bzrlib.transform : API documentation

def unique_add(map, key, value):

Undocumented

def move_orphan(tt, orphan_id, parent_id):

See TreeTransformBase.new_orphan.

This creates a new orphan in the bzr-orphans dir at the root of the TreeTransform.

Parameters	tt	The TreeTransform orphaning `trans_id`.
	orphan_id	The trans id that should be orphaned.
	parent_id	The orphan parent trans id.

def refuse_orphan(tt, orphan_id, parent_id):

See TreeTransformBase.new_orphan.

This refuses to create orphan, letting the caller handle the conflict.

def joinpath(parent, child):

Join tree-relative paths, handling the tree root specially

def topology_sorted_ids(tree):

Determine the topological order of the ids in a tree

def build_tree(tree, wt, accelerator_tree=None, hardlink=False, delta_from_tree=False):

Create working tree for a branch, using a TreeTransform.

This function should be used on empty trees, having a tree root at most. (see merge and revert functionality for working with existing trees)

Existing files are handled like so:

Existing bzrdirs take precedence over creating new items. They are created as '%s.diverted' % name.
Otherwise, if the content on disk matches the content we are building, it is silently replaced.
Otherwise, conflict resolution will move the old file to 'oldname.moved'.

Parameters	tree	The tree to convert wt into a copy of
	wt	The working tree that files will be placed into
	accelerator_tree	A tree which can be used for retrieving file contents more quickly than tree itself, i.e. a workingtree. tree will be used for cases where accelerator_tree's content is different.
	hardlink	If true, hard-link files to accelerator_tree, where possible. accelerator_tree must implement abspath, i.e. be a working tree.
	delta_from_tree	If true, build_tree may use the input Tree to generate the inventory delta.

def _build_tree(tree, wt, accelerator_tree, hardlink, delta_from_tree):

See build_tree.

def _create_files(tt, tree, desired_files, pb, offset, accelerator_tree, hardlink):

Undocumented

def _reparent_children(tt, old_parent, new_parent):

Undocumented

def _reparent_transform_children(tt, old_parent, new_parent):

Undocumented

def _content_match(tree, entry, file_id, kind, target_path):

Undocumented

def resolve_checkout(tt, conflicts, divert):

Undocumented

def new_by_entry(tt, entry, parent_id, tree):

Create a new file according to its inventory entry

def create_from_tree(tt, trans_id, tree, file_id, bytes=None, filter_tree_path=None):

Create new file contents according to tree contents.

Parameters filter_tree_path the tree path to use to lookup content filters to apply to the bytes output in the working tree. This only applies if the working tree supports content filtering.

def create_entry_executability(tt, entry, trans_id):

Set the executability of a trans_id according to an inventory entry

@deprecated_function(deprecated_in((2, 3, 0)))
def get_backup_name(entry, by_parent, parent_trans_id, tt):

Undocumented

@deprecated_function(deprecated_in((2, 3, 0)))
def _get_backup_name(name, by_parent, parent_trans_id, tt):

Produce a backup-style name that appears to be available

def revert(working_tree, target_tree, filenames, backups=False, pb=None, change_reporter=None):

Revert a working tree's contents to those of a target tree.

def _prepare_revert_transform(working_tree, target_tree, tt, filenames, backups, pp, basis_tree=None, merge_modified=None):

Undocumented

def _alter_files(working_tree, target_tree, tt, pb, specific_files, backups, merge_modified, basis_tree=None):

Undocumented

def resolve_conflicts(tt, pb=None, pass_func=None):

Make many conflict-resolution attempts, but die if they fail

def conflict_pass(tt, conflicts, path_tree=None):

Resolve some classes of conflicts.

Parameters	tt	The transform to resolve conflicts in
	conflicts	The conflicts to resolve
	path_tree	A Tree to get supplemental paths from

def cook_conflicts(raw_conflicts, tt):

Generate a list of cooked conflicts, sorted by file path

def iter_cook_conflicts(raw_conflicts, tt):
