See http://debbugs.gnu.org/cgi/bugreport.cgi?bug=37318.
* gnu/services/networking.scm (openntpd-configuration->string): New procedure,
extracted from top of the `openntpd-shepherd-service' to make it testable.
(openntpd-shepherd-service): Adapt following the move of the code to the above
procedure.
* tests/networking.scm: Add a test for the `openntpd-configuration->string'
procedure.
The error printed by nttpd was "constraint: failed to load constraint ca" when
libressl tried loading the file /etc/ssl/cert.pem. The problem was
investigated as part of fixing issue 37318 (see:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=37318).
* gnu/packages/ntp.scm (openntpd)[configure-flags]: Use the '--with-cacert'
flag to specify the location of the certificate authority file of libressl.
* gnu/services/networking.scm (ntp-server-types): New enum.
(<ntp-server>): New record type.
(ntp-server->string): New procedure.
(%ntp-servers): Define in terms of <htp-server> records. Use the first
entrypoint server as a pool instead of a list of static servers. This is more
resilient since a new server of the pool can be interrogated on every
request. Add the 'iburst' options.
(ntp-configuration-servers): Define a custom accessor that warns but honors
the now deprecated server format.
(<ntp-configuration>): Use it.
(%openntpd-servers): New variable,
(<openntpd-configuration>): Use it, as a pool ('servers' field) instead of a
regular server.
* tests/networking.scm: New file.
* Makefile.am (SCM_TESTS): Register it.
* doc/guix.texi: Update documentation.
Otherwise the following messages would be printed by ntpd:
Sep 2 05:18:21 localhost ntpd[15849]: restrict default: KOD does nothing without LIMITE.
Sep 2 05:18:21 localhost ntpd[15849]: restrict ::: KOD does nothing without LIMITED.
Debian uses the same set of "restrict" keywords (see:
https://sources.debian.org/src/ntp/1:4.2.8p13+dfsg-2/debian/ntp.conf).
* gnu/services/networking.scm (ntp-shepherd-service): Add the 'limited'
keyword to both the IPv4 and IPv6 'restrict' directives.
This is documented as best practice in `man ntpd', and is required to allow
the date to be set correctly when traveling (without having to manually update
the hardware clock in the BIOS/UEFI).
* gnu/services/networking.scm (<ntp-server>)[allow-large-adjustment?]: Set the
default value to #t.
* doc/guix.texi (Networking Services): Update documentation.
This is a followup to 81c3dc3224.
Since that commit, when /releases returned an empty JSON array, we would
not fall back to /tags because of the incorrect match.
* guix/import/github.scm (fetch-releases-or-tags): Match the empty
vector instead of the empty list.
The daemon had a mechanism that allows it to handle a list of
substituters and try them sequentially; this removes it.
* nix/scripts/substitute.in: Remove.
* nix/local.mk (nodist_pkglibexec_SCRIPTS): Remove.
* config-daemon.ac: Don't output 'nix/scripts/substitute'.
* nix/libstore/build.cc (SubstitutionGoal)[subs, sub, hasSubstitute]:
Remove.
[tryNext]: Make private.
(SubstitutionGoal::SubstitutionGoal, SubstitutionGoal::init): Remove now
unneeded initializers.
(SubstitutionGoal::tryNext): Adjust to assume a single substituter: call
'amDone' upfront when we couldn't find substitutes.
(SubstitutionGoal::tryToRun): Adjust to run 'guix substitute' via
'settings.guixProgram'.
(SubstitutionGoal::finished): Call 'amDone(ecFailed)' upon failure
instead of setting 'state' to 'tryNext'.
* nix/libstore/globals.hh (Settings)[substituters]: Remove.
* nix/libstore/local-store.cc (LocalStore::~LocalStore): Adjust to
handle a single substituter.
(LocalStore::startSubstituter): Remove 'path' parameter. Adjust to
invoke 'settings.guixProgram'. Don't refer to 'run.program', which no
longer exists.
(LocalStore::querySubstitutablePaths): Adjust for 'runningSubstituters'
being a singleton instead of a list.
(LocalStore::querySubstitutablePathInfos): Likewise, and remove
'substituter' parameter.
* nix/libstore/local-store.hh (RunningSubstituter)[program]: Remove.
(LocalStore)[runningSubstituters]: Remove.
[runningSubstituter]: New field.
[querySubstitutablePathInfos]: Remove 'substituter' parameter.
[startSubstituter]: Remove 'substituter' parameter.
* nix/nix-daemon/guix-daemon.cc (main): Remove references to
'settings.substituters'.
* nix/nix-daemon/nix-daemon.cc (performOp): Ignore the user's
"build-use-substitutes" value when 'settings.useSubstitutes' is false.
* gnu/packages/python-xyz (python-debian): Update to 0.1.36.
[source]: Switch to using git-fetch.
[arguments]: Add phase to delete tests depending on tools not yet present in
guix.
[propagated-inputs]: Add python-chardet.
