void sbuild::chroot::facet::loopback::chroot_session_setup ( const chroot parent,
const std::string &  session_id,
const std::string &  alias,
const std::string &  user,
bool  root 
)
protectedvirtual

Set up a newly-cloned session chroot.

Parameters
parentthe parent of the cloned chroot.
session_idthe identifier (session_id) for the new session.
aliasused to initially identify the chroot.
userthe user creating the session.
roottrue if the user has root access, otherwise false.

Implements sbuild::chroot::facet::session_setup.

References sbuild::chroot::chroot::get_facet(), get_filename(), and sbuild::chroot::facet::facet::owner.

facet::ptr sbuild::chroot::facet::loopback::clone ( ) const
virtual

Copy the chroot facet.

This is a virtual copy constructor.

Returns
a shared_ptr to the new copy of the chroot facet.

Implements sbuild::chroot::facet::facet.

References loopback().

loopback::ptr sbuild::chroot::facet::loopback::create ( )
static

Create a chroot facet.

Returns
a shared_ptr to the new chroot facet.

References loopback().

void sbuild::chroot::facet::loopback::get_details ( format_detail detail) const
protectedvirtual

Get detailed information about the chroot for output.

Parameters
detailthe details to output to.

Reimplemented from sbuild::chroot::facet::facet.

References sbuild::_(), sbuild::format_detail::add(), filename, and get_filename().

std::string const & sbuild::chroot::facet::loopback::get_filename ( ) const

Get the filename containing the chroot.

Returns
the filename.

+ Here is the caller graph for this function:

void sbuild::chroot::facet::loopback::get_keyfile ( keyfile keyfile) const
protectedvirtual

Copy the chroot properties into a keyfile.

The keyfile group with the name of the chroot will be set; if it already exists, it will be removed before setting it.

Parameters
keyfilethe keyfile to use.

Reimplemented from sbuild::chroot::facet::facet.

References get_filename(), sbuild::chroot::chroot::get_name(), sbuild::chroot::facet::facet::owner, and sbuild::keyfile::set_object_value().

std::string const & sbuild::chroot::facet::loopback::get_name ( ) const
virtual

Get the name of the chroot facet.

Returns
the chroot facet name.

Implements sbuild::chroot::facet::facet.

std::string sbuild::chroot::facet::loopback::get_path ( ) const
virtual

Get the path to the chroot.

This is the absolute path to the root of the chroot, and is typically the same as the mount location and location concatenated together, but is overridden by the chroot type if required.

Returns
the path.

Implements sbuild::chroot::facet::storage.

References sbuild::chroot::chroot::get_facet(), sbuild::chroot::chroot::get_mount_location(), and sbuild::chroot::facet::facet::owner.

void sbuild::chroot::facet::loopback::get_used_keys ( string_list used_keys) const
protectedvirtual

Get a list of the keys used during keyfile parsing.

Returns
a list of key names.

Reimplemented from sbuild::chroot::facet::facet.

void sbuild::chroot::facet::loopback::set_chroot ( chroot chroot,
bool  copy 
)
protectedvirtual

Set containing chroot.

The copy parameter is used to inform the facet if it is new or a copy; this is intended to allow additional facets to only be added if the facet is new, for example, to avoid re-adding removed facets when copying a chroot.

Parameters
chrootthe chroot containing this facet.
copytrue if the facet has been copied, or false if this is a new instance.

Reimplemented from sbuild::chroot::facet::facet.

void sbuild::chroot::facet::loopback::set_filename ( const std::string &  filename)

Set the filename containing the chroot.

Parameters
filenamethe filename.

Referenced by set_keyfile().

+ Here is the caller graph for this function:

void sbuild::chroot::facet::loopback::set_keyfile ( const keyfile keyfile)
protectedvirtual

Set the chroot properties from a keyfile.

The chroot name must have previously been set, so that the correct keyfile group may be determined.

Parameters
keyfilethe keyfile to get the properties from.

Reimplemented from sbuild::chroot::facet::facet.

References sbuild::chroot::chroot::get_name(), sbuild::keyfile::get_object_value(), sbuild::chroot::facet::facet::owner, sbuild::keyfile::PRIORITY_REQUIRED, and set_filename().

void sbuild::chroot::facet::loopback::setup_env ( environment env) const
virtual

Set environment.

Set the environment that the setup scripts will see during execution.

Parameters
envthe environment to set.

Reimplemented from sbuild::chroot::facet::facet.
