I was under the impression that setting `services.redis.servers.<name>.save = []` would disable RDB persistence as no schedule would mean no persistence. However since the code did not handle this case specially it actually results in no `save` setting being written and the internal Redis default is used.
This patch handles the empty case to disable RDB persistence.
Disabling RDB persistence is useful in a number of scenarios:
1. Using Redis in a pure-cache mode where persistence is not desired.
2. When using the (generally superior) AOF persistence mode this file is never read so there is little point to writing it.
3. When saving is handled manually
For more information see https://redis.io/docs/manual/persistence/
This is a breaking change as the user may have been relying on `[]` using Redis defaults. However I believe that updating the behaviour for the next release is beneficial as IMHO it is less surprising and does what the user would expect. I have added release notes to warn about this change.
* nixos/vault: add option to start in dev mode.
This is not only useful for nixos tests i.e. when testing vault agent
setups but also when playing around with vault in local setups. In our
tests we can now make use of this option to test more vault features.
i.e. adding this feature has uncovered the need for a `StateDirectory`.
* Update nixos/modules/services/security/vault.nix

Simon passed away in December 2021.
Simon, it was a pleasure to work with you, to learn things together
and to share good times. It ended too soon. You will be missed.
* Update attribute names in code examples (* -> settings.*).
* Use `nix-shell -p` rather than `nix run` because the example won't
work with the current default Nix.
* Update config values for `element-web`.
* Fix link to `element-web` security considerations.
* Make the synapse expression even smaller and use callout-lists to
explain the code.
* Document how to correctly deploy the shared registration secret.

Potential use cases for disabling `useDefaultFilesystems` include:
- Testing with uncommon filesystem layouts
- Testing scenarios where swapping occurs
- Testing with LUKS-encrypted disks
Closes#177963
we can't add 'nixpkgs.curl.tests' to hydra jobs due to 'tests' (and 'passthru') being stripped
TODO: add a function in lib-release.nix to get derivations and add `.x86_64-linux` to them
then we can just point release files to nixpkgs.tests.packageTestsForChannelBlockers instead of
nixpkgs.tests.packageTestsForChannelBlockers.curl.withCheck
Running `nixos/tests/keepassxc.nix` shows:
```
machine # [ 18.705390] xsession[985]: /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession: line 13: nn: command not found
```
This garbled bash script runs without `set -o errexit` and thus skips
"\n\n" as invalid command:
```
$ cat -n /nix/store/2g2jx5c6x3p152wbiijr0rmky7byqivc-xsession
...
\n\n
if [ -e $HOME/.background-image ]; then
/nix/store/wq1d1ph8wj4alpx78akvpbd0a0m9qkd1-feh-3.8/bin/feh --bg-scale $HOME/.background-image
fi
...
```
KeePassXC uses it through
`nixos/modules/services/x11/display-managers/default.nix`:
```
...
# Script responsible for starting the window manager and the desktop manager.
xsession = dm: wm: pkgs.writeScript "xsession" ''
#! ${pkgs.bash}/bin/bash
# Legacy session script used to construct .desktop files from
# `services.xserver.displayManager.session` entries. Called from
# `sessionWrapper`.
# Start the window manager.
${wm.start}
# Start the desktop manager.
${dm.start}
...
'';
...
```
The bogus line was introduced in PR #160752:
```
commit 0bc0dc8090
Author: Shaw Vrana <shaw@vranix.com>
Date: Fri Feb 18 11:27:42 2022 -0800
desktop manager script: start properly
Adds a missing line feed when X is enabled to the start script name
and the appended if check. Resolves#160735
```
I have not tried to reproduce the original issue and thus don't know
why "\n\n" apparently gets interpreted fine in one place but remains
literal the `xsession` case.
However, using a literal newline must be valid for all cases and
certainly fixes the warning seen in KeePassXC tests.
Furthermore, starting the nix string (`''`) with a newline as usual also
fixes its overall indentation.
This patch follows an upstream commit[1].
Before this patch, if acme module is used, caddy will still use an old
cert even a new one is available. The cause is that without --force
flag, caddy will not reload an unchanged config.
Refer to that commit[1] message for more information.

Seems silly to install this for use with the local server, but to not
configure it to use the local server. Otherwise, out of the box we
just get an error about no server being configured.
By writing the unchecked outputs before checking them, they will
be written to a store path, which appears in the log, and which
sticks around even if the build fails. Eventually it is GCed, but
until then, you can open the file.
If you run it in a terminal+editor combination like VSCode, the
failure location is just one Ctrl+click away.
The `nixos-rebuild` tool calls `get-version-suffix` to figure out the
git revision of the nixpkgs directory if there is a .git.
https://nvd.nist.gov/vuln/detail/CVE-2022-24765 made git throw an
error if the .git search logic is not turned off and a user
tries to access a `.git` directory they don’t own (otherwise a
different user could trick them into setting arbitrary git config).
So from now on we should always explicitely set `--git-dir`, which
turns this search logic (and thus the security check) off.
I have read the full diff[0] between the previous owner and the new
maintained fork that I'm switching to, and could not find any suspicious
code. The new fork includes fixes that are otherwise crashing as of
Python 3.10.
This commit also fixes the PYTHONPATH which prevents the client from
starting.
This commit also adds a test that the client can successfully query the
server, testing the two components at once.

It was never meant to be used for anything other than testing
and setting it globally can cause weird loops in GTK-based portals,
where the portal will end up waiting for itself until it times out.
https://github.com/NixOS/nixpkgs/issues/135898
Or it can mess up fonts:

Having the option in NixOS makes it look like it is okay or even
desirable to enable, when in fact it is a hack that can subtly break apps.
Some apps allow opting into using portal-based APIs, e.g. for Firefox,
you can set `widget.use-xdg-desktop-portal.file-picker` to `1` in about:config.
Otherwise, you can set the `GTK_USE_PORTAL` environment variable to 1
for individual apps.
People who really want it and aware of the downsides can just set
`environment.sessionVariables.GTK_USE_PORTAL = "1";` NixOS option
directly to set the environment variable globally.
dhclient is no longer built by default in the dhcp package, so this
test has been broken since that change was made. To fix, switch to
dhcpcd. dhcpcd insists on writing into /var/run, so we need to ensure
that exists.
Fixes: a2c379d4b6 ("dhcp: make client and relay component optional")
This used to be StandardOutput=syslog, which was removed because
syslog is deprecated, but that caused the test to fail. So bring it
back, but set it to the non-deprecated "journal" value instead (which
is what systemd interprets "syslog" as now anyway).
Fixes: 962e15aebc ("nixos: remove StandardOutput=syslog, StandardError=syslog lines")
Otherwise, since the update to Virtualbox 6.1.22, the test would fail
due to the shared directory not existing.
Fixes: ba0da8a076 ("virtualbox: 6.1.18 -> 6.1.22")
Nested KVM has been enabled by default on Linux on Intel for a long
time now, and since Virtualbox 6.1.0, the test won't run without it
because Virtualbox now only supports running hardware-accelerated VMs.
Additionally, this means we can 64-bit guests by default. The 32-bit
guest additions don't currently build, so this is important to have
the tests work with the default options.
- Add a module for the thunar file manager, which depends on the xfconf dbus service, and also has a dbus service and a systemd unit.
- Renames the option services.xserver.desktopManager.xfce.thunarPlugins to programs.thunar.plugins.
Riak have been updated a lot since the version 2.2 (now 3.0.10) but
has seen no updated to the package. This is at this point
a problem forcing us to maintain old versions of erlang.
We would be happy to re accept a newer version of Riak if someone want
to spend the time to set it up.
The original implementation did a simple string-comparison against the
output of `ip route`. This is problematic because
* if the details in the string-output change, the test breaks. This is
less likely with JSON because the relevant values (i.e. destination,
interface etc) aren't supposed to be changed.
* this is causing issues with formatters[1][2].

With multiple specialization changes this isn't very helpful anymore,
but no biggie since we check the log for errors anyway and the log is
not too verbose anyway.
Use `networking.resolvconf.package` to allow DNS entries to be set using
the system-wide resolver implementation instead of hardcoding systemd or
openresolv.
Extend the tests by adding DNS entries and making one of the peers use
systemd-networkd (hence systemd-resolved).
Also add a few `networkd`-specific settings.
The substr solution assumed a newline to be present.
The new solution will not remove the newline if it goes missing in the future.
Apparently this is idiomatic perl.
Thanks pennae for the suggestion!
According to https://grafana.com/docs/agent/latest/upgrade-guide/#v0240,
this has been deprecated/moved to -server.http.address and
-server.grpc.address (accepting ip and port) config options in v0.24.0,
and already listens on localhost and not port 80 by default.
According to https://github.com/grafana/agent/pull/1540, -prometheus.*
flages were deprecated in 0.19.0 in favor of the -metrics.*
counterparts. Same applies to `loki` being renamed to `logs`.
I'm not sure if the config file format is still supported (it could be),
but we shouldn't use deprecated configs.
