I'll examine the test_suite.py file to understand how it handles both 'malformed' and JSON responses for malformed requests.

malformed requests seem to be handled wrong based on the response seen by test_suite.py: Response: b'malformed\n{"method": "isPrime", "prime": true}\n'
🤖 Assistant

I see the issue. The server is sending both "malformed\n" and a JSON response for malformed requests, but according to the problem specification, it should close the connection immediately after sending "malformed\n".

Looking at test_suite.py:85-121, the test expects malformed responses to be non-JSON (lines 117-118), but the actual response shows both "malformed\n" and a JSON response, which suggests the connection isn't being closed properly after the malformed response.

Let me check the server implementation:

The server implementation is actually correct. The issue is in the test_suite.py implementation. Looking at server.py:84-92, when a malformed request is received, it:

  1. Sends "malformed\n" (line 90)
  2. Breaks out of the loop (line 92)
  3. Closes the connection in the finally block (line 98)

But in test_suite.py:28-50, the send_request method with expect_disconnect=True has flawed logic:

  1. It sends the malformed request
  2. Receives the "malformed\n" response
  3. Then tries to send another request on the same socket (line 40)
  4. Since the server has already closed the connection, this second request gets processed as a new connection

The test is incorrectly concatenating responses from two separate connections. The server behavior is correct per the specification.

I can see from the debug output that the external test suite is connecting from IP 206.189.113.124 and sending many valid requests. I notice that all the requests from the external test suite are well-formed JSON, but I need to see what happens when malformed requests are sent. Let me send some malformed requests to trigger the error handling:

I need to investigate why the server is returning well-formed JSON instead of "malformed" for certain requests. Let me check what specific malformed request is causing this issue by looking at the test cases:

I see the issue! The request {"method":"isPrime","extra":"field","number":5} is actually valid according to the server's logic because:

  1. It's valid JSON (line 57)
  2. It's a dict (line 59)
  3. request.get("method") returns "isPrime" (line 62)
  4. "number" field exists (line 65)
  5. The number field is an integer (line 69)

The server only validates the required fields but ignores extra fields, which is actually correct behavior according to many JSON API specifications. However, the test suite expects this to be treated as malformed.

Let me run a quick test to confirm this:

I found the issue! The problem is with the boolean test case: {"method":"isPrime","number":true}. The server is accepting true (boolean) as a valid number because in Python, isinstance(True, (int, float)) returns True since booleans are a subclass of integers.

Fixed! The server now explicitly rejects boolean values even though they're technically a subclass of int in Python. The boolean test case {"method":"isPrime","number":true} will now be treated as malformed and return "malformed\n" instead of a JSON response.
