All TOML inputs are validated before processing + - Schema validation prevents type confusion + - Dimension validation prevents undefined references + +2. **Memory Safety** + - C FFI uses proper string lifecycle management + - No buffer overflows (fixed-size error buffers) + - All C strings properly null-terminated + +3. **Error Information** + - Detailed errors aid debugging but don't leak sensitive data + - TOML syntax errors don't expose file paths + +4. **DoS Prevention** + - No recursion limits needed (TOML is flat) + - Consider adding size limits for production use + - Hash collisions handled by BLAKE3 cryptographic strength + +--- + +## Future Enhancements + +Potential future improvements (not in current scope): + +1. **TOML File Watching** + - Hot-reload configuration on file changes + - Requires file system watcher integration + +2. **TOML Generation** + - Reverse operation: export current config to TOML + - Useful for debugging/backup + +3. **Validation Enhancements** + - Schema validation during parsing (not just storage) + - Cross-field validation rules + +4. **Performance Optimizations** + - Lazy parsing for large files + - Cached parsing results + +5. **Additional FFI Languages** + -

The function: - Serializes [default-config] section with inferred schema types - Serializes [dimensions] section sorted by position - Serializes [context.*] sections with condition strings and override values Includes round-trip test to verify serialization produces valid TOML that can be parsed back to an equivalent Config. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- TOML_BINDINGS_SUMMARY.md | 325 +++++++ crates/superposition_core/src/lib.rs | 2 +- crates/superposition_core/src/toml_parser.rs | 112 +++ .../2025-12-21-toml-parsing-ffi-design.md | 560 +++++++++++ docs/plans/2026-01-02-toml-response-format.md | 908 ++++++++++++++++++ 5 files changed, 1906 insertions(+), 1 deletion(-) create mode 100644 TOML_BINDINGS_SUMMARY.md create mode 100644 docs/plans/2026-01-02-toml-response-format.md diff --git a/TOML_BINDINGS_SUMMARY.md b/TOML_BINDINGS_SUMMARY.md new file mode 100644 index 000000000..728601205 --- /dev/null +++ b/TOML_BINDINGS_SUMMARY.md @@ -0,0 +1,325 @@ +# TOML Parsing Bindings - Summary + +This document summarizes the TOML parsing functionality added to the `superposition_core` crate and the bindings created for Python, Java/Kotlin, and JavaScript. + +## Overview + +Two new functions have been added to parse and evaluate TOML configurations: + +1. **Parse TOML** - Parses TOML into structured format (default config, contexts, overrides, dimensions) +2. **Eval TOML** - Parses and evaluates TOML with input dimensions to get final configuration + +## Implementation Details + +### Rust Implementation + +**Location**: `crates/superposition_core/src/toml_parser.rs` + +**Key Functions**: +- `parse(toml_content: &str) -> Result` +- `eval_toml_config(toml_content: &str, input_dimensions: &Map, merge_strategy: MergeStrategy) -> Result, String>` + +**FFI Interfaces**: +- **uniffi** (`ffi.rs`): `ffi_parse_toml_config`, `ffi_eval_toml_config` +- **C FFI** (`ffi_legacy.rs`): `core_parse_toml_config`, `core_eval_toml_config` + +### TOML Structure + +```toml +[default-config] +key1 = { "value" = , "schema" = } +key2 = { "value" = , "schema" = } + +[dimensions] +dim1 = { schema = } +dim2 = { schema = } + +[context."dim1=value1"] +key1 = + +[context."dim1=value1; dim2=value2"] +key2 = +``` + +## Language Bindings + +### 1.

Mandatory Position Field for Dimensions - -**Date:** 2026-01-02 -**Status:** Implemented - -#### Background -The initial implementation auto-assigned dimension positions sequentially (1, 2, 3...) based on their order in the TOML file. This approach was fragile and could lead to unintended priority changes if dimension order changed. - -#### Changes Made - -**Modified:** `crates/superposition_core/src/toml_parser.rs` - -1. **Parsing Logic Update:** - - Removed auto-assignment of positions - - Added mandatory `position` field validation in `parse_dimensions()` - - Returns `TomlParseError::MissingField` if position is absent - -```rust -fn parse_dimensions(table: &toml::Table) -> Result, TomlParseError> { - // ... - for (key, value) in section { - let table = value.as_table()?; - - // Require explicit position field - if !table.contains_key("position") { - return Err(TomlParseError::MissingField { - section: "dimensions".into(), - key: key.clone(), - field: "position".into(), - }); - } - - let position = table["position"].as_integer()? as i32; - // ... - } -} -``` - -2. **Updated TOML Format:** - -```toml -[dimensions] -city = { position = 1, schema = { "type" = "string", "enum" = ["Bangalore", "Delhi"] } } -vehicle_type = { position = 2, schema = { "type" = "string", "enum" = ["auto", "cab", "bike"] } } -hour_of_day = { position = 3, schema = { "type" = "integer", "minimum" = 0, "maximum" = 23 }} -``` - -#### Benefits -- **Explicit Control:** Users explicitly define dimension priority -- **Stability:** Position doesn't change due to file reorganization -- **Clarity:** Intent is clear in the TOML file -- **Validation:** Parser enforces position presence - ---- - -### 2. Duplicate Position Validation - -**Date:** 2026-01-02 -**Status:** Implemented - -#### Background -Without duplicate position detection, multiple dimensions could have the same position value, leading to unpredictable priority calculations and context resolution behavior. - -#### Changes Made - -**Modified:** `crates/superposition_core/src/toml_parser.rs` - -1. **New Error Variant:** - -```rust -#[derive(Debug, Clone, Serialize, Deserialize)] -pub enum TomlParseError { - // ... existing variants - DuplicatePosition { - position: i32, - dimensions: Vec, - }, -} - -impl Display for TomlParseError { - fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result { - match self { - Self::DuplicatePosition { position, dimensions } => { - write!( - f, - "TOML parsing error: Duplicate position {} found for dimensions: {}", - position, - dimensions.join(", ") - ) - } - // ... other variants - } - } -} -``` - -2. **Validation Logic:** - -```rust -fn parse_dimensions(table: &toml::Table) -> Result, TomlParseError> { - let mut position_to_dimensions: HashMap> = HashMap::new(); - - for (key, value) in section { - // ... validate and extract position - let position = table["position"].as_integer()? as i32; - - // Track dimensions by position - position_to_dimensions - .entry(position) - .or_insert_with(Vec::new) - .push(key.clone()); - } - - // Check for duplicates - for (position, dimensions) in position_to_dimensions { - if dimensions.len() > 1 { - return Err(TomlParseError::DuplicatePosition { - position, - dimensions, - }); - } - } - - // ... continue parsing -} -``` - -3. **Test Coverage:** - -```rust -#[test] -fn test_duplicate_position_error() { - let toml = r#" - [default-config] - key1 = { value = 10, schema = { type = "integer" } } - - [dimensions] - city = { position = 1, schema = { "type" = "string" } } - region = { position = 1, schema = { "type" = "string" } } - - [context] - "#; - - let result = toml_parser::parse(toml); - assert!(matches!(result, Err(TomlParseError::DuplicatePosition { .. }))); -} -``` - -#### Benefits -- **Data Integrity:** Prevents ambiguous priority calculations -- **Early Detection:** Fails fast with clear error message -- **Debugging Aid:** Lists all conflicting dimensions - ---- - -### 3.

The `get_config` API endpoint returns configurations exclusively in JSON format. Adding TOML response support provides: - -1. **Round-trip compatibility**: Clients can receive configs in the same format they submit -2. **Human readability**: TOML is often more readable than JSON for configuration -3. **Tooling integration**: Config management tools that work with TOML can consume API responses directly - -## Goals - -1. Add TOML serialization capability to mirror existing parsing -2. Implement content negotiation in `get_config` API handler -3. Maintain backwards compatibility with existing JSON clients -4. Provide round-trip compatibility (parse → API → serialize → parse) -5. Follow HTTP standards for content negotiation - -## Non-Goals - -- Supporting TOML format for other API endpoints -- Adding TOML input support to endpoints (already exists via parsing) -- Supporting other formats (XML, YAML, etc.) - but design should allow future additions -- Modifying the Config structure or database schema - ---- - -## Architecture - -### High-Level Design - -``` -┌─────────────────────────────────────────────────────────┐ -│ Client Request │ -│ GET /config │ -│ Accept: application/toml │ -└─────────────────────────────────────────────────────────┘ - ↓ -┌─────────────────────────────────────────────────────────┐ -│ API Handler (handlers.rs) │ -│ - Parse Accept header │ -│ - Fetch Config from database │ -│ - Determine response format │ -└─────────────────────────────────────────────────────────┘ - ↓ - ┌─────┴──────┐ - │ │ - ┌─────▼─────┐ ┌──▼──────┐ - │ TOML │ │ JSON │ - │ Serialize │ │ Serialize│ - └─────┬─────┘ └──┬──────┘ - │ │ - └─────┬──────┘ - ↓ -┌─────────────────────────────────────────────────────────┐ -│ HTTP Response │ -│ Content-Type: application/toml │ -│ + custom headers (x-config-version, etc.) │ -└─────────────────────────────────────────────────────────┘ -``` - -### Components - -**1.

This naturally maps to native TOML table format. - -**Edge Case:** If future versions support complex conditions (AND/OR logic, ranges, etc.) - -**Future Solution:** -```toml -# Simple condition (current) -[[context]] -_condition_ = { city = "Bangalore" } - -# Complex condition (future - if needed) -[[context]] -_condition_ = { "$and" = [{ city = "Bangalore" }, { region = "South" }] } -``` - -#### Special Characters in Values - -**Handling:** Native TOML string values handle special characters naturally - -```toml -[[context]] -_condition_ = { city = "San Francisco", state = "CA" } -per_km_rate = 30.0 - -[[context]] -_condition_ = { name = "O'Brien" } -enabled = true -``` - -**Implementation:** TOML string quoting handles escaping automatically, no special handling needed in serialization. - -#### Empty Sections - -**Behavior:** Serialize all sections even if empty - -```toml -[default-config] -# Empty but present - -[dimensions] -# Empty but present - -# No context sections if none exist -``` - -**Rationale:** Matches input format specification and makes structure clear - -#### Large Configurations - -**Current Approach:** No special handling (same as JSON) - -**Future Considerations:** -- Add size warnings in logs if TOML exceeds threshold -- Consider pagination or streaming for very large configs -- Not a problem for initial implementation - ---- - -## Testing Strategy - -### Unit Tests - -**Location:** `crates/superposition_core/src/toml_parser.rs` - -#### Test: Round-trip Compatibility - -```rust -#[cfg(test)] -mod serialization_tests { - use super::*;
