When implementing nodes that perform I/O operations (file reading, network requests) or expensive computations, you should check for cancellation at appropriate boundaries. + +## Cancellation Architecture + +### How It Works + +1. **CancellationToken**: A thread-safe token shared between the main thread and render worker +2. **Cooperative checks**: Nodes check `is_cancelled()` at iteration boundaries +3. **Early return**: When cancelled, evaluation stops and returns cached partial results +4. **RAII cleanup**: Resources are automatically cleaned up via Rust's Drop trait + +### Cancellation Check Locations + +The evaluation engine automatically checks for cancellation at: +- **Before each node**: Before starting to evaluate any node +- **During list-matching iterations**: Between iterations in list-matching loops + +For standard nodes, this provides < 500ms response time for typical workloads. + +## Implementing Async-Aware Nodes + +### Basic Pattern + +For nodes that perform expensive operations: + +```rust +fn execute_expensive_node( + node: &Node, + inputs: &HashMap, + cancel_token: &CancellationToken, +) -> EvalResult { + // Check cancellation before starting + if cancel_token.is_cancelled() { + return Err(EvalError::Cancelled); + } + + // Do work in chunks, checking periodically + let mut results = Vec::new(); + for item in items { + // Check at iteration boundaries + if cancel_token.is_cancelled() { + return Err(EvalError::Cancelled); + } + + let result = process_item(item); + results.push(result); + } + + Ok(NodeOutput::from(results)) +} +``` + +### I/O Operations with smol + +For nodes that perform async I/O (file reading, network requests), use the `smol` runtime: + +```rust +use smol::fs; +use smol::future::block_on; + +fn execute_file_read_node( + node: &Node, + inputs: &HashMap, + cancel_token: &CancellationToken, +) -> EvalResult { + let path = get_string(inputs, "path", ""); + + // Use smol for async file operations + let content = block_on(async { + // Check cancellation before I/O + if cancel_token.is_cancelled() { + return Err(std::io::Error::new( + std::io::ErrorKind::Interrupted, + "Cancelled", + )); + } + + fs::read_to_string(&path).await + }); + + match content { + Ok(text) => Ok(NodeOutput::String(text)), + Err(e) if e.kind() == std::io::ErrorKind::Interrupted => { + Err(EvalError::Cancelled) + } + Err(e) => Err(EvalError::ProcessingError(format!( + "{}: {}", + node.name, e + ))), + } +} +``` + +### Network Requests + +```rust +use smol::net::TcpStream; +use smol::io::AsyncReadExt; + +async fn fetch_url(url: &str, cancel_token: &CancellationToken) -> Result { + // Periodically check cancellation during long operations + if cancel_token.is_cancelled() { + return Err(EvalError::Cancelled); + } + + // Use async-net or smol's networking + let stream = TcpStream::connect(url).await + .map_err(|e| EvalError::ProcessingError(e.to_string()))?; + + // Read with cancellation checks + let mut buffer = Vec::new(); + // ... read in chunks, checking cancel_token between reads + + Ok(String::from_utf8_lossy(&buffer).to_string()) +} +``` + +## Best Practices + +### Check Frequency + +- **Too few checks**: User waits too long for cancellation (> 500ms) +- **Too many checks**: Performance overhead from atomic reads +- **Rule of thumb**: Check every ~100ms of work, or at natural iteration boundaries + +### Resource Cleanup + +Use Rust's RAII pattern for automatic cleanup: + +```rust +struct TempFile { + path: PathBuf, +} + +impl Drop for TempFile { + fn drop(&mut self) { + // Automatically cleaned up even on cancellation + let _ = std::fs::remove_file(&self.path); + } +} +``` + +### Cache Preservation + +When implementing caching, ensure partial results are preserved: + +```rust +// Good: Cache results as you go +for (i, item) in items.iter().enumerate() { + if cancel_token.is_cancelled() { + // partial_cache already contains results [0..i) + return Err(EvalError::Cancelled); + } + + let result = process(item); + partial_cache.insert(i, result.clone()); + results.push(result); +} + +// Bad: Only cache at the end +let results: Vec<_> = items.iter().map(process).collect(); +cache.insert_all(results); // Lost if cancelled +``` + +## Testing Async Nodes + +### Basic Cancellation Test + +```rust +#[test] +fn test_node_respects_cancellation() { + let token = CancellationToken::new(); + let mut cache = HashMap::new(); + + // Pre-cancel + token.cancel(); + + let result = evaluate_network_cancellable(&library, &token, &mut cache); + + assert!(matches!(result, EvalOutcome::Cancelled)); +} +``` + +### Response Time Test + +```rust +#[test] +fn

List Broadcasting (Most Impactful Difference) + +The Java evaluator has a "broadcasting" mechanism: when a node's single-value port is connected to an upstream node that produces multiple values (a list), the Java evaluator calls the node function once per value in the list, collecting results into a list. + +**Java (NodeContext.java):** Uses `NodeArgumentIterator` which creates argument maps for each index up to `biggestArgumentList`. For list-range ports, the entire list is passed. For value-range ports, individual elements are passed via `wrappingGet`. + +**Rust (eval.rs):** `compute_iteration_count`, `build_iteration_inputs`, `collect_results` implement the same mechanism. + +**Examples affected:** Most examples that use grid → translate, number lists → shapes, etc. + +### 2. Geometry vs Paths Semantics (Fundamental Type System Limitation) + +**Java:** `Geometry` is a first-class type that holds multiple `Path` objects as a single compound value. When used in list broadcasting, `Geometry` has `list_len=1`. A `List` has `list_len=N`. + +**Rust:** We added `NodeOutput::Geometry(Vec)` with `list_len=1`. However, when `collect_results` collects N Geometry items (from N broadcasting iterations), it flattens them into `Paths(total_paths)` with `list_len=total_paths`. This changes downstream broadcasting behavior. + +**Example:** reflect with keep_original=true returns Geometry(2) per iteration. N iterations → collect_results → Paths(2N) with list_len=2N, instead of Java's N items with list_len=N. + +**Fix attempted and reverted:** Merging all contours into a single Path preserves list_len=1 per iteration but loses path rendering identity (halves path count for rendering). + +**Proper fix:** Would require a `NodeOutput::Geometries(Vec>)` variant to represent "list of Geometry" with correct list_len semantics. + +**Examples affected:** Invader, Name Generator + +### 3. SVG Rendering Strategy + +**Java SVGRenderer:** +- Uses centered `viewBox`: `viewBox="-w/2 -h/2 w h"` +- Path-level rendering: each Path becomes a `` element +- Smart number formatting: integers without decimals, floats with 2 decimal places +- Minimal attributes: omits fill when black (SVG default), omits stroke when not set + +**Rust SVG renderer (after fixes):** +- Same centered `viewBox` +- Same smart number formatting +- Same fill/stroke attribute strategy + +### 4. Boolean Path Operations (Compound Node) + +**Java:** Uses `java.awt.geom.Area` for boolean operations. Area natively handles compound shapes. + +**Rust:** Uses `i_overlay` crate with f32 SingleFloatOverlay. Bezier curves are flattened to 16-segment line approximations before boolean ops. When compound receives a Geometry input, all paths are merged into a single compound path (concatenating contours) before the boolean operation, matching Java's Area behavior. + +### 5. Text-on-Path Algorithm + +**Java:** Python `pyvector.text_on_path()` function places text characters along a path using font metrics, parametric t values, and rotation. + +**Rust:** Implemented in `font.rs` as `text_on_path()`. Per-character algorithm: +1. Calculate parametric position `t` along the path +2. Get point and tangent angle at `t` +3. Render character glyph using `TtfOutlineBuilder` +4. Apply transform: `rotate(angle - 180°).then(translate(point))` + +Supports "leading" and "trailing" alignment with margin and baseline_offset parameters. + +### 6. Fill/Stroke Defaults + +**Java Path:** Default fill = `Color.BLACK`, default stroke = `null` +**Rust Path (after fix):** Same defaults + +### 7. LIST-range Port Resolution + +When nodes are loaded from `.ndbx` files, they typically only have port overrides. The `PortRange` (VALUE vs LIST) comes from prototype definitions. + +**Solution:** Added `is_list_range_port()` lookup table mapping `(prototype, port_name)` → `bool`. + +### 8. Type Conversion + +Java's `TypeConversions.java` automatically converts upstream outputs to match port types. Most critical: `Geometry → Points` (extract contour points). + +**Rust:** `convert_input_types()` + `convert_output_for_port()` + `get_prototype_port_type()`. + +### 9. Font Rendering Differences + +Java uses system fonts (AWT) while Rust uses a bundled Inter font via ttf-parser. This causes path count differences in text-heavy examples because different fonts have different glyph decompositions. + +**Affected examples:** TextFX (-5 paths), Sine Text (+23), Animated Logo (+218), Spider Text (+430) + +## Resolution Strategies (Final State) + +### Completed (19 fixes) +1. SVG format alignment (centered viewBox, smartFloat, fill/stroke, path format, attribute order) +2. List broadcasting (compute_iteration_count, build_iteration_inputs, collect_results) +3. LIST-range port resolution (is_list_range_port lookup table) +4. Generic list.combine (handles all NodeOutput types) +5. Type conversion (Path→Points, Float→Point, Int→Float) +6. Default values alignment (fill, stroke, polygon, star, grid, arc, etc.) +7. copy node fix (removed incorrect LIST-range on shape port) +8. corevector.point (separated from make_point, Point pass-through) +9. corevector.sort (handle Points input) +10. data.lookup (Point x/y property support) +11. corevector.null (pass through any input type) +12. corevector.delete (handle lists of paths + point-in-path containment) +13. Point-in-path test (Path::contains() with ray-casting + bezier flattening) +14. Prototype port type lookup (get_prototype_port_type() for type conversion) +15.

Previously skipped, causing Strings(["x"]) to not match get_string() which expects String("x"). + +### SVG Format Fixes +1. **Centered viewBox** — `viewBox="-500 -500 1000 1000"` without translate group +2. **smartFloat formatting** — Integers without decimals, floats with 2 decimals +3. **Fill/stroke conventions** — Match Java: omit black fill, omit null stroke +4. **Attribute ordering** — Match Java HashMap iteration: d, stroke-width, fill, stroke +5. **Path command format** — No spaces between commands +6. **Trailing newline** — Removed trailing newline after `` + +### Node Implementation Fixes +1. **polygon** — Fixed start angle (0° for align=false), removed extra closing point +2. **star** — Fixed diameter→radius conversion, swapped sin/cos to match Java +3. **Path defaults** — Changed default fill from WHITE to BLACK, default stroke to None +4. **sort_points** — Added point sorting in filters.rs + +## Progress Across Sessions + +| Iteration | Match Count | Rate | +|-----------|-------------|------| +| Initial (SVGs generated) | 9/46 | 19.6% | +| After SVG format fixes | 14/46 | 30.4% | +| After list broadcasting | 23/46 | 50.0% | +| After copy/point/delete fixes | 29/46 | 63.0% | +| After subnetwork eval | 32/46 | 69.6% | +| After file I/O (import_csv/svg) | 37/46 | 80.4% | +| After text_on_path | 38/46 | 82.6% | +| After compound (i_overlay) | 39/46 | 84.8% | +| After Geometry variant + fixes | 40/46 | 87.0% | +| After build_iteration_inputs fix | 42/46 | 91.3% | + +## Remaining Work + +### P1: Medium Impact (Would fix 1 example) +1. **Geometry-as-List in combine** — Java's Geometry extends AbstractList, so when a Geometry is combined via list.combine, Java expands it into individual paths rather than treating it as a single compound item. Fixing this would resolve the Invader example. + +### P2: Low Impact (Would partially improve 3 examples) +1. **System font support** — Use matching system fonts instead of bundled Inter to reduce text path count differences. This would improve TextFX, Sine Text, and Animated Logo, though exact matches are unlikely without identical font engine implementations. diff --git a/scripts/build-linux-appimage.sh b/scripts/build-linux-appimage.sh index ff4e8c524..c91f1c230 100755 --- a/scripts/build-linux-appimage.sh +++ b/scripts/build-linux-appimage.sh @@ -37,10 +37,10 @@ fi # Build the binary cd "$PROJECT_ROOT" -cargo build $CARGO_FLAGS -p nodebox-gui +cargo build $CARGO_FLAGS -p nodebox # Set up paths -BINARY_PATH="$PROJECT_ROOT/target/$BUILD_TYPE/nodebox-gui" +BINARY_PATH="$PROJECT_ROOT/target/$BUILD_TYPE/NodeBox" APPDIR="$PROJECT_ROOT/target/$BUILD_TYPE/NodeBox.AppDir" APPIMAGE_PATH="$PROJECT_ROOT/target/$BUILD_TYPE/NodeBox-$VERSION-$ARCH.AppImage" diff --git a/scripts/build-mac-bundle.sh b/scripts/build-mac-bundle.sh index 3ca072d07..d04ad4784 100755 --- a/scripts/build-mac-bundle.sh +++ b/scripts/build-mac-bundle.sh @@ -21,7 +21,7 @@ echo "Building NodeBox $VERSION ($BUILD_TYPE)..." # Build the binary cd "$PROJECT_ROOT" -cargo build $CARGO_FLAGS +cargo build $CARGO_FLAGS -p nodebox # Set up paths BINARY_PATH="$PROJECT_ROOT/target/$BUILD_TYPE/NodeBox" diff --git a/scripts/build-windows-installer.ps1 b/scripts/build-windows-installer.ps1 index d0d06e36a..5e5996605 100644 --- a/scripts/build-windows-installer.ps1 +++ b/scripts/build-windows-installer.ps1 @@ -30,9 +30,9 @@ $CargoFlags = if ($Debug) { @() } else { @("--release") } # Build the binary Set-Location $ProjectRoot -cargo build @CargoFlags -p nodebox-gui +cargo build @CargoFlags -p nodebox -$BinaryPath = "$ProjectRoot\target\$BuildType\nodebox-gui.exe" +$BinaryPath = "$ProjectRoot\target\$BuildType\NodeBox.exe" $OutputDir = "$ProjectRoot\target\$BuildType\installer" # Create output directory @@ -58,6 +58,6 @@ Write-Host "" Write-Host "To create an MSI installer:" Write-Host " 1.
