5.2.3

Fixed

Models - Errors

• Python 3.14 annotation NameError on DI wire - inspect.signature no
  longer raises NameError: LanguageType is not defined when
  dependency_injector inspects error constructors.
  • Python 3.14 PEP 649 defers annotation evaluation in __annotate__
  • TYPE_CHECKING-only names were missing from module globals at runtime
  • Added from __future__ import annotations so wiring sees string
    annotations and does not evaluate them

Adapters - Annotations

• Same 3.14 inspect.signature crash on adapter ports - SQLAlchemy,
  Elasticsearch, email, Kafka, Temporal, Redis mocks, Parsian, and Saman IPG
  callables with TYPE_CHECKING-only annotations now survive container.wire().

Helpers - Annotations

• Same 3.14 inspect.signature crash on helpers and decorators - Error, JWT,
  file, TOTP, Keycloak, datetime, and password utils, plus retry/timeout/cache/
  singleton/atomic/deprecation/timing decorators, gRPC interceptors, and
  FastAPIErrorResponseDTO no longer NameError during signature inspection.

Tests

Tests - Errors

• Constructor inspectability BDD - Public BaseError subclasses are
  asserted to resolve inspect.signature without NameError.
