Finally, this is where we declaratively set up our organisations and
users/groups, which looks like this in the system configuration:
services.taskserver.organisations.NixOS.users = [ "alice" "bob" ];
This automatically sets up "alice" and "bob" for the "NixOS"
organisation, generates the required client keys and signs it via the
CA.
However, we still need to use nixos-taskdctl export-user in order to
import these certificates on the client.

It's a helper for NixOS systems to make it easier to handle CA
certificate signing, similar to what taskd provides but comes preseeded
with the values from the system configuration.
The tool is very limited at the moment and only allows to *add*
organisations, users and groups. Deletion and suspension however is much
simpler to implement, because we don't need to handle certificate
signing.
Another limitation is that we don't take into account whether
certificates and keys are already set in the system configuration and if
they're set it will fail spectacularly.
For passing the commands to the taskd command, we're using a small C
program which does setuid() and setgid() to the Taskserver user and
group, because runuser(1) needs PAM (quite pointless if you're already
root) and su(1) doesn't allow for setting the group and setgid()s to the
default group of the user, so it even doesn't work in conjunction with
sg(1).
In summary, we now have a shiny nixos-taskdctl command, which lets us do
things like:
nixos-taskdctl add-org NixOS
nixos-taskdctl add-user NixOS alice
nixos-taskdctl export-user NixOS alice
The last command writes a series of shell commands to stdout, which then
can be imported on the client by piping it into a shell as well as doing
it for example via SSH:
ssh root@server nixos-taskdctl export-user NixOS alice | sh
Of course, in terms of security we need to improve this even further so
that we generate the private key on the client and just send a CSR to
the server so that we don't need to push any secrets over the wire.

We want to declaratively specify users and organisations, so let's add
another module option "organisations", which allows us to specify users,
groups and of course organisations.
The implementation of this is not yet done and this is just to feed the
boilerplate.

Using just the host for the common name *and* for listening on the port
is quite a bad idea if you want to listen on something like :: or an
internal IP address which is proxied/tunneled to the outside.
Hence this separates host and fqdn.

The server starts up without that option anyway, but it complains about
its value not being set. As we probably want to have access to that
configuration value anyway, let's expose this via the NixOS module as
well.

Now the service starts up if only the services.taskserver.enable option
is set to true.
We now also have three systemd services (started in this order):
* taskserver-init: For creating the necessary data directory and also
includes a refecence to the configuration file in
the Nix store.
* taskserver-ca: Only enabled if none of the server.key, server.cert,
server.crl and caCert options are set, so we can
allow for certificates that are issued by another
CA.
This service creates a new CA key+certificate and a
server key+certificate and signs the latter using
the CA key.
The permissions of these keys/certs are set quite
strictly to allow only the root user to sign
certificates.
* taskserver: The main Taskserver service which just starts taskd.
We now also log to stdout and thus to the journal.
Of course, there are still a few problems left to solve, for instance:
* The CA currently only signs the server certificates, so it's
only usable for clients if the server doesn't validate client certs
(which is kinda pointless).
* Using "taskd <command>" is currently still a bit awkward to use, so
we need to properly wrap it in environment.systemPackages to set the
dataDir by default.
* There are still a few configuration options left to include, for
example the "trust" option.
* We might want to introduce an extraConfig option.
* It might be useful to allow for declarative configuration of
organisations and users, especially when it comes to creating client
certificates.
* The right signal has to be sent for the taskserver service to reload
properly.
* Currently the CA and server certificates are created using
server.host as the common name and doesn't set additional certificate
information. This could be improved by adding options that explicitly
set that information.
As for the config file, we might need to patch taskd to allow for
setting not only --data but also a --cfgfile, which then omits the
${dataDir}/config file. We can still use the "include" directive from
the file specified using --cfgfile in order to chainload
${dataDir}/config.

The descriptions for the options previously seem to be from the
taskdrc(5) manual page. So in cases where they didn't make sense for us
I changed the wording a bit (for example for client.deny we don't have a
"comma-separated list".
Also, I've reordered things a bit for consistency (type, default,
example and then description) and add missing types, examples and
docbook tags.
Options that are not used by default now have a null value, so that we
can generate a configuration file out of all the options defined for the
module.
The dataDir default value is now /var/lib/taskserver, because it doesn't
make sense to put just yet another empty subdirectory in it and "data"
doesn't quite make sense anyway, because it also contains the
configuration file as well.

We're aiming for a proper integration into systemd/journald, so we
really don't want zillions of separate log files flying around in our
system.
Same as with the pidFile. The latter is only needed for taskdctl, which
is a SysV-style initscript and all of its functionality plus a lot more
is handled by systemd already.

The service doesn't start with the "taskd" user being present, so we
really should add it. And while at it, it really makes sense to add a
default group as well.
I'm using a check for the user/group name as well, to allow the
taskserver to be run as an existing user.

- Enforce that an option declaration has a "defaultText" if and only if the
type of the option derives from "package", "packageSet" or "nixpkgsConfig"

Updates gitlab to the current stable version and fixes a lot of features that
were broken, at least with the current version and our configuration.
Quite a lot of sweat and tears has gone into testing nearly all features and
reading/patching the Gitlab source as we're about to deploy gitlab for our
whole company.
Things to note:
* The gitlab config is now written as a nix attribute set and will be
converted to JSON. Gitlab uses YAML but JSON is a subset of YAML.
The `extraConfig` opition is also an attribute set that will be merged
with the default config. This way *all* Gitlab options are supported.
* Some paths like uploads and configs are hardcoded in rails (at least
after my study of the Gitlab source). This is why they are linked from
the Gitlab root to /run/gitlab and then linked to the configurable
`statePath`.
* Backup & restore should work out of the box from another Gitlab instance.
* gitlab-git-http-server has been replaced by gitlab-workhorse upstream.
Push & pull over HTTPS works perfectly. Communication to gitlab is done
over unix sockets. An HTTP server is required to proxy requests to
gitlab-workhorse over another unix socket at
`/run/gitlab/gitlab-workhorse.socket`.
* The user & group running gitlab are now configurable. These can even be
changed for live instances.
* The initial email address & password of the root user can be configured.
Fixes#8598.
We don't want to build all those things along with the manual, so that's
what the defaultText attribute is for.
Unfortunately a few of them were missing, so let's add them.

This reverts most of 89e983786a, as those references are sanitized now.
Fixes#10039, at least most of it.
The `sane` case wasn't fixed, as it calls a *function* in pkgs to get
the default value.
This is an improved version of original #12357.
For the purpose of generating docs, evaluate options with each derivation
in `pkgs` (recursively) replaced by a fake with path "\${pkgs.attribute.path}".
It isn't perfect, but it seems to cover a vast majority of use cases.
Caveat: even if the package is reached by a different means,
the path above will be shown and not e.g. `${config.services.foo.package}`.
As before, defaults created by `mkDefault` aren't displayed,
but documentation shouldn't (mostly) be a reason to use that anymore.
Note: t wouldn't be enough to just use `lib.mapAttrsRecursive`,
because derivations are also (special) attribute sets.

This module implements a way to start one or more bepasty servers.
It supports configuring the listen address of gunicorn and how bepasty
behaves internally.
Configuring multiple bepasty servers provides a way to serve pastes externally
without authentication and provide creating,listing,deleting pastes interally.
nginx can be used to provide access via hostname + listen address.
`configuration.nix`:
services.bepasty = {
enable = true;
servers = {
internal = {
defaultPermissions = "admin,list,create,read,delete";
secretKey = "secret";
bind = "127.0.0.1:8000";
};
external = {
defaultPermissions = "read";
bind = "127.0.0.1:8001";
secretKey = "another-secret";
};
};
};
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
Also related to NixOS/nixops#350, because while switching to the new
configuration, depending on /nix/store also propagates to the mount
points for /nix/.ro-store and /nix/.rw-store and we don't get an error
while trying to unmount them (because nix-daemon needs to be stopped for
unmounting these paths).
While Nix does have the option to set a different store path, I've found
only hardcoded references in nix-daemon.nix, so I'm using a hardcoded
reference here as well, because after all customizing the store path
will probably only make sense on non-NixOS systems.

Synergy seems to get more and more unstable in recent versions, so we
might want to debug this properly. However, it makes sense to restart
the service nevertheless, because synergy is about keyboard and mouse

This reverts commit ab6c8643d4. Issue
https://github.com/NixOS/nix/issues/609 has been resolved, the new Nix
version is available after 86eaeb4c0a, and
using nix-collect-garbage has the advantage that the '-d' flag is
available, which nix-store doesn't have.
These are just trusted-users and allowed-users in nix.conf. It's
useful to have options for them so that different modules can specify
trusted/allowed users.
JVMs exit with exit code 128+signal when receiving a (terminating)
signal. This means graceful termination of a JVM will result in 143, so
add that to `SuccessExitStatus` in systemd service unit.
- Usage of docker containerizer is currently hardcoded, this PR makes it
optional. Default is to enable it if docker is enabled.
- Make IP address to listen on part of service configuration.
Added support for managing Plex plugins via Nix. This is done via an
"extraPlugins" configuration option which takes a list of paths to
plugin bundles, which are then symlinked into Plex's plugin directory
when the service is started.
This allows for module arguments to be handled modularly, in particular
allowing the nixpkgs module to handle the nixpkgs import internally.
This creates the __internal option namespace, which should only be added
to by the module system itself.
Typical use:
nix.requireSignedBinaryCaches = true;
nix.binaryCachePublicKeys = [ "hydra.nixos.org-1:CNHJZBh9K4tP3EKF6FkkgeVYsS3ohTl+oS0Qa8bezVs=" ];
(The public key of cache.nixos.org is included by default.)
Note that this requires Nix 1.9 and that most of cache.nixos.org
hasn't been signed yet.

It turns out that installing therubytracer, with dependency on old v8, even
when using source libv8 version is problematic.
(see
http://stackoverflow.com/questions/21666379/problems-installing-gitlab-on-odroid-v8-lib-not-available).
But wait, rails does not even need therubytracer, just any kind of javascript
server side execution framework like nodejs. Well just use that, as also
suggested from different internet sources (look link above), it works just
fine.
I had to make several adjustments to make it work with nixos:
* Replace relative config file lookups with ENV variable.
* Modify gitlab-shell to not clear then environment when running
pre-receive.
* Modify gitlab-shell to write some environment variables into
the .authorized_keys file to make sure gitlab-shell reads the
correct config file.
* Log unicorn output to syslog.
I tried various ways of adding a syslog package but the bundler would
not pick them up. Please fix in a better way if possible.
* Gitlab-runner program wrapper.
This is useful to run e.g. backups etc. with the correct
environment set up.
Following the discussion NixOS#5021:
- obsolete the nix.proxy option
- add the networking.proxy option
- open a default no_proxy environment variable
- add a rsync option
- Manual tests ok.
- Automatic tests ok.
Amended by lethalman to simplify the option descriptions.
This led to the container test failing, which made no sense
whatsoever, until I realized nix-daemon.socket creates the socket
directory as a side effect, which systemd-nspawn then bind-mounts.

If you define a unit, and either systemd or a package in
systemd.packages already provides that unit, then we now generate a
file /etc/systemd/system/<unit>.d/overrides.conf. This makes it
possible to use upstream units, while allowing them to be customised
from the NixOS configuration. For instance, the module nix-daemon.nix
now uses the units provided by the Nix package. And all unit
definitions that duplicated upstream systemd units are finally gone.
This makes the baseUnit option unnecessary, so I've removed it.
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.

Previously changing the value of certain options in configuration.nix
would cause the manual to be regenerated, because some option defaults
depend on the configuration. This is undesirable because rebuilding
the manual is kind of slow. So now the manual reflects an empty
configuration.
The downside is that this requires another call to fixMergeModules,
which adds about 14% to evaluation time. Probably worth it.
