It is, instead you use a loop to read the whole message:

msg = ''
while true:
   data = recv(blocksize)   # or whatever
   msg += data
   if len(data) < blocksize: break   # end of data

Hopefully the sender sends them one at a time! Or at least
your message protocol stipulates that they are sent one
at a time(or in a stipulated amount, or that the number
of objects is specified in the message. Whatever it
takes for you to decode the received bytes.

Servers stipulate their API. If clients don't abide by
the API that's their problem not the servers!
