    6. Appendix A: Detecting byte order in memory-safe languages

    +
    +

    Some programming languages such as Go don’t offer a way to serialize data in the +native byte order of the machine they’re running on without resorting to tricks +involving the unsafe package.

    +

    The following technique can be used (and will not be broken by changes to i3) to +detect the byte order i3 is using:

    +
      +
    1. +

      +The byte order dependent fields of an IPC message are message type and + payload length. +

      +
        +
      • +

        +The message type RUN_COMMAND (0) is the same in big and little endian, so + we can use it in either byte order to elicit a reply from i3. +

        +
      • +
      • +

        +The payload length 65536 + 256 (0x00 01 01 00) is the same in big and + little endian, and also small enough to not worry about memory allocations + of that size. We must use payloads of length 65536 + 256 in every message + we send, so that i3 will be able to read the entire message regardless of + the byte order it uses. +

        +
      • +
      +
    2. +
    3. +

      +Send a big endian encoded message of type SUBSCRIBE (2) with payload [] + followed by 65536 + 256 - 2 SPACE (ASCII 0x20) bytes. +

      +
        +
      • +

        +If i3 is running in big endian, this message is treated as a noop, + resulting in a SUBSCRIBE reply with payload {"success":true} +
        [A small payload is important: that way, we circumvent dealing + with UNIX domain socket buffer sizes, whose size depends on the + implementation/operating system. Exhausting such a buffer results in an i3 + deadlock unless you concurrently read and write, which — depending on the + programming language — makes the technique much more complicated.]
        . +

        +
      • +
      • +

        +If i3 is running in little endian, this message is read in its entirety due + to the byte order independent payload length, then + silently + discarded due to the unknown message type. +

        +
      • +
      +
    4. +
    5. +

      +Send a byte order independent message, i.e. type RUN_COMMAND (0) with + payload nop byte order detection. padding:, padded to 65536 + 256 bytes + with a (ASCII 0x61) bytes. i3 will reply to this message with a reply of + type COMMAND (0). +

      +
        +
      • +

        +The human-readable prefix is in there to not confuse readers of the i3 log. +

        +
      • +
      • +

        +This messages serves as a synchronization primitive so that we know whether + i3 discarded the SUBSCRIBE message or didn’t answer it yet. +

        +
      • +
      +
    6. +
    7. +

      +Receive a message header from i3, decoding the message type as big endian. +

      +
        +
      • +

        +If the message’s reply type is COMMAND (0), i3 is running in little + endian (because the SUBSCRIBE message was discarded). Decode the message + payload length as little endian, receive the message payload. +

        +
      • +
      • +

        +If the message’s reply type is anything else, i3 is running in big endian + (because our big endian encoded SUBSCRIBE message was answered). Decode + the message payload length in big endian, receive the message + payload. Then, receive the pending COMMAND message reply in big endian. +

        +
      • +
      +
