Git Guide

From Buici

These are my notes on what I've discovered about using git. Jeff Garzik has a [[1][guide]], too.

Contents 1 Getting Started 2 Creating a Working Directory 3 Branching with Tags 4 Update Cache for All Changed Files 5 List New, Uncommitted & Uncached Files

Getting Started

I maintain on repository that is an unmolested clone of the upstream source.

git clone rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git linux-2.6

This creates a directory, linux-2.6/.git with the mirror of the repository. If your version of git is new enough, it will fetch tags as well as the object database.

Creating a Working Directory

Find a comfortable workplace with enough disk space to checkout and build the kernel. Clone the local repository.

git clone /repository/linux-2.6 work

Branching with Tags

If you want to develop patches against an earlier point in the development tree, create a branch at that tag.

cd work
git checkout -b my_branch v2.6.11

Update Cache for All Changed Files

This may be made easier at some time in the future.

cd work
git-update-cache `git-diff-files | cut -f2` 

List New, Uncommitted & Uncached Files

This one doesn't appear to have an analog in git. Cogito has a command that will show the unmanaged files.
