Function Documentation

def damn_at.damnfs.path.attach	(		file_id,
			trunk,
			branch = None
	)

Insert a branch of directories on its trunk.

Here is the caller graph for this function:

def damn_at.damnfs.path.expand_path	(		path,
			start_path,
			base_depth
	)

Make a path relative to the given starting path and make the path
atleast base_depth deep by prepending '_' directories.

:param path: :py:class:`string`: the path to expand
:param start_path: :py:class:`damn_at.FileDescription`: the starting path
:param base_depth: :py:class:`int`: how deep the the base file should be
:rtype: :py:class:`string`

Here is the call graph for this function:

Here is the caller graph for this function:

def damn_at.damnfs.path.file_ids_as_tree	(		file_ids,
			start_path
	)

Create a tree like structure using the filenames of the given FileIds.

:param file_ids: :py:func:`list` of :py:class:`damn_at.thrift.generated.damn_types.ttypes.FileId`
:param start_path: :py:class:`string`: the base path
:rtype: :py:class:`dict` {'adir':<>, '<files>':[...]}

Here is the call graph for this function:

def damn_at.damnfs.path.find_path_for_file_id	(		file_ids_tree,
			file_id
	)

Traverse the FileIds tree to construct a path for the given FileId

:param file_ids_tree: :py:class:`dict` {'adir':<>, '<files>':[...]}
:param file_id: :py:class:`damn_at.thrift.generated.damn_types.ttypes.FileId`: the fileId we're looking for
:rtype: :py:class:`string`: the path

def damn_at.damnfs.path.get_files_for_path	(		file_ids_tree,
			path
	)

Traverse the FileIds tree with the given path and return the sub-tree
at that level or the file if a leaf-node.

:param file_ids_tree: :py:class:`dict` {'adir':<>, '<files>':[...]}
:param path: :py:class:`string`: the path
:rtype: :py:class:`dict` {'adir':<>, '<files>':[...]}

def damn_at.damnfs.path.normdirpath

(

path

)

Make a directory path end with /

Here is the caller graph for this function:

def damn_at.damnfs.path.parse_path

(

path

)

Parse a path of /hash/action/my/path returning a tuple of
('hash', 'action', '/my/path') or None values if a shorter path is
given.

:param path: :py:class:`string`: the path
:rtype: :py:func:`tuple`

def damn_at.damnfs.path.path_depth

(

path

)

Give the depth, the number of directories deep, of a path

Here is the caller graph for this function:

def damn_at.damnfs.path.prettify	(		tree,
			indent = 0
	)

Print the file tree structure with proper indentation.
