It works fine if called from a normal script.
Any ideas?
My hunch is that the END block is getting triggered before INIT
somehow, so the show_used symbol isn't getting bootstrapped - see if
this helps:

OK. I'm not that much of an expert, but I'll have a go: The relevant thing to look at is the include_cgi function of mod_include.c It works by triggering a GET subrequest for the relevant CGI include. (Have a look at ap_sub_req_lookup_uri() in http_request.c) So what we need to do is persuade Apache that this subrequest (which is still in the URI space of the local server) really wants to be subjected to the same rules (ie the proxy stuff) as a genuine request. Now, IIRC, there *is* a way to do this - for much the same reasons that per-directory configuration for mod_rewrite works. I'll have a dig about in the mod_proxy documentation and see how/if subrequests are made to behave like real requests. Ben
Apache question
I ummed and ahhed for a bit before posting this here, since it isn't about Perl or perlmongers. But I guess if we can talk about beer and ADSL, we can talk about apache. Can I make apache proxying and server-side includes play nicely together? I have a lightweight server serving static content and server-parsed files, and proxying dynamic content through to a mod_perl server. Unfortunately the server-parsed pages have '#exec cgi' directives in them, and the mod_perl server just isn't seeing those requests. Am I trying to do something impossible? When I enable ExecCGI on the lightweight server everything works fine -- but I don't want that server to be serving out cgi. And I'm sure my rewrite rules are OK because when I turn ExecCGI off again on the lightweight server and call the things that are 'exec cgi'ed directly, the mod_perl server sees and serves them up fine. The interesting parts of the relevant config files are: -- apache_plain.conf: # proxying to the mod_perl server ProxyRequests off ProxyPassReverse /cgi-bin/ http://localhost:82/cgi-bin/ RewriteEngine on # make sure that static and SSI content is served by plain server RewriteRule \.(gif|jpg|html|shtml|css|txt)$ - [L] RewriteRule ^/(.*\.)(cgi|pl)$ http://localhost:82/$1$2 [P] -- apache_perl_ukps.conf: PerlModule Apache::DBI PerlModule DBI SetHandler perl-script PerlHandler Apache::PerlRun Options +ExecCGI PerlSendHeader On -- I really, really don't want to be serving out the server-parsed files from the mod_perl server, since this is a very busy site and I'd have to set MaxClients so high that we'd be out of RAM in no time. (This was the rationale behind splitting out the dynamic content -- a high value for MaxClients on the lightweight server and a lower one on the bigger mod_perl process.) Can anyone help?

First suggestion is to update to 0.90_05 (available from www.class-dbi.com), which in the next day or two is going to become 0.90. It gives better error messages for some deep recursion cases that might help you track the problem better... If that doesn't help, then feel free to send me your code off-list (or to the CDBI mailing list), and I'll see if I can spot anything. Thanks, Tony

Well, if I have a parent object which has a collection of child objects of some class (or collections of objects of different classes), it seems like the parent should know what it has to do to add a child to (one of) its collection(s), as long as you give it the right data for the new child object. As it is, the parent can retrive objects it contains but can't add more, so the programmer has to know what class the child objects are in order to add more of them. > > I've overridden 'has_many' with a version that does what I want, but my > > question is, am I missing a trick?

I'll send it off-list unless anyone else is interested. While we're on the subject of Class::DBI, I'm getting deep recursion in Class::DBI::DESTROY. It's the call to $self->id at line 501 that seems to set it off, but if I take out my triggers it works. Probably something I'm doing wrong and I've got the perl debugger on the task, but if anyone has any suggestions about where to look I'd love to hear them. Thanks. michael

Very interesting approach...

Technically, if you were doing it this way, you should probably do:
my $survey = Survey->retrieve($survey_id);
my $qn = Survey::Question->create({ %question_data, survey => $survey });
as some databases might complain that you're violating the schema at the
initial create (as your foreign key is null until the next statement).
But I definitely like the first approach.

I don't think so. Would you mind submitting a patch?

st peter's ale
On another mailing list (I was thinking of you! honest! they meant nothing) where we were having the perpetual "What pub shallw e go to next" discussion I mentioned The Jerusalem Tavern and said that I liked St Peter's ale. I got this reply - Begin forwarded message - > That St. Peter's the branding exercise, right? Boy Jackson has the odd > tale to tell... Hmm. I read a depressing article in a weekend supplement a while back. St. Peters was created by the former head of Interbrand (they came up with the PriceWaterhouseCoopers - phew, that took some getting out - concept, among other pieces of genius...). This guy went on about how he'd always wanted to own a "brand", and stated that all it took was a couple of pubs, a brewery, and some nice bottles. There was a comment something like "What's in the bottle doesn't matter, just what it looks like", and some stuff about outsourcing most of the production to Scottish and Newcastle or similar. I quite like some of the beer, and I've never been to one of the pubs, but my attitude them has never quite been the same since I read the article... - End forwarded message - That makes me feel dirty - even though I love the ale. Anybody know anything else? Simon
