2.2.0

modern-di-aiohttp 2.2.0 — adopt the modern-di integration kit

Maintenance release. No public API change — FromDI, inject,
setup_di, fetch_di_container, fetch_request_container, and the
connection providers keep their signatures and behavior. Swaps this
package's hand-rolled connection dispatch and marker resolution for the
shared primitives in
modern_di.integrations,
shipped in
modern-di 2.28.0.
Fourth of 13 planned adapter conversions across the modern-di ecosystem
(after
modern-di-starlette 2.2.0,
modern-di-fastapi 2.10.0,
and
modern-di-litestar 2.13.0).

Internal refactors

• _di_middleware keeps its own can_prepare() handshake probe to
  select aiohttp_websocket_provider or aiohttp_request_provider — this
  package is a documented outlier: both providers bind web.Request (a
  WebSocket is an upgraded HTTP request at aiohttp's middleware entry
  point), so integrations.classify_connection's isinstance-over-tuple
  dispatch cannot distinguish them. Once the provider is picked,
  integrations.bind(provider, request) now derives the scope/context
  the middleware used to hand-write. bind() never returns None, so no
  fallback branch is needed.
• The child container's manual try/finally: await child_container.close_async() is now Container's own async with —
  entering an already-open container is a no-op; exiting closes it,
  including on the exception path.
• _FromDI/_parse_inject_params/_resolve_di_params are gone.
  FromDI = integrations.from_di; inject now composes
  integrations.parse_markers/integrations.resolve_markers.

Packaging

• Bumps the modern-di floor to >=2.28.0,<3.

Downstream

No action needed — the public API (FromDI, inject, setup_di,
fetch_di_container, fetch_request_container,
aiohttp_request_provider/aiohttp_websocket_provider) is unchanged.
Upgrading only requires modern-di>=2.28.0.

Internals

• 100% line coverage; ruff, ty clean across Python 3.10–3.14.
• Built via subagent-driven-development: 5 planned tasks, each with an
  independent spec+quality review; a whole-branch review before merge.
