Replace wrapper-based SessionMiddleware/OIDCApp with KayaMixin subclasses applied via KayaApp(mixins=[...]). Mixins hook into handle_request and handle_websocket via before/after hooks, so both ASGI and RSGI keep working. Mixin dependencies are applied automatically and deduplicated.

# kaya-session
|
|
|
|
Session management for the Kaya web framework.
|
|
|
|
Provides server-side, identity-agnostic HTTP sessions via a session cookie. The
|
|
session data is accessible from request handlers as `ctx.session`.
|
|
|
|
## Usage
|
|
|
|
```python
|
|
from kaya.core import KayaApp, HttpContext
|
|
from kaya.session import SessionMixin, InMemorySessionStore
|
|
|
|
session = SessionMixin(InMemorySessionStore())
|
|
app = KayaApp(mixins=[session])
|
|
|
|
@app.GET('/')
|
|
async def home(ctx: HttpContext):
|
|
n = ctx.session.get('visits', 0) + 1
|
|
ctx.session['visits'] = n
|
|
await ctx.send_str(200, f'visits: {n}')
|
|
```
|
|
|
|
Sessions are created lazily: a cookie is only set when the handler modifies the
|
|
session.
|
|
|
|
`SessionMixin` is a `KayaMixin`, so the app stays a `KayaApp` and both ASGI and
|
|
RSGI keep working.
|
|
|
|
## Session expiry
|
|
|
|
The cookie sent to the browser has a `Max-Age` (default 14 days), but that is
|
|
only a client-side hint. The real boundary is the store's server-side TTL,
|
|
which the mixin keeps in sync with the cookie `Max-Age`.
|
|
|
|
For `InMemorySessionStore`, a session expires if it is idle for longer than
|
|
`max_age`. Active sessions have their expiry slid forward on every access, so
|
|
a user that keeps visiting stays logged in. If the client ignores the cookie's
|
|
`Max-Age` and replays an old cookie value, the store rejects the expired
|
|
session and creates a fresh empty one.
|
|
|
|
Set `max_age=None` to disable server-side expiry (and the `Max-Age` cookie
|
|
attribute) entirely.
|
|
|
|
## Features
|
|
|
|
- `Session`: dict-like session object with modification tracking
|
|
- `SessionStore`: abstract store interface
|
|
- `InMemorySessionStore`: simple in-memory store for development/single-process
|
|
- `SessionMixin`: composable Kaya mixin managing session cookies and persistence
|
|
- Session ID regeneration (`session.regenerate_id()`) and invalidation
|
|
(`session.invalidate()`) for authentication layers
|
|
|
|
## Notes
|
|
|
|
- `InMemorySessionStore` does not survive process restarts and is not shared
|
|
across processes. Production deployments should use a store backed by a shared
|
|
storage system (planned).
