Re: Subversion and the Dynamic Website

If your ColdFusion developers are using Eclipse with the CFEclipse
plug-in, consider using the Subclipse plug-in for Eclipse to facilitate
Subversion interactions. This way, your developers don't have to go in
and out of th IDE to commit changes. It also allows your designers on
Mac's (if you have any) to work the same way.

To test your site on the development (aka QA) server and to deploy to
production, consider make your websites (including production) a
Subversion working copy. This allows for easy deployments and quick
rollbacks through the command line with this simple command, svn update
-r XXXXX (We XXXX is your revision number that your rolling out or back
to). All from Subversion with the command line client. No FTP, or
other protocol getting in the way or going through five windows and
forgetting a file. We've been doing this since Janaury with our
ColdFusion site. Rollouts are a breeze. Rollbacks are cinch. And we
know everything made it to the site as we intended.

A couple of things to do if you use the working copy approach to
deployments. First, checkout the site to your server with account that
does not have write privileges to the repository. As you should never
do development or changes on production and put them back. Second, make
sure you website cannot server up the .svn folder or anything in it.

Now, to the question about your CMS stuff. Create a second Subversion
repository (heck, create a new Subversion server, on the production
server). Access all the content via http from the Subversion repository
containing all the CMS files. Your developers can write code to get the
contents of the directory and map the link URL's straight to the
repository. To make this work, everyone and anyone must have read
access to the repository. To write, they will have to authenticate.
You can do this by setting up the CMS repository utilizing WebDAV and
auto versioning in Subversion. However, Windows Explorer does some
goofy things with WebDAV on Apache and authenticating with anonymous
access. Test it out. Have your users try it and see if it just bugs
them. If it does, find another way. It if doesn't, push forth. If you
control the upload of content through ColdFusion, your developers could
use the <cfexecute> command and commit the content to the repository.
