tokio-websockets - Case 7.1.6 : Informational - 11 ms @ 2025-05-21T14:33:43.317Z
Case Description
Send 256K message followed by close then a ping
Case Expectation
Case outcome depends on implementation defined close behavior. Message and close frame are sent back to back. If the close frame is processed before the text message write is complete (as can happen in asynchronous processing models) the close frame is processed first and the text message may not be received or may only be partially recieved.
Case Outcome
Actual events differ from any expected.
Expected:
{'OK': [('message', u'Hello World!', False)], 'NON-STRICT': []}
Observed:
[('message', u'BAsd7&jh23BAsd7&jh23BAsd7&jh23BAsd7&jh23BAsd7&jh23BAsd7&jh23BAsd ...', False), ('message', u'Hello World!', False)]
Case Closing Behavior
Connection was properly closed (INFORMATIONAL)

| Key | Value | Description |
| isServer | True | True, iff I (the fuzzer) am a server, and the peer is a client. |
| closedByMe | True | True, iff I have initiated closing handshake (that is, did send close first). |
| failedByMe | False | True, iff I have failed the WS connection (i.e. due to protocol error). Failing can be either by initiating closing handshake or brutal drop TCP. |
| droppedByMe | True | True, iff I dropped the TCP connection. |
| wasClean | True | True, iff full WebSocket closing handshake was performed (close frame sent and received) _and_ the server dropped the TCP (which is its responsibility). |
| wasNotCleanReason | None | When wasClean == False, the reason what happened. |
| wasServerConnectionDropTimeout | False | When we are a client, and we expected the server to drop the TCP, but that didn't happen in time, this gets True. |
| wasOpenHandshakeTimeout | False | When performing the opening handshake, but the peer did not finish in time, this gets True. |
| wasCloseHandshakeTimeout | False | When we initiated a closing handshake, but the peer did not respond in time, this gets True. |
| localCloseCode | 1000 | The close code I sent in close frame (if any). |
| localCloseReason | None | The close reason I sent in close frame (if any). |
| remoteCloseCode | 1000 | The close code the peer sent me in close frame (if any). |
| remoteCloseReason | None | The close reason the peer sent me in close frame (if any). |
