As you may well know, I run cvsup.nz.freebsd.org. On that server, but for my own use, I use cvsweb. This port allows you to browse a CVS repository via the web. When I first encountered this tool, I thought it was great. But recent advances have improved it. There is now a .conf file into which you can customize various options. Not to mention that the output and user interface are improved. Personally, I like the coloured diff output.

cvsweb is of no use to you unless you have the following on your box:

a web server (presumably Apache)
a cvs repository

By the way, cvsweb will also run on NT according to what I've read.

Other reading

I suggest you have a read of these resources before you continue. And if you have problems, go there first.

/usr/local/share/doc/cvsweb/ has the documentation for cvsweb
http://www.cyclic.com/ is the home page for cvs. But I notice they have recently rebranded to site to be http://www.cvshome.org/ which looks very nice.

Installing

This should be familiar to you now. Since I have the entire ports tree installed, all I needed to do was:

/usr/ports/devel/cvsweb
make
make install

*** BUT: before you do the install, read about the Makefile variables which allow you to customize the install. ***

There are a few things you must be careful with. My configuration was not the default. Therefore, I had to move some things around. The next few sections deal with how I did those moves.

After I wrote this article, Akinori -Aki- MUSHA provided some feedback which included details on the Makefile variables.

cgi-bin location

My cgi-bin directory, and indeed my Apache location, is not standard. The port install had put cvsweb.cgi here:

/usr/local/share/apache/cgi-bin/cvsweb.cgi

So I moved it to my actual cgi-bin directory:

/nzmirror/www-nz.freebsd.org/cgi-bin/

But there is a better way. See Makefile variables.

The configuration file

cvsweb uses the cvsweb.conf configuration file. You are supplied with an example file. By default, this is installed to /usr/local/etc/. And it is up to you to take a copy of this sample file:

cp /usr/local/etc/cvsweb.conf.sample /usr/local/etc/cvsweb.conf

In the configuration file, you'll find a section which refers to the CVSROOT repositories which cvsweb can expect to find on your box. By default, it assumes you have a local cvs repository as well as the FreeBSD repository. That is not the case on my box. I have only the FreeBSD repository. So I had to remove the references to the local repository. Here's what comes with the sample configuration (this may be OK for you, maybe not).

To make it clear, the parts I changed are in bold.

# 'symbolic_name' 'path_to_the_actual_repository'
%CVSROOT = (
            'local'     => '/home/cvs',
            'freebsd'   => '/home/ncvs',
           );

%CVSROOTdescr = (
                 'local'     => 'My CVS Repository',
                 'freebsd'   => 'FreeBSD',
                );

# This tree is enabled by default when
# you enter the page
$cvstreedefault = 'local';

Then I modified this file like this. You'll see I removed references to local and changed the default to FreeBSD.

# 'symbolic_name' 'path_to_the_actual_repository'
%CVSROOT = (
            'freebsd'   => '/nzmirror/ncvs',
           );

%CVSROOTdescr = (
                 'freebsd'   => 'FreeBSD',
                );

# This tree is enabled by default when
# you enter the page
$cvstreedefault = 'freebsd';

Icons and bitmaps

cvsweb uses a number of icons and bitmaps. By default, these were installed to /usr/local/share/apache/icons/cvsweb/. I moved these to where my installation of Apache could find them:

cp -R /usr/local/share/apache/icons/ /nzmirror/www-nz.freebsd.org/icons/

But there is a better way. See Makefile variables.

Makefile variables

The makefile for cvsweb contains two variables which specify the location of the cgi-bin directory and the icons. You can specify the values for these variables and the install will use those locations.

For instance, if your cgi-bin is at /usr/local/www/cgi-bin and your icons directory is at /usr/local/www/data/icons, then you can do like this:

cd /usr/ports/devel/cvsweb
make CGIDIR=www/cgi-bin ICONSDIR=www/data/icons build install

This assumes that PREFIX is /usr/local (as is the case with the default ports tree; you'll know if you've changed it).

Seeing the output

You should now be able to use cvsweb by browsing to http://localhost/cgi-bin/cvsweb.cgi.

Problems I encountered

Along the way, I encountered this error:

Error: $CVSROOT not found!

The server on which the CVS tree lives is probably down
Please try again in a few minutes.

This means cvsweb cannot find your cvs repository. Or, your configuration file specifies a cvs repository which does not exist on your box. That's why I removed 'local' from the configuration file. Check your settings against mine and try again.
