Great : I haven't heard before of someone using JASmine on Freebsd, so
this is great new we may succeed to validate this ;-)

Hmmmm, the real backend doesn't seem to run correctly... First, which
release of JASmine are you using ?
Ok, let's look at those logs... :
> jasmine[22935]: Arguments:

> job-uuid=urn:uuid:4d1151ec-51d2-330b-5d47-0a0d40475d38
These arguments are : $job_id, $user, $title, $copies, $options, $file. We
can notice that $file is not provided, but we'll see later that this is
expected...

Yes...

"Is" ? Is what ;-) ? I think we found the problem...

Nothing here ? Well, the problem really is identified ;-) !

The backend does not receive the file to print, as "expected".

...And seems to be angry.
Ok, here is the code, in JASmine-Backend, that produces the bug :
---------------------------------------------------------------
# If we were called with 5 arguments, read from STDIN to a tempfile:
if (@ARGV == 5){
# TODO : This is not portable, use File::Temp instead !
my $tmpcmd = "/bin/mktemp </dev/null ".$ENV{"TMPDIR"}."/print.XXXXXX";
$tmpfile = qx{$tmpcmd};
chomp $tmpfile;
# TODO : This is not portable too !
qx{cat > $tmpfile};
# ...And set $tmpfile to be the document to print
$doc = $tmpfile;
log_debug (" Called with 5 args, \$doc is read from STDIN and the
tempfile is $doc");
}
---------------------------------------------------------------
And, as written, it's not portable code : It was going to annoy us sooner
or later. Ok, so now, I really gonna fix this code, and maybe JASmine
will run on *bsd ;-) !
I will provide a fix for this issue in the next days. Then, when it works,
it will be included in release 0.0.4, and I will check all the code for
other portability issues (Well, those I can find on my own).
One thing to end this mail : The JASmine project is very slow, and you may
have expected more releases, I'm aware of that. Let's say that between
work and family, time is sometimes hard to find... So, all code
contributions are welcome ;-)
