155ab77cff refactor(tvix/nar-bridge): use mh.SHA2_256
As correctly mentioned in
https://cl.tvl.fyi/c/depot/+/9652/comment/03b9b96e_bbb337fd/,
we shouldn't be using these magic constants, but pull them from where
they're defined.

This already is a dependency of go-nix, and pkg/pathinfosvc/server.go,
so no changes in go.mod.

98c17147c6 refactor(tvix/nar-bridge): have Export return root node
… and nar size / sha256 digest.

Instead of producing sparse PathInfo messages when NARs are sent to
nar-bridge, the nar-bridge http server now keeps a lookup table
(narsha256) -> (rootNode, narSize)

This removes a whole bunch of noise, because we don't need to keep
sparse fields around.

A convenience function
`GenPathInfo(rootNode *castorev1pb.Node, narInfo *narinfo.NarInfo)` is
added, which is used to produce PathInfo messages, either when receiving
a NAR file over http and uploading it to a remote PathInfoService, or to
synthesize the PathInfoMessage to return to the client, if nar-bridge is
acting as a PathInfoService for a remove Nix HTTP Binary cache.

e6ba84ea50 feat(tvix/store/protos): add Export
Export will traverse a given PathInfo structure, and write the contents
in NAR format to the passed Writer.
It uses directoryLookupFn and blobLookupFn to resolve references.

This is being moved over from nar-bridge. We need to keep the code there
around until we can bump go.mod to storev1 with this merged, but the
tests can already be moved entirely.

c04041a001 feat(tvix/nar-bridge): add nar-bridge-pathinfo command
This adds an additional nar-bridge-pathinfo command.

It exposes a PathInfoService for a HTTP Binary Cache, ingesting data
into a BlobService/DirectoryService as it goes through the NAR file.

It does this whenever it receives a Get request for a specific output
path, and waits returning with the PathInfo response until it ingested
the data.
It does not do any sort of caching - this means it re-downloads NAR
files again whenever the PathInfo is requested again, so you most likely
do not want to use this currently.

It's one building component as soon as we have store composition (which
we currently don't, so don't use this).

It can be used as an alternative mechanism to ingest data (Blobs and
Directories) of a given store path from a binary cache into tvix-store.

dd7cc6ed68 fix(tvix/nar-bridge): don't log error on simple 404s
`nix copy` checks if NARs and NARInfo files are present, before
uploading them. That's not an error, but normal behaviour, so no need to
log with level info for these cases.

We only want to log if the error is not a 404, and log with Warn level.

way too large proto messages, chunk blobs up to a reasonable (1MiB)
chunk size, and send them to the server like that.

`break`/`continues` that can be replaced by moving the conditional into
the for loop condition.

84aa07a736 fix(tvix/nar-bridge): Fix directory stack tracking
Previously, nar-bridge, had a couple of bugs with tracking the current
directory when traversing a NAR file.

The included test case looks like:
```
/ (dir)
/test (dir)
/test/tested (file)
/tested (file)
```

Previously, we would do a string prefix match between the current node
and the top of the directory stack to determine if the node is in the
directory. In this case `/test` is a substring of `/tested`; however,
`/tested` is not in the `/test` directory. The fix is to append a `/` to
the directory name when doing the prefix match, so `/test/` is not a
prefix of `/tested`.

Additionally, when popping the stack, we need to continuously pop the
stack until the new node is in the directory at the top of the stack
(stopping before we pop the root directory)

Example:
```
/ (dir)
/a (dir)
/a/b (dir)
/a/b/c (file)
/z (file)
```

Previously, `z` would end up in directory `/a` because we only the pop
the stack once.

The included test case requires both of these issues to be fixed for it
to pass, so I think it is sufficient.

In some cases, Nix is not able to stream the NAR file fast enough. Bump the
timeouts for now. We might want to get a better understanding in what's
happening here long-term, and/or make the timeouts configurable.

0ecd10bf30 feat(tvix/nar-bridge): init
This provides a Nix HTTP Binary Cache interface in front of a tvix-store
that's reachable via gRPC.

TODOs:

 - remove import command, move serve up to toplevel. We have nix-copy-
   closure and tvix-store commands.
 - loop into CI. We should be able to fetch the protos as a third-party
   dependency.
 - Check if we can test nar-bridge slightly easier in an integration
   test.
 - Ensure we support connecting to unix sockets and grpc+http at least,
   using the same syntax as tvix-store.
 - Don't buffer the entire blob when rendering NAR
