Fixes <http://bugs.gnu.org/18526>.
Reported by Mark H. Weaver.
* guix/build/download.scm (tls-wrap): Add 'server' parameter. Call
'set-session-server-name!' when (gnutls) defines it.
(open-connection-for-uri): Adjust 'tls-wrap' call accordingly.
* guix/scripts/offload.scm (machine-less-loaded?, machine-faster?):
Remove.
(machine-power-factor): New procedure.
(machine-less-loaded-or-faster?): Use it.
* guix/scripts/pull.scm (unpack): Remove 'store' parameter. Rewrite
using 'gexp->derivation'.
(what-to-build, indirect-root-added, build-and-install): New
procedures.
(guix-pull): Use it.
* guix/build/syscalls.scm (network-interfaces): Update docstring.
(%interface-line): New variable.
(all-network-interfaces): New procedure.
* tests/syscalls.scm ("all-network-interfaces"): New test.
("network-interfaces"): Change to make sure the result is a subset
of (all-network-interfaces).
Previously 'guix pull' would just fail with "No such file or directory"
if ~/.config didn't already exist.
* guix/ui.scm (config-directory): Use 'mkdir-p' instead of 'mkdir'.
Change the 'catch' handler to expect errors different from EEXIST.
* guix/build/utils.scm (wrap-program): Multiple invocations of
wrap-program for the same file create successive wrappers. Adjust
docstring.
* tests/build-utils.scm: Test new wrap-program behavior.
(%store): New variable.
* gnu/build/activation.scm (activate-current-system): Honor
$GUIX_NEW_SYSTEM by default.
* guix/scripts/system.scm (switch-to-system): Set $GUIX_NEW_SYSTEM
before loading SCRIPT.
Reported by Andreas Enge <andreas@enge.fr>.
* guix/profiles.scm (right-arrow): Use 'set-port-conversion-strategy!'
instead of '%default-port-conversion-strategy'. The latter is only
available in Guile 2.0.5.
* guix/gexp.scm (lower-reference-graphs): New procedure.
(gexp->derivation)[graphs-file-names]: New procedure.
Use 'lower-reference-graphs', and augment #:inputs argument as a
function of #:references-graphs.
* doc/guix.texi (G-Expressions): Adjust 'gexp->derivation' documentation
accordingly.
* tests/gexp.scm ("gexp->derivation, store copy"): Remove reference to
TWO in BUILD-DRV. Use TWO directly in #:references-graphs argument.
("gexp->derivation #:references-graphs"): New test.
* gnu/system/vm.scm (qemu-image): Remove variable 'graph'; use INPUTS as
the #:references-graphs argument to
'expression->derivation-in-linux-vm'.
* guix/build/pull.scm (report-build-progress): New procedure.
(p-for-each): Add #:progress parameter.
[loop]: Keep track of the number of completed processes. Tail-call
PROGRESS at each loop iteration.
(build-guix): Add #:debug-port parameter. Use it for verbose
messages. Change 'tar' flags to 'xf'. Around 'compile-file' call,
bind CURRENT-WARNING-PORT to DEBUG-PORT.
* guix/scripts/pull.scm (unpack): Add #:verbose? parameter.
[builder]: Pass #:debug-port to 'build-guix'.
(guix-pull): Leave CURRENT-BUILD-OUTPUT-PORT unchanged. Pass
#:verbose? to 'unpack'.
This allows editors to parse warnings correctly.
* guix/scripts/lint.scm (emit-warning): Use 'format' instead of
'warning', to avoid the "guix lint: " prefix in messages.
* tests/lint.scm (call-with-warnings): Indent.
* guix/profiles.scm (manifest-show-transaction)[package-strings,
upgrade-strings]: Show version number in separate column. Show OUTPUT
in first column, and only when it's different from "out".
* guix/profiles.scm (manifest-lookup): New procedure.
(manifest-installed?): Use it.
(manifest-transaction-effects): Return a pair of entries for upgrades.
(right-arrow): New procedure.
(manifest-show-transaction)[upgrade-string, →]: New variables.
Report upgrades using 'upgrade-string'.
* tests/profiles.scm ("manifest-show-transaction"): New test.
("manifest-transaction-effects"): Match UPGRADE against a pair.
Before that, 'guix package --search-paths' would not work if, say,
'foo-0.2' is installed but the distro provides 'foo-0.3'.
* guix/scripts/package.scm (search-path-environment-variables)[manifest-entry->package]:
Handle the case where 'find-best-packages-by-name' returns '().
* guix/profiles.scm (manifest-transaction-effects): New procedure.
(manifest-show-transaction): Use it instead of locally computing it.
* tests/profiles.scm (glibc): New variable.
("manifest-transaction-effects"): New test.
Fixes <http://bugs.gnu.org/18115>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/scripts/offload.scm (register-gc-root)[script]: Wrap 'symlink'
call in "catch 'system-error", and ignore EEXIST errors.
Fixes <http://bugs.gnu.org/18070>.
Reported by Andreas Enge <andreas@enge.fr>.
* guix/scripts/offload.scm (remote-pipe): Augment docstring.
(machine-load): Return +inf.0 instead of 1 if MACHINE does not respond
or responds badly.
* guix/build-system/perl.scm (perl-build): Add support for variables
parallel-build? and parallel-tests?.
* guix/build-system/gnu.scm (gnu-build): Add a line break for clarity.
