| 2910 | 68 section "ConfigParser -- Configuration file parser": |

| 70 The configuration file consists of sections, led by a "[section]" header | |

| 72 newline with leading whitespace. Note that leading whitespace is removed | |
| 73 from values. The optional values can contain format strings which | |
| 74 refer to other values in the same section. Lines beginning with "#" or ";" | |
| 75 are ignored and may be used to provide comments. | |

| 182 be either absolute or relative to the directory containig this config file. | |
| 183 | |
| 184 filename -- default *blank* | |
| 185 Log file name for minimal logging facility built into Roundup. If no file | |

| 207 If username is not empty, password (below) MUST be set! | |
| 208 | |

| 216 Allowed values: ``yes``, ``no`` | |
| 217 | |
| 218 tls_keyfile -- default *blank* | |
| 219 If TLS is used, you may set this option to the name of a PEM formatted | |
| 220 file that contains your private key. The path may be either absolute or | |
| 221 relative to the directory containig this config file. | |
| 222 | |

| 226 to the directory containig this config file. | |
| 227 | |
| 228 charset -- utf-8 | |
| 229 Character set to encode email headers with. We use utf-8 by default, as | |
| 230 it's the most flexible. Some mail readers (eg. Eudora) can't cope with | |
| 231 that, so you might need to specify a more limited character set | |
| 232 (eg. iso-8859-1). | |
| 233 | |
| 234 debug -- default *blank* | |
| 235 Setting this option makes Roundup to write all outgoing email messages | |
| 236 to this file *instead* of sending them. This option has the same effect | |
| 237 as environment variable SENDMAILDEBUG. Environment variable takes | |
| 238 precedence. The path may be either absolute or relative to the directory | |
| 239 containig this config file. | |
| 240 | |

| 247 Allowed values: ``yes``, ``no`` | |
| 248 | |
| 249 leave_body_unchanged -- ``no`` | |

395 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 396 |
| 397 **Change the type of a property** | |
| 398 Property types must *never* be changed - the database simply doesn't take | |
| 399 this kind of action into account. Note that you can't just remove a | |
| 400 property and re-add it as a new type either. If you wanted to make the | |
| 401 assignedto property a Multilink, you'd need to create a new property | |
| 402 assignedto_list and remove the old assignedto property. | |
| 403 | |
| 404 | |
| 405 What you can do to the schema | |
| 406 ----------------------------- | |
| 407 | |
| 408 Your schema may be changed at any time before or after the tracker has been | |
| 409 initialised (or used). You may: | |
| 410 | |
| 411 **Add new properties to classes, or add whole new classes** | |
| 412 This is painless and easy to do - there are generally no repurcussions | |
| 413 from adding new information to a tracker's schema. | |
| 414 | |
| 415 **Remove properties** | |
| 416 Removing properties is a little more tricky - you need to make sure that | |
| 417 the property is no longer used in the `web interface`_ *or* by the | |
| 418 detectors_. | |

| 660 Detector API | |
| 661 ------------ | |
| 662 | |
| 663 Auditors are called with the arguments:: | |
| 664 | |
| 665 audit(db, cl, itemid, newdata) | |
| 666 | |
| 667 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 668 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 669 property names to values. | |
| 670 | |
| 671 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 672 newdata contains all of the initial property values with which the item | |
| 673 is about to be created. | |
| 674 | |
| 675 For a ``set()`` operation, newdata contains only the names and values of | |
| 676 properties that are about to be changed. | |
| 677 | |
| 678 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 679 | |
| 680 Reactors are called with the arguments:: | |
| 681 | |
| 682 react(db, cl, itemid, olddata) | |
| 683 | |
| 684 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 685 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 686 property names to values. | |
| 687 | |
| 688 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 689 newly-created item and ``olddata`` is None. | |
| 690 | |
| 691 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 692 values of properties that were changed. | |
| 693 | |
| 694 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |
| 695 the retired or restored item and ``olddata`` is None. | |

2168 The form variable is a bit special because it's actually a python |
| 1142 | 2169 FieldStorage object. That means that you have two ways to access its |
| 2170 contents. For example, to look up the CGI form value for the variable | |
| 2171 "name", use the path expression:: | |
| 2172 | |
| 2173 request/form/name/value | |
| 2174 | |
| 2175 or the python expression:: | |

| 2722 -------------------------------------------- | |
| 2723 | |
| 2724 The web interface uses UTF-8 default. It may be overridden in both forms | |
| 2725 and a browser cookie. | |
| 2726 | |
| 2727 - In forms, use the ``@charset`` variable. | |
| 2728 - To use the cookie override, have the ``roundup_charset`` cookie set. | |
| 2729 | |
| 2730 In both cases, the value is a valid charset name (eg. ``utf-8`` or | |
| 2731 ``kio8-r``). | |
| 2732 | |
| 2733 Inside Roundup, all strings are stored and processed in utf-8. | |
