This allows to access distant instance, in a similar way as Pyro. - -* Publish/subscribe mechanism using ZMQ for communication among cubicweb - instances. The new zmq-address-sub and zmq-address-pub configuration variables - define where this communication occurs. As of this release this mechanism is - used for entity cache invalidation. - -* Improved WSGI support. While there is still some caveats, most of the code - which was twisted only is now generic and allows related functionalities to work - with a WSGI front-end. - -* Full undo/transaction support : undo of modification has eventually been - implemented, and the configuration simplified (basically you activate it or not - on an instance basis). - -* Controlling HTTP status code used is not much more easier : - - - `WebRequest` now has a `status_out` attribut to control the response status ; - - - most web-side exceptions take an optional ``status`` argument. - -API changes ------------ - -* The base registry implementation has been moved to a new - `logilab.common.registry` module (see #1916014). This includes code from : - - * `cubicweb.vreg` (the whole things that was in there) - * `cw.appobject` (base selectors and all). - - In the process, some renaming was done: - - * the top level registry is now `RegistryStore` (was `VRegistry`), but that - should not impact cubicweb client code ; - - * former selectors functions are now known as "predicate", though you still use - predicates to build an object'selector ; - - * for consistency, the `objectify_selector` decoraror has hence be renamed to - `objectify_predicate` ; - - * on the CubicWeb side, the `selectors` module has been renamed to - `predicates`. - - Debugging refactoring dropped the more need for the `lltrace` decorator. There - should be full backward compat with proper deprecation warnings. Notice the - `yes` predicate and `objectify_predicate` decorator, as well as the - `traced_selection` function should now be imported from the - `logilab.common.registry` module. - -* All login forms are now submitted to /login. Redirection to requested - page is now handled by the login controller (it was previously handle by the - session manager). - -* `Publisher.publish` has been renamed to `Publisher.handle_request`. This - method now contains generic version of logic previously handled by - Twisted. `Controller.publish` is **not** affected. - -Unintrusive API changes ------------------------ - -* New 'ldapfeed' source type, designed to replace 'ldapuser' source with - data-feed (i.e. copy based) source ideas. - -* New 'zmqrql' source type, similar to 'pyrorql' but using ømq instead of Pyro. - -* A new registry called `services` has appeared, where you can register - server-side `cubicweb.server.Service` child classes. Their `call` method can be - invoked from a web-side AppObject instance using new `self._cw.call_service` - method or a server-side one using `self.session.call_service`. This is a new - way to call server-side methods, much cleaner than monkey patching the - Repository class, which becomes a deprecated way to perform similar tasks. - -* a new `ajax-func` registry now hosts all remote functions (i.e. functions - callable through the `asyncRemoteExec` JS api). A convenience `ajaxfunc` - decorator will let you expose your python function easily without all the - appobject standard boilerplate. Backward compatibility is preserved. - -* the 'json' controller is now deprecated in favor of the 'ajax' one. - -* `WebRequest.build_url` can now take a __secure__ argument. When True cubicweb - try to generate an https url. - - -User interface changes ----------------------- - -A new 'undohistory' view expose the undoable transactions and give access to undo -some of them.
