5a97888d8b chore(tvix): Migrate members to inherit deps from workspace
From now on we will add the dependencies and their version in the root
Cargo.toml and in order to enable the dependency for a workspace member
we set `workspace = true` in the member's Cargo.toml.

a5fcfd80a1 fix(tvix/nix-compat-derive): Get rid of external feature flag
The external feature flag was there because I couldn't find a way to
refer to crate and nix-compat with the same name so that the generated
code could be the same.

In essence `use nix_compat::nix_daemon:🇩🇪:NixDeserialize` is an error
when used inside nix_compat crate.

So my best fix was the external feature flag until I found the solution
used here which also removes the flag completely.

2fa5e71d5e fix(tvix/store): restore v1alpha reflection endpoint
tonic-reflection 0.12.x moved from the v1alpha to v1 of the reflection
protocol.

However, most clients, like Postman, Kreya and evans don't support that
one yet.

Bump tonic-reflection to 0.12.2, which re-introduces v1alpha support
alongside the v1 version of it, registering both services.

This fixes the example documented in tvix/store/README.md, it was
previously failing as evans couldn't find the v1alpha reflection
service.

See https://github.com/hyperium/tonic/pull/1888 for details.

Add a trait for deserializing a type from a daemon worker connection.
This adds the NixDeserialize trait which is kind of like the serde
Deserialize trait in that individual types are meant to implement it

The NixDeserialize trait takes something that implements NixRead as
input so that you can among other things mock the reader.

e03ea11bad feat(nix-compat/nix_http): init parse_nar[info]_str
This moves the URL component parsing code we had in nar-bridge to
nix-compat.

We change the function signature to return an Option, not a
Result<_, StatusCode>.

This allows returning more appropriate error codes, as we can
ok_or(…) at the callsite, which we now do: on an upload to an
invalid path, we now return "unauthorized", while on a GET/HEAD, we
return "not found".

This also adds support to parse compression suffixes. While not
supported in nar-bridge, other users of nix-compat might very well want
to parse these paths.

Also fix the error message when parsing NAR urls, it mentioned 32, not
52, which is a copypasta error from the narinfo URL parsing code.

a259613c76 feat(nix-compat/narinfo/signature): generalize name field
Requiring `name` to be a `&str` means it'll get annoying to pass around
`Signature`, but being able to pass them around in an owned fashion is
kinda a requirement for a stronger typed `PathInfo` struct, where we
want to have full ownership.

Rework the `Signature` struct to become generic over the type of the
`name` field. This means, it becomes possible to have owned versions
of it.

We don't want to impose `String` or `SmolStr` for example, but want to
leave it up to the nix-compat user to decide.

Provide a type alias for the existing `&str` variant (`SignatureRef`),
and use it where we previously used the non-generic `Signature` one.

Add some tests to ensure it's possible to *use* `Signature` with both
`String` and `SmolStr` (but only pull in `smol_str` as dev dependency
for the tests).

Also, add some more docstrings, these were a bit sparse.

d6c57eb957 refactor(tvix/eval): ensure VM operations fit in a single byte
This replaces the OpCode enum with a new Op enum which is guaranteed to fit in a
single byte. Instead of carrying enum variants with data, every variant that has
runtime data encodes it into the `Vec<u8>` that a `Chunk` now carries.

This has several advantages:

* Less stack space is required at runtime, and fewer allocations are required
  while compiling.
* The OpCode doesn't need to carry "weird" special-cased data variants anymore.
* It is faster (albeit, not by much). On my laptop, results consistently look
  approximately like this:

  Benchmark 1: ./before -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings
  Time (mean ± σ):      8.224 s ±  0.272 s    [User: 7.149 s, System: 0.688 s]
  Range (min … max):    7.759 s …  8.583 s    10 runs

  Benchmark 2: ./after -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings
  Time (mean ± σ):      8.000 s ±  0.198 s    [User: 7.036 s, System: 0.633 s]
  Range (min … max):    7.718 s …  8.334 s    10 runs

  See notes below for why the performance impact might be less than expected.
* It is faster while at the same time dropping some optimisations we previously
  performed.

This has several disadvantages:

* The code is closer to how one would write it in C or Go.
* Bit shifting!
* There is (for now) slightly more code than before.

On performance I have the following thoughts at the moment:

In order to prepare for adding GC, there's a couple of places in Tvix where I'd
like to fence off certain kinds of complexity (such as mutating bytecode, which,
for various reaons, also has to be part of data that is subject to GC). With
this change, we can drop optimisations like retroactively modifying existing
bytecode and *still* achieve better performance than before.

I believe that this is currently worth it to pave the way for changes that are
more significant for performance.

In general this also opens other avenues of optimisation: For example, we can
profile which argument sizes actually exist and remove the copy overhead of
varint decoding (which does show up in profiles) by using more adequately sized
types for, e.g., constant indices.

Known regressions:

* Op::Constant is no longer printing its values in disassembly (this can be
  fixed, I just didn't get around to it, will do separately).

3cd57ce4e3 feat(tvix/glue): Add refscanner pattern and AsyncRead
This splits the existing ReferenceScanner into a ReferenceScanner and
ReferencePattern as well as adds an AsyncRead implementation that can
do a scan while you read from it.

The reason to split the scanner in two is that generating the pattern
is expensive and when ingesting build results with multiple outputs you
want to do several independant scans that look for the same pattern.

The reader is for scanning files without having to load the entire file
into memory.

d378111d77 feat(tvix/eval): Store hash in key of interner
Rather than storing the leaked allocation for the string as the key in
the interner, store the hash (using NoHashHashBuilder). I thought this
would improve performance, but it doesn't:

hello outpath           time:   [736.85 ms 748.42 ms 760.42 ms]
                        change: [-2.0754% +0.4798% +2.7096%] (p = 0.72 > 0.05)
                        No change in performance detected.

but it at least doesn't *hurt* performance, and it *does* avoid an
`unsafe`, so it's probably net good.

59056cf705 feat(tvix/eval): Leak strings (with flag to disable)
Default to always leaking strings, and copying strings by copying
pointers rather than cloning the underlying allocation. This (somewhat
bafflingly) doesn't seem to affect any benchmarks, but paves the way for
some tricks around string allocation that do.

Unfortunately, we can't do this (yet?) for contextful strings, for
reasons I don't currently understand but which I will address later,
when I address contextful strings more holistically.

I've left a flag in here to disable this, both to test the cloning logic
for strings for when/if we decide to bring this back, and to allow
people who care more about memory usage than perf to disable leaking.

This adds an implementation of nar-bridge in Rust.
Currently, only the GET parts are implemented.

Contrary to the Go variant, this doesn't try to keep a mapping from nar
hashes to root node in memory, it simply encodes the root node itself
(stripped by its basename) into the URL.

This pulls in a more recent version of axum than what we use in
tonic, causing two versions of http and hyper, however dealing with
`Body::from_stream` in axum 0.6 is much more annoying, and
https://github.com/hyperium/tonic/pull/1740 suggests this will be fixed

0ad986169d test(tvix/cli): Make the REPL testable
Juggle around the internals of the tvix-cli crate so that we expose the
Repl as a public type with a `send` method, that sends a string to the
repl and *captures all output* so that it can be subsequently asserted
on in tests. Then, demonstrate that this works with a single (for now)
REPL test using expect-test to assert on the output of a single command
sent to the REPL.

As the REPL gets more complicated, this will allow us to make tests that
cover that complex behavior.

fc63594631 feat(tvix/repl): Allow binding variables at the top-level
Allow binding variables at the REPL's toplevel in the same way the Nix
REPL does, using the syntax <ident> = <expr>. This fully, strictly
evaluates the value and sets it in the repl's "env", which gets passed
in at the toplevel when evaluating expressions.

The laziness behavior differs from Nix's, but I think this is good:

    ❯ nix repl
    Welcome to Nix version 2.3.18. Type :? for help.

    nix-repl> x = builtins.trace "x" 1

    nix-repl> x
    trace: x
    1

    nix-repl> x
    1

vs tvix:

    tvix-repl> x = builtins.trace "x" 1
    trace: "x" :: string
    tvix-repl> x
    => 1 :: int
    tvix-repl> x
    => 1 :: int

618aacaa61 feat(tvix/tracing): http trace propagation
Introduces a helper function within tvix-tracing that returns a reqwest
tracing middleware that will ingest the traceparent if otlp is enabled.

It is feature flagged in tvix-tracing so not every consumer of that
library automatically has reqwest in its dependencies.

Tested using netcat to verify that the `traceparent` header is there if
otlp is enabled and missing if otlp feature is disabled.

639a00e2ab feat(tvix/tracing): gRPC trace context propagation
This introduces optional helper function in tvix/tracing for trace
propagation and uses these helper in the `tvix-store`.

The GRPCBlobService, GRPCDirectoryService and GRPCPathInfoService now
accept a generic client, meaning the client can be generated with either
`::new` or `::with_interceptor`.

This was tested and validated by starting a `tvix-store daemon` and
`tvix-store import`.

28b692fd50 feat(tvix/tvix-store): improve progress bars
Don't show an empty spinner for daemon commands.
Move the bar to the right, so the text is better aligned between spinner
progress and bar progress styles.

Generally, push progress bars a bit more down to the place where we can
track progress. This includes adding one in the upload_blob span.

Introduce another progress style template for transfers, which
interprets the counter as bytes (not just a plain integer), and also a data rate.
Use it for here and in the fetching code, and also make the progress bar
itself a bit less wide.

7e42b4f314 fix(tvix/store/bin): fix shutdown behaviour for FUSE
Both umounts happening from another process, as well as tvix-store
itself calling umount() on FuseDaemon will cause the FUSE worker threads
to terminate.

So far there was no nice way to wait on these threads to be terminated
from multiple places, causing the `tvix-store mount` command to only be
terminated if interrupted via ctrl-c, not via an external umount.

Update FuseDaemon to use a ThreadPool, which gives us a join primitive
over all threads, that can also be called from multiple places.

Await on a join() from there to end the program, not the ctrl-c signal
handler as it was before.

Using FuseDaemon from multiple tasks requires Arc<>-ing both the
ThreadPool as well as the inner FuseSession (which also needs to be
inside a Mutex if we want to unmount), but now we can clone FuseDaemon
around and use it in two places. We could probably also have used an
Option and drop the FuseSession after the first umount, but this looks
cleaner.

I had to be a bit tricky with the combinatorial complexity when adding
this, but the resulting code still seems manageable.

fa7ed39bf4 feat(tvix/tracing): correctly close otlp on exit
Provide a new interface for forcing a flush of otlp traces and use this
interface to shutdown otlp prior to exiting tvix-store, either if the
tool was stopped with a SIGTERM or ended regularly.
This also fixes an issue where traces were not even exported if for
example we just imported 10 paths and never even emitted more than 256
traces. The implementation uses a mpsc channel so a flush can be done
without having to wait for it to complete. If you want to wait for a
flush to complete you can provide a oneshot channel which will receive a
message once flushing is complete.

Because of a otlp bug `force_flush` as well as
`shutdown_tracer_provider` need to be executed using `spawn_blocking`
otherwise the function will deadlock. See
https://github.com/open-telemetry/opentelemetry-rust/issues/1395#issuecomment-1953280335
