#130 Galaxia : graph doesn't show up in tiki-g-admin_graph.php

[Peter Niederlag]

the graph doen't show up in tiki-g-admin_graph.php
cause to wrong build path.
CONSTANTS 'GALAXIA_PROCESSES' has been used to
construct the img path which points to an absolute file
path. I change that to 'lib/Galaxia/processes' and it
works again.

patch attached.

HtH,

Hi, I don't use Galaxia, could you mention the versions
affected by this bug?
Thanks for sending this patch anyway, hopefully someone else
can review it.

It's the latest version from HEAD(CVS):
$Header: /cvsroot/tikiwiki/tiki/tiki-g-admin_graph.php,v 1.3
2004/02/14 23:48:29 halon Exp $

after some further investigation & using of tikiwiki/Galaxia
it seems like the problem should probably be adressed in a
better way by manually defining the GALAXIA_LIBRARY Constant
cause then it wouldn't contain the whole absolute path as
returned by 'dirname(__FILE__)';

config.php:
...
// Directory containing the Galaxia library, e.g. lib/Galaxia
if (!defined('GALAXIA_LIBRARY')) {
define('GALAXIA_LIBRARY', dirname(__FILE__));
}
....
define('GALAXIA_PROCESSES', GALAXIA_LIBRARY . '/processes');

The constant GALAXIA_PROCESSES should be set in
/lib/Galaxia/config.php, together with all the other Galaxia
constants. This makes sure the library remains free of
hardcoded paths.
That's also the place where you should define the path to
the Graphviz dot program. There's only one pitfall for the
Windows guys out there: make sure there are NO spaces your
paths. Graphviz doesn't like'em. That's no spaces for the
path to the Graphviz programs and no spaces in the tiki
installation dir... Unless your looking for trouble ;-)

hmm, i probable wasn't clear on that last one... sorry for
that. The only reasen why the graph isn't going to get
generated is when there are spaces in some path on a windows
system. I already comitted something like you patch some
time ago, but it got reverted, for good reason. This should
probably be mensioned in the docs somewhere...

time is always against us...

Halon, the problem is not spaces in the path, the problem is
that GALAXIA_PROCESSES refers to a server-absolute path, for
example, on my Linux box this path is
'/home/httpd/my_website_dir/html/lib/Galaxia/processes'.

This absolute server address is useless to a user's web
browser, it needs it specified relative to the webserver,
like '/lib/Galaxia/processes'.

Perhaps a new constant is needed, for web-relative paths.
In the absence of that, a hard coded path will have to do.

Why is this still broken in the 1.9 distro?
