# Setting up source hosting


## Special strings

NB! This documentation includes the following special strings
used e.g. when generating a documentation website:

feature_root: /usr/local/share/redpill/source-hosting
redpill_root: /usr/local/share/redpill

gitshellhost: git.example.org


## Prerequisites

All actions are done on the server git.example.org,
except collecting your SSH public key.

Gitolite service need to know the public SSH key of its administrator.
You can let it ask during install,
but it may be more convenient to preconfigure that information instead.

**On your local host**,
print your SSH public key
e.g. with this command
**from your personal system**
(adapt to replace ed25519 if your SSH keypair use a different algorithm):

	cat ~/.ssh/id_ed25519.pub

**On the server git.example.org**,
preconfigure git user
with above public key (the whole line without newline) as $YOURKEY,
and install needed packages:

	echo gitolite3 gitolite3/adminkey select "$YOURKEY" | sudo debconf-set-selections
	echo gitolite3 gitolite3/gituser select git | sudo debconf-set-selections
	sudo apt install gitolite3 myrepos git-daemon-sysvinit cgit cmark highlight

Silence noisy git warnings about migrating to non-oppressive language:

	sudo -u git git config --global init.defaultBranch main


## Enable hook

Clone the redpill feature project for source-hosting
and register with myrepos (to ease later update):

	sudo mkdir --parents /usr/local/share/redpill
	cd /usr/local/share/redpill
	sudo git clone https://source.redpill.dk/source-hosting.git
	cd source-hosting
	sudo mr reg

Edit the file `/etc/gitolite3/gitolite.rc`
to have `LOCAL_CODE` point into the project cloned above,
i.e. the line should look like this:

	LOCAL_CODE =>  "/usr/local/share/redpill/source-hosting/lib/gitolite3",

Refresh gitolite setup
by running this command:

	sudo -u git gitolite setup


### Web export

When some git project need to be exported to a website,
a base directory should first be prepared.

Grant access for gitolite to write below /var/www
with these commands:

	sudo mkdir /var/www/gitolite3
	sudo chown git:www-data /var/www/gitolite3


## Configure web access

Adapt the file `/etc/default/git-daemon`:

	GIT_DAEMON_ENABLE=true
	GIT_DAEMON_USER=gitdaemon
	GIT_DAEMON_BASE_PATH=/srv/git
	GIT_DAEMON_DIRECTORY=/srv/git/source.example.org
	
	# Additional options that are passed to the Daemon.
	GIT_DAEMON_OPTIONS="--interpolated-path=/srv/git/%H/%D --user-path=public_git --export-all"

Adapt the file `/etc/cgitrc`:

	css=/cgit-css/cgit.css
	logo=/cgit-css/cgit.png
	
	include=/usr/local/share/redpill/source-hosting/etc/cgitrc
