Adds ten `#[ignore]`'d integration tests in
backend/windmill-runtime-nativets/src/smoke_tests.rs exercising the JS
API surface that the existing nativets tests in tests/worker.rs don't
reach. Run them when bumping the deno_core / deno_ast / deno_runtime /
swc_* pins in backend/Cargo.toml, not on every CI:
cargo test -p windmill-runtime-nativets smoke -- --ignored
# skip network-dependent ones with `--skip smoke_net_`
Why here and not in tests/worker.rs:
windmill-runtime-nativets is the only consumer of the deno_core crate
in the workspace — ScriptLang::Deno spawns the external `deno` binary
via deno_executor.rs, while ScriptLang::Nativets is the only path that
loads the in-process V8 runtime. So a deno_core / deno_ast bump can
only break things downstream of this crate. Co-locating the smoke
tests with the runtime they exercise means they hit the right surface
directly, skip the entire job-queue / worker / API-server stack, and
run in <1s end-to-end (vs. ~30-60s per test for the worker-level
nativets tests).
The tests use the existing `PrewarmedIsolate::spawn` API (already
public for the dedicated-worker path), which gives a clean
"compile-TS → load module → execute main(args) → return JSON" entry
point with no DB or queue plumbing required.
Coverage:
- smoke_basic_value_passing — args binding + return marshaling
- smoke_transpile_enum_and_union — TS-specific syntax (enums,
discriminated unions, casts) through swc_ecma_parser / swc_ecma_ast
- smoke_set_timeout_and_promise_all — deno_web timer ops + V8
microtask drain order
- smoke_url_and_searchparams — deno_url surface
- smoke_web_blob_btoa_atob — deno_web Blob + base64 ops
- smoke_large_payload_roundtrip — 512 KB string in/out through the
op-table boundary
- smoke_error_propagation_with_message — thrown Error must surface
in PrewarmedResult::Err with original message
- smoke_concurrent_isolates — 8 isolates spawned in parallel from
the same tokio runtime; catches V8 isolate-setup races
- smoke_net_fetch_example_com — deno_fetch end-to-end against
example.com
- smoke_net_fetch_json_and_headers — deno_fetch with custom request
headers + Response.json() against httpbin.org/anything
`structuredClone` is not currently wired into the nativets global —
documented in the smoke_web_blob_btoa_atob test in case that ever
changes.
All ten tests pass locally against the current pinned versions
(deno_core 0.336.0 / deno_ast =0.44.0 / swc_common =0.37.5).
Windmill Backend
This folder holds all backend components, the src/ folder only contains files used to build the "root" binary.
Components
| name | description |
|---|---|
| windmill-api | The API server, exposing functionality to other components and the frontend |
| windmill-audit | Contains audit functionality, allowing different components to record important actions |
| windmill-common | Common code shared by all crates |
| windmill-queue | Contains job & flow queuing functionality, commonly written to by the API server and read from by workers |
| windmill-worker | The worker. Used to process and execute flows & jobs. |
| parsers | Contains code to parse signatures in different langauges. |
