Detailed Description

A chroot stored in a file for loopback mounting.

The file will be mounted on demand.


Constructor & Destructor Documentation

chroot_loopback::chroot_loopback (  )  [protected]

The constructor.

Referenced by clone().

chroot_loopback::~chroot_loopback (  )  [virtual]

The destructor.


Member Function Documentation

sbuild::chroot::ptr chroot_loopback::clone (  )  const [virtual]

Copy the chroot.

This is a virtual copy constructor.

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

Implements sbuild::chroot.

References chroot_loopback().

std::string const & chroot_loopback::get_file (  )  const

Get the file containing the chroot.

Returns:
the file.

References file.

Referenced by get_details(), get_keyfile(), and setup_env().

void chroot_loopback::set_file ( std::string const &  file  ) 

Set the file containing the chroot.

Parameters:
file the file.

References sbuild::chroot::FILE_ABS, and sbuild::is_absname().

Referenced by set_keyfile().

std::string const & chroot_loopback::get_mount_device (  )  const [virtual]

Get the mount device of the chroot.

Returns:
the device.

Implements sbuild::chroot_mountable.

References file.

std::string const & chroot_loopback::get_chroot_type (  )  const [virtual]

Get the type of the chroot.

Returns:
the chroot type.

Implements sbuild::chroot.

void chroot_loopback::setup_env ( environment env  )  [virtual]

Set environment.

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

Parameters:
env the environment to set.

Reimplemented from sbuild::chroot_mountable.

References sbuild::environment::add(), get_file(), sbuild::chroot_mountable::setup_env(), and sbuild::chroot::setup_env().

sbuild::chroot::session_flags chroot_loopback::get_session_flags (  )  const [virtual]

Get the session flags of the chroot.

These determine how the Session controlling the chroot will operate.

Returns:
the session flags.

Reimplemented from sbuild::chroot_mountable.

References sbuild::chroot_mountable::get_session_flags(), and sbuild::chroot::SESSION_NOFLAGS.

void chroot_loopback::setup_lock ( chroot::setup_type  type,
bool  lock,
int  status 
) [protected, virtual]

Unlock a chroot during setup.

The locking technique (if any) may vary depending upon the chroot type and setup stage. For example, during creation of an LVM snapshot a block device might require locking, but afterwards this will change to the new block device.

An error will be thrown on failure.

Parameters:
type the type of setup being performed
lock true to lock, false to unlock
status the exit status of the setup commands (0 for success, nonzero for failure).

Implements sbuild::chroot.

References sbuild::stat::check_mode(), file, sbuild::chroot::FILE_NOTREG, sbuild::chroot::FILE_OWNER, sbuild::chroot::FILE_PERMS, sbuild::stat::is_regular(), sbuild::stat::PERM_OTHER_WRITE, sbuild::chroot::SETUP_START, and sbuild::stat::uid().

void chroot_loopback::get_details ( format_detail detail  )  const [protected, virtual]

Get detailed information about the chroot for output.

Parameters:
detail the details to output to.

Reimplemented from sbuild::chroot_mountable.

References sbuild::format_detail::add(), file, sbuild::chroot_mountable::get_details(), sbuild::chroot::get_details(), and get_file().

void chroot_loopback::get_keyfile ( keyfile keyfile  )  const [protected, virtual]

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:
keyfile the keyfile to use.

Reimplemented from sbuild::chroot_mountable.

References get_file(), sbuild::chroot_mountable::get_keyfile(), sbuild::chroot::get_keyfile(), sbuild::chroot::get_name(), and sbuild::basic_keyfile< K, P >::set_object_value().

void chroot_loopback::set_keyfile ( keyfile const &  keyfile,
string_list used_keys 
) [protected, virtual]

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:
keyfile the keyfile to get the properties from.
used_keys a list of the keys used will be set.

Reimplemented from sbuild::chroot_mountable.

References sbuild::chroot::get_name(), sbuild::basic_keyfile< K, P >::get_object_value(), sbuild::keyfile_base::PRIORITY_REQUIRED, set_file(), sbuild::chroot_mountable::set_keyfile(), and sbuild::chroot::set_keyfile().
