Hi,

You can find some information about it here:

https://bird.network.cz/?get_doc&v=20&f=prog-2.html#ss2.10

I think (IMHO) the reason why it is not implemented as "length+text" is because for that you need to prepare the whole response in some buffer first to calculate its size. In the current approach you can put the things out without the intermediate buffer.

Regards,
Alexander

I don’t think so.
In fact, nothing wrong, just wondering the reason.

LIU,

Can the use case be covered by SNMPd agentx support?

I want to implement an application to talk to bird daemon, basically like birdc/birdcl.
The control socket is TCP stream, it is fine. But the response from bird daemon adds some headers for each line
I understand server want to make a boundary/delimiter for stream. Just wondering why not just add how many bytes in the beginning of response, instead of this inconvenient way (have to decode line by line). I am not question bird implementation, just wondering ☺

Current format like below

Show protocols
0001 BIRD 2.0.10 ready.
2002-Name       Proto      Table      State  Since         Info
1002-device1    Device     ---        up
 static_bgp     Static     master4    up
 kernel1        Kernel     master4    up
0000
