Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

10.7 (Lion)

10.8 (Mountain Lion)

10.9 (Mavericks)

Build platform: Ubuntu 16.04LTS.

First things first:

Install baseline dependencies first

sudo apt-get -y install autoconf automake build-essential libass-dev libtool pkg-config texinfo zlib1g-dev libva-dev cmake mercurial libdrm-dev libvorbis-dev libogg-dev git libx11-dev libperl-dev libpciaccess-dev libpciaccess0 xorg-dev intel-gpu-tools

How to generate and apply patches with git?

It sometimes happen you need change code on a machine from which you cannot push to the repo. You’re ready to copy/paste what diff outputs to your local working copy.

You think there must be a better way to proceed and you’re right. It’s a simple 2 steps process:

1. Generate the patch:

git diff &gt; some-changes.patch

	mkfs.vfat -n BOOT /dev/sda1
	mkfs.btrfs -L root /dev/sda2

	mount -t btrfs /dev/sda2 /mnt/
	btrfs subvolume create /mnt/nixos
	umount /mnt/
	mount -t btrfs -o subvol=nixos /dev/sda2 /mnt/
	btrfs subvolume create /mnt/var
	btrfs subvolume create /mnt/home
	btrfs subvolume create /mnt/tmp

	# Lets say we want to add a library and an executable, both with the same name.
	# In this example, it is resman

	add_library(resman ${src_cpps} ${src_hpps} )
	target_link_libraries(resman ${Boost_LIBRARIES} ${LIBYAML} ${LIBFMT})
	#
	# Add resman executable
	#
	# We call the executable resman-bin
	add_executable(resman-bin main.cpp )
