The workspace is now host/ and vfs/. v2 crates leave the workspace as reference.
host/src/exec.rs is the contract between the process table and the harness.
The console reads a line, runs it to the end, and prints the result,
with and without a terminal. Notifications print while a command runs.
Ctrl-C during a command stops only the wait. 314 lines (was 480).
All host integration tests are modules of cli/tests/host/, so they run
in one parallel pool, and the probes build once. Warm, the 184 host
tests take 24 s (was about 45 s as seven binaries in sequence), and
cargo test --workspace takes 45 s.
128 fast activate/revert cycles are not a realistic load. restarts_service
covers the restart of a service after an upgrade. nix flake check runs
the normal tests only.
- The cargo target folder is <cache>/cargo-target, next to Wasmtime's
cache, which moves to <cache>/wasmtime: Wasmtime's cleanup worker
deletes unknown entries in its folder, also Cargo's artifacts.
- Builds use the SDK at <cache>/sdk/<content hash>/, so cargo reuses
the compiled SDK in every world. /plugins/cargo/sdk/ stays for agents.
- Tests run in the release profile and share compiled crates with the
release build.
- The cargo and cli tests use a persistent cache in CARGO_TARGET_TMPDIR:
warm, the cargo suite takes 11 s (was 235 s) and the cli suite 6 s
(was 149 s).
- nix flake check runs ignored stress tests. AGENTS.md: rules for fast
tests.
- flake: checks.tests = the sausage package with doCheck (tests of sausage,
sausage-actor, agent; fixtures build offline from vendored crates).
- .gitea/workflows/ci.yml: `nix flake check -L` on runner label `nixos`.
Not compiled: written by the Sausage agent.
Staging every write until close broke tempfile, git, and SQLite, which
expect normal files. Actors that need an atomic publish write a temporary
file and rename it; the SDK has write_atomic for that.
Host:
- test first: a new version is tested where it lies; only an installed
version goes to versions/, and instances run from there
- data/ and public/ are shared by all versions; no snapshots; rollback
restores code only
- no re-delivery, status.json, list, remove/archive, smoke test, data/
hiding, or stdin timeout; rollback needs a version
- supervisor.rs split out; one place for installing a version
- init only writes the agent folder; run installs it like any actor
- console: @actor, text to the agent, /help, /quit
Agent:
- every text goes out as a broadcast; 5-line prompt; 5 tools that describe
themselves; turn.json only marks an active turn
Docs: PROTOCOL.md, README.md, DECISIONS.md, AGENTS.md rewritten.
Examples: only notes and notes-v2.
