Bzr dir format 4.

This format is a combined format for working tree, branch and repository.
It has:
 - Format 1 working trees [always]
 - Format 4 branches [always]
 - Format 4 repositories [always]

This format is deprecated: it indexes texts using a text it which is
removed in format 5; write support for this format has been removed.
Method __eq__ Undocumented

Method get_converter See BzrDirFormat.get_converter().
Method initialize_on_transport Format 4 branches cannot be created.
Method is_supported Format 4 is not supported.
Method network_name A simple byte string uniquely identifying this format for RPC calls.

Inherited from BzrDirFormat:

Method initialize_on_transport_ex Create this format on transport.
Method open Return an instance of this format for the dir transport points at.
Method supports_transport Check if this format can be opened over a particular transport.
Method _initialize_on_transport_vfs Initialize a new bzrdir using VFS calls.
Method _supply_sub_formats_to Give other_format the same values for sub formats as this has.

Inherited from ControlDirFormat (via BzrDirFormat):

Method is_initializable Whether new control directories of this format can be initialized.
Method check_support_status Give an error or warning on old formats.
Method same_model Undocumented
Class Method register_format Register a format that does not use '.bzr' for its control dir.
Class Method register_prober Register a prober that can look for a control dir.
Class Method unregister_prober Unregister a prober.
Class Method register_server_prober Register a control format prober for client-server environments.
Method __str__ Undocumented
Class Method known_formats Return all the known formats.
Class Method find_format Return the format present at transport.
Method initialize Create a control dir at this url and return an opened copy.
Class Method get_default_format Return the current default format.
Class Method _set_default_format Set default format (for testing behavior of defaults only)

def get_format_string(self):
See BzrDirFormat.get_format_string().
def get_format_description(self):
See BzrDirFormat.get_format_description().
def get_converter(self, format=None):
See BzrDirFormat.get_converter().
def initialize_on_transport(self, transport):
Format 4 branches cannot be created.
def is_supported(self):
Format 4 is not supported.

It is not supported because the model changed from 4 to 5 and the conversion logic is expensive - so doing it on the fly was not feasible.

def network_name(self):
A simple byte string uniquely identifying this format for RPC calls.

Bzr control formats use this disk format string to identify the format over the wire. Its possible that other control formats have more complex detection requirements, so we permit them to use any unique and immutable string they desire.

def _open(self, transport):
See BzrDirFormat._open.
def __return_repository_format(self):
Circular import protection.
