Subject: Setting up a git repository which can be pushed into and pulled from over HTTP.
Date: Thu, 10 Aug 2006 22:00:26 +0200
Since Apache is one of those packages people like to compile
themselves while others prefer the bureaucrat's dream Debian, it is
impossible to give guidelines which will work for everyone. Just send
some feedback to the mailing list at git@vger.kernel.org to get this
document tailored to your favorite distro.
What's needed:
- Have an Apache web-server
On Debian:
$ apt-get install apache2
To get apache2 by default started,
edit /etc/default/apache2 and set NO_START=0
- can edit the configuration of it.
This could be found under /etc/httpd, or refer to your Apache documentation.
On Debian: this means being able to edit files under /etc/apache2
- can restart it.
'apachectl --graceful' might do. If it doesn't, just stop and
restart apache. Be warning that active connections to your server
might be aborted by this.
On Debian:
$ /etc/init.d/apache2 restart
or
$ /etc/init.d/apache2 force-reload
(which seems to do the same)
This adds symlinks from the /etc/apache2/mods-enabled to
/etc/apache2/mods-available.
- have permissions to chown a directory
- have git installed at the server _and_ client
In effect, this probably means you're going to be root.
Step 1: setup a bare GIT repository
-----------------------------------
At the time of writing, git-http-push cannot remotely create a GIT
repository. So we have to do that at the server side with git. Another
option would be to generate an empty repository at the client and copy
it to the server with WebDAV. But then you're probably the first to
try that out :)
Create the directory under the DocumentRoot of the directories served
by Apache. As an example we take /usr/local/apache2, but try "grep
DocumentRoot /where/ever/httpd.conf" to find your root:
$ cd /usr/local/apache/htdocs
$ mkdir my-new-repo.git
On Debian:
$ cd /var/www
$ mkdir my-new-repo.git
Initialize a bare repository
$ cd my-new-repo.git
$ git --bare init-db
Change the ownership to your web-server's credentials. Use "grep ^User
httpd.conf" and "grep ^Group httpd.conf" to find out:
$ chown -R www.www .
On Debian:
$ chown -R www-data.www-data .
If you do not know which user Apache runs as, you can alternatively do
a "chmod -R a+w .", inspect the files which are created later on, and
set the permissions appropriately.
Restart apache2, and check whether http://server/my-new-repo.git gives
a directory listing. If not, check whether apache started up
successfully.
Step 2: enable DAV on this repository
-------------------------------------
First make sure the dav_module is loaded. For this, insert in httpd.conf:
LoadModule dav_module libexec/httpd/libdav.so
AddModule mod_dav.c
Also make sure that this line exists which is the file used for
locking DAV operations:
DAVLockDB "/usr/local/apache2/temp/DAV.lock"
On Debian these steps can be performed with:
Enable the dav and dav_fs modules of apache:
$ a2enmod dav_fs
(just to be sure. dav_fs might be unneeded, I don't know)
$ a2enmod dav
The DAV lock is located in /etc/apache2/mods-available/dav_fs.conf:
DAVLockDB /var/lock/apache2/DAVLock
Of course, it can point somewhere else, but the string is actually just a
prefix in some Apache configurations, and therefore the _directory_ has to
be writable by the user Apache runs as.
Then, add something like this to your httpd.conf
<Location /my-new-repo.git>
DAV on
AuthType Basic
AuthName "Git"
AuthUserFile /usr/local/apache2/conf/passwd.git
Require valid-user
</Location>
On Debian:
Create (or add to) /etc/apache2/conf.d/git.conf :
<Location /my-new-repo.git>
DAV on
AuthType Basic
AuthName "Git"
AuthUserFile /etc/apache2/passwd.git
Require valid-user
</Location>
Debian automatically reads all files under /etc/apach2/conf.d.
The password file can be somewhere else, but it has to be readable by
Apache and preferably not readable by the world.
Create this file by
$ htpasswd -c /usr/local/apache2/conf/passwd.git <user>
On Debian:
$ htpasswd -c /etc/apache2/passwd.git <user>
You will be asked a password, and the file is created. Subsequent calls
to htpasswd should omit the '-c' option, since you want to append to the
existing file.
You need to restart Apache.
Now go to http://<username>@<servername>/my-new-repo.git in your
browser to check whether it asks for a password and accepts the right
password.
On Debian:
To test the WebDAV part, do:
$ apt-get install litmus
$ litmus http://<servername>/my-new-repo.git <username> <password>
Most tests should pass.
A command line tool to test WebDAV is cadaver.
If you're into Windows, from XP onwards Internet Explorer supports
WebDAV. For this, do Internet Explorer -> Open Location ->
http://<servername>/my-new-repo.git [x] Open as webfolder -> login .
Step 3: setup the client
------------------------
Make sure that you have HTTP support, i.e. your git was built with curl.
The easiest way to check is to look for the executable 'git-http-push'.
Then, add the following to your $HOME/.netrc (you can do without, but will be
asked to input your password a _lot_ of times):
machine <servername>
login <username>
password <password>
...and set permissions:
chmod 600 ~/.netrc
If you want to access the web-server by its IP, you have to type that in,
instead of the server name.
To check whether all is OK, do:
curl --netrc --location -v http://<username>@<servername>/my-new-repo.git/
...this should give a directory listing in HTML of /var/www/my-new-repo.git .
Now, add the remote in your existing repository which contains the project
you want to export:
$ git-repo-config remote.upload.url \
http://<username>@<servername>/my-new-repo.git/
It is important to put the last '/'; Without it, the server will send
a redirect which git-http-push does not (yet) understand, and git-http-push
will repeat the request infinitely.
Step 4: make the initial push
-----------------------------
From your client repository, do
$ git push upload master
This pushes branch 'master' (which is assumed to be the branch you
want to export) to repository called 'upload', which we previously
defined with git-repo-config.
Troubleshooting:
----------------
If git-http-push says
Error: no DAV locking support on remote repo http://...
then it means the web-server did not accept your authentication. Make sure
that the user name and password matches in httpd.conf, .netrc and the URL
you are uploading to.
If git-http-push shows you an error (22/502) when trying to MOVE a blob,
it means that your web-server somehow does not recognize its name in the
request; This can happen when you start Apache, but then disable the
network interface. A simple restart of Apache helps.
Errors like (22/502) are of format (curl error code/http error
code). So (22/404) means something like 'not found' at the server.
Reading /usr/local/apache2/logs/error_log is often helpful.
On Debian: Read /var/log/apache2/error.log instead.

From the git version 1.4.0 gitweb is bundled with git.
Any comment/question/concern to:
How to configure gitweb for your local system:
You can specify the following configuration variables when building GIT:
* GITWEB_SITENAME
Shown in the title of all generated pages, defaults to the servers name.
* GITWEB_PROJECTROOT
The root directory for all projects shown by gitweb.
* GITWEB_LIST
points to a directory to scan for projects (defaults to project root)
or to a file for explicit listing of projects.
* GITWEB_HOMETEXT
points to an .html file which is included on the gitweb project
overview page.
* GITWEB_CSS
Points to the location where you put gitweb.css on your web server.
* GITWEB_LOGO
Points to the location where you put git-logo.png on your web server.
* GITWEB_CONFIG
This file will be loaded using 'require'. If the environment
$GITWEB_CONFIG is set when gitweb.cgi is executed the file in the
environment variable will be loaded instead of the file
specified when gitweb.cgi was created.
