   | 12183   | For py3k compat, remove Package.__cmp__() and related cmp()  |
   | zmedico | function call.                                               |

   | 12184   | For py3k compat, avoid using list.sort(cmp).                 |
   | zmedico |                                                              |

   | 12185   | When in --debug mode, make the depgraph call                 |
   | zmedico | self.digraph.debug_print() to display the final digraph      |
   |         | state. This should help when troubleshooting problems with   |
   |         | blockers that don't resolve automatically, by making it      |
   |         | easier to see what pulled in unwanted packages.              |

   | 12186   | Bug #250166 - To avoid accidental regeneration of digests    |
   | zmedico | with the incorrect files (such as partially downloaded       |
   |         | files), trigger the fetch code if the file exists and it's   |
   |         | size doesn't match the current manifest entry. If there      |
   |         | really is a legitimate reason for the digest to change,      |
   |         | `ebuild --force digest` can be used to avoid triggering this |
   |         | code (or else the old digests can be manually removed from   |
   |         | the Manifest).                                               |

   | 12187   | Simplify the code from bug #250166.                          |
   | zmedico |                                                              |

   | 12188   | In digestgen(), don't call fetch for files that already      |
   | zmedico | exist but have invalid zero-size in the manifest.            |

   | 12189   | Bug #250148 - Prevent ebuild.sh subprocess from inheriting   |
   | zmedico | file descriptor 9, since otherwise if a daemon process such  |
   |         | as udevd gets spawned then it can inherit the file           |
   |         | descriptor and hang emerge.                                  |

   | 12190   | When attempting to close fd 9 at the end of the depend       |
   | zmedico | phase, use exec so that it really works.                     |

   | 12191   | When processing output from the "depend" phase, use the      |
   | zmedico | number of lines as a sanity check so that bash's returncode  |
   |         | doesn't have to be trusted.                                  |

   | 12192   | urlparse.urljoin() only works correctly with recognized      |
   | zmedico | protocols and requires the base url to have a trailing       |
   |         | slash, so join PORTAGE_BINHOST manually. Thanks to Lance     |
   |         | Albertson <ramereth@g.o> for reporting.                      |

   | 12193   | When the Binpkg class has fetched a package in --fetchonly   |
   | zmedico | mode, wait until after the package is verified and injected  |
   |         | before returning.                                            |

   | 12194   | Create a BinpkgPrefetcher composite task to handle fetch,    |
   | zmedico | verification, and injection.                                 |

   | 12195   | Verify binary packages even when not in "strict" mode        |
   | zmedico | (normal distfiles are also verified in this case).           |

   | 12196   | Make the Binpkg class handle fetch logging similar to how    |
   | zmedico | EbuildBuild does, directing output to PORTAGE_LOG_FILE       |
   |         | instead of emerge-fetch.log which is only used for           |
   |         | prefetchers now.                                             |

   | 12197   | Make BinpkgVerifier rename files that fail verification,     |
   | zmedico | similar to how distfiles are automatically renamed.          |

   | 12198   | Make Binpkg clean the build dir immediately after locking    |
   | zmedico | it. This ensures that a new PORTAGE_LOG_FILE is created.     |

   | 12199   | For py3k compat, remove Atom.__cmp__() and use str.__lt__()  |
   | zmedico | instead.                                                     |

   | 12200   | Remove ManifestEntry.__cmp__() since it's not needed and     |
   | zmedico | py3k won't use it.                                           |
