This adds a function that consumes a [proto::node::Node] pointing to the
root of a (store) path, and writes the contents in NAR serialization to
the passed [std::io::Write].
We need this in various places:
- tvix-store's calculate_nar() RPC method needs to render a NAR stream
to get the nar hash, which is necessary to give things imported in
the store a "NAR-based" store path.
- communication with (remote) Nix (via daemon protocol) needs a NAR
representation.
- Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a
NAR representation.

We only do logic here if algo and hash_mode are Some(_)

The fact we don't do anything in all in other cases is a bit hidden at

There is a code path in public-inbox that will (under certain
conditions) set the expected list-id as derived from the recipient
mail address (so in our case depot@tvl.su -> `List-ID: depot.tvl.su`).
However, when/how this triggers seems to be particular to the code
path taken based on certain config settings. I couldn't fully figure
it out, and to be honest I don't really know Perl, and I don't think
this warrants a super-high-effort investigation.
For that reason, this patches the appropriate line in
public-inbox-watch to always trigger this code path regardless of what
is going on with the email.
I tested this locally with a public-inbox config that does *not* have
a `listid` setting set, as that just adds an additional filter which
would be a no-op in this case. All emails are ingested correctly with
List-ID set.
There might be a better place to put this in (e.g. right before the
actual mail ingestion), if a Perl expert is interested in figuring
this out and considers it relevant, feel free to send a CL.
Note that this will not update old emails. Probably.

Instead of being called with `md5`, `sha1`, `sha256` or `sha512`,
`fetchurl.nix` (from corepkgs / `<nix`) can also be called with a `hash`
attribute, being an SRI hash.
In that case, `builtin.derivation` is called with `outputHashAlgo` being
an empty string, and `outputHash` being an SRI hash string.
In other cases, an SRI hash is passed as outputHash, but outputHashAlgo
is set too.
Nix does modify these values in (single, fixed) output specification it
serializes to ATerm, but keeps it unharmed in `env`.
Move this into a construct_output_hash helper function, that can be
tested better in isolation.

This uses the actual upstream Nix code for

We're doing it this way to ensure that our thunking logic is correct.
An initial Rust-native rewrite (see e.g. cl/7363) is pretty difficult
to debug while there are still other issues to root out, but
eventually we might want to turn this into native code.

Apparently our naive implementation of float formatting, which simply
used {:.5}, and trimmed trailing "0" strings not sufficient.
It wrongly trimmed numbers with zeroes but no decimal point, like
`10000` got trimmed to `1`.
Nix uses `std::to_string` on the double, which according to
https://en.cppreference.com/w/cpp/string/basic_string/to_string
is equivalent to `std::sprintf(buf, "%f", value)`.
https://en.cppreference.com/w/cpp/io/c/fprintf mentions this is treated
like this:
> Precision specifies the exact number of digits to appear after
> the decimal point character. The default precision is 6. In the
> alternative implementation decimal point character is written even if
> no digits follow it. For infinity and not-a-number conversion style
> see notes.
This doesn't seem to be the case though, and Nix uses scientific
notation in some cases.
There's a whole bunch of strategies to determine which is a more compact
notation, and which notation should be used for a given number.
https://github.com/rust-lang/rust/issues/24556 provides some pointers
into various rabbit holes for those interested.
This gist seems to be that currently a different formatting is not
exposed in rust directly, at least not for public consumption.
There is the
[lexical-core](https://github.com/Alexhuszagh/rust-lexical) crate
though, which provides a way to format floats with various strategies
and formats.
Change our implementation of `TotalDisplay` for the `Value::Float` case
to use that. We still need to do some post-processing, because Nix
always adds the sign in scientific notation (and there's no way to
configure lexical-core to do that), and lexical-core in some cases keeps
the trailing zeros.
Even with all that in place, there as a difference in `eval-okay-
fromjson.nix` (from tvix-tests), which I couldn't get to work. I updated
the fixture to a less problematic number.
With this, the testsuite passes again, and does for the upcoming CL
introducing builtins.fromTOML, and enabling the nix testsuite bits for
it, too.
