[Pbwebgui-development] Problems with Data::Config?

[Martin K. <maj...@gm...>]

Hi guys,

A few mothns ago I reported a bug about WebGUI not loading the WebGUI.conf
config ops correctly, or better said: not loading these things at all. At
first I thought it was a problem with a crappy compiled mod_perl provided with
RedHat 7.1.

To avoid this I installed Debian 3.0, and all was well. Until now... I just
had my second error on this configuration. My apache error log contains the
following, which is also shown in my browser window:

[Mon Sep 30 17:04:27 2002] [error] [Mon Sep 30 17:04:27 2002] null: Can't
connect(   HASH(0x8e638b8)), no database driver specified and DBI_DSN env var
not set at ../lib/WebGUI/Session.pm line 216

I backtracked this to see that the $session{settings}{dsn}/{dbuser}/{dbpass}
vars are  empty. I can only figure that the other configops in WebGUI.conf
(like logfile) are also not loaded. 

From my earlier experiences with this form of frustrating distress, I know
that Data::Config warned me about empty substitutions, From what I remember
they were in the read_source method. So I suspect Data::Config in combination
with my mod_perl for this. I've just put the use warnings; prama in
Data::Config to get a more extensive report of what's going on in there.

The problem is that the error appears to show up at random. At least, I
can't reproduce it. The two things I do know are:

    1) it only shows up after apache is running for some time
    2) when I run WG without mod_perl all works fine (but horribly slow,
ofcourse) 

Probably something goes wrong with mod_perls caching scheme or so.

I'm not exactly a mod_perl expert, but some of you undoubtly are. Do you
have any clue to what's causing this bug?

Martin
