# Micropub V1 Implementation Progress Report
|
||||
|
||||
**Date**: 2025-11-24
|
||||
**Branch**: `feature/micropub-v1`
|
||||
**Developer**: StarPunk Fullstack Developer Agent
|
||||
**Status**: Phase 1 Complete (Token Security)
|
||||
|
||||
## Summary
|
||||
|
||||
Implementation of Micropub V1 has begun following the architecture defined in:
|
||||
- `/home/phil/Projects/starpunk/docs/design/micropub-endpoint-design.md`
|
||||
- `/home/phil/Projects/starpunk/docs/decisions/ADR-029-micropub-indieauth-integration.md`
|
||||
|
||||
Phase 1 (Token Security) is complete with all tests passing.
|
||||
|
||||
## Work Completed
|
||||
|
||||
### Phase 1: Token Security Migration (Complete)
|
||||
|
||||
#### 1. Database Migration (002_secure_tokens_and_authorization_codes.sql)
|
||||
|
||||
**Status**: ✅ Complete and tested
|
||||
|
||||
**Changes**:
|
||||
- Dropped insecure `tokens` table (stored plain text tokens)
|
||||
- Created secure `tokens` table with `token_hash` column (SHA256)
|
||||
- Created `authorization_codes` table for IndieAuth token exchange
|
||||
- Added appropriate indexes for performance
|
||||
- Updated `SCHEMA_SQL` in `database.py` to match post-migration state
|
||||
|
||||
**Breaking Change**: All existing tokens are invalidated (required security fix)
|
||||
|
||||
#### 2. Token Management Module (starpunk/tokens.py)
|
||||
|
||||
**Status**: ✅ Complete with comprehensive test coverage
|
||||
|
||||
**Implemented Functions**:
|
||||
|
||||
**Token Generation & Hashing**:
|
||||
- `generate_token()` - Cryptographically secure token generation
|
||||
- `hash_token()` - SHA256 hashing for secure storage
|
||||
|
||||
**Access Token Management**:
|
||||
- `create_access_token()` - Generate and store access tokens
|
||||
- `verify_token()` - Verify token validity and return token info
|
||||
- `revoke_token()` - Soft revocation support
|
||||
|
||||
**Authorization Code Management**:
|
||||
- `create_authorization_code()` - Generate authorization codes
|
||||
- `exchange_authorization_code()` - Exchange codes for token info with full validation
|
||||
|
||||
**Scope Management**:
|
||||
- `validate_scope()` - Filter requested scopes to supported ones
|
||||
- `check_scope()` - Check if granted scopes include required scope
|
||||
|
||||
**Security Features**:
|
||||
- Tokens stored as SHA256 hashes (never plain text)
|
||||
- Authorization codes are single-use with replay protection
|
||||
- Optional PKCE support (code_challenge/code_verifier)
|
||||
- Proper UTC datetime handling for expiry
|
||||
- Parameter validation (client_id, redirect_uri, me must match)
|
||||
|
||||
#### 3. Test Suite (tests/test_tokens.py)
|
||||
|
||||
**Status**: ✅ 21/21 tests passing
|
||||
|
||||
**Test Coverage**:
|
||||
- Token generation and hashing
|
||||
- Access token creation and verification
|
||||
- Token expiry and revocation
|
||||
- Authorization code creation and exchange
|
||||
- Replay attack protection
|
||||
- Parameter validation (client_id, redirect_uri, me mismatch)
|
||||
- PKCE validation (S256 method)
|
||||
- Scope validation
|
||||
- Empty scope authorization (per IndieAuth spec)
|
||||
|
||||
### Technical Issues Resolved
|
||||
|
||||
#### Issue 1: Database Schema Detection
|
||||
|
||||
**Problem**: Migration system incorrectly detected fresh databases as "legacy" or "current"
|
||||
|
||||
**Solution**: Updated `is_schema_current()` in `migrations.py` to check for:
|
||||
- `authorization_codes` table existence
|
||||
- `token_hash` column in tokens table
|
||||
|
||||
This ensures fresh databases skip migrations but legacy databases apply them.
|
||||
|
||||
#### Issue 2: Datetime Timezone Mismatch
|
||||
|
||||
**Problem**: Python's `datetime.now()` returns local time, but SQLite's `datetime('now')` returns UTC
|
||||
|
||||
**Solution**: Use `datetime.utcnow()` consistently for all expiry calculations
|
||||
|
||||
**Impact**: Authorization codes and tokens now properly expire based on UTC time
|
||||
|
||||
## What's Next
|
||||
|
||||
### Phase 2: Authorization & Token Endpoints (In Progress)
|
||||
|
||||
**Remaining Tasks**:
|
||||
|
||||
1. **Token Endpoint** (`/auth/token`) - REQUIRED FOR V1
|
||||
- Exchange authorization code for access token
|
||||
- Validate all parameters (code, client_id, redirect_uri, me)
|
||||
- Optional PKCE verification
|
||||
- Return token response per IndieAuth spec
|
||||
|
||||
2. **Authorization Endpoint** (`/auth/authorization`) - REQUIRED FOR V1
|
||||
- Display authorization form
|
||||
- Require admin session
|
||||
- Generate authorization code
|
||||
- Redirect with code
|
||||
|
||||
3. **Micropub Endpoint** (`/micropub`) - REQUIRED FOR V1
|
||||
- Bearer token authentication
|
||||
- Handle create action only (V1 scope)
|
||||
- Parse form-encoded and JSON requests
|
||||
- Create notes via existing `notes.py` CRUD
|
||||
- Return 201 with Location header
|
||||
- Query endpoints (config, source, syndicate-to)
|
||||
|
||||
4. **Integration Testing**
|
||||
- Test complete flow: authorization → token exchange → post creation
|
||||
- Test with real Micropub clients (Indigenous, Quill)
|
||||
|
||||
5. **Documentation Updates**
|
||||
- Update CHANGELOG.md (breaking change)
|
||||
- Increment version to 0.10.0
|
||||
- API documentation
|
||||
|
||||
## Architecture Decisions Made
|
||||
|
||||
No new architectural decisions were required. Implementation follows ADR-029 exactly.
|
||||
|
||||
## Questions for Architect
|
||||
|
||||
None at this time. Phase 1 implementation matches the design specifications.

||||
