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'.
* guix/scripts/offload.scm (node-guile-version): New procedure.
(node-free-disk-space, transfer-and-offload, node-load)
(choose-build-machine, assert-node-has-guix): Use 'remote-inferior'
instead of 'make-node' and 'inferior-eval' instead of '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
procedures.
(show-help): Document it.
(guix-refresh): Add flags and checks for new options.
* doc/guix.texi (Invoking guix refresh): Document new options.
* gnu/services/messaging.scm (<quassel-configuration>): New record type.
(%quassel-account, %quassel-activation): New procedures.
(quassel-service-type): New variable.
* gnu/tests/messaging.scm (%test-quassel): New variable.
(run-quassel-test): New procedure.
* doc/guix.texi (Messaging): Document quassel service.
* gnu/packages/patches/file-CVE-2018-10360.patch: New file.
* gnu/packages/file.scm (file)[replacement]: New field.
(file/fixed): New variable.
* gnu/packages/commencement.scm (file-boot0): Use 'package/inherit' to
receive security fixes.
* gnu/local.mk (dist_patch_DATA): Register it.
* guix/scripts/lint.scm (check-github-uri): New procedure.
(%checkers): Add it.
* doc/guix.texi (Invoking guix lint): Document it.
* tests/lint.scm ("github-url", "github-url: one suggestion"): New tests.
The substitute for removing a failing test did no longer work since
the way the test is included changed in v5.45.0: Formerly the test
has listed, now there is a separate statement for this test.
* gnu/package/kde-frameworks.scm((baloo)[arguments]<#phases>: Change
substitute in phase 'remove-failing-test'.
* gnu/packages/maths.scm (z3): Update to 4.8.3.
[build-system]: Switch from cmake to make, and use the current
scripts/mk_make.py build script instead of the now-deprecated
contrib/cmake/bootstrap.py.

Fixes a regression introduced in
bbe66a530a whereby the actual
load (non-normalized) would be displayed.
* guix/scripts/offload.scm (check-machine-status): Add call to
'normalized-load'.
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.
Fixes <https://bugs.gnu.org/33378>.
* guix/scripts/offload.scm (node-free-disk-space): New procedure.
(%minimum-disk-space): New variable.
(choose-build-machine): Call 'node-free-disk-space' and take it into
account in addition to LOAD.
(check-machine-status): Display the free disk space.
* guix/scripts/offload.scm (machine-load): Remove.
(node-load, normalized-load): New procedures.
(choose-build-machine): Call 'open-ssh-session' and 'make-node' from
here; pass the node to 'node-load'.
(check-machine-status): Use 'node-load' instead of 'machine-load'. Call
'disconnect!' on SESSION.
