That way it is handled in the same way as other helper scripts.
* nix/scripts/guix-authenticate.in: Rename to...
* nix/scripts/authenticate.in: ... this.
* config-daemon.ac: Adjust accordingly.
* nix/local.mk (libstore_a_CPPFLAGS): Remove -DOPENSSL_PATH.

"PATH".

(LocalStore::exportPath, LocalStore::importPath): Use it instead of
'runProgram' and OPENSSL_PATH.
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'.

'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) <wopSetOptions>: Special-case
"multiplexed-build-output" and remove "use-ssh-substituter".

and honor it.
(%protocol-version): Bump to #x163.

'perform-download'.

honor it.
(url-fetch): Likewise.
* nix/libstore/builtins.cc (builtinDownload): Set _NIX_OPTIONS
environment variable.
* nix/libstore/build.cc (canBuildLocally): Allow building armhf-linux
builds on aarch64-linux.
(DerivationGoal::runChild) Throw error if attempting to build for
armhf-linux on an unsupported platform.
* doc/guix.texi (Invoking guix build): Document how to build natively
for armhf-linux on aarch64-linux. Add note that on some aarch64
machines this is unsupported.
* config-daemon.ac: Don't bail out when libbz2 is missing. Define
'HAVE_LIBBZ2' Automake conditional.
* nix/libstore/build.cc: Wrap relevant bits in '#if HAVE_BZLIB_H'.
* nix/libstore/globals.cc (Settings::Settings): 'logCompression'
defaults to COMPRESSION_GZIP when HAVE_BZLIB_H is false.

conditional on HAVE_BZLIB_H.
* nix/local.mk (guix_register_LDADD, guix_daemon_LDADD): Add -lbz2 only
when HAVE_LIBBZ2.
* nix/nix-daemon/guix-daemon.cc (parse_opt): Ignore "bzip2" when not
HAVE_BZLIB_H.

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'.
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.
Fixes <http://bugs.gnu.org/25242>.
Reported by Leo Famulari <leo@famulari.name>.
The regression was introduced in 94d92c7796.
* nix/libstore/build.cc (DerivationGoal::startBuilder): Set 'useChroot'
as a function 'of isBuiltin(drv)'.
(DerivationGoal::runChild): Use 'useChroot' instead of
'useChroot && !isBuiltin(drv)'.
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.
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'.
In particular, this eliminates a bunch of boilerplate code.

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.
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.
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

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().
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.

(DerivationGoal::outputsSubstituted): Ditto.
(DerivationGoal::inputsRealised): Ditto.

[timedOut]: New method.
(SubstitutionGoal::cancel): Remove.
(SubstitutionGoal::timedOut): New method.

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.

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.
