def apply_txdelta_window(sbuf, window):

Apply a txdelta window to a buffer.

Parameters	sbuf	Source buffer (as bytestring)
	window	(sview_offset, sview_len, tview_len, src_ops, ops, new_data)
	sview_offset	Offset of the source view
	sview_len	Length of the source view
	tview_len	Target view length
	src_ops	Operations to apply to sview
	ops	Ops to apply
	new_data	Buffer with possible new data
Returns	Target buffer

def apply_txdelta_handler_chunks(source_chunks, target_chunks):

Return a function that can be called repeatedly with txdelta windows.

Parameters	sbuf	Source buffer
	target_stream	Target stream

def apply_txdelta_handler(sbuf, target_stream):

Return a function that can be called repeatedly with txdelta windows.

Parameters	sbuf	Source buffer
	target_stream	Target stream

def txdelta_apply_ops(src_ops, ops, new_data, sview):

Apply txdelta operations to a source view.

Parameters	src_ops	Source operations, ignored.
	ops	List of operations (action, offset, length).
	new_data	Buffer to fetch fragments with new data from
	sview	Source data
Returns	Result data

def send_stream(stream, handler, block_size=DELTA_WINDOW_SIZE):

Parameters	diff_params	(action, offset, length)
	action	Action
	offset	Offset
	length	Length
Returns	encoded text

def unpack_svndiff_instruction(text):

Unpack a SVN diff instruction

Parameters	text	Text to parse
Returns	tuple with operation, remaining text
