| 70 The configuration file consists of sections, led by a "[section]" header | |
| 71 and followed by "name = value" entries, with line continuations on a | |
| 72 newline with leading whitespace. Note that leading whitespace is removed | |

| 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 | |
| 186 name specified, log messages are written on stderr. If above 'config' | |

| 207 If username is not empty, password (below) MUST be set! | |
| 208 | |
| 209 password -- default *blank* | |
| 210 SMTP login password. | |
| 211 Set this if your mail host requires authenticated access. | |

| 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 | |
| 223 tls_certfile -- default *blank* | |
| 224 If TLS is used, you may set this option to the name of a PEM formatted | |
| 225 certificate chain file. The path may be either absolute or relative | |
| 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 | |
| 241 Section **mailgw** | |
| 242 Roundup Mail Gateway options | |
| 243 | |
| 244 keep_quoted_text -- ``yes`` | |
| 245 Keep email citations when accepting messages. Setting this to ``no`` strips | |
| 246 out "quoted" text from the message. Signatures are also stripped. | |
| 247 Allowed values: ``yes``, ``no`` | |
| 248 | |
| 249 leave_body_unchanged -- ``no`` | |
| 250 Preserve the email body as is - that is, keep the citations *and* | |
| 251 signatures. | |

363 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 364 |
| 365 **Change the type of a property** | |
| 366 Property types must *never* be changed - the database simply doesn't take | |
| 367 this kind of action into account. Note that you can't just remove a | |
| 368 property and re-add it as a new type either. If you wanted to make the | |
| 369 assignedto property a Multilink, you'd need to create a new property | |
| 370 assignedto_list and remove the old assignedto property. | |
| 371 | |
| 372 | |
| 373 What you can do to the schema | |
| 374 ----------------------------- | |
| 375 | |
| 376 Your schema may be changed at any time before or after the tracker has been | |
| 377 initialised (or used). You may: | |
| 378 | |
| 379 **Add new properties to classes, or add whole new classes** | |
| 380 This is painless and easy to do - there are generally no repurcussions | |
| 381 from adding new information to a tracker's schema. | |
| 382 | |
| 383 **Remove properties** | |
| 384 Removing properties is a little more tricky - you need to make sure that | |
| 385 the property is no longer used in the `web interface`_ *or* by the | |
| 386 detectors_. | |

| 609 | |
| 610 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 611 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 612 property names to values. | |
| 613 | |
| 614 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 615 newdata contains all of the initial property values with which the item | |
| 616 is about to be created. | |
| 617 | |
| 618 For a ``set()`` operation, newdata contains only the names and values of | |
| 619 properties that are about to be changed. | |
| 620 | |
| 621 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 622 | |
| 623 Reactors are called with the arguments:: | |
| 624 | |
| 625 react(db, cl, itemid, olddata) | |
| 626 | |
| 627 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 628 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 629 property names to values. | |
| 630 | |
| 631 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 632 newly-created item and ``olddata`` is None. | |
| 633 | |
| 634 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 635 values of properties that were changed. | |
| 636 | |
| 637 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |

2037 The form variable is a bit special because it's actually a python |
| 1142 | 2038 FieldStorage object. That means that you have two ways to access its |
| 2039 contents. For example, to look up the CGI form value for the variable | |
| 2040 "name", use the path expression:: | |
| 2041 | |
| 2042 request/form/name/value | |
| 2043 | |
| 2044 or the python expression:: | |

| 2590 The web interface uses UTF-8 default. It may be overridden in both forms | |

| 2594 - To use the cookie override, have the ``roundup_charset`` cookie set. | |
| 2595 | |
| 2596 In both cases, the value is a valid charset name (eg. ``utf-8`` or | |
| 2597 ``kio8-r``). | |
| 2598 | |
| 2599 Inside Roundup, all strings are stored and processed in utf-8. | |
