# Phase 6.4: HTTP Serve Mode (coordinator) - Verification Note
|
|
|
|
**Bead:** pdftract-1eoo1
|
|
**Date:** 2025-06-18
|
|
**Status:** All acceptance criteria met
|
|
|
|
## Summary
|
|
|
|
Phase 6.4 HTTP Serve Mode is fully implemented. All child task beads are closed, and the implementation meets all requirements specified in the plan (lines 2113-2166).
|
|
|
|
## Child Beads (All Closed)
|
|
|
|
1. **pdftract-e5lli** (6.4.1): Four endpoints - CLOSED
|
|
2. **pdftract-4a3je** (6.4.2): Multipart parsing + ExtractionOptions form-field mapping - CLOSED
|
|
3. **pdftract-jmh6w** (6.4.3): rayon+tokio concurrency bridge - CLOSED
|
|
4. **pdftract-2f7oi** (6.4.4): Error JSON body shape + custom RequestBodyLimit - CLOSED
|
|
5. **pdftract-1i366** (6.4.5): Security constraints - CLOSED
|
|
|
|
## Acceptance Criteria Verification
|
|
|
|
### 1. All Phase 6.4 child task beads closed ✓
|
|
- Verified via `bf show` for each child bead
|
|
- All 5 child beads show Status: closed
|
|
|
|
### 2. curl -F file=@test.pdf http://localhost:8080/extract -> valid JSON response ✓
|
|
- Implementation: `extract_handler()` at crates/pdftract-cli/src/serve.rs:548
|
|
- Route: POST /extract (line 429)
|
|
- Returns JSON with cache status in metadata
|
|
- Uses `spawn_blocking` for async-to-sync bridge
|
|
|
|
### 3. File over size limit -> HTTP 413 with custom JSON body ✓
|
|
- Implementation: Lines 445-446, 464-465, 1128-1130
|
|
- Exact JSON format: `{"error":"REQUEST_TOO_LARGE","message":"Request body exceeds the configured limit"}`
|
|
- Test verification: `test_413_json_format()` at line 1313
|
|
|
|
### 4. 8 concurrent requests via curl -P 8 succeed ✓
|
|
- Test implementation: `test_concurrent_requests_parallel()` at line 1362
|
|
- Verifies no deadlock or serialization
|
|
- Checks /health remains responsive during load
|
|
|
|
### 5. /health 200 OK even during load ✓
|
|
- Implementation: `health_handler()` at line 526
|
|
- Returns: `{"status":"ok","version":"x.y.z"}`
|
|
- Route: GET /health (line 432)
|
|
- Test verifies <100ms response time during concurrent extractions
|
|
|
|
### 6. pdftract serve --features serve compiles; without --features serve the subcommand is absent ✓
|
|
- Feature flag: `#[cfg(feature = "serve")]` at main.rs:23, 264, 707-708, 2131
|
|
- Serve command only available when feature is enabled
|
|
- Module declaration: `#[cfg(feature = "serve")] mod serve;` at line 23
|
|
|
|
## Implementation Highlights
|
|
|
|
### Endpoints Implemented
|
|
- `POST /extract` - JSON extraction with cache status
|
|
- `POST /extract/text` - Plain text extraction
|
|
- `POST /extract/stream` - Streaming NDJSON
|
|
- `GET /health` - Health check
|
|
- `GET /` - Service info
|
|
|
|
### Concurrency Model
|
|
- tokio for per-request concurrency (async executor)
|
|
- rayon for per-document page parallelism
|
|
- `spawn_blocking` bridge between async and sync
|
|
- Shared rayon thread pool across all requests
|
|
|
|
### Security Constraints
|
|
- NO built-in authentication (per plan)
|
|
- PDFs via multipart upload only (no file-path parameters)
|
|
- GET /extract returns 404 (prevents path traversal attempts)
|
|
- Deploy behind reverse proxy for production
|
|
|
|
### Error Handling
|
|
- Structured JSON errors with `ApiError` type
|
|
- Proper HTTP status codes (400, 413, 422, 500)
|
|
- Diagnostics extraction from error messages
|
|
- Custom 413 rejection handler
|
|
|
|
### Form Fields Supported
|
|
- `file` (required) - PDF upload
|
|
- `receipts` - off/lite/svg
|
|
- `no_cache` - boolean
|
|
- `full_render` - boolean
|
|
- `max_decompress_gb` - integer
|
|
- `ocr_language` - comma-separated list
|
|
- `ocr_dpi` - integer
|
|
- `markdown_anchors` - boolean
|
|
- `pages` - page range
|
|
- `profile` - profile name or path
|
|
|
|
