Right now it's not at all obvious that one can override this option
using `services.logind.extraConfig`; we might as well add an option
for `killUserProcesses` directly so it's clear and documented.
They consistently fail since openjdk bump with some out-of-space errors.
That's not a problem by itself, but each test instance ties a build slot
for many hours and consequently they also delay channels as those wait
for all builds to finish.
Feel free to re-enable when fixed, of course.
The test now runs wayland, which means we can no longer use X11 style testing.
Instead we get gnome shell to execute javascript through its dbus interface.
Since 83b27f60ce, the tests were moved
into all-tests.nix and some of the tooling has changed so that
subattributes of test expressions are now recursively evaluated until a
derivation with a .test attribute has been found.
Unfortunately this isn't the case for all of the tests and the
runInMachine doesn't use the makeTest function other tests are using but
instead uses runInMachine, which doesn't generate a .test attribute.
Whener a .test attribute wasn't found by the new handleTest function, it
recurses down again until there is no value left that is an attribute
set and subsequently returns its unchanged value. This however has the
drawback that instead of getting different attributes for each
architecture we only get the last architecture in the supportedSystems
list.
In the case of the release.nix, the last architecture in
supportedSystems is "aarch64-linux", so the runInMachine test is always
built on that architecture.
In order to work around this, I changed runInMachine to emit a .test
attribute so that it looks to handleTest like it was a test created via
makeTest.

Docker images used to be, essentially, a linked list of layers. Each
layer would have a tarball and a json document pointing to its parent,
and the image pointed to the top layer:
imageA ----> layerA
|
v
layerB
|
v
layerC
The current image spec changed this format to where the Image defined
the order and set of layers:
imageA ---> layerA
|--> layerB
`--> layerC
For backwards compatibility, docker produces images which follow both
specs: layers point to parents, and images also point to the entire
list:
imageA ---> layerA
| |
| v
|--> layerB
| |
| v
`--> layerC
This is nice for tooling which supported the older version and never
updated to support the newer format.
Our `buildImage` code only supported the old version, so in order for
`buildImage` to properly generate an image based on another image
with `fromImage`, the parent image's layers must fully support the old
mechanism.
This is not a problem in general, but is a problem with
`buildLayeredImage`.
`buildLayeredImage` creates images with newer image spec, because
individual store paths don't have a guaranteed parent layer. Including
a specific parent ID in the layer's json makes the output less likely
to cache hit when published or pulled.
This means until now, `buildLayeredImage` could not be the input to
`buildImage`.
The changes in this PR change `buildImage` to only use the layer's
manifest when locating parent IDs. This does break buildImage on
extremely old Docker images, though I do wonder how many of these
exist.

Instead of setting User/Group only when DynamicUser is disabled, the
previous version of the code set it only when it was enabled. This
caused services with DynamicUser enabled to actually run as nobody, and
services without DynamicUser enabled to run as root.
Regression from fbb7e0c82f.
GitLab 11.5.1 dropped the dependency to posix_spawn, which is broken on
32bit. (See https://gitlab.com/gitlab-org/gitlab-ce/issues/53525)
The only part missing is decreasing virtualisation.memorySize to
something that a 32 bit qemu still executes.
The maximum seems to be 2047, and tests passed with that value for me.
This cleans up the CockroachDB expression, with a few suggestions from
@aszlig.
However, it brought up the note of using systemd's StateDirectory=
directive, which is a nice feature for managing long-term data files,
especially for UID/GID assigned services. However, it can only manage
directories under /var/lib (for global services), so it has to introduce
a special path to make use of it at all in the case someone wants a path
at a different root.
While the dataDir directive at the NixOS level is _occasionally_ useful,
I've gone ahead and removed it for now, as this expression is so new,
and it makes the expression cleaner, while other kinks can be worked out
and people can test drive it.
CockroachDB's dataDir directive, instead, has been replaced with
systemd's StateDirectory management to place the data under
/var/lib/cockroachdb for all uses.
There's an included RequiresMountsFor= clause like usual though, so if
people want dependencies for any kind of mounted device at boot
time/before database startup, it's easy to specify using their own
mount/filesystems clause.
This can also be reverted if necessary, but, we can see if anyone ever
actually wants that later on before doing it -- it's a backwards
compatible change, anyway.
