Rationale
---------
Currently, tests are hard to discover. For instance, someone updating
`dovecot` might not notice that the interaction of `dovecot` with
`opensmtpd` is handled in the `opensmtpd.nix` test.
And even for someone updating `opensmtpd`, it requires manual work to go
check in `nixos/tests` whether there is actually a test, especially
given not so many packages in `nixpkgs` have tests and this is thus most
of the time useless.
Finally, for the reviewer, it is much easier to check that the “Tested
via one or more NixOS test(s)” has been checked if the file modified
already includes the list of relevant tests.
Implementation
--------------
Currently, this commit only adds the metadata in the package. Each
element of the `meta.tests` attribute is a derivation that, when it
builds successfully, means the test has passed (ie. following the same
convention as NixOS tests).
Future Work
-----------
In the future, the tools could be made aware of this `meta.tests`
attribute, and for instance a `--with-tests` could be added to
`nix-build` so that it also builds all the tests. Or a `--without-tests`
to build without all the tests. @Profpatsch described in his NixCon talk
such systems.
Another thing that would help in the future would be the possibility to
reasonably easily have cross-derivation nix tests without the whole
NixOS VM stack. @7c6f434c already proposed such a system.
This RFC currently handles none of these concerns. Only the addition of
`meta.tests` as metadata to be used by maintainers to remember to run
relevant tests.
Referencing modulesPath in NixOS configurations can cause evaluation
errors in restricted mode. If used as `${modulesPath}` (as in all
use-sites in nixpkgs) the modules subtree is copied into its own store
path. Access to this path will be forbidden in restricted mode.
Converting to a string solves this issue.
`${builtins.toString modulesPath}` will point to a subdirectory of the
nixpkgs tree out of which evalModules is called.
This change converts modulesPath to a string by default so that the
call-site doesn't have to anymore.
Previously, setting "privateNetwork = true" without specifying host and
local addresses would create unconfigured interfaces: ve-$INSTANCE on the host
and eth0 inside the container.
These changes is rebased part of the original PR #3021.
With this option enabled, before creating file/directories/symlinks in baseDir
according to configuration, old occurences of them are removed.
This prevents remainders of an old configuration (libraries, webapps, you name
it) from persisting after activating a new configuration.
100GB breaks cptofs but 50GB is fine and benchmarks shows it takes the same time as building the demo VBox VM with a 10GB disk
+ enabled VM sound output by default
+ set USB controller in USB2.0 mode
+ add manifest file in the OVA as it allows integrity checking on imports
* journald: forward message to syslog by default if a syslog implementation is installed
* added a test to ensure rsyslog is receiving messages when expected
* added rsyslogd tests to release.nix
The nixos-manual service already uses w3m-nographics for a variant that
drops unnecessary junk like various image libraries.
iso_minimal closure (i.e. uncompressed) goes from 1884M -> 1837M.
