The eventlet API has way too many dependency issues with gunicorn.
Still TODO: Fix or at least mitigate the WSGI workers timeout issue when
they handle websocket connections.
Reason: gunicorn maintainers no longer give a fuck about their project
and they aren't letting anybody take over either - see
https://github.com/benoitc/gunicorn/pull/2581
This is not how a FOSS project should be run. A project with 9k stars
and countless usages shouldn't end up in a situation where users beg for
two years for a new release that fixes a bad regression and a bad
security vulnerability. The way gunicorn is maintained and run is an
insult to the whole FOSS community.
The websocket service is no longer provided by a different service,
controlled by a different thread running on another port.
Instead, it's now exposed directly over Flask routes, using
WSGI+eventlet+simple_websocket.
Also, the SSL context options have been removed from `backend.http`, for
sake of simplicity. If you want to enable SSL, you can serve Platypush
through a reverse proxy like nginx.
Added `waitress` dependency. For performance and security reasons, it's
better to always run the Flask application inside of a uWSGI server.
`waitress` also makes things easier by avoiding to ask the user to
manually provide the external executable arguments, as it was the case
with `uwsgi` and `gunicorn`.
Added Alembic environment and `run_db_migrations` logic to the entities
engine so database schema changes can be processed as soon as the
application is started.
- Merged together Bluetooth legacy and BLE plugins and scanners.
- Introduced Theengs as a dependency to infer BLE device types and
create sub-entities appropriately.
- Using `BluetoothDevice` and `BluetoothService` entities as the bread
and butter for all the Bluetooth plugin's components.
- Using a shared cache of devices and services between the legacy and
BLE integrations, with merging/coalescing logic included.
- Extended list of discoverable services to include all those officially
supported by the Bluetooth specs.
- Instantiate a separate pool of workers to discover services.
- Refactor of the Bluetooth events - all of them are now instantiated
from a single `BluetoothDevice` object.
SQLAlchemy 2 has introduced several breaking changes that can break
several things in the application - especially where the code uses
`connection.execute()` with raw SQL statements.
We need to temporarily force the installation of versions from the 1.x
branch, while migrating the existing code to the new version.
- Out `gattlib` + `pybluez`, in `bleak`. It's not platform-dependent, it doesn't
require libboost and other heavy build dependencies, and it doesn't require the
user that runs the service from having special privileges to access raw
Bluetooth sockets.
- Better integration with Platypush native entities. The devices are now mapped
to write-only `EnumSwitch` entities, and the status returns the serialized
representation of those entities instead of the previous intermediate
representation.
PyJWT is a very brittle and cumbersome dependency that expects several
cryptography libraries to be already installed on the system, and it can
lead to hard-to-debug errors when ported to different systems.
Moreover, it installs the whole `cryptography` package, which is several
MBs in size, takes time to compile, and it requires a Rust compiler to
be present on the target machine.
Platypush will now use the Python-native `rsa` module to handle JWT
tokens.
If Platypush is supposed to work also without a manually created
`config.yaml`, and the HTTP backend is enabled by default in that
configuration, then Flask and companions should be among the required
dependencies.
- Added ability to listen for signals
- Improved introspection output
- `dbus` plugin and backend have now been merged
- Migrated from `dbus` to `pydbus`
gunicorn makes it easier to set up a uWSGI wrapper
around the web application, and it's easier to
install and document than handling uwsgi as an
external system dependency.
