* guix/status.scm (<build>): Define using
'define-immutable-record-type', and add 'set-build-completion' binding.
(update-build)[set-completion]: Remove.
Use 'set-build-completion' instead.
Previously the progress bar wouldn't be erased by the time the next
"building foo" line would be printed.
* guix/status.scm (print-build-event)[erase-current-line*]: New
procedure.
Call it instead of (display "\r").
Previously it would refer to
/var/guix/profiles/per-user/root/current-guix/bin/guix, which would fail
when that profile does not exist. This is notably the case when using
'channel-instance->package' as done in commit
7e6d8d366a.
* gnu/packages/package-management.scm (guix-daemon)[arguments]: In
'install phase, honor environment variable 'GUIX'.
* guix/self.scm (whole-package)[wrap]: New procedure.

Fixes a regression introduced in
0ea939fb79.
* guix/scripts/package.scm (process-query) <'list-available>: Change
#:superseded? to #:deprecated? since that's what
'fold-available-packages' passes.
* guix/status.scm (print-build-event)[report-build-progress]: New
procedure.
[print-log-line]: Add ID parameter. Call 'report-build-progress' when
appropriate.
Adjust callers.
* guix/status.scm (<build>): New record type.
(build, matching-build): New procedures.
(compute-status): Adjust to manipulate <build> records instead of
derivation file names in 'build-status-builds-completed' and
'build-status-building'.
(build-event-output-port)[process-line]: Use 'string-split' to preserve
spaces.
* tests/status.scm ("compute-status, builds + substitutes")
("compute-status, missing events"): Adjust to expect <build> records.
Produce complete "build-started" events.
("compute-status, multiplexed build output"): Likewise, and remove
"bar.drv" from 'builds-completed'.
Previously if ~/.config/guix/current/bin was in $PATH, we'd still
suggest to run 'hash guix' because we'd compare (which "guix") against
/var/guix/profiles/per-user/….
* guix/scripts/pull.scm (build-and-install): Check whether (which
"guix") matches PROFILE or its user-friendly variant.
* guix/packages.scm (package-input-rewriting): Allow REPLACEMENTS to be
a promise.
* gnu/packages/guile.scm (package-for-guile-2.0): Delay the first
argument to 'package-input-rewriting'.
Works around <https://bugs.gnu.org/34102>.
Reported by Marius Bakke <mbakke@fastmail.com>.
* guix/build/download.scm (tls-wrap): Add "-VERS-TLS1.3" to the priority
string when (gnutls-version) is not prefixed by "3.5".
Until now, private and generated packages (e.g., those created by
'texlive-union') we missing from the list passed to 'node-back-edges',
which would lead to inaccurate dependent counts.
Previously we'd get:
$ guix refresh -l texlive-fonts-cm
Building the following 80 packages would ensure 116 dependent packages
are rebuilt: …
Now we have:
$ Building the following 240 packages would ensure 597 dependent
packages are rebuilt: …
* guix/scripts/refresh.scm (list-dependents): Call 'package-closure'.
The skip "~*" argument was misplaced, leading the number of dependents
to be skipped (instead of the number of covering packages.) Thus, we'd
get:
$ guix refresh -l ocaml4.02-ppx-deriving@4.1
Building the following package would ensure 1 dependent packages are rebuilt: bap@1.3.0
instead of:
Building the following package would ensure 26 dependent packages are rebuilt: bap@1.3.0
* guix/scripts/refresh.scm (list-dependents): Move "~*" in the right
place, to skip (length covering) rather than (length dependents).
Fixes a regression in 'guix pack -R' introduced with commit
c2dcff41c2. The imported modules of
'c-compiler' would be compiled in this order: first (guix records),
then (guix search-paths). Consequently,
'report-duplicate-field-specifier' would be reported as unbound while
compiling (guix search-paths), leading to a build failure.
* guix/records.scm (report-invalid-field-specifier)
(report-duplicate-field-specifier): Move within 'eval-expand'.
Fixes a regression introduced in
c2dcff41c2, whereby many tests in
'tests/packages.scm' would trigger a syntax error due to duplicate field
intializers in forms like:
(dummy-package "foo" (version "0"))
* guix/tests.scm (dummy-package, dummy-origin): Rewrite to inherit from
a base record. This restores the semantics from before
c2dcff41c2.
* tests/services.scm ("instantiate-missing-services, indirect"): Remove
duplicate 'extensions' field.
Until now we'd get things like:
guix build: error: build failed: build of `/gnu/store/….drv' failed
or:
$ guix gc -d /sdf
guix gc: error: build failed: path `/sdf' is not in the store
which is kinda ridiculous.
* guix/ui.scm (call-with-error-handling): Remove "build failed:" prefix
for 'store-protocol-error?'.
This is because (gnu tests docker) depends on (guix scripts pack).
* guix/self.scm (compiled-guix)[*system-test-modules*]: Add dependency
on *CLI-MODULES*.
* guix/records.scm (report-duplicate-field-specifier): New procedure.
(make-syntactic-constructor): Call it.
* tests/records.scm ("define-record-type* & duplicate initializers"):
New test.

Previous warnings and errors such as those raised by (guix records)
would not be displayed during the load phase.

This ensures that channel modules are compiled with the right Guile,
that they get to see the right modules, and so on. IOW, it avoids bugs
such as those addressed by commits
3c0e16391e and
cb341c1219.
* guix/channels.scm (standard-module-derivation): Add 'core'
parameter. Rewrite in terms of 'gexp->derivation-in-inferior'.
(build-from-source): Add #:core parameter and pass it to
'standard-module-derivation'.
(build-channel-instance): Add 'core' parameter and pass it on.
(channel-instance-derivations)[dependencies]: Remove.
Adjust 'build-channel-instance' call.
Previously the imported modules and extensions of EXP would be missing
from the load path of 'guix repl'.
* guix/inferior.scm (gexp->derivation-in-inferior)[script]: New
variable.
[trampoline]: Write (primitive-load #$script) to PIPE. Add #$output.
* tests/channels.scm ("channel-instances->manifest")[depends?]: Check
for requisites rather than direct references.
Adjust callers accordingly.
Previous 'channel-instance->manifest' would call
'latest-channel-derivation', which could trigger another round of
'latest-repository-commit' for no good reason.
* guix/channels.scm (resolve-dependencies): New procedure.
(channel-instance-derivations)[edges]: New variable.
[instance->derivation]: New procedure.
* tests/channels.scm (make-instance): Use 'checkout->channel-instance'
instead of 'channel-instance'.

* guix/build/profiles.scm (build-etc/profile): When 'OUTPUT/etc/profile'
already exists, delete it first.
(build-profile): Likewise for 'OUTPUT/manifest'.
* tests/profiles.scm ("profile in profile"): New test.

It is possible to generate a profile where this hook will crash, as the
texmf.cnf file does not exist to be patched by substitute*. A simple example

This new procedure uses BLKRRPART to determine whether or not a device is
busy. It is useful when a device does not appear as mounted but is maybe used

example.
* guix/build/syscalls.scm (device-in-use?): New exported procedure.
* gnu/installer.scm: Rename to ...
* gnu/installer/record.scm: ... this.
* gnu/installer/build-installer.scm: Move everything to the build side and
rename to gnu/installer.scm.
* gnu/installer/newt.scm: Remove all the gexps and add depencies to newt
modules as this code will only be used on the build side by now.
* gnu/local.mk (GNU_SYSTEM_MODULES): Adapt it,
(dist_installer_DATA): New rule to install installer's aux-files.
* gnu/system/install.scm (%installation-services): Use only
'installer-program' from (gnu installer). The installer is now choosen on the
build side.
* guix/self.scm (*system-modules*): Restore previous behaviour and add all
installer files to #:extra-files field of the scheme-node.
* po/guix/POTFILES.in: Adapt it.
As we do not want to add a dependency to newt and the graphical installer
in (guix self), do not install (gnu system install).
* guix/self.scm (*system-modules*): Remove (gnu system install) from
"guix-system" scheme-node.
* guix/import/github.scm (updated-github-url): Return the unchanged source URI
for packages using git-fetch.
[updated-url]: Do not handle URIs which end with ".git".
* gnu/packages.scm (fold-available-packages): New procedure.
* guix/scripts/package.scm (process-query): Use it instead of
'fold-packages'.
* tests/packages.scm ("fold-available-packages with/without cache"):

That way 'guix edit' doesn't need to load any package module.
* gnu/packages.scm (find-package-locations, specification->location):

This fixes a regression introduced in
f1de676ea8 since %DEFAULT-OPTIONS was
missing the 'debug key that 'set-build-options-from-command-line'
expects.
* guix/scripts/copy.scm (show-help, %options): Add '--verbosity'.
(%default-options): Rename 'verbosity' to 'debug'. Add
'print-build-trace?', 'print-extended-build-trace?',
'multiplexed-build-output?', and 'verbosity'.
(guix-copy): Wrap body in 'with-status-verbosity'.
The previous '--verbosity' option was misleading and rarely what users
were looking for. The new option provides a consistent way to choose
whether or not to display the build log.
* guix/scripts/build.scm (show-build-options-help): Remove "--verbosity"
and add "--debug".
(set-build-options-from-command-line): Use the 'debug key of OPTS for
#:verbosity.
(%standard-build-options): Change "verbosity" to "debug". Use
'string->number*' instead of 'string->number'.
(%default-options): Change 'verbosity to 'debug and add a 'verbosity
key.
(show-help): Add '--verbosity'.
(%options): Likewise, and change '--quiet' to set the 'verbosity key of
RESULT.
(guix-build): Use 'with-status-verbosity' instead of parameterizing
CURRENT-BUILD-OUTPUT-PORT, honor the 'verbosity key of OPTS, and remove
'quiet?'.
* guix/scripts/environment.scm (show-help, %options): Add '--verbosity'.
(%default-options): Add 'debug'.
(guix-environment): Honor the 'verbosity key of OPTS.
* guix/scripts/pack.scm (%default-options): Add 'debug.
(%options, show-help): Add '--verbosity'.
(guix-pack): Honor the 'verbosity key of OPTS.
* guix/scripts/package.scm (%default-options): Add 'debug.
(show-help, %options): Add '--verbosity'. Mark '--verbose' as

'set-build-options-from-command-line.
* doc/guix.texi (Common Build Options): Document '--verbosity' and
'--debug'.
(Additional Build Options): Adjust description of '--quiet'.
This allows us to combine '--recursive' with other options (-u, -m,
etc.), turns off warnings when '--recursive' is used, and avoids the
hazards of I/O in the presence of multithreading.
* guix/scripts/refresh.scm (options->packages): New procedure, with code
formerly in 'guix-refresh'.
(refresh-recursive): Remove.
(guix-refresh)[keep-newest, core-package?, args-packages, packages]:
Remove.
[warn?]: Set to #f when RECURSIVE? is true.
Call 'options->packages' in monadic context.
* guix/scripts/lint.scm (check-github-url): Warn only if the GitHub URI
obtained after following redirects is not same as the original URI.
* tests/lint.scm ("github-url: already the correct github url"): New test.

This is a followup to 5923102f7b.
* guix/scripts/pull.scm (show-help): Add '--system'.
This removes two elements from %LOAD-PATH and %LOAD-COMPILED-PATH of the
'guix' command and thus further reduces the number of 'stat' calls it
makes.
* guix/gexp.scm (load-path-expression): Return #f when MODULES and
EXTENSIONS are both empty.
(gexp->script): Don't emit anything when SET-LOAD-PATH is #f.
This halves the number of elements in %LOAD-PATH and %LOAD-COMPILED-PATH
and halves the number of 'stat' calls as reported by:
env -i $(type -P guix) build -e '(@ (gnu packages base) coreutils)' -nd
* guix/self.scm (node-source+compiled, guile-module-union): New
procedures.
(guix-command): Remove 'compiled-modules' parameter. Remove
'source-directories' and 'object-directories' variables and add
'module-directory'. Change command so that it adds nothing but
MODULE-DIRECTORY to %LOAD-PATH and %LOAD-COMPILED-PATH.
(whole-package): Remove #:compiled-modules. Assume MODULES contains
'share/guile/site' and 'lib/guile' and adjust code accordingly.
(compiled-guix): When PULL-VERSION is 1, use 'node-source+compiled'
only. Remove #:compiled-modules argument to 'whole-package'.
* guix/channels.scm (whole-package-for-legacy): Add 'module+compiled'
and pass it to 'whole-package'.
Previously we would rely on auto-compilation of all the Guix modules.
The complete evaluation would take ~15mn on berlin.guixsd.org and
require lots of RAM. This approach should be faster since potentially
only part of the modules are rebuilt. Furthermore, as a side-effect, it
builds the derivations that 'guix pull' uses.
* build-aux/hydra/gnu-system.scm: Remove 'eval-when' form.
(hydra-jobs): New procedure.
* gnu/ci.scm (package->alist, qemu-jobs, system-test-jobs)
(tarball-jobs): Return strings for the 'license' field.
* guix/self.scm (compiled-guix)[*cli-modules*]: Add (gnu ci).
This allows the fallback code in (guix git-download) to actually run.

* guix/build/git.scm (git-fetch): Guard against 'invoke-error?' and
really return #f upon failure.
Fixes a bug whereby "guix build -f file.scm -s SYSTEM" would not honor
SYSTEM when 'file.scm' returns a gexp or a file-like object.
* guix/scripts/build.scm (options->derivations): Pass #:system to
'run-with-store' in the 'file-like?' and 'gexp?' cases.
* guix/import/github.scm (updated-github-url): Respond with the repository url
for the 'git-fetch' fetch method.
(github-package?): Simplify boolean expression.
(github-repository, github-user-slash-repository): Strip trailing ".git" from
project if present.
(latest-release)<origin-github-uri>: Recognize a 'git-reference'.
This extra level of locking turned out to be unnecessary.
* guix/scripts/offload.scm (with-machine-lock): Remove.
(machine-lock-file): Remove.
(acquire-build-slot): Remove surrounding 'with-machine-lock'.
This lock was unnecessary and it led to a contention when many 'guix
offload' processes are polling for available machines.
* guix/scripts/offload.scm (machine-choice-lock-file): Remove.
(choose-build-machine): Remove surrounding 'with-file-lock (machine-lock-file)'.
This is a followup to ed7b44370f71126087eb953f36aad8dc4c44109f;
following that commit, 'guix offload test' and 'guix offload status'
would abort with a backtrace instead of clearly diagnosing a missing
'guix' command on the build machine.
* guix/scripts/offload.scm (assert-node-has-guix): Call 'leave' when
NODE is not an inferior. Remove 'catch' blocks for 'node-repl-error'.
(check-machine-availability): Invoke 'assert-node-has-guix' first.
(check-machine-status): Print a warning when 'remote-inferior' returns #f.
Using inferiors and thus 'guix repl' simplifies setup on build
machines (no need to worry about GUILE_LOAD_PATH etc.)
Furthermore, the 'guix repl -t machine' protocol running in a remote
pipe addresses several issues with the current implementation of nodes
and RREPLs in Guile-SSH: fewer round trips, doesn't leave a 'guile
--listen' process behind it, stateless (since a new process is started
each time), more efficient (the SSH channel can be reused), more
reliable (no 'pgrep', 'pkill', and shellology; see
<https://github.com/artyom-poptsov/guile-ssh/issues/11> as an example.)
* guix/ssh.scm (inferior-remote-eval): New procedure.
(send-files): Use it instead of 'make-node' and 'node-eval'.

(assert-node-can-import, assert-node-can-export): Likewise, and add
'session' parameter.
(check-machine-availability): Likewise, and add calls to
'close-inferior' and 'disconnect!'.
(check-machine-status): Likewise.
* doc/guix.texi (Daemon Offload Setup): Remove bit related to 'guile' in
$PATH and $GUILE_LOAD_PATH; mention 'guix' alone.
* guix/scripts/refresh.scm (refresh-recursive, list-transitive): New

* tests/lint.scm ("github-url", "github-url: one suggestion"): New tests.
Fixes a regression introduced in
bbe66a530a whereby the actual

* guix/scripts/offload.scm (check-machine-status): Add call to

This should avoid "database is locked" errors when there's a lot of
concurrency, for instance when offloading simultaneously a lot of
builds.
* guix/store/database.scm (call-with-database): Add two 'sqlite-exec'
calls to set 'journal_mode' and 'busy_timeout'.
Previously, if a remote build would fail due to lack of disk space, this
would be considered a permanent failure and thus cached as a build
failure if the local daemon runs with '--cache-failures'.
* guix/scripts/offload.scm (transfer-and-offload): Upon
'nix-protocol-error?' call 'node-free-disk-space' and return 1 instead
of 100 if the result if lower than 10 MiB.

* guix/scripts/offload.scm (machine-load): Remove.
(node-load, normalized-load): New procedures.
(choose-build-machine): Call 'open-ssh-session' and 'make-node' from

(check-machine-status): Use 'node-load' instead of 'machine-load'. Call
'disconnect!' on SESSION.
* guix/import/cran.scm (fetch-description): Return #F on failure.
(cran->guix-package): Retry from CRAN on failure to fetch description from
bioconductor.
The previous caching strategy, which used STORE as an 'eq?' key, would
no longer work when the functional cache is used because subsequent
store values are not 'eq?'.
* guix/download.scm (built-in-builders*): Rewrite in terms of

Previously we'd use the (sequence M (map P L)) idiom just because 'mapm'
was slower (not specialized for the given monad). This is no longer the
