2019-10-16daemon: Make 'profiles/per-user' non-world-writable....Fixes <https://bugs.gnu.org/37744>. Reported at <https://www.openwall.com/lists/oss-security/2019/10/09/4>. Based on Nix commit 5a303093dcae1e5ce9212616ef18f2ca51020b0d by Eelco Dolstra <edolstra@gmail.com>. * nix/libstore/local-store.cc (LocalStore::LocalStore): Set 'perUserDir' to #o755 instead of #o1777. (LocalStore::createUser): New function. * nix/libstore/local-store.hh (LocalStore): Add it. * nix/libstore/store-api.hh (StoreAPI): Add it. * nix/nix-daemon/nix-daemon.cc (performOp): In 'wopSetOptions', add condition to handle "user-name" property and honor it. (processConnection): Add 'userId' parameter. Call 'store->createUser' when userId is not -1. * guix/profiles.scm (ensure-profile-directory): Note that this is now handled by the daemon. * guix/store.scm (current-user-name): New procedure. (set-build-options): Add #:user-name parameter and pass it to the daemon. * tests/guix-daemon.sh: Test the creation of 'profiles/per-user' when listening on a TCP socket. * tests/store.scm ("profiles/per-user exists and is not writable") ("profiles/per-user/$USER exists"): New tests. Ludovic Courtès
2019-10-16daemon: Remove traces of 'NIX_ROOT_FINDER'....This is a followup to 2e3e5d21988fc2cafb2a9eaf4b00976ea425629d. * build-aux/test-env.in: Remove mentions of 'NIX_ROOT_FINDER'. * nix/libstore/gc.cc (LocalStore::collectGarbage): Adjust comment accordingly. Ludovic Courtès
2019-09-28daemon: Strictly respect timeouts for 'guix offload'....Until now it was up to 'guix offload' to honor timeouts. Unfortunately it would sometimes fail to do that, for example due to the libssh bug at <https://bugs.libssh.org/T33>. With this change, 'guix offload' is automatically killed by the daemon when one of the timeouts expires. Thus, data transfers performed by 'guix offload' now count as part of the timeouts, rather than just actual build time. * nix/libstore/build.cc (DerivationGoal::tryBuildHook): Pass true as the 'respectTimeouts' argument to 'childStarted'. Ludovic Courtès

2019-09-08daemon: Run 'guix substitute' directly and assume a single substituter....The daemon had a mechanism that allows it to handle a list of substituters and try them sequentially; this removes it. * nix/scripts/substitute.in: Remove. * nix/local.mk (nodist_pkglibexec_SCRIPTS): Remove. * config-daemon.ac: Don't output 'nix/scripts/substitute'. * nix/libstore/build.cc (SubstitutionGoal)[subs, sub, hasSubstitute]: Remove. [tryNext]: Make private. (SubstitutionGoal::SubstitutionGoal, SubstitutionGoal::init): Remove now unneeded initializers. (SubstitutionGoal::tryNext): Adjust to assume a single substituter: call 'amDone' upfront when we couldn't find substitutes. (SubstitutionGoal::tryToRun): Adjust to run 'guix substitute' via 'settings.guixProgram'. (SubstitutionGoal::finished): Call 'amDone(ecFailed)' upon failure instead of setting 'state' to 'tryNext'. * nix/libstore/globals.hh (Settings)[substituters]: Remove. * nix/libstore/local-store.cc (LocalStore::~LocalStore): Adjust to handle a single substituter. (LocalStore::startSubstituter): Remove 'path' parameter. Adjust to invoke 'settings.guixProgram'. Don't refer to 'run.program', which no longer exists.

(LocalStore::querySubstitutablePathInfos): Likewise, and remove 'substituter' parameter. * nix/libstore/local-store.hh (RunningSubstituter)[program]: Remove. (LocalStore)[runningSubstituters]: Remove. [runningSubstituter]: New field. [querySubstitutablePathInfos]: Remove 'substituter' parameter. [startSubstituter]: Remove 'substituter' parameter. * nix/nix-daemon/guix-daemon.cc (main): Remove references to 'settings.substituters'. * nix/nix-daemon/nix-daemon.cc (performOp): Ignore the user's "build-use-substitutes" value when 'settings.useSubstitutes' is false.

(DerivationGoal::tryBuildHook): Remove reference to 'NIX_BUILD_HOOK'. * nix/nix-daemon/guix-daemon.cc (main) [HAVE_DAEMON_OFFLOAD_HOOK]: Don't set 'NIX_BUILD_HOOK'. * nix/nix-daemon/nix-daemon.cc (performOp) [!HAVE_DAEMON_OFFLOAD_HOOK]: Leave 'settings.useBuildHook' unchanged.

Run "guix gc --list-busy". * nix/local.mk (nodist_pkglibexec_SCRIPTS): Remove 'scripts/list-runtime-roots'. * config-daemon.ac: Don't output nix/scripts/list-runtime-roots. * build-aux/pre-inst-env.in: Don't set 'NIX_ROOT_FINDER'. Set 'GUIX'. * doc/guix.texi (Invoking guix gc): Document '--list-busy'. * guix/scripts/gc.scm (show-help, %options): Add "--list-busy". (guix-gc)[list-busy]: New procedure.

Ludovic Courtès
2019-02-06daemon: Emit a 'build-succeeded' event in check mode....Until now, something like "guix build sed -v1 --check" would not get a 'build-succeeded' event, which in turn meant that the spinner would not be erased upon build completion. * nix/libstore/build.cc (DerivationGoal::registerOutputs): When 'buildMode' is bmCheck and 'settings.printBuildTrace' emit a "@ build-succeeded" trace upon success. * tests/store.scm ("build-succeeded trace in check mode"): New test.
