How to remove xmpp.process()
============================
Starting from slixmpp 1.8.0, running ``process()`` on an
XMLStream/ClientXMPP/ComponentXMPP instance is deprecated, and starting from
1.9.0, it will be removed.
Why
---
This has been the usual way of running an application using SleekXMPP/slixmpp
for ages, but it has come at a price: people do not understand how they
should run their application without it, or how to integrate their slixmpp
code with the rest of their asyncio application.
In essence, ``process()`` is only a very thin wrapper around asyncio loop
functions:
.. code-block:: python
if timeout is None:
if forever:
self.loop.run_forever()
else:
self.loop.run_until_complete(self.disconnected)
else:
tasks: List[Future] = [asyncio.sleep(timeout)]
if not forever:
tasks.append(self.disconnected)
self.loop.run_until_complete(asyncio.wait(tasks))
How
---
Hence it can be replaced according to what you want your application to do:
- To run forever, ``loop.run_forever()`` will work just fine
- To run until disconnected, ``loop.run_until_complete(xmpp.disconnected)``
will be enough (XMLStream.disconnected is an future which result is set when
the stream gets disconnected.
- To run for a scheduled time (and still abort when disconnected):
.. code-block:: python
tasks = [asyncio.sleep(timeout)]
tasks.append(xmpp.disconnected)
loop.run_until_complete(asyncio.wait(tasks))
There is no magic at play here and anything is possible if a more flexible
execution scheme is expected.
