The WebSocket data stream code for stocks initially encountered significant issues related to message unpacking and dispatching. These issues stemmed from improperly handled nested lists and incomplete message processing, which led to frequent errors and unreliable data handling. To address this, the _unpack_message method was revised to ensure that nested lists are properly flattened. This change guarantees that all incoming messages are correctly unpacked and that each message is processed in its entirety, eliminating errors that occurred when dealing with complex message structures.
Another critical improvement involved the management of message buffers. In the original implementation, the buffer was not adequately managed, leading to problems with incomplete message handling and potential data loss. The _consume method was updated to include robust buffer management, ensuring that the buffer extends as new data arrives and clears appropriately after messages are processed. This enhancement prevents the accumulation of partial messages and ensures that each new message is processed from a clean state, thereby improving the reliability and accuracy of data handling in the WebSocket stream.
Additionally, the dispatching of messages was refined to handle lists of messages recursively. The original method struggled with processing lists of messages, often resulting in errors and missed data. By enhancing the _dispatch method to handle these lists recursively, the code now correctly processes nested message structures, ensuring that each message is dispatched and handled appropriately. This change, combined with the removal of debug print statements to streamline the code and enhance performance, significantly improves the overall reliability and functionality of the WebSocket data stream for stocks.
