From 6ef61cc4c30e94acbd7437f19c893f63a7112267 Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 15 Oct 2018 22:40:35 +0200 Subject: daemon: Support multiplexed build output. This allows clients to tell whether output comes from the daemon or, if it comes from a builder, from which builder it comes. The latter is particularly useful when MAX-BUILD-JOBS > 1. * nix/libstore/build.cc (DerivationGoal::tryBuildHook) (DerivationGoal::startBuilder): Print the child's PID in "@ build-started" traces. (DerivationGoal::handleChildOutput): Define 'prefix', pass it to 'writeToStderr'. * nix/libstore/globals.cc (Settings:Settings): Initialize 'multiplexedBuildOutput'. (Settings::update): Likewise. * nix/libstore/globals.hh (Settings)[multiplexedBuildOutput]: New field. Update 'printBuildTrace' documentation. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0.163. * nix/nix-daemon/nix-daemon.cc (performOp) : Special-case "multiplexed-build-output" and remove "use-ssh-substituter". * guix/store.scm (set-build-options): Add #:multiplexed-build-output? and honor it. (%protocol-version): Bump to #x163. * tests/store.scm ("multiplexed-build-output"): New test. fixlet --- nix/nix-daemon/nix-daemon.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'nix/nix-daemon') diff --git a/nix/nix-daemon/nix-daemon.cc b/nix/nix-daemon/nix-daemon.cc index 782e4acfc5..2939422172 100644 --- a/nix/nix-daemon/nix-daemon.cc +++ b/nix/nix-daemon/nix-daemon.cc @@ -594,7 +594,7 @@ static void performOp(bool trusted, unsigned int clientVersion, if (name == "build-timeout" || name == "build-max-silent-time" || name == "build-max-jobs" || name == "build-cores" || name == "build-repeat" - || name == "use-ssh-substituter") + || name == "multiplexed-build-output") settings.set(name, value); else settings.set(trusted ? name : "untrusted-" + name, value); -- cgit v1.2.3
