The source code of collectd is organized in a Git repository.
The official repository is available from:
To clone the repository use:
$ git clone git://git.verplant.org/collectd.org
If you're more comfortable using Github you can use the mirror available there. Its web address is:

How to check out a specific branch
“… the changes are in the ‘foobar’ branch.”
Usually this happens when a patch is not yet ready to be applied to the master branch (see below) and needs some review. For example, the main developers did some changes and ask you to verify that they didn't accidentally break anything.
To check out this ‘foobar’ branch, you have to clone the repository first, using the git clone command (see above). After that is done, “cd” into the newly created
collectd/ directory. There you have to create a local copy of the branch, using:
git branch --track foobar remotes/origin/foobar
Then you have to check out that branch:
git checkout foobar

We maintain three branches: One development branch (named “master”) and two bugfix branches. The first bugfix branch corresponds to the latest release, the second bugfix branch corresponds to the second latest release. Those are the versions we provide bugfixes for. At the time of this writing (August 2010), those versions were “collectd-4.10” and “collectd-4.9”.

Bugfixes are applied to the earliest branch possible. If a bug existed for a while, this is probably the “bugfix1” branch. If the bug was introduced in the latest release (i. e. “collectd-4.9” currently), then the fix is applied to “bugfix0”. If the commit fixes a bug that has not yet been released or adds a new feature, it is committed to the “master” branch. From time to time, the “bugfix1” branch is merged into the “bugfix0” and the “bugfix0” branch is merged into “master”, so that bugfixes are included in all appropriate branches.
With the release of version 4.9 the “collectd-4.8” branch became the new “bugfix1” branch and the “collectd-4.7” branch is now obsolete. Release 4.7.5 was created so that the “collectd-4.7” version does not fall into oblivion with unreleased bugfixes still in the appropriate branch.
There are a couple of templates that make it easy to point to stuff in the repository.
