When the nix daemon starts up, first check (using sd_listen_fds) whether we have been systemd socket-activated. If so, instead of passing the nix daemon socket path to grpc, start a manual accept(2) loop, passing the client file descriptors to grpc via AddInsecureChannelFromFd. There's an open grpc issue at https://github.com/grpc/grpc/issues/19133 for building support into grpc to do this automatically, but as of right now this appears to be the only way to make this happen. Making this happen, by the way, was a bit of a journey - at one point I attempted to ServerBuilder's experimental AddExternalConnectionAcceptor API, and that didn't work either - it appears that the final missing piece to getting this working was explicitly fcntl(2)ing the client file descriptors to set O_NONBLOCK before passing them into gRPC. With that set, this all works inside of the test vm.

depot
This repository is the monorepo for the community around tazjin's virus lounge, containing our personal tools and infrastructure. Everything in here is built using Nix.
A large portion of the software here is very self-referential, meaning that it exists to sustain the operation of the repository. This is the case because we partially see this as an experiment in tooling for monorepos.
If you've ended up here and have no idea who I am, feel free to follow me on Twitter.
Highlights
Services
-
Source code is available primarily through Sourcegraph on cs.tvl.fyi, where it is searchable and even semantically indexed. A lower-tech view of the repository is also available via cgit on code.tvl.fyi.
The repository can be cloned using
git
fromhttps://cl.tvl.fyi/depot
. -
All code in the depot, with the exception of code that is checked in to individual
//users
folders, needs to be reviewed. We use Gerrit on cl.tvl.fyi for this. -
Issues are tracked via our own issue tracker on b.tvl.fyi. Its source code lives at
//web/panettone/
. -
Smaller todo-list entries which do not warrant a separate issue are listed at todo.tvl.fyi.
-
We use Buildkite for CI. Recent builds are listed on tvl.fyi/builds and pipelines are configured dynamically via
//ops/pipelines
.
All services that we host are deployed on NixOS machines that we manage. Their
configuration is tracked in //ops/nixos
.
Nix
//third_party/nix
contains Tvix, our fork of the Nix package manager//nix/readTree
contains the Nix code which automatically registers projects in our Nix attribute hierarchy based on their in-tree location//nix/yants
contains Yet Another Nix Type System, which we use for a variety of things throughout the repository//nix/buildGo
implements a Nix library that can build Go software in the style of Bazel'srules_go
. Go programs in this repository are built using this library.//nix/buildLisp
implements a Nix library that can build Common Lisp software. Currently only SBCL is supported. Lisp programs in this repository are built using this library.
We have a variety of other tools and libraries in the //nix
folder which may
be of interest.
