Hi folks! Yesterday, we got a bug report about a crash at the moment to save the yast2-ftp-server configuration when "Allowing for anonymous upload" ... Caller: /usr/share/YaST2/modules/FtpServer.rb:522:in 'WriteUpload' Details: undefined method 'mkdir' for #Yast::FileUtilsClass:0x00001002ce2a2c0 ... After realizing that, probably, the code was written with the FileUtils Ruby module[1] in mind but the Yast::FileUtils module[2] is being called instead, two questions came two my mind - How much time has been this broken without nobody noticing/reporting it? The change was introduced exactly a year ago[3], do it means that the yast2-ftp-server is no longer relevant? - Do we have this problem in more places? I.e. Yast::FileUtils taking the place of Object::FileUtils. I don't have the answer for any of them ;) but I have a proposal[4] for the last one: to implement the `method_missing` in the Yast::FileUtils and fallback to Object::FileUtils. That way, we could avoid similar crashes. What do you think?
