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.

ParametersttThe TreeTransform orphaning trans_id.
orphan_idThe trans id that should be orphaned.
parent_idThe 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'.
ParameterstreeThe tree to convert wt into a copy of
wtThe working tree that files will be placed into
accelerator_treeA 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.
hardlinkIf true, hard-link files to accelerator_tree, where possible. accelerator_tree must implement abspath, i.e. be a working tree.
delta_from_treeIf 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.
Parametersfilter_tree_paththe 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)))

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):

def conflict_pass(tt, conflicts, path_tree=None):
Resolve some classes of conflicts.
ParametersttThe transform to resolve conflicts in
conflictsThe conflicts to resolve
path_treeA 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):
Undocumented
