[python client] Why reject and release not available in new API ?
While trying to answer a question on the user list, I was trying to test the
behaviour around rejecting a message.
It seems the 'reject' and 'release' methods are missing from the session
class in the new API.
Is this a deliberate omission ? is there an alternate way of achieving the
same ?
(The C++ API does have these methods, all though the JMS API doesn't really
have anything of the sort).
Regards,
Rajith

That seems like an omission to me.

I raised https://issues.apache.org/jira/browse/QPID-3178 in order to
ensure we revisit this and aim for more consistency for the next release.

As Rajith says this is nice, but perhaps there should be some wrappers
for these as they are not intuitive for someone either coming from the C
++ API or the old API (IMO).

There aren't methods, but you can reject and release messages this way:
session.acknowledge(msg)
session.acknowledge(msg, Disposition(REJECTED))
session.acknowledge(msg, Disposition(RELEASED))
session.acknowledge(msg, Disposition(RELEASED, set_redelivered=True))
The pattern is supposed to allow a bit more flexibility since the set of
available dispositions is a bit more open ended than just reject and
release.
