From 708d9070006fd46ffe4c2c3cf64154ea4430202a Mon Sep 17 00:00:00 2001
From: Ludovic Courtès <ludo@gnu.org>
Date: Wed, 2 Dec 2015 18:43:51 +0200
Subject: daemon: Add 'buildMode' parameter to 'buildPaths' RPC.
* nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x10f.
* nix/libstore/remote-store.cc (RemoteStore::buildPaths): Send the
BUILDMODE when the daemon supports it. Reject invalid values of
BUILDMODE for old daemons.
* nix/nix-daemon/nix-daemon.cc (performOp) <wopBuildPaths>: Read the
build mode when the client supports it.
