cb2cf3f6b7 fix(tvix/castore/grpc/svc_wrapper): expose chunks() over gRPC
The Stat() method was just always signalling no granular chunks are
available. However, as we now have a .chunks() method, we can expose it
over gRPC.

5f0f4ea374 refactor(tvix/eval): Box Value::String
NixString is *quite* large - like 80 bytes - because of the extra
capacity value for BString and because of the context. We want to keep
Value small since we're passing it around a lot, so let's box the
NixString inside Value::String to save on some memory, and make cloning
ostensibly a little cheaper

8caa097ba8 feat(tvix/eval): Don't emit OpForce for non-thunk constants
In the compiler, skip emitting an OpForce if the last op was an
OpConstant for a non-thunk constant. This gives a small (~1% on my
machine) perf boost, eg when evaluating hello.outPath:

    ❯ hyperfine \
        "./before --no-warnings -E '(import <nixpkgs> {}).hello.outPath'" \
        "./after --no-warnings -E '(import <nixpkgs> {}).hello.outPath'"
    Benchmark 1: ./before --no-warnings -E '(import <nixpkgs> {}).hello.outPath'
      Time (mean ± σ):      1.151 s ±  0.022 s    [User: 1.003 s, System: 0.151 s]
      Range (min … max):    1.123 s …  1.184 s    10 runs

    Benchmark 2: ./after --no-warnings -E '(import <nixpkgs> {}).hello.outPath'
      Time (mean ± σ):      1.140 s ±  0.022 s    [User: 0.989 s, System: 0.152 s]
      Range (min … max):    1.115 s …  1.175 s    10 runs

    Summary
      ./after --no-warnings -E '(import <nixpkgs> {}).hello.outPath' ran
        1.01 ± 0.03 times faster than ./before --no-warnings -E '(import <nixpkgs> {}).hello.outPath'

d3d41552cf refactor(tvix/eval): Don't double-box Path values
PathBuf internally contains a heap pointer (an OsString), so we were in
effect double-boxing here. Removing the extra layer by making
Tvix::Value represented by a Box<Path> rather than a Box<PathBuf> saves
us an indirection, while still avoiding the extra memory overhead of the
capacity which was the reason we were boxing PathBuf in the first place.

201173afac fix(tvix): Represent strings as byte arrays
C++ nix uses C-style zero-terminated char pointers to represent strings
internally - however, up to this point, tvix has used Rust `String` and
`str` for string values. Since those are required to be valid utf-8, we
haven't been able to properly represent all the string values that Nix
supports.

To fix that, this change converts the internal representation of the
NixString struct from `Box<str>` to `BString`, from the `bstr` crate -
this is a wrapper around a `Vec<u8>` with extra functions for treating
that byte vector as a "morally string-like" value, which is basically
exactly what we need.

Since this changes a pretty fundamental assumption about a pretty core
type, there are a *lot* of changes in a lot of places to make this work,
but I've tried to keep the general philosophy and intent of most of the
code in most places intact. Most notably, there's nothing that's been
done to make the derivation stuff in //tvix/glue work with non-utf8
strings everywhere, instead opting to just convert to String/str when
passing things into that - there *might* be something to be done there,
but I don't know what the rules should be and I don't want to figure
them out in this change.

To deal with OS-native paths in a way that also works in WASM for
tvixbolt, this also adds a dependency on the "os_str_bytes" crate.

85421b7f97 feat(tvix/store/nar-info): Support async blob upload
Right now all blob uploads are performed synchronously, this means if a
NAR contains many small files, the import time is dominated by round
trip time to the blob service. For small files, we can buffer them in
memory and upload them asynchronously to the blob service. Before
returning we make sure to join all the uploads to make sure they
complete successfully before responding OK.

This reduces time to import a bash-interactive closure on my machine
from 1m19s to 7s.

1f1a42b4da feat(tvix/castore): ingestion does DFS and invert it
To make use of the filtering feature, we need to revert the internal walker to a real DFS.

We will therefore just invert the whole tree by storing all of its
contents in a level-keyed vector.

This is horribly expensive in memory, this is a compromise between CPU
and memory, here is the fundamental reason for why:

When you encounter a directory, it's either a leaf or not, i.e. it
contains subdirectories or not.

To know this fact, you can:

- wait until you notice subdirectories under it, i.e. you need to store
  any intermediate nodes you see in the meantime -> memory penalty.
- getdents or readdir on it to determine *NOW* its subdirectories -> CPU
  penalty and I/O penalty.

This is an implementation of the first proposal, we pay memory.

In practice, we are paying O(#nb of nodes) in memory.

There's a smarter albeit much more complicated algorithm that pays only
O(\sum_i #siblings(p_i)) nodes where (p_1, ..., p_n) is the path to a leaf.

which means for:

             A
            / \
           B   C
          /   / \
         D   E   F

We would never store D, E, F but only E, F at a given time.
But we would still store B, C no matter what.

We propagate a `TvixStoreIO` as the `state` of our derivation-specific
builtins in the glue crate.

The evaluators `io_handle` itself is using a Rc<dyn EvalIO>.

An earlier version of TvixStoreIO was also introducing generics over the
different internal services themselves, but we opted for instead
hardcoding this to Arc<dyn …> for the sake of less macro voodoo.

for context strings matters.

It already smoked out multiple mistakes and potential bugs and non-deterministic result from the evaluator.

It uses a similar technology as the one in the tvix-eval albeit we instantiate a fully fledged evaluator

We copy the files instead of symlinking them because crates are built in
isolation, so symlinks cannot work.

75cc52ddb1 fix(tvix/eval): getContext merges underlying values
Previously, we were assembling very naively an attribute set composed of context we saw.

But it was forgetting that `"${drv}${drv.drvPath}"` would contain 2 contexts with the same key, but
with different values, one with `outputs = [ "out" ];` and `allOutputs = true;`.

Following this reasoning and comparing with what Nix does, we ought to merge underlying values systematically.

Hence, I bring `itertools` to perform a group by on the key and merge everything on the fly, it's not
beautiful but it's the best I could find, notice that I don't use
`group_by` but I talk about group by, that is, because `group_by` is a
`group_by_consecutive`, see
https://github.com/rust-itertools/itertools/issues/374.

Initially, I tried to do it without a `into_grouping_map_by`, it was akin to assemble the final `NixAttrs` directly,
it was less readable and harder to pull out because we don't have a lot of in-place mutable functions on
our data structures.

d516ce56b1 feat(tvix/glue/derivationStrict): support __structuredAttrs
This adds support to handle the __structuredAttrs argument, which can be
passed to builtins.derivationStrict.

If __structuredAttrs is passed, and set to true, most of the arguments
passed to builtins.derivationStrict are not simply coerced to a string
and passed down to "environments", but instead kept in a more structured
fashion.

Inside ATerm, which is what's relevant as far as path calculation is
concerned, a virtual `__json` environment variable is present,
containing these structured values.

Inside Builds, these structured values are not made available as an
environment variable, but a JSON file (and source-able bash script).

This will need to be respected once we start emitting BuildRequests,
and for that we can probably just parse the `__json` key in
Derivation.environment again - or keep this additionally in
non-serialized form around during Evaluation.
No matter what, this is left for a followup CL.

The existing handle_derivation_parameters and populate_outputs helper
function were removed, as __structuredAttrs causes quite a change
in behaviour, and so handling both in the same place makes it more
readable.

There's some open questions w.r.t. string contexts for structured attrs
itself. A TODO is left for this, but at least path calculation for
individual structured attrs derivations are correct now.

Part of b/366.

This means, multiple nodes can be returned, so return a Vec.

Additionally, use a proto::node::Node (the naked enum), rather than
proto::Node, which wraps this in an optional struct field until

7d51193f7d refactor(tvix/store/nar/renderer): don't require Arc, Clone or Sync
To render NARs, we're fine with a simple AsRef to a BlobService and
DirectoryService. We just need to have the function pass back the
references, so we can reuse it after the recursion.

719cbad871 feat(tvix/castore/blobsvc): add chunks method
This adds support to retrieve a list of chunks for a given blob to the
BlobService interface.

While theoretically all chunk-awareness could be kept private inside
each BlobService reader, we'd not be able to resolve individual chunks
from different Blobservices - and due to this, not able to substitute
chunks we already have in a more local store.

This function allows asking a BlobService for the list of chunks,
leaving any actual fetching up to the caller (be it through individual
calls to open_read), or asking another store for it.

7dcb37fc52 feat(tvix/eval): context-aware substring
`substring` has a very funny behavior when it comes to empty strings,
it propagates the context too, this is used in nixpkgs to attach context
to strings without using any builtin: `lib.addContextFrom`.

7a84a8fe89 fix(nix-compat/nix-hash): relax padding requirements
Nix is quite tolerant when it comes to parsing SRI hashes and their
padding (and only for SRI hashes, it funnily is strict about that in the
non-SRI-hash case).

Nix essentially accepts any number of padding characters, no matter if
it's too much or too little. So we do the only sane thing - simply strip
all padding characters, and parse it with BASE64_NOPAD and the length
the algo uses.

You can make one available by running:

```
docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 6831:6831/udp \

  -p 14269:14269 \
  -p 9411:9411 --rm \
  jaegertracing/all-in-one:1.42
```

Started like that, jaeger brings a web interface at
http://localhost:16686/search

As documented in
https://docs.rs/opentelemetry-otlp/latest/opentelemetry_otlp/, you can
point this to another location by setting `OTEL_EXPORTER_OTLP_ENDPOINT`.

0c22454bb9 fix(tvix/eval): add stack depth assertion to OpReturn
I'm still trying to work out the exact stack invariants for tvix.
We really should add assertions for them; getting the stack messed
up is no fun.  This commit adds one simple assertion.  It also adds
a missing stack-push (my mistake) in one place, which was uncovered
by the assertion.

d07600dbca fix(tvix/eval/value): correctly emit spaces when coercing lists
r/7176 introduced an incorrect assumption was the benefit of the
nonrecursive coercion algorithm, namely that a coercion operation always
returns a non empty string. This allows to detect whether we are
coercing a list or not by checking if the intermediate result is empty
or not. Unfortunately, coercing null and false yields an empty string,
so we need to explicitly track whether we are coercing a list.

Updated the test case to hopefully catch similar bugs in the future. I'm
not a hundred percent certain I have not introduced a new edge case with
this, so it may be interesting to add a prop test case for this to
nix_oracle down the line. At least lists are the only nested data
structures that can be serialized as nested data structures, so the
problem is kind of limited.

cl/10378 did already move store/fs to castore/fs, but we kept the tests
in tvix-store, as they were populating a PathInfoService to make nodes
appear in the mount root.

Update these tests to now just insert root nodes into a BTreeMap, and
ensure we can use that as a RootNodes too.

a5167c508c chore(tvix): move store/fs to castore/fs
With the recent introduction of the RootNodes trait, there's nothing in
the fs module pulling in tvix-store dependencies, so it can live in
tvix-castore.

This allows other crates to make use of TvixStoreFS, without having to
pull in tvix-store.

For example, a tvix-build using a fuse mountpoint at /nix/store doesn't
need a PathInfoService to hold the root nodes that should be present,
but just a list.

tvix-store now has a pathinfoservice/fs module, which contains the
necessary glue logic to implement the RootNodes trait for a
PathInfoService.

To satisfy Rust orphan rules for trait implementations, we had to add a
small wrapper struct. It's mostly hidden away by the make_fs helper
function returning a TvixStoreFs.

It can't be entirely private, as its still leaking into the concrete
type of TvixStoreFS.

tvix-store still has `fuse` and `virtiofs` features, but they now simply
enable these features in the `tvix-castore` crate they depend on.

The tests for the fuse functionality stay in tvix-store for now, as
they populate the root nodes through a PathInfoService.

Once above mentioned "list of root nodes" implementation exists, we
might want to shuffle this around one more time.

Fixes b/341.

6815572274 refactor(tvix/store/fs): Decouple TvixStoreFs from Nix concepts
To support tvix builds, we need to be able to use the `TvixStoreFs` to
materialize the sandbox's /nix/store filesystem with just the list of
inputs needed for the build. Currently we'd need to seed an in-memory
`PathInfoService`, which includes more functionality than what is
required for `TvixStoreFs`. Additionally, the `PathInfoService` is
specific to Nix. By decoupling `TvixStoreFs` and `PathInfoService`,
we allow for usage of `TvixStoreFs` with `tvix-castore` without needing
a `PathInfoService`.

This introduces a new `RootNodes` trait which provides a way for the
filesystem to look up CA nodes via their basename in the root directory
of the filesystem. We then implement `RootNodes` for any
`PathInfoService`. Additionally, the filesystem root inode tracker now
stores basenames rather than `StorePath`s since `StorePath`s are
specific to Nix.

As a followup we can rename `TvixStoreFs` to `TvixCaStoreFs` and move
it to the `castore` crate (or its own crate).

e4d6d20aa7 test(tvix/glue): add nonexisting_path_without_import test
This moves the failing example from cl/10285 into its separate test
case.

There were multiple complications: tvix-[ca]store was panicking in some
places, rather than returning an error. This is now fixed.

It needs to live in tvix-glue, so we actually have a "proper" EvalIO
interface doing something.

> toString ({ line = 42; col = 42; file = /deep/thought; }.file)

Should not cause an error, because it shouldn't trigger an import, but
leave the path as-is, and not care about it not being present.

7165ebc43b fix(tvix/eval): remove incorrect imports when coercing
The default behavior of string coercion in C++ Nix is to weakly coerce
and import to store if necessary. There is a flag to make it strongly
coerce (coerceMore) and a flag that controls whether path values have
the corresponding file/directory imported into the store before
returning the (store) path as a string (copyToStore). We need to
implement our equivalent to the copyToStore (import_paths) flag for the
benefit of weak coercions that don't import into the store (dirOf,
baseNameOf, readFile, ...) and strong coercions that don't import into
the store (toString).

This makes coerce_to_string as well as CoercionKind weirder and more
versatile, but prevents us from reimplementing parts of the coercion
logic constantly as can be seen in the case of baseNameOf.

Note that it is not possible to test this properly in //tvix/eval tests
due to the lack of an appropriate EvalIO implementation being available.
Tests should be added to //tvix/glue down the line.

This matches the behavior of C++ Nix more closely where the decision is
made based on the first type based to ExprConcatStrings:
1f93fa2ed2/src/libexpr/eval.cc (L1967-L2025)

Note that this doesn't make a difference in any successful
evaluation (at least to my knowledge), but ensures that our error
messages will match C++ Nix more closely, e.g. in the case of
`1 + "string"`.

8d4aa2c15c fix(tvix/eval): add unimplemented __curPos and builtins.filterSource
This commit adds __curPos (to the global scope, yuck) and
builtins.filterSource.  These are not implemented; forcing them will
produce the same result as `throw "message"`.

Unfortunately these two post-2.3 features are used throughout
nixpkgs.  Since an unresolved indentifier is a catchable error, this
breaks the entire release eval.  With this commit, it simply causes
those broken packages that use these features to appear as they are:
broken.

2949ee08f1 fix(tvix/eval): calling a catchable is catchable
When attempting to call a Value, if it is a Value::Catchable we must
not cause an uncatchable failure.  This commit simply reuses the
Value::Catchable as the result of attempting to call it.  This is
safe because nix is designed so that nix code cannot distinguish
between different catchable failures -- they all look the same to
the interpreted code.

This fixes b/351.

This commit adds Opcode::OpJumpIfCatchable, which can be inserted
ahead of most VM operations which expect a boolean on the stack, in
order to handle catchables in branching position properly.

Other than remembering to patch the jump, no other changes should be
required.

This commit also fixes b/343 by emitting this new opcode when
compiling if-then-else.  There are probably other places where we
need to do the same thing.

1ac57b0d1c feat(tvix/eval): nonrecursive coerce_to_string()
After this commit, the only non-builtins uses of generators are:

  - coerce_to_string() uses generators::request_enter_lambda()
  - Thunk::force() uses generators::request_enter_lambda()

That's it!  Once those two are taken care of, GenCo can become an
implementation detail of `builtins::BuiltinGen`.  No more crazy
nonlocal flow control within the interpreter: if you've got a GenCo
floating around in your code it's because you're writing a builtin,
which isn't part of the core interpreter.  The interpreter won't
need GenCos to talk to itself anymore.

Technically generators::request_path_import() is also used by
coerce_to_string(), but that's just because the io_handle happens to
be part of the VM.  There's no recursion-depth issue there, so the
call doesn't need to go through the generator mechanism
(request_path_import() doesn't call back to the interpreter!)

c92d06271d feat(tvix/eval): drop LightSpan::Delayed
LightSpan::Delayed was introduced in commit
bf286a54bc which claimed that "This
reduces the eval time for `builtins.length (builtins.attrNames
(import <nixpkgs> {}))` by *one third*!"

I am unable to reproduce this result.  In fact, dropping the
LightSpan::Delayed variant of the enum makes eval of the same
expression slightly faster!  I also tried a large evaluation
(pkgsCross...hello) and got similar results: slightly faster,
slightly less memory.  See git footers.

I suspect that there was some unrelated horrific inefficiency that
has since been fixed.  The avoided computation in `get_span()` is
nothing more than a binary search!  If this were in fact a major
performance issue we could simply precompute the mapping from
CodeIdx to Span when the Chunk becomes immutable (i.e. at the end of
the compilation process, when compiler backtracking is no longer a
concern).  Since a Span is just 64 bits this is not a space issue,
and since binary search is much simpler than compiling Nix
expressions it isn't a performance issue either.

Technically there is no longer any reason to have LightSpan since it
is now a single-variant enum.  However there is no rush to remove
it, since Rust will optimize its representation into the same thing
you'd get if you replaced LightSpan by Span.

ae28dc3ca6 test(tvix/eval): test for b/338 catchable hygiene problem
Commit 05f42519b5 fixed b/281 by
establishing a hygiene regimen to partition *catchable* errors
(i.e. those which tryEval can detect) from all other errors, like
internal VM failures or I/O errors (which Nix must not be allowed to
detect, since these errors are fundamentally impure).

Unfotunately there are still cases where tvix assumes that anything
other than Value::Bool means it should panic!().  I found another
one, and added a test case for it in:

  eval_okay_src_tests_tvix_tests_eval_okay_compare_ordering_catchable_nix

Not yet passing.

This commit rewrites Value::nix_cmp_ordering() into an equivalent
nonrecursive form.  Except for calls to Thunk::force(), the new form
no longer uses generators, and is async only because of the fact
that it calls Thunk::force().

I originally believed that this commit would make evaluation faster.
In fact it is slightly slower.  I believe this is due to the added
vec![] allocation.  I am investigating.

8a40f75c2d fix(tvix/eval): never use partial_cmp() (partial fix b/338)
This is part of a fix for b/338.

We should never use PartialOrd::partial_cmp().

All Nix types except floats are obviously totally-ordered.  In
addition, it turns out that because Nix treats division by zero
rather than producing a NaN, and because it does not support
"negative zero", even floats are in fact totally ordered in Nix.

Therefore, every call to PartialOrd::partial_cmp() in tvix is an
error.  We have to *implement* this function, but we should never
call it on built-in types.

Moreover, nix_cmp_ordering() currently returns an Option<Ordering>.
I'm not sure what was going on there, since it's impossible for it
to return None.  This commit fixes it to return simply Ordering
rather than Option<Ordering>.

72ece2e518 feat(tvix/eval): nonrecursive nix_eq()
This commit rewrites Value::nix_eq() into an equivalent.  Except for
calls to Thunk::force(), the new form no longer uses generators, and
is async only because of the fact that it calls Thunk::force().

I believed that the nonrecursive form would be faster.  It is, in
fact, slightly slower.  I believe this is due to the vec![]
allocation; I am investigating.

0c15a09b15 feat(tvix/cli): add macrobenchmark
This commit adds a simple MVP benchmark, built on our nix
infrastructure instead of cargo.  It simply runs `tvix-eval` inside
of GNU time, and prints the three essential statistics in a short
JSON blob.

You can run the benchmark with a simple `nix run`, like:

  nix run -f . tvix.cli.benchmark-hello
  nix run -f . tvix.cli.benchmark-firefox
  nix run -f . tvix.cli.benchmark-cross-firefox

Currently these blobs are stored only in the CI logs, which I'm sure
get garbage-collected at some point.  We should be putting them in
the git trailers, but that can wait for a future CL.

I tried using `cargo bench` for this but found it incredibly
frustrating.  Maybe I'm doing it wrong.  It seems to be designed for
microbenchmarks only, and very hard to control.  It kept building
all sorts of unnecessary stuff (like the tests), and unlike
crate2nix it was doing all the builds on only a single machine
instead of using more than one machine.  Worse, for that single
machine it kept picking my laptop instead of my fast servers!  It
seems excessively cargo-flavored for such a straightforward task.

Benchmark: {"hello.outPath":{"kbytes":"244736","system":"0.36","user":"2.76"}}
Benchmark: {"firefox.outPath":{"kbytes":"1506736","system":"2.38","user":"32.01"}}
Benchmark: {"pkgsCross.aarch64-multiplatform.firefox.outPath":{"kbytes":"11334548","system":"10.70","user":"107.07"}}

8018313b68 feat(tvix/glue): add nixpkgs eval benchmark
This adds a criterion.rs-based testbench into tvix-glue.

It can be invoked by running `cargo bench` from inside the `tvix-glue`
crate.
`target/criterion/report/index.html` contains nice graphs.
It's able to diff against the previous run, so you can invoke `cargo
bench` before and after a certain change to reason about the impact in
evaluation performance.

Currently, we need to create a bunch of Evaluator resources inside the
benchmark loop itself, which is a bit annoying, as it leaks into the
things we benchmark.

This should become better with b/262.

Fixes b/322.

9748543f1c chore(tvix): drop sled compression support
It's been a while since the last sled release, and that one binds to a
pretty old version of zstd, requiring workarounds like cl/10090.

Upstream sled main branch currently has zstd halfway patched out (it's
a no-op, but the feature flag and options are still there), and it's in
that state for a year.

Rather than maintaining our own fork of sled, let's just stop using the
compression feature in sled, dropping the version pin to zstd that way,
removing the need for cl/10090.

This doesn't mean we won't reintroduce per-blob compression - but we
probably just won't let sled take care of the compression, but do it
ourselves - which is necessary for more chunked blob storage anyways.

Even though we do drop the feature flag, we still need to explicitly use
use_compression(false).

2b4920c355 fix(tvix/cli): panic on root cause of the fetchurl(non-boot) bug
Currently we produce wrong drvPaths for a large number of packages
that use fetchurl (but not fetchurlBoot, which is what stdenv uses).
A simple reproducer is `pkgs.perl538`.

I debugged this down to the root cause, which is the fact that tvix
doesn't realize that the mapping from FOD-paths to outputHash is
*NOT* a 1:1 mapping.  It is a many-to-one mapping.  You can have
lots of different FODs with the same outputHash or even the same
outPath.  For example, perl538.src and perldevel.src use the same
source tarball but a different `version`.

Anyways, I have found the root cause but have run out of time for a
while, so I've added a panic!() to in the spot where we have a logic
bug in order to call it out.

The only thing this was doing was invoking nix-store --add, which is not
gonna help us populate the tvix-store at all (and we now have
`tvix-store import`).

This is also (rightfully) causing clippy warnings, because of some
fields being unused.

It's more of a skeleton, and rather than shelling out to Nix for some
usecases, we might introduce a "compatible" Nix CLI frontend for a
subset of commands.

Drop this for now, to decrease the noise and confusion.

0e2633048e feat(tvix): run crate2nix generate in CI
This runs `crate2nix generate` in CI and then runs `depotfmt` on the
result to ensure that our machine-generated code is really, really
readable and pretty.  Then it checks that the result of all that
is identical to the committed Cargo.nix.

A self-hashing FOD is used to allow network access.

No magic hashes are involved.

49b34183e3 feat(tvix/eval): rewrite Thunk::force() in nonrecursive form
This commit rewrites Thunk::force() so that it is not (directly)
self-recursive.  It maintains a Vec of all the
previously-encountered thunks which point to the one it is currently
forcing, rather than recursively calling itself.

Benefits:

- Short term:

  This commit saves the cost of a round-trip through the generator
  machinery for the generators::request_force() which is removed by
  this commit.

- Medium term:

  Once a similar transformation has been applied to nix_cmp(),
  nix_add(), nix_eq(), and coerce_to_string(), those four functions,
  along with Thunk::force(), will make non-tail calls only to each
  other.  They can then be merged into a single tail-recursive
  function which does not use the generator machinery at all:

    enum Task { Cmp, Add, Eq, CoerceToString, Force};

    fn Value::walk(task:Task, v1:Value, v2:Value) {
      // ...

- Long term:

  The long-term goal here is to use generators **only for builtins**
  and [Marionette]-style remote control of the VM.  In other words:
  use `async` for things that actually involve concurrency.  Calls
  from the VM to builtins can then be blocking calls, because even
  cppnix will overflow the stack if you make a MAX_STACK_DEPTH-deep
  recursive call which passes through a builtin at every stack frame
  (e.g. `{ func = builtins.sort (a: b: ... func ...) ...}`).

  This way the inner "tight loop" of the interpreter doesn't pay the
  costs of `async` and generators.  These costs manifest in terms
  of: performance, complex nonlocal control flow, and language
  impediments (async Rust is a restricted subset of real Rust, and
  is missing things like traits).

still incorrect (see b/337) but pushes the incorrectness forward a step.

5ffb997864 fix(tvix): ensure PartialOrd/Ord agree for StorePath & NixString
This fixes a *future* clippy lint:
https://rust-lang.github.io/rust-clippy/master/index.html#/incorrect_partial_ord_impl_on_ord_type

In essence, because the implementation of *both* Ord and PartialOrd
implies that ordering is not partial, all results of PartialOrd should
simply be those of Ord. This is to avoid subtle bugs in future
refactorings.

access things like signature verification, or rendering out
(alternations of this) as strings.

be48ba75ab feat(tvix/store/pathinfoservice): implement NixHTTPPathInfoService
NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary
cache protocol provided by Nix binary caches such as cache.nixos.org,
and the Tvix Store Model.
It implements the [PathInfoService] trait in an interesting way: Every
[PathInfoService::get] fetches the .narinfo and referred NAR file,
inserting components into a [BlobService] and [DirectoryService], then
returning a [PathInfo] struct with the root.
Due to this being quite a costly operation, clients are expected to
layer this service with store composition, so they're only ingested
once.
The client is expected to be (indirectly) using the same [BlobService]
and [DirectoryService], so able to fetch referred Directories and Blobs.
[PathInfoService::put] and [PathInfoService::nar] are not implemented
and return an error if called.

This behaves very similar to the nar-bridge-pathinfo code in nar-bridge,
except it's now in Rust.

Also avoid having to traverse inode_data multiple times, by synthesizing
the Arc<…> on our own in the insert case. In that case, the data is
quite small, so cloning it is faster than traversing a second time.

3196fe0143 refactor(tvix): move tvix glue code into glue crate
There's various bits and pieces in tvix-cli that use both the store and
evaluator, as well as nix-compat. For example, builtins.derivation, as
well as the reference scanning implementation.

This "glue code" currently isn't accessible from anywhere else, but it'd
be very useful if it were.

Move it out into a `glue` crate, and make `tvix-cli` a consumer of it.

All the KnownPaths setup and passing around, as well as NIX_PATH
handling is also something that should probably be moved into the glue
crate as well, but that's something left for a future CL.

d91fcd4f28 refactor(tvix/eval): more efficiently intersect attributes
builtins.intersectAttrs is used a _lot_ in nixpkgs eval, for whatever
reason. We previously had a very inefficient implementation that would
allocate for each comparison. It stuck out like a sore thumb in perf
analysis.

This moves to a custom algorithm with two iterators, one for the left
and one for the right side, advancing them along the (borrowed) map
keys until a match is found and allocation is required.

I've not made any effort to reduce the verbosity of this code, I don't
think it's worth it.

On my machine this reduces the mean runtime of evaluating
`nixpkgs.emacs.outPath` by ~8%.

b7ea3d7b32 fix(tvix): fix cargo test for nix_oracle
As described in https://b.tvl.fyi/issues/313, the `nix_oracle` tests
currently fail if run without Nix 2.3 in `$PATH`.

This is not a problem for people running Nix 2.3 on their systems, and
neither is it for the tests running inside Nix derivations itself (as we
hardcode Nix 2.3 there), but for interactive `cargo test` runs, either
using `mg shell //tvix:shell`, or `nix-shell` (from the tvix workspace)
it currently is broken.

Adding Nix 2.3 to the shell fixes that.

1571d7195e fix(tvix/eval/benches): use black_box properly
The purpose of black_box is to actually prevent the compiler from being
able to optimize computation of the benchmarked function away.

To accomplish this, we need to actually *use* black_box to blackbox the
input data away, rather than the return type.

ceca00a866 chore(third_party/crate2nix): apply patches to fix cross
Together with temporarily pointing nixpkgs past
b10994c38c61038970a19fa60bfbec21a61755cc, this now fixes cross-
compilation for tvix.

This incorporates the changes proposed in https://cl.tvl.fyi/9888 and
https://cl.tvl.fyi/9889, but by fixing it in crate2nix, and using the
(re-)generated version of it.

Changes were sent upstream at
https://github.com/nix-community/crate2nix/pull/309,
this pulls in a minimal patch for now.

34fc4637eb refactor(tvix/nix-compat): rename NixHashWithMode -> CAHash
This specific struct is only used to represent content-addressed paths
(in case a Derivation has a fixed-output hash, for example).
Rename `Output`'s `hash_with_mode` to `ca_hash`.

We now also include `CAHash::Text`, and update the `validate` function
of the `Output` struct to reject text hashes there.

This allows cleaning up the various output path calculation functions
inside nix-compat/src/store_path/utils.rs, as they can now match on
the type.

`make_type` is renamed to `make_references_string`,
`build_regular_ca_path` is renamed to `build_ca_path`, and
`build_text_path` has a disclaimer added, because you might not actually
want to use it.

e38733a955 chore(tvix): move castore golang bindings to tvix/castore-go
Have `tvix/castore/protos` only contain the protos, no go noise.

Make the `.pb.go` file generation a pure Nix build
at `//tvix/castore/protos:go-bindings`, and have a script at
`//tvix:castore-go-generate` (TBD) that copies the results to
`tvix/castore-go`.

`//tvix:castore-go`, with sources in `tvix/castore-go` now contains the
tooling around the generated bindings, and the generated bindings
themselves (So go mod replace workflows still work).

An additional CI step is added from there to ensure idempotenty of
the .pb.go files.

The code.tvl.fyi webserver config is updated to the new source code
path. I'm still unsure if we want to also update the go.mod name. While
being a backwards-incompatible change, it'll probbaly make it easier
where to find these files, and the amount of external consumers is still
low enough.

Part of b/323.

0325ae3ba3 fix(tvix/castore): Fix race when ingesting into castore
After finishing the ingestion, the directory putter was not being
closed. This caused a race where the root directory node was accessed
before the directory node had been flushed to the server.

This patch makes it so we close the putter before returning the root
node which should ensure that the root node exists on the directory
service server before the `ingest_path` function returns.

Fixes b/326

Due to the lack of a ATerm parser, we were previously loading the JSON

However, as we now have a ATerm parser, we can load the ATerm
representation directly.
This also means we can test the output path calculation for non-UTF8
Derivations.

specific types.

Also, move the escape_bytes function into there, this is a generic ATerm

98c17147c6 refactor(tvix/nar-bridge): have Export return root node
… and nar size / sha256 digest.

Instead of producing sparse PathInfo messages when NARs are sent to
nar-bridge, the nar-bridge http server now keeps a lookup table
(narsha256) -> (rootNode, narSize)

This removes a whole bunch of noise, because we don't need to keep
sparse fields around.

A convenience function
`GenPathInfo(rootNode *castorev1pb.Node, narInfo *narinfo.NarInfo)` is
added, which is used to produce PathInfo messages, either when receiving
a NAR file over http and uploading it to a remote PathInfoService, or to
synthesize the PathInfoMessage to return to the client, if nar-bridge is
acting as a PathInfoService for a remove Nix HTTP Binary cache.

gen_blobsvc_grpc_client function that provides a gRPC client connected
to a blobservice.

The test is update to use that client to test against, rather than the
server trait, removing the last usage of tonic_mock, so it's removed
as well.

Fixes b/243.

manually waiting for unix sockets to pop up and connect, and creating

Turns out, we also don't actually need to spawn the server in a separate
runtime, it works just fine these days. This might be due to all the
sync barriers in between being gone.

3b620e6d0c refactor(tvix/castore): move gRPC directorysvc tests off tonic_mock
The tests were using the gRPC Service/Server interface, not the gRPC
clients.

Use our new gen_directorysvc_grpc_client() function to spin up a server
in a separate thread, and test via that client, rather than *just* the
server implementation.

This is more correct, because we're now really exercising the gRPC
stack, and some of the stream implementations are also only implemented
on the client.

03fec0b393 refactor(tvix,views/tvix): move shell into separate file
So far, we provided a custom `default.nix` in the root of the tvix josh
workspace, which re-defined the shell attribute from `tvix/default.nix`.
Some of the recent fixes, e.g. the MacOS-specific additions to the list
of dependencies however didn't get ported over to this file, and in
general, it's quite annoying to have two different places for these
things.

Initially I explored the idea of moving this default.nix file to a
default-depot.nix file in the josh worktree only, and then "polyfill"
some of the dependencies, or set up readTree in the josh workspace too,
but it turned out to pull in too many dependencies to be worth
the effort (nix.sparseTree, tools.depotfmt, crate2nix overlay,
third_party.gitignoreSource).

I now took a different approach - moving the definition of the `shell`
attribute from `tvix/default.nix` to its own `shell.nix` file, which is
imported from `tvix/default.nix` in regular depot usecases.

Josh workspace consumers only see the `shell.nix`, which can be used
in a self-contained fashion, the other `default.nix` is gone entirely,
and we update the workspace file to also not show `tvix/default.nix` at
the root either, so running `nix-shell` and then `cargo build` should
still work.

if being built by cargo directly, the feature must be enabled via a

c04041a001 feat(tvix/nar-bridge): add nar-bridge-pathinfo command
This adds an additional nar-bridge-pathinfo command.

It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.

It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.

It's one building component as soon as we have store composition (which
we currently don't, so don't use this).

It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.

It is mostly small type changes and an update to fuse-backend-rs because
upstream currently doesn't work with MacFuse. It also sets the default
FUSE thread count on MacOS to 1 because otherwise the mount command will
hang when shutting down as only one thread gets ENODEV and all the others
just keep blocking.

f8746fcab0 feat(tvix/store): Support listening on UNIX domain sockets
This adds support for listening on UNIX domain sockets via the
tokio-listener crate. The crate will automatically determine whether to
start a TCP or UNIX domain socket server based on the listen address.

Unfortunately, it's not compatible with tonic right out of the box so I
added some wrapper types to implement the necessary traits to make
things work. We should investigate upstreaming a `tonic` option to the
tokio-listener crate which implements the relevant `tonic` traits.

Example:
```
$ tvix-store daemon -l /run/tvix-store.sock
INFO tvix_store: tvix-store listening on /run/tvix-store.sock

$ tvix-store mount -l /mnt/tvix --blob-service-addr grpc+unix:///run/tvix-store.sock --directory-service-addr grpc+unix:///run/tvix-store.sock --path-info-service-addr grpc+unix:///run/tvix-store.sock

242949ecfb fix(tvix/tests/tvix-init): run as pid1, support init=
We were previously not running as PID1, but were executing things via
uinitcmd (by u-root init).
This had some problems - a real system pid1 really wants to be pid1.

u-root init itself seems to be too complicated to configure as a
chainloader, so instead, we just provide init/pid1 ourselves and do the
little bit of mount setup / stage 1 that's necessary.

`tvix.exec` is renamed to `tvix.run`, to further distinguish it from the
`exec` bash function.

Our init will now also power off the machine if the shell, or the custom
tvix.run command finished. In the case of switch_root (`init=` being
passed), we terminate before, so it's up to the real system anyways.

This allows adding the filesystem to a microvm without having to set up
FUSE inside the guest.

e5f2281856 feat(tvix/cli/derivation): reject derivations with empty names
As shown in the previous CLs, we can very well have store paths starting
with periods, but we can't have derivations with an empty name:

```
nix-build -E 'derivation { name = ""; builder = "/bin/sh"; system = "x86_64-linux"; }'
error: store path 'nr7i5pf18hw2zg487vkdyrbasdqylfcj-' has an empty name
```

I'm currently using ErrorKind::Abort here, because we don't have a
Derivation- related error in tvix-eval (and probably don't want to).

32f41458c0 refactor(tvix): move castore into tvix-castore crate
This splits the pure content-addressed layers from tvix-store into a
`castore` crate, and only leaves PathInfo related things, as well as the
CLI entrypoint in the tvix-store crate.

Notable changes:
 - `fixtures` and `utils` had to be moved out of the `test` cfg, so they
   can be imported from tvix-store.
 - Some ad-hoc fixtures in the test were moved to proper fixtures in the
   same step.
 - The protos are now created by a (more static) recipe in the protos/
   directory.

The (now two) golang targets are commented out, as it's not possible to
update them properly in the same CL. This will be done by a followup CL
once this is merged (and whitby deployed)

6b7c936bc5 refactor(tvix/store/fuse): Switch from fuser to fuse-backend-rs
This switches the FUSE implementation from fuser to fuse-backend-rs.
fuse-backend-rs is designed to work with both FUSE and virtiofs.
Virtiofs support will make it possible to plug the tvix-store into a
microvm and have `/nix/store` access without having to setup FUSE inside
the guest.

Additionally fuse-backend-rs has nice support for running multiple FUSE
threads and has some async support.

The goal of this commit is to mechanically switch over to
fuse-backend-rs with minimal changes. I did have to add some locks here
and there because fuse-backend-rs uses `&self` on all methods whereas
fuser uses `&mut self`. `&self` is required for concurrent access to the
FUSE server, so this makes sense.

We can consider switching to concurrent maps and use some other
techniques to reduce lock contention and critical section size.

da6cbb4a45 refactor(tvix/store/blobsvc): make BlobStore async
We previously kept the trait of a BlobService sync.

This however had some annoying consequences:

 - It became more and more complicated to track when we're in a context
   with an async runtime in the context or not, producing bugs like
   https://b.tvl.fyi/issues/304
 - The sync trait shielded away async clients from async worloads,
   requiring manual block_on code inside the gRPC client code, and
   spawn_blocking calls in consumers of the trait, even if they were
   async (like the gRPC server)
 - We had to write our own custom glue code (SyncReadIntoAsyncRead)
   to convert a sync io::Read into a tokio::io::AsyncRead, which already
   existed in tokio internally, but upstream ia hesitant to expose.

This now makes the BlobService trait async (via the async_trait macro,
like we already do in various gRPC parts), and replaces the sync readers
and writers with their async counterparts.

Tests interacting with a BlobService now need to have an async runtime
available, the easiest way for this is to mark the test functions
with the tokio::test macro, allowing us to directly .await in the test
function.

In places where we don't have an async runtime available from context
(like tvix-cli), we can pass one down explicitly.

Now that we don't provide a sync interface anymore, the (sync) FUSE
library now holds a pointer to a tokio runtime handle, and needs to at
least have 2 threads available when talking to a blob service (which is
why some of the tests now use the multi_thread flavor).

The FUSE tests got a bit more verbose, as we couldn't use the
setup_and_mount function accepting a callback anymore. We can hopefully
move some of the test fixture setup to rstest in the future to make this
less repetitive.

84aa07a736 fix(tvix/nar-bridge): Fix directory stack tracking
Previously, nar-bridge, had a couple of bugs with tracking the current
directory when traversing a NAR file.

The included test case looks like:
```
/ (dir)
/test (dir)
/test/tested (file)
/tested (file)
```

Previously, we would do a string prefix match between the current node
and the top of the directory stack to determine if the node is in the
directory. In this case `/test` is a substring of `/tested`; however,
`/tested` is not in the `/test` directory. The fix is to append a `/` to
the directory name when doing the prefix match, so `/test/` is not a
prefix of `/tested`.

Additionally, when popping the stack, we need to continuously pop the
stack until the new node is in the directory at the top of the stack
(stopping before we pop the root directory)

Example:
```
/ (dir)
/a (dir)
/a/b (dir)
/a/b/c (file)
/z (file)
```

Previously, `z` would end up in directory `/a` because we only the pop
the stack once.

The included test case requires both of these issues to be fixed for it
to pass, so I think it is sufficient.

51b8571c48 feat(tvix/store): improve error message formatting
WrongSorting(Vec<u8>) actually encodes the name of a node, so if we can,
we want this to display it as a string (and fall back to the base64
encoding if we can't).

Before:

> rpc error: code = InvalidArgument desc = directory b3:yfwNlpPm8MkrRvshGHfgMtKLoSDtX2pKliVuVWmUt5g= failed validation: [108, 111, 99, 97, 108, 101] is not sorted

After:

> rpc error: code = InvalidArgument desc = directory b3:yfwNlpPm8MkrRvshGHfgMtKLoSDtX2pKliVuVWmUt5g= failed validation: locale is not sorted

Included changes:

* tvix/eval: enable some lang tests on nix_latest

  Nix 2.16 contains some breaking language changes which Tvix does
  not yet implement, but the existing tests for them are now passed by
  Nix 2.16 (but not yet by Tvix).

* tvix/eval: disable a lang test on nix_latest

  In Nix 2.17, the identifier formatting test fails because some
  behaviour changed. We have not investigated further yet.

* 3p/overlays: use version of ihp-hsx that works with GHC 9.4

  Originally from the separate cl/9185.

* top-level: introduce a mechanism to exclude build targets from CI in
  the top level. This fixes b/296.

* users/grfn: disable builds of xanthous (and dependents) until the
  CLs fixing its build are submitted

* 3p/overlays: build nixos-option against Nix 2.15, the only version
  with which it builds

* 3p/overlays: bump tdlib to 1.8.16

mountpoint`), the future is waiting for the signal is never resolved and
the task is stopped.

3c340b28bd refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crate
This trait is eval-specific, there's no point in dealing with these
things in tvix-store.

This implements the EvalIO interface for a Tvix store.
The proper place for this glue code (for now) is tvix-cli, which knows
about both tvix-store and tvix-eval.

There's one annoyance with this move: The `tvix-store import` subcommand
previously also used the TvixStoreIO implementation (because it
conveniently did what we wanted).
Some of this code had to be duplicated, mostly logic to calculate the
NAR-based output path and create the PathInfo object.

Some, but potentially more of this can be extracted into helper
functions in a shared crate, and then be used from both TvixStoreIO in
tvix-cli as well as the tvix-store CLI entrypoint.

0193f07642 refactor(tvix/nix-compat/nixhash): validate digest lengths
There was a NixHash::new() before, which didn't perform any validation
of the digest length. We had some length validation when parsing nix
hashes or SRI hashes, but some places didn't perform validation and/or
constructed the struct directly.

Replace NixHash::new() with a
`impl TryFrom<(HashAlgo, Vec<u8>)> for NixHash`,  which does do this
validation, and update constructing code to use that, rather than
populating structs directly. In some rare cases where we're sure the
digest length is correct we still populate the struct manually.

Fixes b/291.

d504b440c2 feat(tvix/nix-compat): don't swallow hash validation errors
Previously, Output deserialization would silence validation errors and
provide `None` for `hash_with_mode` as soon as a validation error would
happen inside of the `NixHashWithMode` deserialization, e.g. invalid
hash length would not provide an validation error but a silent `None`
value.

This is problematic, we workaround a serde limitation here by writing
our own Deserializer.

As you can see, we write some boilerplate code unfortunately, as, for
example:

- `#[serde(fail_if_unparsed_as="Option::is_none")]` is not a thing,
  otherwise, we could have been able to just bubble up errors in case of
  "not fully parsed" (and not missing) values.

- `From<&serde_json::Value> for serde:🇩🇪:Unexpected` is not a thing,
  otherwise, we could just map invalid type errors and reuse the
  existing types instead of doing extremely bizarre things with
  `serde:🇩🇪:Unexpected::Other`, note: this is a not problem for
  expected, we know what we expect, we don't know what we received in
  practice.

I decided to write a `NixHashWithMode::from_map` which will eat a map
deserialized via `serde_json`, so our serde magic is not totally "data
model" agnostic.

I wanted to go for data model agnosticity and enable maximal
performance, e.g. building the structure as the map values are streamed
in the Visitor, this is needlessly painful because `Output` and
`NixHashWithMode` are in different files and this really makes sense
only if we write the full implementation in one file, indeed, otherwise,
you end up duplicating the work or having strange coupling.

So, for now, we will allocate a full map of the fields inside the
`Output`, i.e. if any "unknown field" is in that map, we will
deserialize it for no reason.

Doing it properly, as I repeat it in the code and to flokli at C3Camp
2023, requires to patch serde upstream IMHO.

72e82ffcb1 refactor(tvix/store): use bytes for node names and symlink targets
Some paths might use names that are not valid UTF-8. We should be able
to represent them.

We don't actually need to touch the PathInfo structures, as they need to
represent StorePaths, which come with their own harder restrictions,
which can't encode non-UTF8 data.

While this doesn't change any of the wire format of the gRPC messages,
it does however change the interface of tvix_eval::EvalIO - its
read_dir() method does now return a list of Vec<u8>, rather than
SmolStr. Maybe this should be OsString instead?

638f3e874d feat(tvix/store/fuse): implement open explicitly
This "reverts" commit 9f600de226 (the
initial revert of f5e291cf83).

Now with BlobService returning a BlobReader that implements io::Seek, we
can actually just call blob_reader.seek(io::SeekFrom::Start(offset as
u64)).

This means, we currently will fail to seek backwards inside a file.

Once the gRPC protocol gets support for offsets and verified streaming,

42dc18353d feat(tvix/nix-compat): have StorePath accept bytes
The primary constructor for this is now from_bytes, from_string is
simply calling .as_bytes() on the string, passing it along.

The InvalidName error now contains a Vec<u8>, to encode the invalid name
(which might not be a string anymore).

from_absolute_path now accepts a &[u8] (even though we might want to
make this a OSString of some sort).

StorePath::validate_name has been degraded to a pub(crate) function.
It's still used in src/derivation, even though it probably shouldn't at
all - that cleanup is left for cl/8412 though.

8adc9c56f2 docs(tvix): document when pointer equality is preserved in C++ Nix
This explicitly documents behavior of C++ Nix that goes against the
intuition you'd gather from this document: that e.g. a simple select
from an attribute set causes a value to no longer be pointer equal to
its former self.

The point of documenting this is that we can show in a to be written
section on the use of pointer equality in nixpkgs that pointer equality
is only needed in a limited sense for evaluating it (C++ Nix's exterior
pointer equality). Tvix's pointer equality is far more powerful since
value identity preserving operations also preserve pointer equality,
generally speaking (this is because we implement interior pointer
equality in my made up terminology). This should eventually also be
documented.

4ba624efae fix(tvix/eval): use byte, not codepoint index for slicing in escape
This fixes a subtle issue which would occasionally lead to a crash (e.g.
when evaluating (pkgs.systemd.outPath with --trace-runtime): With each
character in the string that has a multi byte representation in UTF-8,
the actual byte position and what tvix thought it was would get out of
sync. This could either lead to

* Tvix swallowing characters or jumbling characters if multi byte
  characters would cause the tracked index to become out of sync with
  the byte position before the first character to be escaped, or

* Tvix crashing if (in the same situation) the out of sync index would
  be within a UTF-8 byte sequence.

Luckily, std's `char_indices()` iterator implements exactly what
`nix_escape_char()`'s original author had in mind with
`.chars().enumerate()`. Using `i + 1` for continuing is safe, since all
characters that need (in fact, can) to be escaped in Nix are represented
as a single byte in UTF-8.

864931b297 docs(tvix): start restructuring pointer equality document
I want to expand on the C++ Nix behavior, since it seems relevant to
note that a lot of operations in C++ Nix (like select) don't preserve
pointer equality (see
<https://github.com/NixOS/nix/issues/3371#issuecomment-1596167957>).
It is especially so, as Tvix establishes pointer equality in a different
way and thus shows differing behavior. Therefore I want to additionally
document Tvix's current behavior and make it more explicit to what
extent nixpkgs needs pointer equality.

66047063e0 fix(tvix/eval): use realpaths for import cache
I've noticed this behavior when writing the admittedly cursed test case
included in this CL. Alternatively we could use some sort of machinery
using `builtins.trace`, but I don't think we capture stderr anywhere.

I've elected to put this into the eval cache itself while C++ Nix does
it in builtins.import already, namely via `realisePath`. We don't have
an equivalent for this yet, since we don't support any kind of IfD, but
we could revise that later. In any case, it seems good to encapsulate
`ImportCache` in this way, as it'll also allow using file hashes as
identifiers, for example.

C++ Nix also does our equivalent of canon_path in `builtins.import`
which we still don't, but I suspect it hardly makes a difference.

b25d98a84e feat(tvix/store/fuse): initial implementation
This is a first implementation of a FUSE filesystem, mounting tvix-store
to a given location.

This is mostly meant as one additional lens into a store, and could be
used for builds. It's not meant to be used as a general-purpose thing.

It still has some rough edges:

 - It doesn't implement open/close, so it doesn't use file handles.
   Which means, we need to open blobs for partial reads over and over
   again.
 - It doesn't implement seek, as BlobReader doesn't implement seek yet.
 - It doesn't track "lifetimes" of inodes by listening on forget,
   meaning it might hold more data in memory than necessary.
 - As we don't have store composition (and a caching layer) yet,
   operations might be slow.

4516cd09c5 fix(tvix/eval): only finalise formal arguments if defaulting
When dealing with a formal argument in a function argument pattern that
has a default expression, there are two different things that can happen
at runtime: Either we select its value from the passed attribute
successfully or we need to use the default expression. Both of these may
be thunks and both of these may need finalisers. However, in the former
case this is taken care of elsewhere, the value will always be finalised
already if necessary. In the latter case we may need to finalise the
thunk resulting from the default expression. However, the thunk
corresponding to the expression may never end up in the local's stack
slot. Since finalisation goes by stack slot (and not constants), we need
to prevent a case where we don't fall back to the default expression,
but finalise anyways.

Previously, we worked around this by making `OpFinalise` ignore
non-thunks. Since finalisation of already evaluated thunks still
crashed, the faulty compilation of function pattern arguments could
still cause a crash.

As a new approach, we reinstate the old behavior of `OpFinalise` to
crash whenever encountering something that is either not a thunk or
doesn't need finalisation. This can also help catching (similar)
miscompilations in the future. To then prevent the crash, we need to
track whether we have fallen back or not at runtime. This is done using
an additional phantom on the stack that holds a new `FinaliseRequest`
value. When it comes to finalisation we check this value and
conditionally execute `OpFinalise` based on its value.

Resolves b/261 and b/265 (partially).

0f71d8f813 test(tvix/eval): genericClosure (pointer) comparison support
genericClosure has very limited support for pointer equality: It relies
on comparison (not equality!) in C++ Nix, so as soon as C++ Nix supports
comparing lists (langVersion >= 6) we can rely on pointer equality for
key.

Since Tvix uses equality, not comparison for the insert, our behavior is
currently different, as documented by the notyetpassing tests.

0005737f11 fix(tvix/eval): make tvix display values like nix-instantiate(1)
In order for the test suite we have currently to be comparable to C++
Nix, we need to display values in the same way. This was largely the
case except in some weird cases.

* <CODE> for thunks and <CYCLE> for repeated thunks (?) are already in
  use. <CODE> formatting is tested by the oracle test suite already.

* Instead of lambda, we need to use <LAMBDA>

* <<primop>> and <<primop-app>> (a formatting C++ Nix uses nowhere)
  now are <PRIMOP> and <PRIMOP-APP>.

We'll probably want to have a fancier display of values (in a separate
trait) down the line. This could be used for interactive usage, e.g. the
REPL or a potential debugger.

There is a peculiarity with C++ Nix 2.3 formatting primops: import is
considered a <<PRIMOP-APP>>, since it is internally implemented by means
of scopedImport. This implementation detail no longer leaks in C++ Nix
2.13 nor in Tvix.

<CYCLE> display is untested at the moment, since we exhibit a
discrepancy to C++ Nix 2.3. Our current detection is more similar to C++
Nix 2.13—luckily it is also the more consistent of the two. See also
b/245.

c5851fb815 refactor(tvix/store/blobsvc): make from_addr not async
A previous iteration of this code did actually connect (in the gRPC
client), which was why we had this function async.

However, as the connection there is now lazy too, we can drop the
asyncness in this function.

8e5551329a fix(tvix/eval): don't thunk home relative paths
C++ Nix resolves home relative paths at [parse] time. This is not an
option for us, since it prevents being able to separate the compilation
and execution phase later (e.g. precompiled nix expressions). However, a
practical consequence of this is that paths expressions are always
literals (strict) and never thunks.

compile() without much of a care and trust that it will sort it out
correctly.

If function formals blow up as a result of this, it likely indicates
that the expression is treated incorrectly by compile(), not
compile_param_pattern().

10c6cb7251 fix(tvix/eval): type check function argument with set pattern
C++ Nix forces and typechecks the passed argument even if it is not
necessary in order to compute the return value of the function. I
discovered this when I thought our formals miscompilation might be that
we are too strict, but doesn't look like it in this case.

This now creates different store client, depending on the cli

The `import` command will connect to the gRPC service, and the `daemon`
command will use the sled implementation.

It might make sense to define some URI syntax to make this configurable
by the user, via the CLI.

considered adding this capability to the tvix_tests/nix_tests

scheme to do it in a clean way, I've postponed it–it's nice that our
tests are compatible with C++ Nix's test suite.

385c797884 fix(tvix/eval): thunk unary operator applications
Unary operator applications are thunked which can easily be observed by

  nix-instantiate --eval -E '[ (!true) (-1) ]'

Unfortunately, there are few simple expressions where this makes a
difference in the end result. Thus it only cropped up when using nixpkgs
for cross compilation: Here we would compile the expression

  !(stdenv.cc.isGNU or false)

to assemble python3Minimal's passthru attribute set (at least this seems
to be the most likely explanation from the backtraces I've studied).
This means that an unthunked

    <stdenv.cc.isGNU or false>
    OpForce
    OpInvert

would be performed in order to assemble this attribute set, causing
stdenv.cc to be evaluated too early, causing an infinite recursion.

Resolves b/273.

It seems that having a test suite that doesn't use --strict and relies
on thunks rendered as <CODE> would be beneficial for catching such
issues. I've not been able to find a test case with --strict that
demonstrates the problem fixed in this CL.

3b33c19a9c fix(tvix): don't call function eagerly in genList, map & mapAttrs
mapAttrs, map and genList call Nix functions provided by the caller and
store the result of applying them in a Nix data structure that does not
force all of its contents when forced itself. This means that when such
a builtin application is forced, the Nix function calls performed by the
builtin should not be forced: They may be forced later, but it is also
possible that they will never be forced, e.g. in

    builtins.length (builtins.map (builtins.add 2) [ 1 2 3 ])

it is not necessary to compute a single application of builtins.add.

Since request_call_with immediately performs the function call
requested, Tvix would compute function applications unnecessarily before
this change. Because this was not followed by a request_force, the
impact of this was relatively low in Nix code (most functions return a
new thunk after being applied), but it was enough to cause a lot of
bogus builtins.trace applications when evaluating anything from
`lib.modules`. The newly added test includes many cases where Tvix
previously incorrectly applied a builtin, breaking a working expression.

To fix this we add a new helper to construct a Thunk performing a
function application at runtime from a function and argument given as
`Value`s. This mimics the compiler's compile_apply(), but does itself
not require a compiler, since the necessary Lambda can be constructed
independently.

I also looked into other builtins that call a Nix function to verify
that they don't exhibit such a problem:

- Many builtins immediately use the resulting value in a way that makes
  it necessary to compute all the function calls they do as soon as
  the outer builtin application is forced:

  * all
  * any
  * filter
  * groupBy
  * partition

- concatMap needs to (shallowly) force the returned list for
  concatenation.

- foldl' is strict in the application of `op` (I added a comment that
  makes this explicit).

- genericClosure needs to (shallowly) force the resulting list and some
  keys of the attribute sets inside.

Resolves b/272.

5d3fb33baa feat(tvix/eval): implement unthunking in compiler
This feature allows the compiler to detect situations where the
created thunk is useless and can be merged into the parent chunk
instead.

The only case where the compiler does this initially is when
statically optimising a select expression.

For example, previously the expression `builtins.length` compiled into
two thunks:

1. An "inner" thunk which contained an `OpConstant` that had the
   optimised `length` builtin in it.

2. An "outer" thunk which contained an `OpConstant` to access the
   inner thunk, and the trailing OpForce of the top-level program.

With this change, the inner thunk is skipped completely and the outer
chunk directly contains the `length` builtin access.

This can be applied in several situations, some easier than others,
and we will add them in as we go along.
