[Ask] Trying to parse a response and the proxy just stops

[alexandresgf]

Hello,

I'm trying to parse the response from handle_upstream_data to check its status code. The thing is, when I try to do it, the application just stops to work and nothing happens. Is there anything that I miss?

Here is my code:

def handle_upstream_data(self, raw: memoryview) -> None:
        logger.debug("Creating the Response Parser...")
        response = HttpParser(httpParserTypes.RESPONSE_PARSER)
        logger.debug("Parsing the upstream data...")
        response.parse(raw) # It runs forever
        logger.debug(
            "HTTP Response status code: %d",
            int.from_bytes(response.code),
        )
        super().handle_upstream_data(raw)

Just the debug logs below...

@alexandresgf Can you share the contents of raw. Ideally, you must check for parser.state before considering that complete request has been received. But if .parse is running into in infinite loop, that smells like a bug. Can you please share the raw packet. Thank you!!!

Nevermind, I just was using it in a wrong way. As you said, I checked the state and now everything works!

The final code:

def handle_upstream_data(self, raw: memoryview) -> None:
    logger.debug("Creating the Response Parser...")
    response = HttpParser(httpParserTypes.RESPONSE_PARSER)
    logger.debug("Parsing the upstream data...")
    response.parse(raw)

    if response.is_complete:
        logger.debug(
            "Response completed with status code %s",
            response.code,
        )

    super().handle_upstream_data(raw)

Thanks!
