Lentil Hoffman Date: Sun, 22 Jun 2025 20:42:05 -0500 Subject: [PATCH 11/28] feat: enable inter-plugin state sharing in CustomResolver - Update ResolverPlugin interface to include context in update and resolve methods - Modify CustomResolver to pass entity state and resolved values to plugins - Update built-in plugins to accept and use the new context parameter - Add comprehensive test for inter-plugin communication - Add documentation for the new view composition patterns This change enables plugins to access each other's states during both update and resolve phases, allowing for more powerful and flexible resolver compositions. --- __tests__/unit/core/json-ast.test.ts | 4 +- .../views/resolvers/custom-resolvers.test.ts | 89 +++++++ .../resolvers/relationship-graph.test.ts | 67

Collect all plugin states before processing updates +2. Pass the complete state to each plugin during updates and resolution +3. Maintain backward compatibility with existing plugins + +### Example: Discounted Price Plugin + +Here's a practical example of a plugin that calculates a discounted price based on another property: + +```typescript +class DiscountedPricePlugin implements ResolverPlugin<{ price: number }> { + name = 'discounted-price'; + + initialize() { + return { price: 0 }; + } + + update( + state: { price: number }, + newValue: PropertyTypes, + _delta: CollapsedDelta, + _allStates?: Record + ) { + if (typeof newValue === 'number') { + return { price: newValue }; + } + return state; + } + + resolve( + state: { price: number }, + allStates?: Record + ): number | undefined { + // Access the discount value from another plugin's state + const discountState = allStates?.['discount'] as { value: number } | undefined; + if (discountState) { + // Apply discount if available + return state.price * (1 - (discountState.value / 100)); + } + return state.price; + } +} + +// Usage with a discount plugin +const resolver = new CustomResolver(losslessView, { + price: new DiscountedPricePlugin(), + discount: new LastWriteWinsPlugin() +}); +``` + +### Best Practices + +1. **Dependency Management**: + - Clearly document which properties your plugin depends on + - Handle cases where dependencies might be undefined + - Consider using TypeScript type guards for safer property access + +2. **Performance Considerations**: + - Access only the states you need in the `allStates` object + - Consider caching resolved values if the same calculation is performed multiple times + +3. **Testing**: + - Test plugins with and without their dependencies + - Verify behavior when dependencies are updated in different orders + - Test edge cases like missing or invalid dependencies + +### Built-in Plugins + +All built-in plugins have been updated to be compatible with the new interface: + +- `LastWriteWinsPlugin` +- `FirstWriteWinsPlugin` +- `ConcatenationPlugin` +- `MajorityVotePlugin` +- `MinPlugin` +- `MaxPlugin` + +These plugins maintain backward compatibility while supporting the new functionality. + +## Implementation Status + +The inter-plugin dependency feature has been implemented and includes: + +1.

Modify CustomResolver Implementation + +#### 2.1 Update Reducer Method +Modify the `reducer` method to filter states before passing to plugins: + +```typescript +public reducer( + acc: CustomResolverAccumulator, + cur: LosslessViewOne +): CustomResolverAccumulator { + // ... existing setup code ... + + // Process each property in execution order + for (const propertyId of executionOrder) { + // ... existing delta processing ... + + // Create filtered states object with only declared dependencies + const visibleStates: Record = {}; + + // Add states for declared dependencies + if (plugin.dependencies) { + for (const dep of plugin.dependencies) { + if (allStates[dep] !== undefined) { + visibleStates[dep] = allStates[dep]; + } + } + } + + // Pass only visible states to the plugin + propertyState.state = propertyState.plugin.update( + propertyState.state, + value, + delta, + visibleStates + ); + + // ... rest of the method ... + } +} +``` + +#### 2.2 Update Resolver Method +Similarly update the `resolver` method: + +```typescript +resolver(cur: CustomResolverAccumulator): CustomResolverResult { + const res: CustomResolverResult = {}; + + for (const [entityId, entity] of Object.entries(cur)) { + const entityResult = { id: entityId, properties: {} }; + const allStates: Record = {}; + + // First pass: collect all states + for (const [propId, propState] of Object.entries(entity.properties)) { + allStates[propId] = propState.state; + } + + // Second pass: resolve each property with filtered states + for (const [propId, propState] of Object.entries(entity.properties)) { + const plugin = propState.plugin; + const visibleStates: Record = {}; + + // Only include declared dependencies + if (plugin.dependencies) { + for (const dep of plugin.dependencies) { + if (allStates[dep] !== undefined) { + visibleStates[dep] = allStates[dep]; + } + } + } + + const resolvedValue = plugin.resolve(propState.state, visibleStates); + if (resolvedValue !== undefined) { + entityResult.properties[propId] = resolvedValue; + } + } + + if (Object.keys(entityResult.properties).length > 0) { + res[entityId] = entityResult; + } + } + + return res; +} +``` + +### 3. Add Validation +Add validation to ensure dependencies exist: + +```typescript +private validateDependencies(): void { + // Existing cycle detection... + + // Add validation that all dependencies exist + for (const [pluginId, plugin] of Object.entries(this.config)) { + for (const dep of plugin.dependencies || []) { + if (!this.config[dep]) { + throw new Error(`Plugin '${pluginId}' depends on unknown property: ${dep}`); + } + } + } +} +``` + +### 4. Update Tests +1. Add tests for state visibility: + - Test that plugins only receive their declared dependencies + - Test that plugins can't access undeclared dependencies + - Test that dependency validation works + - Test that existing functionality remains unchanged + +2. Update existing tests to account for the new behavior + +## Migration Strategy +1. This is a breaking change for any plugins that were accessing undeclared dependencies +2. Add warnings in the next minor version +3. Make the behavior opt-in initially with a flag +4. In the next major version, make it the default + +## Implementation Steps +1. [ ] Add the state filtering to `reducer` +2. [ ] Add the state filtering to `resolver` +3. [ ] Update dependency validation +4. [ ] Add comprehensive tests +5. [ ] Update documentation +6. [ ] Add deprecation warnings for plugins accessing undeclared dependencies + +## Future Considerations +1. Add a debug mode that logs when plugins access undeclared dependencies +2. Consider adding granular permissions (read/write) for dependencies +3. Add support for wildcard dependencies for plugins that need access to many properties \ No newline at end of file diff --git a/plans/view-composition.md b/plans/view-composition.md deleted file mode 100644 index 3a0f402..0000000 --- a/plans/view-composition.md +++ /dev/null @@ -1,182 +0,0 @@ -# View Composition with Combined State - -## Overview - -This document outlines the design for composing multiple lossy views using a combined state approach. This pattern allows different resolvers to work on their own parts of the state while sharing the same underlying delta stream. - -## Core Concept - -The combined state approach involves: -1. Creating a parent resolver that manages multiple child resolvers -2. Each child resolver maintains its own state -3. The parent coordinates the initialization, reduction, and resolution of child states -4. The final result combines the outputs of all child resolvers - -## Implementation Pattern - -### 1.

It has been updated to support inter-plugin dependencies and state sharing: - -```typescript -interface ResolverPlugin { - // Unique name of the plugin - name: string; - - // List of property IDs this plugin depends on - // Plugins will be processed after their dependencies - dependencies?: PropertyID[]; - - // Initialize the state for a property - initialize(): T; - - // Process a new value for the property - update( - currentState: T, - newValue: PropertyTypes, - delta: CollapsedDelta, - allStates?: Record - ): T; - - // Resolve the final value from the current state - // Must return a value of type PropertyTypes or undefined - // This is the value that will be used as the resolved property value - resolve( - state: T, - allStates?: Record - ): PropertyTypes | undefined; -} -``` - -#### Important Notes - -1. **Return Type of `resolve`**: - - The `resolve` method must return a value of type `PropertyTypes` or `undefined` - - This is different from the `update` method which returns the updated state of type `T` - - The returned value will be used as the resolved property value - -2. **Plugin Dependencies**: - - Dependencies are declared using the `dependencies` property - - Dependencies should be an array of property IDs that this plugin depends on - - The resolver ensures that all dependencies are processed before the plugin that depends on them - -3. **State Access**: - - The `allStates` parameter in `update` and `resolve` provides access to the current state of all other properties - - This allows plugins to make decisions based on the state of other properties - - The states are keyed by property ID and contain the raw state objects for each plugin - -4. **Error Handling**: - - If a plugin throws an error during initialization, update, or resolve, the error will be logged and the plugin will be skipped - - It's recommended to handle errors within the plugin methods when possible - -#### CustomResolver Class - -The `CustomResolver` class has been enhanced to: -1. Collect all plugin states before processing updates -2. Pass the complete state to each plugin during updates and resolution - -### Complex Example: Discounted Price with Dependencies - -This example demonstrates a more complex scenario with multiple interdependent plugins: - -Here's a practical example of a plugin that calculates a discounted price based on another property: - -```typescript -class DiscountedPricePlugin implements ResolverPlugin<{ price: number }> { - name = 'discounted-price'; - - initialize() { - return { price: 0 }; - } - - update( - state: { price: number }, - newValue: PropertyTypes, - _delta: CollapsedDelta, - _allStates?: Record - ) { - if (typeof newValue === 'number') { - return { price: newValue }; - } - return state; - } - - resolve( - state: { price: number }, - allStates?: Record - ): number | undefined { - // Access the discount value from another plugin's state - const discountState = allStates?.['discount'] as { value: number } | undefined; - if (discountState) { - // Apply discount if available - return state.price * (1 - (discountState.value / 100)); - } - return state.price; - } -} - -// Usage with a discount plugin -const resolver = new CustomResolver(losslessView, { - price: new DiscountedPricePlugin(), - discount: new LastWriteWinsPlugin() -}); -``` - -### Best Practices - -1. **Dependency Management**: - - Clearly document which properties your plugin depends on - - Handle cases where dependencies might be undefined - - Consider using TypeScript type guards for safer property access - -2. **Performance Considerations**: - - Access only the states you need in the `allStates` object - - Consider caching resolved values if the same calculation is performed multiple times - -3. **Testing**: - - Test plugins with and without their dependencies - - Verify behavior when dependencies are updated in different orders - - Test edge cases like missing or invalid dependencies - -### Built-in Plugins - -All built-in plugins have been updated to be compatible with the new interface: - -- `LastWriteWinsPlugin` -- `FirstWriteWinsPlugin` -- `ConcatenationPlugin` -- `MajorityVotePlugin` -- `MinPlugin` -- `MaxPlugin` - -These plugins maintain backward compatibility while supporting the new functionality. - -## Implementation Status - -The inter-plugin dependency feature has been implemented and includes: - -1. Updated `ResolverPlugin` interface with `allStates` parameter -2. Enhanced `CustomResolver` class for state sharing between plugins -3. Updated all built-in plugins for compatibility -4.

Modify CustomResolver Implementation - -#### 2.1 Update Reducer Method -Modify the `reducer` method to filter states before passing to plugins: - -```typescript -public reducer( - acc: CustomResolverAccumulator, - cur: LosslessViewOne -): CustomResolverAccumulator { - // ... existing setup code ... - - // Process each property in execution order - for (const propertyId of executionOrder) { - // ... existing delta processing ... - - // Create filtered states object with only declared dependencies - const visibleStates: Record = {}; - - // Add states for declared dependencies - if (plugin.dependencies) { - for (const dep of plugin.dependencies) { - if (allStates[dep] !== undefined) { - visibleStates[dep] = allStates[dep]; - } - } - } - - // Pass only visible states to the plugin - propertyState.state = propertyState.plugin.update( - propertyState.state, - value, - delta, - visibleStates - ); - - // ... rest of the method ... - } -} -``` - -#### 2.2 Update Resolver Method -Similarly update the `resolver` method: - -```typescript -resolver(cur: CustomResolverAccumulator): CustomResolverResult { - const res: CustomResolverResult = {}; - - for (const [entityId, entity] of Object.entries(cur)) { - const entityResult = { id: entityId, properties: {} }; - const allStates: Record = {}; - - // First pass: collect all states - for (const [propId, propState] of Object.entries(entity.properties)) { - allStates[propId] = propState.state; - } - - // Second pass: resolve each property with filtered states - for (const [propId, propState] of Object.entries(entity.properties)) { - const plugin = propState.plugin; - const visibleStates: Record = {}; - - // Only include declared dependencies - if (plugin.dependencies) { - for (const dep of plugin.dependencies) { - if (allStates[dep] !== undefined) { - visibleStates[dep] = allStates[dep]; - } - } - } - - const resolvedValue = plugin.resolve(propState.state, visibleStates); - if (resolvedValue !== undefined) { - entityResult.properties[propId] = resolvedValue; - } - } - - if (Object.keys(entityResult.properties).length > 0) { - res[entityId] = entityResult; - } - } - - return res; -} -``` - -### 3. Add Validation -Add validation to ensure dependencies exist: - -```typescript -private validateDependencies(): void { - // Existing cycle detection... - - // Add validation that all dependencies exist - for (const [pluginId, plugin] of Object.entries(this.config)) { - for (const dep of plugin.dependencies || []) { - if (!this.config[dep]) { - throw new Error(`Plugin '${pluginId}' depends on unknown property: ${dep}`); - } - } - } -} -``` - -### 4. Update Tests -1. Add tests for state visibility: - - Test that plugins only receive their declared dependencies - - Test that plugins can't access undeclared dependencies - - Test that dependency validation works - - Test that existing functionality remains unchanged - -2. Update existing tests to account for the new behavior - -## Migration Strategy -1. This is a breaking change for any plugins that were accessing undeclared dependencies -2. Add warnings in the next minor version -3. Make the behavior opt-in initially with a flag -4. In the next major version, make it the default - -## Implementation Steps -1. [ ] Add the state filtering to `reducer` -2. [ ] Add the state filtering to `resolver` -3. [ ] Update dependency validation -4. [ ] Add comprehensive tests -5. [ ] Update documentation -6. [ ] Add deprecation warnings for plugins accessing undeclared dependencies - -## Future Considerations -1. Add a debug mode that logs when plugins access undeclared dependencies -2. Consider adding granular permissions (read/write) for dependencies -3. Add support for wildcard dependencies for plugins that need access to many properties \ No newline at end of file From d7c4fda93e0e46a12d8140a94ccedfb6c2c7d6df Mon Sep 17 00:00:00 2001 From: Lentil Hoffman Date: Wed, 25 Jun 2025 06:10:34 -0500 Subject: [PATCH 21/28] refactor(resolver): overhaul plugin system and dependency handling Core Changes: - Completely rewrote CustomResolver reducer with dependency-ordered processing - Enhanced plugin initialization with proper dependency injection - Improved delta processing and property value tracking - Added robust error handling for duplicate property IDs Resolver Improvements: - Updated to use new accumulator structure - Implemented execution order processing for plugins - Enhanced debug logging and error reporting - Simplified TimestampResolver by removing unused initializer Configuration Updates: - Added TypeScript path aliases for test helpers - Improved module resolution paths Key Benefits: - More robust plugin dependency management - More efficient state updates - Enhanced type safety - Better error messages and debugging - More consistent plugin initialization This refactoring focuses on improving the robustness of the resolver, especially around plugin lifecycle management and dependency handling. The changes ensure better separation of concerns and more predictable behavior when dealing with complex plugin dependencies. --- .gitignore | 2 +- {plans => __plans__}/README.md | 0 {plans =>
