Entity.columns class property replaced by Entity.get_columns method. 
Again, Python < 3.9 doesn't like the combination of `@property` +
`@classmethod`.

_variable should be an external global function rather than a class property. 
The combination of `@property` + `@classmethod` isn't supported on
Python < 3.9.

Added timeout parameter to requests.get in the rss plugin. 2023-08-18 15:53:30 +02:00

Sync the latest parse timestamps in main instead of __init__ in rss. 
We should load the latest timestamps from the db when the thread starts
instead of doing it in the constructor.

The constructor may be invoked when the entities engine hasn't been
initialized yet, and result in deadlocks.

Added @ensure_initialized decorator to actions in variable. 
The `variable` plugin may break in the constructor the first time the
application is started.

That's because it tries to initialize the cache of stored variables, but
the local database hasn't yet been initialized.

That's because plugins are registered _before_ the entities engine is
initialized, as the entities engine assumes that it already has plugins
to scan for entities.

Therefore, the initialization of the `variable` plugin's cache should be
lazy (only done upon the first call to `get`/`set` etc.), in order to
prevent deadlock situations where the plugin waits for the engine to
start, but the engine will be initialized only after the plugin is
ready.

And the lazy initialization logic should also ensure that the entities
engine has been properly started (and emit a `TimeoutError` if that's
not the case), in order to prevent race conditions.

Extended manifest files with Python system packages (if available). 
- If a Python optional dependency is available as a system package on
  the target system, try and install it that route rather than pip. It's
  usually faster and it decreases the risk of breaking system packages.

- Added support for apk dependencies in manifest files. This brings the
  number of distros officially supported by all the extensions to four:

  - Alpine
  - Arch
  - Debian
  - Ubuntu

More improvements to the inspect plugin. 
- Support for distinct `type` field on constructor and method arguments.

- Added `has_varargs` field.

- Added `required` field.

- Better logic for parsing arguments `default` values.

Unified interface to retrieve the Redis bus configuration. 
A common `utils.get_redis_conf` has been created to handle the cascade
fallback logic used to retrive the default Redis configuration.

Catch TypeError when execution an action. 
Most of TypeError are due to the user passing wrong data. It usually
doesn't mean that we have to fail hard and reload the plugin, nor retry
the call with the same parameters.

Removed some optional top-level imports. 
Optional top-level imports in Tornado route declarations will trigger
`ImportError`. While this will just mean that those routes will be
skipped, it will also generate a lot of noise on the logs.

The inspect plugin should not fail hard if the cache couldn't be loaded. 
This can happen for many reasons - not only if the cache file is not
accessible, but also if the structure/signature of some pickled objects
has changed. In that case, we should invalidate the current cache and
re-initialize it instead of failing.

Refactored Tornado routes for native pub/sub support. 
The Redis pub/sub mechanism is now a native feature for Tornado routes
through the `PubSubMixin`.

(Plus, lint/black chore for the sound plugin)

Camera stream writer fixes. 
- The readiness condition should be `multiprocessing.Condition`, not
  `threading.Condition` - in most of the cases it will be checked in a
  multiprocess environment.

- Fixed parameter name for `write`.

Removed camera.gstreamer. 
Too much of a pain in the ass to handle, too many format options to
think of, too many combinations of pipelines to support, and if I don't
think of those beforehand then I'll have to offload all of that
complexity on the user.

Added multiple parsers for the entities referenced in docstrings. 
The `inspect` plugin can now detect references to plugins, backends,
events, responses and schemas in docstrings and replace them either with
links to the documentation or auto-generated examples.

Improved rendering of actions/arguments documentation. 
The frontend now calls `utils.rst_to_html` to render the docstrings as
HTML instead of dumping them as raw text.

Also, actions and arguments are now cached to improve performance.

Performance improvements when loading the Tensorflow plugin. 
The Tensorflow module may take a few seconds to load the first time and
slow down the first scan of the plugins.

All the Tensorflow imports should therefore be placed close to where
they are used instead of being defined at the top of the module.

Migrated the webapp to Tornado. 
It was just too painful to find a combination of versions of  gunicorn,
gevent, eventlet, pyuwsgi etc. that could work on all of my systems.

On the other hand, Tornado works out of the box with no headaches.

Also in this commit:

- Updated a bunch of outdated/required integration dependencies.
- Black'd and LINTed a couple of old plugins.
