58 The following is taken from the `Python Library Reference`__ (May 20, 2004) |
| 2910 | 59 section "ConfigParser -- Configuration file parser": |
| 60 | |
| 61 The configuration file consists of sections, led by a "[section]" header | |
| 62 and followed by "name = value" entries, with line continuations on a | |
| 63 newline with leading whitespace. Note that leading whitespace is removed | |
| 64 from values. The optional values can contain format strings which | |
| 65 refer to other values in the same section. Lines beginning with "#" or ";" | |
| 66 are ignored and may be used to provide comments. | |

| 178 be either absolute or relative to the directory containig this config file. | |
| 179 | |
| 180 filename -- default *blank* | |
| 181 Log file name for minimal logging facility built into Roundup. If no file | |
| 182 name specified, log messages are written on stderr. If above 'config' | |
| 183 option is set, this option has no effect. The path may be either absolute | |
| 184 or relative to the directory containig this config file. | |
| 185 | |

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

| 210 If your SMTP mail host provides or requires TLS (Transport Layer Security) | |
| 211 then you may set this option to 'yes'. | |
| 212 Allowed values: ``yes``, ``no`` | |
| 213 | |
| 214 tls_keyfile -- default *blank* | |
| 215 If TLS is used, you may set this option to the name of a PEM formatted | |
| 216 file that contains your private key. The path may be either absolute or | |
| 217 relative to the directory containig this config file. | |
| 218 | |
| 219 tls_certfile -- default *blank* | |
| 220 If TLS is used, you may set this option to the name of a PEM formatted | |
| 221 certificate chain file. The path may be either absolute or relative | |
| 222 to the directory containig this config file. | |
| 223 | |
| 224 charset -- utf-8 | |
| 225 Character set to encode email headers with. We use utf-8 by default, as | |
| 226 it's the most flexible. Some mail readers (eg. Eudora) can't cope with | |
| 227 that, so you might need to specify a more limited character set | |
| 228 (eg. iso-8859-1). | |
| 229 | |
| 230 debug -- default *blank* | |
| 231 Setting this option makes Roundup to write all outgoing email messages | |
| 232 to this file *instead* of sending them. This option has the same effect | |
| 233 as environment variable SENDMAILDEBUG. Environment variable takes | |
| 234 precedence. The path may be either absolute or relative to the directory | |
| 235 containig this config file. | |
| 236 | |

| 242 out "quoted" text from the message. Signatures are also stripped. | |
| 243 Allowed values: ``yes``, ``no`` | |
| 244 | |
| 245 leave_body_unchanged -- ``no`` | |
| 246 Preserve the email body as is - that is, keep the citations *and* | |
| 247 signatures. | |
| 248 Allowed values: ``yes``, ``no`` | |
| 249 | |
| 250 default_class -- ``issue`` | |
| 251 Default class to use in the mailgw if one isn't supplied in email subjects. | |
| 252 To disable, leave the value blank. | |
| 253 | |
| 254 Section **nosy** | |
| 255 Nosy messages sending | |
| 256 | |
| 257 messages_to_author -- ``no`` | |
| 258 Send nosy messages to the author of the message. | |
| 259 Allowed values: ``yes``, ``no``, ``new`` | |
| 260 | |
| 261 signature_position -- ``bottom`` | |
| 262 Where to place the email signature. | |
| 263 Allowed values: ``top``, ``bottom``, ``none`` | |
| 264 | |
| 265 add_author -- ``new`` | |
| 266 Does the author of a message get placed on the nosy list automatically? | |
| 267 If ``new`` is used, then the author will only be added when a message | |
| 268 creates a new issue. If ``yes``, then the author will be added on | |
| 269 followups too. If ``no``, they're never added to the nosy. | |
| 270 Allowed values: ``yes``, ``no``, ``new`` | |
| 271 | |
| 272 add_recipients -- ``new`` | |
| 273 Do the recipients (``To:``, ``Cc:``) of a message get placed on the nosy | |
| 274 list? If ``new`` is used, then the recipients will only be added when a | |
| 275 message creates a new issue. If ``yes``, then the recipients will be added | |
| 276 on followups too. If ``no``, they're never added to the nosy. | |
| 277 Allowed values: ``yes``, ``no``, ``new`` | |
| 278 | |
| 279 You may generate a new default config file using the ``roundup-admin | |
| 280 genconfig`` command. | |

353 Various parts of Roundup require these properties. Don't remove them. |
| 1832 | 354 |
| 355 **Change the type of a property** | |
| 356 Property types must *never* be changed - the database simply doesn't take | |
| 357 this kind of action into account. Note that you can't just remove a | |
| 358 property and re-add it as a new type either. If you wanted to make the | |
| 359 assignedto property a Multilink, you'd need to create a new property | |
| 360 assignedto_list and remove the old assignedto property. | |
| 361 | |
| 362 | |
| 363 What you can do to the schema | |
| 364 ----------------------------- | |
| 365 | |
| 366 Your schema may be changed at any time before or after the tracker has been | |
| 367 initialised (or used). You may: | |
| 368 | |
| 369 **Add new properties to classes, or add whole new classes** | |
| 370 This is painless and easy to do - there are generally no repurcussions | |
| 371 from adding new information to a tracker's schema. | |
| 372 | |
| 373 **Remove properties** | |
| 374 Removing properties is a little more tricky - you need to make sure that | |
| 375 the property is no longer used in the `web interface`_ *or* by the | |
| 376 detectors_. | |

| 582 Detector API | |
| 583 ------------ | |
| 584 | |
| 585 Auditors are called with the arguments:: | |
| 586 | |
| 587 audit(db, cl, itemid, newdata) | |
| 588 | |
| 589 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 590 IssueClass within the database, and ``newdata`` is a dictionary mapping | |
| 591 property names to values. | |
| 592 | |
| 593 For a ``create()`` operation, the ``itemid`` argument is None and | |
| 594 newdata contains all of the initial property values with which the item | |
| 595 is about to be created. | |
| 596 | |
| 597 For a ``set()`` operation, newdata contains only the names and values of | |
| 598 properties that are about to be changed. | |
| 599 | |
| 600 For a ``retire()`` or ``restore()`` operation, newdata is None. | |
| 601 | |
| 602 Reactors are called with the arguments:: | |
| 603 | |
| 604 react(db, cl, itemid, olddata) | |
| 605 | |
| 606 where ``db`` is the database, ``cl`` is an instance of Class or | |
| 607 IssueClass within the database, and ``olddata`` is a dictionary mapping | |
| 608 property names to values. | |
| 609 | |
| 610 For a ``create()`` operation, the ``itemid`` argument is the id of the | |
| 611 newly-created item and ``olddata`` is None. | |
| 612 | |
| 613 For a ``set()`` operation, ``olddata`` contains the names and previous | |
| 614 values of properties that were changed. | |
| 615 | |
| 616 For a ``retire()`` or ``restore()`` operation, ``itemid`` is the id of | |
| 617 the retired or restored item and ``olddata`` is None. | |

1887 The form variable is a bit special because it's actually a python |

| 1889 contents. For example, to look up the CGI form value for the variable | |
| 1890 "name", use the path expression:: | |
| 1891 | |
| 1892 request/form/name/value | |
| 1893 | |

| 2910 | 2417 8-bit character set support in Web interface |
| 2418 -------------------------------------------- | |
| 2419 | |
| 2420 The web interface uses UTF-8 default. It may be overridden in both forms | |
| 2421 and a browser cookie. | |
| 2422 | |
| 2423 - In forms, use the ``@charset`` variable. | |
| 2424 - To use the cookie override, have the ``roundup_charset`` cookie set. | |
| 2425 | |
| 2426 In both cases, the value is a valid charset name (eg. ``utf-8`` or | |
| 2427 ``kio8-r``). | |
| 2428 | |
| 2429 Inside Roundup, all strings are stored and processed in utf-8. | |
| 2430 Unfortunately, some older browsers do not work properly with | |
| 2431 utf8-encoded pages (e.g. Netscape Navigator 4 displays wrong | |
| 2432 characters in form fields). This version allows to change | |
| 2433 the character set for http transfers. To do so, you may add | |
| 2434 the following code to your ``page.html`` template:: | |
| 2435 | |
| 2436 <tal:block define="uri string:${request/base}${request/env/PATH_INFO}"> | |
| 2437 <a tal:attributes="href python:request.indexargs_href(uri, | |
| 2438 {'@charset':'utf-8'})">utf-8</a> | |
| 2439 <a tal:attributes="href python:request.indexargs_href(uri, | |
| 2440 {'@charset':'koi8-r'})">koi8-r</a> | |
| 2441 </tal:block> | |
| 2442 | |
| 2443 (substitute ``koi8-r`` with appropriate charset for your language). | |
| 2444 Charset preference is kept in the browser cookie ``roundup_charset``. | |
| 2445 | |
| 2446 Lines ``meta http-equiv`` added to the tracker templates in version 0.6.0 | |
| 2447 should be changed to include actual character set name:: | |
| 2448 | |
| 2449 <meta http-equiv="Content-Type" | |
| 2450 tal:attributes="content string:text/html;; charset=${request/client/charset}" | |
| 2451 /> | |
| 2452 | |
| 2453 The charset is also sent in the http header. | |
| 2454 | |
