From 90cd6bb74051706f194c081385061a6c36601a5a Mon Sep 17 00:00:00 2001 From: Marko Vejnovic Date: Sat, 23 May 2026 10:49:10 -0700 Subject: [PATCH 01/60] feat(sdk): define RawPlugin + RawHostApi stabby FFI traits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add stabby =72.1.1 and borsh 1 as workspace dependencies. Replace extism-pdk with stabby+borsh in hm-plugin-sdk. Define the two core FFI boundary traits (RawPlugin for plugin→host, RawHostApi for host→plugin) using #[stabby::stabby] with extern "C" + DynFuture for async methods. Compile-time assertions verify both traits produce valid stabby trait objects. --- Cargo.lock | 162 ++++++++++++++++++++++++-------- Cargo.toml | 2 + crates/hm-plugin-sdk/Cargo.toml | 5 +- crates/hm-plugin-sdk/src/ffi.rs | 39 ++++++++ crates/hm-plugin-sdk/src/lib.rs | 8 +- 5 files changed, 173 insertions(+), 43 deletions(-) create mode 100644 crates/hm-plugin-sdk/src/ffi.rs diff --git a/Cargo.lock b/Cargo.lock index 43ee1aa..8c5c465 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -194,7 +194,7 @@ checksum = "9035ad2d096bed7955a320ee7e2230574d28fd3c3a0f186cbea1ff3c7eed5dbb" dependencies = [ "proc-macro2", "quote", -

Key changes: - host.rs: LoadedPlugin now wraps stabby's Library + Dyn trait object instead of extism's PluginPool. Typed async methods (execute_step, on_hook_event, run_subcommand, on_output_event, finalize_output) replace the generic call_capability. - host_api.rs: New HostApiImpl struct implementing RawHostApi with all 11 FFI methods (log, kv_get/set, emit_event, emit_step_log, should_cancel, write_stdout/stderr, archive_read/total_size, fs_read_config). Minimal but compilable implementations. - registry.rs: Discovers .dylib/.so/.dll files instead of .wasm. Removed embedded/pool_sizes fields from RegistryConfig. Passes Arc to each LoadedPlugin::load(). - manifest.rs: Removed MissingHostFn variant and host-fn validation (no longer needed with stabby trait objects). - paths.rs: Changed user_plugins_dir to ~/.harmont/plugins/. - Deleted build.rs (no more WASM compilation at build time). - Deleted embedded.rs (no more include_bytes! embedding). Remaining errors are all caller-side (dispatcher.rs, scheduler.rs, output_subscriber.rs, install.rs) referencing the removed old API. Those callers will be updated in Tasks 5-8. --- Cargo.lock | 4 + crates/hm/Cargo.toml | 16 +- crates/hm/build.rs | 75 ------ crates/hm/src/plugin/embedded.rs | 21 -- crates/hm/src/plugin/host.rs | 444 +++++++++++++++++++++++-------- crates/hm/src/plugin/host_api.rs | 244 +++++++++++++++++ crates/hm/src/plugin/manifest.rs | 57 +--- crates/hm/src/plugin/mod.rs | 8 +- crates/hm/src/plugin/paths.rs | 11 +- crates/hm/src/plugin/registry.rs | 79 ++---- 10 files changed, 630 insertions(+), 329 deletions(-) delete mode 100644 crates/hm/build.rs delete mode 100644 crates/hm/src/plugin/embedded.rs create mode 100644 crates/hm/src/plugin/host_api.rs diff --git a/Cargo.lock b/Cargo.lock index 33953cc..8655868 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1560,6 +1560,7 @@ dependencies = [ "backon", "base64", "bollard", + "borsh", "bytes", "chrono", "clap", @@ -1574,8 +1575,10 @@ dependencies = [ "futures-util", "hex", "hm-plugin-protocol", + "hm-plugin-sdk", "ignore", "indicatif", + "libloading", "nix", "once_cell", "owo-colors", @@ -1588,6 +1591,7 @@ dependencies = [ "serde_json", "sha1", "sha2", + "stabby", "tar", "tempfile", "thiserror 2.0.18", diff --git a/crates/hm/Cargo.toml b/crates/hm/Cargo.toml index 97243c1..9bde7f7 100644 --- a/crates/hm/Cargo.toml +++ b/crates/hm/Cargo.toml @@ -8,18 +8,6 @@ description = "Command-line client for the Harmont CI platform." readme = "README.md" keywords = ["ci", "harmont", "cli"] categories = ["command-line-utilities", "development-tools"] -# Explicit include list: cargo's default ("everything tracked by git") -# would drop crates/hm/embedded/*.wasm (gitignored — they are CI-built -# artifacts, not source).

The `LifecycleHook::on_event` trait signature is updated to use a named lifetime `'a` (matching `StepExecutor` and `SubcommandPlugin`) so hook impls can use `ctx` in their async blocks. Keyring host-fn tests are removed from host-fn-probe since `RawHostApi` no longer exposes keyring operations. Test call sites updated to use new hyphenated crate names. --- Cargo.lock | 64 ++++++++++++- Cargo.toml | 7 +- crates/hm-fixtures/Cargo.toml | 50 ---------- crates/hm-fixtures/src/bin/host_fn_probe.rs | 94 ------------------- crates/hm-fixtures/src/bin/recording_hook.rs | 67 ------------- crates/hm-fixtures/src/lib.rs | 6 -- crates/hm-plugin-sdk/src/hook.rs | 8 +- crates/hm/tests/common/fixtures.rs | 57 ++++++----- crates/hm/tests/plugin_host_fns.rs | 4 +- crates/hm/tests/plugin_manifest.rs | 4 +- crates/hm/tests/plugin_registry.rs | 10 +- crates/hm/tests/runner_dispatch.rs | 2 +- tests/fixtures/bad-api-version/Cargo.toml | 21 +++++ .../fixtures/bad-api-version/src/lib.rs | 27 +++++- tests/fixtures/failing-subcommand/Cargo.toml | 21 +++++ .../fixtures/failing-subcommand/src/lib.rs | 24 +++-- tests/fixtures/freestyle-runner/Cargo.toml | 21 +++++ .../fixtures/freestyle-runner/src/lib.rs | 41 ++++---- tests/fixtures/host-fn-probe/Cargo.toml | 21 +++++ tests/fixtures/host-fn-probe/src/lib.rs | 84 +++++++++++++++++ tests/fixtures/noop-executor/Cargo.toml | 21 +++++ .../fixtures/noop-executor/src/lib.rs | 38 ++++---- tests/fixtures/recording-hook/Cargo.toml | 21 +++++ tests/fixtures/recording-hook/src/lib.rs | 74 +++++++++++++++ 24 files changed, 480 insertions(+), 307 deletions(-) delete mode 100644 crates/hm-fixtures/Cargo.toml delete mode 100644 crates/hm-fixtures/src/bin/host_fn_probe.rs delete mode 100644 crates/hm-fixtures/src/bin/recording_hook.rs delete mode 100644 crates/hm-fixtures/src/lib.rs create mode 100644 tests/fixtures/bad-api-version/Cargo.toml rename crates/hm-fixtures/src/bin/bad_api_version.rs => tests/fixtures/bad-api-version/src/lib.rs (54%) create mode 100644 tests/fixtures/failing-subcommand/Cargo.toml rename crates/hm-fixtures/src/bin/failing_subcommand.rs => tests/fixtures/failing-subcommand/src/lib.rs (67%) create mode 100644 tests/fixtures/freestyle-runner/Cargo.toml rename crates/hm-fixtures/src/bin/freestyle_runner.rs => tests/fixtures/freestyle-runner/src/lib.rs (59%) create mode 100644 tests/fixtures/host-fn-probe/Cargo.toml create mode 100644 tests/fixtures/host-fn-probe/src/lib.rs create mode 100644 tests/fixtures/noop-executor/Cargo.toml rename crates/hm-fixtures/src/bin/noop_executor.rs => tests/fixtures/noop-executor/src/lib.rs (55%) create mode 100644 tests/fixtures/recording-hook/Cargo.toml create mode 100644 tests/fixtures/recording-hook/src/lib.rs diff --git a/Cargo.lock b/Cargo.lock index 3752e45..30dbb06 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1153,13 +1153,75 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "7f24254aa9a54b5c858eaee2f5bccdb46aaf0e486a595ed5fd8f86ba55232a70" [[package]] -name = "hm-fixtures" +name = "hm-fixture-bad-api-version" version = "0.0.0" dependencies = [ + "hm-plugin-protocol", "hm-plugin-sdk", "semver", "serde", "serde_json", + "stabby", +] + +[[package]] +name = "hm-fixture-failing-subcommand" +version = "0.0.0" +dependencies = [ + "hm-plugin-protocol", + "hm-plugin-sdk", + "semver", + "serde", + "serde_json", + "stabby", +] + +[[package]] +name = "hm-fixture-freestyle-runner" +version = "0.0.0" +dependencies = [ + "hm-plugin-protocol", + "hm-plugin-sdk", + "semver", + "serde", + "serde_json", + "stabby", +] + +[[package]] +name = "hm-fixture-host-fn-probe" +version = "0.0.0" +dependencies = [ + "hm-plugin-protocol", + "hm-plugin-sdk", + "semver", + "serde", + "serde_json", + "stabby", +] + +[[package]] +name = "hm-fixture-noop-executor" +version = "0.0.0" +dependencies = [ + "hm-plugin-protocol", + "hm-plugin-sdk", + "semver", + "serde", + "serde_json", + "stabby", +] + +[[package]] +name = "hm-fixture-recording-hook" +version = "0.0.0" +dependencies = [ + "hm-plugin-protocol", + "hm-plugin-sdk", + "semver", + "serde", + "serde_json", + "stabby", ] [[package]] diff --git a/Cargo.toml b/Cargo.toml index e15dc9f..74780a2 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -9,7 +9,12 @@ members = [ "crates/hm-plugin-output-human", "crates/hm-plugin-output-json", "crates/hm-plugin-cloud", - "crates/hm-fixtures", + "tests/fixtures/noop-executor", + "tests/fixtures/recording-hook", + "tests/fixtures/failing-subcommand", + "tests/fixtures/host-fn-probe", + "tests/fixtures/bad-api-version", + "tests/fixtures/freestyle-runner", ] default-members = [ "crates/hm", diff --git a/crates/hm-fixtures/Cargo.toml b/crates/hm-fixtures/Cargo.toml deleted file mode 100644 index 07eda04..0000000 --- a/crates/hm-fixtures/Cargo.toml +++ /dev/null @@ -1,50 +0,0 @@ -[package] -name = "hm-fixtures" -version = "0.0.0" -publish = false -edition.workspace = true -license.workspace = true -repository.workspace = true -description = "Test fixtures (WASM plugins) for the hm crate.

Remove `required_host_fns` and `allowed_hosts` from PluginManifest (extism-era concepts; native plugins call APIs directly). Bump HM_PLUGIN_API_VERSION from 1 to 2. Delete dead files: docker_host_fns.rs (module decl already removed), hm-plugin-sdk/src/host.rs (extism host wrappers, never referenced by stabby SDK). Remove Docker schema snapshot tests and their .snap files. Update all 16 manifest construction sites across plugin crates, test fixtures, and host-side tests. --- crates/hm-plugin-cloud/src/lib.rs | 2 - crates/hm-plugin-docker/src/lib.rs | 2 - crates/hm-plugin-output-human/src/lib.rs | 2 - crates/hm-plugin-output-json/src/lib.rs | 2 - crates/hm-plugin-protocol/src/host_abi.rs | 107 -------- crates/hm-plugin-protocol/src/lib.rs | 8 +- crates/hm-plugin-protocol/src/manifest.rs | 12 +- crates/hm-plugin-protocol/tests/round_trip.rs | 2 - .../tests/schema_snapshots.rs | 24 +- .../schema_snapshots__docker_commit_args.snap | 22 -- .../schema_snapshots__docker_exec_args.snap | 44 --- ...schema_snapshots__docker_extract_args.snap | 27 -- .../schema_snapshots__docker_start_args.snap | 33 --- .../schema_snapshots__plugin_manifest.snap | 18 +- crates/hm-plugin-sdk/src/host.rs | 205 -------------- crates/hm-plugin-sdk/tests/hm_plugin_macro.rs | 2 - crates/hm/src/orchestrator/docker_host_fns.rs | 259 ------------------ crates/hm/src/plugin/manifest.rs | 4 - tests/fixtures/bad-api-version/src/lib.rs | 2 - tests/fixtures/failing-subcommand/src/lib.rs | 2 - tests/fixtures/freestyle-runner/src/lib.rs | 2 - tests/fixtures/host-fn-probe/src/lib.rs | 2 - tests/fixtures/noop-executor/src/lib.rs | 2 - tests/fixtures/recording-hook/src/lib.rs | 2 - 24 files changed, 5 insertions(+), 782 deletions(-) delete mode 100644 crates/hm-plugin-protocol/tests/snapshots/schema_snapshots__docker_commit_args.snap delete mode 100644 crates/hm-plugin-protocol/tests/snapshots/schema_snapshots__docker_exec_args.snap delete mode 100644 crates/hm-plugin-protocol/tests/snapshots/schema_snapshots__docker_extract_args.snap delete mode 100644 crates/hm-plugin-protocol/tests/snapshots/schema_snapshots__docker_start_args.snap delete mode 100644 crates/hm-plugin-sdk/src/host.rs delete mode 100644 crates/hm/src/orchestrator/docker_host_fns.rs diff --git a/crates/hm-plugin-cloud/src/lib.rs b/crates/hm-plugin-cloud/src/lib.rs index e655db9..4b1f544 100644 --- a/crates/hm-plugin-cloud/src/lib.rs +++ b/crates/hm-plugin-cloud/src/lib.rs @@ -54,9 +54,7 @@ hm_plugin!( args_schema: serde_json::json!({}), subcommands: vec![], })], - required_host_fns: vec![], config_schema: None, - allowed_hosts: vec![], }, subcommand = Cloud, ); diff --git a/crates/hm-plugin-docker/src/lib.rs b/crates/hm-plugin-docker/src/lib.rs index 5f1bb02..96b40e8 100644 --- a/crates/hm-plugin-docker/src/lib.rs +++ b/crates/hm-plugin-docker/src/lib.rs @@ -159,9 +159,7 @@ hm_plugin!( default: true, step_schema: None, })], - required_host_fns: vec![], config_schema: None, - allowed_hosts: vec![], }, executor = DockerExec, ); diff --git a/crates/hm-plugin-output-human/src/lib.rs b/crates/hm-plugin-output-human/src/lib.rs index afafc3e..e675f8b 100644 --- a/crates/hm-plugin-output-human/src/lib.rs +++ b/crates/hm-plugin-output-human/src/lib.rs @@ -46,9 +46,7 @@ hm_plugin!( name: "human".into(), mime: "text/plain".into(), })], - required_host_fns: vec![], config_schema: None, - allowed_hosts: vec![], }, output = Human, ); diff --git a/crates/hm-plugin-output-json/src/lib.rs b/crates/hm-plugin-output-json/src/lib.rs index 9f2ae78..3c5694e 100644 --- a/crates/hm-plugin-output-json/src/lib.rs +++ b/crates/hm-plugin-output-json/src/lib.rs @@ -46,9 +46,7 @@ hm_plugin!( name: "json".into(), mime: "application/x-ndjson".into(), })], - required_host_fns: vec![], config_schema: None, - allowed_hosts: vec![], }, output = Json, ); diff --git a/crates/hm-plugin-protocol/src/host_abi.rs b/crates/hm-plugin-protocol/src/host_abi.rs index aa016a6..b245ade 100644 --- a/crates/hm-plugin-protocol/src/host_abi.rs +++ b/crates/hm-plugin-protocol/src/host_abi.rs @@ -2,8 +2,6 @@ //!

The category() method maps the inner variants to the same ErrorCategory values as before. crates/hm/src/plugin/mod.rs is now a re-export shim; the six original module files are deleted. Integration tests in plugin_manifest.rs updated to downcast to RuntimeError directly. --- Cargo.lock | 1 + crates/hm/Cargo.toml | 1 + crates/hm/src/error.rs | 65 ++---- crates/hm/src/plugin/host.rs | 344 ----------------------------- crates/hm/src/plugin/host_api.rs | 246 --------------------- crates/hm/src/plugin/install.rs | 103 --------- crates/hm/src/plugin/manifest.rs | 127 ----------- crates/hm/src/plugin/mod.rs | 20 +- crates/hm/src/plugin/paths.rs | 41 ---- crates/hm/src/plugin/registry.rs | 196 ---------------- crates/hm/tests/plugin_manifest.rs | 12 +- 11 files changed, 30 insertions(+), 1126 deletions(-) delete mode 100644 crates/hm/src/plugin/host.rs delete mode 100644 crates/hm/src/plugin/host_api.rs delete mode 100644 crates/hm/src/plugin/install.rs delete mode 100644 crates/hm/src/plugin/manifest.rs delete mode 100644 crates/hm/src/plugin/paths.rs delete mode 100644 crates/hm/src/plugin/registry.rs diff --git a/Cargo.lock b/Cargo.lock index 9ac206f..568e532 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -1078,6 +1078,7 @@ dependencies = [ "futures-util", "hex", "hm-plugin-protocol", + "hm-plugin-runtime", "hm-plugin-sdk", "hm-util", "ignore", diff --git a/crates/hm/Cargo.toml b/crates/hm/Cargo.toml index 85a2cb2..9752add 100644 --- a/crates/hm/Cargo.toml +++ b/crates/hm/Cargo.toml @@ -57,6 +57,7 @@ hm-plugin-sdk = { workspace = true } stabby = { workspace = true } borsh = { workspace = true } libloading = "0.8" +hm-plugin-runtime = { workspace = true } hm-util = { workspace = true } schemars = { workspace = true } semver = { workspace = true } diff --git a/crates/hm/src/error.rs b/crates/hm/src/error.rs index 6a2d15f..4bed544 100644 --- a/crates/hm/src/error.rs +++ b/crates/hm/src/error.rs @@ -61,50 +61,8 @@ pub enum HmError { #[error("local scheduler error: {0}")] LocalScheduling(String), - #[error("plugin '{name}' failed to load from {path}: {reason}")] - PluginLoad { - name: String, - path: std::path::PathBuf, - reason: String, - doc_url: &'static str, - }, - - #[error("plugin '{name}': API version mismatch (plugin={found_api}, host={expected_api})")] - PluginManifest { - name: String, - expected_api: u32, - found_api: u32, - }, - - #[error( - "plugin '{name}': required host fn '{fn_name}' is unavailable (this hm build is too old; needs >= {min_hm_version})" - )] - PluginMissingHostFn { - name: String, - fn_name: String, - min_hm_version: semver::Version, - }, - - #[error("plugin '{name}' panicked during '{capability}': {message}")] - PluginPanic { - name: String, - capability: String, - message: String, - }, - - #[error("plugin '{name}' timed out after {after_ms}ms during '{capability}'")] - PluginTimeout { - name: String, - capability: String, - after_ms: u32, - }, - - #[error("plugin conflict: both '{plugin_a}' and '{plugin_b}' claim '{verb}'")] - PluginConflict { - verb: String, - plugin_a: String, - plugin_b: String, - }, + #[error(transparent)] + PluginRuntime(#[from] hm_plugin_runtime::error::RuntimeError), #[error( "step '{step_key}' requested runner '{runner}', but no plugin provides it (available: {available:?})" @@ -201,13 +159,18 @@ impl HmError { | Self::LocalScheduling(_) => ErrorCategory::Api, // Network: Network (reqwest), Docker (daemon unreachable) Self::Network(_) | Self::Docker(_) => ErrorCategory::Network, - // Plugin load failures (exit 5). - Self::PluginLoad { .. } - | Self::PluginManifest { .. } - | Self::PluginMissingHostFn { .. } - | Self::PluginConflict { .. } => ErrorCategory::PluginLoad, - // Plugin runtime failures (exit 6). - Self::PluginPanic { .. } | Self::PluginTimeout { .. } => ErrorCategory::PluginRuntime, + // Plugin failures — delegate categorisation to the inner enum. + Self::PluginRuntime(e) => { + use hm_plugin_runtime::error::RuntimeError; + match e { + RuntimeError::PluginLoad { .. } + | RuntimeError::PluginManifest { .. } + | RuntimeError::PluginMissingHostFn { .. } + | RuntimeError::PluginConflict { .. } => ErrorCategory::PluginLoad, + RuntimeError::PluginPanic { .. } + | RuntimeError::PluginTimeout { .. } => ErrorCategory::PluginRuntime, + } + } // Pipeline-level invalid config (exit 7).

Every capability call (execute_step, on_hook_event, run_subcommand) and the manifest export should pass typed structs directly across the ABI instead of serializing to JSON bytes. + +**Architecture:** The protocol crate's FFI modules (`executor.rs`, `subcommand.rs`, `error.rs`, `hook.rs`, `manifest.rs`, `host_abi.rs`) switch from `#[derive(Serialize, Deserialize)]` to `#[stabby::stabby]`. Host-internal types (`ir.rs` for Pipeline IR, `events.rs` for BuildEvent) stay serde — they never cross the FFI boundary. A new `value.rs` module provides `FfiValue`, a stabby-compatible dynamic value enum replacing `serde_json::Value`. The SDK crate provides a wrapper layer so plugin authors see std Rust types (String, Vec, BTreeMap) and never touch stabby types directly. The `RawPlugin` trait changes from byte-slice signatures to typed stabby signatures. The `hm_plugin!` macro drops serde_json entirely. + +**Tech Stack:** stabby v72.1.1 (`#[stabby::stabby]`, `#[repr(u8)]` for matchable enums, `stabby::string::String`, `stabby::vec::Vec`, `stabby::option::Option`, `stabby::collections::arc_btree::ArcBTreeMap`). + +**Conversion boundaries:** +- `ir::CommandStep` (serde) → `executor::CommandStep` (stabby): in orchestrator when building ExecutorInput +- `events::BuildEvent` (serde) → `hook::FfiBuildEvent` (stabby): in hook dispatcher +- `serde_json::Value` → `FfiValue`: in host when building SubcommandInput and ExecutorInput +- SDK types (std) ↔ protocol types (stabby): in macro-generated code + +--- + +### Task 1: Add stabby dependency to protocol crate and create FfiValue + +The protocol crate currently has no stabby dependency.

Update `CommandStep.runner_args` handling and any serde_json::Value usage. + +**Files:** +- Modify: `crates/hm/src/orchestrator/scheduler.rs` +- Modify: any other orchestrator files that build protocol types + +**Key changes:** + +1. `CommandStep.runner_args` is `Option` in `ir.rs` (unchanged) but `Option` in the executor's `CommandStep` (from `executor.rs`). When the orchestrator copies `ir::CommandStep.runner_args` into `executor::ExecutorInput`, convert: `.map(Value::from)`. + +Wait — `executor.rs`'s `CommandStep` IS `ir::CommandStep` (same type, re-exported). The `runner_args` field type change in executor.rs actually changes `ir::CommandStep` too since executor.rs imports from ir.rs. + +**Important:** `ir::CommandStep.runner_args` is `Option` and is deserialized from Python JSON. If we change it to `Value`, the serde deserialization from Python JSON won't work (Value doesn't have serde Deserialize... or does it? We could add serde derives to Value too). + +**Resolution:** Add `Serialize, Deserialize` to the `Value` enum in `value.rs`. Then `ir::CommandStep.runner_args: Option` can be deserialized from Python JSON via serde AND serialized via borsh for FFI. The `serde_json::Value` → `Value` conversion happens automatically during JSON deserialization. + +But wait — serde's JSON deserializer would need to know how to map JSON to our `Value` enum variants. By default, `#[derive(Deserialize)]` on an enum expects `{"Null": null}` or `{"Str": "hello"}` format, not raw JSON values. + +**Better approach:** Keep `ir::CommandStep.runner_args` as `serde_json::Value` in `ir.rs` (Python-facing). The executor's `ExecutorInput` construction converts: `runner_args: ir_step.runner_args.map(Value::from)`. This means `executor.rs`'s `CommandStep` already has `Value` but `ir.rs`'s `CommandStep` keeps `serde_json::Value`. + +Wait — currently `executor.rs` re-uses `ir::CommandStep` directly: +```rust +pub struct ExecutorInput { + pub step: CommandStep, // this IS ir::CommandStep + ... +} +``` + +So we can't change the type of `runner_args` in the ExecutorInput version without also changing it in ir.rs. Options: +1. Change both to `Value` (need custom serde for Value) +2. Keep `ir::CommandStep` as-is, make `executor.rs` define its own `ExecutorStep` struct (trimmed, with `Value`) +3. Add serde support to Value that mirrors serde_json::Value behavior + +Option 3 is actually the cleanest. Add `#[derive(Serialize, Deserialize)]` to Value with `#[serde(untagged)]` so it deserializes from raw JSON: +```rust +#[derive(Serialize, Deserialize, BorshSerialize, BorshDeserialize)] +#[serde(untagged)] +pub enum Value { + Null, + Bool(bool), + ... +} +``` + +With `#[serde(untagged)]`, serde tries each variant in order. But the order matters — `Int` vs `Float` vs `Bool`. Actually, serde's untagged deserialization tries variants in order. For JSON numbers, `i64` would be tried first, then `f64`. For `true`/`false`, `Bool` is tried. This should work. + +BUT: `#[serde(untagged)]` has edge cases. A JSON number `42` could be `Int(42)` or `Float(42.0)`. With ordered variants, `Int` is tried first — that's correct. A JSON number `3.14` fails `Int`, falls through to `Float` — correct. + +However, `Null` would match before anything. Actually, `#[serde(untagged)]` tries in variant order, so `Null` is tried first on every input. serde's `Null` variant only matches JSON `null`, so it correctly falls through. + +This approach lets us change `runner_args: Option` to `runner_args: Option` in `ir::CommandStep`. Python JSON deserialization still works. Borsh serialization also works.

serde_json serialization at the plugin FFI boundary with native `#[stabby::stabby]` types. Every capability call (execute_step, on_hook_event, run_subcommand) and the manifest export should pass typed structs directly across the ABI instead of serializing to JSON bytes. - -**Architecture:** The protocol crate's FFI modules (`executor.rs`, `subcommand.rs`, `error.rs`, `hook.rs`, `manifest.rs`, `host_abi.rs`) switch from `#[derive(Serialize, Deserialize)]` to `#[stabby::stabby]`. Host-internal types (`ir.rs` for Pipeline IR, `events.rs` for BuildEvent) stay serde — they never cross the FFI boundary. A new `value.rs` module provides `FfiValue`, a stabby-compatible dynamic value enum replacing `serde_json::Value`. The SDK crate provides a wrapper layer so plugin authors see std Rust types (String, Vec, BTreeMap) and never touch stabby types directly. The `RawPlugin` trait changes from byte-slice signatures to typed stabby signatures. The `hm_plugin!` macro drops serde_json entirely. - -**Tech Stack:** stabby v72.1.1 (`#[stabby::stabby]`, `#[repr(u8)]` for matchable enums, `stabby::string::String`, `stabby::vec::Vec`, `stabby::option::Option`, `stabby::collections::arc_btree::ArcBTreeMap`). - -**Conversion boundaries:** -- `ir::CommandStep` (serde) → `executor::CommandStep` (stabby): in orchestrator when building ExecutorInput -- `events::BuildEvent` (serde) → `hook::FfiBuildEvent` (stabby): in hook dispatcher -- `serde_json::Value` → `FfiValue`: in host when building SubcommandInput and ExecutorInput -- SDK types (std) ↔ protocol types (stabby): in macro-generated code - ---- - -### Task 1: Add stabby dependency to protocol crate and create FfiValue - -The protocol crate currently has no stabby dependency.

Same pattern for `on_hook_event()` and `run_subcommand()` — convert in, call trait, convert out. - -5. **Not-implemented stubs**: Return `PluginError` directly: -```rust -stabby::result::Result::Err( - hm_plugin_protocol::PluginError { - code: "not_implemented".into(), - message: "this plugin does not implement this capability".into(), - doc_url: stabby::option::Option::None(), - } -) -``` - -6. **`hm_load_plugin` entry point**: Construct `PluginManifest` (stabby) from the manifest expression. The manifest expression in user code currently evaluates to a protocol `PluginManifest`. Since protocol types are now stabby, this just works — the user's `PluginManifest { ... }` already constructs a stabby type (they use SDK re-exports which... hmm, SDK types are std-Rust now). - -**Important subtlety:** The `manifest = PluginManifest { ... }` expression in `hm_plugin!` invocation — which type is it? Currently it's `hm_plugin_protocol::PluginManifest` (accessible via `hm_plugin_sdk::PluginManifest` re-export). After the change: -- Protocol's `PluginManifest` is stabby -- SDK's `PluginManifest` is std-Rust -- Plugin code writes `hm_plugin_sdk::PluginManifest { ... }` (std types) -- The macro needs the protocol (stabby) version -- So the macro should convert: `let manifest: hm_plugin_protocol::PluginManifest = { #manifest_expr }.into();` - -This means the SDK's `PluginManifest` needs `Into`. - -7. **Delete `__ffi_bytes` helper** — no longer needed. - -8. **Remove `serde_json` from macro-generated code entirely.** The proc-macro crate itself doesn't depend on serde_json (it generates tokens that reference it).

But `plugin_static()` is still needed for the `&'static` lifetime on the stabby vtable. - -7. **Delete `ffi_err_to_anyhow`** — replace with direct field reads: -```rust -fn plugin_err_to_anyhow(name: &str, capability: &str, err: &hm_plugin_protocol::PluginError) -> anyhow::Error { - RuntimeError::PluginPanic { - name: name.to_string(), - capability: capability.to_string(), - message: err.message.to_string(), - }.into() -} -``` - -8. **Update callers**: The orchestrator's `scheduler.rs` constructs `ExecutorInput`. It currently builds the serde version.

Types come from `hm_plugin_sdk::*` (which now re-exports SDK types, not protocol types). Import paths don't change. - -2. Manifest construction: `PluginManifest { ... }` — fields are now std types (SDK wrapper), which the macro converts to stabby. String fields use `.into()`, `Vec` fields use `vec![...]`, `Option` fields use `None`/`Some(...)`. - -3.

Passes `&Value` to verb handlers. - -3. **Verb handlers**: Change `args: &serde_json::Value` to `args: &Value`. Accessors change: - - `args["field"].as_str()` → `args.get("field").and_then(Value::as_str)` - - `args["field"].as_i64()` → `args.get("field").and_then(Value::as_i64)` - - `args["field"].as_bool()` → `args.get("field").and_then(Value::as_bool)` - - These are slightly different APIs. The SDK `Value` should provide a `[]`-index operator (`impl Index<&str>`) for ergonomics, or verb helpers should be updated. - -4. **`manifest_schema.rs`**: `cloud_spec()` returns `SubcommandSpec`. This uses `spec_from_command()` from the SDK. That function returns protocol `SubcommandSpec` (now stabby). The manifest expression in `hm_plugin!` expects SDK `PluginManifest`. Need to bridge: `spec_from_command` should return SDK `SubcommandSpec`, or the manifest construction should convert. - - Best approach: `spec_from_clap::spec_from_command` returns SDK `SubcommandSpec` (std types).

If `repr(u8)` doesn't work with data-carrying variants, fall back to `repr(C)` or `repr(stabby)`. Test early in Task 2 with a simple enum: - -```rust -#[stabby::stabby] -#[repr(u8)] -enum Test { - A, - B { x: stabby::string::String }, - C(i32), -} -``` - -If this doesn't compile, all enums with data use `#[repr(C)]` instead (still allows standard `match` in most cases) or `#[repr(stabby)]` with `.match_*()` methods. - -## Risk: Recursive `FfiValue` - -`FfiValue::Array(Vec)` and `FfiValue::Object(ArcBTreeMap)` are recursive through heap indirection. Should compile fine — Vec and ArcBTreeMap are fixed-size pointer types. But verify in Task 1. - -## Risk: `forbid(unsafe_code)` in protocol crate - -`#[stabby::stabby]` derive may generate `unsafe` in its expansion. If protocol crate's `#![forbid(unsafe_code)]` blocks compilation, change to `#![deny(unsafe_code)]` with a module-level `#[allow(unsafe_code)]` on the modules that use stabby derives. diff --git a/tests/fixtures/bad-api-version/Cargo.toml b/tests/fixtures/bad-api-version/Cargo.toml index ea32a3b..3723571 100644 --- a/tests/fixtures/bad-api-version/Cargo.toml +++ b/tests/fixtures/bad-api-version/Cargo.toml @@ -15,7 +15,6 @@ hm-plugin-protocol = { workspace = true } stabby = { workspace = true } borsh = { workspace = true } serde = { workspace = true } -serde_json = { workspace = true } semver = { workspace = true } [lints] diff --git a/tests/fixtures/failing-subcommand/Cargo.toml b/tests/fixtures/failing-subcommand/Cargo.toml index 9ba74bd..ac520f3 100644 --- a/tests/fixtures/failing-subcommand/Cargo.toml +++ b/tests/fixtures/failing-subcommand/Cargo.toml @@ -15,7 +15,6 @@ hm-plugin-protocol = { workspace = true } stabby = { workspace = true } borsh = { workspace = true } serde = { workspace = true } -serde_json = { workspace = true } semver = { workspace = true } [lints] diff --git a/tests/fixtures/freestyle-runner/Cargo.toml b/tests/fixtures/freestyle-runner/Cargo.toml index 3df8897..253f4e7 100644 --- a/tests/fixtures/freestyle-runner/Cargo.toml +++ b/tests/fixtures/freestyle-runner/Cargo.toml @@ -15,7 +15,6 @@ hm-plugin-protocol = { workspace = true } stabby = { workspace = true } borsh = { workspace = true } serde = { workspace = true } -serde_json = { workspace = true } semver = { workspace = true } [lints] diff --git a/tests/fixtures/recording-hook/Cargo.toml b/tests/fixtures/recording-hook/Cargo.toml index 4b333e7..02f7864 100644 --- a/tests/fixtures/recording-hook/Cargo.toml +++ b/tests/fixtures/recording-hook/Cargo.toml @@ -15,7 +15,6 @@ hm-plugin-protocol = { workspace = true } stabby = { workspace = true } borsh = { workspace = true } serde = { workspace = true } -serde_json = { workspace = true } semver = { workspace = true } [lints]
