Hello! While studying the QtContacts [1] and KCalExtended [2] APIs, I spent some time writing backends for them. Current state is that item import/export and change tracking work. QtContacts passes all Client::Source::qt_vcard30 tests except for testImport. That's because its set of supported properties is different from the Evolution test cases. For example, PHOTO does not seem to be stored at the moment. KCalExtended is still in rapid development right now. Just getting it to compile and link requires fiddling with the KCalExtended source. It fails some tests and is overall in a less stable state. Both backends are not meant to be used for actual syncing and are not supported - you have been warned ;-) But I'd like to merge the code into the "master" branch anyway. Yongsheng, can you do a normal code review of the "pohly" branch (contains the some unrelated fixes for master) and a quick check of the "qt" branch (based on "pohly", contains the new backends)?
