There have been a few patches to the mailing list lately
not respecting this, and this linter detects 630 package

package transformation.

This reverts commit fd62b4cf88, which
would lead 'GUIX_PACKAGE_PATH' to be ignored for instance when using
'guix build -f file.scm', as shown by 'tests/guix-build.sh'.
This reduces the number of syscalls for:
env -i $(type -P strace) -c $(type -P guix) help
from 4.3K to 2.2K, thereby reducing startup time.

(run-guix): ... here.
It has been reported in IRC, that directories may show up multiple times in
subdirs.el, probably a result of propagation. This can for instance be seen
by ‘guix environment --ad-hoc emacs emacs-guix’, which will generate multiple
references to dash. With this patch only one reference per package is
generated.
* guix/profiles.scm (emacs-subdirs): wrap subdirs added to
‘normal-top-level-add-to-load-path’ in ‘delete-duplictes’.
* guix/import/go.scm (go-package-description): Make sure description* is
always a list, so the result is properly matched.

package.json records two hashes of package.tgz, which change for each

Before this change, the system value would be passed as x86_64 when using a
i686-linux emulated system, e.g.:
$ guix environment --system=i686-linux --ad-hoc guile -- \
guile -c '(display (utsname:machine (uname))) (newline)'
x86_64
This change uses the Guile builtin %host-type variable, which doesn't have
this problem:
$ guix environment --system=i686-linux --ad-hoc guile -- \
guile -c '(display %host-type) (newline)'
i686-unknown-linux-gnu

A side effect of c47f3fc135 is that
(@ (guix describe) current-profile) provides the correct answer when the
'guix' package is installed in a profile. Consequently, the 'guix'
package installed in /run/current-system/profile (for instance) would
end up loading all the .scm files in that directory.
* guix/describe.scm (current-channel-entries): Remove ENTRY if it lacks
the 'source' property.
When running:
guix environment --ad-hoc gnome --no-grafts --search-paths
this reduces wall-clock time by ~5%. The number of object cache lookups
goes down from 96K to 89K. (Note that 'gnome' is an interesting example
because it has many propagated inputs, which themselves have propagated
inputs too, which would lead to a long input list and a long manifest in
the 'profile-derivation' gexp.)
* guix/profiles.scm (profile-derivation)[inputs, search-paths]: Remove.
[extra-inputs]: New variable.
[builder]: Adjust call to 'build-profile'.
* guix/build/profiles.scm (manifest-sexp->inputs+search-paths): New
procedure.
(build-profile): Remove 'inputs' parameter; make 'manifest' the 2nd
positional parameter and add #:extra-inputs. Call
'manifest-sexp->inputs+search-paths' to obtain 'inputs' and
'search-paths'.

Previously, the mtime of CACHE-DIRECTORY may or may not have been
updated after a pull. Thus, 'maybe-remove-expired-cache-entries' could
potentially delete CACHE-DIRECTORY right before it's returned.
* guix/git.scm (update-cached-checkout): Call 'utime' on CACHE-DIRECTORY.
Previously, '--with-latest' would wrongfully print:
warning: could not determine latest upstream release of 'xyz'
when 'xyz' is already the latest version. This fixes that.
* guix/transformations.scm (transform-package-latest): Use
'package-latest-release' instead of 'package-latest-release*'.
Partly fixes <https://bugs.gnu.org/41702>.
Reported by Lars-Dominik Braun <ldb@leibniz-psychology.org>.
Previously, 'graft-derivation' would start anew at every call. When
creating a profile with lots of packages, it would potentially do the
same work multiple times. The per-session cache addresses this. It
increases the derivation-graft-cache hit rate from 77.9% to 80.1% on:
GUIX_PROFILING="derivation-graft-cache" ./pre-inst-env \
guix environment --ad-hoc libreoffice inkscape krita darktable -n
The effect is more visible on the pathological case below, where cache
hit rate goes from 75% to 87% and wall-clock time from 5.0s to 3.5s:
GUIX_PROFILING="derivation-graft-cache" ./pre-inst-env \
guix environment --ad-hoc r-learnr --search-paths
* guix/grafts.scm (%graft-cache): New variable.
(graft-derivation): Add calls to 'store-connection-cache' and
'set-store-connection-cache!'.
This procedure lost its only user in commit
710854304b.
* guix/store.scm (references/substitutes): Remove.
* tests/store.scm ("references/substitutes missing reference info")
("references/substitutes with substitute info"): Remove.
The process-substitution procedure is opening two distinct connections. The
first one when looking for narinfo by calling lookup-narinfo and the other one
when fetching nar files.
Cache the connection when looking for narinfos so that process-substitution
only opens one connection.
* guix/scripts/substitute.scm (lookup-narinfo): Cache connection by using
open-connection-for-uri/cached.
* guix/lint.scm (check-tests-true): New linter.
(%local-checkers)[tests-true]: Add it.
* tests/lint.scm ("tests-true: #:tests? must not be set to #t")
("tests-true: absent #:tests? is acceptable")

When running:
GUIX_PROFILING="gc object-cache" ./pre-inst-env \

this reduces the number of object cache lookup from 115K to 96K, with a
slight CPU and memory usage reduction as well.

The procedure ‘which’ from (guix build utils)
is used for two different purposes:
1. for finding the absolute file name of a binary
that needs to run during the build process
2. for finding the absolute file name of a binary,
for the target system (as in --target=TARGET),
e.g. for substituting sh->/gnu/store/.../bin/sh,
python->/gnu/store/.../bin/python.
When compiling natively (target=#f in Guix parlance),
this is perfectly fine.
However, when cross-compiling, there is a problem.
"which" looks in $PATH for binaries. That's good for purpose (1),
but incorrect for (2), as the $PATH contains binaries from native-inputs
instead of inputs.
This commit defines a ‘search-input-file’ procedure. It functions
like 'which', but instead of searching in $PATH, it searches in
the 'inputs' of the build phase, which must be passed to
‘search-input-file’ as an argument. Also, the file name must
include "bin/" or "sbin/" as appropriate.
* guix/build/utils.scm (search-input-file): New procedure.

Previously, when creating new wrappers, 'wrap-program' would search
for an interpreter to use in PATH. However, this is incorrect when
cross-compiling. Allow overriding the shell interpreter to use,
via an optional keyword argument #:sh.
In time, when all users of 'wrap-program' have been corrected,
this keyword argument can be made mandatory.
* guix/build/utils.scm (wrap-program): Introduce a #:sh keyword
argument, defaulting to (which "sh"). Use this keyword argument.

Reported by Maxim Cournoyer.
* guix/gnu-maintenance.scm (latest-html-release)[url->release]: Adjust

The default Guile web server implementation supports the keep alive
mechanism. However, in our custom http-write implementation, the connection
is unconditionally close after sending nar files.
To prevent that, when supported, add the client port to the server poll set so
that further requests can be handled without closing the connection.
* guix/scripts/publish.scm (nar-response-port): Rename it into ...
(nar-compressed-port): ... this procedure. Operate directly on a given PORT.
(http-write): Add keep-alive support when sending nar files.
* guix/scripts/substitute.scm (process-substitution): Pass the download size
to the progress-report-port procedure so that it doesn't block reading from
the input port when keep-alive is supported.
The Guile web server is reading the response connection header to decide
whether to close the connection. However, as the request connection header is
not forwarded to the response, this mechanism cannot work.
* guix/scripts/publish.scm (add-extra-headers): New procedure.
(make-request-handler): Use it to forward the request connection header to the
response.
In some cases, running "guix upgrade" can trigger this warning, and
"missing arguments" is misleading then.

This allows computing a manifest for a specific system. Previously this was
possible, but only through changing %current-system, which caused the
derivation to be computed using that system as well (so computing a derivation
for aarch64-linux on x86_64-linux would require running aarch64-linux code).
This new argument adds the possibility of computing derivations for non-native
systems, without having to run non-native code.
I'm looking at this as it will enable the Guix Data Service to compute channel
instance derivations without relying on QEMU emulation for non-native
systems (it should be faster as well).

Users (both old and new) struggling with locale warnings is a recurrent theme;
part of it may be due to the glibc-utf8-locales package being misleading, as
