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

| 144 | |
| 145 web -- ``http://host.example/demo/`` | |
| 146 The web address that the tracker is viewable at. | |

| 149 that is required to get to the home page of the tracker. | |

| 180 be either absolute or relative to the directory containig this config file. | |
| 181 | |
| 182 filename -- default *blank* | |
| 183 Log file name for minimal logging facility built into Roundup. If no file | |
| 184 name specified, log messages are written on stderr. If above 'config' | |
| 185 option is set, this option has no effect. The path may be either absolute | |
| 186 or relative to the directory containig this config file. | |
| 187 | |

| 203 username -- default *blank* | |
| 204 SMTP login name. Set this if your mail host requires authenticated access. | |
| 205 If username is not empty, password (below) MUST be set! | |
| 206 | |
| 207 password -- default *blank* | |
| 208 SMTP login password. | |
| 209 Set this if your mail host requires authenticated access. | |

| 214 Allowed values: ``yes``, ``no`` | |
| 215 | |
| 216 tls_keyfile -- default *blank* | |
| 217 If TLS is used, you may set this option to the name of a PEM formatted | |
| 218 file that contains your private key. The path may be either absolute or | |
| 219 relative to the directory containig this config file. | |
| 220 | |

| 222 If TLS is used, you may set this option to the name of a PEM formatted | |
| 223 certificate chain file. The path may be either absolute or relative | |
| 224 to the directory containig this config file. | |
| 225 | |
| 226 charset -- utf-8 | |
| 227 Character set to encode email headers with. We use utf-8 by default, as | |
| 228 it's the most flexible. Some mail readers (eg. Eudora) can't cope with | |
| 229 that, so you might need to specify a more limited character set | |
| 230 (eg. iso-8859-1). | |
| 231 | |
| 232 debug -- default *blank* | |
| 233 Setting this option makes Roundup to write all outgoing email messages | |
| 234 to this file *instead* of sending them. This option has the same effect | |
| 235 as environment variable SENDMAILDEBUG. Environment variable takes | |
| 236 precedence. The path may be either absolute or relative to the directory | |
| 237 containig this config file. | |
| 238 | |

| 240 Roundup Mail Gateway options | |
| 241 | |
| 242 keep_quoted_text -- ``yes`` | |
| 243 Keep email citations when accepting messages. Setting this to ``no`` strips | |
| 244 out "quoted" text from the message. Signatures are also stripped. | |
| 245 Allowed values: ``yes``, ``no`` | |
| 246 | |
| 247 leave_body_unchanged -- ``no`` | |
| 248 Preserve the email body as is - that is, keep the citations *and* | |
| 249 signatures. | |
| 250 Allowed values: ``yes``, ``no`` | |
| 251 | |
| 252 default_class -- ``issue`` | |
| 253 Default class to use in the mailgw if one isn't supplied in email subjects. | |
| 254 To disable, leave the value blank. | |
| 255 | |
| 256 Section **nosy** | |
| 257 Nosy messages sending | |

355 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 356 |
| 357 **Change the type of a property** | |
| 358 Property types must *never* be changed - the database simply doesn't take | |
| 359 this kind of action into account. Note that you can't just remove a | |
| 360 property and re-add it as a new type either. If you wanted to make the | |
| 361 assignedto property a Multilink, you'd need to create a new property | |
| 362 assignedto_list and remove the old assignedto property. | |
| 363 | |
| 364 | |
| 365 What you can do to the schema | |
| 366 ----------------------------- | |
| 367 | |
| 368 Your schema may be changed at any time before or after the tracker has been | |
| 369 initialised (or used). You may: | |
| 370 | |
| 371 **Add new properties to classes, or add whole new classes** | |
| 372 This is painless and easy to do - there are generally no repurcussions | |
| 373 from adding new information to a tracker's schema. | |
| 374 | |
| 375 **Remove properties** | |
| 376 Removing properties is a little more tricky - you need to make sure that | |
| 377 the property is no longer used in the `web interface`_ *or* by the | |
| 378 detectors_. | |

| 585 ------------ | |
| 586 | |
| 587 Auditors are called with the arguments:: | |
| 588 | |
| 589 audit(db, cl, itemid, newdata) | |
| 590 | |
| 591 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 592 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 593 property names to values. | |
| 594 | |
| 595 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 596 newdata contains all of the initial property values with which the item | |
| 597 is about to be created. | |
| 598 | |
| 599 For a ``set()`` operation, newdata contains only the names and values of | |
| 600 properties that are about to be changed. | |
| 601 | |
| 602 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 603 | |
| 604 Reactors are called with the arguments:: | |
| 605 | |
| 606 react(db, cl, itemid, olddata) | |
| 607 | |
| 608 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 609 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 610 property names to values. | |
| 611 | |
| 612 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 613 newly-created item and ``olddata`` is None. | |
| 614 | |
| 615 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 616 values of properties that were changed. | |
| 617 | |
| 618 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |
| 619 the retired or restored item and ``olddata`` is None. | |

| 1982 request/form/name/value | |
| 1983 | |

| 2910 | 2524 8-bit character set support in Web interface |
| 2525 -------------------------------------------- | |
| 2526 | |
| 2527 The web interface uses UTF-8 default. It may be overridden in both forms | |
| 2528 and a browser cookie. | |
| 2529 | |
| 2530 - In forms, use the ``@charset`` variable. | |
| 2531 - To use the cookie override, have the ``roundup_charset`` cookie set. | |
| 2532 | |
| 2533 In both cases, the value is a valid charset name (eg. ``utf-8`` or | |
| 2534 ``kio8-r``). | |
| 2535 | |
| 2536 Inside Roundup, all strings are stored and processed in utf-8. | |
| 2537 Unfortunately, some older browsers do not work properly with | |
| 2538 utf8-encoded pages (e.g. Netscape Navigator 4 displays wrong | |
| 2539 characters in form fields). This version allows to change | |
| 2540 the character set for http transfers. To do so, you may add | |
| 2541 the following code to your ``page.html`` template:: | |
| 2542 | |
| 2543 <tal:block define="uri string:${request/base}${request/env/PATH_INFO}"> | |
| 2544 <a tal:attributes="href python:request.indexargs_href(uri, | |
| 2545 {'@charset':'utf-8'})">utf-8</a> | |
| 2546 <a tal:attributes="href python:request.indexargs_href(uri, | |
| 2547 {'@charset':'koi8-r'})">koi8-r</a> | |
| 2548 </tal:block> | |
| 2549 | |
| 2550 (substitute ``koi8-r`` with appropriate charset for your language). | |
| 2551 Charset preference is kept in the browser cookie ``roundup_charset``. | |
| 2552 | |
| 2553 Lines ``meta http-equiv`` added to the tracker templates in version 0.6.0 | |
| 2554 should be changed to include actual character set name:: | |
| 2555 | |
| 2556 <meta http-equiv="Content-Type" | |
| 2557 tal:attributes="content string:text/html;; charset=${request/client/charset}" | |
| 2558 /> | |
| 2559 | |
| 2560 The charset is also sent in the http header. | |
| 2561 | |
| 2562 | |
