b70e01a4db feat(tvix/castore/import): remove copying in find_ancestor
We don't need to copy if we explicitly say that the returned
Option<Path> may hold onto bytes from the passed in &DirEntry.

a919efbe11 fix(tvix/eval): fix the unsafeGetAttrPos stub return value
It was returning `{ line, col, file }` instead of `{ line, column, file
}`.

Note this is not a regression in Nix, Nix always had `column` since
2013.

01f8ef1560 fix(tvix): apply cbtemulator patch in tvix view
This tells josh to include the patch from
third_party/overlays/patches/cbtemulator-uds.patch at
nixpkgs/cbtemulator-uds.patch.

We then use the `additionalOverlays` feature introduced earlier, and
pass it an overlay adding the patch to `cbtemulator`.

This only gets applied if tvix/shell.nix is not called with a pkgs
argument, which is the case in the tvix view.

820e98fa7f refactor(tvix/boot): use tvix-store copy
Instead of using an additional Nix build producing a directory structure
containing xz-compressed NAR files and NARInfos, and uploading these via
`curl` to NAR-bridge, which then decomposes them and uploads them to
tvix-store, have tvix-store interpret the exported reference graph
directly, and deal with the uploading on its own.

a4f65ddba0 feat(tvix/store/bin): add "copy" command
This allows copying individual store paths from the local /nix/store
into tvix-store.

As we don't support getting this information from Nix yet, we currently
expect metadata to be provided externally:

Nix' `exportReferencesGraph` feature contains pretty much all data we
need for this. Expect a list of this information at a well-known key
(`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/
default.nix`).

We currently simply upload all store paths sequentially, without any
parallelism or awareness in how the reference graph looks like.

As long as the connected stores don't enforce this, this is fine, at
least for now.

863c4207cc feat(tvix/eval): contextful JSON operations
`toJSON` transform a Nix structure into a JSON string.

For each context in that Nix structure, the JSON string must possess it.

Thus, it is necessary to take the union of all contexts and attach it to
the final structure.

Unfortunately, the return type of `into_json` is a serde's JSON object,
not a string. Therefore, it is not possible to reuse `NixString`
machinery.

Context tests are reinforced as Nix does not test those behaviors.

Fixes b/393.

63116d8c21 fix(tvix): Avoid buffering file into memory in builtins.hashFile
Right now `builtins.hashFile` always reads the entire file into memory
before hashing, which is not ideal for large files. This replaces
`read_to_string` with `open_file` which allows calculating the hash of
the file without buffering it entirely into memory. Other callers can
continue to buffer into memory if they choose, but they still use the
`open_file` VM request and then call `read_to_string` or `read_to_end`
on the `std::io::Reader`.

acee489866 refactor(tvix/nix-compat/wire): simplify write_bytes a bit
Use the same EMPTY_BYTES trick from BytesWriter to write out the
padding, rather than allocating a Vec.

This isn't used anywhere so far, and if someone really wants to, they

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.

efd8ab5e0b feat(users/picnoir/tvix-daemon): implement set_options operation
The protocol is more stateful than I initially thought. We need to
keep track to a bunch of things, including but not limited to: the
client settings, the client version. I moved things around a bit to
keep this state along with the client socket.

199f9b0a79 feat(tvix/nix-compat): read client setting from wire
Add the primitives necessary to read the client settings from the Nix
daemon wire protocol.

Introducing the read_string primitive. This trivial primitive parses a
read_bytes call, check the bytes are valid utf-8 bytes and wraps the
result in a String.
