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.
This makes it easier to run the uninstalled daemon.
* nix/local.mk (libstore_a_CPPFLAGS): Append "/guix" to
NIX_LIBEXEC_DIR.
* build-aux/pre-inst-env.in (NIX_LIBEXEC_DIR): Adjust comment.
* nix/libstore/builtins.cc (builtinDownload): Remove SUBDIR and its
use.
* nix/libstore/local-store.cc (runAuthenticationProgram): Ditto.

* nix/nix-daemon/guix-daemon.cc (main): Ditto.
* nix/nix-daemon/nix-daemon.cc (performOp) <wopSetOptions>: When
'isRemoteConnection' is true, set 'settings.keepFailed' to zero.
* doc/guix.texi (Common Build Options): Document this behavior.
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.
(nodist_libexec_SCRIPTS): Remove.
(nodist_pkglibexec_SCRIPTS): New variable.
* nix/nix-daemon/guix-daemon.cc (main): Remove 'setenv' call for
"PATH".
* nix/libstore/local-store.cc (runAuthenticationProgram): New function.
(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'.
* nix/libstore/globals.cc (Settings:Settings): Initialize
'multiplexedBuildOutput'.
(Settings::update): Likewise.

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.
* tests/store.scm ("multiplexed-build-output"): New test.
fixlet
This code has never been of any use in Guix.
* nix/libutil/archive.cc (useCaseHack): Remove.
(parse): Keep only the alternate branch in "if (useCaseHack)".
* guix/scripts/perform-download.scm (perform-download): Add
#:print-build-trace? and pass it to 'url-fetch'.
(guix-perform-download): Define 'print-build-trace?' and pass it to
'perform-download'.
* guix/build/download.scm (ftp-fetch): Add #:print-build-trace? and

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.
* nix/nix-daemon/nix-daemon.cc (isRemoteConnection): New variable.
(performOp): For wopCollectGarbage, throw an error when isRemoteConnection
is set.
(acceptConnection): Set isRemoteConnection when connection is not AF_UNIX.
* tests/guix-daemon.sh: Add a test for the new behavior.
* 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.
* nix/libstore/globals.hh (CompressionType): Make 'COMPRESSION_BZIP2'
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.
Fixes <https://bugs.gnu.org/29862>.
Reported by Danny Milosavljevic <dannym@scratchpost.org>.
* nix/scripts/list-runtime-roots.in (canonicalize-store-item): Define
'store' with a trailing "/". Have the 'string-prefix?' call match the
'string-drop' call.
This allows running as non-root.
Fixes a regression introduced in b8f59cdc20.
* nix/scripts/list-runtime-roots.in (referenced-files): Handle EACCES in
addition to ENOENT.
Looking at 'addAdditionalRoots' in libstore/gc.cc, it looks like it
should always have been this way. In practice it probably doesn't make
much of a difference.
* nix/scripts/list-runtime-roots.in (canonicalize-store-item): New
procedure.
<top level>: Use it.
This makes things a bit faster (0.8s instead of 1.4s on my laptop).
* nix/scripts/list-runtime-roots.in (lsof-roots): Remove.
(proc-fd-roots): Return the empty list when 'scandir' returns #f.
(referenced-files): New procedure.
Use it at the top level.
Prior to this change, errors such as wrong permissions on
/etc/guix/signing-key.sec would give:
guix-daemon: nix/libutil/serialise.cc:15: virtual nix::BufferedSink::~BufferedSink(): Assertion `!bufPos' failed.
This patch correctly propagates the error to the client and thus changes
that to:
error: build failed: file `/etc/guix/signing-key.sec' should be secret (inaccessible to everybody else)!
* nix/nix-daemon/nix-daemon.cc (performOp): Wrap 'exportPath' call in
'try' block.

* nix/nix-daemon/nix-daemon.cc (acceptConnection): Remove intermediate
'inaddr' variables that relied on implicit casts. This fixes
compilation with GCC 4.9.
* nix/nix-daemon/guix-daemon.cc (DEFAULT_GUIX_PORT): New macro.
(listen_options): New variable.
(parse_opt): Push back '--listen' options to LISTEN_OPTIONS.
(open_unix_domain_socket, open_inet_socket)

(daemonLoop): Rewrite to take a vector of file descriptors, to select(2)
on them, and to call 'acceptConnection'.
(run): Change to take a vector of file descriptors.
* tests/guix-daemon.sh: Add test.
Otherwise, users will be stuck running an old copy of guix and the guix-daemon
if they copy the service files instead of symlinking them.
* etc/guix-daemon.conf.in, etc/guix-daemon.service.in, etc/guix-publish.conf.in,
etc/guix-publish.service.in: Expand @localstatedir@ instead of @bindir@.
* nix/local.mk (etc/guix-%.service, etc/guix-%.conf): Use @localstatedir@
instead of @bindir@.

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>.

"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.

Before that we'd have STDERR_WRITE round trips for very small amounts of
data, ranging from a few bytes for the metadata of nars to the size of
one file being exported.
With this change, something like:
guix archive --export /gnu/store/5rrsbaghh5ix1vjcicsl60gsxilhjnf2-coreutils-8.25 | dd of=/dev/null
reports a throughput of 35 MB/s instead of 25 MB/s before.
* nix/nix-daemon/nix-daemon.cc (TunnelSink): Inherit from 'BufferedSink'
rather than 'Sink'. Rename 'operator ()' to 'write'.
(performOp) <wopExportPath>: Add 'sink.flush' call.

* doc/guix.texi (Invoking guix publish): Add description for enabling
"guix publish" on host distros using the new files.
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

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.
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.

Preserve supplementary groups of build users
The following patch is an attempt to address this bug (see
<http://bugs.gnu.org/18994>) by preserving the supplementary groups of
build users in the build environment.
In practice, I would expect that supplementary groups would contain only
one or two groups: the build users group, and possibly the “kvm” group.

Allow substitutes for builds that have preferLocalBuild set
Not substituting builds with "preferLocalBuild = true" was a bad idea,
because it didn't take the cost of dependencies into account. For
instance, if we can't substitute a fetchgit call, then we have to
download/build git and all its dependencies.
Partially reverts 5558652709 and adds a
new derivation attribute "allowSubstitutes" to specify whether a
derivation may be substituted.
