728de762fd feat(nix/buildkite): support meta.timeout
This uses the nixpkgs convention of meta.timeout, and adds a
timeout_in_minutes field to the pipeline step in case its set.

Fixes https://b.tvl.fyi/issues/285.

09486d483c docs(nix-1p): import is a builtin, not a keyword

As noted there, some Nix syntax highlighters will colour `import`
differently (e.g. the Emacs nix-mode), but it's not technically a
keyword in the language.

44a5e14200 feat(nix/readTree): implement .skip-tree marker for subtree ignoring
With this change, readTree gains the ability to notice a `.skip-tree`
marker in addition to the `.skip-subtree` marker.

The behaviour of the new marker will completely ignore the folder that
the marker is located in (i.e. no node will be present for it in the
parent at all).

To make this work, the recursive function in readTree had to be
modified to return a sentinel value (noting that a tree has requested
to be skipped) which is then filtered out when constructing the list
of children. The actual `readTree` function is now a wrapper around
this inner, sentinel-yielding implementation which unwraps the result
set.

For obvious reasons, `.skip-tree` is not allowed at the top-level and
readTree will throw an error if it encounters it there.

Emitting dependencies on non-drv store paths from drv directDrvDeps is
fine and actually correct, even though the Nix 2.3 version can't do it
at the moment (but this would change when the placeholder implementation
is replaced using a drv parser). However, we can't necessarily determine
the dependencies of non-drv store paths because such store paths may be
binary files that can't be read in by readFile due to NUL bytes.

57d5988b34 feat(nix/dependency-analyzer): find deps among a list of known drvs
This was written with the same intention (and reuses a little of its
code) as cl/5060 and cl/5063: We want to be able to emit dependencies
between //nix/buildkite pipeline steps, so that no agent is occupied
with waiting on locks for derivations built by a different agent.

This dependency information is already available to the Nix store
implementation (e.g. via `nix-store --query --references`) and can also
be obtained in the Nix language which is important, since the pipeline
is generated at evaluation time. (Note: For Nix 2.3, you either need a
strong convention about how derivations expose their dependencies (which
we don't) or rely on store implementation internals (drv files).
For Nix 2.6 there is a better trick, but it also relies on the existence
of drv files.)

The actual task can be formulated as follows: Given a set of
derivations, calculate the the closest derivations also in the input
each derivation depends on. (We call these (next) known dependencies.)
This is crucial because pipeline step often depend on each other only
indirectly with any number of intermediate derivations. For cl/5064 I
determined that 6 intermediate layers is quite common for dependencies
that are perceived to be “direct”.

This problem is solved as follows:

1. Calculate the dependency graph of the combined dependency closure of
   all input derivations. This is quite easy and fairly quick thanks to
   the C++ implementation of builtins.genericClosure. One weak point of
   the current implementation is that the function to determine the
   direct derivation dependencies for Nix < 2.6 is quite hacky.

2. Take the graph from 1. and calculate a dependency graph that only
   connects the known derivations of the input, but retains all
   connections between them (minus intermediate nodes).

In practice the dependency graph is represented as an attribute set
mapping derivation paths to a list of derivation paths it depends on.
The second step is performed by adding a second list of known derivation
paths it depends on.

The main improvements over the previous concept (cl/5060 and cl/5063):

* We only try to find the closest known dependencies in the dependency
  graph whereas we would traverse emit dependencies for the entire
  dependency closure.

* We immediately store the calculation of the closest known dependency
  in the dependency graph, even for intermediate nodes. This avoids
  recalculating the connection (which was a big drawback of the previous
  approach) and makes the calculation itself cheaper.

You can run `mg build //nix/dependency-analyzer:example` to build a
visualization of the internal dependencies between `depot.ci.targets` as
discovered by dependency-analyzer.

The convention has changed to use `final` instead of `self` and `prev`
instead of `super`. This new convention is much easier to understand
especially for users that are new to Nix and Nixpkgs.

This change is notable in the Nixpkgs project code. I added a note
mentioning that the official documentation hasn't been update with
this information. The documentation is currently undergoing an
overhaul and that is why I believe this hasn't been reflected in the
nixpkgs documentation as of yet.

335bf6900d fix(nix/buildkite): follow parent skip behavior in extra steps
We found a bug after updating to latest tvl-kit which broke
incremental releases.

Bug was related to the fact that extra steps skip attribute had
precedence over parent configuration. This is a desired behavior when
extra step is explicitly set to `skip=true` but otherwise it must
follow parent.

Due to extra step normalization skip parameter is always set to false
if not explicitly set.

Along the way, I'm adding support for setting skip attribute on extra
steps as string so that people can define skip reasons.

The bug was introduced by commit:
b9d79109d feat(ops/buildkite): Allow skip of individual steps

0c178a0ef6 chore(3p/sources): Bump channels & overlays
Upstream nixpkgs removed a lot of aliases this time, so we needed to do
the following transformations. It's a real shame that aliases only
really become discoverable easily when they are removed.

* runCommandNoCC -> runCommand
* gmailieer -> lieer
  We also need to work around the fact that home-manager hasn't catched
  on to this rename.
* mysql -> mariadb
* pkgconfig -> pkg-config
  This also affects our Nix fork which needs to be bumped.
* prometheus_client -> prometheus-client
* rxvt_unicode -> rxvt-unicode-unwrapped
* nix-review -> nixpkgs-review
* oauth2_proxy -> oauth2-proxy

Additionally, some Go-related builders decided to drop support for
passing the sha256 hash in directly, so we need to use the generic hash
arguments.

8fa3bc7137 feat(buildkite/mkPipeline): allow fast failure for build steps
This is supposed to help with resource wasting in situations when
multiple dynamic steps depend on a failing derivation. Cost of
failure currently is `C = T * D` where:
 - T -> time to compile the failing derivation
 - D -> amount of CI targets depending on a failing derivation

Switching to `Fail Fast` limits it to just T (time of a single
failure). Which helps a lot, especially while upgrading nixpkgs.

Fast fail at this moment is in preview, so to enable it:
 - Enable `Fail Fast` feature at pipeline or organization level
 - Set `cancelOnBuildFailing` parameter to true for `mkPipeline`

049ec22943 feat(nix/buildLisp): re-enable CCL
The problem went away once again, let's see how long it'll last this time.

As it turns out, CCL has a Unicode Standard conforming string
implementation that doesn't allow the use of (lone) surrogate code
points, requiring us to disable a test in cl-json which tested the
behavior of en- and decoding of such a (technically illegal) string.

b9c31d6658 refactor(nix/buildkite): Optimise steps if builds are not enabled
Generating a release-only pipeline skips a bigger chunk of eval this
way (the step itself is never actually evaluated, which means we never
actually compute the drv), which can be quite beneficial in terms of
evaluation time.

build phase is not active.

This is required to actually decouple the phases.

56a97a0337 refactor(nix/buildkite): Explicit support for build phases
Previously the extra steps were roughly divided into steps that run
"at build time" (i.e. before we publish results to Gerrit), and
"post-build" (i.e. later on).

In practice, these are something like a build/release pairing, where
steps running after the build results are returned are mostly run for
side-effects (e.g. publishing git subtrees to external repos).

This refactoring makes this distinction explicit in //nix/buildkite
and changes the extraSteps API with an explicit `phases` attribute
instead of the previous `postStep` attribute.

In practice the previous API is still supported, but will throw
evaluation warnings until an arbitrarily chosen cutoff date of
2022-10-01 at which point we will change using it into a hard error.

This uncovered a few strange behaviours which we only accidentally
avoided, most of which I have left TODOs about and will clean up in
subsequent commits.

The purpose of this commit is to allow for separate evaluations of
only build or only release steps, for example if release steps are
evaluated in a slightly different context (e.g. with overridden
versioning that is not relevant to standard CI functionality).
