[xwiki-devs] [Idea] xwiki-sanity module/application

Hi devs, I'd like to explore the idea of having a xwiki-sanity module which would be in charge of making verifications in a running XE/XEM instance and reporting issues/making fixes were needed. We could also have a counterpart xwiki-sanity application (XAR). Here are some potential use cases (I'm sure we can find lots of others): * Check DB version and perform migrations of the schema accordingly (our current migration system which is currently located in xwiki-core) * Perform various checks on DB settings, cache settings, etc * Perform deprecation call checks in velocity (the current deprecated uberspector) * More specific checks. For example: intercept the call to the velocity macro and add a check on: if the page where the velocity is executed is called Blog.BlogSheet and the content of the velocity contains "#getEntryDate($entryDoc $entryObj $entryDate)" and the platform version is >= 3.0M1 then don't execute the macro but instead display the message "The Blog application is not compatible with this version of XE, please upgrade to the latest Blog application". WDYT? Thanks -Vincent
