Before commit 54fa0cfe4e, the `redshift`
service was run with the environment variable `DISPLAY` set to `:0`.
Commit 54fa0cfe4e changed this to
instead use the value of the `services.xserver.display` configuration
option in the value of the `DISPLAY` variable. In so doing, no default
value was provided for the case where `services.xserver.display` is
`null`.
While the default value of `services.xserver.display` is `0`, use of
which by the `redshift` module would result in `DISPLAY` again being
set to `:0`, `services.xserver.display` may also be `null`, to which
value it is set by, e.g., the `lightdm` module.
In the case that `services.xserver.display` is `null`, with the change
made in commit 54fa0cfe4e, the `DISPLAY`
variable in the environment of the `redshift` service would be set to
`:` (a single colon), which, according to my personal experience,
would result in —
- the `redshift` service failing to start; and
- systemd repeatedly attempting to restart the `redshift` service,
looping indefinitely, while the hapless `redshift` spews error
messages into the journal.
It can be observed that the malformed value of `DISPLAY` is likely at
fault for this issue by executing the following commands in an
ordinary shell, with a suitable `redshift` executable, and the X11
display not already tinted:
- `redshift -O 2500` — This command should reduce the color
temperature of the display (making it more reddish).
- `DISPLAY=':' redshift -O 6500` — This command should raise the
color temperature back up, were it not for the `DISPLAY`
environment variable being set to `:` for it, which should cause
it to, instead, fail with several error messages.
This commit attempts to fix this issue by having the `DISPLAY`
environment variable for the `redshift` service default to its old
value of `:0` in the case that `services.xserver.display` is `null`.
I have tested this solution on NixOS, albeit without the benefit of a
system with multiple displays.
gdnc is a user process and can't be made into a NixOS module very
easily. It can still be put in the user's login script. According to the
GNUstep documentation it will be started as soon as it is needed.
- Agent now takes a full URL to the Go.CD server
- Instruct the agent to attempt restart every 30s upon failure
- Test's Accept header did not match the server's expectation
- Replace the tests' complex Awk matches with calls to `jq`
Update gocd-agent package version to 16.6.0-3590 including new sha. Modify heapSize
and maxMemory mkOption to accurately reflect their intended purpose of configuring
initial java heap sizes.
From @fpletz: Keep poolConfigs option for backwards-compatibility.
The original commit 6b3f5b5a42 was previously
reverted by c7860cae1a but the issues were
resolved.
The varnish tools (varnishstat, varnishlog, ...) tried to load the VSM
file from a spurious var directory in the Nix store. Fix the default so
the tools "just work" when also keeping services.varnish.stateDir at the
default.
Notes:
- The tools use $localstatedir/$HOSTNAME so I've adapted the default for
stateDir as well to contain hostName.
- Added postStop action to remove the localstatedir. There is no point
in keeping it around when varnish does not run, as it regenerates it
on startup anyway.
Fixes#7495
The name gitlab-runner clashes with a component of Gitlab CI with the
same name and only confuses people. It's now called gitlab-bundle and
a convenience-script gitlab-rake for easier invocation of rake tasks
was added. This was the primary use case of gitlab-runner.
The module will configure a Cassandra server with common options being
tweakable. Included is also a test which will spin up 3 nodes and
verify that the cluster can be formed, broken, and repaired.
In light of Emacs packaging improvements such as those mentioned
in #11503, and with the addition of a systemd service (#15807
and #16356), and considering that the wiki page is completely
out of date (#13217), it seems that some documentation is in order.
Adds a new chain in the raw table for reverse path filtering and optional
logging. A rule to allow serving DHCPv4 was also added as it is commonly
needed and poses no security risk even when no DHCPv4 server is running.
Fixes#10101.
Instead of one package `extra-cmake-modules`, there is now `ecm` and
`ecmNoHooks`. The latter is used when one does not want to incur a Qt 5
dependency; it is also available as a top-level package
`extra-cmake-modules`.
Revert httpConfig its old behaviour and make it mutually exclusive to
the new structured configuration. Adds appendHttpConfig to have the
ability to write custom config in the generated http block.
This reverts commit 6b3f5b5a42 because it
introduced a non-backwards compatible change in the phpfpm interface,
without really needing to. The new interface, if needed, can be re-added
alongside the old interface.
Commit 98e419c0e2 ("tt-rss service: init at 16.3")
depends on the new interface, so this commit updates the tt-rss service
to work with the old services.phpfpm.poolConfigs interface.
Update gocd-server package version to 16.6.0-3590 including new sha. Modify heapSize
and maxMemory mkOption to accurately reflect their intended purpose of configuring
initial java heap sizes.
Note: the option to configure the watchdog timeout seems to be gone
in the 2.3 series of Logstash. It complains about an unknown option
and it is not in the source anymore. I am thus removing this
configuration option to adjust the service to these changes, too.
GoCD is an open source continuous delivery server specializing in advanced workflow
modeling and visualization. Update maintainers list to include swarren83. Update
module list to include gocd agent and server module. Update packages list to include
gocd agent and server package. Update version, revision and checksum for GoCD
release 16.5.0.
KDM and LightDM (at least with autologin) call the xsession-script with
two arguments: the first is the path of the xsession script itself,
while the second one are the actual arguments. The line to re-exec the
script under systemd-cat only forwarded a single argument, therefore
breaking LightDM and KDM login. This commit fixes the issue by always
forwarding all the arguments.
We need to pass certain environment variables through the wrapper, but I
don't know how to do that yet. The setuid-root feature serves only to
hide kdeinit from the OOM killer, so this is not critical.
