git.sr.ht installation

git.sr.ht is the git repository hosting service for the sr.ht network.

Installation

git.sr.ht is a standard sr.ht web service and can be installed through the standard procedure. However, there are several additional steps required.

Repository storage

You will need to set up a directory for repositories to be stored in - we suggest /var/lib/git/. Also configure a git user and assign ownership over /var/lib/git/ to this user. The git.sr.ht package will automatically prepare these for you. If you do not use the package, you must create the user yourself and ensure that the git.sr.ht web application runs as this user.

SSH dispatch

It is necessary to configure git.sr.ht's SSH dispatcher as the system-wide SSH authorization hook. In /etc/ssh/sshd_config, configure git-srht-dispatch like so:

AuthorizedKeysCommand=/usr/bin/git-srht-dispatch "%u" "%h" "%t" "%k"
AuthorizedKeysCommandUser=root

sshd will invoke our dispatcher whenever a connection is made to the server to obtain a list of authorized keys for the connecting user. The default behavior is to read the .ssh/authorized_keys file from that user's HOME directory, but the dispatcher can also dispatch to other authentication tools for other users. This is used to authorize and perform git operations via the git-srht-keys and git-srht-shell. See the [dispatch] section of your git.sr.ht configuration for details on how this works and how to configure it for additional services (e.g. man.sr.ht).

Authorization logs are written to /var/log/git-srht-dispatch and git-srht-shell.

Cronjobs

You must also configure git-srht-periodic to run periodically with your favorite cron daemon. We recommend the following crontab:

*/20 * * * * git-srht-periodic

HTTP(s) Cloning

git.sr.ht does not do this for you - you need to wire it up in nginx. Here's an example config:

location = /authorize {
    proxy_pass http://127.0.0.1:5001;
    proxy_pass_request_body off;
    proxy_set_header Content-Length "";
    proxy_set_header X-Original-URI $request_uri;
}

location ~ ^.*/(HEAD|info/refs|objects/info/.*|git-(upload|receive)-pack).*$ {
    auth_request /authorize;
    root /var/lib/git;
    fastcgi_pass unix:/run/fcgiwrap.sock;
    fastcgi_param SCRIPT_FILENAME /usr/lib/git-core/git-http-backend;
    fastcgi_param PATH_INFO $uri;
    fastcgi_param GIT_PROJECT_ROOT $document_root;
    fastcgi_param GIT_HTTP_EXPORT_ALL "";
    include fastcgi_params;
    gzip off;
}

It's important that you set up the /authorize endpoint to enforce the privacy of private repositories.

If you don't have /run/fcgiwrap.sock on your system, you'll need to install the fcgiwrap package (for instance: apt-get install fcgiwrap). On some systems, the script might be /run/fcgiwrap.socket.
