|
**Date:** 2026-02-05
|
|
**Status:** Complete
|
|
**Type:** Feature Enhancement
|
|
|
|
## Overview
|
|
|
|
Completed the implementation of the Pack Installation Workflow API endpoints and their corresponding action wrappers. The system now provides a complete API-driven architecture for pack installation, dependency analysis, environment building, and registration.
|
|
|
|
## Components Implemented
|
|
|
|
### 1. API Endpoints (attune-api)
|
|
|

|
|
- **Lines:** 1219-1296
|
|
- **Functionality:** Downloads packs from various sources (registry, Git, local)
|
|

|
|
- **Features:**
|
|
- Multi-source support (registry names, Git URLs, local paths)
|
|
- Configurable timeout and SSL verification
|
|
- Checksum validation
|
|
- Detailed success/failure reporting per pack
|
|
|
|
#### B. Get Pack Dependencies (`POST /api/v1/packs/dependencies`)

|
|
|
**Response DTOs:**

|
|
|
|
**Supporting Types:**

|
### 4. Route Registration
|
|
|
|
Routes registered in `crates/api/src/routes/packs.rs::routes()` (lines 1572-1602):
|
|
|
|
```rust
|
|
.route("/packs/download", post(download_packs))
|
|
.route("/packs/dependencies", post(get_pack_dependencies))
|
|
.route("/packs/build-envs", post(build_pack_envs))
|
|
.route("/packs/register-batch", post(register_packs_batch))
|
|
```
|
|
|
|
### 5. Documentation
|
|
|
|
Created `docs/api/api-pack-installation.md`:
|
|
- Complete API reference for all 4 endpoints
|
|
- Request/response examples
|
|
- Parameter descriptions
|
|
- Error handling guide
|
|
- Workflow integration example
|
|
- Best practices
|
|
- CLI usage examples
|
|
|
|
## Architecture Improvements
|
|
|
|
### API-First Design
|
|
- **Before:** Actions contained business logic
|
|
- **After:** Actions are thin wrappers (95% code reduction in bash)
|
|
- **Benefits:**
|
|
- Centralized logic in Rust (type-safe, testable)
|
|
- Consistent error handling
|
|
- Better security (auth, validation)
|
|
- Easier maintenance
|
|
|
|
### Consistent Error Handling
|
|
- All endpoints return structured responses
|
|
- Individual pack failures don't fail entire batch
|
|
- Detailed error messages with context
|
|
- HTTP status codes follow REST conventions
|
|
|
|
### Batch Operations
|
|
- Process multiple packs in single API call
|
|
- Per-pack result tracking
|
|
- Summary statistics
|
|
- Optimized for workflow execution
|
|
|
|
## Code Quality
|
|
|
|
### Zero Warnings
|
|
- Fixed unused import in `worker/src/service.rs` (QueueConfig)
|
|
- Fixed unused variable warning in `api/src/routes/packs.rs`
|
|
- Clean compilation: `cargo check --workspace --all-targets` ✓
|
|
|
|
### Type Safety
|
|
- All DTOs with proper Serde derives
|
|
- OpenAPI documentation via utoipa
|
|
- Compile-time query checking with SQLx
|
|
|
|
### Error Handling
|
|
- Consistent `ApiResult<T>` return types
|
|
- Proper error conversion
|
|
- Descriptive error messages
|
|
|
|
## Testing
|
|
|
|
### Manual Test Script Created
|
|
- Location: `/tmp/test_pack_api.sh`
|
|
- Tests all 4 endpoints with minimal data
|
|
- Verifies authentication
|
|
- Checks response structure
|
|
|
|
### Existing Test Infrastructure
|
|
- Action tests: `packs/core/tests/test_pack_installation_actions.sh`
|
|
- Unit test framework in place
|
|
- Integration test support
|
|
|
|
## Current Limitations & Future Work
|
|
|
|
### Environment Building
|
|
**Current State:** Detection and validation only
|
|
- Checks if Python 3 / Node.js are available
|
|
- Detects existing venv/node_modules
|
|
- Reports versions
|
|
|
|
**Future Enhancement:**
|
|
- Actual virtualenv creation
|
|
- pip install from requirements.txt
|
|
- npm/yarn install from package.json
|
|
- Containerized build environments
|
|
- Dependency caching
|
|
- Build artifact management
|
|
|
|
### Additional Planned Features
|
|
1. **Progress Streaming**
|
|
- WebSocket updates during long operations
|
|
- Real-time progress indicators
|
|
|
|
2. **Advanced Validation**
|
|
- Pack schema validation
|
|
- Dependency conflict detection
|
|
- Version compatibility checks
|
|
|
|
3. **Rollback Support**
|
|
- Pack snapshots before updates
|
|
- Automatic cleanup on failure
|
|
|
|
4. **Cache Management**
|
|
- Downloaded pack caching
|
|
- Environment reuse
|
|
- Cleanup utilities
|
|
|
|
