209 // patch by Sascha Carlin
211 // Revision 1.3 2004/02/17 12:11:36 rurban
212 // 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, ...)
214 // Revision 1.2 2004/01/26 09:18:00 rurban
215 // * changed stored pref representation as before.
216 // the array of objects is 1) bigger and 2)
217 // less portable. If we would import packed pref
218 // objects and the object definition was changed, PHP would fail.
219 // This doesn't happen with an simple array of non-default values.
220 // * use $prefs->retrieve and $prefs->store methods, where retrieve
221 // understands the interim format of array of objects also.
222 // * simplified $prefs->get() and fixed $prefs->set()
223 // * added $user->_userid and class '_WikiUser' portability functions
224 // * fixed $user object ->_level upgrading, mostly using sessions.
225 // this fixes yesterdays problems with loosing authorization level.
226 // * fixed WikiUserNew::checkPass to return the _level
227 // * fixed WikiUserNew::isSignedIn
228 // * added explodePageList to class PageList, support sortby arg
229 // * fixed UserPreferences for WikiUserNew
230 // * fixed WikiPlugin for empty defaults array
231 // * UnfoldSubpages: added pagename arg, renamed pages arg,
232 // removed sort arg, support sortby arg
234 // Revision 1.1 2003/11/04 18:41:41 carstenklapp
235 // New plugin which was submitted to the mailing list some time
236 // ago. (This is the best UpLoad function I have seen for PhpWiki so
237 // far. Cleaned up text formatting and typos from the version on the
238 // mailing list. Still needs a few adjustments.)
