Subject: How to determine when to stop receiving pack content
Date: Sat, 10 Aug 2019 23:47:22 +0000	[thread overview]
Message-ID: <c1754835efe3aa8a5ac93ee2db4a99c5@farhan.codes> (raw)

Hi,

I am trying to write an implementation of git clone over ssh and am a little confused how to determine a server response has ended. Specifically, after a client sends its requested 'want', the server sends the pack content over. However, how does the client know to stop reading data? If I run a simple read() of the file descriptor:

A. If I use reading blocking, the client will wait until new data is available, potentially forever.
B. If I use non-blocking, the client might terminate reading for new data, when in reality new data is in transit.

I do not see a mechanism to specify the size or to indicate the end of the pack content. Am I missing something?

Thanks
