An interesting Python function for working with Subversion

This is a function I wrote for working with SVN repositories. It works like os.walk.

import pysvn

"""
Utilities for working with Subversion repositories

"""


def walk (targeturl):
  """
  Walk through an subversion repository.

  """
  dirStack = []
  theEnd = 0
  client = pysvn.Client()
  client.callback_get_login = prompt
  client.callback_notify = notify
  client.callback_get_log_message = logmessage

  ls = client.ls(targeturl, recurse = False)
  files = []
  dirs = []
  for item in ls:
      if item["kind"] == pysvn.node_kind.dir:
          dirStack.append(item)
          dirs.append(endOfPath(item["name"]))
      if item["kind"] == pysvn.node_kind.file:
          files.append(item["name"])
  yield (targeturl, dirs, files)

  while len(dirStack):
      files = []
      dirs = []
      base = dirStack[theEnd]
      del dirStack[theEnd]
    
      currentDir = base["name"]
      ls = client.ls(currentDir, recurse = False)
      for item in ls:
          if item["kind"] == pysvn.node_kind.dir:
              name = endOfPath(item["name"])
              dirs.append(name)
              dirStack.append(item)
          if item["kind"] == pysvn.node_kind.file:
              name = endOfPath(item["name"])
              files.append(name)

      yield (currentDir, dirs, files)


    
  return
