The function vl_socket_read_ready did contain some comments already,
but as they stated, the logic has to be tricky to cover multiple cases.
Comment:
+ Add function-level comment
+ Add comments to describe some of local variables
+ Add many comments to describe internal state at particular lines.
Simplify:
+ Remov mbp_set as it is never needed.
+ Replace msg_len with msgbuf_len to save "+ sizeof (msgbuf_t)".
Improve:
+ Early exit on EAGAIN.
Fix:
+ "n" now only tracks input_buffer.
Previously, it was entering the detection of additional messages
even for unprocessed_input.
+ Set up msg_buffer (including appending to unprocessed_input)
outside full-message-detection loop now,
so it cannot be executed multiple times as before.
Type: fix
