Convert `MetadataHandler` to an abstract base class and add an
`is_enabled` class method that allows every metadata handler to
independently report whether it is enabled based on its configuration.
This avoids the need for global variables in the config module, allowing
us to change the enabled state of a metadata handler at runtime if
needed.
Add a new scheduled task that syncs RetroAchievements progress for all
users with a RetroAchievements username.
Environment variables:
- `ENABLE_SCHEDULED_RETROACHIEVEMENTS_PROGRESS_SYNC`: Enable or disable
the task (default: `false`)
- `SCHEDULED_RETROACHIEVEMENTS_PROGRESS_SYNC_CRON`: Cron string to
schedule the task (default: "0 4 * * *" - daily at 4 AM)
This change adds a new environment variable `DB_QUERY_JSON` that allows
users to specify querystring values for additional database connection
parameters. This is useful for passing custom query parameters to the
database connection URL.
The `DB_QUERY_JSON` variable should contain a JSON string with key-value
pairs of strings, which is the required format for the SQLAlchemy URL
`query` parameter. If the variable is not set, no additional query
parameters will be added to the database connection URL.
Closes#2093.
For client_id/client_secret combinations, and API keys, we are certain
that they should not have leading/trailing whitespaces. We can strip
them to avoid any potential issues for users who might have added them
incorrectly in their Docker Compose configuration.
This change does NOT affect users/passwords, where leading/trailing
whitespaces might be intentional and valid.
The `WEB_CONCURRENCY` environment variable is a more common way to
configure the number of workers for Gunicorn [1] or other web servers.
This change maintains `GUNICORN_WORKERS` compatibility, while notifying
users that it is deprecated and should be replaced with
`WEB_CONCURRENCY`.
It would also allow us to replace Gunicorn with another web server in
the future without changing the variable name.
