Git and Gitweb

	Update Needed

NOTE: There is a one-click app currently in ALPHA being tested.

Git is a free & open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Every Git clone is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server. Branching and merging are fast and easy to do. Coupled with Gitweb, provides a web interface for browsing your project.

This tutorial will show you how to install, create a repo, and browse that repo on your HDA.

NOTE: Tested on Fedora 14.

Setup

Create web app (Advanced Settings must be enabled on HDA)

From the Dashboard main page, select Apps at the top.
Choose Webapps
Select New Web App button at the bottom
Enter gitweb for the Name (ensure the path reflects the name correctly)
Choose Create
Open a terminal as root user and do the following:
Install dependencies
```
yum -y install git git-daemon gitweb
```

Look for the ####-gitweb.conf in /etc/httpd/conf.d (#### is some number, i.e. 1000) file and open it in your favorite editor. Add text after ServerAlias line

Text=Alias /git /var/hda/web-apps/gitweb/html
RewriteEngine On
RewriteRule ^git$ git/ [R]
DirectoryIndex gitweb.cgi
SetEnv GITWEB_CONFIG "/etc/gitweb.conf"
AddHandler cgi-script .cgi

Create web page to browse repository

cd /var/hda/web-apps/gitweb
echo '<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<head>
<title>Your Page Title</title>
<meta http-equiv="REFRESH" content="0;url=http://gitweb/git/"></HEAD>
<BODY>
Optional page text here.
</BODY>
</HTML>' > html/index.html
chown apache.users html/index.html

Add user

useradd -U -d /var/cache/git -s /usr/libexec/git-core/git-shell git

Set directory permissions

cd /var/cache
chown -R git:git git
chmod 755 git/

Create /etc/init.d/git file and add the following

#!/bin/sh
#
#   Startup/shutdown script for Git Daemon
#
#   Linux chkconfig stuff:
#
#   chkconfig: 345 56 10
#   description: Startup/shutdown script for Git Daemon
#
. /etc/init.d/functions
 
DAEMON=/usr/libexec/git-core/git-daemon
ARGS='--base-path=/var/cache/git --detach --syslog --export-all --user=git --group=git'
 
prog=git-daemon
 
start () {
 echo -n $"Starting $prog: "
 
 # start daemon
 daemon $DAEMON $ARGS
 RETVAL=$?
 echo
 [ $RETVAL = 0 ] && touch /var/lock/git-daemon
 return $RETVAL
}
 
stop () {
 # stop daemon
 echo -n $"Stopping $prog: "
 killproc $DAEMON
 RETVAL=$?
 echo
 [ $RETVAL = 0 ] && rm -f /var/lock/git-daemon
}
 
restart() {
 stop
 start
}
 
case $1 in
 start)
 start
 ;;
 stop)
 stop
 ;;
 restart)
 restart
 ;;
 status)
 status $DAEMON
 RETVAL=$?
 ;;
 *)
 
 echo $"Usage: $prog {start|stop|restart|status}"
 exit 3
esac
 
exit $RETVAL

Set init script to run

chmod 755 /etc/init.d/git;
/etc/init.d/git start
/sbin/chkconfig git on

Set User information (change user.name and user.email accordingly)

git config --global user.name "MyHDA"
git config --global user.email myhda@localhost

Create temporary repository

cd /var/cache/git/
git init test
cd test

Add test file and a short description

echo 'test' > README
git add README
git commit -a -m "initial README file"

Create local repository

cd /var/cache/git/
git clone test test.git
cd test.git
git push origin master

Edit /var/cache/git/test/.git/config and add the following at the bottom (change MyHDA as desired)
```
[gitweb]
       owner = MyHDA
```

Add to bottom of /etc/gitweb.conf file

$feature{'blame'}{'default'} = [undef];
$feature{'pickaxe'}{'default'} = [undef];
$feature{'search'}{'default'} = [undef];
$feature{'grep'}{'default'} = 1;
$feature{'snapshot'}{'default'} = ['tgz', 'gzip', 'zip'];
$feature{'snapshot'}{'override'} = 1;
$site_name = "HDA Git";
$projectroot = '/var/cache/git/';
$projects_list_description_width = 50;
$git_temp = "/tmp";
$home_text = "indextext.html";
$site_footer = "indexfooter.html";
$projects_list = $projectroot;
$home_link_str = "http://gitweb / git ";
$stylesheet = "/git/static/gitweb.css";
$logo = "/git/static/git-logo.png";
$favicon = "/git/static/git-favicon.png";
$feature{'pathinfo'}{'default'} = [1];
$my_uri = "http://gitweb/git/";
$home_link = "http://gitweb/git/;"

Copy web files and set permissions

d /var/hda/web-apps/gitweb
cp -r /var/www/git/* html
chown -R apache:users html/

Update local repository description

cd /var/cache/git
sed -i '1d' test.git/.git/description
echo 'Test Repo' >> test.git/.git/description

Edit /etc/httpd/conf.d/git.conf and replace with this text

<Directory /var/hda/web-apps/gitweb/html>     
       RewriteEngine On
       RewriteBase /git/
       RewriteRule ^$ gitweb.cgi  [L]
       RewriteCond %{REQUEST_FILENAME} !-f
       RewriteCond %{REQUEST_FILENAME} !-d
       RewriteRule (.*) gitweb.cgi/$1  [QSA,L]
</Directory>

Update permissions, remove temporary repository, and restart web server

chown -R git.git /var/cache/git
rm -rf /var/cache/git/test
/etc/init.d/httpd restart

Complete

That is it. Navigate to http://gitweb/git to browse the newly created repository.

Optional

You can add the Amahi repo by doing the following:

cd /var/cache/git
git clone git://git.amahi.org/amahi.git
