171 // fix encrypted usage, actually store and retrieve them from db
172 // fix bogologin with passwd set.
173 // fix php crashes with call-time pass-by-reference (references wrongly used
174 // in declaration AND call). This affected mainly Apache2 and IIS.
175 // (Thanks to John Cole to detect this!)
177 // Revision 1.29 2004/05/06 13:26:01 rurban

205 // improved UserPreferences layout (tabled hints)
206 // fixed UserPreferences auth handling
207 // improved auth stability
208 // improved old cookie handling: fixed deletion of old cookies with paths
210 // Revision 1.22 2004/03/24 19:39:03 rurban
211 // php5 workaround code (plus some interim debugging code in XmlElement)
212 // php5 doesn't work yet with the current XmlElement class constructors,
213 // WikiUserNew does work better than php4.
214 // rewrote WikiUserNew user upgrading to ease php5 update
215 // fixed pref handling in WikiUserNew
216 // added Email Notification
217 // added simple Email verification
218 // removed emailVerify userpref subclass: just a email property

220 // print optimize message only if really done.
221 // forced new cookie policy: delete pref cookies, use only WIKI_ID as plain string.
222 // prefs should be stored in db or homepage, besides the current session.
224 // Revision 1.21 2004/03/14 16:26:21 rurban
227 // Revision 1.20 2004/03/12 23:20:58 rurban
228 // pref fixes (base64)
230 // Revision 1.19 2004/02/27 13:21:17 rurban
231 // several performance improvements, esp. with peardb
233 // storepass seperated from prefs if defined so
234 // stacked and strict still not working
236 // Revision 1.18 2004/02/24 15:20:06 rurban
237 // fixed minor warnings: unchecked args, POST => Get urls for sortby e.g.
239 // Revision 1.17 2004/02/17 12:11:36 rurban
240 // added missing 4th basepage arg at plugin->run() to almost all plugins. This caused no harm so far, because it was silently dropped on normal usage. However on plugin internal ->run invocations it failed. (InterWikiSearch, IncludeSiteMap, ...)
242 // Revision 1.16 2004/02/15 21:34:37 rurban
243 // PageList enhanced and improved.
244 // fixed new WikiAdmin... plugins
245 // editpage, Theme with exp. htmlarea framework
246 // (htmlarea yet committed, this is really questionable)
247 // WikiUser... code with better session handling for prefs
248 // enhanced UserPreferences (again)
249 // RecentChanges for show_deleted: how should pages be deleted then?
251 // Revision 1.15 2004/01/27 22:37:50 rurban
252 // fixed default args: no objects
254 // Revision 1.14 2004/01/26 09:18:00 rurban
255 // * changed stored pref representation as before.
256 // the array of objects is 1) bigger and 2)
257 // less portable. If we would import packed pref
258 // objects and the object definition was changed, PHP would fail.
259 // This doesn't happen with an simple array of non-default values.
260 // * use $prefs->retrieve and $prefs->store methods, where retrieve
261 // understands the interim format of array of objects also.
262 // * simplified $prefs->get() and fixed $prefs->set()
263 // * added $user->_userid and class '_WikiUser' portability functions
264 // * fixed $user object ->_level upgrading, mostly using sessions.
265 // this fixes yesterdays problems with loosing authorization level.
266 // * fixed WikiUserNew::checkPass to return the _level
267 // * fixed WikiUserNew::isSignedIn
268 // * added explodePageList to class PageList, support sortby arg
269 // * fixed UserPreferences for WikiUserNew
270 // * fixed WikiPlugin for empty defaults array
271 // * UnfoldSubpages: added pagename arg, renamed pages arg,
272 // removed sort arg, support sortby arg
274 // Revision 1.13 2003/12/04 20:27:00 carstenklapp
277 // Revision 1.12 2003/12/01 22:21:33 carstenklapp
278 // Bugfix: UserPreferences are no longer clobbered when signing in after
279 // the previous session has ended (i.e. user closed browser then signed
280 // in again). This is still a bit of a mess, and the preferences do not
281 // take effect until the next page browse/link has been clicked.
283 // Revision 1.11 2003/09/19 22:01:19 carstenklapp
284 // BOGO users allowed preferences too when ALLOW_BOGO_LOGIN == true.
286 // Revision 1.10 2003/09/13 21:57:26 carstenklapp
287 // Reformatting only.
289 // Revision 1.9 2003/09/13 21:53:41 carstenklapp
290 // Added lang and theme arguments, getVersion(), copyright and cvs log.
298 // c-hanging-comment-ender-p: nil
299 // indent-tabs-mode: nil
