2017-02-07daemon: Define 'NIX_STORE' before invoking 'guix perform-download'.Ludovic Courtès
Reported by rohit yadav <rohityadav@utexas.edu> at <https://lists.gnu.org/archive/html/guix-devel/2017-02/msg00191.html>. This fixes a regression whereby 'guix perform-download' would always see NIX_STORE as unset and thus use "/gnu/store", leading it to miscompute the hydra.gnu.org content-addressed URLs when the store file name is not "/gnu/store". * nix/libstore/builtins.cc (builtinDownload): Add 'setenv' call for 'NIX_STORE'.
2017-01-15daemon: Client settings no longer override daemon settings.Ludovic Courtès
Fixes <http://bugs.gnu.org/20217>. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x161. * nix/nix-daemon/nix-daemon.cc (performOp): "build-max-jobs", "build-max-silent-time", and "build-cores" are no longer read upfront; instead, read them from the key/value list at the end. * nix/nix-daemon/guix-daemon.cc (main): Explicitly set 'settings.maxBuildJobs'. * guix/store.scm (%protocol-version): Bump to #x161. (set-build-options): #:max-build-jobs, #:max-silent-time, and #:build-cores now default to #f. Adjust handshake to new protocol. * tests/store.scm ("build-cores"): New test. * tests/guix-daemon.sh: Add test for default "build-cores" value.
2017-01-11daemon: Allow check builds of 'builtin:download' derivations.Ludovic Courtès
Fixes <http://bugs.gnu.org/25089>. Reported by Leo Famulari <leo@famulari.name>. * nix/libstore/build.cc (DerivationGoal::runChild): In the 'isBuiltin' case, check whether DRV's output is in 'redirectedOutputs', and pass an 'output' argument to the built-in builder. (DerivationGoal::addHashRewrite): Add 'printMsg' call. * nix/libstore/builtins.hh (derivationBuilder): Add 'output' parameter. * nix/libstore/builtins.cc (builtinDownload): Likewise. Add OUTPUT to ARGV. * guix/scripts/perform-download.scm (perform-download): Add 'output' parameter. (guix-perform-download): Adjust 'match' clauses accordingly. * tests/derivations.scm ("'download' built-in builder, check mode"): New test.
2016-12-29daemon: Allow fixed-output derivation builds with TMPDIR set.Ludovic Courtès
Fixes <http://bugs.gnu.org/25242>. Reported by Leo Famulari <leo@famulari.name>. The regression was introduced in 94d92c7796a3dd50c27d532315f7d497ac99f08e. * nix/libstore/build.cc (DerivationGoal::startBuilder): Set 'useChroot' as a function 'of isBuiltin(drv)'. (DerivationGoal::runChild): Use 'useChroot' instead of 'useChroot && !isBuiltin(drv)'.
2016-12-09daemon: Set ownership of kept build directories to the calling user.Hartmut Goebel
Fixes <http://bugs.gnu.org/15890>. * nix/libstore/globals.hh (Settings) Add clientUid and clientGid. * nix/nix-daemon/nix-daemon.cc (daemonLoop] Store UID and GID of the caller in settings. * nix/libstore/build.cc (_chown): New function. (DerivationGoal::deleteTmpDir): Use it, change ownership of build directory if it is kept and the new owner is not root.
2016-12-05daemon: Fix invalid Boost format string.Ludovic Courtès
* nix/libstore/optimise-store.cc (LocalStore::optimisePath_): Use %3% instead of %m, the latter being an invalid Boost format specifier.
2016-11-16daemon: Add 'built-in-builders' RPC.Ludovic Courtès
* nix/libstore/builtins.cc (builtinBuilderNames): New function. * nix/libstore/builtins.hh (builtinBuilderNames): New declaration. * nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x160.

(built-in-builders): New procedure. * tests/derivations.scm ("built-in-builders"): New test.
2016-11-16daemon: Add "builtin:download" derivation builder.Ludovic Courtès
This ensures that 1) the derivation doesn't change when Guix changes; 2) the derivation closure doesn't contain Guix and its dependencies; 3) we don't have to rely on ugly chroot hacks. Adapted from Nix commit 0a2bee307b20411f5b0dda0c662b1f9bb9e0e131. * nix/libstore/build.cc (DerivationGoal::runChild): Add special case for 'isBuiltin(drv)'. Disable chroot when 'isBuiltin(drv)'. * nix/libstore/builtins.cc, nix/libstore/builtins.hh, nix/scripts/download.in, guix/scripts/perform-download.scm: New files. * guix/ui.scm (show-guix-help)[internal?]: Add 'perform-download'. * nix/local.mk (libstore_a_SOURCES): Add builtins.cc. (libstore_headers): Add builtins.hh. (nodist_pkglibexec_SCRIPTS): Add 'scripts/download'. * config-daemon.ac: Emit 'scripts/download'. * Makefile.am (MODULES): Add 'guix/scripts/perform-download.scm'. * tests/derivations.scm ("unknown built-in builder") ("'download' built-in builder") ("'download' built-in builder, invalid hash") ("'download' built-in builder, not found") ("'download' built-in builder, not fixed-output"): New tests. Co-authored-by: Eelco Dolstra <eelco.dolstra@logicblox.com>
2016-10-28daemon: Do not error out when deduplication fails due to ENOSPC.Ludovic Courtès
This solves a problem whereby if /gnu/store/.links had enough entries, ext4's directory index would be full, leading to link(2) returning ENOSPC. * nix/libstore/optimise-store.cc (LocalStore::optimisePath_): Upon ENOSPC from link(2), print a message and return instead of throwing a 'SysError'.
2016-10-28daemon: Improve the SQLite wrapper API.Eelco Dolstra
In particular, this eliminates a bunch of boilerplate code. Also integrates these Nix commits: 80da7a6 Probably fix SQLITE_BUSY errors 37a337b throwSQLiteError(): Check for SIGINT so we don't loop forever Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2016-10-28daemon: Factor out SQLite handling.Eelco Dolstra

Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2016-06-26daemon: Rename 'NIX_CONF_DIR' to 'GUIX_CONFIGURATION_DIRECTORY'.David Craven
Partly fixes <http://bugs.gnu.org/22459>. Reported by Jeff Mickey <j@codemac.net> and David Craven <david@craven.ch>. * nix/libstore/globals.cc (Settings::processEnvironment()): Change 'NIX_CONF_DIR' to 'GUIX_CONFIGURATION_DIRECTORY'. * nix/local.mk (libstore_a_CPPFLAGS): Likewise. * guix/config.scm.in (%config-directory): Likewise. * build-aux/test-env.in: Likewise. * gnu/packages/patches/hydra-automake-1.15.patch: Likewise. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2016-05-31daemon: Substitute queries return immediately when substitutes are disabled.Ludovic Courtès
Reported by Federico Beffa <beffa@ieee.org> at <https://lists.gnu.org/archive/html/guix-devel/2016-05/msg00928.html>. * nix/libstore/local-store.cc (LocalStore::querySubstitutablePaths) (LocalStore::querySubstitutablePathInfos): Return when 'settings.useSubstitutes' is false. * tests/store.scm ("references/substitutes missing reference info"): Make sure to return #f on failure. * tests/store.scm ("substitutable-path-info when substitutes are turned off"): ("substitutable-paths when substitutes are turned off"): New tests.
2016-05-31daemon: Fix typo.Ludovic Courtès
Fixes a regression/typo introduced in e08380fb6cefd3fd67c3c220a3ddaf385e6413cf. * nix/libstore/build.cc (DerivationGoal::startBuilder): Canonicalize "/tmp", not "/tmp/guix-build".
2016-05-31daemon: rounds: Keep the differing output if -K is given.Eelco Dolstra
Regardless of -K, we now also print which output differs.
2016-05-31daemon: Canonicalize gids to 0.Eelco Dolstra
Previously files in the Nix store were owned by root or by nixbld, depending on whether they were created by a substituter or by a builder. This doesn't matter much, but causes spurious diffoscope differences. So use root everywhere.
2016-05-31daemon: check: Keep the differing output if -K is given.Eelco Dolstra
This makes it easier to investigate the non-determinism, e.g. $ nix-build pkgs/stdenv/linux -A stage1.pkgs.zlib --check -K error: derivation ‘/nix/store/l54i8wlw22656i4pk05c52ngv9rpl39q-zlib-1.2.8.drv’ may not be deterministic: output ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8’ differs from ‘/nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check’ $ diffoscope /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8 /nix/store/11a27shh6n2ivi4a7s964i65ql80cf27-zlib-1.2.8-check ... ├── lib/libz.a │ ├── metadata │ │ @@ -1,15 +1,15 @@ │ │ -rw-r--r-- 30001/30000 3096 Jan 12 15:20 2016 adler32.o ... │ │ +rw-r--r-- 30001/30000 3096 Jan 12 15:28 2016 adler32.o ...

2016-05-31daemon: check: Fix "failed to produce output path".Eelco Dolstra
This occured when sandbox building is disabled, at least one output exists, and at least one other output does not.
2016-05-31daemon: check: Fix assertion failure when some outputs are missing.Eelco Dolstra
E.g. $ nix-build pkgs/stdenv/linux/ -A stage1.pkgs.perl --check nix-store: src/libstore/build.cc:1323: void nix::DerivationGoal::tryToBuild(): Assertion `buildMode != bmCheck || validPaths.size() == drv->outputs.size()' failed. when perl.out exists but perl.man doesn't. The fix is to only check the outputs that exist. Note that "nix-build -A stage1.pkgs.all --check" will still give a (proper) error in this case.
2016-05-31daemon: When repairing, rebuild if there is no substituter.Eelco Dolstra
2016-05-31daemon: Fix --repair failure on multiple-output derivations.Eelco Dolstra
If repair found a corrupted/missing path that depended on a multiple-output derivation, and some of the outputs of the latter were not present, it failed with a message like error: path ‘/nix/store/cnfn9d5fjys1y93cz9shld2xwaibd7nn-bash-4.3-p42-doc’ is not valid Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2016-05-31daemon: ~PathLocks(): Handle exceptions.Eelco Dolstra
Otherwise, since the call to write a "d" character to the lock file can fail with ENOSPC, we can get an unhandled exception resulting in a call to terminate().
2016-05-31daemon: Handle /tmp being a symlink.Eelco Dolstra
* nix/libstore/build.cc (DerivationGoal::startBuilder): Call 'canonPath' on "/tmp".
2015-12-30daemon: Build in /tmp/guix-build-*.Ludovic Courtès
* nix/libstore/build.cc (DerivationGoal::startBuilder): Use "guix-build" instead of "nix-build" for TMPDIR. * doc/guix.texi (Build Environment Setup): Adjust accordingly.
2015-12-30daemon: Remove unused 'RemoteStore' class.Ludovic Courtès
* nix/libstore/remote-store.cc, nix/libstore/remote-store.hh: Remove. * nix/libstore/store-api.cc (readStorePath, readStorePaths): New functions, formerly in remote-store.cc. (openStore): Remove reference to 'RemoteStore'. * daemon.am (libstore_a_SOURCES): Remove remote-store.cc. (libstore_headers): Remote remote-store.hh.
2015-12-13daemon: Better distinguish build statuses.Eelco Dolstra
In Nix itself, the new 'BuildResult' type is returned by the new 'buildDerivation' method, which we don't have and need. * nix/libstore/build.cc (Goal)[cancel]: Remove. [timeOut]: New pure virtual method. (DerivationGoal)[result]: New field. [cancel]: Remove. [timedOut, getResult, done]: New methods. (DerivationGoal::cancel): Remove. (DerivationGoal::timedOut): New method. (DerivationGoal::haveDerivation): Call 'done' instead of 'amDone'. (DerivationGoal::outputsSubstituted): Ditto. (DerivationGoal::inputsRealised): Ditto. (DerivationGoal::buildDone): Ditto. (DerivationGoal::handleChildOutput): Call 'timedOut' instead of 'cancel'. (DerivationGoal::done): New method. (SubstitutionGoal)[cancel]: Remove. [timedOut]: New method. (SubstitutionGoal::cancel): Remove. (SubstitutionGoal::timedOut): New method. (Worker::waitForInput): Use it. * nix/libstore/store-api.hh (BuildResult): New struct. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2015-12-09daemon: Use deterministic $TMPDIR in chroot.Eelco Dolstra
Rather than using $<host-TMPDIR>/nix-build-<drvname>-<number>, the temporary directory is now always /tmp/nix-build-<drvname>-0. This improves bitwise-exact reproducibility for builds that store $TMPDIR in their build output. (Of course, those should still be fixed...) * nix/libstore/build.cc (DerivationGoal)[tmpDirInSandbox]: New field. (DerivationGoal::startBuilder): Initialize 'useChroot' earlier. Compute 'tmpDirInSandbox', and use it when populating 'dirsInChroot'. * doc/guix.texi (Build Environment Setup): Document it. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2015-12-08daemon: Allow builds to be repeated.Eelco Dolstra
This makes it easy to detect non-deterministic builds. * nix/libstore/build.cc (DerivationGoal): Remove 'InodesSeen'; add 'curRound', 'nrRound', and 'prevInfos'. (DerivationGoal::inputsRealised): Initialize 'nrRound'. (NotDeterministic): New error type. (DerivationGoal::buildDone): Check whether we need to repeat. (DerivationGoal::startBuilder): Adjust message. (DerivationGoal::registerOutputs): Check whether we get the same result. * nix/libstore/globals.cc (Settings::get(const string & name, int def)): New method. * nix/libstore/globals.hh (Settings): Add it. * nix/libstore/store-api.hh (ValidPathInfo): Add operator ==. * nix/nix-daemon/nix-daemon.cc (performOp): Allow "build-repeat" for "untrusted" users. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
2015-12-02daemon: Add 'buildMode' parameter to 'buildPaths' RPC.Ludovic Courtès
* 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.
2015-12-02daemon: optimizePath: Detect some .links corruptions.Eelco Dolstra
If automatic store optimisation is enabled, and a hard-linked file in the store gets corrupted, then the corresponding .links entry will also be corrupted. In that case, trying to repair with --repair or --repair-path won't work, because the new "good" file will be replaced by a hard link to the corrupted file. We can catch most of these cases by doing a sanity-check on the file sizes.
2015-12-02daemon: Filter build-chroot-dirs entries that conflict with derivation outputs.Eelco Dolstra
Fixes https://github.com/NixOS/nixpkgs/issues/9504. Note that this means we may have a non-functional /bin/sh in the chroot while rebuilding Bash or one of its dependencies. Ideally those packages don't rely on /bin/sh though.
2015-12-02daemon: Prevent .chroot from being GC'ed when using ↵Eelco Dolstra
