It is a reasonable enough assumption that depot.path will have the store
path name "depot". In the past this used to be the case, since most
people would checkout the repository as "depot" (funnily enough in the
past, you wouldn't have been able to substitute some things if you used
a different name). When we started to use cleanSource for depot.path the
default name "source" would be assigned, breaking e. g. the assumptions
of //web/todolist. We now set to "depot" statically.

Discovering CI targets is relevant to all readTree consumers and this

This is often used when bootstrapping a repository with readTree,
before lib is available. Having this definition in readTree is more
convenient than copy&pasting it around to callsites.

This is generally useful for readTree users and should be part of
readTree itself.
This is a move towards exposing several readTree-related features from
the library itself, in the future also including logic like 'gather'.
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.

This folder is used for some TVL corp stuff, like the website and
maybe some documents and future projects, that are not under the same
license as the rest of depot.
To avoid accidental licensing issues, access to it is restricted to
other stuff within //corp.
In general, TVL corp projects *should* also be free software and live
outside of //corp - the folder is primarily intended for stuff that is
relevant to the company operations (also for the sake of
transparency).

This refactors the readTree filter which disallows access to //users
from outside of //users into a reusable function.
The only change in functionality is that the error message has changed
slightly. I thought it is useful to keep the message consistent (i.e.
always including a path), thus only a part of the error is templated
in (describing the reason for why a specific sub path is unavailable).

This change adds a new attribute to readTree nodes, `__readTreeChildren`
which is a list of attribute names added to this node by readTree.
This is then used by `gather` for `ci.targets` to avoid evaluating
attributes unnecessarily. Especially since Nix is not as lazy as we'd
like when determining types (i. e. child ? __readTree needs to force
`child` even when it's not an attribute set), evaluating attributes
unnecessarily is sometimes problematic.

Since //web/bubblegum depends on nint, we need to move it to a non user

Note that this likely doesn't mean greater stability (which isn't

elaborate calling convention to allow for additional useful features.

Code under this depot path is essentially unstable and potentially
unreviewed - this is a good thing (people can play around with cursed
stuff all they want), but we should not make the rest of the
repository depend on any of it.
Any cursed things that are required outside of users can be moved to a
different depot path if people agree with that.

Plumbs an additional internal argument through readTree that indicates
whether the top-level of a tree is being read, and avoids recursing
into itself in that case. This changes the externally visible
behaviour of readTree (it is now expected to be called a level higher
than previously).
This allows us to reduce the amount of boilerplate needed to bootstrap
the TVL repository (by not having to specify the individual folders
that need to be read).
For reasons related to an infinite recursion we could not (be bothered
to) debug, the top-level `config` key (which held the attribute set
passed on by readTree) has been removed. This is not needed, as it is
already passed on by readTree ...

Adds a conditional build step that only runs on the canon branch, and
only if :duck: (the status reporting step) succeeds, which creates a
new Nix GC root for all depot targets named `depot-canon`.
In practice this might be a bit racey, as canon builds are not
guaranteed to succeed in order (though it is likely). This shouldn't
matter much in practice: We only want to prevent rebuilds of the whole
world.

This lets the import of the depot root accept an additional argument
called `externalArgs`, which can be used to pass additional arguments
into a depot package set.
This is used in //third_party/nixpkgs for replacing the source of the
nixos-unstable channel with a path. With this we can bisect the
nixpkgs used in third_party easily.

Please read b/108 to make sense of this.
This gets rid of the explicit list of exposed packages from nixpkgs,
and instead makes the entire package set available at
`third_party.nixpkgs`.
To accommodate this, a LOT of things have to be very slightly shuffled
around. Some of this was done in already submitted CLs, but this
change is unfortunately still quite noisy.
Pay extra attention to:
* overlay-like functionality that was partially moved to actual
overlays (partially as in, the minimum required to get a green
build)
* modified uses of the package set path, esp. in NixOS systems
Special notes:
* xanthous has been disabled in CI because of issues with the Haskell
overlay
* //third_party/nix has been disabled because of other unclear
dependency issues
Both of these will be tackled in a followup CL.

We have naturally evolved a distinction between logical and physical
targets.
Physical targets are those which correspond directly to a tree
location on disk and can be built with `-A path.to.files`, while
logical targets are those that are exported from within an expression
but do not have a corresponding file on disk.
This change adds support for exporting logical targets from any tree
location by adding a `meta.targets` attribute containing keys into
itself, which will be consumed by the CI target gathering logic and
included in the generated pipeline.
Note that the labels for subtargets are syntactically different to
emphasise that they do not correspond to a file location. For example,
this change enables 'ops.nixos.whitbySystem' as a subtarget, which is
labeled in CI as `ops/nixos:whitbySystem`.

Create the pipeline by outputting a file that contains nix-build
invocations for each target's *derivation path*.
Each invocation has a generated Nix expression passed to it with `-E`
which fetches the correct target from the tree while correctly
handling targets with strange characters (such as in Go-packages).
This makes it possible to run target-level granular pipelines. We're
getting somewhere!

Automatically walk the entire depot tree and pick out things that are
"buildable", then include them in the attribute `ci.targets` (which is
now also the target for CI builds).
A long time ago, in a land far away, we (well, I, at the time) had a
prototype of this which ran into constant issues with infinite
recursions while trying to walk the tree. In fact, this is why
readTree originally gained the `__readTree`-attribute which marks
things that were imported automatically.
Based on some code edef whipped up earlier (with the breakthrough
being that we also add the attribute to top-level folders, which
suddenly resolves a whole bunch of problems), I've now implemented
this actually working version.
At the moment all builds still happen as one big bag of builds, but at
some point we will granularise this.

These categories separate CI targets, which hopefully avoids the
out-of-space errors we have been seeing on Sourcehut.
The sets of CI build targets are made available in the depot itself so
that besadii can be updated to create a new build for each target
group.
For convenience, 'ciBuilds' contains an '__allTargets' attribute which
combines the contents of each target batch - this makes it possible to
still invoke a build for everything by using:
nix-build -A ciBuilds.__allTargets
Note: Some targets that were previously built in CI aren't anymore,
most importantly my NixOS systems which don't fit on Sourcehut.

* depot.third_party is additionally passed as 'pkgs' (for

Exposes readTree from the package set but with a twist: It's exposed

This is required for some things that expect package sets to be

|
|
Instead of polluting the repository namespace with the list of CI

Currently the list of projects to be built by CI is still hardcoded,
but this will be fixed soon.

Due to a missing feature in readTree I can't currently generate this

* overrides are now loaded from a separate `override` folder just

* third-party packages have moved into the `third_party` attribute set
