A question about revision control.

[antjoh]

I consider myself to be a beginner when it comes to revision control so bare with me if these questions and thoughts sounds silly.

What I am trying to figure out is how to handle patching in a project using subversion. Let me explain it like this:

Say that I have a project in trunk that looks like this:

MyProjektDir
    |
    |
    ---- DirOne
    |        |
    |        |
    |        ---- FileOne.php
    |        |
    |        ---- FileTwo.php
    |
    ---- DirTwo
    |        |
    |        |
    |        ---- FileThree.php
    |
    ---- FileFour.txt
    |
    |
    ---- FileFive.php

I have made a tag on the whole project and called it "Release 1.0".
Now I realize that I need to make an adjustment to FileTwo.php and FileFive.php to fix a bug.

Now, in order to not have to extract the whole project to fix the installation, I would like to only check out the two files that I have made changes to. Basically I want to create a "patch" containing FileTwo.php and FileFive.php.

Then eventually, when further changes have been made to the project I will tag the whole thing and call it "Release 2", where the "patch files" of course will be included.

So, I guess my question is: How do you handle these situations? Is it possible to tag only a part of a project and call it eg "patch 1" so that I can easily find the two files that I need?

It is my understanding that this is not possible to do in subversion, so how should I handle this?

I have read that in subversion "every revision is a tag" which leads me to believe that I must always tag the whole project. Are there other revision control software available that handle these types of situations better, or am I just simply handling this the wrong way?

Any advice is much appreciated!

Read the release branches section in:

Yes, you need to tag the whole project but you should be able figure out the difference between say 1.0.1 and 1.0.0 by issuing an svn command and just copy over those files for your patch.
