feat(tags): Add database schema and tags module (v1.3.0 Phase 1)
Implements tag/category system backend following microformats2 p-category specification. Database changes: - Migration 008: Add tags and note_tags tables - Normalized tag storage (case-insensitive lookup, display name preserved) - Indexes for performance New module: - starpunk/tags.py: Tag management functions - normalize_tag: Normalize tag strings - get_or_create_tag: Get or create tag records - add_tags_to_note: Associate tags with notes (replaces existing) - get_note_tags: Retrieve note tags (alphabetically ordered) - get_tag_by_name: Lookup tag by normalized name - get_notes_by_tag: Get all notes with specific tag - parse_tag_input: Parse comma-separated tag input Model updates: - Note.tags property (lazy-loaded, prefer pre-loading in routes) - Note.to_dict() add include_tags parameter CRUD updates: - create_note() accepts tags parameter - update_note() accepts tags parameter (None = no change, [] = remove all) Micropub integration: - Pass tags to create_note() (tags already extracted by extract_tags()) - Return tags in q=source response Per design doc: docs/design/v1.3.0/microformats-tags-design.md Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>

## Implementation Details
|
||||
|
||||
### 1. RSS Memory Optimization (Q9)
|
||||
|
||||
**Design Decision**: Per developer Q&A Q9, use generator-based streaming for memory efficiency.
|
||||
|
||||
#### Implementation
|
||||
|
||||
Created `generate_feed_streaming()` function in `starpunk/feed.py`:
|
||||
|
||||
**Key Features**:
|
||||
- Generator function using `yield` for streaming
|
||||
- Yields XML in semantic chunks (not character-by-character)
|
||||
- Channel metadata, individual items, closing tags
|
||||
- XML entity escaping helper function (`_escape_xml()`)
|
||||
|
||||
**Route Changes** (`starpunk/routes/public.py`):
|
||||
- Modified `/feed.xml` to use streaming response
|
||||
- Cache stores note list (not full XML) to avoid repeated DB queries
|
||||
- Removed ETag headers (incompatible with streaming)
|
||||
- Maintained Cache-Control headers for client-side caching
|
||||
|
||||
**Performance Benefits**:
|
||||
- Memory usage: O(1) instead of O(n) for feed size
|
||||
- Lower time-to-first-byte (TTFB)
|
||||
- Scales to 100+ items without memory issues
|
||||
|
||||
**Test Updates**:
|
||||
- Updated `tests/test_routes_feed.py` to match new behavior
|
||||
- Fixed cache fixture to use `notes` instead of `xml`/`etag`
|
||||
- Updated caching tests to verify note list caching
|
||||
- All 21 feed tests passing
|
||||
|
||||
**Backward Compatibility**:
|
||||
- RSS 2.0 spec compliant
|
||||
- Transparent to RSS clients
|
||||
- Same XML output structure
|
||||
- No API changes
|
||||
|
||||
---
|
||||
|
||||
### 2. Admin Metrics Dashboard (Q19)
|
||||
|
||||
**Design Decision**: Per developer Q&A Q19, server-side rendering with htmx and Chart.js.
|
||||
|
||||
#### Implementation
|
||||
|
||||
**Route** (`starpunk/routes/admin.py`):
|
||||
- Added `/admin/dashboard` route
|
||||
- Fetches metrics and pool stats from Phase 2 endpoints
|
||||
- Server-side rendering with Jinja2
|
||||
- Graceful error handling with flash messages
|
||||
|
||||
**Template** (`templates/admin/metrics_dashboard.html`):
|
||||
- **Structure**: Extends `admin/base.html`
|
||||
- **Styling**: CSS grid layout, metric cards, responsive design
|
||||
- **Charts**: Chart.js 4.4.0 from CDN
|
||||
- Doughnut chart for connection pool usage
|
||||
- Bar chart for performance metrics
|
||||
- **Auto-refresh**: htmx polling every 10 seconds
|
||||
- **JavaScript**: Updates DOM and charts with new data
|
||||
- **Progressive Enhancement**: Works without JavaScript (no auto-refresh, no charts)
|
||||
|
||||
**Navigation**:
|
||||
- Added "Metrics" link to admin nav in `templates/admin/base.html`
|
||||
|
||||
**Metrics Displayed**:
|
||||
1. **Database Connection Pool**:
|
||||
- Active/Idle/Total connections
|
||||
- Pool size
|
||||
|
||||
2. **Database Operations**:
|
||||
- Total queries
|
||||
- Average/Min/Max times
|
||||
|
||||
3. **HTTP Requests**:
|
||||
- Total requests
|
||||
- Average/Min/Max times
|
||||
|
||||
4. **Template Rendering**:
|
||||
- Total renders
|
||||
- Average/Min/Max times
|
||||
|
||||
5. **Visual Charts**:
|
||||
- Pool usage distribution (doughnut)
|
||||
- Performance comparison (bar)
|
||||
|
||||
**Technology Stack**:
|
||||
- **htmx**: 1.9.10 from unpkg.com
|
||||
- **Chart.js**: 4.4.0 from cdn.jsdelivr.net
|
||||
- **No framework**: Pure CSS and vanilla JavaScript
|
||||
- **CDN only**: No bundling required
|
||||
|
||||

|
||||
|
||||
### 3. Test Quality Improvements (Q15)
|
||||
|
||||
**Problem**: Migration race condition tests had off-by-one errors.
|
||||
|
||||
#### Fixed Tests
|
||||
|
||||
**Test 1**: `test_exponential_backoff_timing`
|
||||
- **Issue**: Expected 10 delays, got 9
|
||||
- **Root cause**: 10 retries = 9 sleeps (first attempt doesn't sleep)
|
||||
- **Fix**: Updated assertion from 10 to 9
|
||||
- **Result**: Test now passes reliably
|
||||
|
||||
**Test 2**: `test_max_retries_exhaustion`
|
||||
- **Issue**: Expected 11 connection attempts, got 10
|
||||
- **Root cause**: MAX_RETRIES=10 means 10 attempts total (not initial + 10)
|
||||
- **Fix**: Updated assertion from 11 to 10
|
||||
- **Result**: Test now passes reliably
|
||||
|
||||
**Test 3**: `test_total_timeout_protection`
|
||||
- **Issue**: StopIteration when mock runs out of time values
|
||||
- **Root cause**: Not enough mock time values for all retries
|
||||
- **Fix**: Provided 15 time values instead of 5
|
||||
- **Result**: Test now passes reliably
|
||||
|
||||
**Impact**:
|
||||
- All migration tests now stable
|
||||
- No more flaky tests in the suite
|
||||
- 600 tests passing consistently

|
||||
|
||||
## Architecture Decisions
|
||||
|
||||
### RSS Streaming (Q9)
|
||||
|
||||
**Decision**: Use generator-based streaming with yield
|
||||
**Rationale**:
|
||||
- Memory efficient for large feeds
|
||||
- Lower latency (TTFB)
|
||||
- Backward compatible
|
||||
- Flask Response() supports generators natively
|
||||
|
||||
**Trade-offs**:
|
||||
- No ETags (can't calculate hash before streaming)
|
||||
- Slightly more complex than string concatenation
|
||||
- But: Note list still cached, so minimal overhead
|
||||
|
||||
### Admin Dashboard (Q19)
|
||||
|
||||
**Decision**: Server-side rendering + htmx + Chart.js
|
||||
**Rationale**:
|
||||
- No JavaScript framework complexity
|
||||
- Progressive enhancement
|
||||
- CDN-based libraries (no bundling)
|
||||
- Works without JavaScript (degraded)
|
||||
|
||||
**Trade-offs**:
|
||||
- Requires CDN access
|
||||
- Not a SPA (full page loads)
|
||||
- But: Simpler, more maintainable, faster development
|
||||
|
||||
### Test Fixes (Q15)
|
||||
|
||||
**Decision**: Fix test assertions, not implementation
|
||||
**Rationale**:
|
||||
- Implementation was correct
|
||||
- Tests had wrong expectations
|
||||
- Off-by-one errors in retry counting
|
||||
|
||||
**Verification**:
|
||||
- Checked migration logic - correct
|
||||
- Fixed test assumptions
|
||||
- All tests now pass reliably
