62184ee35a docs(tvix): document the builder API
This documents some thoughts and goals of the Tvix Build protocol, and
how it is possible to express Nix builds with it.

Additionally, it explains a proposed design for reference scanning.

76394daca3 feat(tvix/composition): downcast boxed error if possible
We still have the unique store name to identify which instantiation caused the error. For recursion errors, the full chain is still retained inside the CompositionError.

1515a970be feat(tvix/tracing): http propagation for axum
It introduces a new accept_trace function for axum0.7 which can be used
to accept a header trace from a received request. This function can be
used for tonic 0.12 once that version is released, and the specific
`accept_trace` function within `tvix_tracing::propagate::tonic` can then
be removed.

This also integrates http propagation into the nar_bridge crate.

d136f2c881 fix(tvix/nar-bridge): fix root node decoding and validation
This got broken while moving things around. We need to parse the
b64-decoded bytes.

Since we're now validating the root node, we also need to rename the
root node to get past the node name validation.

There probably should be some tests for this.

fca8462530 fix(tvix): fix outputHashes calculation for crates with versions
In case two crate versions are present, the key in the Cargo.nix file
includes the version number too.

To be able to set a specific hash for "tracing-opentelemetry 0.25.0" for
example, this needs to account for keys with the version included.

Access `crateName`, `version` and `src.outputHash` individually.

5bd48de418 feat(tvix/nar-bridge): add 404 handler for GET/HEAD /nar/…
We currently send 405, and that confuses `nix copy`.
Send a 404 for now, and add a futurework, as we can actually at least do
something more meaningful in case we still have that nar hash in our
LRU, which would avoid some unnecessary uploads in some cases.

5d906054da feat(tvix/nar-bridge): support uploading NAR files
This ingests NAR files into the {Blob,Directory}Service, which are
already part of the AppState.

As we then need to correlate the root node to the uploaded PathInfo, we
need to keep a (short-lived) lookup table from NARHash to root node
around. We insert it into a `LruCache` after the NAR is uploaded, and
use `peek()` to do the lookup, which doesn't update the LRU list.

861cc1f341 feat(tvix/nar-bridge): init
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
soon.

c05bf02a85 chore(3p/gerrit): create buildBazelPackageNG and migrate gerrit to it
This bumps Gerrit to 3.10.0, and also introduces a new mechanism for
building it that should hopefully have some more stable hashes than the
previous bodgery.

In this world, we only cache what we explicitly want to. There are some
hooks implemented for `rules_java` and `rules_nodejs` (before version
6) that force use of local binaries; this means we can drop the use of
the FHSUserEnv and use the java and nodejs binaries provided by nixpkgs
instead.

detzip is deleted; it hasn't been used in yonks.

We also add https://gerrit-review.googlesource.com/c/gerrit/+/431977,
which bumps the SSHd version so that we can have U2F-based SSH keys.

8821746d6c fix(tvix/repl): Share globals and sourcemap across evaluations
Now that we can bind (potentially lazy, potentially lambda-containing)
values in the REPL and then reference them in subsequent evaluations,
it's important that the values to which we construct shared references
are shared across those subsequent evaluations - otherwise, we get
panics due to unknown source map locations, or dropped weak references
to globals.

This change assigns both the globals and the source map as fields on the
Repl after the first evaluation, and then passes those in (to the
EvaluationBuilder) on subsequent evaluations.

On the EvaluationBuilder side, there's some panicking introduced - this
is intentional, as my intent is for the builder to be configured
statically enough that panicking is the best way to report errors
here (it's always a bug to misconfigure an Evaluation, and we'd never
want to handle it dynamically).

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.

3a79f93795 refactor(tvix/eval): Construct globals in EvaluationBuilder::build
Construct the Rc<GlobalsMap> for the evaluation as part of
EvaluiationBuilder::build, rather than deferring it until we actually
compile. This changes nothing functionally, but gets us one step closer
to sharing this globals map across evaluations.

dfe137786c refactor(tvix/eval): Builderize Evaluation
Make constructing of a new Evaluation use the builder pattern rather
than setting public mutable fields. This is currently a pure
refactor (no functionality has changed) but has a few advantages:

- We've encapsulated the internals of the fields in Evaluation, meaning
  we can change them without too much breakage of clients
- We have type safety that prevents us from ever changing the fields of
  an Evaluation after it's built (which matters more in a world where we
  reuse Evaluations).

More importantly, this paves the road for doing different things with
the construction of an Evaluation - notably, sharing certain things like
the GlobalsMap across subsequent evaluations in eg the REPL.

7ca32d9f0b refactor(web/tvixbolt): buildRustPackage -> crate2nix
With the recent changes to crate2nix and buildRustCrate in nixpkgs it is
now possible to build tvixbolt via crate2nix like we do for other tvix
crates. We can reuse a lot of the customizations done in //tvix in
tvixbolt to avoid repeating ourselves.

A script for serving tvixbolt locally for testing purposes is also
available now through the .serve attribute of tvixbolt.

This change supersedes https://cl.tvl.fyi/c/depot/+/11821.

63654fbeb1 fix(tvix/utils): Optionally add support for Cargo in filterRustCrateSrc
Previously we would unconditionally add Cargo.toml to the fileset. We
mostly use buildRustCrate in tvix so it does not make sense to add it by
default, instead I made it so you enable cargoSupport if you want
Cargo.{toml,lock} to be added to the fileset.

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

ac3d717944 feat(tvix/eval): Allow passing in an env to evaluation
Allow passing in a top-level env, a map from name to value, to
evaluation. The intent is to support bound identifiers in the REPL just
like upstream nix does.

Getting this working involves mucking around a bit with internals - most
notably, locals now only optionally have a Span (since locals don't have
an easy span we can use) - and getting that working requires propagating
some minor hacks to places where we currently *need* a span (and which
would require too much changing now to make spans optional; my guess is
that that would essentially end up making spans optional throughout the
codebase).

Also, some extra care has to be taken to close out the scope in the case
that we do pass in an env, to avoid breaking our assumptions about the
size of the stack when we return from the toplevel

af933c177a docs(tvix): update WASM status
crate2nix can now build WASM, and cl/11859 showcases this now.

Even if it's not in the same cargo workspace, we should still migrate
tvixbolt to a crate2nix build.

Remove the part about Build/Store frontends, it was more of an
explanation why we want WASM builds to be nice, it can be tracked in
separate TODOs once more concrete.
