Even a synchronous Rust function called from Dart executes off the main isolate — the UI thread is never blocked. For a generation that takes minutes, this is the critical guarantee. + +**FRB2 threading model:** +- Dart main isolate → spawns worker isolate(s) via FRB runtime +- Rust function executes on worker → sends result back to main isolate when done +- The C++ backend (stable-diffusion.cpp) is single-threaded per context and uses the `n_threads` param for sampling parallelism internally — this is orthogonal to FRB's isolate model + +**For the GUI:** `generate_image_stream` is a Rust function returning `StreamSink`. FRB2 converts this to a Dart `Stream`. The Dart `GenerationNotifier` subscribes to this stream and updates UI state on each event. + +--- + +## Progress Callback Pattern + +**Problem:** The existing `gen_img_with_progress` takes an `mpsc::Sender` (push model, Rust-internal channel). FRB2 uses `StreamSink` (pull model, Dart-managed stream). `Progress` fields (`step`, `steps`, `time`) are private. + +**Solution in the bridge crate (`gui/rust/src/lib.rs`):** + +```rust +// New public type for FRB2 (Progress fields are private in diffusion-rs) +pub struct ProgressEvent { + pub step: i32, + pub steps: i32, + pub time_per_step: f32, +} + +// FRB2 sees StreamSink and generates a Dart Stream +pub fn generate_image_stream(params: GuiParams, sink: StreamSink) { + std::thread::spawn(move || { + let (tx, rx) = std::sync::mpsc::channel::(); + + // Build Config and ModelConfig from GuiParams (see Data Flow below) + let (config, mut model_config) = params.into_configs().unwrap(); + + // Run blocking generation in a nested thread + let gen_handle = std::thread::spawn(move || { + diffusion_rs::api::gen_img_with_progress(&config, &mut model_config, tx) + }); + + // Forward progress events to Dart + for progress in rx { + sink.add(ProgressEvent { + step: progress.step(), // NOTE: needs getters added to Progress, or bridge + steps: progress.steps(), // uses a fork/patch of diffusion-rs + time_per_step: progress.time(), + }); + } + + gen_handle.join().unwrap().unwrap(); + // StreamSink closes automatically when function returns + }); +} +``` + +**Important constraint:** `Progress` struct fields are currently private in `src/api.rs`. Two options: +1. **Preferred:** Add `pub` to `step`, `steps`, `time` fields in `Progress` (one-line change to the Rust library, safe and non-breaking). +2. **Alternative:** Add `pub fn step(&self) -> i32`, etc. as accessor methods. + +Do not fork the library. Make the minimal upstream change. + +--- + +## Preview Image Pattern + +**How previews work in the existing Rust API:** + +`sd_set_preview_callback` is called with a C callback (`save_preview_local`) that writes the intermediate image to a `PathBuf`. The path is set via `config.preview_output(path)`. + +**For the GUI:** + +1. Before generation starts, the `RustGenerationService` creates a temp file path in the app temp dir: `$TEMP/diffusion_gui_/preview.png`. +2. This path is embedded in `GuiParams` and passed to the Rust bridge. +3. The bridge sets `config.preview_output(preview_path)`. +4. The `ProgressEvent` does NOT carry image bytes — it only carries `step/steps/time`. +5. The Dart `RightPanel` uses a `FileImage` widget that re-reads the preview file on each `ProgressEvent` using a `Key(progress.step)` to force Flutter to re-read from disk. +6. On generation complete, the final image path is returned (also in temp dir), and the Save button copies it to the user-chosen location. + +This avoids serializing image bytes over the FFI boundary on every step (which would be expensive for large images). + +--- + +## Mock Service Pattern + +**Why this is the right approach:** + +The Rust build (with CMake, C++ compilation, GPU backend) takes 5–20 minutes and requires GPU toolchains. Coupling UI development to Rust build cycles would destroy iteration speed. The service interface seam allows full UI development with zero Rust dependency. + +**MockGenerationService:** + +```dart +class MockGenerationService implements GenerationService { + @override + Stream generate(GenerationParams params) async* { + const totalSteps = 20; + for (int step = 1; step <= totalSteps; step++) { + await Future.delayed(const Duration(milliseconds: 200)); + yield ProgressEvent(step: step, steps: totalSteps, timePerStep: 0.2); + } + // Copy placeholder PNG to temp path + yield CompletionEvent(imagePath: await _writePlaceholder()); + } + + @override + Future> getAvailablePresets() async => + PresetData.allPresets; // hardcoded from CLI reference + + @override + Future> getWeightsForPreset(String preset) async => + PresetData.weightsFor(preset); // hardcoded lookup table +} +``` + +**Phase 1 → Phase 2 switch:** + +Change one line in the provider file: + +```dart +// Phase 1: +GenerationService generationService(Ref ref) => MockGenerationService(); + +// Phase 2: +GenerationService generationService(Ref ref) => + RustGenerationService(tempDir: ref.read(tempDirProvider)); +``` + +All UI code, all providers, all tests remain unchanged. + +--- + +## Two-Panel Layout: Resizable Split + +**Package: `multi_split_view` (pub.dev)** + +Use `MultiSplitView` with two children (left panel, right panel) and a `MultiSplitViewController` to set initial weight (e.g. 40% / 60%). The divider is drag-resizable out of the box. + +```dart +MultiSplitViewTheme( + data: MultiSplitViewThemeData(dividerThickness: 4), + child: MultiSplitView( + controller: MultiSplitViewController( + areas: [Area(weight: 0.4), Area(weight: 0.6)], + ), + children: [LeftPanel(), RightPanel()], + ), +) +``` + +**Alternative:** `split_view` or a raw `Row` with a `GestureDetector` on a vertical line. `multi_split_view` is preferred because it handles minimum area constraints and persists the split position. + +--- + +## Rust Bridge Crate Structure + +The bridge lives in `gui/rust/` as a separate Cargo crate (not as a workspace member of the root workspace — it is the Flutter project's native Rust code managed by FRB's `flutter_rust_bridge_codegen` tool). + +``` +gui/ + rust/ + Cargo.toml # crate-type = ["cdylib", "staticlib"] + src/ + lib.rs # FRB-annotated public API + params.rs # GuiParams struct, into_configs() conversion + presets.rs # get_presets(), get_weights_for_preset() + frb_generated.rs # auto-generated by flutter_rust_bridge_codegen +``` + +**`gui/rust/Cargo.toml`:** + +```toml +[package] +name = "diffusion-rs-gui" +version = "0.1.0" +edition = "2021" + +[lib] +crate-type = ["cdylib", "staticlib"] + +[dependencies] +diffusion-rs = { path = "../..", version = "0.1.20" } +flutter_rust_bridge = "2" +``` + +**Key design constraint:** This bridge crate must NOT pull in the diffusion-rs GPU features at compile time unless the build script activates them. The FRB codegen tool (`flutter_rust_bridge_codegen generate`) introspects the Rust source without building the C++ backend — this requires the GPU backends to be feature-gated behind `#[cfg(feature = "cuda")]` etc., which diffusion-rs already does correctly. + +--- + +## Rust Bridge API Surface + +What the bridge crate exposes to Dart (public FRB-annotated functions): + +```rust +// Preset/weight discovery (called once at startup) +pub fn get_presets() -> Vec +pub fn get_weights_for_preset(preset: String) -> Vec +pub fn preset_supports_weights(preset: String) -> bool + +// Generation (returns via StreamSink — Dart sees this as Stream) +pub fn generate_image_stream(params: GuiParams, sink: StreamSink) + +// Types +pub struct GuiParams { + pub preset: String, + pub weights: Option, + pub prompt: String, + pub negative: Option, + pub steps: Option, + pub width: Option, + pub height: Option, + pub batch: u32, + pub output_dir: String, // always the app temp dir + pub preview_path: String, // temp file for preview PNG + pub cache: Option, + pub preview: Option, + pub upscaler: Option, + pub upscaler_scale: f32, + pub token: Option, + pub low_vram: bool, + pub seed: i64, +} + +pub struct ProgressEvent { + pub step: i32, + pub steps: i32, + pub time_per_step: f32, + pub preview_path: Option, // set when a new preview PNG was written +} +``` + +The `params.rs` module converts `GuiParams` into `(Config, ModelConfig)` using diffusion-rs builders, mirroring what `cli/src/main.rs` does.

If called without FRB's isolate mechanism (e.g. via dart:ffi directly), the UI freezes. +**Instead:** Always go through the FRB bridge. FRB's worker isolate handles thread safety. + +### Anti-Pattern 2: One Riverpod provider per form field +**What goes wrong:** 15 separate providers for 15 form fields. Every field change triggers a broad rebuild. Cross-field validation (upscaler requires cache) requires reading 2+ providers in a notifier, creating implicit dependencies that are hard to test. +**Instead:** One `GenerationParams` value class with all fields, one `GenerationParamsNotifier`. All validation lives in one place. + +### Anti-Pattern 3: Passing image bytes over FFI for every preview step +**What goes wrong:** SDXL at 1024x1024 = 3MB RGB per preview frame. At 20 steps, that is 60MB serialized over FFI. Causes latency spikes and GC pressure in Dart. +**Instead:** Write preview PNG to a temp file path (which the Rust C callback already does), and reload from disk in Flutter using `FileImage` with a step-keyed `Key` to invalidate the cache. + +### Anti-Pattern 4: Making the bridge crate a workspace member of the root Cargo workspace +**What goes wrong:** FRB's codegen tool expects a standalone crate it can build without activating GPU features. If the GUI bridge is pulled into the root workspace, cargo will try to compile stable-diffusion.cpp (which takes 20+ minutes and requires CUDA/Metal) every time FRB regenerates bindings. +**Instead:** `gui/rust/` is its own isolated Cargo workspace (`[workspace]` in its own `Cargo.toml`), excluded from the root workspace. The dependency on diffusion-rs uses a path reference. + +### Anti-Pattern 5: Hardcoding preset/weight lists in Dart +**What goes wrong:** The Rust library adds a new preset, and the Dart mock list is stale. The dropdown shows old presets in Phase 1 and correct presets in Phase 2 — inconsistency undermines testing. +**Instead:** Even in Phase 1, derive the mock's preset list from a single Dart constant file (`preset_data.dart`) that is manually synced from the Rust `Preset` enum. In Phase 2, query the bridge's `get_presets()` at startup. Keep the two in sync via a comment linking to the Rust source. + +### Anti-Pattern 6: Forgetting to clean the temp dir on app exit +**What goes wrong:** Each generation writes 1–10 MB of PNG files to temp. After 100 runs, several hundred MB accumulate. +**Instead:** `TempDirManager` registers a `WidgetsBindingObserver` and deletes the session temp dir in `didRequestAppExit()`. Also run cleanup at startup to catch any leftover dirs from crashes. + +--- + +## Scalability Considerations + +| Concern | Current scope (v1) | Notes | +|---------|-------------------|-------| +| Concurrent generations | One at a time (by design) | ModelConfig holds mutable sd_ctx; concurrent calls would corrupt state. FRB bridge must enforce single-call semantics via a Mutex or by checking isRunning before starting. | +| Multiple output images (batch > 1) | Supported in Rust | GUI should display all batch images in RightPanel (scrollable list). | +| Large model loading (first run) | Model is loaded lazily on first gen_img call | The bridge can emit a "loading model" progress phase before the diffusion steps begin. | +| App restart with preserved settings | Not in scope for v1 | SharedPreferences can persist GenerationParams easily when needed. | + +--- + +## Suggested Build Order + +Build in this sequence to validate assumptions earliest and defer the hardest integration work: + +1. **Flutter project scaffold** — `flutter create gui`, add dependencies (Riverpod, multi_split_view, Yaru), configure desktop targets. +2. **GenerationParams value class + MockGenerationService** — pure Dart, no Rust, no UI.

If the Rust function is declared as a plain (non-async) function, the bridge calls it synchronously on the calling Dart isolate. For a generation that takes 30–300 seconds, this completely freezes the Flutter UI — no repaints, no button response, no progress bar updates — until the Rust function returns. The UI is dead, not just slow. + +**Why it happens:** Developers new to flutter_rust_bridge assume "the bridge handles threading." It does for `async` Rust functions, which are dispatched to a Dart isolate automatically. But sync Rust functions are not. The diffusion-rs API (`generate()`, `upscale()`) are synchronous blocking calls. + +**Consequences:** App appears frozen/crashed. On macOS, the OS may show the spinning beach ball and offer to force-quit. On Windows, the window stops responding and gets a "not responding" title. Users lose trust. + +**Prevention:** +- Wrap every long-running Rust call in a `Future.run()` / `compute()` or ensure the bridge function is declared `async` on the Dart side. +- With flutter_rust_bridge v2, annotate long-running Rust functions with `#[frb(sync = false)]` (the default for `async fn`) or expose them as `async fn` in Rust using Tokio/blocking spawn internally. +- Verify in Phase 2 (wiring) by adding a timer widget — if it stops ticking, the main isolate is blocked. + +**Warning signs:** +- Progress bar widget stops animating during generation. +- `flutter run` console shows "I/flutter: Skipped N frames" or ANR-style warnings. +- The Start button cannot be clicked again even to cancel. + +**Phase that must address it:** Phase 2 (FFI wiring). Phase 1 (mock) is safe because mock progress uses `Future.delayed`. + +--- + +### Pitfall C-2: Rust Panic Propagating Across the FFI Boundary + +**What goes wrong:** Rust panics that cross an `extern "C"` FFI boundary are **undefined behavior**. With the existing codebase's 40+ `.unwrap()` calls (see CONCERNS.md), any unexpected input — non-UTF-8 path, poisoned `RwLock`, missing LoRA file — can trigger a panic inside the C-callable function. In Rust before edition 2024 stable with `-C panic=abort`, the default is `panic=unwind`, but unwinding across FFI is UB and will corrupt the Dart VM heap, causing a silent crash with no error message in the Flutter UI. + +**Why it happens:** The diffusion-rs library was designed as a CLI tool. Panics are acceptable in CLI context (process exits cleanly). Via FFI, the same panics become heap corruption. + +**Consequences:** App crashes silently with no error shown to the user. The crash may be non-deterministic (depends on whether the panic unwinds through the FFI boundary or aborts). On macOS/Linux, this manifests as SIGABRT or SIGSEGV with a cryptic backtrace. On Windows, it is an access violation. + +**Prevention:** +- Compile the Rust library with `panic = "abort"` in `[profile.release]` of the GUI crate's `Cargo.toml`. This converts panics to clean process aborts rather than UB heap corruption. The app will still crash, but predictably. +- Wrap every top-level FFI-exposed function in `std::panic::catch_unwind()` and return an error code instead of panicking. +- In Phase 2, add a `catch_unwind` wrapper around the flutter_rust_bridge entry points that calls the diffusion-rs API. The bridge itself cannot protect you from panics inside your Rust code. +- Long-term: fix the underlying `.unwrap()` calls in diffusion-rs (tracked in CONCERNS.md). + +**Warning signs:** +- App disappears without an error dialog when attempting generation. +- Console shows `signal: 6, SIGABRT` or similar. +- Inconsistent crashes (sometimes works, sometimes not) — hallmark of UB. + +**Phase that must address it:** Phase 2 (FFI wiring) — must add `catch_unwind` wrappers before any user testing. + +--- + +### Pitfall C-3: Progress Callback Threading — Calling Dart from a Non-Dart Thread + +**What goes wrong:** The diffusion-rs progress and preview callbacks (`unsafe extern "C"` at `src/api.rs:1513` and `src/api.rs:1540`) fire from a C++ thread that is NOT the Dart main isolate thread. When flutter_rust_bridge forwards these as `StreamSink` events, it must post to the Dart event loop. If the `StreamSink` is used incorrectly (e.g., accessed from the wrong thread, or dropped before the stream is consumed), the app crashes or the callback silently fires into the void. + +**Why it happens:** Developers assume the callback is called from the Rust async runtime, which the bridge manages. But these callbacks come from C++ (stable-diffusion.cpp's thread pool) via the `unsafe extern "C"` boundary — they are on a raw OS thread with no Dart VM attachment. + +**Consequences:** +- Crash with "Bad state: Stream has already been listened to" or "Null check operator used on a null value." +- Progress bar never updates (events lost). +- Dart heap corruption if the StreamSink is used after the Dart isolate has been torn down. + +**Prevention:** +- Use `StreamSink` from flutter_rust_bridge v2 — it is thread-safe by design and queues events to the correct Dart port. +- Never store a raw Dart port or callback pointer in C++ code; always go through the bridge's managed channel. +- On the Dart side, always `cancel()` the stream subscription before disposing the widget, not after. +- Set up stream early (before calling generate) so no events are lost in the window between function call and listener attachment. + +**Warning signs:** +- Progress events arrive in batches (buffer filling up) rather than smoothly. +- Debug console shows "Bad state" or "Broken pipe" when stream is done. +- Preview image never updates despite progress firing. + +**Phase that must address it:** Phase 2 (FFI wiring). In Phase 1, simulate with a `Stream.periodic` to validate the UI wiring pattern before real callbacks. + +--- + +### Pitfall C-4: Codegen Out of Sync — Generated Bridge Code Not Matching Rust API + +**What goes wrong:** flutter_rust_bridge v2 generates Dart binding code (`frb_generated.dart`) and Rust glue code (`frb_generated.rs`) from the Rust source. If the Rust API changes (function signature, new type, removed function) but the codegen is not re-run, the mismatch causes one of: (a) compile error in Rust, (b) `MissingPluginException` or symbol-not-found at runtime, or (c) type mismatch panic in the bridge layer. + +**Why it happens:** The codegen step is an explicit manual step (`flutter_rust_bridge_codegen generate`) that is easy to forget. In a monorepo where developers edit the Rust library and the Flutter GUI in the same commit, the codegen is often the forgotten third step. + +**Consequences:** The app builds but crashes at first bridge call. Or worse — it silently uses stale generated code and calls the wrong function signature. + +**Prevention:** +- Add codegen to the Rust library's `build.rs` so `cargo build` in the GUI crate re-runs codegen automatically. (`flutter_rust_bridge_codegen_build` crate provides this.) +- Add a CI check: run codegen, then `git diff --exit-code` on the generated files. If they drift, the CI fails. +- In the monorepo, document the exact build sequence: `cargo build -p diffusion-rs-gui` triggers codegen; `flutter pub get` + `flutter build` follows. + +**Warning signs:** +- `flutter run` succeeds but first bridge call throws `MissingPluginException`. +- Error message: "symbol not found: frb_dart_fn_deliver_output". +- Compilation succeeds but function arity mismatches at runtime. + +**Phase that must address it:** Phase 2 (FFI wiring) setup — the very first task is establishing the codegen pipeline reliably before writing any bridge logic. + +--- + +## Moderate Pitfalls + +--- + +### Pitfall M-1: Cargo Workspace + Flutter Subfolder — Linking and Artifact Location + +**What goes wrong:** When the Flutter app lives in `/gui` inside the diffusion-rs Cargo workspace, `flutter build` does not know where `cargo build` put the compiled `.dylib`/`.so`/`.dll`. The flutter_rust_bridge template assumes the Rust crate IS the Flutter project root's `rust/` subdirectory. When the structure diverges (workspace root above Flutter root), the `cargoKit` or manual build script must be explicitly told the artifact path. + +**Why it happens:** flutter_rust_bridge v2 uses `cargokit` for the native build integration. `cargokit` reads `pubspec.yaml` to find the Rust crate. If the Flutter `pubspec.yaml` is at `/gui/pubspec.yaml` but the Cargo workspace is at `/Cargo.toml`, the relative path `../` must be correctly specified in `pubspec.yaml`'s `flutter_rust_bridge` section. + +**Consequences:** +- `flutter build` succeeds but does not embed the native library — app starts, then crashes with "Failed to load dynamic library." +- On macOS, the `.dylib` ends up in `target/` but is not copied to `macos/Runner/Frameworks/`. +- On Windows, the `.dll` is not placed alongside the `.exe`. + +**Prevention:** +- Set `crate-type = ["cdylib", "staticlib"]` in the GUI Rust lib's `Cargo.toml`. +- Configure the `pubspec.yaml` `flutter_rust_bridge` section with explicit `crate_dir: ../` (path from Flutter root to Rust crate). +- Verify with `otool -L` (macOS) or `dumpbin /dependents` (Windows) that the final bundle links the correct library. +- Add a smoke test to CI: build the release Flutter app, verify the native library is present in the bundle. + +**Warning signs:** +- `flutter run --debug` works (uses debug dylib in `target/debug/`) but `flutter run --release` fails. +- Error: "Failed to load dynamic library: libdiffusion_rs_gui.dylib: image not found." +- Linux: `error while loading shared libraries: libdiffusion_rs_gui.so`. + +**Phase that must address it:** Phase 2 (FFI wiring) — environment setup section. + +--- + +### Pitfall M-2: No Cancellation Path — Generation Cannot Be Stopped + +**What goes wrong:** stable-diffusion.cpp does not expose a cancellation API. Once generation starts, it runs to completion (or crash). The Flutter UI provides a "Stop" button but has no way to honour it. If the Dart isolate is killed while the Rust/C++ code is executing, the C++ context is not freed, causing a memory leak and potentially leaving GPU resources locked until process exit. + +**Why it happens:** Cancellation is rarely designed in at the start. The Rust API wraps the C++ library which has no abort signal. The common workaround (killing the Dart isolate) does not stop the native thread. + +**Consequences:** +- Users wait for the full generation even after clicking Stop. +- Repeated "stops" without actually stopping accumulate leaked C++ contexts. +- On VRAM-limited systems, leaked contexts prevent the next generation from starting. + +**Prevention:** +- In Phase 1 (mock), design the Stop button so it clearly communicates "will stop after current step" rather than "stops immediately" — set user expectations. +- In Phase 2, implement a Rust-side atomic bool abort flag. Pass it into the generation loop. Check it in the progress callback. This requires wrapping the C++ call or using a thread that can be polled. +- Alternative: use `process::exit()` as a last resort (nuclear option) — acceptable for desktop apps where the user explicitly requests it. +- Do not implement a "kill the isolate" cancellation — it does not stop native threads and leaks resources. + +**Warning signs:** +- Stop button is wired to `isolate.kill()` — this is the anti-pattern. +- Progress bar continues advancing after Stop is pressed. +- Second generation attempt fails with "model already loaded" or VRAM error. + +**Phase that must address it:** Phase 1 — Stop button design (communicates pending stop); Phase 2 — actual abort mechanism. + +--- + +### Pitfall M-3: token.txt Compile-Time Dependency Breaking Fresh Builds + +**What goes wrong:** `src/preset.rs` and `src/modifier.rs` use `include_str!("../token.txt")` evaluated at compile time. When the GUI Rust crate depends on the diffusion-rs library crate, `cargo build` for the GUI triggers a full library recompile — including the test files that contain `include_str!`. Even though those tests are `#[ignore]`d, the `include_str!` macro still runs at compile time. If `token.txt` does not exist, the build fails with a confusing "file not found" error that has nothing to do with the GUI. + +**Why it happens:** The `include_str!` is in test code, and Rust compiles test code even when tests are not run if the `#[cfg(test)]` attribute is present in a dependency. + +**Consequences:** +- CI/CD for the GUI fails on fresh checkout with: `error: couldn't read ../token.txt: No such file or directory`. +- New developer onboarding hits this immediately. +- If `token.txt` contains a real HuggingFace token and is committed to git (currently visible in root per CONCERNS.md), it is exposed in git history. + +**Prevention:** +- Create a placeholder empty `token.txt` in the repo root (no real token) with a clear comment. +- Add `token.txt` to `.gitignore` and document that users must create it locally with their real token only if needed for testing. +- In the GUI's `Cargo.toml`, depend on the diffusion-rs library with `default-features = false` and exclude test features. +- Guard the `include_str!` calls with `#[cfg(test)]` only in files that need it, so they are only compiled during `cargo test`, not `cargo build`. (This is a fix that should be contributed back to diffusion-rs.) + +**Warning signs:** +- Fresh checkout fails at the Rust compile step with `couldn't read ../token.txt`. +- The root directory contains a `token.txt` file tracked in git. + +**Phase that must address it:** Phase 2 setup — document the workaround clearly in the GUI's README; Phase 2 execution — create the placeholder file. + +--- + +### Pitfall M-4: Windows Path Handling — Non-UTF-8 Paths Silently Dropped + +**What goes wrong:** The diffusion-rs library uses `to_str().unwrap_or_default()` in `SafePathBuf` conversions (CONCERNS.md, `src/api.rs:1291`). On Windows, user profile paths can contain characters outside UTF-8 (e.g., certain CJK usernames). The `unwrap_or_default()` silently converts such paths to empty strings, causing the model file to not be found — with no error, just a silent failure or panic downstream. + +**Why it happens:** Rust's `Path::to_str()` returns `None` on non-UTF-8 paths (Windows-specific). The existing code swallows this `None`. + +**Consequences:** +- On Windows systems with non-ASCII usernames, model loading silently fails. +- The error manifests as "model not found" or a panic at the `CString::new(...).unwrap()` call that follows. +- No error reaches the Flutter UI — the app just hangs or crashes. + +**Prevention:** +- In the Flutter GUI, always use `path_provider`'s temp directory for output (already planned — this avoids user-profile paths for output). +- For model paths (which users specify), add a Dart-side validation that checks whether the path contains only ASCII before passing it to Rust. Show a clear error if not. +- Do not rely on the Rust library to handle this gracefully — it currently does not. + +**Warning signs:** +- Windows-only bug reports: "generation never starts." +- User's `%USERPROFILE%` path contains non-Latin characters. + +**Phase that must address it:** Phase 2 — add Dart-side path validation before any Rust call. + +--- + +### Pitfall M-5: Yaru on macOS/Windows — Font and Scroll Behavior Differences + +**What goes wrong:** Yaru ships the Ubuntu font and uses GTK-style spacing/sizing conventions. On macOS and Windows, Flutter's text rendering pipeline uses the platform's native font fallback chain when the bundled font is not explicitly loaded. If the Yaru setup does not properly load the Ubuntu font asset, text renders in the platform's default font (San Francisco on macOS, Segoe UI on Windows), which has different metrics. This causes layout overflow, clipped labels, and widgets that look correct on Linux but broken elsewhere. + +**Why it happens:** Yaru's Flutter package bundles the Ubuntu font, but it must be declared in the app's `pubspec.yaml` assets section to be available. If the developer installs Yaru and forgets to declare the font asset, the font silently falls back. + +**Consequences:** +- Text truncation in dropdowns and form labels on macOS/Windows. +- Pixel-level layout differences between platforms. +- Scroll physics differs: macOS uses momentum scrolling; Yaru's default scroll physics are Linux-tuned. + +**Prevention:** +- Follow Yaru's setup instructions exactly: add `uses-material-design: true` and the Yaru font assets to `pubspec.yaml`. +- Test the UI on all three target platforms in Phase 1, not just Linux. +- For scroll physics, use `ScrollConfiguration` with platform-adaptive physics explicitly. + +**Warning signs:** +- Text appears in a different font on macOS/Windows than on Linux. +- Form labels are clipped on macOS but fine on Linux. +- Dropdown widgets have different heights per platform. + +**Phase that must address it:** Phase 1 (mock UI) — catch this during initial cross-platform smoke testing. + +--- + +## Minor Pitfalls + +--- + +### Pitfall m-1: Temporary File Accumulation After Crash + +**What goes wrong:** Flutter's `path_provider` `getTemporaryDirectory()` returns a system temp directory, but the OS does NOT clean it on app exit. The planned cleanup (delete temp dir on app close) only runs if the app exits cleanly. If the app crashes (Rust panic, OOM, forced kill), the cleanup code never runs. Each crashed session leaves behind potentially large image files (512×512 to 1024×1024 PNG files from a batch generation can be 50–500MB total). + +**Why it happens:** Cleanup is typically implemented in `dispose()` or `AppLifecycleState.detached` handlers, neither of which fires on unclean exit. + +**Prevention:** +- On startup, scan the temp directory for any leftover files from previous sessions older than N hours and delete them. +- Name the session temp subdirectory with the process PID: `diffusion_rs_gui_/`. On startup, check for dirs whose PID no longer exists (using `Process.canRun` or platform-specific check) and delete them. +- Keep generated images small enough to not be catastrophic if leaked (use temp PNG, not uncompressed raw). + +**Warning signs:** +- User reports growing disk usage over time. +- Temp directory contains many `diffusion_rs_gui_*` folders. + +**Phase that must address it:** Phase 1 — design the session temp dir pattern; Phase 2 — implement the startup cleanup sweep. + +--- + +### Pitfall m-2: Lazy Model Loading Race — Second Generation Before First Finishes + +**What goes wrong:** diffusion-rs implements lazy model loading (recent commit `deb776a`) using unsafe pointer storage (`Option<(NonNull, ...)>`). The comment in CONCERNS.md notes "concurrent access patterns are untested." If the user somehow triggers a second generation (e.g., by clicking Start rapidly, or if the Stop button has a race), the second call may find the model mid-initialization with a partially initialized raw pointer. + +**Why it happens:** The lazy init is designed for single-threaded CLI use. In a GUI context with async callbacks and user input events firing concurrently, a TOCTOU (time-of-check-time-of-use) race becomes possible. + +**Prevention:** +- In the Flutter UI, disable the Start button immediately upon click and do not re-enable it until the result (success or error) arrives. Never re-enable it on Stop without waiting for the Rust thread to actually finish. +- In Rust, add a `Mutex` generation_in_progress guard at the FFI boundary that returns an error if a generation is already running. + +**Warning signs:** +- Start button can be clicked while generation is running (UI bug). +- Rust segfault with a backtrace touching `sd_ctx_t` initialization. + +**Phase that must address it:** Phase 2 — UI disable/enable logic is the first safeguard. + +--- + +### Pitfall m-3: macOS Code Signing — Native Library Not Signed + +**What goes wrong:** On macOS, if the Flutter desktop app is distributed outside the App Store (as a `.app` bundle), all bundled dylibs must be ad-hoc signed at minimum. The diffusion-rs `.dylib` compiled by `cargo build` is unsigned. When users download and run the app, Gatekeeper may block loading the library with "dylib cannot be opened because the developer cannot be verified." + +**Why it happens:** Cargo does not sign dylibs. The Flutter build process signs the `.app` bundle but may not recursively sign nested dylibs from Cargo unless explicitly configured. + +**Prevention:** +- In the release build script, run `codesign --force --sign - ` (ad-hoc) or with a Developer ID if distributing to other machines. +- Flutter's macOS build can be configured with a `Podfile`-level hook to sign all native libraries. +- Test on a second Mac that has never run the app in development mode (Gatekeeper is not suppressed there). + +**Warning signs:** +- App works on developer's Mac but crashes on another Mac on first launch. +- macOS Console shows `AMFI: is not signed` or `dyld: Library not loaded`. + +**Phase that must address it:** Phase 2 — add signing to the macOS release build. + +--- + +### Pitfall m-4: Git Submodule Not Initialized — Confusing Build Failures + +**What goes wrong:** `sys/stable-diffusion.cpp/` is a git submodule. A developer who clones the monorepo without `--recursive` and then tries to build the GUI Rust crate gets: `No such file or directory: sys/stable-diffusion.cpp/CMakeLists.txt`. This error appears in the `build.rs` CMake output, not as a clear message about the submodule. + +**Why it happens:** The submodule requirement is documented in the README but not enforced at the shell/CI level. The error message from CMake is not self-explanatory. + +**Prevention:** +- Add a `build.rs` check at the very start: verify `sys/stable-diffusion.cpp/CMakeLists.txt` exists and emit a clear `println!("cargo:warning=Run git submodule update --init --recursive")` if it does not, then `panic!`. +- Document the setup in the GUI's own README (not just the root README). + +**Warning signs:** +- Build fails with: `could not find CMakeLists.txt` or similar CMake error. +- The `sys/stable-diffusion.cpp/` directory is empty. + +**Phase that must address it:** Phase 2 setup — document in the GUI README. + +--- + +## Phase-Specific Warnings + +| Phase Topic | Likely Pitfall | Mitigation | +|-------------|---------------|------------| +| Phase 1 — Mock UI setup | Yaru font not bundled correctly on macOS/Windows | Test on non-Linux platform in Phase 1, not Phase 2 | +| Phase 1 — Stop button design | No cancellation API in C++ backend; UI must communicate "pending stop" not "immediate stop" | Design the UX honestly — "Stop after current step" | +| Phase 1 — Progress bar simulation | Using `Timer.periodic` vs `Stream` — wrong pattern learned in mock becomes wrong pattern in real wiring | Use `Stream`-based mock to mirror the real `StreamSink` API | +| Phase 2 — FFI bridge setup | Cargo workspace + Flutter subfolder: artifact path not found by flutter build | Configure `cargokit` paths explicitly; verify with release build smoke test | +| Phase 2 — First generation call | Sync Rust function blocks main isolate | Verify UI remains responsive by running a separate animation during generation | +| Phase 2 — Progress callbacks | C++ thread calling through FFI into Dart event loop | Use flutter_rust_bridge StreamSink; never store raw Dart port in C++ | +| Phase 2 — Panic safety | 40+ `.unwrap()` calls in diffusion-rs; any unusual input panics | Add `catch_unwind` wrappers; compile with `panic = "abort"` | +| Phase 2 — Windows testing | Non-UTF-8 user profile paths silently dropped | Add Dart-side ASCII path validation before passing to Rust | +| Phase 2 — macOS distribution | Unsigned dylib blocked by Gatekeeper | Ad-hoc sign in release build script | +| Phase 2 — Temp file cleanup | Crash leaves large image files in temp dir | Startup sweep to delete stale session directories | +| Phase 2 — token.txt build dep | Missing token.txt breaks GUI Rust build on fresh checkout | Create empty placeholder; document in GUI README | + +--- + +## Sources + +| Source | Provider | Confidence | +|--------|----------|------------| +| flutter_rust_bridge v2 documentation (architecture, isolate model, StreamSink, codegen) | Training knowledge (cutoff Aug 2025) | MEDIUM | +| diffusion-rs codebase analysis (CONCERNS.md: unsafe FFI, unwrap, token.txt, lazy loading) | Direct codebase read | HIGH | +| path_provider Flutter package behavior on desktop platforms | Training knowledge | MEDIUM | +| Yaru Flutter package cross-platform behavior | Training knowledge | MEDIUM | +| macOS Gatekeeper / dylib signing requirements | Training knowledge | MEDIUM | +| Rust panic-across-FFI undefined behavior (Rustonomicon) | Training knowledge | HIGH | +| Cargo workspace + cdylib linking patterns | Training knowledge | MEDIUM | diff --git a/.planning/research/STACK.md b/.planning/research/STACK.md new file mode 100644 index 0000000..7db27fa --- /dev/null +++ b/.planning/research/STACK.md @@ -0,0 +1,549 @@ +# Technology Stack — diffusion-rs GUI + +**Project:** diffusion-rs GUI (Flutter desktop wrapping Rust image-generation library) +**Researched:** 2026-06-18 +**Confidence:** MEDIUM (context7 unavailable; based on codebase inspection + training knowledge through August 2025; verify version pins before scaffolding) + +--- + +## Recommended Stack + +### Core Flutter / Dart + +| Technology | Version | Purpose | Why | +|------------|---------|---------|-----| +| Flutter SDK | >=3.22.0 (stable channel) | UI framework | Minimum for desktop stability + Impeller on macOS/Linux; 3.22 ships Dart 3.4 | +| Dart SDK | >=3.4.0 | Language | Required by flutter_rust_bridge 2.x; records, patterns, sealed classes all available | + +**Do NOT use Flutter beta/master channel.** Desktop rendering is production-stable on the stable channel since 3.x.

Il backend Rust (v0.1.20, ~35 preset, stable-diffusion.cpp sotto) è già feature-complete; il lavoro è interamente nel costruire il layer GUI. L'approccio raccomandato è un build a due fasi stretto: Phase 1 consegna una mock UI completamente funzionale — tutti i 15 campi input, barra di avanzamento, pannello preview, toggle tema — guidata da `MockGenerationService` senza alcuna dipendenza Rust. Phase 2 collega il backend Rust reale via flutter_rust_bridge 2.x sostituendo una singola riga nel provider. Questo disaccoppiamento è il cardine architetturale: permette allo sviluppo UI di procedere alla velocità di iterazione Flutter mentre le build del toolchain Rust/GPU vengono rimandate. + +Le decisioni tecnologiche chiave sono definite: Flutter 3.22+/Dart 3.4+ per la UI, flutter_rust_bridge 2.x (versione esatta pinnata uguale tra pub package e binary codegen) per FFI, Yaru 6.x per il design system, Riverpod 2.x per la gestione stato (4 provider: params, lifecycle generazione, progress, tema), e `path_provider` per la gestione cross-platform della temp directory. Il bridge crate `gui/rust/` deve vivere nel proprio workspace Cargo isolato — NON come membro del workspace root — per evitare trigger delle build CMake/GPU durante il codegen FRB. + +I rischi dominanti sono tutti concentrati in Phase 2: le chiamate Rust long-running devono essere `async` al confine FRB oppure la UI si blocca; i progress callback arrivano da thread C++ e devono fluire attraverso `StreamSink` per raggiungere il Dart event loop in sicurezza; e i 40+ `.unwrap()` in diffusion-rs rendono obbligatori i wrapper `catch_unwind` e `panic = "abort"` prima di qualsiasi test utente. Due blocchi immediati esistono indipendentemente dalla fase: i campi struct `Progress` in `src/api.rs` sono privati e necessitano `pub`, e un placeholder `token.txt` deve essere committato nella root del repo per sbloccare le fresh build CI. + +## Key Findings + +### Stack Raccomandato + +| Tecnologia | Versione | Ruolo | Rationale | +|------------|----------|-------|-----------| +| Flutter / Dart | 3.22+ / 3.4+ | UI framework | Minimo per stabilità desktop e pattern Dart richiesti da frb 2.x | +| flutter_rust_bridge | 2.7.0 (pub + cargo binary pinnati identicamente) | FFI bridge | Unica soluzione matura di FFI tipizzata Dart/Rust per desktop | +| Yaru + yaru_icons | ^6.1.0 / ^2.3.0 | Design system | Richiesto dallo spec; light/dark built-in; YaruPasswordField per token | +| Riverpod 2.x + @riverpod codegen | latest | State management | AsyncNotifier gestisce il lifecycle di generazione in modo idiomatico | +| window_manager | ^0.4.0 | Window control | Dimensione minima finestra, intercept close per cleanup temp | +| path_provider | ^2.1.4 | Temp dir | Path cross-platform corretti su macOS/Linux/Windows | +| multi_split_view | latest | Layout due pannelli | Drag handle resizable, min area constraints out of the box | + +**Regola critica:** il pacchetto `flutter_rust_bridge` su pub.dev e il binary `flutter_rust_bridge_codegen` su crates.io devono essere la stessa versione patch.

It delivers a complete two-panel GUI with all 15 CLI fields (minus batch), collapsible form sections, mock generation service emitting Stream-based progress, preview placeholder, and image saving -- all with zero Rust/GPU dependencies. + +The standard stack centers on Flutter 3.x with the `yaru` package (v10.2.0) for Ubuntu-style theming and widgets, `flutter_riverpod` (v3.3.2) for state management via AsyncNotifier, `multi_split_view` (v3.6.2) for the resizable two-panel layout, `file_picker` (v11.0.2) for save dialogs, and `path_provider` (v2.1.6) for temp directory management. The Yaru package includes all needed widgets: `YaruExpandable` for collapsible sections, `YaruExpansionPanel` as a coordinated accordion container, `YaruLinearProgressIndicator` and `YaruCircularProgressIndicator` for generation progress, and theme creation via `createYaruLightTheme()`/`createYaruDarkTheme()`. + +**Primary recommendation:** Use `YaruExpansionPanel` (not individual `YaruExpandable` widgets) for the four collapsible form sections, as it provides automatic dividers, coordinated collapse, and consistent styling. Use `CallbackShortcuts` (not `Shortcuts`+`Actions`) for Cmd/Ctrl+Enter since the shortcut does not need context-dependent behavior.

No batch field (removed from scope). +- **D-02:** Four sections: Model (preset dropdown + weights dropdown), Generation (prompt multiline, negative, steps, width, height, seed+dice-button), Post-processing (preview dropdown, upscaler dropdown, upscaler_scale field), Advanced (cache dropdown, token password field, low_vram toggle). +- **D-03:** Default state on app launch: Model + Generation expanded, Post-processing + Advanced collapsed. +- **D-04:** Field order within Generation: prompt, negative, steps, width/height, seed (dice button resets to -1). +- **D-05:** FORM-15 warning (upscaler active but cache = None): shown as inline text under the cache dropdown inside Advanced section. No auto-selection of cache; user must choose manually. +- **D-06:** Presets without Weight variants: weights dropdown is visible but disabled (label "N/A" or greyed-out). +- **D-07:** Feature-based folder structure under gui/lib/ (params/, generation/, output/, shared/). +- **D-08:** The Phase 1 to Phase 2 seam: GenerationService abstract class. MockGenerationService for Phase 1, RustGenerationService for Phase 2 via single provider line change. +- **D-09:** Left/right panel communication via shared Riverpod providers only. +- **D-10:** Dart hardcoded preset list replicates all presets from src/preset.rs. +- **D-11:** Weight dropdown labels use human-readable enum string (Q4_K, Q8_0, F16, F32, etc.). +- **D-12:** Initial right panel state: neutral placeholder with large icon + "Configure parameters and press Generate". +- **D-13:** During generation before first preview frame: centered YaruCircularProgressIndicator spinner. +- **D-14:** After image save: image remains visible + SnackBar briefly showing saved path.

wrong font + +### Pitfall 2: MultiSplitView Without Focus Scope +**What goes wrong:** Keyboard shortcuts stop working when user drags the split handle +**Why it happens:** MultiSplitView's divider captures focus, and the CallbackShortcuts binding loses its focus scope +**How to avoid:** Wrap the entire layout in a `Focus(autofocus: true, ...)` widget above the CallbackShortcuts; or place shortcuts at the Scaffold level +**Warning signs:** Cmd/Ctrl+Enter works initially but stops after interacting with the divider + +### Pitfall 3: Stream Not Cancelling on Widget Dispose +**What goes wrong:** Mock generation stream continues emitting after user navigates away or hot-reloads +**Why it happens:** Riverpod notifier subscribes to stream but does not cancel when provider is disposed +**How to avoid:** Use `ref.onDispose()` to cancel stream subscriptions in the generation notifier; or use `await for` which naturally handles generator cleanup +**Warning signs:** Multiple simultaneous generations running, state corruption + +### Pitfall 4: file_picker Platform Dependencies on Linux +**What goes wrong:** file_picker crashes or shows empty dialog on Linux +**Why it happens:** file_picker on Linux requires `zenity` or `kdialog` installed; missing on minimal Linux installs +**How to avoid:** Document the dependency; add a try/catch around saveFile() with a fallback error message +**Warning signs:** PlatformException on Linux only + +### Pitfall 5: Temp Directory Permissions on Windows +**What goes wrong:** App fails to create or delete temp directories on Windows +**Why it happens:** Windows temp directory paths are user-specific and may have long path limitations +**How to avoid:** Use path_provider (returns correct per-user temp path); keep filenames short; handle IOException +**Warning signs:** FileSystemException with "access denied" on Windows + +### Pitfall 6: DropdownButton State Not Updating +**What goes wrong:** Selecting a new preset does not update the weights dropdown +**Why it happens:** Weights dropdown value is stale because the provider holding weights list was not rebuilt when preset changed +**How to avoid:** Make weights dropdown a computed/derived value from the selected preset in the params provider; ensure the provider rebuilds when preset changes +**Warning signs:** Weights dropdown shows options from previous preset + +### Pitfall 7: Forgotten obscureText Toggle State +**What goes wrong:** Token field visibility toggle does not persist; toggling other sections resets it +**Why it happens:** obscureText state stored in local widget state that gets rebuilt when parent YaruExpansionPanel rerenders +**How to avoid:** Store the toggle state in the Riverpod params provider, not in local StatefulWidget state +**Warning signs:** Clicking another section header resets the token visibility + +## Code Examples + +### Flutter Project Creation Command +```bash +# Source: Flutter documentation [ASSUMED] +cd /path/to/diffusion-rs +flutter create gui --platforms=macos,linux,windows --project-name=diffusion_rs_gui +``` + +### App Entry Point (main.dart) +```dart +// Source: training knowledge [ASSUMED] +import 'package:flutter/material.dart';

Phase 1 consegna una GUI Flutter ## Phase Details ### Phase 1: Flutter UI Foundation (Mock Mode) + **Goal**: L'utente può interagire con una GUI desktop a due pannelli completa — tutti i 15 campi CLI, barra di avanzamento, preview placeholder e salvataggio immagine — senza che nessuna dipendenza Rust/GPU sia presente sulla macchina. **Mode**: mvp **Depends on**: Nothing (first phase) **Requirements**: SETUP-01, SETUP-02, SETUP-03, SETUP-04, UI-01, UI-02, UI-03, UI-04, UI-05, FORM-01, FORM-02, FORM-03, FORM-04, FORM-05, FORM-06, FORM-07, FORM-08, FORM-09, FORM-10, FORM-11, FORM-12, FORM-13, FORM-14, FORM-15, GEN-01, GEN-02, GEN-03, GEN-04, GEN-05, GEN-06, OUT-01, OUT-02, OUT-03, OUT-04, OUT-05, OUT-06, TMP-01, TMP-02, TMP-03, MOCK-01, MOCK-02, MOCK-03, MOCK-04 **Success Criteria** (what must be TRUE): + 1. L'utente può aprire l'app su macOS, Linux e Windows, vedere il layout a due pannelli ridimensionabile con tema Yaru (chiaro/scuro/sistema), e il toggle tema funziona senza riavviare l'app 2. L'utente può compilare tutti i 15 campi del form (inclusi dropdown contestuale pesi, campo password token con toggle visibilità, seed con bottone dado, e warning upscaler/cache) e premere Genera — tutti i campi si disabilitano, la barra di avanzamento avanza con contatore "Step N / totale", e si riabilita al termine 3. Al termine della generazione mock (~5 secondi), il pannello destro mostra un'immagine placeholder; l'utente può premere Salva, scegliere una cartella e trovare il file PNG salvato con nome `{preset}_{seed}_{timestamp}.png` 4. I file temporanei di sessioni precedenti (crash) vengono rimossi all'avvio; i file della sessione corrente vengono rimossi alla chiusura normale dell'app 5. La scorciatoia Cmd/Ctrl+Enter avvia la generazione esattamente come il bottone Genera -**Plans:** 3 plans + +**Plans:** 1/3 plans executed Plans: -- [ ] 01-01-PLAN.md -- Walking skeleton: Flutter project scaffold, two-panel Yaru layout, mock generation service, progress bar, placeholder image + +- [x] 01-01-PLAN.md -- Walking skeleton: Flutter project scaffold, two-panel Yaru layout, mock generation service, progress bar, placeholder image - [ ] 01-02-PLAN.md -- Complete form: all 15 CLI fields in 4 collapsible sections, preset catalog, field validation, keyboard shortcut - [ ] 01-03-PLAN.md -- Output panel: save flow with file_picker, temp directory lifecycle management **UI hint**: yes ### Phase 2: Rust Bridge Wiring + **Goal**: L'utente può avviare una vera generazione di immagini con diffusion-rs direttamente dalla GUI, con preview live aggiornata ad ogni step e immagine finale reale — nessun mock. **Mode**: mvp **Depends on**: Phase 1 **Requirements**: FRB-01, FRB-02, FRB-03, FRB-04, FRB-05, FRB-06, FRB-07, FRB-08, FRB-09 **Success Criteria** (what must be TRUE): + 1. Il dropdown preset nella GUI è popolato dinamicamente da `get_presets()` Rust (non da lista hardcoded Dart); il dropdown pesi si aggiorna contestualmente via `get_weights_for_preset()` 2. Premendo Genera con parametri validi, il pannello destro mostra preview live aggiornate ad ogni step di diffusione, e al termine compare l'immagine finale generata da diffusion-rs 3. Un panic Rust durante la generazione non causa crash della GUI: l'errore è intercettato da `catch_unwind`, la UI si riabilita e mostra un messaggio di errore leggibile 4. La CI verifica automaticamente che i file generati da FRB codegen siano sincronizzati con il codebase Rust (diff check fallisce la build se desincronizzati) + **Plans**: TBD ## Progress | Phase | Plans Complete | Status | Completed | |-------|----------------|--------|-----------| -| 1.

The phase delivers: +- `gui/rust/` Cargo crate exposing `get_presets()`, `get_weights_for_preset()`, `generate_image_stream()` via FRB +- `RustGenerationService` in Dart consuming the FRB bindings +- Live preview images per step (file-based, PREVIEW_PROJ) +- Real final image from diffusion-rs in the right panel +- Graceful error handling (Rust panics caught via `catch_unwind`, errors shown as modal dialog) + +No new UI fields or layout changes. The seam architecture from Phase 1 (D-08) makes this a purely internal swap. + + + + +## Implementation Decisions + +### Preview Frames per Step (intermediate images) + +- **D-01:** Phase 2 shows **both** a progress bar AND real intermediate denoising images in the right panel per step. Not mock placeholders — actual frames from the diffusion process. +- **D-02:** Preview delivery is **file-based**: `ConfigBuilder` sets `preview_output = {tmpdir}/preview.png` and `preview_mode = PreviewType::PREVIEW_PROJ` (Fast, per CLI `PreviewMode::Fast` → `PREVIEW_PROJ`). The existing `save_preview_local` C callback writes the PNG to disk each step. +- **D-03:** `RustGenerationService` reads the preview file bytes from disk **after each progress event** and includes them as `previewImage: Uint8List?` in `ProgressEvent`. Read-after-write race condition is accepted — if the file isn't ready yet, `previewImage` is null and the UI shows the previous frame (graceful degradation, no crash). +- **D-04:** The right panel shows "Downloading model..." (spinner + static text) until the first `ProgressEvent` with `step == 1` arrives. This covers the case where diffusion-rs downloads the model before starting inference. No download progress tracking (v2 MDL-01). + +### Error Handling UX + +- **D-05:** On **Rust error** (DiffusionError returned or panic caught by FRB-06 `catch_unwind`): show an **AlertDialog modale** with the error message. The form re-enables after dismissal. No SnackBar for errors — modal ensures the user sees it. +- **D-06:** The error message displayed in the dialog is the Rust error string as-is (e.g., "Forward: out of memory" from DiffusionError). No localization or prettification in Phase 2. +- **D-07:** `catch_unwind` (FRB-06) is on ALL FFI entry points in `gui/rust/`.

The existing Phase 1 `GenerationService` seam makes the swap a single-line provider change in `generation_provider.dart`. The core challenge is correctly mapping diffusion-rs's builder-based, blocking, `mpsc::Sender`-driven API to FRB 2.x's `StreamSink` streaming pattern. + +flutter_rust_bridge 2.x (stable 2.12.0) provides first-class `StreamSink` support: a Rust function taking `StreamSink` as a parameter automatically generates a Dart function returning `Stream`. The Rust function runs on a background thread (FRB spawns it); the sink can emit multiple values over its lifetime. Error handling uses `sink.add_error(anyhow::Error)` to surface exceptions on the Dart side. FRB automatically catches Rust panics and converts them to Dart exceptions, satisfying the `catch_unwind` requirement (FRB-06) without manual wrapping for most cases -- though explicit `catch_unwind` in the wrapper adds defense-in-depth against C++ abort signals. + +The build integration uses Cargokit (default FRB backend), which hooks into Flutter's native build system (CMakeLists.txt on Linux/Windows, Xcode on macOS) to automatically compile the Rust crate during `flutter build`/`flutter run`. FRB codegen (`flutter_rust_bridge_codegen generate`) must be run after Rust API changes to regenerate Dart bindings; per D-08, this is integrated into the build workflow. + +**Primary recommendation:** Use `StreamSink` for `generate_image_stream()`, spawn the blocking `gen_img_with_progress()` call on a dedicated `std::thread`, relay `mpsc::Receiver` messages plus file-based preview bytes through the sink, and wrap the entire call in `catch_unwind` for defense-in-depth. + + +## User Constraints (from CONTEXT.md) + +### Locked Decisions +- **D-01:** Phase 2 shows both a progress bar AND real intermediate denoising images per step +- **D-02:** Preview delivery is file-based: `ConfigBuilder` sets `preview_output = {tmpdir}/preview.png` and `preview_mode = PreviewType::PREVIEW_PROJ` +- **D-03:** `RustGenerationService` reads preview file bytes from disk after each progress event; race condition accepted (null previewImage shows previous frame) +- **D-04:** Right panel shows "Downloading model..."

All complex logic stays in diffusion-rs core. + +## Common Pitfalls + +### Pitfall 1: Preview File Race Condition +**What goes wrong:** Dart reads preview.png while the C callback is still writing it, resulting in a corrupted/truncated image +**Why it happens:** `save_preview_local` writes the PNG file from the C inference thread; the progress callback fires nearly simultaneously +**How to avoid:** Per D-03, accept the race condition. If `File.readAsBytes()` fails or returns empty data, set `previewImage = null` in the event. The UI shows the previous frame (graceful degradation). Wrap the file read in try/catch. +**Warning signs:** Occasional garbled preview frames during fast-stepping presets (1-4 steps) + +### Pitfall 2: FRB Codegen Stale Bindings +**What goes wrong:** Changing Rust function signatures without running `flutter_rust_bridge_codegen generate` causes Dart compilation errors +**Why it happens:** FRB codegen outputs Dart files that mirror Rust function signatures; they must be regenerated after Rust API changes +**How to avoid:** D-08 says codegen is build-integrated. In practice, run `flutter_rust_bridge_codegen generate` after any change to `gui/rust/src/api.rs`. Consider adding a pre-build script or documenting the workflow clearly. +**Warning signs:** Dart errors about missing methods or wrong parameter types in generated files + +### Pitfall 3: `panic = "abort"` vs `catch_unwind` +**What goes wrong:** With `panic = "abort"` in release profile (D-13), `catch_unwind` has no effect -- the process terminates immediately on panic +**Why it happens:** `panic = "abort"` skips unwinding; `catch_unwind` requires unwinding to work +**How to avoid:** This is intentional per D-13. In debug/dev builds (where `panic = "unwind"` is default), `catch_unwind` works and helps during development. In release, panics abort -- but they should never occur in production if errors are properly handled via `Result`. +**Warning signs:** App crashes with no error dialog in release mode -- indicates a Rust panic that should have been a `Result::Err` + +### Pitfall 4: ModelConfig Mutability and Thread Safety +**What goes wrong:** `gen_img_with_progress` requires `&mut ModelConfig`, and FRB may try to call functions from different threads +**Why it happens:** `ModelConfig` caches the sd_ctx internally (lazy initialization), requiring mutable access +**How to avoid:** Create `ModelConfig` inside the spawned `std::thread`, use it once, and drop it. Do NOT share `ModelConfig` across calls. Each generation creates a fresh context. +**Warning signs:** Borrow checker errors, or mysterious crashes from concurrent context access + +### Pitfall 5: macOS Sandbox and File Access +**What goes wrong:** Writing preview/output PNGs to a path outside the sandbox container fails silently +**Why it happens:** macOS app sandbox restricts file system access; `com.apple.security.app-sandbox = true` is set in entitlements +**How to avoid:** Use `TempDirectoryManager.sessionPath` for all file paths. `path_provider`'s `getTemporaryDirectory()` returns the sandbox-safe container temp dir. Never use absolute paths outside the container. +**Warning signs:** File not found errors when reading preview.png, despite the Rust generation succeeding + +### Pitfall 6: Cargokit First Build Time +**What goes wrong:** First `flutter run` after adding `gui/rust/` takes 10-30+ minutes due to full C++/CMake build of stable-diffusion.cpp +**Why it happens:** `diffusion-rs` path dependency triggers `diffusion-rs-sys` build.rs, which compiles stable-diffusion.cpp from the submodule via CMake +**How to avoid:** Document this in the README. Subsequent builds are incremental and fast. Consider using `--release` only when needed. +**Warning signs:** Developer thinks the build is stuck -- it's actually compiling GGML/stable-diffusion.cpp + +### Pitfall 7: Weight Enum Mismatch +**What goes wrong:** Passing an invalid weight string for a preset causes `try_into().unwrap()` to panic in the Rust `get_preset()`-like mapping +**Why it happens:** `WeightType::from_str()` succeeds but `TryInto` fails for a weight variant not in that preset's subenum +**How to avoid:** Validate weight string against the preset's subenum VARIANTS before constructing the `Preset` enum. Return `Result::Err` instead of unwrapping. +**Warning signs:** Panic on generation start with certain preset/weight combinations + +## Code Examples + +### Complete generate_image_stream Implementation Pattern +```rust +// Source: diffusion-rs codebase (src/api.rs, cli/src/main.rs) + FRB docs +use std::sync::mpsc; +use std::path::PathBuf; +use std::fs; +use crate::frb_generated::StreamSink; +use anyhow::Result; +use diffusion_rs::api::{gen_img_with_progress, PreviewType}; +use diffusion_rs::preset::PresetBuilder; +use diffusion_rs::util::set_hf_token; + +pub fn generate_image_stream( + params: GuiParams, + sink: StreamSink, +) -> Result<()> { + std::thread::spawn(move || { + let result = std::panic::catch_unwind(std::panic::AssertUnwindSafe(|| { + // 1.

Add dependencies: `flutter_rust_bridge = "2.12.0"`, `anyhow = "1.0"`, `strum = { version = "0.27", features = ["derive"] }`. Set `[lib]` crate-type to `["cdylib", "staticlib"]`.

Use `#[flutter_rust_bridge::frb(init)]` on a pub fn `init_app()` that calls `flutter_rust_bridge::setup_default_user_utils()`. + + 3. Create gui/rust/src/gui_params.rs with the GuiParams DTO struct (per D-11 / FRB-04). All fields must be FRB-compatible primitives only. Fields: preset (String), weight (Option of String), prompt (String), negative_prompt (Option of String), steps (Option of i32), width (Option of i32), height (Option of i32), batch_count (i32), seed (i64), cache_mode (Option of String), preview_mode (String), upscaler (Option of String), upscaler_scale (f32), token (Option of String), low_vram (bool), preview_output (String), output (String).

Create gui/rust/src/bridge.rs with the mapping logic from GuiParams to diffusion-rs builders. This module contains: + + a) A `map_preset(preset_str, weight_str)` function that takes the preset name as a string and an optional weight name string, and returns `Result of Preset, anyhow::Error`. Match on the preset string (use `PresetDiscriminants::from_str` from strum), then for each discriminant that requires a weight, parse the weight string via `WeightType::from_str` followed by `try_into()` for the specific subenum type. Use the subenum default if weight_str is None. Return a descriptive anyhow error on invalid preset or weight string instead of panicking (per Research Pitfall 7). + + b) A `build_configs(params: GuiParams)` function that constructs `(Config, ModelConfig)` from GuiParams. Use the same pattern as cli/src/main.rs: create a PresetBuilder, set preset and prompt, then use `with_modifier` to apply optional overrides for steps, width, height, negative_prompt, seed, batch_count, output path, preview_output, preview_mode (set to PreviewType::PREVIEW_PROJ per D-02), preview_interval (1). Map cache_mode string to the appropriate builder call (UCACHE/EASYCACHE/DBCACHE/TAYLORSEER/CACHEDIT/SPECTRUM using default params builders, same pattern as cli/src/main.rs lines 194-210). Map upscaler string to the appropriate Upscaler enum variant and call model_config.hires_params() with HiresParamsBuilder using upscaler_scale. If low_vram is true, set vae_tiling(true) and flash_attention(true). If token is provided and non-empty, call set_hf_token before building. + + 2. Create gui/rust/src/api.rs with three FRB-annotated public functions: + + a) `get_presets()` — annotated `#[flutter_rust_bridge::frb(sync)]`. Use `PresetDiscriminants::VARIANTS.iter().map(|s| s.to_string()).collect()` to return Vec of String. + + b) `get_weights_for_preset(preset: String)` — annotated `#[flutter_rust_bridge::frb(sync)]`. Parse the preset string to PresetDiscriminants via from_str, then match to return the appropriate subenum VARIANTS (e.g. for Flux1Dev return Flux1Weight::VARIANTS, for Chroma return ChromaWeight::VARIANTS, etc.). For presets without weights (StableDiffusion1_4, StableDiffusion1_5, etc.) return an empty Vec. Map each variant name to String. + + c) `generate_image_stream(params: GuiParams, sink: StreamSink of GuiProgressEvent)` — the streaming generation function. Define `GuiProgressEvent` struct in this file with fields: step (i32), steps (i32), time (f32), preview_image (Option of Vec of u8), final_image (Option of Vec of u8). The function body: + - Spawns a std::thread (per Research threading pattern). + - Inside the thread, wraps ALL work in `std::panic::catch_unwind(std::panic::AssertUnwindSafe(...))` (per D-07 / FRB-06). + - Inside catch_unwind: call bridge::build_configs(params) to get (config, model_config). Create an mpsc channel. Spawn a SECOND thread (relay thread) that loops on rx.recv(), reads preview file bytes from preview_output path via fs::read (wrapped in ok() per D-03 — race accepted), and calls sink.add(GuiProgressEvent) with the progress data and preview bytes. The main thread calls gen_img_with_progress(config, model_config, tx). After gen_img completes and tx drops, the relay thread exits. Then read the final image bytes from output path, and emit one final GuiProgressEvent with final_image populated. + - On catch_unwind Ok(Ok(())): stream completes naturally. + - On catch_unwind Ok(Err(e)): call sink.add_error with anyhow error wrapping the DiffusionError. + - On catch_unwind Err(panic): extract panic message (downcast to String or str, fallback to "Unknown panic"), call sink.add_error. + - Return Ok(()) from the outer function. + + The StreamSink import path is `crate::frb_generated::StreamSink`. Note: `frb_generated` module does not exist until codegen runs. Use `#[allow(unused_imports)]` on this import and include a module-level comment explaining that this file requires FRB codegen to compile fully. For cargo check to pass before codegen, gate the StreamSink-dependent code behind a `cfg` or accept that the full compile happens only after codegen. ALTERNATIVELY: create a minimal gui/rust/src/frb_generated.rs stub that re-exports a placeholder StreamSink type for compilation, which will be overwritten by codegen. The executor should choose whichever approach makes cargo check pass cleanly. + + + cd /Users/flavio.bizzarri/repo/diffusion-rs/gui/rust && cargo check 2>&1 | tail -10 + + gui/rust/src/api.rs exports three public functions: get_presets returns all preset names as Vec of String (FRB-01), get_weights_for_preset returns weight variants per preset (FRB-02), generate_image_stream takes GuiParams and StreamSink and bridges to gen_img_with_progress with two-thread relay and catch_unwind (FRB-03, FRB-06). gui/rust/src/bridge.rs maps GuiParams to diffusion-rs builders with proper error handling. cargo check passes. + + + + + +## Trust Boundaries + +| Boundary | Description | +|----------|-------------| +| Dart GUI to Rust FFI | User-supplied form parameters cross from untrusted Dart input into Rust FFI functions via GuiParams | +| Rust FFI to C++ backend | GuiParams-derived configs pass to unsafe C FFI calls in diffusion-rs-sys | +| File system (preview/output) | Preview and output PNG files written by C callback, read by Rust relay thread | + +## STRIDE Threat Register + +| Threat ID | Category | Component | Disposition | Mitigation Plan | +|-----------|----------|-----------|-------------|-----------------| +| T-02-01 | Tampering | GuiParams preset/weight strings | mitigate | Validate via from_str parse in bridge.rs; reject invalid strings with descriptive error | +| T-02-02 | Denial of Service | Rust panic across FFI boundary | mitigate | catch_unwind on all FFI entry points (D-07/FRB-06); panic=abort in release (D-13) | +| T-02-03 | Information Disclosure | HF token in memory | accept | Token stored in OnceLock, not logged; same pattern as core crate | +| T-02-04 | Tampering | preview_output / output paths | mitigate | Paths provided by TempDirectoryManager in Dart; Rust does not validate but trusts caller | +| T-02-05 | Denial of Service | Preview file read race | accept | Per D-03: race accepted; fs::read failure returns None, UI shows previous frame | +| T-02-SC | Tampering | cargo dependencies | mitigate | All packages verified in RESEARCH.md Package Legitimacy Audit; flutter_rust_bridge and anyhow approved | + + + +cargo check passes in gui/rust/ directory. +grep confirms Progress fields are pub in src/api.rs. +gui/rust/Cargo.toml contains panic = "abort" in release profile. +gui/rust/Cargo.toml contains diffusion-rs path dependency. +get_presets function exists and references PresetDiscriminants::VARIANTS. +get_weights_for_preset function exists with match arms for all weight-bearing presets. +generate_image_stream function exists with catch_unwind, std::thread::spawn, mpsc channel, and StreamSink usage. + + + +gui/rust/ compiles as a valid Cargo crate with all three FRB functions implemented.

Run `flutter_rust_bridge_codegen integrate` inside the gui/ directory to set up Cargokit build hooks (per D-08). This command configures CMakeLists.txt (Linux/Windows) and Xcode (macOS) to compile gui/rust/ during flutter build. If the codegen CLI is not installed, install it first: `cargo install flutter_rust_bridge_codegen --version 2.12.0`. After integration, run `flutter_rust_bridge_codegen generate` to produce the Dart binding files from the Rust API. + + 2. Add `flutter_rust_bridge: ^2.12.0` to the dependencies section of gui/pubspec.yaml (if not already added by the integrate command). Run `flutter pub get` in gui/ to resolve dependencies. + + 3. Create gui/lib/features/generation/services/rust_generation_service.dart implementing the GenerationService abstract class. The class: + - Has a constructor that takes a Ref parameter (for accessing providers). + - Implements `Stream of ProgressEvent generate(Map of String dynamic params)` as an async* method. + - Inside generate(): + a) Read tempDirectoryManagerProvider from ref to get the session temp path. + b) Construct the preview path as `{sessionPath}/preview.png` and output path as `{sessionPath}/output_{millisecondsSinceEpoch}.png`. + c) Convert the params Map to the FRB-generated GuiParams type. Map keys match the ParamsState.toMap() output: preset, weight, prompt, negativePrompt, steps, width, height, seed, cacheMode, previewMode, upscalerMode (mapped to upscaler), upscalerScale, token, lowVram. Add previewOutput and output paths. Set batchCount to 1 (batch_count field). Map "None" string values for cacheMode, upscaler, previewMode to null Option values on the Rust side (pass null/empty string and let the Rust bridge handle the mapping). + d) Call the FRB-generated `generateImageStream(params: guiParams)` function which returns a Dart Stream of GuiProgressEvent. + e) await-for over the stream. For each GuiProgressEvent, yield a ProgressEvent with step, steps, time, and previewImage (convert Vec of u8 to Uint8List if present). When the event has finalImage populated, yield a final ProgressEvent where step equals steps (isComplete == true) with the final image bytes as previewImage. + + Note: The exact import path for FRB-generated bindings depends on the output of flutter_rust_bridge_codegen generate. Inspect the generated files after codegen and use the correct import path (typically something like `package:diffusion_rs_gui/src/rust/api/...`). + + + cd /Users/flavio.bizzarri/repo/diffusion-rs/gui && flutter analyze 2>&1 | tail -10 + + FRB codegen integration is complete. flutter_rust_bridge dependency is in pubspec.yaml. RustGenerationService exists and implements GenerationService. The FRB-generated Dart bindings are present and importable. flutter analyze passes. + + + + Task 2: Provider swap, error dialog, output panel updates for downloading state and live preview + gui/lib/features/generation/providers/generation_provider.dart, gui/lib/shared/widgets/error_dialog.dart, gui/lib/features/output/output_panel.dart, gui/macos/Runner/DebugProfile.entitlements + + 1. Create gui/lib/shared/widgets/error_dialog.dart with a utility function `showErrorDialog(BuildContext context, String errorMessage)` that shows a modal AlertDialog per D-05. Title: "Generation Failed". Body: the raw Rust error string passed as errorMessage (per D-06, no localization). Single action button: TextButton with text "OK" that pops the dialog via Navigator.of(context).pop(). Use showDialog with barrierDismissible: false so the user must acknowledge via OK. + + 2. Modify gui/lib/features/generation/providers/generation_provider.dart: + a) Swap the generationServiceProvider from MockGenerationService to RustGenerationService (per FRB-09). Change line 130 from `return MockGenerationService()` to `return RustGenerationService(ref)`. Update imports accordingly: add the rust_generation_service import, keep mock_generation_service import (do not delete the file, keep for development/testing). + b) Update the GenerationNotifier.generate() method to handle real images from the Rust backend. The current implementation copies a placeholder asset on completion. Instead, when event.isComplete is true AND event.previewImage is not null, write event.previewImage bytes to the output file in the session temp directory, then set imagePath to that file. If event.previewImage is null on completion (edge case), fall back to checking if the output file already exists on disk (the Rust backend writes it directly). + c) During generation (not complete), when event.previewImage is not null, write the preview bytes to a file in the session temp directory and add an `imagePath` field to the generating state so the output panel can display the live preview. Extend GenerationState to include an optional previewImageBytes field (Uint8List?) or write preview bytes to a known preview file path and pass that path. Choose whichever approach is simpler: adding a `previewBytes` Uint8List? field to GenerationState avoids file I/O on the Dart side and lets the output panel display directly from memory. + + 3. Modify gui/lib/features/output/output_panel.dart: + a) Update the generating state renderer. When currentStep is 0 (no progress yet), show "Downloading model..." text below the YaruCircularProgressIndicator spinner (per D-04). This covers the model download phase before inference starts. + b) When generating with progress (currentStep > 0), if the GenerationState has previewBytes (or a preview image path), display the live preview image above the progress bar using Image.memory(previewBytes) with BoxFit.contain (per D-01, D-02, D-03). If previewBytes is null for a given step, show just the progress bar (previous frame behavior). + c) When status is error, trigger the error dialog. Call showErrorDialog from error_dialog.dart with the error message. After the dialog is dismissed, the form re-enables (per D-05). The error state rendering in the panel can remain as-is (icon + message) as a fallback, but the modal dialog should fire via a post-frame callback or a listener on the generation provider. + + 4. Update gui/macos/Runner/DebugProfile.entitlements to add `com.apple.security.network.client` (true) if not already present. The app needs outbound network access to download models from HuggingFace during generation. (The existing entitlements have network.server but not network.client.) + + + cd /Users/flavio.bizzarri/repo/diffusion-rs/gui && flutter analyze 2>&1 | tail -10 + + generationServiceProvider returns RustGenerationService (FRB-09). Error dialog widget exists with "Generation Failed" title and OK button (D-05, D-06).

RustGenerationService - Run flutter_rust_bridge_codegen integrate to set up Cargokit build hooks - Add flutter_rust_bridge 2.12.0 and rust_lib_diffusion_rs_gui to pubspec.yaml - Create Dart API bindings (GuiParams, GuiProgressEvent types and function wrappers) - Update frb_generated files with correct API signatures for our Rust crate - Create RustGenerationService implementing GenerationService via FRB bindings - Add RustLib.init() call to main.dart for FRB runtime initialization - Add Cargokit rust_builder plugin for native Rust compilation during flutter build ---

Richiede 3-5 righe di modifica in `model_section.dart` e `params_provider.dart`. + +2. **FRB codegen mai eseguito — binding Dart sono stub manuali** — `frb_generated.io.dart:RustLibWire` non ha wire methods; il binding non puo' effettuare FFI call. Richiede che il developer esegua `flutter_rust_bridge_codegen generate` dopo una build C++ completa. Questa e' una precondizione obbligatoria per qualsiasi test runtime. + +3. **catch_unwind mancante su get_presets() e get_weights_for_preset()** — FRB-06 e' parzialmente implementato. Se queste funzioni sync panickano (es. per un preset mal formato o un problema di inizializzazione), la GUI crasha senza recovery. Fix semplice: avvolgere il corpo delle due funzioni in `std::panic::catch_unwind`. + +4. **flutter analyze (root) fallisce con 68 issues in Cargokit** — non blocca `flutter analyze lib/` (0 issues) ma indica che il build_tool Cargokit bundled ha dipendenze rotte. Potrebbe impattare il primo `flutter build`. + +**Root cause comune per gap 1 e 2:** Il SUMMARY documenta che il codegen reale non e' stato eseguito e che i binding Dart sono "stub type-correct". La conseguenza e' che nemmeno il wiring UI->FFI->Rust e' stato verificato in pratica, e il Step successivo obbligatorio (chiamare getPresets() dalla UI) non e' avvenuto. + +--- + +_Verificato: 2026-06-21_ +_Verifier: Claude (gsd-verifier)_ From 3f0bb95f17a32f8b93f91c19c3071284fa717a98 Mon Sep 17 00:00:00 2001 From: newfla Date: Sun, 21 Jun 2026 20:22:35 +0200 Subject: [PATCH 37/62] =?UTF-8?q?fix(02):=20close=20all=204=20verification?= =?UTF-8?q?=20gaps=20=E2=80=94=20FRB=20codegen,=20catch=5Funwind,=20preset?= =?UTF-8?q?=20UI=20wiring?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Gap 1 (SC-1): model_section.dart and params_provider.dart now call getPresets() and getWeightsForPreset() from FRB bindings instead of PresetCatalog hardcoded lists. Deleted obsolete api/api.dart stub that conflicted with real codegen output. Gap 2: Replaced stub FRB bindings with output from actual flutter_rust_bridge_codegen generate run (api.dart, gui_params.dart, frb_generated.dart/.io.dart/.web.dart, frb_generated.rs). Gap 3 (FRB-06): get_presets() and get_weights_for_preset() now wrapped in catch_unwind; private _get_weights_for_preset() helper avoids AssertUnwindSafe capture of non-UnwindSafe closure.

La conseguenza e' che nemmeno il wiring UI->FFI->Rust e' stato verificato in pratica, e il Step successivo obbligatorio (chiamare getPresets() dalla UI) non e' avvenuto. +4. **flutter analyze Cargokit** — OVERRIDE. 68 issues in codice terze parti vendored (`rust_builder/cargokit/`). `flutter analyze lib/` passa con 0 errori. Non e' codice progetto. --- From 16f255e45c7657fc73060467405a7b9d294c5b02 Mon Sep 17 00:00:00 2001 From: newfla Date: Tue, 23 Jun 2026 16:14:46 +0200 Subject: [PATCH 39/62] =?UTF-8?q?fix(gui):=20fix=20macOS=20build=20?= =?UTF-8?q?=E2=80=94=20package=20name=20and=20missing=20frameworks?= MIME-Version: 1.0 Content-Type: text/plain;

Cargokit build integration, RustGenerationService with live preview streaming, provider swap (Phase 2 Plan 02, 13 min) + +### What Worked + +- **Mock-first sequencing**: Building Phase 1 with a full mock before touching Rust was the right call. It let the form, layout, and save flow be tested end-to-end with zero build chain friction. Phase 2 was then purely about wiring, not UI iteration. +- **GenerationService abstract seam**: The abstract `GenerationService` with `Stream generate()` made Phase 2 trivially correct — swapping Mock to Rust was literally one line in the provider (FRB-09). +- **Exhaustive match arms**: Using exhaustive (no catch-all) match on PresetDiscriminants in the Rust bridge gives compile-time safety when new presets are added to diffusion-rs. Zero runtime surprises. +- **GSD workflow discipline**: The pre-planning research phase for Phase 2 surfaced the cargokit + FRB integration pattern clearly before any code was written. + +### What Was Inefficient + +- **FRB codegen in worktree**: The flutter_rust_bridge_codegen generate step requires `cargo expand` which triggers the full C++ build of stable-diffusion.cpp. This cannot run in a worktree/CI context without a full environment. Manual binding stubs were created and then regenerated after the build succeeded locally. Detected during Phase 2 UAT when the app showed a black screen (stem mismatch). +- **Cargokit package name discovery**: The root cause of the build failure (Cargo package name `diffusion-rs-gui` vs pod target `rust_lib_diffusion_rs_gui`) required reading deep into cargokit's `build_pod.dart` and `artifacts_provider.dart` source to understand. This is a gotcha that should be documented upfront for any flutter_rust_bridge project on macOS. +- **Missing linker flags**: `-lc++ -framework Accelerate` were not included in the initial podspec. Discovered only after the build succeeded but linking failed with undefined C++ stdlib and BLAS symbols. Should be part of any cargokit podspec that wraps a Rust crate depending on stable-diffusion.cpp. + +### Patterns Established + +- **Cargokit naming rule**: Cargo package name must equal the CocoaPods pod target name exactly (underscores, no hyphens). The pod target is `rust_lib_XXX`; the Cargo `[package] name` must be `rust_lib_XXX`. +- **FRB stem regeneration**: After any Cargo package rename, always re-run `flutter_rust_bridge_codegen generate` to update the `stem` in `frb_generated.dart`. Stem mismatch causes a black screen (library not found) with no obvious error message. +- **podspec linker flags for stable-diffusion.cpp**: `OTHER_LDFLAGS[sdk=macosx*]` must include `-lc++ -framework Accelerate`. Without them, hundreds of undefined symbol errors from C++ stdlib and Apple Accelerate. +- **Two-thread StreamSink relay**: The generate_image_stream pattern — worker thread calls `gen_img_with_progress`, relay thread bridges `mpsc::Receiver` to `StreamSink` — is the correct FRB 2.x streaming idiom. `executeNormal` (not `executeStream`) handles the sink port serialization. +- **previewBytes in-memory display**: Pass `previewBytes: Uint8List?` in state instead of writing preview to file and reading back. Cleaner and faster for per-step preview updates. +- **DropdownButton + InputDecorator pattern**: Flutter 3.44.x deprecated `DropdownButtonFormField.value`; use `DropdownButton` inside `InputDecorator` + `DropdownButtonHideUnderline` for equivalent styling with controlled Riverpod state. + +### Key Lessons + +1. **Name your Cargo crate after the pod target from the start.** The pod target name comes from `flutter_rust_bridge_codegen integrate` and is `rust_lib_{yourname}`. Set `[package] name = "rust_lib_{yourname}"` in Cargo.toml immediately. Renaming later requires regenerating FRB bindings. +2. **Document linker flags in the podspec template.** Every project using stable-diffusion.cpp on macOS will need `-lc++ -framework Accelerate`. Add to `rust_builder/macos/*.podspec` as part of the cargokit scaffold. +3. **FRB codegen needs a live build environment.** The CI diff-check (FRB-08) is the right pattern, but the first generation of bindings must happen locally with a full build chain. Plan for this as a developer setup step. +4. **catch_unwind is defense-in-depth, not the only safety.** The FRB runtime itself is resilient to errors returned as Err variants. catch_unwind guards against panics; the real reliability comes from returning proper Results from generate_image_stream. + +--- + +## Cross-Milestone Trends + +| Metric | v1.0 | +|--------|------| +| Phases | 2 | +| Plans | 5 | +| Commits | 44 | +| LOC (project) | ~4,782 | +| Timeline | 6 days | +| Requirements validated | 45/46 | +| UAT pass rate | 15/16 (1 skipped) | +| Build failures before green | 3 (package name, linker, FRB stem) | diff --git a/.planning/ROADMAP.md b/.planning/ROADMAP.md index 3755907..d004dbc 100644 --- a/.planning/ROADMAP.md +++ b/.planning/ROADMAP.md @@ -1,70 +1,29 @@ # Roadmap: diffusion-rs GUI **Project:** diffusion-rs GUI -**Core Value:** L'utente può configurare e avviare una generazione di immagini con lo stesso set di opzioni della CLI, senza aprire un terminale. -**Total Phases:** 2 -**Requirements:** 46 v1 requirements +**Core Value:** L'utente può configurare e avviare una vera generazione di immagini con lo stesso set di opzioni della CLI, senza aprire un terminale, con preview live aggiornata ad ogni step. --- -## Overview +## Milestones -Il progetto si articola in due fasi verticali.
