When the user specifies the networking.nameservers setting in the
configuration file, it must take precedence over automatically
derived settings.
The culprit was services.bind that made the resolver set to
127.0.0.1 and ignore the nameserver setting.
This patch adds a flag to services.bind to override the nameserver
to localhost. It defaults to true. Setting this to false prevents the
service.bind and dnsmasq.resolveLocalQueries settings from
overriding the users' settings.
Also, when the user specifies a domain to search, it must be set in
the resolver configuration, even if the user does not specify any
nameservers.
(cherry picked from commit 670b4e29adc16e0a29aa5b4c126703dcca56aeb6)
This commit was accidentally merged to 17.09 but was intended for
master. This is the cherry-pick to master.
Previously services depending on network-online.target would wait until
dhcpcd times out if it was enabled and a static network address
configuration was used. Setting the default gateway statically is enough
for the networking to be considered online.
This also adjusts the relevant networking tests to wait for
network-online.target instead of just network.target.
If neither database.password or database.passwordFile were provided,
it would try and fail to coerce null to a string.
This fixes the situation where there is no password for the database.
Resolves#27950
This option got introduced in 7904499542
and it didn't check whether mailUser and mailGroup are null, which they
are by default.
Now we're only creating the user if createMailUser is set in conjunction
with mailUser and the group if mailGroup is set as well.
I've added a NixOS VM test so that we can verify whether dovecot works
without any additional options set, so it serves as a regression test
for issue #29466 and other issues that might come up with future changes
to the Dovecot service.

the systemd.unit(5) discussion of wantedBy and requiredBy is in the
[Install] section, and thus focused on stateful 'systemctl enable'.
so, clarify that in NixOS, wantedBy & requiredBy are still what most
users want, and not to be confused with enabled.
Arguably, breaking linux-latest should not block a release. Also, booting
the kernel + basic sanity checking is implicitly exercised by every other
vm test.
For various reasons, big Nix attrsets look ugly in the generated manual
page[1]. Use literalExample to fix it.
[1] Quotes around attribute names are lost, newlines inside multi-line
strings are shown as '\n' and attrs written on multiple lines are joined
into one.
Quoting from @FRidh:
Note overridePythonAttrs exists since 17.09. It overrides the call to
buildPythonPackage.
While it's not strictly necessary to do this, because postPatch ends up
in drvAttrs anyway, it's probably better to use overridePythonAttrs so
we don't run into problems when the underlying implementation of
buildPythonPackage changes.

Since 67651d80bc the requests package now
depends on certifi, which in turn provides the CA root certificates that
we need to replace.
It might also be a good idea to actually patch certifi with our version
of cacert by default so that if we want to override and/or add something
we only need to do it once.

The enableSSL option has been deprecated in
a912a6a291, so we switch to using onlySSL.
I've also explicitly disabled enableACME, because this is the default
and we don't actually want to have ACME enabled for a host which runs an
actual ACME server.

The test here is pretty basic and only tests nginx, but it should get us
started to write tests for different webservers and different ACME
implementations.

These modules implement a way to test ACME based on a test instance of
Letsencrypt's Boulder service. The service implementation is in
letsencrypt.nix and the second module (resolver.nix) is a support-module
for the former, but can also be used for tests not involving ACME.
The second module provides a DNS server which hosts a root zone
containing all the zones and /etc/hosts entries (except loopback) in the
entire test network, so this can be very useful for other modules that
need DNS resolution.
Originally, I wrote these modules for the Headcounter deployment, but
I've refactored them a bit to be generally useful to NixOS users. The
original implementation can be found here:
https://github.com/headcounter/deployment/tree/89e7feafb/modules/testing
Quoting parts from the commit message of the initial implementation of
the Letsencrypt module in headcounter/deployment@95dfb31110:
This module is going to be used for tests where we need to
impersonate an ACME service such as the one from Letsencrypt within
VM tests, which is the reason why this module is a bit ugly (I only
care if it's working not if it's beautiful).
While the module isn't used anywhere, it will serve as a pluggable
module for testing whether ACME works properly to fetch certificates
and also as a replacement for our snakeoil certificate generator.
Also quoting parts of the commit where I have refactored the same module
in headcounter/deployment@85fa481b34:
Now we have a fully pluggable module which automatically discovers
in which network it's used via the nodes attribute.
The test environment of Boulder used "dns-test-srv", which is a fake
DNS server that's resolving almost everything to 127.0.0.1. On our
setup this is not useful, so instead we're now running a local BIND
name server which has a fake root zone and uses the mentioned node
attribute to automatically discover other zones in the network of
machines and generate delegations from the root zone to the
respective zones with the primaryIPAddress of the node.
...
We want to use real letsencrypt.org FQDNs here, so we can't get away
with the snakeoil test certificates from the upstream project but
now roll our own.
This not only has the benefit that we can easily pass the snakeoil
certificate to other nodes, but we can (and do) also use it for an
nginx proxy that's now serving HTTPS for the Boulder web front end.
The Headcounter deployment tests are simulating a production scenario
with real IPs and nameservers so it won't need to rely on
networking.extraHost. However in this implementation we don't
necessarily want to do that, so I've added auto-discovery of
networking.extraHosts in the resolver module.
Another change here is that the letsencrypt module now falls back to
using a local resolver, the Headcounter implementation on the other hand
always required to add an extra test node which serves as a resolver.
I could have squashed both modules into the final ACME test, but that
would make it not very reusable, so that's the main reason why I put
these modules in tests/common.
