|
|
|
+
|
|
|

|
|
+ sent using the `new task message protocol`_ to be introduced
|
|
|
+ in Celery 4.0 (
|
|
|
+
|
|
|
+ Users upgrading to Celery 4.0 when this is released are encouraged
|
|
|
+ to upgrade to this version as an intermediate step, as this
|
|
|
+ means workers not yet upgraded will be able to process
|
|
|
+ messages from clients/workers running 4.0.

|
|
|
+
|
|
|
+- ``Task.send_events`` can now be set to disable sending of events
|
|
|
+ for that task only.
|
|
|
+
|
|
|
+ Example when defining the task:
|
|
|
+
|
|
|
+ .. code-block:: python
|
|
|
+
|
|
|
+ @app.task(send_events=False)
|
|
|
+ def add(x, y):
|
|
|
+ return x + y
|
|
|
+
|
|
|
+- **Utils**: Fixed compatibility with recent :pypi:`psutil` versions
|
|
|
+ (Issue #3262).
|
|
|
+
|
|
|
+- **Canvas**: Chord now forwards partial arguments to its subtasks.
|
|
|
+
|
|
|
+ Fix contributed by Tayfun Sen.
|
|
|
+
|
|
|
+- **App**: Arguments to app such as ``backend``, ``broker``, etc
|
|
|
+ are now pickled and sent to the child processes on Windows.
|
|
|
+
|
|
|
+ Fix contributed by Jeremy Zafran.
|
|
|
+
|
|
|
+- **Deployment**: Generic init scripts now supports being symlinked
|
|
|
+ in runlevel directories (Issue #3208).
|
|
|
+
|
|
|
+- **Deployment**: Updated CentOS scripts to work with CentOS 7.

|
|
|
+
|
|
|
+- **Events**: The curses monitor no longer crashes when the
|
|
|
+ result of a task is empty.
|
|
|
+
|
|
|
+ Fix contributed by Dongweiming.
|
|
|
+
|
|
|
+- **Worker**: ``repr(worker)`` would crash when called early
|
|
|
+ in the startup process (Issue #2514).
|
|
|
+
|
|
|
+- **Tasks**: GroupResult now defines __bool__ and __nonzero__.
|
|
|
+
|
|
|
+ This is to fix an issue where a ResultSet or GroupResult with an empty
|
|
|
+ result list are not properly tupled with the as_tuple() method when it is
|
|
|
+ a parent result. This is due to the as_tuple() method performing a logical
|
|
|
+ and operation on the ResultSet.
|
|
|
+
|
|
|
+ Fix contributed by Colin McIntosh.
|
|
|
+
|
|
|
+- **Worker**: Fixed wrong values in autoscale related logging message.

|
