- Fully get rid of `parseKeyValues` and use systemctl features for that
- Add some regex modifiers recommended by perlcritic
- Get rid of a postfix if
- Sort units when showing their status
- Clean the logic for showing what failed from `elif` to `next`
- Switch from `state` to `substate` for `auto-restart` because that's
actually where the value is stored
- Show status of units with one single systemctl call and get rid of
COLUMNS in favor of --full
- Add a test for failing units
This removes `/run/nixos/activation-reload-list` (which we will need in
the future when reworking the reload logic) and makes
`/run/nixos/activation-restart-list` honor `restartIfChanged` and
`reloadIfChanged`. This way activation scripts don't have to bother with
choosing between reloading and restarting.
This reverts commit 57961d2b838cc31fa4ce89641b6a8db544a8471a, reversing
changes made to b04f913afce4419f6b777fd64ac52315dbef3aaf.
(I.e. this reverts PR #141192.)
While well-intended, this change does unfortunately introduce very
serious regressions that are especially disruptive/noticeable on desktop
systems (e.g. users of Sway will loose their graphical session when
running "nixos-rebuild switch").
Therefore, this change has to be reverted ASAP instead of trying to fix
it in "production".
Note: An updated version should be extensively discussed, reviewed, and
tested before re-landing this change as an earlier version also had to
be reverted for the exact same issues [0].
Fix: #146727
[0]: https://github.com/NixOS/nixpkgs/pull/73871#issuecomment-559783752
This commit changes a lot more that you'd expect but it also adds a lot
of new testing code so nothing breaks in the future. The main change is
that sockets are now restarted when they change. The main reason for
the large amount of changes is the ability of activation scripts to
restart/reload units. This also works for socket-activated units now,
and honors reloadIfChanged and restartIfChanged. The two changes don't
really work without each other so they are done in the one large commit.
The test should show what works now and ensure it will continue to do so
in the future.
The `| tee` invocation always masked the return value of the
switch-to-configuration test.
```
~ $ false | tee && echo "oh no"
oh no
```
The added wrapper script will still output everything to stderr, while
passing failures to the test harness.
Fixes#28443
Fixed few invocations to `systemctl` to have an absolute path. Additionally add
LOCALE_ARCHIVE so that perl stops spewing warning messages.
