Version 0.7

[hartym]

Added

• Core: Stream attribute in both HttpRequest and HttpResponse to allow handling streaming objects and to get closer to
  httpx interfaces.
• Core/Http: Stream attribute in both HttpRequest and HttpResponse to allow handling streaming objects and to get
  closer to httpx interfaces.
• Core/Services: Services definitions are now using a declarative configuration format, that can be loaded by
  applications. A sphinx extension was added to automatically document service definitions from applications.
• Core/Services: Ability to include another services.yml file, either by absolute path (using
  "!include /path/to/other.yml") or from a python package path, using "!include services.yml from my.package" syntax.
• Notifications: Implements a simple way to send notifications to a slack or a google chat webhook to catch errors.
• Proxy: Added support for multiple remote urls for a given endpoint.
• Proxy: Added support for default/fallback pools in remote configuration for resilience.
• Proxy: Added a simple but functional circuit breaker implementation.
• Proxy: Add probe implementation in background.
• Proxy: Add liveness configuration support to proxy (in both remote endpoints and remote) to be able to select a
  liveness check algorithm. For now, supported algorithms are "ignore" (do nothing), "naive" (old behaviour with simple
  thresholds), "leaky" for a leaking bucket, and "inherit" (use parent algorithm). The default is "inherit", and if all
  settings in config chain are set to "inherit", the top-level default is "naive".
• Frontend: Generate typescript types from models, using the intermediary json schema generation provided by pydantic.
• Storage: Added a new db:merge command to generate merge revisions from alembic.

Changed

• Config: the settings are now implemented using pydantic, with more strictness so that settings only contains settings
  and state-related things are moved to wrappers. The new harp.config.Configurable base class is now used for all
  settings classes, and a new harp.config.Stateful allows to define settings wrappers for stateful objects.
• Config: Redis configuration is now separated from blob storage, as it may be used by much more than just blobs.
• Core: EVENT_CONTROLLER_VIEW event has been renamed to EVENT_CORE_VIEW for consistency with other event names.
• Core/Http: Removed WrappedHttpRequest, inner HttpRequests can now be accessed directly.
• Core/Http: HttpRequest can now be instanciated without an explicit implementation. If no implementation is provided,
  then the kwargs data is passed to a stub implementation, allowing a simpler way to create requests (in tests, for
  example).
• DX: adds a harp examples list command to list available examples
• DX/Helm: adds the ability to override environment in helm chart's values

Fixed

• Storage: added missing index on messages.transaction_id to speed up dashboard search queries.
• Erroneous frontend compiled assets path change reverted so that docker builds are not broken.

Deleted

• Config: old settings classes have been removed (Definition, DisableableBaseSettings, DisabledSettings, Lazy, Settings)
  along with related helper (settings_dataclass).

Notes

The 0.7.0 release has been deleted shortly after being released, as a docker image configruration issue was found during the initial tests, causing the image to not start. The 0.7.1 version is the real first 0.7 version.
