Hello Alan,
I am trying to change the network protocol to use GPB. The way I am doing
this is,
1. Building network message using protocol buffer class, NetworkMsg.
2. Serialize the NetworkMsg to string, using GPB serialization API,
SerializeToString(string *output).
3. Sending it using send()
4. On receiving side, parsing string back to NetworkMsg using GPB parsing
API, ParseFromString(const string& data)
I am not getting this to work for following reasons,
- The SerializeToString(string *output) API serializes the message
and stores the bytes in the given string. The bytes are
binary and may have "\0". The send function uses
add_to_output_buffer(const char* msg, unsigned int size) function. This
function works on null-terminated c string and may endup removing data.
- The receiving side of the message separates messages using "\n" but GPB
serialized strings have many "\n". So on the receiving
side I am not able to Parse the string back to NetworkMsg.
Do you have any suggestions on how to move forward without having to do
major changes in existing code.
Thanks,
Shilpa Sodani.
