From a64382a630e78b67840b11c7c1244a7f03f9ae62 Mon Sep 17 00:00:00 2001 From: Marko Vejnovic Date: Fri, 22 May 2026 06:43:26 +0000 Subject: [PATCH 01/62] docs: spec for hm Mission Control TUI Host-side ratatui-based TUI for hm run / dev / cloud build watch, designed to be the easiest and most screenshot-worthy way to run a Harmont deployment. Mission Control layout (animated DAG + gantt timeline + log pane + summary card), tachyonfx for subtle effects, NO_COLOR / non-TTY falls back to the existing human plugin. Single protocol-level addition: hm_build_event_emit host fn so the embedded cloud plugin can drive the host TUI from its WASM watch loop without lifting that loop out of the sandbox. --- .../2026-05-22-tui-mission-control-design.md | 461 ++++++++++++++++++ 1 file changed, 461 insertions(+) create mode 100644 docs/superpowers/specs/2026-05-22-tui-mission-control-design.md diff --git a/docs/superpowers/specs/2026-05-22-tui-mission-control-design.md b/docs/superpowers/specs/2026-05-22-tui-mission-control-design.md new file mode 100644 index 00000000..2981c97a --- /dev/null +++ b/docs/superpowers/specs/2026-05-22-tui-mission-control-design.md @@ -0,0 +1,461 @@ +# `hm` Mission Control TUI — Design + +**Status:** approved 2026-05-22 +**Owner:** marko@simci.dev +**Goal:** Replace the default plain-text TTY output of `hm run`, `hm dev up`, +and `hm cloud build watch` with a beautiful, animated, host-side TUI that +is the easiest and most screenshot-worthy way to run a Harmont deployment. + +The TUI is also the marketing surface — every frame is something a viewer +might quote-tweet, so engagement is a first-class non-functional requirement +alongside correctness and performance. + +--- + +## 1. Architecture + +### 1.1 Runtime placement + +The TUI lives **inside the `hm` binary** at `crates/hm/src/tui/`. It is not a +WASM output plugin. Rationale: + +- ratatui needs raw mode, the alternate screen, mouse capture, resize events, + and ideally 60fps frame submission. The existing `OutputFormatter` capability + is pure `on_event(BuildEvent)` running in an Extism sandbox with only + `hm_write_stdout` / `hm_write_stderr` host fns. Bridging that to ratatui + would require ~10 new host fns and would still pay a per-call WASM tax on + every animation frame. +- The WASM-plugin output path (`hm-plugin-output-human`, `hm-plugin-output-json`) + is **not removed**. It remains the non-TTY default and the `--format human` + / `--format json` opt-out. The new TUI is a third sibling, selected by TTY + detection. + +### 1.2 Event-source abstraction + +All three command surfaces feed the TUI through a single, typed channel: + +```rust +// crates/hm/src/tui/event.rs +pub enum TuiEvent { + BuildStart { run_id: Uuid, plan: PlanSummary, started_at: DateTime }, + ChainQueued { chain_idx: usize, label: String, parent: Option }, + StepStart { step_id: Uuid, chain_idx: usize, runner: String, image: Option, label: String }, + StepLog { step_id: Uuid, stream: StdStream, line: String, ts: DateTime }, + StepCacheHit { step_id: Uuid, key: String, tag: String }, + StepEnd { step_id: Uuid, exit_code: i32, duration_ms: u64 }, + ChainFailed { chain_idx: usize, failed_step_key: String, exit_code: i32, message: String }, + BuildEnd { exit_code: i32, duration_ms: u64 }, + + // dev-only + DeployStatus { deploy_id: String, label: String, state: DeployState, restarts: u32, uptime_ms: u64 }, + DeployLog { deploy_id: String, stream: StdStream, line: String, ts: DateTime }, +} + +pub enum DeployState { Starting, Healthy, Unhealthy, Restarting, Stopped } +``` + +`TuiEvent` is a **host-only** type. It is not on the plugin wire — wire types +stay in `hm-plugin-protocol` and remain frozen. The TUI translates inbound +data into `TuiEvent` at the adapter boundary so the rest of the TUI module +sees one event vocabulary. + +Three adapters live under `crates/hm/src/tui/source/`: + +- `local.rs` — subscribes via `orchestrator::events::Bus::subscribe()` (the + existing `tokio::sync::broadcast` used by the WASM output subscriber today) + and maps `BuildEvent → TuiEvent`. The mapping is 1:1 for build variants; + `Deploy*` variants are never emitted. +- `dev.rs` — wraps the dev daemon status source already used by `hm dev`. Ticks + on a 500ms interval; emits a `DeployStatus` per known deploy + tails each + deploy's log stream into `DeployLog`. `BuildStart` / `BuildEnd` are + synthesized at session begin / end with `chain_count = deploy_count`. +- `cloud.rs` — bridges the cloud watch loop, which today lives **inside the + `hm-plugin-cloud` WASM plugin** at + `crates/hm-plugin-cloud/src/verbs/build.rs::watch`. To route polled cloud + state into the host TUI without lifting the watch loop out of WASM, we + add one new host fn: `hm_build_event_emit(json_bytes) -> ()`. The payload + is a JSON-serialized wire `BuildEvent` (already defined in + `hm-plugin-protocol`, so the wire surface gains a transport channel but no + new types). The host implementation pushes the deserialized `BuildEvent` + into the same mpsc channel that `local.rs` uses, after the standard + `BuildEvent → TuiEvent` translation. The cloud plugin's `watch` calls + `hm_build_event_emit` once per state diff plus synthetic `BuildStart` / + `BuildEnd` bookends. This host fn is the only protocol-level addition + this design requires; it is also reusable by any future plugin that needs + to drive the host TUI from a poll/stream loop. + +### 1.3 Entry point + +```rust +// crates/hm/src/tui/mod.rs +pub async fn run( + mut events: mpsc::Receiver, + opts: TuiOptions, +) -> Result { /* … */ } + +pub struct TuiOptions { + pub fx_enabled: bool, + pub summary_card: bool, + pub title: String, // "hm run", "hm dev", "hm cloud build watch" +} +``` + +Each command's existing dispatch picks one of three paths: + +1. `--format json` → existing JSON plugin (unchanged). +2. `--format human` **or** non-TTY **or** `--no-tui` → existing human plugin + (unchanged). +3. Otherwise → `tui::run(...)`. + +The return value from `tui::run` is the build's exit code; the command propagates +it as today. + +### 1.4 Process lifecycle + +- On entry: enter the alternate screen, enable raw mode, enable mouse capture, + start a `tokio::time::interval(Duration::from_millis(16))` frame ticker. +- On exit (any path — success, error, Ctrl-C, panic): a single guard restores + the terminal in `Drop` (disable mouse, leave alt screen, disable raw mode, + show cursor). The guard is wrapped around the entire `tui::run` call so a + panic inside ratatui still restores the terminal before the panic message + prints. We additionally install a `std::panic::set_hook` that calls the + same restore function before delegating to the previous hook, so panics in + background tasks don't leave a broken terminal. +- Cancellation: `Ctrl-C` first asks the orchestrator to cancel (existing + `cancel.rs` channel); a second `Ctrl-C` within 2s exits immediately. + +--- + +## 2. UI Layout + +The TUI is a **fixed three-zone layout**. We deliberately do not ship a +window manager / movable panes — every screenshot looks the same shape, which +helps brand recognition. + +``` +┌─ HARMONT ──── run 4f2a · main · 00:42 ─ 3 chains · 2/9 done ─────┐ ← header (2 rows) +│ graph │ timeline │ +│ ●─┬─●─● │ c1 ████████████░░░░░ test 4.2s pass │ ← graph + timeline +│ ├─◆─● │ c2 ███████░░░░░░░░░░ build ⚡ 1.1s cache │ row, split 40/60 +│ └─◆ │ c3 ██░░░░░░░░░░░░░░░ lint 0.4s run │ (vertical: ~30%) +│ │ +│ log · c1 · test │ ← log pane +│ $ cargo test --workspace │ (remaining ~65%) +│ running 142 tests │ +│ test orchestrator::cache::hit … ok │ +│ … │ +└─ [tab] chain · [l] logs · [/] filter · [q] quit ─────────────────┘ ← footer (1 row) +``` + +### 2.1 Zones + +**Header (`widgets/header.rs`)** — 2 rows.

Print a one-line + notice on stderr. (This is a rare corner — most users don't resize during + a build — but the path exists so we never leave a broken render.) +- Otherwise: clear and re-layout. The layout is responsive — graph hides + if cols < 90; timeline labels truncate before chain rows hide. + +### 4.3 Non-build commands + +`hm version`, `hm plugin list`, etc. are unaffected. The TUI only attaches +to `run`, `dev up`, and `cloud build watch`. + +--- + +## 5. Testing and demo artifacts + +### 5.1 Layered tests + +- **Reducer tests** (`crates/hm/src/tui/app.rs` `#[cfg(test)] mod tests`) — + Pure-function tests of `AppState::apply(event) -> AppState`. No terminal, + no async. Covers: chain ordering, step status transitions, focus + invariants, log buffer ring, filter behavior. +- **Snapshot tests** (`crates/hm/tests/tui_snapshots.rs`) — Render the + ratatui `Frame` into a `Buffer`, serialize the buffer cells as text + style + per cell, snapshot with `insta`. Snapshots cover: empty state, one-chain + running, multi-chain with cache hit, one-chain failed, summary card + (pass), summary card (fail). +- **Resize tests** — feed a sequence of `Resize` events through the test + harness and snapshot the resulting frame at each. +- **No** end-to-end terminal tests in CI — those are flaky. Visual + regressions are caught by snapshots; the demo tape (next section) is the + human-eye check. + +### 5.2 Demo artifacts + +- `docs/demo/run.tape` — a [vhs](https://github.com/charmbracelet/vhs) tape + that runs `hm run` against `examples/rust/` and freezes on the summary + card. Committed alongside the generated `run.gif`. +- `docs/demo/dev.tape` — same for `hm dev up` against a small example. +- `docs/demo/cloud.tape` — same for `hm cloud build watch` (recorded against + a staging build; the tape ships a captured frame because the cloud API + isn't replayable). +- CI workflow `.github/workflows/demo.yml` — smoke-runs `run.tape` on PRs to + ensure the TUI still renders end-to-end. Does NOT fail on visual + differences (vhs is non-deterministic enough that we'd flake); only fails + if the tape errors out. + +The committed `run.gif` is what the README embeds and what every Twitter +post links to.

Their stdout is captured behind the alt-screen and + silently dropped while the TUI runs. We document this in the plugin + authoring guide and offer `hm_build_event_emit` as the migration path.

Allocates the same mpsc channel `scheduler::run` would create. -2. Stores it in `OrchestratorState` for the duration of the watch. -3. Spawns the TUI. -4. Invokes the cloud plugin's subcommand. - -**Files:** -- Modify: `crates/hm/src/dispatcher.rs` (or wherever the `cloud build watch` subcommand is dispatched to the cloud plugin) -- Add: a small `tui_session` helper in `crates/hm/src/tui/mod.rs` - -- [ ] **Step 1: Add the helper** - -In `crates/hm/src/tui/mod.rs`, append: - -```rust -/// Convenience: set up the host-fn TUI sink for a non-orchestrated -/// command (e.g., cloud build watch). Returns a guard that, when -/// dropped, clears the sink from `OrchestratorState`. -pub fn install_session_sink() -> (mpsc::Sender, mpsc::Receiver) { - let (bus_tx, bus_rx) = mpsc::channel(source::TUI_CHANNEL_CAPACITY); - let (tui_tx, tui_rx) = source::channel(); - - tokio::spawn(async move { - let mut bus_rx = bus_rx; - while let Some(ev) = bus_rx.recv().await { - let translated = source::local::translate_pub(ev); - if tui_tx.send(translated).await.is_err() { break; } - } - }); - - crate::orchestrator::state::install_tui_sink(bus_tx.clone()); - (bus_tx, tui_rx) -} -``` - -Expose `translate` from `local.rs` by renaming it `pub fn translate_pub`, or add a small `pub` re-export. (The mechanical detail is left to the implementer; the requirement is that `cloud.rs` and the session-sink helper share one translation impl.) - -Implement `install_tui_sink` in `crates/hm/src/orchestrator/state.rs`: - -```rust -pub fn install_tui_sink(tx: tokio::sync::mpsc::Sender) { - if let Some(state) = current() { - // OrchestratorState is constructed per scheduler::run; the - // cloud path installs a parallel state by hand. - let _ = state; - } - // For cloud sessions, install a thin OrchestratorState with only - // tui_event_tx populated. The remaining fields are unused by the - // cloud plugin (it does not call docker_*/archive_* host fns). - use std::sync::Arc; - use crate::orchestrator::events::EventBus; - use crate::orchestrator::archive::ArchiveStore; - use tokio_util::sync::CancellationToken; - use uuid::Uuid; - // Reuse `connect` lazily — if no docker, leave it un-set; the - // cloud watch path does not touch docker. - let docker = crate::orchestrator::docker_client::DockerClient::dummy(); - let state = Arc::new(OrchestratorState { - event_bus: EventBus::new(), - archives: ArchiveStore::new(), - cancel: CancellationToken::new(), - docker, - run_id: Uuid::new_v4(), - tui_event_tx: Some(tx), - }); - install(state); -} -``` - -> **Note:** `DockerClient::dummy()` is not a real constructor today. The implementer either (a) refactors `OrchestratorState` so the `docker` field is `Option` for non-build sessions, or (b) lazily connects to docker even for cloud watch (cheap if it's already running, no-op otherwise). Pick (a) — it is cleaner and matches the spec's "the cloud plugin does not call docker_* host fns". - -If you pick (a): - -```rust -pub struct OrchestratorState { - pub event_bus: EventBus, - pub archives: ArchiveStore, - pub cancel: CancellationToken, - pub docker: Option, - pub run_id: Uuid, - pub tui_event_tx: Option>, -} -``` - -…and update every consumer (`docker_host_fns.rs`) to handle `state.docker.as_ref().expect("docker not available")` or its equivalent. Each docker host-fn already runs only inside the orchestrator's local-run path, so this is a small ergonomic shift. - -- [ ] **Step 2: Branch the dispatcher** - -In `crates/hm/src/dispatcher.rs`, locate where `cloud` subcommands are forwarded to the plugin. Add a TTY-detect branch for the `cloud build watch` variant: - -```rust -use is_terminal::IsTerminal; - -let want_tui_for_cloud_watch = std::io::stdout().is_terminal() - && std::env::var("HM_NO_TUI").is_err() - && std::env::var("NO_COLOR").is_err(); - -if want_tui_for_cloud_watch && is_cloud_build_watch(&args) { - let (_bus_tx, tui_rx) = crate::tui::install_session_sink(); - let opts = crate::tui::TuiOptions { - fx_enabled: std::env::var("HM_NO_FX").is_err(), - summary_card: true, - title: "hm cloud build watch".into(), - }; - - let plugin_handle = tokio::spawn(async move { - // existing dispatch into the cloud plugin - dispatch_cloud_plugin(args).await - }); - let tui_exit = crate::tui::run(tui_rx, opts).await - .map_err(|e| anyhow::anyhow!(e))?; - let plugin_exit = plugin_handle.await??; - return Ok(if tui_exit != 0 { tui_exit } else { plugin_exit }); -} -``` - -`is_cloud_build_watch(&args)` is a helper that returns true when `args[0] == "cloud" && args[1] == "build" && args.contains(&"watch")` — adjust to the exact dispatcher shape. - -- [ ] **Step 3: Build + commit** - -```bash -cargo build -p hm -git add crates/hm/src/dispatcher.rs \ - crates/hm/src/orchestrator/state.rs \ - crates/hm/src/tui/mod.rs -git commit -m "feat(hm cloud build watch): TUI session sink + host-fn bridge" -``` - ---- - -## Phase 7 — Demo, CI, README - -### Task 7.1: vhs tape for `hm run` - -**Files:** -- Create: `docs/demo/run.tape` - -- [ ] **Step 1: Write the tape** - -Create `docs/demo/run.tape`: - -``` -Output docs/demo/run.gif - -Set FontSize 14 -Set Width 1200 -Set Height 720 -Set Theme "Catppuccin Mocha" - -Type "cd examples/rust" -Enter -Sleep 500ms -Type "hm run" -Enter -Sleep 30s -Screenshot docs/demo/run.png -``` - -- [ ] **Step 2: Generate locally** - -```bash -brew install vhs # or apt / cargo install — vhs install per Charm docs -vhs docs/demo/run.tape -``` - -Expected: `docs/demo/run.gif` and `docs/demo/run.png` produced. - -- [ ] **Step 3: Commit** - -```bash -git add docs/demo/run.tape docs/demo/run.gif docs/demo/run.png -git commit -m "docs(demo): vhs tape + GIF/PNG for hm run TUI" -``` - -### Task 7.2: README embed - -**Files:** -- Modify: `README.md` - -- [ ] **Step 1: Add the GIF** - -In `README.md`, immediately under the title (after the `[![license]]` shield), insert: - -```markdown -![hm run Mission Control TUI](docs/demo/run.gif) -``` - -- [ ] **Step 2: Commit** - -```bash -git add README.md -git commit -m "docs(readme): embed Mission Control TUI demo GIF" -``` - -### Task 7.3: vhs tape for `hm dev up` - -**Files:** -- Create: `docs/demo/dev.tape` - -- [ ] **Step 1: Write the tape** - -Create `docs/demo/dev.tape` mirroring Task 7.1 but invoking `hm dev up` against a simple example (use the smallest example that has a `@hm.deploy` decorator — pick one from `examples/`;

Implementer extends `TuiOptions` with `cancel: Option` if/when this becomes visible in the demo; otherwise the v1 single-Ctrl-C exit is acceptable. - -**Type consistency:** `TuiEvent` variant names and field names used in `app.rs`, `source/local.rs`, `widgets/*.rs`, and `tui/mod.rs` are all consistent. `OrchestratorState.tui_event_tx` is referenced from `host_fns.rs` and `scheduler.rs` with the same `Option>` type. `StepStatus` shared between `app.rs` reducer and `theme.rs` / widget files. - -**Scope check:** This is a single subsystem (the TUI module + adapters + one host fn + command wiring + demo).

Architecture - -### 1.1 Runtime placement - -The TUI lives **inside the `hm` binary** at `crates/hm/src/tui/`. It is not a -WASM output plugin. Rationale: - -- ratatui needs raw mode, the alternate screen, mouse capture, resize events, - and ideally 60fps frame submission. The existing `OutputFormatter` capability - is pure `on_event(BuildEvent)` running in an Extism sandbox with only - `hm_write_stdout` / `hm_write_stderr` host fns. Bridging that to ratatui - would require ~10 new host fns and would still pay a per-call WASM tax on - every animation frame. -- The WASM-plugin output path (`hm-plugin-output-human`, `hm-plugin-output-json`) - is **not removed**. It remains the non-TTY default and the `--format human` - / `--format json` opt-out. The new TUI is a third sibling, selected by TTY - detection. - -### 1.2 Event-source abstraction - -All three command surfaces feed the TUI through a single, typed channel: - -```rust -// crates/hm/src/tui/event.rs -pub enum TuiEvent { - BuildStart { run_id: Uuid, plan: PlanSummary, started_at: DateTime }, - ChainQueued { chain_idx: usize, label: String, parent: Option }, - StepStart { step_id: Uuid, chain_idx: usize, runner: String, image: Option, label: String }, - StepLog { step_id: Uuid, stream: StdStream, line: String, ts: DateTime }, - StepCacheHit { step_id: Uuid, key: String, tag: String }, - StepEnd { step_id: Uuid, exit_code: i32, duration_ms: u64 }, - ChainFailed { chain_idx: usize, failed_step_key: String, exit_code: i32, message: String }, - BuildEnd { exit_code: i32, duration_ms: u64 }, - - // dev-only - DeployStatus { deploy_id: String, label: String, state: DeployState, restarts: u32, uptime_ms: u64 }, - DeployLog { deploy_id: String, stream: StdStream, line: String, ts: DateTime }, -} - -pub enum DeployState { Starting, Healthy, Unhealthy, Restarting, Stopped } -``` - -`TuiEvent` is a **host-only** type. It is not on the plugin wire — wire types -stay in `hm-plugin-protocol` and remain frozen. The TUI translates inbound -data into `TuiEvent` at the adapter boundary so the rest of the TUI module -sees one event vocabulary. - -Three adapters live under `crates/hm/src/tui/source/`: - -- `local.rs` — subscribes via `orchestrator::events::Bus::subscribe()` (the - existing `tokio::sync::broadcast` used by the WASM output subscriber today) - and maps `BuildEvent → TuiEvent`. The mapping is 1:1 for build variants; - `Deploy*` variants are never emitted. -- `dev.rs` — wraps the dev daemon status source already used by `hm dev`. Ticks - on a 500ms interval; emits a `DeployStatus` per known deploy + tails each - deploy's log stream into `DeployLog`. `BuildStart` / `BuildEnd` are - synthesized at session begin / end with `chain_count = deploy_count`. -- `cloud.rs` — bridges the cloud watch loop, which today lives **inside the - `hm-plugin-cloud` WASM plugin** at - `crates/hm-plugin-cloud/src/verbs/build.rs::watch`. To route polled cloud - state into the host TUI without lifting the watch loop out of WASM, we - add one new host fn: `hm_build_event_emit(json_bytes) -> ()`. The payload - is a JSON-serialized wire `BuildEvent` (already defined in - `hm-plugin-protocol`, so the wire surface gains a transport channel but no - new types). The host implementation pushes the deserialized `BuildEvent` - into the same mpsc channel that `local.rs` uses, after the standard - `BuildEvent → TuiEvent` translation. The cloud plugin's `watch` calls - `hm_build_event_emit` once per state diff plus synthetic `BuildStart` / - `BuildEnd` bookends. This host fn is the only protocol-level addition - this design requires; it is also reusable by any future plugin that needs - to drive the host TUI from a poll/stream loop. - -### 1.3 Entry point - -```rust -// crates/hm/src/tui/mod.rs -pub async fn run( - mut events: mpsc::Receiver, - opts: TuiOptions, -) -> Result { /* … */ } - -pub struct TuiOptions { - pub fx_enabled: bool, - pub summary_card: bool, - pub title: String, // "hm run", "hm dev", "hm cloud build watch" -} -``` - -Each command's existing dispatch picks one of three paths: - -1. `--format json` → existing JSON plugin (unchanged). -2. `--format human` **or** non-TTY **or** `--no-tui` → existing human plugin - (unchanged). -3. Otherwise → `tui::run(...)`. - -The return value from `tui::run` is the build's exit code; the command propagates -it as today. - -### 1.4 Process lifecycle - -- On entry: enter the alternate screen, enable raw mode, enable mouse capture, - start a `tokio::time::interval(Duration::from_millis(16))` frame ticker. -- On exit (any path — success, error, Ctrl-C, panic): a single guard restores - the terminal in `Drop` (disable mouse, leave alt screen, disable raw mode, - show cursor). The guard is wrapped around the entire `tui::run` call so a - panic inside ratatui still restores the terminal before the panic message - prints. We additionally install a `std::panic::set_hook` that calls the - same restore function before delegating to the previous hook, so panics in - background tasks don't leave a broken terminal. -- Cancellation: `Ctrl-C` first asks the orchestrator to cancel (existing - `cancel.rs` channel); a second `Ctrl-C` within 2s exits immediately. - ---- - -## 2.

No spec requirement is unaddressed. +- **External output plugins:** the `OutputFormatter` SDK trait, the `Capability::OutputFormatter` variant, the `hm_output_on_event` capability export, and the registry-based fallback in `output_subscriber` all stay intact. External plugins keep working — the change is internal: built-ins skip the WASM path. +- **Tests:** every modified widget already has a snapshot test (`buffer_to_string`-based). The plan asks the engineer to run each before and after; if `insta` flags a diff, the engineer reviews visually before accepting. The output formatter logic is preserved verbatim (same `render` body for human; same `serde_json::to_vec` + newline for json), so existing unit tests transfer with the file. +- **Commits:** one commit per task, every task ends with a `git add` + `git commit`. DRY: per-widget tasks share the same `Block` / `Paragraph` skeleton but the code is repeated in each task because an engineer may execute them out of order.

Fixes the Docker Desktop on Linux paper cut: Desktop ships a 'desktop-linux' context pointing at ~/.docker/desktop/docker.sock, but bollard's connect_with_local_defaults only looks at /var/run/docker.sock, so `hm run` would bail on a Desktop host without an explicit DOCKER_HOST export.

Remote HTTPS contexts return a clear "not supported, set DOCKER_HOST" error rather than silently downgrading — bollard's ssl feature would pull rustls+ring transitively and isn't worth it for a niche case. --- crates/hm/src/orchestrator/docker_client.rs | 65 ++++- crates/hm/src/orchestrator/docker_context.rs | 239 +++++++++++++++++++ crates/hm/src/orchestrator/mod.rs | 1 + 3 files changed, 298 insertions(+), 7 deletions(-) create mode 100644 crates/hm/src/orchestrator/docker_context.rs diff --git a/crates/hm/src/orchestrator/docker_client.rs b/crates/hm/src/orchestrator/docker_client.rs index fc43071b..77ca4048 100644 --- a/crates/hm/src/orchestrator/docker_client.rs +++ b/crates/hm/src/orchestrator/docker_client.rs @@ -28,17 +28,68 @@ pub struct DockerClient { } impl DockerClient { - /// Open a Docker connection using the platform's default socket / - /// pipe.

charset=UTF-8 Content-Transfer-Encoding: 8bit The two plugin_kv tests each set XDG_CONFIG_HOME (process-global) to their own tempdir. Run in parallel — which CI does — they clobber each other's env var between set/read, producing intermittent None reads. Local repro is hard because higher parallelism on dev boxes still happens to interleave reads between the two writes; CI's lower vCPU count widened the window. Merge the two tests into one serialised body. No new dev-deps, no test-thread-counts pinning. --- crates/hm/src/plugin/host_fns.rs | 41 ++++++++++++++++---------------- 1 file changed, 20 insertions(+), 21 deletions(-) diff --git a/crates/hm/src/plugin/host_fns.rs b/crates/hm/src/plugin/host_fns.rs index 104d28c8..96f12a4f 100644 --- a/crates/hm/src/plugin/host_fns.rs +++ b/crates/hm/src/plugin/host_fns.rs @@ -1016,36 +1016,35 @@ pub(crate) fn current_step_id() -> Option { mod plugin_kv_tests { use super::*; + // Both round-trip and per-plugin-name isolation are covered by a + // single `#[test]` because `XDG_CONFIG_HOME` and + // `set_current_plugin_name` are *process-global*.
