[xwiki-devs] [Proposal] Virtual file system

Hi, I'd like to propose that in the future we implement a xwiki-filesystem module that has a virtual filesystem API. The idea is that all modules who need access to the file system go through this xwiki-filesystem module. We would implement it using Commons VFS (http://commons.apache.org/vfs/). This allows to use different filesystems: * For example in unit tests we would use a RAM filesystem. This allows not leaving files around during tests. * Users could configure XWiki to use a different filesystem (see http://commons.apache.org/vfs/filesystems.html) I have used commons vfs in the past on Cargo and it has worked great. I've just had a look at its releases and it's been a while since the last one. However activity seems to be picking up and provided we have our own interface I don't see a major issue. At worse we would only use RAM and file implementations. Disclaimer: I'm not planning to work on this anytime soon. Just wanted to share the idea with you so that we can decide if that's something we want or not. Thanks -Vincent
