242 // characters. Patch #1037825
244 // Revision 1.15 2004/09/22 13:46:26 rurban
245 // centralize upload paths.
246 // major WikiPluginCached feature enhancement:

248 // mainly for debugging, cache problems and action=pdf
250 // Revision 1.14 2004/06/16 10:38:59 rurban
251 // Disallow refernces in calls if the declaration is a reference
252 // ("allow_call_time_pass_reference clean").
253 // PhpWiki is now allow_call_time_pass_reference = Off clean,
254 // but several external libraries may not.
255 // In detail these libs look to be affected (not tested):
259 // Revision 1.13 2004/06/14 11:31:39 rurban
260 // renamed global $Theme to $WikiTheme (gforge nameclash)
261 // inherit PageList default options from PageList
262 // default sortby=pagename
263 // use options in PageList_Selectable (limit, sortby, ...)
264 // added action revert, with button at action=diff
265 // added option regex to WikiAdminSearchReplace
267 // Revision 1.12 2004/06/13 11:34:22 rurban
268 // fixed bug #969532 (space in uploaded filenames)
269 // improved upload error messages
271 // Revision 1.11 2004/06/11 09:07:30 rurban

274 // Revision 1.10 2004/04/12 10:19:18 rurban
275 // fixed copyright year
277 // Revision 1.9 2004/04/12 10:18:22 rurban
278 // removed the hairy regex line
280 // Revision 1.8 2004/04/12 09:12:22 rurban
283 // Revision 1.7 2004/04/09 17:49:03 rurban
284 // Added PhpWiki RssFeed to Sidebar
285 // sidebar formatting
286 // some browser dependant fixes (old-browser support)
288 // Revision 1.6 2004/02/27 01:36:51 rurban
291 // Revision 1.5 2004/02/27 01:24:43 rurban
292 // use IntwerWiki links for uploaded file.
293 // autolink to page prepared, but not yet ready
295 // Revision 1.4 2004/02/21 19:12:59 rurban
296 // patch by Sascha Carlin
298 // Revision 1.3 2004/02/17 12:11:36 rurban
299 // 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, ...)
301 // Revision 1.2 2004/01/26 09:18:00 rurban
302 // * changed stored pref representation as before.
303 // the array of objects is 1) bigger and 2)
304 // less portable. If we would import packed pref
305 // objects and the object definition was changed, PHP would fail.
306 // This doesn't happen with an simple array of non-default values.
307 // * use $prefs->retrieve and $prefs->store methods, where retrieve
308 // understands the interim format of array of objects also.
309 // * simplified $prefs->get() and fixed $prefs->set()
310 // * added $user->_userid and class '_WikiUser' portability functions
311 // * fixed $user object ->_level upgrading, mostly using sessions.
312 // this fixes yesterdays problems with loosing authorization level.
313 // * fixed WikiUserNew::checkPass to return the _level
314 // * fixed WikiUserNew::isSignedIn
315 // * added explodePageList to class PageList, support sortby arg
316 // * fixed UserPreferences for WikiUserNew
317 // * fixed WikiPlugin for empty defaults array
318 // * UnfoldSubpages: added pagename arg, renamed pages arg,
319 // removed sort arg, support sortby arg
321 // Revision 1.1 2003/11/04 18:41:41 carstenklapp
322 // New plugin which was submitted to the mailing list some time
323 // ago. (This is the best UpLoad function I have seen for PhpWiki so
324 // far. Cleaned up text formatting and typos from the version on the
325 // mailing list. Still needs a few adjustments.)
