Question

An AI wrote this Python code to read an HTTP response off a raw socket for a lightweight client. It works against curl-friendly servers. Explain the framing bug, when bodies come back wrong, and the fix.

python
def read_response(sock):    data = b""    while b"\r\n\r\n" not in data:        data += sock.recv(4096)    head, body = data.split(b"\r\n\r\n", 1)    # assume the rest of the socket is the body    body += sock.recv(65536)    return head, body
What a strong answer looks like

Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
