#!/usr/bin/perl
# This file can find requirements of html and jhtml files (cgi, gif,
# java dependencies). It is a bit of a hack but it turns out to work
# well. We track only dependencies between Relative URLs, absolute
# URL's are assumed to be extenernal to the RPM system. We do not
# parse the HTML but look through the set of strings (text surrounded
# by quotes) for something which looks like a reference. This avoids
# writing a full HTML parsers and tends to work really well. In this
# manner we can track dependencies for: href, src, action and other
# HTML tags which have not been invented yet.
# The reference:
#
# href="http://www.perl.org/images/arrow.gif"
#
# does not create a dependency but the reference
#
# href="images/arrow.gif"
#
# will create a dependency.
# Additionally this program will find the requirements for sun jhtml
# (html with embedded java) since jhtml is deprecated so is this part
# of the code.
# These references create dependencies:
# <form action="signup.jhtml" method="POST">
#
# <img src="images/spacer.gif" width=1>
#
# <A HREF="signup.jhtml">
#
# adWidget.writeAd(out, "login.html", "expired");
#
# response.sendRedirect("http://"+request.getServerName()+"/mailcom/login.jhtml");
# Notice how we look for strings WITH the proper ending. This is
# because the java sometimes has really strange double quoting
# conventions. Look at how splitting out the strings in this
# fragment would get you the wrong text.
# <img src="`c.getImage("bhunterlogo.gif")`" width=217 >
# Ignore non relative references since these dependencies can not be
# met. (ie, no package you install will ever provide
# 'http://www.yahoo.com').
# I use basename since I have seen too many http references which
# begin with '../' and I can not figure out where the document root
# is for the webserver this would just kill the dependnecy tracking
# mechanism.
