97e4600078 refactor(nix-compat/wire/bytes/reader): move size reading to async ctor
with_size only existed to allow separating the phases of reading size
and reading data, and similarly the Size state only existed to allow
folding size reading into poll_read.

Neither of these are necessary if we make the constructor async,
and handle the size reading there.

As a bonus, this makes BytesReader::len sensibly typed, and permits
implementing is_empty, as Clippy demands of us.

fdecf52a52 refactor(nix-compat/wire/bytes): fold TrailerReader into BytesReader
The TrailerReader has no purpose separate from BytesReader, and the
code gets a fair bit simpler this way.

EOF handling is simplified, since we just rely on the implicit
behaviour of the existing case.

6e41e0917e feat(nix-compat/wire/bytes/reader): split out reading the trailer block
We separate ingesting the trailer block into a Future of its own,
parametrised on the specifics of the trailer pattern.

This is intended to be used for future work on an async NAR reader,
which needs to read a terminating parenthesis as well as the regular
padding.

Thanks to @griff for suggesting separating the ingestion into its own
Future.

ba46b1818a fix(nix-compat/bytes): make BytesReader less hazardous
We now *never* return the final bytes until we've read the padding
in full, so read_exact is safe to use.

This is implemented by TrailerReader, which splits the phases of
reading (and validating) the final 8-byte block, and providing
the contained payload bytes to the caller.

671bdff5dc test(tvix/nix-compat): add debug assertions for nar reader
Adds debug assertions to ensure that the reader's variants are upheld.
If any of the following happens, then the currently in use reader must
be abandoned:
  * A directory or file reader encounters an error
  * A directory or file reader is dropped before being fully read from
Additionally, a directory reader must not be read from again after it
has returned None.
These checks are only used when debug_assertions are on, so vanish in
release mode.

Resolves two TODO items added by edef

Moving out the handshake route out of tvix-daemon to nix-compat.

We're bumping the protocol to version 37. It does not change anything
for us. Version 37 introduced a change in the build result
serialization. We do not implement that for now.

Tested tvix-daemon against Nix via the integration test to make sure
we did not break anything in the process.

d00c75ea9c fix(nix-compat/store_path): fix Deserialize with borrow
We were wrongly using `'de` as a lifetime for both `Deserializer` and
`StorePathRef`.

This prevented Deserializing into a struct containing `StorePathRef`.

See https://serde.rs/lifetimes.html#the-deserializede-lifetime, the last
part of the paragraph:

The 'de lifetime should not appear in the type to which the Deserialize
impl applies.

- // Do not do this. Sooner or later you will be sad.
- impl<'de> Deserialize<'de> for Q<'de> {
+ // Do this instead.
+ impl<'de: 'a, 'a> Deserialize<'de> for Q<'a> {

This fixes it, and adds a test, deserializing into a `Container` struct.

It also fixes the existing test cases, deserialize_ref was actually
deserialize_owned, and deserialize_owned didn't exist yet - but they
alone are not enough to provoke the lifetime issues.

c35a5ff611 feat(users/picnoir/tvix-daemon): parse up to the operation
Using all the primitives recently implemented to nix-compat to reach
the point where the Nix client start to send us operation requests.

Using a small integration test script (or the VM test, but let's face
it, it's too slow to be useful), we manage to reach the point where
we're able to read a store operation:

    2024-03-21T18:53:27.624876Z  INFO tvix_daemon: Incoming connection addr=unix
    2024-03-21T18:53:27.625312Z  INFO worker:perform_init_handshake: tvix_daemon: Trust sent conn=Connection(unix) conn=Connection(unix)
    2024-03-21T18:53:27.625406Z  INFO worker: tvix_daemon: Client hanshake succeeded conn=Connection(unix)
    2024-03-21T18:53:27.625488Z  INFO worker: tvix_daemon: Operation received op=SetOptions conn=Connection(unix)

We had to take some shortcuts wrt. stderr/log management. The CPP Nix
codebase is a bit confusing in that area. I'll need to spend more time
reading this to fully understand what's happening there. For now,
sending the STDERR_LAST command to the client does the trick.

907ecff999 feat(nix-compat/wire): add low-level wire format primitives code
This brings some initial Nix wire format parsing code, used in the nix
daemon protocol, remote store/builder protocol, as well as the NAR
format itself (note we already have more specialized code for the last
one).

Thanks to embr, this code already exists, in
https://codeberg.org/gorgon/gorgon/src/branch/main/nix-daemon/src/wire.rs,
and we can vendor it into here, as EUPL is compatible with GPL (in that
direction).

The code uses the tokio::io Reader and Writer traits, not the ones from
the `futures` crate, as they provide some more convenient `read_u64_le`
functions.

More application-specific parsing code, as well as code to read strings,
or bytes are left out for now, as we want to be be more restrictive
w.r.t allowed max sizes, and need to parse bytes, not strings.

The code slightly diverges, as we have clippy looped into CI.
`Ok(…?)` can be turned into just the inner expression, and
some .and_then can be expressed in a simpler fashion.

The outer fingerprint used for store path calculation is always a sha256

We used a NixHash here, which can also represent other hash types, and
that had a bunch of annoyances:

 - Whenever we had the bytes, we had to wrap them in a NixHash::Sha256().
 - Things like AtermWriteable had to be implemented on NixHash,
   even though we then had an assertion it was only called in the
   NixHash::Sha256 case.

de727bccf9 feat(tvix/glue): Implement builtins.fetchurl
Implement the fetchurl builtin, and lay the groundwork for implementing
the fetchTarball builtin (which works very similarly, and is implemented
using almost the same code in C++ nix).

An overview of how this works:

1. First, we check if the store path that *would* result from the
   download already exists in the store - if it does, we just return
   that
2. If we need to download the URL, TvixStoreIO has an `http_client:
   reqwest::Client` field now which we use to make the request
3. As we're downloading the blob, we hash the data incrementally into a
   SHA256 hasher
4. We compare the hash against the expected hash (if any) and bail out
   if it doesn't match
5. Finally, we put the blob in the store and return the store path

Since the logic is very similar, this commit also implements a *chunk*
of `fetchTarball` (though the actual implementation will likely include
a refactor to some of the code reuse here).

The main thing that's missing here is caching of downloaded blobs when
fetchurl is called without a hash - I've opened b/381 to track the TODO
there.

Adding the `SSL_CERT_FILE` here is necessary to teach reqwest how to
load it during tests - see 1c16dee20 (feat(tvix/store): use reqwests'
rustls-native-roots feature, 2024-03-03) for  more info.

eff2cc4f68 fix(tvix/nix-compat): Make CAHash deserialize more formats
Currently CAHash only deserializes the hash in hex code while
the serializer outputs a nixbase32 hash. This means that you can't currently
deserialize what has been serialized.

This change makes deserialize support any digest format (so hex, nixbase32
and base64) as well as flattens the deserialize code and error handling.

It also implements serde methods of HashAlgo directly using Display and TryFrom
implementations because otherwise these would get serialized as eg. Sha256 instead
of sha256 which also broke CAHash serialize/deserialize.

260c2938d4 refactor(tvix/nix-compat): rename NixHash::{digest,hash}
This doesn't return the digest, but the internal NixHash.

To get the digest, you use `ca_hash.hash().digest_as_bytes()`
(as done in tvix/nix-compat/src/derivation/write.rs).

48d4d10bac refactor(tvix/nix-compat): derivation_or_fod_hash w/o self.clone()
Instead of constructing a completely new derivation for hashing,
allow to call hashing with substituted input_derivations.

This

1. reduces the number of allocations,
2. prepares substituting `String`s for store paths with proper `StorePath`s without needing a separate derivation struct that allows hashes without `/nix/store` in input_derivations, and
3. keeps the change local to the `Derivation` implementation.

In this commit, we accept SRI hashes of invalid padding and invalid length, as Nix does.

Real world example: `pkgs.javaPackages.openjfx11.deps`
<849e4dc5ff/pkgs/development/compilers/openjdk/openjfx/11.nix (L71)>
in nixpkgs.

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.
