Version 0.7.0 (2024-09-17)

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.

Deleted

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