached patch should fix this it, also taking
into account that getopts in a shell built-in, not an applet.

Another quirk: switchtest runs with hard-wired -T 120...

I agree that getopt is not used anywhere in xeno-test. Therefore we may skip 
the test.

But why do you want to eliminate the test whether getopts is really a built-in 
of the busybox? My intention was to simplify chasing the bug if someobody 
uses a busybox without a built-in getopts, e.g. Busybox option 
CONFIG_ASH_GETOPTS is not set.

I do not, please re-read the second part of my patch.

Dumb question about your patch...
Shouldn't you keep the -T option in the $pass variable, to pass 
it to latency?

        T) timeout=$OPTARG
            pass="$pass -T $timeout" ;;

The problem is that, if you don't put it in $pass, you must 
re-pass the latency option explicitly when logging, since it is 
no more in $pass, and is not in $loadpass. Otherwise,

script -c "`dirname $0`/xeno-test $loadpass $pass $*" $wfile

should become:

script -c "`dirname $0`/xeno-test $loadpass $pass -T $latency $*" 
$wfile


Therefore, I propose a slightly different patch. The -T option 
may be duplicated in $opts, but hopefully this is not a problem 
with the latency command?

A patch that avoid duplicating the -T option.
