9cd2e92065 refactor(tvix/store/fs): mv sparse -> populated directories
Do this upgrade whenever someone is actually interested in the children
of a directory, but that directory doesn't contain a more detailed
listing. This is much more predictable, and removes a bunch of confusing
code from the inode tracker itself.

a778b855d2 refactor(tvix/store/fs): simplify name_in_root_to_ino_and_data
Have it return libc::ENOENT errors rather than an Option<…>.

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.

2405399580 refactor(tvix/src/fs): reduce write lock, avoid inode_tracker lookup
Code after this big match block only cares about parent_digest and
children, so there's no need to do another inode_tracker.get in there.

This also allows removing another if let block, right after, as we don't
need to destructure parent_data anymore.

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

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.

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.

c847cc32d9 refactor(tvix/castore): move tests to grpc client, rm tonic-mock
Similar to gen_directorysvc_grpc_client, introduce a
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
temporary directoires to create the unix sockets in.

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
cargo flag.

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.

cfb810d81a fix(tvix/store): Fix FUSE support on MacOS

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.

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.

3816eaa5e9 feat(tvix/store): add simple integration test
This imports the docs folder into the tvix store, and ensures it comes
up with the same store path as Nix.

While we validate hashes in general through tvix-cli output path checks
already, it doesn't include the tvix-store CLI itself.

110328232d chore(3p/sources): bump channels & overlays (2023-08-21)
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

This enables the tokio `signal` feature, and registers a ctrl_c signal
handler, which will use the unmount handle to unmount in case a ctrl-c

This avoids having disconnected mountpoints when Ctrl-C'ing a

In case the filesystem is unmounted externally (via `umount /path/to/
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.

a6580748aa feat(tvix/store/digests): use bytes::Bytes instead of Vec<u8>
This will save us some copies, because a clone will simply create an

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.

7613e2e769 feat(tvix/store/blobservice): implement seek
For memory and sled, it's trivial, as we already have a Cursor<Vec<u8>>.
For gRPC, we simply reject going backwards, and skip n bytes for now.

Once the gRPC protocol gets support for offsets and verified streaming,
this can be improved.

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.

A previous iteration of this code did actually connect (in the gRPC

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.

a2303da01f fix(tvix/eval): use normal thunking behavior for default in formals
When comparing to C++ Nix, we notice that the thunking of default
expressions in function formals corresponds to their normal thunking,
e.g. literals are not thunked. This means that we can just invoke
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

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.

nixpkgs eval tests might be fine (and fast!) with a purely in-memory
backend, but other usages might involve talking to a local tvix-store
over gRPC (using the gRPC client, either unix domain socket or even
further away remote), or running tvix-store in "embedded" mode (using
another client than the gRPC client).

It also implements display, which will print the base64 representation.
This should reduce some boilerplate when parsing Vec<u8>.

616fa4476f refactor(tvix/store): remove ChunkService
Whether chunking is involved or not, is an implementation detail of each
Blobstore. Consumers of a whole blob shouldn't need to worry about that.
It currently is not visible in the gRPC interface either. It
shouldn't bleed into everything.

Let the BlobService trait provide `open_read` and `open_write` methods,
which return handles providing io::Read or io::Write, and leave the
details up to the implementation.

This means, our custom BlobReader module can go away, and all the
chunking bits in there, too.

In the future, we might still want to add more chunking-aware syncing,
but as a syncing strategy some stores can expose, not as a fundamental
protocol component.

This currently needs "SyncReadIntoAsyncRead", taken and vendored in from
https://github.com/tokio-rs/tokio/pull/5669.
It provides a AsyncRead for a sync Read, which is necessary to connect
our (sync) BlobReader interface to a GRPC server implementation.

As an alternative, we could also make the BlobReader itself async, and
let consumers of the trait (EvalIO) deal with the async-ness, but this
is less of a change for now.

In terms of vendoring, I initially tried to move our tokio crate to
these commits, but ended up in version incompatibilities, so let's
vendor it in for now.

We already returned UnexpectedEof in case the reader stopped returning
bytes too early, but similarly we should also fail if there's still
bytes left to be read in the reader passed.

We normally use the NAR writer to produce new NAR files, so the readers
point to the blobs we actually want to render, and having some data left
in there should be an error.

If for some reason the reader points to more data than just the blob,
the `.take` method can be used to limit it to the (known) size.

Now, we have roughly the same "safe-ish" ways of constructing them as
C++ Nix, and only those are exposed:

- Make text hashed content-addressed store paths

- Make other content-addressed store paths

- Make input-addressed fixed output hashes

ce502bdc89 refactor(tvix/eval): improve representation of chunk/span mapping
This switches out the previous compressed representation (count of
instructions per span) with a representation where the chunk's span
list stores the index of the first operation that belongs to a span,
and finds the right span by using a binary search when looking them
up.

This improves the lookup complexity from O(n) to O(log n).

This improvement was suggested and (mostly) implemented by GPT-4. I
only fixed up some names and updated the logic for deleting
spans (which it only did not do because I didn't tell it about that).

The code was verified by producing a complex error before/after the
change and ensuring that all spans in the error match exactly.

5f2c2e79e1 refactor(tvix/nix-compat): move build_store_path out of derivation
This doesn't have anything to do with ATerms, we just happen to be using
the aterm representation of a Derivation as contents.

Moving this into store_path/utils.rs makes these things much cleaner -
Have a build_store_path_from_references function, and a
build_store_path_from_fingerprint helper function that makes use of it.

build_store_path_from_references is invoked from the derivation module
which can be used to calculate the derivation path.

As we need to also add the `.drv` suffix to the name we pass into
text_hash_string inside calculate_derivation_path, we can simply add the
suffix there and drop the parameter from build_store_path.

367a5e9922 feat(tvix/store/directorysvc): add gRPC client
This provides a GRPCDirectoryService struct implementing
DirectoryService, allowing a client to Directory objects from a (remote)
tvix-store.

Remote in this case is anything outside the current process, be it
another process, or an endpoint on the network.

To keep the sync interface in the `DirectoryService` trait, a handle to
some tokio runtime needs to be passed into the constructor, and the two
methods use `self.tokio_handle.spawn` to start an async function, and
`self.tokio_handle.block_on` to wait for its completion.

The client handle, called `grpc_client` itself is easy to clone, and
treats concurrent requests internally. This means, even though we keep
the `DirectoryService` trait sync, there's nothing preventing it from
being used concurrently, let's say from multiple threads.

There's still two limitations for now:

1) The trait doesn't make use of the `recursive` request, which
   currently leads to a N+1 query problem. This can be fixed
   by `GRPCDirectoryService` having a reference to another
   `DirectoryService` acting as the local side.
   I want to wait for general store composition code to pop up before
   manually coding this here.

2) It's currently only possible to put() leaf directory nodes, as the
   request normally requires uploading a whole closure. We might want
   to add another batch function to upload a whole closure, and/or do
   this batching in certain cases. This still needs some more thinking.

80aaadfc19 fix(tvix/eval): use span of set for OpForce in attribute access
Emits the span of the `set` that is being accessed in the `force`
operation of an attribute access.

Looking at traces, it's a lot more useful to get information about
*what* is being forced, as in cases like `foo.bar` it can be
misleading to have an error highlight `bar`, when the error occured
while forcing `foo` to be able to access `bar` in the first place.

This reports the span

1. of the code within a thunk,
2. of the place where the thunk was instantiated,
3. of the place where the thunk was first forced,
4. of the place where the thunk was forced again,

when yielding an infinite recursion error, which hopefully makes it
easier to debug them.

The spans are tracked in the ThunkRepr::Blackhole variant when putting
a thunk under evaluation.

Note that we currently have some loss of span precision in the VM loop
when switching between frame types, so spans 3/4 are currently a bit
wonky. Working on it.

`NativeError` and `BytecodeError` error kinds (which just wrap inner
errors) to create a set of diagnostics to emit.

be coloured red in terminals), the other ones will be emitted with
`note` type, highlighting the causal chain.

Example:
https://gist.github.com/tazjin/25feba7d211702453c9ebd5f8fd378e4

This is currently quite verbose, and we can cut down on this further,

b55d1f97ce refactor(tvix/nix-compat): -derivation::Hash, +NixHash
This stops using our own custom Hash structure, which was mostly only
used because we had to parse the JSON representation somehow.

Since cl/8217, there's a `NixHash` struct, which is better suited to
hold this data. Converting the format requires a bit of serde labor
though, but that only really matters when interacting with JSON
representations (which we mostly don't).

36bed4ce57 chore(tvix/store): drop separate bin package
Apparently, having multiple packages with the same path is a bad thing:

```
The bin target `tvix-store` in package `tvix-store-bin v0.1.0 (/home/flokli/tvl/tvix/store)` has the same output filename as the lib target `tvix_store` in package `tvix-store-bin v0.1.0 (/home/flokli/tvl/tvix/store)`.
Colliding filename is: /home/flokli/tvl/tvix/target/doc/tvix_store/index.html
The output filenames should be unique.
This is a known bug where multiple crates with the same name use
the same path; see <https://github.com/rust-lang/cargo/issues/6313>.
```

19c452875e feat(tvix): add simple initial website
The website itself contains no useful information that we don't
already have published anywhere, but it's a decent landing place.

Mostly I want to have something on the root of tvix.dev, so that we
can start using it for other purposes.
