27fecee1bc fix(tvix/eval): don't increase with_stack_size in scope inherits
There was probably a misunderstanding somewhere about the
with_stack_size being related to how far away it is from the with, but
it is about whether there is a with at all.

This broke a warning (`UselessInherit`), and may actually have let to
more inefficient codegen in some cases.

77cc6a1f78 refactor(tvix/derivation): make output hashes an Option<Hash>
This conveys better if an output of a Derivation is fixed-output or not,
and provides a Hash struct that can be used to store the algo and
digest.

In case it's not, this can simply be None. The serde field attributes
have been updated to still accept the same JSON.

We currently still store the hash algo and digest as strings, mostly
because the only thing populating it so far is the example JSONs.
We might want to update this, once actual Nix code populates this.

While updating write.rs, I pushed some of the Vec<String> to [&str]
conversions inline, and made it a Vec<&str>, because it was annoying to
juggle with.

9b8ba915c8 fix(tvix/eval): ' is allowed in nonfirst position in Nix identifiers
With this is_valid_nix_identifier should line up with the upstream lexer
definition:

    ID          [a-zA-Z\_][a-zA-Z0-9\_\'\-]*

While we're working on this, add a simple test checking the various
formatting rules. Interestingly, it would not be suitable as an identity
test, since you have to write

    { "assert" = null; }

in order to avoid an evaluation error, but C++ Nix is happy to print
this as

    { assert = null; }

– maybe should be considered to be a bug.

3d238c350b refactor(tvix/eval): streamline construction of globals/builtins
Previously the construction of globals (a compiler-only concept) and
builtins (a (now) user-facing API) was intermingled between multiple
different modules, and kind of difficult to understand.

The complexity of this had grown in large part due to the
implementation of `builtins.import`, which required the notorious
"knot-tying" trick using Rc::new_cyclic (see cl/7097) for constructing
the set of globals.

As part of the new `Evaluation` API users should have the ability to
bring their own builtins, and control explicitly whether or not impure
builtins are available (regardless of whether they're compiled in or
not).

To streamline the construction and allow the new API features to work,
this commit restructures things by making these changes:

1. The `tvix_eval::builtins` module is now only responsible for
   exporting sets of builtins. It no longer has any knowledge of
   whether or not certain sets (e.g. only pure, or pure+impure) are
   enabled, and it has no control over which builtins are globally
   available (this is now handled in the compiler).

2. The compiler module is now responsible for both constructing the
   final attribute set of builtins from the set of builtins supplied
   by a user, as well as for populating its globals (that is
   identifiers which are available at the top-level scope).

3. The `Evaluation` API now carries a `builtins` field which is
   populated with the pure builtins by default, and can be extended by
   users.

4. The `import` feature has been moved into the compiler, as a
   special case. In general, builtins no longer have the ability to
   reference the "fix point" of the globals set.

This should not change any functionality, and in fact preserves minor
differences between Tvix/Nix that we already had (such as
`builtins.builtins` not existing).

Unfortunately, we can only update the filters one-by-one (a common

The function & error message said it was searching upwards for
shell.nix, but it didn’t actually search upwards.

7168cb0ed3 feat(users/Profpatsch/mailbox-org): init
A smol little tool to talk to the mailbox.org backend. This is handy
for eventually setting stuff like email filters. Their API is absolute
crap, but we’ll deal with it.

Updates the prelude & adds some pretty printing helpers.

319c03f634 feat(tvix/store): add logging with tracing
This uses [tracing](https://github.com/tokio-rs/tracing) for logs/
tracing.

Annotate all method handlers with an instrument macro, and warn! a
message for them being unimplemented.

0bf2b0ef11 feat(tvix/store): implement reflection
This implements grpc.reflection.v1alpha.ServerReflection, and will make tools
like evans automatically discover available services, without having to
specify the path to the .proto files client-side.

It's behind a reflection feature flag, which is enabled by default.

PathInfoService.

All RPC methods currently respond with the unimplemented gRPC status.

357c4d4836 feat(tvix/store): add nixbase32 mod
This implements the nix-specific base32 encoding and decoding, exposing
a subset of the API that the data-encoding crate provides.

Nix uses a custom alphabet, no padding, and encodes bytes in reverse
order. The latter one is the reason we can't just use the data-encoding
crate directly.

Three odd corner case tests ported over from go-nix failed. We opened
b/235 to further investigate.
