This makes 'guix package' et al. slightly less verbose, by not emitting
"@ substituter-started" lines and similar.
* guix/scripts/build.scm (set-build-options-from-command-line): Pass
#:print-build-trace.
(%default-options): Add 'print-build-trace?'.

This partly reverts commit 185f669 ("services: Make sure the store's
group is the build group.")
* gnu/services/base.scm (guix-service)[activate]: Remove 'chown' call.
Add 'id' field to 'user-group' form.
* guix/build/install.scm (directives): Set the store's GID to 30000.
Before that the effect would be to re-create groups at each boot, and
thus remove any members of the groups.
* guix/build/activation.scm (activate-users+groups): Call 'add-group'
only when (getgrname name) fails.
* gnu/services/base.scm (guix-service)[activate]: New variable. Add
'chown' call for (%store-prefix). Set the 'activate' field to

performance.

containing most of the former 'operating-system-boot-script'.

* guix/build/install.scm (install-grub): Call 'error' if 'system*'
returns non-zero.
* guix/build/vm.scm (initialize-partition-table): Make 'partition-size'
a positional parameter. Call 'error' when 'system*' returns
non-zero'.

when S contains one of %NEWLINES.

the procedure name as the first argument to 'throw'.

handler for 'gcry-error.

Likewise.
* guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp):
Likewise.
Fixes <http://bugs.gnu.org/17312>.
* guix/scripts/authenticate.scm (guix-authenticate): Add calls to

copying files over when VOLATILE-ROOT? is true.
* gnu/system/linux-initrd.scm (expression->initrd): Add #:inputs
parameter.
[files-to-copy]: New procedure.
[builder]: Add 'to-copy' parameter; honor it.

Fixes situations where the remote 'guix build' is invoked before the
.drv has been completely copied, as reported at
<https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00174.html>.
In some cases 'send-files' would return before the other end is done
importing the files, and so the subsequent 'guix build' invocation would
just miss the .drv file it refers to.
* guix/utils.scm (call-with-decompressed-port): Don't close PORT.
(call-with-compressed-output-port): Likewise.
* tests/utils.scm ("compressed-output-port + decompressed-port"): Adjust
accordingly.
* guix/scripts/offload.scm (send-files): Add explicit (close-pipe pipe)
call.
(retrieve-files): Likewise.
Prevents garbage collection of the temporary store directory while
restoring a file set, as it could previously happen:
<https://lists.gnu.org/archive/html/guix-devel/2014-04/msg00167.html>.

[builder]: Use 'scandir' and remove all the files starting with
%GC-ROOT-FILE.
(transfer-and-offload): Adjust to renaming; remove
'false-if-exception' wraps.
Partially fixes <http://bugs.gnu.org/17212>.
* guix/utils.scm (errno): Move definition of 'bv' outside of the
procedure. Use 'bytevector-s32-native-ref' or
'bytevector-s64-native-ref' instead of 'bytevector-sint-ref'.
Problem reported by John Darrington <john@darrington.wattle.id.au>.
* guix/nar.scm (write-file): Filter out "." and ".." from the result of
'scandir'. Previously we did this by passing a suitable predicate.

whereby 'ensure-acl' would yield a wrong-type-arg error.
* guix/scripts/archive.scm (authorize-key): Use 'write-acl'.
Before that, there was a small time window during which the GC could
wipe the .drv (before 'guix build' has been called), or the build
result (before 'retrieve-files' has started.)

honor it.

call to 'offload' or 'retrieve-files'.
(send-files): Call 'remote-pipe' with #:quote? #f.
(retrieve-files): Likewise.
* guix/build/union.scm: Rewrite; only 'file=?' remains unchanged. Remove
'tree-union' and 'delete-duplicate-leaves' exports. Merge inputs in a
breadth-first fashion. Follow symlinks for purposes of making decisions
about the merge.

* guix/scripts/package.scm (search-path-environment-variables)[manifest-entry->package]:

* guix/scripts/substitute-binary.scm (guix-substitute-binary) <--query>:
Cache the result of (current-acl); pass it to 'valid-narinfo?' calls.
This saves 12% wall-clock time for "guix build emacs -n".
* guix/nar.scm (restore-file-set)[assert-valid-signature]: Rewrite in
terms of 'signature-case'.
* guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp):

instead of 'bandwidth' around 'send-files' calls, and 'download' lock
around 'retrieve-files' call.
* guix/scripts/offload.scm (remote-pipe): Remove '-z' lsh command line
argument. This makes transfers almost an order of magnitude slower.
OpenSSH's ssh(1) man page notes: "Compression is desirable on modem lines
and other slow connections, but will only slow down things on fast
networks." See also
<http://www.spikelab.org/blog/transfer-largedata-scp-tarssh-tarnc-compared.html>.
* guix/build/download.scm (http-fetch)[post-2.0.7?]: Use

a pipeline.
