61 The following is taken from the `Python Library Reference`__ (May 20, 2004) |
| 2910 | 62 section "ConfigParser -- Configuration file parser": |
| 63 | |
| 64 The configuration file consists of sections, led by a "[section]" header | |
| 65 and followed by "name = value" entries, with line continuations on a | |
| 66 newline with leading whitespace. Note that leading whitespace is removed | |
| 67 from values. The optional values can contain format strings which | |
| 68 refer to other values in the same section. Lines beginning with "#" or ";" | |
| 69 are ignored and may be used to provide comments. | |

| 181 be either absolute or relative to the directory containig this config file. | |
| 182 | |
| 183 filename -- default *blank* | |
| 184 Log file name for minimal logging facility built into Roundup. If no file | |
| 185 name specified, log messages are written on stderr. If above 'config' | |

| 206 If username is not empty, password (below) MUST be set! | |
| 207 | |
| 208 password -- default *blank* | |
| 209 SMTP login password. | |
| 210 Set this if your mail host requires authenticated access. | |

| 215 Allowed values: ``yes``, ``no`` | |
| 216 | |
| 217 tls_keyfile -- default *blank* | |
| 218 If TLS is used, you may set this option to the name of a PEM formatted | |
| 219 file that contains your private key. The path may be either absolute or | |
| 220 relative to the directory containig this config file. | |
| 221 | |
| 222 tls_certfile -- default *blank* | |
| 223 If TLS is used, you may set this option to the name of a PEM formatted | |
| 224 certificate chain file. The path may be either absolute or relative | |
| 225 to the directory containig this config file. | |
| 226 | |
| 227 charset -- utf-8 | |
| 228 Character set to encode email headers with. We use utf-8 by default, as | |
| 229 it's the most flexible. Some mail readers (eg. Eudora) can't cope with | |
| 230 that, so you might need to specify a more limited character set | |
| 231 (eg. iso-8859-1). | |
| 232 | |
| 233 debug -- default *blank* | |
| 234 Setting this option makes Roundup to write all outgoing email messages | |
| 235 to this file *instead* of sending them. This option has the same effect | |
| 236 as environment variable SENDMAILDEBUG. Environment variable takes | |
| 237 precedence. The path may be either absolute or relative to the directory | |
| 238 containig this config file. | |
| 239 | |

| 241 Roundup Mail Gateway options | |
| 242 | |
| 243 keep_quoted_text -- ``yes`` | |
| 244 Keep email citations when accepting messages. Setting this to ``no`` strips | |
| 245 out "quoted" text from the message. Signatures are also stripped. | |
| 246 Allowed values: ``yes``, ``no`` | |
| 247 | |
| 248 leave_body_unchanged -- ``no`` | |
| 249 Preserve the email body as is - that is, keep the citations *and* | |
| 250 signatures. | |
| 251 Allowed values: ``yes``, ``no`` | |
| 252 | |
| 253 default_class -- ``issue`` | |

357 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 358 |
| 359 **Change the type of a property** | |
| 360 Property types must *never* be changed - the database simply doesn't take | |
| 361 this kind of action into account. Note that you can't just remove a | |
| 362 property and re-add it as a new type either. If you wanted to make the | |
| 363 assignedto property a Multilink, you'd need to create a new property | |
| 364 assignedto_list and remove the old assignedto property. | |
| 365 | |
| 366 | |
| 367 What you can do to the schema | |
| 368 ----------------------------- | |
| 369 | |
| 370 Your schema may be changed at any time before or after the tracker has been | |
| 371 initialised (or used). You may: | |
| 372 | |
| 373 **Add new properties to classes, or add whole new classes** | |
| 374 This is painless and easy to do - there are generally no repurcussions | |
| 375 from adding new information to a tracker's schema. | |
| 376 | |
| 377 **Remove properties** | |
| 378 Removing properties is a little more tricky - you need to make sure that | |
| 379 the property is no longer used in the `web interface`_ *or* by the | |
| 380 detectors_. | |

| 606 property names to values. | |
| 607 | |
| 608 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 609 newdata contains all of the initial property values with which the item | |
| 610 is about to be created. | |
| 611 | |
| 612 For a ``set()`` operation, newdata contains only the names and values of | |
| 613 properties that are about to be changed. | |

| 615 For a ``retire()`` or ``restore()`` operation, newdata is None. | |

| 623 property names to values. | |
| 624 | |
| 625 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 626 newly-created item and ``olddata`` is None. | |
| 627 | |
| 628 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 629 values of properties that were changed. | |
| 630 | |
| 631 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |

2028 The form variable is a bit special because it's actually a python |
| 1142 | 2029 FieldStorage object. That means that you have two ways to access its |
| 2030 contents. For example, to look up the CGI form value for the variable | |
| 2031 "name", use the path expression:: | |
| 2032 | |
| 2033 request/form/name/value | |
| 2034 | |
| 2035 or the python expression:: | |
| 2036 | |

| 2577 -------------------------------------------- | |
| 2578 | |
| 2579 The web interface uses UTF-8 default. It may be overridden in both forms | |
| 2580 and a browser cookie. | |
| 2581 | |
| 2582 - In forms, use the ``@charset`` variable. | |
| 2583 - To use the cookie override, have the ``roundup_charset`` cookie set. | |
| 2584 | |
| 2585 In both cases, the value is a valid charset name (eg. ``utf-8`` or | |
| 2586 ``kio8-r``). | |
| 2587 | |
| 2588 Inside Roundup, all strings are stored and processed in utf-8. | |
