   | 13920   | correct pointer, as pointed out by darkside in IRC           |
   | grobian |                                                              |

   | 13921   | Bug #280460 - Fix UnicodeDecodeError in env_update() due to  |
   | zmedico | non-unicode strings from getconfig(). TODO: Make getconfig() |
   |         | return unicode.                                              |

   | 13924   | Fix UnicodeEncodeError in                                    |
   | zmedico | vardbapi._owners_cache._hash_str(), reported by jlec on irc. |

   | 13925   | Fix transposition of CodecInfo streamreader and streamwriter |
   | zmedico | attributes inside _gen_missing_encodings(). This solves      |
   |         | 'TypeError: an integer is required' exceptions from          |
   |         | codecs.open().readlines([sizehint]), triggered when python   |
   |         | is built with USE=build (stage 1). Thanks to Daniel Robbins  |
   |         | for reporting.                                               |

   | 13926   | Do not pass unicode strings into os.walk calls, since it can |
   | zmedico | cause internal os.path.join calls to raise                   |
   |         | UnicodeDecodeError.                                          |

   | 13927   | Remove odd os.getcwd() call used inside main() when          |
   | zmedico | searching for tests.                                         |

   | 13928   | Use realpath to resolve __file__ when searching for test     |
   | zmedico | inside main().                                               |

   | 13929   | Fix broken os.walk call in _post_src_install_uid_fix().      |
   | zmedico |                                                              |
