Setup on Arch Linux
===================

For testing aurweb patches before submission, you can use the instructions in
TESTING for testing the web interface only.

Note that you can only do limited testing using the PHP built-in web server.
In particular, the cgit interface will be unusable as well as the ssh+git
interface. For a detailed description on how to setup a full aurweb server,
read the instructions below.

1) Clone the aurweb project:

   $ cd /srv/http/
   $ git clone git://git.archlinux.org/aurweb.git

2) Setup a web server with PHP and MySQL. Configure the web server to redirect
   all URLs to /index.php/foo/bar/. The following block can be used with nginx:

    server {
        listen       80;
        server_name  aur.local aur;

        root   /srv/http/aurweb/web/html;
        index  index.php;

        location ~ ^/[^/]+\.php($|/) {
            fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
            fastcgi_index  index.php;
            fastcgi_split_path_info ^(/[^/]+\.php)(/.*)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO        $fastcgi_path_info;
            include        fastcgi_params;
        }

        location ~ .* {
            rewrite ^/(.*)$ /index.php/$1 last;
        }
    }

3) Copy conf/config.proto to /etc/aurweb/config and adjust the configuration
   (pay attention to disable_http_login, enable_maintenance and aur_location).

4) Create a new MySQL database and a user and import the aurweb SQL schema:

    $ mysql -uaur -p AUR </srv/http/aurweb/schema/aur-schema.sql

5) Install Python modules and dependencies:

    # pacman -S python-mysql-connector python-pygit2 python-srcinfo
    # pacman -S python-bleach python-markdown
    # python3 setup.py install

6) Create a new user:

    # useradd -U -d /srv/http/aurweb -c 'AUR user' aur

7) Initialize the Git repository:

    # mkdir /srv/http/aurweb/aur.git/
    # cd /srv/http/aurweb/aur.git/
    # git init --bare
    # git config --local transfer.hideRefs '^refs/'
    # git config --local --add transfer.hideRefs '!refs/'
    # git config --local --add transfer.hideRefs '!HEAD'
    # ln -s /usr/local/bin/aurweb-git-update hooks/update
    # chown -R aur .

   It is recommended to read doc/git-interface.txt for more information on the
   administration of the package Git repository.

8) Configure sshd(8) for the AUR. Add the following lines at the end of your
   sshd_config(5) and restart the sshd. Note that OpenSSH 6.9 or newer is
   needed!

    Match User aur
        PasswordAuthentication no
        AuthorizedKeysCommand /usr/local/bin/aurweb-git-auth "%t" "%k"
        AuthorizedKeysCommandUser aur
        AcceptEnv AUR_OVERWRITE

9) If you want to enable smart HTTP support with nginx and fcgiwrap, you can
   use the following directives:

    location ~ "^/([a-z0-9][a-z0-9.+_-]*?)(\.git)?/(git-(receive|upload)-pack|HEAD|info/refs|objects/(info/(http-)?alternates|packs)|[0-9a-f]{2}/[0-9a-f]{38}|pack/pack-[0-9a-f]{40}\.(pack|idx))$" {
        fastcgi_pass   unix:/run/fcgiwrap.sock;
        include        fastcgi_params;
        fastcgi_param  SCRIPT_FILENAME /usr/lib/git-core/git-http-backend;
        fastcgi_param  PATH_INFO /aur.git/$3;
        fastcgi_param  GIT_HTTP_EXPORT_ALL "";
        fastcgi_param  GIT_NAMESPACE $1;
        fastcgi_param  GIT_PROJECT_ROOT /srv/http/aurweb/;
    }

   Sample systemd unit files for fcgiwrap can be found under conf/.
