ff40332864 refactor(tvix/store/nar/import): add ingest_nar_and_hash
This wraps ingest_nar, but also keeps track of the number of bytes read,
and calculates the sha256 digest of it.

Make use of it in the NixHTTPPathInfoService, where this code is coming
from.

beb7f57c73 fix(tvix/eval): handle builtins.split matching the empty string
This prevents the following statements from looping endlessly:

```
builtins.split "(.*)" ""
builtins.split "([abc]*)" "abc"
builtins.split "(.*)" "abc"
builtins.split ".*" ""
```

Cover these (and some more examples) in the test suite.

825d498908 feat(tvix/tracing): introduce common tvix-tracing crate
Introduce a new common crate that contains tracing boilerplate which then
can be used in the cli, tvix-store and tvix-build crates.
It has otlp as an optional feature, which is currently only used by
tvix-store.

d3bc358bbc docs(tvix/docs/TODO): document crate2nix for WASM attempts
I tried moving web/tvixbolt to tvix/tvixbolt, and adding it to the cargo
workspace.

I then made `crates =` in `default.nix` a function accepting `pkgs`
(so we can pass in another nixpkgs for some invocations), and then
constructed another nixpkgs and crates instance like this:

```
  pkgs-wasm = (import pkgs.path {
    localSystem = localSystem;
    crossSystem = {
      system = localSystem;
      rustc.config = "wasm32-unknown-unknown";
    };
  }
  crates-wasm = (crates pkgs-wasm);
  tvixbolt-test = crates-wasm.workspaceMembers.tvixbolt.build;
```

… leading to the architecture build failures described in the TODO.

23e0973cdf docs(tvix): fix some typos across various documents
Fix some typos found while reading various documents, mostly those
relating to the castore.

Here is a summary of the edits.

- fix broken link between documents in the store and castore directories
- clarify expression in castore's data model document that indicates
  that the *name* of each child node of a directory must be unique
  across all three lists of children
- add missing closing parenthesis in castore's data model document
- replace "how" with "what" in the phrase "unclear how a ... would even
  look like" in castore's why-not-git-trees document
- remove unnecessary articles in castore's blobstore chunking document
- add missing "y" to "optionall" in eval's compilation of bindings
  document

71435d9546 chore(3p/sources): Bump channels & overlays
* agenix has not been updated (https://github.com/ryantm/agenix/pull/241).
* wasm-bindgen bumped to 0.2.92 in Rust WASM projects
* 3p/lisp: port lispPackages from stable channel

  The Lisp package set we are using (`pkgs.lispPackages`) is the "old
  old" package set, whereas we were supposed to have been using
  `pkgs.lispPackages_new` (which is the "old new" package set).

  Either way we missed that train, and now there's a "new new" package
  set, but with a twist: Lisp packages in nixpkgs are now tied to
  their compilers, so the most generic way to access them seems to be
  from `pkgs.sbclPackages`.

  Switching to the packages from the "new new" package set doesn't
  work: Lots of stuff stops building if we just switch the sources
  over, and not everything is trivially fixable.

  For now we stay on the lispPackages from the stable channel. We need
  to look into the migration later.

  Or rewrite panettone.
* tvix: update generated protobuf files
* 3p/nixpkgs: pick trunk from stable channel; newer versions try to
  read files and do network I/O during build, but don't print enough
  details in error messages to figure out why.
* 3p/overlays: remove tdlib override (nixpkgs is currently new enough)
* 3p/overlays: override telega.el sources while updates are lagging in
  nixpkgs
* users/flokli/ipu6-softisp: update firmware paths, which NixOS now
  stores zstd-compressed.

20513e7a52 feat(tvix/store/bin): add progress bar infrastructure
This adds the tracing-indicatif crate, and configures it as a layer in
our tracing_subscriber pipeline to emit progress for every span that's
configured so.

It also moves from using std::io::stderr to write logs to using their
writer, to avoid clobbering output.

Progress bar styles are defined in a lazy_static, moving this into a
general tracing is left for later.

This adds some usage of this to the `imports` and `copy` commands.

The output can still be improved a bit - we should  probably split each
task up into a smaller (instrumented) helper functions, so we can create
a progress bar for each task.

72b9a126b8 feat(tvix/glue): Implement builtins.storePath
This one's relatively simple - we just check if the store path exists,
and if it does we make a new contextful string containing the store path
as its only context element.

Automatic testing seems tricky for this (I think?) so I tested it
manually:

tvix-repl> builtins.storePath /nix/store/yn46i4xx5alh7gs6fpkxk430i34rp2q9-hello-2.12.1

1b39d5868a feat(tvix): add CI targets for checking crate features powerset
Closes: https://b.tvl.fyi/issues/401

With this change all crate features (and their combinations) will be built and
tested in CI.

From now on, when adding/removing a Cargo feature for a crate,
you will want to add it to the features power set that gets tested in CI.
For each crate there's a default.nix with a `mkFeaturePowerset` invocation,
modify the list to include/remove the feature.
Note that you don't want to add "collection" features,
such as `fs` for tvix-[ca]store or `default`.

2c628f6e1c refactor(tvix/eval): move nix_tests to separate module
Gate this behind the nix_tests feature flag (which wasn't applied
consistently).

Also, at least right now all of these use StdIO internally, either by
creating it on their own, or through the `eval_test` helper.

Once we have some proper classification system for tests we can probably

9586e5c30d refactor(tvix/castore): move src/fs/test into fuse mod
These tests only interact with the FUSE layer, and
import super::fuse to do its work.

However, this only works if the `fuse` feature is enabled, which we
don't do if we enable the `virtiofs` feature only, causing the tests
to fail:

```
❯ cargo test --no-default-features --features virtiofs
   Compiling tvix-castore v0.1.0 (/home/flokli/dev/nixos/code.tvl.fyi-submit2/tvix/castore)
error[E0432]: unresolved import `super::fuse`
  --> castore/src/fs/tests.rs:14:13
   |
14 | use super::{fuse::FuseDaemon, TvixStoreFs};
   |             ^^^^ could not find `fuse` in `super`
```

We move src/fs/tests.rs to src/fs/fuse/tests.rs
(and src/fs/fuse.rs to src/fs/fuse/mod.rs) to better structure this,
which will automatically cause both tests and code to only be built if
we have the `fuse` feature enabled.

3ebcf30b64 feat(tvix): filter src via lib.fileset
Previously changing any file (including default.nix or README.md) would
cause Nix to compute a different derivation path, resulting in needing
to (very often redundantly) rebuild the crate/package. With this change
you can expect less rebuilds.

Crate2nix currently does its own insufficient src filtering and it does
not expose an API to override the filtering, so instead I created a
function that we can use to override the src to have stricter filtering.

I implemented the filtering for all of the workspace members, if you
want to modify any of them, please read the lib.fileset docs
https://nixos.org/manual/nixpkgs/unstable/#sec-functions-library-fileset

Both `Some(NixContext::new())` and `None` represent empty contexts,
but the former trips up `NixString::has_context`, and seems likely
to trip up other things.

We could hide the difference in the accessors, but we don't really
*want* the distinction to exist, since heap-allocating a null value
is pretty much always a mistake.

ec8d79f3db feat(tvix/eval): teach builtins.toXML context
XmlEmitter gains a NixContext field, and `write_typed_value` extends it
with all context elements present in the passed value.

Once all serialization is done, a into_context() function returns the
collected context, so we can construct a NixString with context.

Tests for this live in tvix-glue, as we use builtins.derivation, which
is not present in the tvix-eval crate.

Fixes b/398.

5b2ba0efa1 refactor(tvix/eval): rewrite xml emitter to be simple-stupid
In order to be compatible with the nix XML generator, it’s easier to
generate the XML directly, instead of going through a library which we
have to bend to do what we need.

Removes dependency on `xml-rs`, which came with a full XML parser that
we didn’t use. Only takes a tiny bit of code for the XML escaping,
somewhat simplified.

I add a little escaping value, to make sure we have the same behaviour
as nix proper.

Interestingly enough, we never need to escape XML attribute names,
because the `builtins.toXML` format encodes user-defined values as
attribute keys only. So we only escape attribute values.

e7be342256 feat(tvix/store): concurrently upload small blobs during nar ingestion
Currently all blobs are uploaded serially when ingesting NARs. If a NAR
contains many, small blobs, ingestion may become slow if there is a lot
of round-trip latency to the blob service.

This makes the NAR ingester use the ConcurrentBlobUploader which allows
for buffering small blobs in memory so they can be uploaded concurrently
to the blob service without blocking further deserialization.

Other ingestion sources like NARs also need a similar mechanism, this

make it more reusable.
