  "message": "Implement the no-done capability\n\nSmart HTTP clients may request both multi_ack_detailed and no-done in\nthe same request to prevent the client from needing to send a \"done\"\nline to the server in response to a server\u0027s \"ACK %s ready\".\n\nFor smart HTTP, this can save 1 full HTTP RPC in the fetch exchange,\nimproving overall latency when incrementally updating a client that\nhas not diverged very far from the remote repository.\n\nUnfortuantely this capability cannot be enabled for the traditional\nbi-directional connections.  multi_ack_detailed has the client sending\nmore \"have\" lines at the same time that the server is creating the\n\"ACK %s ready\" and writing out the PACK stream, resulting in some race\nconditions and/or deadlock, depending on how the pipe buffers are\nimplemented.  For very small updates, a server might actually be able\nto send \"ACK %s ready\", then the PACK, and disconnect before the\nclient even finishes sending its first batch of \"have\" lines.  This\nmay cause the client to fail with a broken pipe exception.  To avoid\nall of these potential problems, \"no-done\" is restricted only to the\nsmart HTTP variant of the protocol.\n\nChange-Id: Ie0d0a39320202bc096fec2e97cb58e9efd061b2d\nSigned-off-by: Shawn O.
