Previously, `wait_for_console_text` would block indefinitely until there were lines
shown in the buffer.
This is highly annoying when testing for things that can just hang for some reasons.
This introduces a classical timeout mechanism via non-blocking get on the Queue.
This is useful whenever you want to diagnose the current state of UEFI
variables, to assert that bootloaders or boot programs (systemd-stub)
did their job correctly and set their variables accordingly.
In the future, it can enable inspecting SecureBoot keys also.
This warning was added a year and a half ago, but still no test in
NixOS directly instantiates the machine class, presumably because it's
not actually possible for a test to do so without losing
functionality. For example, there's no way for a NixOS test to access
the output directory that create_machine passes to the Machine
constructor.
This warning is therefore just contributing to alert fatigue for
users, who are unable to follow its advice. Once it's actually
possible to do what it suggests, the warning can be reintroduced.
Adds a new option to the virtualisation modules that enables specifying explicitly named network interfaces in QEMU VMs.
The existing `virtualisation.vlans` option is still supported for cases where the name of the network interface is irrelevant.
By adding this option indirection, a test can declare all by itself
that it needs a custom nixpkgs. This is a more convenient way of
going about this when the caller of the test framework receives a
`node.pkgs` unconditionally.
mkIf is unnecessary when the condition is statically known - that is
knowable before entering the module evaluation.
By changing this to a precomputed module, we support changing the
defined options to readOnly options.
This change is made for two reasons:
1. If `toString config.restartTriggers` containes `\n`, systemd unit
file will be ill-formed.
2. This change can limit length of the trigger, although it doesn't
matter in most cases.
This allows modules that declare their class to be checked.
While that's not most user modules, frameworks can take advantage
of this by setting declaring the module class for their users.
That way, the mistake of importing a module into the wrong hierarchy
can be reported more clearly in some cases.
`make-disk-image` is a tool for creating VM images. It takes an argument
`contents` that allows one to specify files and directories that should
be copied into the VM image. However, directories end up not at the
specified target, but instead at a subdirectory of the target, with a
nix-store-like path, e.g.
`/target/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-source`. See issue
https://github.com/NixOS/nixpkgs/issues/226203 .
This change adds a test for make-disk-image's contents directory
handling and adds a fix (appending `/` to rsync input directory names).
This closes issue https://github.com/NixOS/nixpkgs/issues/226203 .
What the code was trying to do was helpfully add a directory and
extension if none were specified, but it did this by checking whether
the filename was composed of a very limited character set that didn't
even include dashes.
With this change, the intention of the code is clearer, and I can put
dashes in my screenshot names.
the old method of pasting parts of options.json into a markdown document
and hoping for the best no longer works now that options.json contains
more than just docbook. given the infrastructure we have now we can
actually render options.md properly, so we may as well do that.
options processing is pretty slow right now, mostly because the
markdown-it-py parser is pure python (and with performance
pessimizations at that). options parsing *is* embarassingly parallel
though, so we can just fork out all the work to worker processes and
collect the results.
multiprocessing probably has a greater benefit on linux than on darwin
since the worker spawning method darwin uses is less efficient than
fork() on linux. this hasn't been tested on darwin, only on linux, but
if anything darwin will be faster with its preferred method.
