Apache::Gallery
Hi, Apache::Gallery is a picture gallery implemented as a mod_perl handler, using libgd2 for on-the-fly image resizing (resized pictures are cached) and CGI::FastTemplate for easy customization. Demo can be seen at http://pictures.legart.dk/ordb/ and source can be downloaded from http://legart.dk/code/Apache-Gallery-0.1.1.tar.gz It is still at a very early stage, but i have alot of ideas for improvements... Would it be ok to upload this to CPAN in the Apache namespace? Thanks, Michael

Re: Using DOM to build your output documents
On Thursday 04 October 2001 01:43, Jeffrey W. Baker wrote:
I believe that the canonical way to output a document using any web
scripting language (Perl CGI, mod_perl, PHP, ASP, etc.) is to simply print
out your markup, like this fictional example:
while (my $row = $sth-fetchrow_arrayred()) {
print trtd$row-[0]/tdtd$row-[1]/td/tr\n;
}
Yes, and I agree with you that this approach has severe drawbacks. Years of
practice have made it usable through templating systems and various tricks
that people discover as they learn. The linearity is one of the main problems
as if the beginning of your output is dependent on something farther down you
often have to resort to complex lookaheads. There are also problems with
coupling, in that code meant to process one data structure into a string will
often be able to process only that data structure. It's hard to make this
approach generic, or even to abstract large parts of it. And recursing into
arbitrarily deeply nested structures is up to you, whereas using the DOM with
XPath (or iterators), or XSLT takes care of that for you.
Another major advantage is pipeline processing. You can have several
processors in a row, all of them specialised and dealing with the same kind
of data structure (a DOM). This is similar to using filters, but filters are
painful and require reparsing at every stage. I find it much easier to use a
pipeline model, especially when I want to add a new feature as that new
feature will live on its own, separate from the rest of the code.
I'd love to hear any other experiences with using the DOM to build output
from scratch. I'd also like to hear people's opinions on XML::DOM (I
think it stinks and I've replaced it with a C DOM implementation).
I gave up on XML::DOM the day I tried to patch it to make it DOM 2 compliant
(or even only to add namespace support). I tend to use SAX whenever I don't
need lookahead, and XML::LibXML for everything DOM related. It isn't 100%
complete but it's close, and will soon be. Watch perl-xml for an annoucement
of PerlDOM, as it seems likely to happen soon.
In all of my recent websites I've used combinations of DOM and SAX
processing, always with a pipeline approach. Most of the time this happens in
AxKit but there are exceptions where I decided to hand build a few things. I
also tend to make a growing use of XSP as it allows you to express the output
XML DOM you want from your code in quite a direct manner. As all
templating-like approaches you've got to be discplined for it to be readable,
but that's easy enough. And more importantly, writing taglibs (in order to
avoid embedded code) is rather trivial if you know SAX (and SAX is far from
being hard to learn).

[patch] overriding per directory PerlSetEnv
Hi,
I rescently started to use mod_perl. It works fine, but a
strange behavior have found. I have written a patch that collect
the behavior. Please comment this.
I think that per directory PerlSetEnv variable should be
overridden by the value that in the most specific(longest)
Directory section.
http://localhost/cgi-bin/subdir/printenv with following config
will generate VAR=/usr/local/apache/cgi-bin/subdir, but
generated result is VAR=/usr/local/apache/cgi-bin.
Directory /usr/local/apache/cgi-bin
PerlSetEnv VAR /usr/local/apache/cgi-bin
/Directory
Directory /usr/local/apache/cgi-bin/subdir
PerlSetEnv VAR /usr/local/apache/cgi-bin/subdir
/Directory
Following patch corrects this behavior by modify overriding
logic. It seems work well.

Re: [patch] overriding per directory PerlSetEnv
i don't think it is supposed to work this way according to the apache documentation. if you want the most specific (longest) one to take precedence, put it before the shorter one in the config file. the relevant documenation is here: http://httpd.apache.org/docs/sections.html YAMAMOTO Kengo wrote: I think that per directory PerlSetEnv variable should be overridden by the value that in the most specific(longest) Directory section. http://localhost/cgi-bin/subdir/printenv with following config will generate VAR=/usr/local/apache/cgi-bin/subdir, but generated result is VAR=/usr/local/apache/cgi-bin.

RE: shared libraries
It sounds like you either haven't obtained the B:: module, or there was a compilation problem. You can try to get your current server up and running by commenting out the PerlModule B:: ... references, then try starting it up. Check on the Perl and Apache web sites (www.perl.org, www.apache.org) for information about properly incorporating/using modules with Apache and mod_perl. The perl site has PerlModules available for download if you need the code.
