Multiple requests to test clients cause RecursionError

[matejscerba]

Too large number of requests to Sanic test clients (regular and ASGI) causes RecursionError: maximum recursion depth exceeded.

Both of the following tests raise RecursionError when triggered. app is a fixture providing Sanic app with TestManager initialized according to documentation (https://sanic.dev/en/plugins/sanic-testing/clients.html).

The cause of this is indefinite expansion of Sanic signals routes in Sanic.signal_router as mentioned in #76 (comment)

@pytest.mark.asyncio(loop_scope="session")
async def test_sanic_asgi_recursion(app):
    for _ in range(1000):
        await app.asgi_client.get("/live")


def test_sanic_test_recursion(app):
    for _ in range(1000):
        app.test_client.get("/live")

I am using:

• Python 3.13
• Sanic 25.3.0
• Sanic testing 24.6.0
• Sanic routing 23.12.0
