This implements the nix-specific base32 encoding and decoding, exposing
a subset of the API that the data-encoding crate provides.
Nix uses a custom alphabet, no padding, and encodes bytes in reverse
order. The latter one is the reason we can't just use the data-encoding
crate directly.
Three odd corner case tests ported over from go-nix failed. We opened
b/235 to further investigate.

This uses the `im::OrdMap` for `NixAttrs` to enable sharing of memory
between different iterations of a map.
This slightly speeds up eval, but not significantly. Future work might
include benchmarking whether using a `HashMap` and only ordering in
cases where order is actually required would help.
This switches to a fork of `im` that fixes some bugs with its OrdMap
implementation.

The conversion from im::Vector -> Vec is cheaper for NixList
construction (of course), so where possible we should make use of
that.
This updates most builtins dealing with lists to use Vector directly,
and marks the function constructing NixList from Vec as deprecated so
that we get appropriate warnings in places where it's still in use.
These places are currently inside of JSON serialisation logic which is
in flux right now, so lets leave them as-is until it's stabilised.

Lists are not the most performance-critical structure in Nix (that

Note that there are a handful of cases where we still go via `Vec`

currently be implemented directly using `im::Vector` because of a

Stat exposes metadata about a given blob,
such as more granular chunking, baos.
It implicitly allows checking for existence too, as asking this for a
non-existing Blob will return a Status::not_found grpc error.
The previous version returned a Status::not_found error on the Get
request too, but there was no chance to prevent the server from starting
to stream (except sending an immediate cancellation).
Being able to check whether something exists in a BlobStore helps to
prevent from uploading in first place.
The granular chunking bits are an optional optimization - if the
BlobStore implements no more granular chunking, the Stat response can
simply contain a single chunk.
Read returns a stream of BlobChunk, which is just a stream of bytes -
not necessarily using the chunking that's returned in the reply of a
Stat() call. It can be used to read blobs or chunks.

This type carries the information required for calculating a
span (i.e. the chunk and offset), instead of the span itself. The span
is then only calculated in cases where it is required (when throwing
errors).
This reduces the eval time for
`builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one
third*!
The data structure in chunks that carries span information reduces
in-memory size by trading off the speed of retrieving span
information. This is because the span information is only actually
required when throwing errors (or emitting warnings).
However, somewhere along the way we grew a dependency on carrying span
information in thunks (for correctly reporting error chains). Hitting
the code paths for span retrieval was expensive, and carrying the
spans in a different way would still be less cache-efficient. This
change is the best tradeoff I could come up with.

for tvix-eval. Please note that this is definitely not the final
version yet, but it's better than the previous API that either exposed
a side-effecting blackbox, or a very low-level "interface".
The basic idea is that an evaluation of some Nix code is requested by
a caller with various parameters, but not all callers are interested
in all of these parameters.
There are also some bits of information that are returned from an
evaluation that are not necessarily relevant to all callers.
To support this somewhat ergonomically, the API is built around an
`Evaluation` struct that is configured by the caller with the various
parameters and then "executed".

We might want to have a function that combines the dependencies of all

non-trivial so I'm leaving it as an exercise for someone else.

Introduces granular dependency builds using crate2nix, bootstrapped
off the generated configuration from the newly introduced
workspace (see cl/7533).
This commit checks in the generated Cargo.nix file which can be
regenerated with a parameterless invocation of `crate2nix generate` in
`//tvix`. I tried generating this in IFD, but it turned out to be
harder than what seemed worthwhile for now.
In this setup, the various build targets for Rust projects end up
being attributes of the imported `Cargo.nix` file at the `tvix.crates`
attribute. These still lack configuration, however, which has been
fixed in the various `default.nix` files of individual projects.
Note that we (temporarily) lose the ability to build tvix-eval's
benchmarks in CI. I haven't figured out what magic incantation summons
them from the void again ...
The `eval-okay-readDir` tests from both test suites have been disabled
because they fail for unknown reasons when run in this new derivation.
Somebody will have to debug it!

This relates to the (abandoned) cl/7256.
Introduces a Cargo workspace at //tvix that is primarily intended to
be used as a workaround for the annoying Nix+Rust tooling while having
a consistent set of dependencies.
This is driven in part by a desire to adopt crate2nix and get more
granular Nix builds for Tvix's Rust projects, and in part by a need to
split //tvix/eval into something providing the CLI (REPL etc.), and a
library providing eval, without significantly altering the structure
of build targets.
To accomplish this the workspace has been designed to allow projects
to remain independent build targets. I want to avoid lumping all the
projects together - something like //tvix/eval should always be
independent of other parts of tvix.
A helper function in //tvix/default.nix lets downstream naersk
projects construct a sparse root for the project which combines the
workspace's `Cargo.lock` with the project's own `Cargo.toml`.
Note that cargo commands in the workspace itself require the build
dependencies of _all_ projects to be present, which is currently a bit
annoying to accomplish.
This introduces some breakage:
1. It breaks usage of rust-analyser without being in a shell with the
dependencies of *all* Tvix projects, as it is not capable of
respecting only the subset of dependencies for a part of the
workspace.
2. It is no longer possible to run tests using `cargo test`, as the
test generation crate we use does not work with workspaces:
https://github.com/frehberg/test-generator/issues/6
This still works in the Nix build as we construct a Cargo project
that looks like it's not in a workspace there. Until somebody fixes
that crate / writes a new macro / does something else with the test
suite, the way to run the tests is through the Nix build.
Long-term we'll probably want to get rid of cargo completely, it's
just a big wart and most tooling works without it if correctly
configured, but we don't have time for that now.

This .envrc file causes additional software to be loaded, but there is
no way to opt-out even if the software is not desired:
1. If I opt-in (i.e. `direnv allow`) the file, additional stuff that I
don't need is injected into my environment in a blocking way.
2. If I opt-out, *all* of the depot configuration (including `mg`) is
unloaded, as direnv configurations do not trivially nest.
I have to work around this constantly by making the file contain just
the line `source_up` and then setting `--assume-unchanged` on the git
index to avoid accidentally committing the file changes.
This is kind of silly, the people who *want* this stuff to be loaded
should devise a mechanism that loads it automatically but is opt-in.
This could be done e.g. by gating something on environment variables,
or having a shell hook, or whatever. Breaking expectations that hold
elsewhere in depot is not okay, however.
If you manually want a shell for a project, run `mg shell` either with
a target specification for that project (e.g. `mg shell //tvix/store`)
or in the project's folder.
You can also just use standard nix-shell invocations.

When we start unrecursivifying (sp?) things, Rust's borrow checker
is going to be a headache; its magic only works when you use the CPU
stack as your call stack.
Fixing the borrow checker issues usually involves adding lots of
`clone()`s. Right now `NixList` is the only variant of `Value` that
isn't cheap to clone() -- all the others are either a wrapper around
Rc or else are of bounded size.
Note that this requires dropping the `DerefMut for NixList` instance
and using `Vec<Value>` instead in those situations.

To work around this we clone the values for now. There might be some
optimisations possible like checking for thunk equality directly and
short-circuiting on that (we have to check what Nix does).

It is very confusing that this opcode is called DataLocalIdx, but it
carries a StackIdx rather than a LocalIdx. It seems like this
really ought to be called DataStackIdx, but maybe I've
misunderstood; if so please explain it to me.

We have to be careful implementing `builtins.groupBy`, since the
list may contain thunks, and tvix's to_xxx() functions do not work
on thunks.

The impl Display for NixAttrs needs to wrap double quotes around any
keys which are not valid Nix identifiers. This commit does that,
and adds a test (which fails prior to this commit and passes after
this commit).

If self.depth > other.depth then self is deeper than other, so self
is *below* other, not above it. Let's just inline the function.

It isn't possible to implement PartialEq properly for Value, because
any sensible implementation needs to force() thunks, which cannot be
done without a `&mut VM`.
The existing derive(PartialEq) has false negatives, which caused the
bug which cl/7142 fixed. Fortunately that bug was easy to find, but
a silent false negative deep within the bowels of nixpkgs could be a
real nightmare to hunt down.
Let's just remove the PartialEq impl for Value, and the other
derive(PartialEq)'s that depend on it.

The current implementation of nix_eq will force one level of thunks
and then switch to the (non-forcing) rust Eq::eq() method. This
gives incorrect results for lists-of-thunks.
This commit changes nix_eq() to be recursive.
A regression test (which fails prior to this commit) is included.
This fix also causes nix_tests/eval-okay-fromjson.nix to pass, so it
is moved out of notyetpassing.

We're getting close to the finish line, folks.
I went through the list of builtins and there are only 33 that
remain unimplemented. I've marked them, and indicated which are
ready to be implemented vs which are waiting for other things.
We can delete this column from the table once everything is
implemented.

I believe that the currentTime, findFile, hashFile, pathExists,
readDir, path (unless ?sha256), and readFile builtins are impure.
This commit marks them as such in docs/builtins.md.
