Constructor. :param tree: The tree that will be transformed, but not necessarily the output tree. :param limbodir: A directory where new files can be stored until they are installed in their proper places :param pb: ignored :param case_sensitive: If True, the target of the transform is case sensitive, not just case preserving.
This is required if apply has not been invoked, but can be invoked even after apply.
This is suitable as a fallback, and when the transform should not be sensitive to the path encoding of the limbo directory.
This means we outsmarted ourselves-- we tried to avoid renaming these files later by creating them with their final names in their final parents. But now the previous name or parent is no longer suitable, so we have to rename them.
Even for trans_ids that have no new contents, we must remove their entries from _limbo_files, because they are now stale.
Parameters | contents | an iterator of strings, all of which will be written to the target destination. |
trans_id | TreeTransform handle | |
mode_id | If not None, force the mode of the target file to match the mode of the object referenced by mode_id. Otherwise, we will try to preserve mode bits of an existing file. | |
sha1 | If the sha1 of this content is already known, pass it in. We can use it to prevent future sha1 computations. | |
See Also | new_file. |
This time is set by the first object to be created.
target is a bytestring. See also new_symlink.
When a directory is about to be removed, its children, if they are not versioned are moved out of the way: they don't have a parent anymore.
Parameters | trans_id | The trans_id of the existing item. |
parent_id | The parent trans_id of the item. |
