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'.
|
|
|
|
[Update: 28-Mar-2003] I recently installed Redhat 7.2, as server, which
|
|
installed Apache 1.3.20 with mod_perl 1.24 and perl 5.6.0. I then ran the
|
|
CPAN shell (`perl -MCPAN -e shell') and after completing configuration, I
|
|
did 'install Bundle::CPAN', 'install Bundle::LWP' and 'install DBI' to
|
|
upgrade tose modules and their dependencies. These instructions work on OSX
|
|
as well, make sure you run the CPAN shell with sudo so you have sufficient
|
|
privs to install the files.
|
|
|
|
CGI::Request seems to have disappeared from CPAN, but you can get a copy
|
|
from <http://stein.cshl.org/WWW/software/CGI::modules/> and then install
|
|
with the standard `perl Makefile.PL; make; make test; make install'.
|
|
|
|
To install the SQL::Statement, Text::CSV_XS, and DBD::CSV modules, there is
|
|
a bundle available on CPAN, so you can use the CPAN shell and just enter
|
|
'install Bundle::DBD::CSV'.
|
|
|
|
At the end of this, the output for the test program above was the
|
|
following. (Note: you don't necessarily have to have the exact version
|
|
numbers for these modules, as far as I know, but something close would be
|
|
safest).
|
|
|
|
LWP::UserAgent, version: 2.003
|
|
SQL::Statement, version: 1.005
|
|
Text::CSV_XS, version: 0.23
|
|
DBD::CSV, version: 0.2002
|
|
DBI, version: 1.35
|
|
Time::HiRes, version: 1.43
|
|
CGI::Request, version: 2.75
|
|
URI, version: 1.23
|
|
MIME::Base64, version: 2.18
|
|
HTML::Parser, version: 3.27
|
|
HTML::Tagset, version: 3.03
|
|
Digest::MD5, version: 2.24
|
|
|
|
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
|
|
|
|
[Note - 28-Mar-2003: with Redhat 7.2, libgd.so.1.8.4 is preinstalled to
|
|
/usr/lib. The current GD.pm modules require libgd 2.0.5 or higher, but you
|
|
use 1.8.4 if you install GD.pm version 1.40, which is available at
|
|
<http://stein.cshl.org/WWW/software/GD/old/GD-1.40.tar.gz>. Just do 'perl
|
|
Makefile.PL; make; make install' as usual. I chose to build with JPEG
|
|
support, but without FreeType, XPM and GIF support. I had a test error when
|
|
running 'make test', but it works fine for my purposes. I then installed
|
|
'GD::Text' and 'GD::Graph' from the CPAN shell.]
|
|
|
|
5) To set this up with Apache, create a directory in the cgi-bin for the web
|
|
server called e.g. 'page-loader'.
|
|
|
|
5a) For Apache 1.x/mod_perl 1.x, place this in the Apache httpd.conf file,
|
|
and skip to step 5c.
|
|
|
|
--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<--------------------------------------------------------------------
|
|
|
|
[MacOSX note: The CGI folder lives in /Library/WebServer/CGI-Executables/
|
|
so the Alias line above should instead read:
|
|
|
|
Alias /page-loader/ /Library/WebServer/CGI-Executables/page-loader
|
|
|
|
Case is important (even though the file system is case-insensitive) and
|
|
if you type it incorrectly you will get "Forbidden" HTTP errors.
|
|
|
|
In addition, perl (and mod_perl) aren't enabled by default. You need to
|
|
uncomment two lines in httpd.conf:
|
|
LoadModule perl_module libexec/httpd/libperl.so
|
|
AddModule mod_perl.c
|
|
(basically just search for "perl" and uncomment the lines you find).]
|
|
|
|
5b) If you're using Apache 2.x and mod_perl 1.99/2.x (tested with Red Hat 9),
|
|
place this in your perl.conf or httpd.conf:
|
|
|
|
--8<--------------------------------------------------------------------
|
|
Alias /page-loader/ /var/www/cgi-bin/page-loader/
|
|
|
|
<Location /page-loader>
|
|
SetHandler perl-script
|
|
PerlResponseHandler ModPerl::RegistryPrefork
|
|
PerlOptions +ParseHeaders
|
|
Options +ExecCGI
|
|
</Location>
|
|
--8<--------------------------------------------------------------------
|
|
|
|
If your mod_perl version is less than 1.99_09, then copy RegistryPrefork.pm
|
|
to your vendor_perl ModPerl directory (for example, on Red Hat 9, this is
|
|
/usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi/ModPerl).
|
|
|
|
If you are using mod_perl 1.99_09 or above, grab RegistryPrefork.pm from
|
|
http://perl.apache.org/docs/2.0/user/porting/compat.html#C_Apache__Registry___C_Apache__PerlRun__and_Friends
|
|
and copy it to the vendor_perl directory as described above.
|
|
|
|
5c) When you're finished, restart Apache. 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'. [See 'urllist.txt' for further details on what needs to be
|
|
set there.]
|
|
|
|
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)
|
|
|
|
[MacOSX note: The web files live in /Library/WebServer/Documents, so you will
|
|
need to modify urllist.txt to have the appropriate FILEBASE and HTTPBASE.]
|
|
|
|
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) You will most likely need to remove all load event handlers from your
|
|
test documents (onload attribute on body and handlers added with
|
|
addEventListener).
|
|
|
|
10) Because the system uses (X)HTML base, and some XML constructs are not
|
|
subject to that (for example xml-stylesheet processing instructions),
|
|
you may need to provide the absolute path to external resources.
|
|
|
|
11) If your documents are tranformed on the client side with XSLT, you will
|
|
need to add this snippet of XSLT to your stylesheet (and possibly make
|
|
sure it does not conflict with your other rules):
|
|
--8<--------------------------------------------------------------------
|
|
<!-- Page Loader -->
|
|
<xsl:template match="html:script">
|
|
<xsl:copy>
|
|
<xsl:apply-templates/>
|
|
</xsl:copy>
|
|
<xsl:for-each select="@*">
|
|
<xsl:copy/>
|
|
</xsl:for-each>
|
|
</xsl:template>
|
|
--8<--------------------------------------------------------------------
|
|
And near the top of your output rules add:
|
|
<xsl:apply-templates select="html:script"/>
|
|
Finally make sure you define the XHTML namespace in the stylesheet
|
|
with "html" prefix.
|
|
|
|
12) I've probably left some stuff out. Bug jrgm@netscape.com for the missing stuff.
