guix, branch v1.4.0rc2

deduplicate: Use 'sendfile' only with file ports.

2022-12-10T17:13:39+00:00

Fixes a regression introduced in b129026e2e242e9068158ae6e6fcd8d7c5ea092e.

* guix/store/deduplication.scm (dump-file/deduplicate): Use 'sendfile'
only when INPUT' is a file port.

install: 'umount-cow-store' retries upon EBUSY.

2022-12-10T13:34:35+00:00

Possibly fixes .

* gnu/build/install.scm (umount*): New procedure.
(unmount-cow-store): Use it instead of 'umount'.

installer: Detect mapped installation devices.

2022-12-10T10:23:27+00:00

Fixes: 

* gnu/installer/parted.scm (mapped-device?,
mapped-device-parent-partition): New procedures.
(eligible-devices): Detect mapped installation devices using the new
procedures.

deduplicate: Use 'sendfile' for small file copies.

2022-12-10T09:56:48+00:00

* guix/store/deduplication.scm (dump-file/deduplicate): Use 'sendfile'
instead of 'dump-port'.
* tests/store-deduplication.scm ("copy-file/deduplicate, below %deduplication-minimum-size"):
New test.

installer: Print progress bars and such as soon as \r is read.

2022-12-09T16:49:22+00:00

Fixes .

Previously progress bars and related things would be buffered by
'run-external-command-with-line-hooks' until \n is read.

* gnu/installer/utils.scm (run-external-command-with-line-hooks): Use
'read-delimited' rather than 'get-line'.  Pass 'concat as the last
argument.
(%display-line-hook): Remove.
(run-command): Use 'display' instead of '%display-line-hook'.
(%syslog-line-hook): Add "\n" when LINE doesn't end in \n.
(%installer-log-line-hook): Do not add an extra newline.
(installer-log-line): Add an extra newline.

services: nscd: Use nscd from 'glibc-final' on native builds.

2022-12-09T15:43:25+00:00

This reduces the closure size of systems by removing one glibc
copy--namely (@ (gnu packages base) glibc) in addition to (@ (gnu
packages commencement) glibc-final).

* gnu/services/base.scm ()[glibc]: Change default
value to use 'let-system' and 'canonical-package' as appropriate.

system: Remove unused yggdrasil OS template.

2022-12-09T15:40:53+00:00

This file was added in fe1cd098d2b83737e96f19438612291f5a9316e4 but it's
not referenced from anywhere, not even gnu/local.mk.  Furthermore, we
don't normally add full OS examples for the purposes of illustrating the
use of a single service.

* gnu/system/examples/yggdrasil.tmpl: Remove.

environment: '-C' doesn't throw when the NSS is dysfunctional.

2022-12-09T08:59:53+00:00

Previously, if the name service switch was dysfunctional, as can happen
on foreign distros lacking nscd, "guix shell -C" would crash with a
backtrace on the uncaught 'getpwuid' exception.  To address that, catch
the exception and deal with it gracefully.

Reported by remsd1 on #guix.

* guix/scripts/environment.scm (launch-environment/container): Wrap
'getpwuid' call in 'false-if-exception'.

guix-install.sh: Authorize all project build farms at once.

2022-12-09T08:59:32+00:00

* etc/guix-install.sh (sys_authorize_build_farms):
Iterate over all hosts.
