* guix/scripts/environment.scm (%options): Remove "--exec", which was
deprecated in commit 1de2fe95e0 in 2015.
* tests/guix-environment.sh: Remove use of '-E'.
This minimizes the risk of locale-related warnings, at least for those
who use one of the bundled UTF-8 locales.
* guix/self.scm (guix-command)[glibc-utf8-locales]: New variable.
In program body, set GUIX_LOCPATH.
* guix/scripts/environment.scm (purify-environment): Add 'white-list'
parameter and honor it.
(create-environment): Add #:white-list parameter and honor it.
(launch-environment): Likewise.
(launch-environment/fork): Likewise.
(show-help, %options): Add '--inherit'.
(guix-environment): Define 'white-list' and pass it to
'launch-environment/fork'.
* tests/guix-environment.sh: Test '--inherit'.
* doc/guix.texi (Invoking guix environment): Document it.
Previously 'guix system switch-generation' or 'delete-generations' would
yield a GRUB menu where entries for old generations were in the wrong
order (i.e., oldest first.)
* guix/scripts/system.scm (reinstall-bootloader): Reverse the list
returned by 'generation-numbers'.
* guix/scripts/pull.scm (new/upgraded-packages): OLD no longer stores
all the versions of each package. Remove 'vhash-fold*' call and reduce
the number of 'version>?' calls when computing UPGRADED.
* guix/scripts/pull.scm (new/upgraded-packages): New procedure, with
code formerly in 'display-new/upgraded-packages'.
(display-new/upgraded-packages): Use it.
* guix/scripts/pull.scm (display-profile-news): Use
'fold-available-packages' instead of 'fold-packages' to compute OLD.
(profile-package-alist): Use 'inferior-available-packages'.
In practice the error was not triggered because
'package-transitive-propagated-inputs' currently returns the empty list
for these two packages.
* guix/scripts/pack.scm (gcrypt-sqlite3&co): Remove labels from the
result.
* gnu/system/vm.scm (gcrypt-sqlite3&co): Likewise.
Fixes <https://bugs.gnu.org/34402>.
Reported by <pkill9@runbox.com>.
Previously 'display-error' could be called with the wrong number of
arguments (e.g., for 'git-error' exceptions), and thus nothing at all
was displayed.
* guix/ui.scm (report-load-error): Check whether ARGS matches the
parameters for 'display-error' and call 'print-exception' otherwise.
'guix pull' was always doing it, and now '--with-branch' & co. will do
it as well.
* guix/git.scm (honor-system-x509-certificates!): New procedure.
(%certificates-initialized?): New variable.
(with-libgit2): Add call to 'honor-system-x509-certificates!'.
* guix/scripts/pull.scm (honor-x509-certificates): Call
'honor-system-x509-certificates!' and fall back to
'honor-lets-encrypt-certificates!'.
* guix/git.scm (<git-checkout>)[recursive?]: New field.
(latest-repository-commit*): Add #:recursive? and honor it.
(git-checkout-compiler): Honor the 'recursive?' field of CHECKOUT.
* guix/git.scm: Autoload (git submodule).
(url-cache-directory): Add #:recursive? and honor it.
(call-with-repository): New procedure.
(with-repository): New macro.
(update-submodules): New procedure.
(update-cached-checkout): Add #:recursive? and #:log-port and honor
them.
(latest-repository-commit): Add #:recursive? and honor it.
[dot-git?]: Recognize ".git" regular files when RECURSIVE? is true.
After a successful download, we'd erase the download-progress line, and
the end result would be two empty lines following the "downloading …"

no-op when PRINT-LOG? is true.
Move calls to 'erase-current-line*' to the 'build-succeeded' and
'build-failed' events.
Previously, "guix package -r something-not-installed" would silently
complete. Now an error is raised.
* guix/profiles.scm (&unmatched-pattern-error): New condition type.
(manifest-matching-entries): Rewrite to raise an error when one of
PATTERNS is not matched.
* guix/ui.scm (call-with-error-handling): Handle 'unmatched-pattern-error?'.
* tests/guix-package.sh: Add test.
* tests/profiles.scm ("manifest-matching-entries"): Don't try to remove
unmatched pattern.
("manifest-matching-entries, no match"): New test.
("manifest-transaction-effects"): Remove 'remove' field.
Fixes <https://bugs.gnu.org/27476>.
This fixes multi-threaded compilation of this code where syntax

lead a thread to see the "wrong" value of the syntax parameter.
* guix/monads.scm (define-syntax-parameter-once): New macro.
(>>=, return): Use it.
* guix/gexp.scm (define-syntax-parameter-once): New macro.
(current-imported-modules, current-imported-extensions): Use it.
janestreet reversionned its packages and prefixed them with "v". Let the
importer know about that and choose "v" versions first.
* guix/import/opam.scm (find-latest-version): Work around version
rewrite from janestreet.
(opam->guix-package): Do not pass "v" to version number.
* guix/status.scm (<build>)[phase]: New field.
(%phase-start-rx): New variable.
(update-build): Add clause to match %PHASE-START-RX and adjust the
'phase' field accordingly.
* tests/status.scm ("compute-status, build phase"): Add test
* 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'.

* 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.

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

[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.

* 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.

This fixes a regression introduced in
f1de676ea8 since %DEFAULT-OPTIONS was
missing the 'debug key that 'set-build-options-from-command-line'

* 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

(%standard-build-options): Change "verbosity" to "debug". Use
'string->number*' instead of 'string->number'.
(%default-options): Change 'verbosity to 'debug and add a 'verbosity

(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'.

(Additional Build Options): Adjust description of '--quiet'.
This allows us to combine '--recursive' with other options (-u, -m,

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.

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

* guix/import/github.scm (updated-github-url): Respond with the repository url

(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

* 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.

(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
