2024-06-29 r/8322 feat(tvix/boot): introduce useNarBridge parameterFlorian Klink1-2/+50
This is still useful to test the ingestion part of nar-bridge. Reintroduce the logic removed in cl/11398, but put it behind a `useNarBridge` parameter, defaulting to false. Add an additional target to tvix.boot.tests, `closure-nixos-nar-bridge`, which does the same as `closure-nixos`, except seeding the contents through nar-bridge.

These fields don't need to be set if isClosure is false. Change-Id: Id29ed034e0757c61cef09885962dfc5507ca106c Reviewed-on: https://cl.tvl.fyi/c/depot/+/11890 Tested-by: BuildkiteCI Autosubmit: flokli <flokli@flokli.de> Reviewed-by: Connor Brewster <cbrewster@hey.com>
2024-05-11 r/8100 chore(tvix/castore/blob): remove sled implementationFlorian Klink1-7/+2
This never did any chunking, and sled (rightfully) performs really bad if values get too large. We switched the default to using the objectstore backend with the local filesystem a while ago, no need to keep this footgun around anymore.

2024-04-16 r/7951 feat(tvix/boot): boot nixos VMFlorian Klink1-0/+34
This makes use of the vmCmdline and assertVMOutput to boot a NixOS VM off of `tvix-store virtiofs` have it write a message on successful bootup, then have it shut down again. We check we see the message in the output. Seeding the store with the closure it's what's currently taking most of the time (as it's all linear still), so log a message before booting the VM.

2024-04-13 r/7901 refactor(tvix/boot): use tvix-store copyFlorian Klink1-33/+6
Instead of using an additional Nix build producing a directory structure containing xz-compressed NAR files and NARInfos, and uploading these via `curl` to NAR-bridge, which then decomposes them and uploads them to tvix-store, have tvix-store interpret the exported reference graph directly, and deal with the uploading on its own.

This can be used in the future to boot proper NixOS VMs, which want a init= in their cmdline.

We don't have a OTLP collector inside the Nix build, this removes some noise from the log about not being able to reach it.

2024-03-18 r/7727 feat(tvix/boot): support seeding closures via nar-bridgeFlorian Klink1-42/+99
This updates the parameters mkBootTest can be called with. It now accepts a `path`, and then either importPathName needs to be set, or isClosure needs to be set to true. The former activates the existing functionality, tvix-store import is used to import contents as a NAR-addressed store path. The latter uploads the path as a closure (so including its references, and keeping the store paths intact) to tvix-store. We use nar-bridge, and the HTTP interface it provides to do this. As `nix copy` can't be used inside a Nix build, we use `pkgs.mkBinaryCache` to come up with the .narinfo and .nar files that would be in a binary cache, and then use a bit of GNU Parallel and bash to upload store paths ourselves.

2024-03-18 r/7725 feat(tvix/boot/tests): make urls and paths configurableFlorian Klink1-16/+39
Fork off a long-living tvix-store daemon in the background, and have both the import, as well as the virtiofs invocation connect to that one, rather than use the underlying storage directly. This also opens up the potential to have other things seed the store (like nar-bridge).
