[xwiki-devs] Extension management - Questions

Dear all, some notes about my recent upgrade from 3.5 wiki farm to a 4.0 -- Sysem -- * Xwiki 4.0 farm (the old way, independent farm) * Jetty package that you provided xwiki-manaer-mysql-4.0 * 4 wikis (2 active, one template and the manager) * File attachments on filesystem -- Question -- 1) After I have upgraded from xem 3.5 to xem 4.0 all previously installed extensions have been removed from XEM control panel (but extension pages are still present) - minor bug, I have solved it reinstalling all extensions. 2) Since XEM 3.5 xwiki-manager can setup two different kind of multiple wikis: a) workspaces b) the old way wikifarm. - What is exactly the difference between that two? - XEM home page suggests to create workspaces and the old wikifarm is placed in a sub page, this create some confusion. I would prefer to have both options on the home page with some notes that explain differences. Personally I use the wiki farm (independent wikis). 3) In wikifarm (independent wikis) management of extensions is not clear. - If I install an extension from XEM it is installed in all sub-wikis, but if I remove it, it is removed only from XEM and not from sub-wikis (pages are still present but extension disappear form sub-wikis control panel, so it is impossible to completely remove them) - If I install an extension in sub-wiki, it is listed in XEM, but if I select it I see many errors. -- Bugs -- - One of the two wiki is constantly loosing web preferences settings (skins and localization template), no error in file log, really annoying and hard to debug. - Since webpreferences settings are lost, it is impossible to know what extensions were installed -- Workaround -- - Is it possible to have multiple wiki (completely independent) without using Xem? -- My proposal -- - If an extension is installed in XEM it can be removed only from XEM and this remove the extension form all sub-wikis (we could delete pages and send them in the recycler bin for better security) - If an extension is installed in sub-wikis it is only listed in the relative control panel of that wiki Thank you, Gianluca
