Get nix store ping to work

tshaynik commented 1 year ago

This PR:

renames init_connection to process_connection. In the nix codebase, initConnection is the name of client function, while processConnection (in src/libstore/daemon.cc) is the daemon function that more closely resembles what we're replicating
closely follow the nix implementation of processConnection
Send the magic STDERR_LAST u64 back to the client (otherwise the connection will hang)
Add all STDERR constants from the nix worker protocol as an enum.
Adds a short section to the README explaining how to invoke the binary with nix store ping

Nice! Looks like there's some magic going on with stderr that we'll need to understand. Can you explain it to us on Monday?
