[p4perl] sync problems

[Roger Day]

I've reset the client root and tried this command:

 my $val = $self->Run("Sync","-f", "$url");

where $url eq //depot/swig_tests/simple_build/product.xml#head

but nothing happens. I've upped the debug (using p4 -s P4DEBUG="server=1")
and all I get this:

Perforce server warning:
      2005/03/10 17:04:49 pid 2468 rday at mauberley 127.0.0.1 'user-client -o
mauberley'
Perforce server warning:
      2005/03/10 17:04:50 pid 2468 rday at mauberley 127.0.0.1 'user-client
-i'
Perforce server warning:
      2005/03/10 17:04:51 pid 2240 rday at mauberley 127.0.0.1 'user-client -o
mauberley'
Perforce server warning:
      2005/03/10 17:04:52 pid 1880 rday at mauberley 127.0.0.1 'user-client -o
mauberley'

which doesn't look meaningful to me. Are there any other tricks to try and
get the server to cough up more data? Why doesn't $! yield an error message
of some kind?

Roger.
