Whether chunking is involved or not, is an implementation detail of each
Blobstore. Consumers of a whole blob shouldn't need to worry about that.
It currently is not visible in the gRPC interface either. It
shouldn't bleed into everything.
Let the BlobService trait provide `open_read` and `open_write` methods,
which return handles providing io::Read or io::Write, and leave the
details up to the implementation.
This means, our custom BlobReader module can go away, and all the
chunking bits in there, too.
In the future, we might still want to add more chunking-aware syncing,
but as a syncing strategy some stores can expose, not as a fundamental
protocol component.
This currently needs "SyncReadIntoAsyncRead", taken and vendored in from
https://github.com/tokio-rs/tokio/pull/5669.
It provides a AsyncRead for a sync Read, which is necessary to connect
our (sync) BlobReader interface to a GRPC server implementation.
As an alternative, we could also make the BlobReader itself async, and
let consumers of the trait (EvalIO) deal with the async-ness, but this
is less of a change for now.
In terms of vendoring, I initially tried to move our tokio crate to
these commits, but ended up in version incompatibilities, so let's
vendor it in for now.

We already returned UnexpectedEof in case the reader stopped returning
bytes too early, but similarly we should also fail if there's still
bytes left to be read in the reader passed.
We normally use the NAR writer to produce new NAR files, so the readers
point to the blobs we actually want to render, and having some data left
in there should be an error.
If for some reason the reader points to more data than just the blob,
the `.take` method can be used to limit it to the (known) size.

This makes sure that initializing coder-stream-mixin (for the most part)
has the same interface as initializing qbase64:decode-stream. This will
make integrating that as a faster replacement to
mime4cl:base64-decoder-stream a bit easier.
The idea is to replace the char by char base64 decoder with one that
supports read-sequence. After that deliminited-input-stream needs to
gain support for read-sequence as well, so we can actually take
advantage of this fact. Finally, we'll have to evaluate the remaining
decoders and think about switching the (base64) encoders over as well.

For whatever reason, there were two sort of identical tests, mime.1 and
mime.2, in the mime4cl test suite: The former tested *sample1-file* and
the latter all messages *samples-directory*—in the same way, parsing the
original and a re-rendered version of the message to check if they were
equal.
We can just move sample1.msg into *samples-directory*, get rid
of *sample1-file* and thus pave the way for more test messages in the
future.

These packages are invalid in Nix, and worked around in nixpkgs with
underscores, but the underscores are invalid in the Docker registry
protocol.
We work around this by detecting this case and adding the underscore
to yield the correct package reference. There is no case where this
workaround can break something, as there can be no valid package
matching the regular expression.
This relates to https://github.com/tazjin/nixery/issues/158

This uses tonic to generate the full set of gRPC clients for Yandex

interceptor to make these actually work.
Since the upstream protos are exported regularly I've decided that the
versioning will simply be date-based.
The point of this is journaldriver integration, of course, hence also
the log-centric example code.

* //3p/sources: Note that emacs-overlay is not updated for now, as
changes in emacs HEAD break //users/sterni/emacs.
* //3p/gerrit_plugins/code-owners: deps hash changed once again
or was no longer in the Nix store.
Unfortunately, building the deps derivations from scratch for gerrit
and the gerrit plugins no longer works due to a nixpkgs regression:
Due to a (operator precedence) mistake in the way the deps
derivation's installPhase is computed, it would append extra code to
the installPhase provided by us, causing a bash syntax error.
I have proposed a fix for this
upstream (<https://github.com/NixOS/nixpkgs/pull/228305>). Adding a
workaround in the repo would be possible, but a bit annoying. Since
the derivations are fixed output anyways, I've opted to build the
missing deps derivation (for code-owners) locally using the fixed
nixpkgs, updated the sha256 and copied the result into whitby's Nix
store. Hopefully by the next time we'll be rebuilding the deps
derivations again the fix will have propagated into the NixOS unstable
channel.

What's basically happening now is that the credentials for the state

Before there was code scattered about (e.g. text hashing module and
derivation output computation) constructing store paths from low level
building blocks --- there was some duplication and it was easy to make
nonsense store paths.
Now, we have roughly the same "safe-ish" ways of constructing them as
C++ Nix, and only those are exposed:
- Make text hashed content-addressed store paths
- Make other content-addressed store paths
- Make input-addressed fixed output hashes
