Notes made while installing Git 1.5.2.4 on Mac OS X Leopard.

Installation

# build expat dependency
curl -O http://surfnet.dl.sourceforge.net/sourceforge/expat/expat-2.0.1.tar.gz
tar xzvf expat-2.0.1.tar.gz
cd expat-2.0.1
./configure
make
make check
sudo make install
cd ..

# build GPG for signature verification
curl -O ftp://ftp.gnupg.org/gcrypt/gnupg/gnupg-1.4.7.tar.bz2
openssl sha1 gnupg-1.4.7.tar.bz2
tar xjvf gnupg-1.4.7.tar.bz2
cd gnupg-1.4.7
./configure
make
make check
sudo make install
cd ..

# copy GPG files from Tiger install
mkdir -m 700 ~/.gnupg
 cp ${PATH_TO_TIGER_HOME_FOLDER}/.gnupg/*gpg* ~/.gnupg/

# git
curl -O http://kernel.org/pub/software/scm/git/git-1.5.2.4.tar.bz2 \
     -O http://kernel.org/pub/software/scm/git/git-1.5.2.4.tar.bz2.sign
gpg --verify git-1.5.2.4.tar.bz2.sign git-1.5.2.4.tar.bz2
tar xjvf git-1.5.2.4.tar.bz2
cd git-1.5.2.4
make prefix=/usr/local all
make prefix=/usr/local test
echo $?
sudo make prefix=/usr/local install
cd ..

# manpages
curl -O  http://www.kernel.org/pub/software/scm/git/git-manpages-1.5.2.4.tar.bz2 \
     -O http://www.kernel.org/pub/software/scm/git/git-manpages-1.5.2.4.tar.bz2.sign

sudo tar xjv -C /usr/local/share/man -f git-manpages-1.5.2.4.tar.bz2

Configuration

I also had to undertake some of the configuration described in "Git quickstart":

# personalize these with your own name and email address
git config --global user.name "Wincent Colaiuta"
git config --global user.email "win@wincent.com"

# colorize output
git config --global color.status auto
git config --global color.diff auto
git config --global color.branch auto

# shortcut aliases
git config --global alias.st status
git config --global alias.ci commit
git config --global alias.co checkout

# use Apple opendiff (FileMerge) for resolving conflicts
git config --global merge.tool opendiff

# this so I can submit patches using git send-email
git config --global sendemail.smtpserver smtp.example.com
git config --global sendemail.aliasesfile ~/.gitaliases
git config --global sendemail.aliasfiletype mailrc

# shortcut aliases for submitting patches for Git itself
echo "alias git git@vger.kernel.org" >> ~/.gitaliases
echo "alias junio gitster@pobox.com" >> ~/.gitaliases

# turn on new 1.5 features which break backwards compatibility
git config --global core.legacyheaders false
git config --global repack.usedeltabaseoffset true

I added these aliases to my ~/.bash_profile:

# show difference between the HEAD and the index
alias staged="git diff --cached"

# show difference between working tree and the index
alias unstaged="git diff"

# show staged and unstaged changes (what would be committed with "git commit -a")
alias both="git diff HEAD"

I set up a global ignores file:

git config --global core.excludesfile ~/.gitignore
echo ".DS_Store" >> ~/.gitignore

And a basic .gitk file:

cat > ~/.gitk <<EOF
set mainfont {Monaco 10}
set textfont {Monaco 10}
set uifont {Monaco 10}
EOF

And finally appropriate additions to my ~/.ssh/config file, after copying over my_git_private_key from my Tiger partition:

cat >> ~/.ssh/config <<EOF
Host git.example.com
  IdentityFile /Users/wincent/.ssh/my_git_private_key
  HostName git.example.com
  User git
EOF
