It simply takes one more round-trip to negotiate.

And libcurl probably will not support websockets even in long run. I've been searching for a websocket implementation for git and finally settled for netcat-like programs, sitting in front of git and dealing with network just like ssh. It will be the simplest way to add either websocket or http/2 support. If either protocol gets popular enough, smart-http can become a fall-back mechanism where performance does not matter much. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
