Rough notes on setting up this test app. jrgm@netscape.com 2001/08/05
1) this is intended to be run as a mod_perl application under an Apache web
server. [It is possible to run it as a cgi-bin, but then you will be paying
the cost of forking perl and re-compiling all the required modules on each
page load].
2) it should be possible to run this under Apache on win32, but I expect that
there are *nix-oriented assumptions that have crept in. You would also need
a replacement for Time::HiRes, probably by using Win32::API to directly
call into the system to Windows 'GetLocalTime()'.
3) You need to have a few "non-standard" Perl Modules installed. This script
will tell you which ones are not installed (let me know if I have left some
out of this test).
--8<--------------------------------------------------------------------
#!/usr/bin/perl
my @modules = qw{
LWP::UserAgent SQL::Statement Text::CSV_XS DBD::CSV
DBI Time::HiRes CGI::Request URI
MIME::Base64 HTML::Parser HTML::Tagset Digest::MD5
};
for (@modules) {
printf "%20s", $_;
eval "use $_;";
if ($@) {
print ", I don't have that.\n";
} else {
print ", version: ", eval "\$" . "$_" . "::VERSION", "\n";
}
}
--8<--------------------------------------------------------------------
For modules that are missing, you can find them at http://www.cpan.org/.
Download the .tar.gz files you need, and then (for the most part) just
do 'perl Makefile.PL; make; make test; make install'.
4) There is code to draw a sorted graph of the final results, but I have
disabled the place in 'report.pl' where its use would be triggered (look
for the comment). This is so that you can run this without having gone
through the additional setup of the 'gd' library, and the modules GD and
GD::Graph. If you have those in place, you can turn this on by just
reenabling the print statement in report.pl
5) To set this up with Apache, create a directory in the cgi-bin for the web
server called e.g. 'page-loader' and then place this in the Apache
httpd.conf file to enable this for mod_perl (and then restart Apache).
--8<--------------------------------------------------------------------
Alias /page-loader/ /var/www/cgi-bin/page-loader/
<Location /page-loader>
SetHandler perl-script
PerlHandler Apache::Registry
PerlSendHeader On
Options +ExecCGI
</Location>
--8<--------------------------------------------------------------------
So, now you can run this as 'http://yourserver.domain.com/page-loader/loader.pl'
6) You need to create a subdirectory call 'db' under the 'page-loader'
directory. This subdirectory 'db' must be writeable by UID that Apache
executes as (e.g., 'nobody' or 'apache'). [You may want to figure out some
other way to do this if this web server is not behind a firewall].
7) You need to assemble a set of content pages, with all images, included JS and
CSS pulled to the same directory. These pages can live anywhere on the same
HTTP server that is running this app. The app assumes that each page is in
its own sub-directory, with included content below that directory. You can
set the location and the list of pages in the file 'urllist.txt'. There are
various tools that will pull in complete copies of web pages (e.g. 'wget' or
something handrolled from LWP::UserAgent). You should edit the pages to remove
any redirects, popup windows, and possibly any platform specific JS rules
(e.g., Mac specific CSS included with 'document.write("LINK...'). You should
also check that for missing content, or URLs that did not get changed to point
to the local content. [One way to check for this is tweak this simple proxy server
to check your links: http://www.stonehenge.com/merlyn/WebTechniques/col34.listing.txt)
8) The "hook" into the content is a single line in each top-level document like this:
<!-- MOZ_INSERT_CONTENT_HOOK -->
which should be placed immediately after the opening <HEAD> element. The script uses
this as the way to substitute a BASE HREF and some JS into the page which will control
the exectution of the test.
9) I've probably left some stuff out. Bug jrgm@netscape.com for the missing stuff.
