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.

Fix a bug introduced by 2ca153141 (I merged the wrong patchset).
Issue happens when pipeline is split by phases into independent
evals (e.g. build/release/deploy).
Splitting extra steps requires knowledge of all known phases,
otherwise pipeline evaluation fails due to extra steps from inactive
phases.

It uses discrDef internally, but passes `null` as the default tag name,
causing Nix to drop the attribute and return an empty attribute set if
the default case is hit. Consequently we need to check for the empty
attribute set, not `null` to figure out if there was no match found.
We can also test this behavior using `assertThrows` which was introduced
after the tag library was originally written.

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.

We found a bug after updating to latest tvl-kit which broke

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

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`

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).

There is a reoccuring problem in readTree-type repositories that use
nix-shell, where evaluation of the full set of dependencies that
should be made available to users takes a noticeable amount of time,
slowing down operations when `direnv` is involved.
In depot, we have so far fixed this by maintaining a manual `//bin`
directory which contains a set of symlinks to a central dispatch
script that can dispatch to various tools in depot lazily.
This script can instead be generated ad-hoc by Nix (pretty fast if we
can make assumptions like `git` and `nix-build` existing on user's
machines already) and added to $PATH.
The function introduced in this commit implements the logic for that.
The structure of the script is based on the existing
`//bin/__dispatch`.
This does not yet switch depot's envrc to use this new method of
installing dependencies lazily.

This was useful to have in CI, e.g. when targeting a specific NixOS
system. The actual result symlink which is printed is not useful.
Alternative solution would be to change the wrapping of this so that
we conditionally create the symlink for extra steps, but I think it's
not worth the complexity of evaluating the step twice.

This changes the logic for build pipeline generation to inspect
an (optional) parentTargetMap attribute which contains the derivation
map of a target commit.
Targets that existed in a parent commit with the same drv hash will be
skipped, as they are not considered to have changed.
This does not yet wire up any logic for retrieving the target map from
storage, meaning that at this commit all targets are always built.
The intention is that we will have logic to fetch the target
map (initially from Buildkite artefact storage), which we then pass to
the depot via externalArgs when actually generating the pipeline.

Always create a structure that maps all targets to derivations, and

The file is always uploaded to Buildkite as an artifact. This allows
for retrieving it based on the commit ID in a Buildkite GraphQL query.
By default, Buildkite stores artefacts for 6 months. Storage location
can be overridden (with custom retention) through some environment
variables, but for now at TVL the Buildkite-managed storage is fine.
See also: https://buildkite.com/docs/pipelines/artifacts
In the subsequent filtering implementation, when diffing commits
across a time-range that exceeds artefact retention time, we should
simply default to building everything.

This is a move towards exposing several readTree-related features from

Note that this has a small functional change: In error messages of the
function, the notation for accessing Nix attributes is now used rather
than the Perforce-style `//` notation common in TVL.
For example, an error at `//web/tvl/logo` will produce `web.tvl.logo`
in the error message (which corresponds to the readTree attribute
itself).
This makes more sense for non-TVL consumers of readTree, as the
Perforce-style notation is custom to us specifically.

In order to make readTree import symlinked directories I've been looking
into how to detect if a symlink points to a directory (since this would
allow us to use symlinks for //nix/sparseTree). I've found a hack for
this:
symlinkPointsToDir = path: isSymlink path &&
builtins.pathExists (toString path + "/.")
Unfortunately it doesn't seem to be possible to distinguish whether the
symlink target does not exist or is a regular file.
Since it's possible, I thought might as well add this to
`pathType`. To make returning the extra information workable, I've
elected to use the attribute set layout used by `//nix/tag`. This
doesn't require us to depend anything (as opposed to yants), but gives
us pattern matching (via `nix.tag.match`) and also quite idiomatic
checking of pathTypes:
pathType ./foo ? file
(pathType ./foo).symlink or null == "symlink-directory"
Nonexistent paths are encoded like this:
pathType ./foo ? missing
Of course we can't use this in readTree (since it must be zero
dependency), but we can easily inline this hack at some point.
