175 // fix bogologin with passwd set.
176 // fix php crashes with call-time pass-by-reference (references wrongly used
177 // in declaration AND call). This affected mainly Apache2 and IIS.

208 // improved UserPreferences layout (tabled hints)
209 // fixed UserPreferences auth handling
210 // improved auth stability
211 // improved old cookie handling: fixed deletion of old cookies with paths
213 // Revision 1.22 2004/03/24 19:39:03 rurban
214 // php5 workaround code (plus some interim debugging code in XmlElement)
215 // php5 doesn't work yet with the current XmlElement class constructors,
216 // WikiUserNew does work better than php4.
217 // rewrote WikiUserNew user upgrading to ease php5 update
218 // fixed pref handling in WikiUserNew
219 // added Email Notification
220 // added simple Email verification
221 // removed emailVerify userpref subclass: just a email property
222 // changed pref binary storage layout: numarray => hash of non default values
223 // print optimize message only if really done.
224 // forced new cookie policy: delete pref cookies, use only WIKI_ID as plain string.
225 // prefs should be stored in db or homepage, besides the current session.
227 // Revision 1.21 2004/03/14 16:26:21 rurban
230 // Revision 1.20 2004/03/12 23:20:58 rurban
231 // pref fixes (base64)
233 // Revision 1.19 2004/02/27 13:21:17 rurban
234 // several performance improvements, esp. with peardb
236 // storepass seperated from prefs if defined so
237 // stacked and strict still not working
239 // Revision 1.18 2004/02/24 15:20:06 rurban
240 // fixed minor warnings: unchecked args, POST => Get urls for sortby e.g.
242 // Revision 1.17 2004/02/17 12:11:36 rurban
243 // 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, ...)
245 // Revision 1.16 2004/02/15 21:34:37 rurban
246 // PageList enhanced and improved.
247 // fixed new WikiAdmin... plugins
248 // editpage, Theme with exp. htmlarea framework
249 // (htmlarea yet committed, this is really questionable)
250 // WikiUser... code with better session handling for prefs
251 // enhanced UserPreferences (again)
252 // RecentChanges for show_deleted: how should pages be deleted then?
254 // Revision 1.15 2004/01/27 22:37:50 rurban
255 // fixed default args: no objects
257 // Revision 1.14 2004/01/26 09:18:00 rurban
258 // * changed stored pref representation as before.
259 // the array of objects is 1) bigger and 2)
260 // less portable. If we would import packed pref
261 // objects and the object definition was changed, PHP would fail.
262 // This doesn't happen with an simple array of non-default values.
263 // * use $prefs->retrieve and $prefs->store methods, where retrieve
264 // understands the interim format of array of objects also.
265 // * simplified $prefs->get() and fixed $prefs->set()
266 // * added $user->_userid and class '_WikiUser' portability functions
267 // * fixed $user object ->_level upgrading, mostly using sessions.
268 // this fixes yesterdays problems with loosing authorization level.
269 // * fixed WikiUserNew::checkPass to return the _level
270 // * fixed WikiUserNew::isSignedIn
271 // * added explodePageList to class PageList, support sortby arg
272 // * fixed UserPreferences for WikiUserNew
273 // * fixed WikiPlugin for empty defaults array
274 // * UnfoldSubpages: added pagename arg, renamed pages arg,
275 // removed sort arg, support sortby arg
277 // Revision 1.13 2003/12/04 20:27:00 carstenklapp
280 // Revision 1.12 2003/12/01 22:21:33 carstenklapp
281 // Bugfix: UserPreferences are no longer clobbered when signing in after
282 // the previous session has ended (i.e. user closed browser then signed
283 // in again). This is still a bit of a mess, and the preferences do not
284 // take effect until the next page browse/link has been clicked.
286 // Revision 1.11 2003/09/19 22:01:19 carstenklapp
287 // BOGO users allowed preferences too when ALLOW_BOGO_LOGIN == true.
289 // Revision 1.10 2003/09/13 21:57:26 carstenklapp
290 // Reformatting only.
292 // Revision 1.9 2003/09/13 21:53:41 carstenklapp
293 // Added lang and theme arguments, getVersion(), copyright and cvs log.
301 // c-hanging-comment-ender-p: nil
302 // indent-tabs-mode: nil
