## Basic settings

# Name of the service
our $name = "GiroccoEx";

# Nickname of the service (undef for initial part of $name upto first '.')
our $nickname = undef;

# Title of the service (as shown in gitweb)
our $title = "Example Girocco Hosting";

# Path to the Git binary to use (you MUST set this, even if to /usr/bin/git!)
our $git_bin = '/usr/bin/git';

# E-mail of the site admin

## Feature knobs

# Enable mirroring mode if true
our $mirror = 1;

# Enable push mode if true
our $push = 1;

# Enable user management if true; this means the interface for registering
# user accounts and uploading SSH keys. This implies full chroot.
our $manage_users = 1;

# Enable the special 'mob' user if set to 'mob'
our $mob = "mob";

# Let users set admin passwords; if false, all password inputs are assumed empty.
# This will make new projects use empty passwords and all operations on them
# unrestricted, but you will be able to do no operations on previously created
# projects you have set a password on.
our $project_passwords = 1;

# How to determine project owner; 'email' adds a form item asking for their
# email contact, 'source' takes realname of owner of source repository if it
# is a local path (and empty string otherwise). 'source' is suitable in case
# the site operates only as mirror of purely local-filesystem repositories.
our $project_owners = 'email';

# Which project fields to make editable, out of 'shortdesc', 'homepage',
# 'README', 'notifymail', 'notifyjson', 'notifycia'. (This is currently
# soft restriction - form fields aren't used, but manually injected values
# *are* used. Submit a patch if that's an issue for you.)

# Git URL of the repository collection (undef if N/A)
# (You need to set up git-daemon on your system, and Girocco will not
# do this particular thing for you.)

# Pushy URL of the repository collection (undef if N/A)
our $pushurl = "ssh://repo.or.cz/srv/git";

# You can customize the gitweb interface widely by editing
# gitweb/gitweb_config.perl


## Permission settings

# Note that if you are going to need the fixupd daemon running,
# ($chrooted and $permission_control eq 'Group'), you need to update
# the settings in fixupd/fixupd.sh as well.

# Girocco needs some way to manipulate write permissions to various parts of
# all repositories; this concerns three entities:
# - www-data: the web interface needs to be able to rewrite few files within
# the repository
# - repo: a user designated for cronjobs; handles mirroring and repacking;
# this one is optional if not $mirror
# - others: the designated users that are supposed to be able to push; they
# may have account either within chroot, or outside of it

# There are several ways how to use Girocco based on a combination of the
# following settings.

# (Non-chroot) UNIX user the CGI scripts run on; note that if some non-related
# untrusted CGI scripts run on this account too, that can be a big security
# problem and you'll probably need to set up suexec (poor you).
our $cgi_user = 'www-data';

# (Non-chroot) UNIX user performing mirroring jobs; this is the user who
# should run all the daemons and cronjobs (except the fixupd) and
# the user who should be running make install (if not root).
our $mirror_user = 'repo';

# (Non-chroot) UNIX group owning the repositories by default; it owns whole
# mirror repositories and at least web-writable metadata of push repositories.
# If you undefine this, all the data will become WORLD-WRITABLE.
# Both $cgi_user and $mirror_user should be members of this group!
our $owning_group = 'repo';

# Whether to use chroot jail for pushing; this must be always the same
# as $manage_users.
# TODO: Gitosis support for $manage_users and not $chrooted?
our $chrooted = $manage_users;

# How to control permissions of push-writable data in push repositories:
# * 'Group' for the traditional model: The $chroot/etc/group project database
#   file is used as the UNIX group(5) file; the directories have gid appropriate
#   for the particular repository and are group-writable. This works only if
#   $chrooted so that users are put in the proper groups on login. This requires
#   you also to set up the fixupd/fixupd.sh daemon for root.
# * 'ACL' for a model based on POSIX ACL: The directories are coupled with ACLs
#   listing the users with push permissions. This works for both chroot and
#   non-chroot setups, however it requires ACL support within the filesystem.
#   This option is BASICALLY UNTESTED, too. And UNIMPLEMENTED. :-)
# * 'Hooks' for a relaxed model: The directories are world-writable and push
#   permission control is purely hook-driven. This is INSECURE and works only
#   when you trust all your users; on the other hand, the attack vectors are
#   mostly just DoS or fully-traceable tinkering.
our $permission_control = 'Group';

# Path to named pipe for fixing up project permissions
# Will be read by fixupd.sh
our $fixup_queue = '/var/tmp/fixup.fifo';

# Couple of sanity checks
