Hi J.T.:
Any chance you can come up with a patch?
Thanks,
Bernard

I'm having a few problems with a new web interface deployment that I
haven't been able to debug. When the home page refreshes, or one of
the buttons at the top of the page are selected, the generated URL
opens an empty page.
For example, after a refresh I get:
http://ganglia.example.com/ganglia-2/?r=hourcs=ce=m=load_ones=by+namec=tab=mvn=hide-hf=false
I've found when I manually remove the hide-hf=false from the URL,
the page renders, but I have not yet been able to determine where this
is generated, or why the page doesn't render when it's present.
I've since tracked this down to:
if (isset($_GET[hide-hf]) filter_input(INPUT_GET, hide-hf,
FILTER_VALIDATE_BOOLEAN, array(flags = FILTER_NULL_ON_FAILURE))) {
$data-assign(hide_header, true);
}
in header.php and footer.php, and the fact that PHP on Centos 5.5 is
5.1.6, thus predates filter_input(). I commented these two lines out,
and now the web UI works as expected.
Since these are the only two places where filter_input() are used,
thus the only thing requiring PHP 5.2+, it may be worth using back-
wards compatible code to fetch the hide-hf param. The other params
are not validated, and I can't see what makes hide-hf more important.
