Part of bzrlib.controldir View In Hierarchy
Formats are placed in a dict by their format string for reference during controldir opening. These should be subclasses of ControlDirFormat for consistency.
Once a format is deprecated, just deprecate the initialize and open methods on the format class. Do not deprecate the object, as the object will be created every system load.
|Class Variables||colocated_branches||Whether this formats supports colocated branches.|
|supports_workingtrees||This control directory can co-exist with a working tree.|
|Method||get_format_description||Return the short description for this format.|
|Method||get_converter||Return the converter to use to convert controldirs needing converts.|
|Method||is_supported||Is this format supported?|
|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.|
|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.|
|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.|
|Method||initialize_on_transport||Initialize a new controldir in the base directory of a Transport.|
|Method||initialize_on_transport_ex||Create this format on transport.|
|Method||network_name||A simple byte string uniquely identifying this format for RPC calls.|
|Method||open||Return an instance of this format for the dir transport points at.|
|Class Method||get_default_format||Return the current default format.|
|Method||supports_transport||Check if this format can be opened over a particular transport.|
|Class Method||_set_default_format||Set default format (for testing behavior of defaults only)|
This returns a bzrlib.controldir.Converter object.
This should return the best upgrader to step this format towards the current default format. In the case of plugins we can/should provide some means for them to extend the range of returnable converters.
|Parameters||format||Optional format to override the default format of the library.|
Supported formats must be openable. Unsupported formats may not support initialization or committing or some other features depending on the reason for not being supported.
|Parameters||allow_unsupported||If true, allow opening formats that are strongly deprecated, and which may have limited functionality.|
|recommend_upgrade||If true (default), warn the user through the ui object that they may wish to upgrade the object.|
These probers will be used before ones registered with register_prober. This gives implementations that decide to the chance to grab it before anything looks at the contents of the format file.
While not deprecated, this method is very specific and its use will lead to many round trips to setup a working environment. See initialize_on_transport_ex for a [nearly] all-in-one method.
Subclasses should typically override initialize_on_transport instead of this method.
The directory to initialize will be created.
|Parameters||force_new_repo||Do not use a shared repository for the target, even if one is available.|
|create_prefix||Create any missing directories leading up to to_transport.|
|use_existing_dir||Use an existing directory if one exists.|
|stacked_on||A url to stack any created branch on, None to follow any target stacking policy.|
|stack_on_pwd||If stack_on is relative, the location it is relative to.|
|repo_format_name||If non-None, a repository will be made-or-found. Should none be found, or if force_new_repo is True the repo_format_name is used to select the format of repository to create.|
|make_working_trees||Control the setting of make_working_trees for a new shared repository when one is made. None to use whatever default the format has.|
|shared_repo||Control whether made repositories are shared or not.|
|vfs_only||If True do not attempt to use a smart server|
|Returns||repo, controldir, require_stacking, repository_policy. repo is None if none was created or found, controldir is always valid. require_stacking is the result of examining the stacked_on parameter and any stacking policy found for the target.|
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.
