# Description of Changes Recently, my hacked-together env stopped working, probably due to our switching linkers. This pushed me to write a proper Nix packaging for SpacetimeDB, complete with flake and development environment. Some things I haven't been able to figure out (or in some cases, just haven't bothered with): - Unreal. - C# WASI SDK. - Exposing Git commit hash for `spacetime --version`. - Making the Rust SDK's reauth test work. This test tries to write a file in the home directory, which is inaccessible in the Nix sandbox. # API and ABI breaking changes It's a new thing we have to maintain if we're exposing it to users, but I need to maintain it anyways to be able to develop Spacetime, so... # Expected complexity level and risk 1 # Testing - [x] Ran `nix flake check` locally. - [x] Ran `nix build` locally and then did `spacetime start`, got an apparently-responsive SpacetimeDB. - [x] Ran `nix develop` locally, then `cargo build` and `cargo test` in the dev shell. --------- Co-authored-by: Jeffrey Dallatezza <jeffreydallatezza@gmail.com>

# Fetches a pre-built v8 build from GitHub.

# rusty_v8 is a bad citizen: it attempts to download a binary within its build.rs.
|
|
# When running in the Nix sandbox, this download fails, so the crate cannot build.
|
|
# We instead download the archive ahead of time using a Nix-friendly fetcher function,
|
|
# and in our flake.nix we'll reference it in an appropriate env var so the crate build finds it.
