Am I mistaken in thinking that we've periodically run into difficulties with this solution related to caching? ResolvePageName calls MakePageName which calls FmtPagename which calls PageVar which (a) calls PCache() (first problem) and (b) also calls PageTextVar which calls RetrieveAuthPage which normally calls PmWikiAuth (second problem). My recollection (I can search thru archives to confirm -- I may be remembering it wrong) is that the static $acache in PmWikiAuth as well as the general $PCache can both cause problems if they are called/cached early in config.php... Thus if I need $group or $name early on in my config.php I can either take a chance with $pagename without calling ResolvePageName or else take a chance that I will open the door to later difficulties with cached values (which are notoriously difficult to debug)... Now one "solution" is to say "just don't call ResolvePageName() until near the end of config.php". And this is generally possible... But there are certain circumstances (Oliver's appears to be a good example where he needs the values related to XL which needs to be early) when there needs to be a non-cache-dependent solution... PITS/01177 is related. -Peter _______________________________________________ pmwiki-users mailing list [email protected] http://www.pmichaud.com/mailman/listinfo/pmwiki-users
