From 49e6291a7a257f89f01644423f1b685778b8862a Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Thu, 23 Jan 2014 23:48:34 +0100 Subject: Add 'guix offload' as a daemon build hook. * nix/nix-daemon/guix-daemon.cc (GUIX_OPT_NO_BUILD_HOOK): New macro. (options): Add '--no-build-hook'. (parse_opt): Handle it. (main)[HAVE_DAEMON_OFFLOAD_HOOK]: Set 'useBuildHook' by default. Set $NIX_BUILD_HOOK to our offload hook unless otherwise specified. [!HAVE_DAEMON_OFFLOAD_HOOK]: Clear 'useBuildHook'. * pre-inst-env.in: Set and export NIX_BUILD_HOOK. * nix/scripts/offload.in, guix/scripts/offload.scm: New files. * guix/ui.scm (show-guix-help)[internal?]: Add "offload". * config-daemon.ac: Call 'GUIX_CHECK_UNBUFFERED_CBIP'. Instantiate 'nix/scripts/offload'. Set 'BUILD_DAEMON_OFFLOAD' conditional, and optionally define 'HAVE_DEAMON_OFFLOAD_HOOK' cpp macro. * daemon.am (nodist_pkglibexec_SCRIPTS)[BUILD_DAEMON_OFFLOAD]: Add it. * Makefile.am (MODULES)[BUILD_DAEMON_OFFLOAD]: Add 'guix/scripts/offload.scm'. (EXTRA_DIST)[!BUILD_DAEMON_OFFLOAD]: Likewise. * m4/guix.m4 (GUIX_CHECK_UNBUFFERED_CBIP): New macro. * doc/guix.texi (Setting Up the Daemon): Move most of the body to... (Build Environment Setup): ... this. New subsection. (Daemon Offload Setup): New subsection. --- nix/nix-daemon/guix-daemon.cc | 23 ++++++++++++++++++++++- nix/scripts/offload.in | 11 +++++++++++ 2 files changed, 33 insertions(+), 1 deletion(-) create mode 100644 nix/scripts/offload.in (limited to 'nix') diff --git a/nix/nix-daemon/guix-daemon.cc b/nix/nix-daemon/guix-daemon.cc index cf87e39354..d35b1cd076 100644 --- a/nix/nix-daemon/guix-daemon.cc +++ b/nix/nix-daemon/guix-daemon.cc @@ -1,5 +1,5 @@ /* GNU Guix --- Functional package management for GNU - Copyright (C) 2012, 2013 Ludovic Courtès + Copyright (C) 2012, 2013, 2014 Ludovic Courtès This file is part of GNU Guix. @@ -67,6 +67,7 @@ builds derivations on behalf of its clients."; #define GUIX_OPT_CHROOT_DIR 10 #define GUIX_OPT_LISTEN 11 #define GUIX_OPT_NO_SUBSTITUTES 12 +#define GUIX_OPT_NO_BUILD_HOOK 13 static const struct argp_option options[] = { @@ -94,6 +95,8 @@ static const struct argp_option options[] = "Perform builds as a user of GROUP" }, { "no-substitutes", GUIX_OPT_NO_SUBSTITUTES, 0, 0, "Do not use substitutes" }, + { "no-build-hook", GUIX_OPT_NO_BUILD_HOOK, 0, 0, + "Do not use the 'build hook'" }, { "cache-failures", GUIX_OPT_CACHE_FAILURES, 0, 0, "Cache build failures" }, { "lose-logs", GUIX_OPT_LOSE_LOGS, 0, 0, @@ -159,6 +162,9 @@ parse_opt (int key, char *arg, struct argp_state *state) case GUIX_OPT_NO_SUBSTITUTES: settings.useSubstitutes = false; break; + case GUIX_OPT_NO_BUILD_HOOK: + settings.useBuildHook = false; + break; case GUIX_OPT_DEBUG: verbosity = lvlDebug; break; @@ -226,6 +232,21 @@ main (int argc, char *argv[]) settings.substituters.clear (); settings.useSubstitutes = true; +#ifdef HAVE_DAEMON_OFFLOAD_HOOK + /* Use our build hook for distributed builds by default. */ + settings.useBuildHook = true; + if (getenv ("NIX_BUILD_HOOK") == NULL) + { + std::string build_hook; + + build_hook = settings.nixLibexecDir + "/guix/offload"; + setenv ("NIX_BUILD_HOOK", build_hook.c_str (), 1); + } +#else + /* We are not installing any build hook, so disable it. */ + settings.useBuildHook = false; +#endif + argp_parse (&argp, argc, argv, 0, 0, 0); if (settings.useSubstitutes) diff --git a/nix/scripts/offload.in b/nix/scripts/offload.in new file mode 100644 index 0000000000..50faed31c0 --- /dev/null +++ b/nix/scripts/offload.in @@ -0,0 +1,11 @@ +#!@SHELL@ +# A shorthand for "guix offload", for use by the daemon. + +if test "x$GUIX_UNINSTALLED" = "x" +then + prefix="@prefix@" + exec_prefix="@exec_prefix@" + exec "@bindir@/guix" offload "$@" +else + exec guix offload "$@" +fi -- cgit v1.2.3
