Can one of the admins verify this patch?

annatisch

Added a couple of comments to the async clients - the same clients apply to the sync ones but I haven't duplicated them ;)

+            self._max_message_size_on_link = self._handler.message_handler._link.peer_max_message_size if\
+                self._handler.message_handler._link.peer_max_message_size\
+                else constants.MAX_MESSAGE_LENGTH_BYTES


Minor: This statement is a bit of mouthful - I think it would be cleaner just to do it with an "or" statement:

self._max_message_size = self._handler.message_handler._link.peer_max_message_size or constants.MAX_MESSAGE_LENGTH

Also I think it will need a pylint disable for protected-access.

good suggestion. Fixed

You fixed it in the sync class but not the async one :)

+            raise EventDataError('Max message size: {} is too large, acceptable max batch size is: {} bytes.'


I think this should just be a ValueError

changed to ValueError

+
+        return EventDataBatch(max_message_size if max_message_size else self._max_message_size_on_link, partition_key)


This can also be done with an "or" statement:
EventDataBatch(max_message_size or self._max_message_size....)

changed to use "or"

        # type:(Union[EventData, Union[List[EventData], Iterator[EventData], Generator[EventData]]], Union[str, bytes]) -> None


Type hint needs updating to include the EventDataBatch (assuming it can be passed in here)

Updated to
type:(Union[EventData, EventDataBatch, Iterable[EventData]], Union[str, bytes]) -> None

+            if isinstance(event_data, EventDataBatch):
+                wrapper_event_data = event_data


Does this mean that in the case of EventDataBatch we ignore the passed in partition key?

Yes, EventDataBatch wins. It also has partition_key.

In that case we should raise an error if a user tries to pass in the partition_key alongside a Batch object. Otherwise they might think the value they pass in being used when it's actually being ignored.

Can you please double check the uAMQP code for .gather()? I have a suspicion that it's not a repeatable operation.... though I could be wrong....

It works in our case

Where is this function used?

The try_add function is part of the API and supposed to be used by customers not by us.

Improperly routed to batch. Concerns batching of event hub events. @annatisch if you wanna review.

            yield ed

+    async def create_batch(self, max_size=None, partition_key=None):


I wonder if this function needs to be async.
I think it might be better to raise an error if this is called before the link is open, rather than have it open the connection.
Then the function doesn't need to be async and can simply return the Batch object.

As we're not exposing the producer.open api to user, if users want to use create_batch before they send, we need to open the connection for them internally to get the right peer link message size.

If we change the behaviour for the async create_batch (to raise an error if the connection isn't open) we will need to do the same thing here.

Same to the above async one. We should open internally first to get the right peer link message size.

Same comment as above regarding raising an error if partition_key is going to be ignored.

Code updated, an EventDataError will be raised if the keys don't match.

This can be a simple or-statement:
