Miscellaneous Threading
.......................

.. sidebar::

   **The GIL**

   * `GIL, over at the Python Wiki
     <https://wiki.python.org/moin/GlobalInterpreterLock>`__
   * `David Beazley: Understanding the Python GIL (Youtube)
     <https://youtu.be/Obt-vMVdM8s>`__

* Show how the load/modify/store conflict appears to not be an issue
  in Python (?) (:download:`code/race-load-modify-store.py`)

  * Could that be the `GIL <https://wiki.python.org/moin/GlobalInterpreterLock>`__
  * What's the GIL altogether?
  * Why could it be a bad idea to trust the GIL too much?
    (|longrightarrow| `PEP 703 <https://peps.python.org/pep-0703/>`__)
  * Jason Brownlee `mentions
    <https://superfastpython.com/thread-race-condition-shared-variable/>`__
    the same "issue" -- there is no race condition. There used to, he
    says, before Python 3.10, but nowadays there's not. He shows an
    contrived way to show a race (involving a ``time.sleep(0)``
    |:rolling_eyes:|)
  * Fix that with a mutex (show ``with`` usage!)

  * `Events <https://docs.python.org/3/library/threading.html#event-objects>`__. Maybe
    some live-hacked dice-rolling in a subthread.
  * :doc:`python:library/queue`

* Multiprocessing

  Simply walk through the introductory example in
  :doc:`python:library/multiprocessing`

Day 2: Clean Code (In A Broader Sense), Group Project Kickoff
-------------------------------------------------------------

Group Project: Discussion
.........................

* Data acquisition: gathering sensor data
* Varying kinds of sensors: physical hardware, internet proxy, MQTT, ...
* Varying kinds of information sinks: CSV, database, MQTT, ...
* Acquisition machinery: timestamping, frequency, buffering, ...

Clean Code?
...........

From :doc:`/trainings/material/soup/clean-code/group` ...

* :doc:`/trainings/material/soup/clean-code/craft-sw`
* :doc:`/about/site/work-in-progress/2022-04-13/seminar/clean-code-craftsmanship`

Design Patterns Overview
........................

* :doc:`/trainings/material/soup/cxx-design-patterns/uml/uml`
* :doc:`/trainings/material/soup/cxx-design-patterns/oo-principles`
* :doc:`Design patterns
  </trainings/material/soup/cxx-design-patterns/group>`: problems,
  possible solutions

Test Driven Development
.......................

* (Try to) establish mindset
* :doc:`/trainings/material/soup/python/swdev/pytest/intro`
* ``pytest`` fixtures

  * :doc:`pytest:how-to/tmp_path`
  * :doc:`pytest:how-to/monkeypatch`

Day 3: Group Project
--------------------

* Create two or three teams
* Use Test Driven Develpment (TDD) to formulate requirements
* *Loop: hack, fix, refactor*
